**Done!** The PowerPoint presentation has been created:

| File | Size | Slides |
|------|------|--------|
| `Every_Test_Has_a_Story.pptx` | 82KB | 41 slides |

## What's in the presentation:
- **Title slide** - "Every Test Has a Story"
- **Chapter 1: Frontal Impact** - Ford-UAW crash studies, Stapp's rocket sled, FMVSS 208, offset tests
- **Chapter 2: Side Impact** - Why side crashes kill differently, IIHS side test evolution
- **Chapter 3: Rollover & Roof** - Firestone/Ford case, roof crush debate
- **Chapter 4: Fire Safety & Whiplash** - Ford Pinto, FMVSS 301, BioRID dummy
- **Chapter 5: Active Safety** - AEB, pedestrian detection, ADAS testing
- **Chapter 6: Pedestrian Protection** - Euro NCAP headform tests, hood engineering
- **Chapter 7: Sports Safety** - NOCSAE founding, helmet standards, drop tower testing
- **Closing** - DTS connection and "Data Saves Lives"

## Potential Next Steps:
1. **Open and review** the PowerPoint in your presentation software
2. **Add images** from the `assets/` folder (currently text-only)
3. **Add speaker notes** for each slide
4. **Adjust styling** (colors, fonts) to match DTS branding
5. **Create alternative version** using "Data Saves Lives" theme

Would you like me to enhance the presentation further (e.g., add speaker notes, adjust formatting)?

## User

This is great. Let's put a pin in this for now. I just commited this to a git repo.

Next step I'd like to take a crack at the same general presentation, but taking a different approach.

---

## Assistant (Plan · claude-opus-4-5 · 8.3s)

Sounds good - the current presentation is saved and committed.

I'd love to hear your ideas for the alternative approach. What direction are you thinking?

Some possibilities:

1. **Audience-focused** - Tailor content differently for engineers vs. executives vs. general public
2. **Narrative structure** - Single story arc (e.g., follow one crash test dummy through history)
3. **Problem-solution format** - Start with "why do we test?" and build from there
4. **Data-forward** - Lead with striking statistics, then reveal the stories behind them
5. **Interactive/modular** - Sections that can be mixed/matched depending on audience interests
6. **Visual-first** - Design around key images/videos, with minimal text
7. **DTS-centric** - Structure around DTS products and their role in each testing domain
8. **"Day in the life"** - What happens during a single crash test, from setup to data analysis

What approach appeals to you, or do you have something else in mind?

## User

I'd like this attempt to be a similar narritive structure. I'd like to start by creating one slide per test mode. This includes all NHTSA (fmvss), IIHS, Pedestrian Protection, Sports Injury. I'd like each slide to summarize the test mode (purpose, channels, etc.) and include photos. Let's start there.

---

## Assistant (Plan · claude-opus-4-5 · 4.6s)

Got it - one slide per test mode, summarizing purpose and channels, with photos. Let me research what we have and identify all the test modes we need to cover.

00001| # Technical Standards and Specifications for Crash Testing
00002| ## SAE, ISO, and Other Engineering Standards
00003| ### Data Acquisition, Instrumentation, Injury Criteria, and Test Methods
00004| 
00005| ---
00006| 
00007| # OVERVIEW
00008| 
00009| This document covers the technical standards that govern HOW crash testing is performed - the instrumentation, data acquisition, filtering, injury calculations, and dummy specifications that underlie FMVSS and IIHS testing.
00010| 
00011| **Key Standards Organizations:**
00012| - **SAE International** - Society of Automotive Engineers (US-based, global influence)
00013| - **ISO** - International Organization for Standardization (global)
00014| - **UN/ECE** - United Nations Economic Commission for Europe
00015| - **NHTSA** - Defines injury criteria referenced by FMVSS
00016| 
00017| ---
00018| 
00019| # SAE J211: INSTRUMENTATION FOR IMPACT TEST
00020| 
00021| ## SAE J211-1: Instrumentation for Impact Test - Electronic Instrumentation
00022| 
00023| **First Published:** 1971
00024| **Current Version:** SAE J211-1 (Rev. 2014)
00025| **Scope:** Defines requirements for electronic instrumentation used in vehicle crash testing
00026| 
00027| ### Purpose
00028| SAE J211-1 ensures that crash test data is:
00029| - **Accurate** - Measurements reflect actual physical events
00030| - **Repeatable** - Same test produces same data across labs
00031| - **Comparable** - Data from different facilities can be compared
00032| - **Filtered appropriately** - High-frequency noise removed without distorting signal
00033| 
00034| ### Channel Frequency Classes (CFC)
00035| 
00036| The most important concept in J211 is **Channel Frequency Class** - the bandwidth of the measurement system.
00037| 
00038| | CFC | -3dB Frequency | Primary Use | Why This Bandwidth |
00039| |-----|----------------|-------------|-------------------|
00040| | **CFC 1000** | 1000 Hz (1650 Hz) | Head acceleration | Head impacts are high-frequency events |
00041| | **CFC 600** | 600 Hz (1000 Hz) | Chest, pelvis acceleration | Torso response is lower frequency |
00042| | **CFC 180** | 180 Hz (300 Hz) | Structural measurements | Vehicle deformation |
00043| | **CFC 60** | 60 Hz (100 Hz) | Sled displacement | Gross motion |
00044| 
00045| **Note:** The -3dB point is where signal is attenuated by 3dB (70.7%). The values in parentheses are the frequency at which attenuation reaches -40dB.
00046| 
00047| ### Filter Characteristics
00048| 
00049| SAE J211 specifies a **4th-order Butterworth low-pass filter** with specific characteristics:
00050| 
00051| | Parameter | Specification |
00052| |-----------|---------------|
00053| | Filter type | Butterworth (maximally flat) |
00054| | Filter order | 4th order (24 dB/octave rolloff) |
00055| | Phase | Zero phase shift (bi-directional filtering) |
00056| | Passband | Flat to -0.5 dB at CFC frequency |
00057| | Stopband | -24 dB at 1.67 × CFC frequency |
00058| 
00059| ### Sampling Requirements
00060| 
00061| | CFC | Minimum Sample Rate | Recommended Rate |
00062| |-----|---------------------|------------------|
00063| | CFC 1000 | 8,000 Hz | 10,000+ Hz |
00064| | CFC 600 | 4,800 Hz | 6,000+ Hz |
00065| | CFC 180 | 1,440 Hz | 2,000+ Hz |
00066| | CFC 60 | 480 Hz | 1,000+ Hz |
00067| 
00068| **Rule of thumb:** Sample at 8-10× the CFC frequency for adequate resolution.
00069| 
00070| ### Transducer Requirements
00071| 
00072| | Parameter | Specification |
00073| |-----------|---------------|
00074| | Amplitude linearity | ±1% of full scale |
00075| | Cross-axis sensitivity | <5% of primary axis |
00076| | Zero shift (post-impact) | <2% of full scale |
00077| | Frequency response | Flat to at least CFC frequency |
00078| 
00079| ### Data Channel Designation
00080| 
00081| J211 defines a naming convention for data channels:
00082| 
00083| ```
00084| [Location][Direction][Type][Filter]
00085| 
00086| Example: 11HEAD0000ACXC (Head X-acceleration, CFC 1000)
00087| ```
00088| 
00089| | Code | Meaning |
00090| |------|---------|
00091| | 11 | Driver position |
00092| | 12 | Front passenger |
00093| | 13 | Rear passenger |
00094| | HEAD | Head |
00095| | CHST | Chest |
00096| | PELV | Pelvis |
00097| | FEMR | Femur |
00098| | AC | Acceleration |
00099| | FO | Force |
00100| | MO | Moment |
00101| | X, Y, Z | Direction |
00102| 
00103| ---
00104| 
00105| ## SAE J211-2: Instrumentation for Impact Test - Photographic Instrumentation

00115| | Structural deformation | 1,000 fps | 2,000-4,000 fps |
00116| | Airbag deployment | 2,000 fps | 5,000-10,000 fps |
00117| | Detail analysis | 5,000+ fps | 10,000-40,000 fps |
00118| 
00119| ### Camera Positioning
00120| - Minimum 3 views: front, side (left or right), overhead
00121| - Additional views as needed for specific analysis
00122| - Reference markers (targets) for photogrammetric analysis
00123| - Lighting requirements for adequate exposure at high speed
00124| 
00125| ### Timing Synchronization
00126| - All cameras synchronized to common time base
00127| - Synchronization with electronic data acquisition
00128| - Timing marks visible in frame or recorded electronically
00129| - Time zero defined as first contact

00133| # ISO 6487: ROAD VEHICLES - MEASUREMENT TECHNIQUES IN IMPACT TESTS
00134| 
00135| **Equivalent to:** SAE J211-1
00136| **Current Version:** ISO 6487:2015
00137| **Scope:** International standard for crash test instrumentation
00138| 
00139| ### Relationship to SAE J211
00140| 
00141| ISO 6487 and SAE J211-1 are technically equivalent and mutually referenced. Key correspondences:
00142| 
00143| | SAE J211 CFC | ISO 6487 CFC | Application |
00144| |--------------|--------------|-------------|
00145| | CFC 1000 | CFC 1000 | Head |
00146| | CFC 600 | CFC 600 | Chest, pelvis |
00147| | CFC 180 | CFC 180 | Structure |
00148| | CFC 60 | CFC 60 | Gross motion |
00149| 
00150| ### Filter Specification (ISO 6487)
00151| 
00152| ISO 6487 defines the same 4th-order Butterworth filter with identical characteristics:
00153| 
00154| $$H(f) = \frac{1}{\sqrt{1 + (f/f_c)^{2n}}}$$
00155| 
00156| Where:
00157| - H(f) = filter transfer function
00158| - f = frequency
00159| - f_c = cutoff frequency (CFC)
00160| - n = filter order (4 for 4th order)
00161| 
00162| ### Calibration Requirements
00163| 
00164| | Parameter | Accuracy |
00165| |-----------|----------|
00166| | Acceleration | ±1.5% of full scale |
00167| | Force | ±1% of full scale |
00168| | Displacement | ±1% of full scale |
00169| | Time | ±0.01 ms |

00198| $$HIC = \left[ \frac{1}{t_2 - t_1} \int_{t_1}^{t_2} a(t) \, dt \right]^{2.5} (t_2 - t_1)$$
00199| 
00200| Where:
00201| - a(t) = resultant head acceleration (g)
00202| - t₁, t₂ = time interval (seconds)
00203| - (t₂ - t₁) = time interval maximized to find worst case
00204| 
00205| ### HIC Versions

## Assistant (Plan · claude-opus-4-5 · 18.0s)

Now I have a good picture of what we're working with. Let me clarify the scope with you before proposing a plan.

---

## Clarifying Questions

Based on my review, here are the main **test modes** I've identified. I want to confirm which ones you want slides for:

### NHTSA/FMVSS (Regulatory)
1. **FMVSS 208 - Frontal Impact** (full frontal, 35 mph)
2. **FMVSS 214 - Side Impact** (MDB + pole)
3. **FMVSS 216 - Roof Crush** (static test)
4. **FMVSS 301 - Fuel System Integrity** (rear + side impact)
5. **FMVSS 218 - Motorcycle Helmets** (drop test)
6. **FMVSS 213 - Child Restraint** (sled test)
7. **FMVSS 201 - Interior Impact** (head impact, pillars)

### IIHS (Consumer Information)
8. **IIHS Moderate Overlap Frontal** (40%, 40 mph)
9. **IIHS Small Overlap Frontal** (25%, rigid barrier)
10. **IIHS Side Impact** (heavier/faster MDB)
11. **IIHS Roof Strength** (static, 4× for Good)
12. **IIHS Head Restraint/Whiplash** (BioRID sled test)
13. **IIHS Front Crash Prevention** (AEB track test)
14. **IIHS Headlights** (track evaluation)
15. **IIHS Pedestrian AEB** (track test)

### Pedestrian Protection
16. **Euro NCAP Pedestrian** (headform/legform impactors)
17. **Euro NCAP AEB Pedestrian/Cyclist** (track test)

### Sports/Helmets (NOCSAE)
18. **Football Helmet Drop Test**
19. **Football Helmet Linear Impactor**
20. **Lacrosse/Hockey Helmets**

---

**Questions:**

1. **Should I include all of these, or a curated subset?** (e.g., skip some niche ones like FMVSS 301 fuel integrity, headlight evaluations)

2. **For "channels" - do you want the actual sensor/data channels** (e.g., "Head Ax, Ay, Az; Chest deflection; Femur load L/R...") or a **simpler summary** (e.g., "~47 channels, key metrics: HIC, chest deflection, femur load")?

3. **Photos: Should I search for additional images online**, or work with what's already in `assets/`? (Current assets are mostly dummies/pioneers, not individual test modes)

4. **Format: One slide per test = one .md file, or all slides in a single file?**

---

## User

1. All. 2. simpler summary of channel types, counts, injury calculations and criteria, etc. 3. please search for images. feel free to use items in assets/. 4. all slides in a single file

---

## Questions Before Proceeding:

1. **Does this list look complete?** Should I add or remove any tests?

2. **Grouping approach:** Should I include section divider slides between categories (e.g., "NHTSA/FMVSS Tests", "IIHS Tests", etc.), or just go slide-by-slide?

3. **Slide format consistency:** For each slide, I'm planning:
   - **Title:** Test name
   - **Purpose:** 1-2 sentences why this test exists
   - **Setup:** Speed, barrier type, angle
   - **Dummy/Instrumentation:** Which ATD, channel count
   - **Key Criteria:** Injury metrics and limits (HIC ≤ 700, chest ≤ 63mm, etc.)
   - **Image:** Photo of the test
   
   Does this structure work?

4. **Image strategy:** I'll search for official/press images from NHTSA, IIHS, Euro NCAP, NOCSAE. Want me to download them to `assets/` or just reference URLs for now?

---

## User

1. Good list, start here.
2. Divide
3. This sounds like a good plan. If you find a better plan while thinking about it, please take prudent liberties.
4. Download to assets/ please

## Assistant (Plan · claude-opus-4-5 · 32.2s)

Understood - I'm in **read-only planning mode**. Let me build out the complete plan before any execution.

---

## PLAN: Test Mode Slides Presentation

### Phase 1: Image Research & Download

I'll need to find images for each of the 27 test modes. Here's my image sourcing strategy:

| Category | Primary Sources | Image Types Needed |
|----------|-----------------|-------------------|
| **NHTSA/FMVSS** | NHTSA.gov, SaferCar.gov | Frontal crash, side MDB, pole test, roof crush rig |
| **IIHS** | IIHS.org (excellent press photos) | Small overlap, side impact, whiplash sled, AEB track |
| **Euro NCAP** | EuroNCAP.com | MPDB test, pedestrian headform/legform impactors |
| **NOCSAE/Sports** | NOCSAE.org, NFL, university labs | Drop tower, linear impactor, helmet testing |

**Existing assets we can reuse:**
- `iihs_frontal_crash_test.jpg` - good for moderate overlap
- `small_overlap_test.jpg` - IIHS small overlap
- `roof_strength_test.jpg` - roof crush
- `hybrid_iii_family.jpg`, `thor_dummy.jpg`, `worldsid_dummy.jpg` - dummy references

**Images I need to find (~20-23 new images):**
1. FMVSS 208 full frontal crash
2. FMVSS 214 side MDB impact
3. FMVSS 214 side pole impact
4. FMVSS 301 rear impact (fuel system)
5. FMVSS 208 OOP airbag test
6. FMVSS 213 child seat sled test
7. FMVSS 201 free motion headform
8. IIHS side impact (2021+ heavier barrier)
9. IIHS whiplash/BioRID sled test
10. IIHS front crash prevention (AEB track)

### Phase 2: Slide Content Structure

For each slide, I'll create content following this template:

```markdown
## [TEST NAME]
**[Category Tag]** | [Year Introduced]

**Purpose:** Why this test exists (1-2 sentences)

**Test Setup:**
- Speed: XX mph / XX km/h
- Configuration: [barrier type, angle, etc.]
- Vehicle position: [stationary/moving, orientation]

**Dummy & Instrumentation:**
- ATD: [Hybrid III 50th, SID-IIs, BioRID, etc.]
- Channels: ~XX channels
- Key sensors: [head accel, chest deflection, femur load, etc.]

**Injury Criteria & Limits:**
| Metric | Limit | Body Region |
|--------|-------|-------------|
| HIC₁₅ | ≤ 700 | Head |
| Chest deflection | ≤ 63 mm | Thorax |
| Femur load | ≤ 10 kN | Lower extremity |

**Image:** [test_name.jpg]
```

### Phase 3: File Structure

**Output file:** `test_modes_slides.md`

**Structure:**
```
# Test Modes Reference
## Automotive Safety Testing - One Slide Per Test

---

# SECTION 1: NHTSA / FMVSS TESTS
[Section divider slide]

## FMVSS 208 - Full Frontal Impact
[Slide content]

## FMVSS 214 - Side Impact (MDB)
[Slide content]

... (8 slides)

---

# SECTION 2: IIHS TESTS
[Section divider slide]

## IIHS Moderate Overlap Frontal
[Slide content]

... (8 slides)

---

# SECTION 3: NCAP TESTS
[Section divider slide]

... (3 slides)

---

# SECTION 4: PEDESTRIAN PROTECTION
[Section divider slide]

... (3 slides)

---

# SECTION 5: SPORTS / HELMET TESTING
[Section divider slide]

... (5 slides)
```

**Total:** 27 test mode slides + 5 section dividers = **32 slides**

---

### Phase 4: Optional PowerPoint Generation

After the markdown is complete, I can create a Python script to generate a `.pptx` file similar to what we did before. This would be a follow-up step.

---

## Questions Before Execution:

1. **Image format preference:** Should I try to find consistent image dimensions/orientations, or just grab the best quality available?

2. **Section divider slides:** Simple title + subtitle, or include a mini table of contents for that section?

3. **Technical depth:** For injury criteria tables, should I include ALL criteria for each test (can be 8-10 rows), or just the top 3-4 most critical ones?

4. **Naming convention for images:** I'm thinking `fmvss_208_frontal.jpg`, `iihs_small_overlap.jpg`, `nocsae_drop_tower.jpg` etc. - does that work?

5. **Ready to begin?** Once you confirm, I'll start with image research and downloads, then build the slide content.

## User

1. Best Quality
2. Mini Table of Contents
3. Start with ALL rows
4. that looks good.
5. please proceed

# The Ratings Explained

Euro NCAP introduced the overall safety rating in 2009, based on assessment in four important areas:

-   Adult Occupant Protection (for the driver and passenger);
-   Child Occupant Protection;
-   Pedestrian Protection which has been expanded to include cyclists and is now known as Vulnerable Road User (VRU) protection; and
-   Safety Assist, which evaluated driver-assistance and crash-avoidance technologies.

The overall star rating was introduced to add more flexibility to the previous ratings’ scheme which had been in use since 1997.

# Mobile Progressive Deformable Barrier

Frontal crashes are responsible for more deaths and serious injuries than any other accident type. A typical scenario is a head-on collision between two oncoming cars at moderately high speeds. In most collisions of this type, only a part of the vehicle front width structure is involved, i.e. the two colliding vehicles are offset. Accident data suggest that moderate offsets are most common in Europe.

> FRONTAL IMPACTS ARE RESPONSIBLE FOR MORE DEATHS AND SERIOUS INJURIES THAN ANY OTHER ACCIDENT TYPE

In the full-scale MPDB test, the test car is driven at 50 km/h and with 50 percent overlap into a deformable barrier mounted on an oncoming 1400 kg trolley, also travelling at 50 km/h.  The barrier represents the front end of another vehicle, getting progressively stiffer the more it is deformed.  The test replicates a crash between the test vehicle and a typical mid-size family car.  Two frontal impact dummies representing the average male are seated in the front and child dummies are placed in child restraints in the rear seats.  The dummies, vehicle and trolley are instrumented to show the forces and decelerations to which the occupants would be subjected. Especially the driver dummy in this test, THOR-50M,is a highly sophisticated and sensitive test device, developed to accurately estimate the risk of head, neck, chest and abdominal injury.  
  
Several aspects of a car’s safety are assessed in this test. To protect the test car’s occupants, crash forces have to be efficiently directed to parts of the car where the energy can be efficiently and safely absorbed. The front crumple zone must collapse in a controlled way, leaving the passenger compartment as undeformed as possible while, at the same time, not exposing the occupants to dangerously high levels of deceleration. Rearward movement of the steering wheel and the pedals must be limited if serious injuries are to be avoided. Moreover, the way in which the trolley decelerates in the impact, and the damage inflicted by the test vehicle to the deformable barrier, indicate how efficiently the two partners have interacted. A vehicle which leads to extremely high trolley decelerations or which causes very severe localised deformation is said to exhibit poor ‘compatibility’. In the real world, such vehicles may not absorb their own energy as efficiently as they should and pose a threat to other road-users.

# Head impact

About 14 percent of all road fatalities in Europe are pedestrians, with children and the elderly being at greatest risk. Pedestrians comprise one of the main categories of vulnerable road users, which also include cyclists and motorcyclists.

> ABOUT 14 PERCENT OF ALL ROAD FATALITIES IN EUROPE ARE PEDESTRIANS

Most pedestrian accidents occur within city areas where speeds are moderate. The head, the lower body and the legs are amongst the most frequently injured body regions. To estimate the potential risk of head injury in the event of a vehicle striking an adult or a child, a series of impact tests is carried out at 40 km/h using an adult or child head form impactor. Impact sites are then assessed and the protection offered is rated as good, adequate, marginal, weak or poor. 

The procedure promotes energy absorbing structures, deformation clearance and deployable protection systems such as pop-up bonnets and external airbags.

 **Introduced in 1997. **Upgraded** in 2023.**

# About our tests

We currently maintain ratings in eight tests. Click on the icons below to learn about them.

Transparency is one of the keys to the success of our ratings program. All of our **[test protocols are available here](/ratings/about-our-tests/test-protocols-and-technical-information)**.

### Discontinued tests

Our test lineup has changed over the years, as we challenge vehicle manufacturers to continually improve the safety of their products. The tests below have been discontinued; some have been replaced with more demanding versions described above. You can still find ratings from these tests for older models on our website.

### Evolution of IIHS ratings

Since our first crash tests in 1995, the ratings program has evolved to fill gaps in vehicle safety. [This document](/media/e0908220-e880-4755-8947-7138c14743c1/ONpoNw/Ratings/About%20our%20tests/Evolution%20of%20IIHS%20ratings.pdf) explains the reasons for each test program and the real-world impact it has had.

### Keeping our ratings up-to-date

Manufacturers are constantly making changes to their vehicles. Time and budget constraints make it impossible for IIHS to test every model every year. Fortunately, in many cases, we don’t need to.

Each year, we determine whether vehicles are changing in any way that could affect their performance in crash tests — for example, if modifications are being made to the structure or to airbags. Manufacturers provide this information, and we check it against information from trade journals, auto shows and other sources. If there are no changes, the rating from the previous model gets carried over.

On a case-by-case basis, we also extend ratings to models that share a platform with a rated model if there are no major differences in structure, airbags, seat belts or weight. Sometimes, we can extend ratings to plug-in hybrid variants of a rated gas vehicle, but fully electric variants must always be tested separately.

Fresh tests are needed for any vehicle that is new or has undergone big changes. In many cases, we conduct these at the IIHS Vehicle Research Center. We purchase the vehicles from dealers just like an ordinary consumer. If the test is being conducted at the manufacturer’s request and isn’t part of our regular testing schedule, then the manufacturer reimburses us for the vehicle.

However, in many situations, we don’t need to conduct the test ourselves and can instead accept data from tests conducted by manufacturers.

We don’t accept manufacturer tests for headlight evaluations or for the updated moderate overlap test. We accept manufacturer tests for other ratings in accordance with our [eligibility policy](/ratings/about-our-tests/test-protocols-and-technical-information#verified), which factors in the history of both the manufacturer and the particular model.

A key benefit of accepting manufacturer tests is that it enables us to provide consumers with more complete, up-to-date information while freeing IIHS engineers to conduct research and develop new tests.

To ensure good faith participation, we conduct occasional audit tests of vehicles that have been tested by manufacturers to make sure our results don’t differ significantly.

# Small overlap front

The small overlap front test represents a crash in which the front corner of a vehicle collides with another vehicle or an object like a tree or utility pole.

Each vehicle is tested twice — once with the overlap on the **driver side** and once on the **passenger side**. The severity of a frontal crash depends on the vehicle’s weight, so ratings in this test can only be compared among vehicles of similar weight.

### How the test is run

-   A vehicle travels at 40 mph into a rigid barrier with 25% of the vehicle’s front overlapping.
-   A Hybrid III dummy representing an average-size male is belted in the driver seat; a second one is belted in the front passenger seat for the passenger-side test.

### How vehicles are evaluated

-   We measure intrusion into the occupant compartment at key locations.
-   Sensors in the head, neck, chest, legs and feet of the dummy record injury risk.
-   High-speed film and greasepaint help us see the movement of the dummies during the crash so we can evaluate how well the seat belts and airbags work.

# Side

The side test represents a T-bone crash in which a typical modern SUV smashes into the driver side of another vehicle. The test was updated in 2021 with a more severe crash and more realistic striking rig.

Overhead view of the test and the real-world scenario it is based on

### How the test is run

-   A 4,200-pound striking rig, known as the moving deformable barrier, with the approximate height of the front bumper and grille of a modern SUV hits the driver side of the test vehicle at 37 mph.
-   The rig is equipped with a deformable honeycomb surface that bends around the B-pillar between the front and rear doors like the front end of a real SUV.
-   A SID-IIs dummy the size of a small woman or 12-year-old child is belted in the driver seat, and another is belted in the second row behind the driver.

### How vehicles are evaluated

-   We measure intrusion into the occupant compartment at key locations.
-   Sensors in the head, neck, torso and pelvis of the dummies record injury risk.
-   High-speed film and greasepaint help us see whether the dummies’ heads contacted or came near any hard parts of the vehicle or the barrier. If the vehicle’s airbags and seat belts perform correctly, the only place the paint should end up is on the airbags.

# Head restraints

Discontinued test

Head restraints are important for preventing neck injury. Our dynamic test consisted of a simulated rear impact similar to a stationary vehicle being struck at 20 mph by a vehicle of the same weight.

### How the test was run

Before testing head restraints, we measured them to make sure they were high enough and close enough to an average-size male’s head to perform well. If a head restraint had good or acceptable geometry, it was put through the dynamic test. For the simulated impact, the vehicle’s seat was placed on the testing rig, and a BioRID dummy was placed in the seat.

### How vehicles were evaluated

-   Head restraint height and backset were factored in.
-   We measured how quickly the head contacted the head restraint and the dummy's torso acceleration during the impact.
-   The dummy also recorded maximum neck shear force and maximum neck tension.

### Why we stopped conducting this test

We discontinued the head restraint test after almost all models began earning good ratings. IIHS researchers are developing a more challenging test to help drive further improvements.

# Front crash prevention: vehicle-to-vehicle

The vehicle-to-vehicle front crash prevention test evaluates the effectiveness of forward collision warning and automatic emergency braking. The current version represents front-to-rear crash scenarios in which a vehicle approaches a passenger car, motorcycle or large truck that is stopped in the roadway from behind.

![Passenger vehicle configuration](/media/e14a92ce-aa81-4917-ae52-0da0de797b7b/MmBTZg/Ratings/About%20our%20tests/New%20images%20Aug%202024/FCP%20veh-to-veh/FCP%203%20target%20drawings_passenger%20vehicle%20target.png)

**Passenger car target:** Both warning and automatic braking are tested with the target in the center of the lane and offset to the right or left.

![Motorcycle configuration](/media/429ede7b-308d-4d21-9c33-d5c8ccbc54f3/InirYA/Ratings/About%20our%20tests/New%20images%20Aug%202024/FCP%20veh-to-veh/FCP%203%20target%20drawings_motorcycle%20target.png)

**Motorcycle target:** Both warning and automatic braking are tested with the target in the center of the lane and offset to the right or left.

![Dry van configuration](/media/ef02babf-1a4b-4ac7-be22-50f03da8d687/pG-hkg/Ratings/About%20our%20tests/New%20images%20Aug%202024/FCP%20veh-to-veh/FCP%203%20target%20drawings_Dry%20van%20target.png)

**Semitrailer:** Only the warning is tested. The trailer is always in the center of the lane.

### How the test is run

-   A technician drives the test vehicle toward stationary targets designed to simulate the back of a passenger car and a motorcycle as well as an actual dry van trailer without touching the brake pedal.
-   A GPS system, onboard camera and other sensors record when the forward collision warning alert occurs, how much the vehicle slows to avoid or mitigate a collision and other data.
-   Multiple trials are conducted with each target at speeds of 31, 37 and 43 mph.
-   At each speed, trials are conducted with the motorcycle or passenger car target positioned in the center of the travel lane and offset to the left or right.
-   If the test vehicle fails to achieve a minimum speed reduction at the slower test speeds, only the forward collision warning system is evaluated in the higher-speed tests.
-   The dry van trailer is always positioned in the center of the lane. Only the forward collision warning system is evaluated, and the driver steers out of the lane to avoid a crash.

### How vehicles are evaluated

-   Points are awarded for warnings that occur at least 2.1 seconds before the projected time of impact and for substantial speed reductions in the tests with the surrogate targets, based on the average achieved in three test runs.
-   Speed reductions account for two-thirds and warnings account for one-third of the maximum possible score.
-   In general, vehicles must issue timely warnings in all the scenarios and slow substantially or avoid a collision altogether in the braking tests to earn a good rating.

   - Name them consistently: `fmvss_208_frontal.jpg`, `iihs_side_2021.jpg`, etc.

2. **Create slide content** in `test_modes_slides.md`
   - 5 section dividers with mini table of contents
   - 27 test mode slides with full details
   - All injury criteria tables populated

3. **Optional: Generate PowerPoint** 
   - Create Python script to convert markdown to `.pptx`
   - Include images on each slide

Those are also failing (HTML error pages). NHTSA's website blocks direct downloads. Let me focus on what we have and use the existing assets effectively. I'll proceed to create the markdown document - we have good images from IIHS and Euro NCAP, plus the existing assets. I can note where additional images are needed.

**Tool: bash**

**Input:**
```json
{
  "command": "rm assets/ncap_frontal_test.jpg assets/ncap_side_pole.jpg 2>/dev/null; ls -la assets/*.jpg assets/*.png 2>/dev/null | awk '$5 > 5000 {print $9, $5}' | sort",

FMVSS 208 - Full Frontal Impact\n2. FMVSS 214 - Side Impact (MDB)\n3. FMVSS 214 - Side Pole Impact\n4. FMVSS 216 - Roof Crush Resistance\n5. FMVSS 301 - Fuel System Integrity\n6. FMVSS 208 - Out-of-Position (OOP) Testing\n7. FMVSS 213 - Child Restraint Systems\n8. FMVSS 201 - Interior Impact (Free Motion Headform)\n\n**These are mandatory compliance tests required for vehicles sold in the United States.**\n\n---\n\n## FMVSS 208 - Full Frontal Impact\n**NHTSA** | Introduced: 1968 (crash test 1984) | Full Vehicle Crash Test\n\n### Purpose\nEvaluates occupant protection in head-on collisions. The most fundamental crash test - simulates a vehicle striking a fixed barrier (like a concrete wall) at highway speed. Forms the basis of the NCAP 5-star rating system.\n\n### Test Setup\n| Parameter | Value |\n|-----------|-------|\n| Speed | 35 mph (56 km/h) |\n| Barrier | Rigid concrete wall |\n| Overlap | 100% full width |\n| Vehicle | Production vehicle |\n| Orientation | Perpendicular to barrier |\n\n### Dummy & Instrumentation\n| Item | Specification |\n|------|---------------|\n| Driver ATD | Hybrid III 50th percentile male |\n| Passenger ATD | Hybrid III 5th percentile female |\n| Total Channels | ~94 (47 per dummy) |\n| Key Sensors | Head triaxial accel, chest accel, chest deflection, femur load cells, neck load cells |\n\n### Injury Criteria & Limits\n| Metric | Limit | Body Region | CFC |\n|--------|-------|-------------|-----|\n| HIC₁₅ | ≤ 700 | Head | 1000 |\n| HIC₃₆ | ≤ 1000 | Head | 1000 |\n| Peak Head Accel (3ms) | ≤ 80g | Head | 1000 |\n| Chest Accel (3ms) | ≤ 60g | Thorax | 180 |\n| Chest Deflection | ≤ 63 mm (50th) / 52 mm (5th) | Thorax | 600 |\n| Femur Load | ≤ 10 kN | Lower Extremity | 600 |\n| Nij (all modes) | ≤ 1.0 | Neck | 600 |\n| Neck Tension | ≤ 4,170 N (50th) | Neck | 600 |\n| Neck Compression | ≤ 4,000 N | Neck | 600 |\n\n**Image:** `assets/crash_test_dummies_subaru.jpg`\n\n---\n\n## FMVSS 214 - Side Impact (Moving Deformable Barrier)\n**NHTSA** | Introduced: 1990 (dynamic) | Full Vehicle Crash Test\n\n### Purpose\nEvaluates occupant protection when struck broadside by another vehicle. Side impacts are particularly dangerous because there is minimal crush space between the door and the occupant - only inches separate life and death.\n\n### Test Setup\n| Parameter | Value |\n|-----------|-------|\n| MDB Speed | 33.5 mph (54 km/h) |\n| MDB Mass | 3,015 lb (1,368 kg) |\n| MDB Angle | 27° crabbed (not perpendicular) |\n| Impact Point | Driver side, centered on H-point |\n| Target Vehicle | Stationary |\n| Barrier Face | Deformable aluminum honeycomb |\n\n### Dummy & Instrumentation\n| Item | Specification |\n|------|---------------|\n| Driver ATD | ES-2re (Euro SID - rib extension) |\n| Rear ATD | SID-IIs (5th percentile female) |\n| Total Channels | ~80 |\n| Key Sensors | Head accel, rib deflections (3 levels), pelvis accel, abdominal force |\n\n### Injury Criteria & Limits\n| Metric | Limit | Body Region | CFC |\n|--------|-------|-------------|-----|\n| HIC₃₆ | ≤ 1000 | Head | 1000 |\n| Lower Spine Accel | ≤ 82g (ES-2re) | Pelvis | 1000 |\n| Rib Deflection | ≤ 44 mm (any rib) | Thorax | 600 |\n| Abdominal Force | ≤ 2.5 kN | Abdomen | 600 |\n| Pubic Force | ≤ 6 kN | Pelvis | 600 |\n| V*C (Viscous) | ≤ 1.0 m/s | Thorax | - |\n\n**Image:** `assets/iihs_side_barrier.jpg`\n\n---\n\n## FMVSS 214 - Side Pole Impact\n**NHTSA** | Introduced: 2007 | Full Vehicle Crash Test\n\n### Purpose\nSimulates a vehicle sliding sideways into a narrow fixed object like a tree or utility pole. These crashes concentrate force on a small area, causing severe intrusion. Added after recognizing that MDB tests alone didn't capture this failure mode.\n\n### Test Setup\n| Parameter | Value |\n|-----------|-------|\n| Speed | 20 mph (32 km/h) |\n| Pole Diameter | 254 mm (10 inches) |\n| Impact Angle | 75° (oblique, not perpendicular) |\n| Impact Location | Driver's head position |\n| Vehicle Movement | Vehicle propelled into stationary pole |\n\n### Dummy & Instrumentation\n| Item | Specification |\n|------|---------------|\n| Driver ATD | ES-2re or WorldSID |\n| Total Channels | ~40 |\n| Key Sensors | Head accel, thorax ribs, pelvis accel |\n\n### Injury Criteria & Limits\n| Metric | Limit | Body Region | CFC |\n|--------|-------|-------------|-----|\n| HIC₃₆ | ≤ 1000 | Head | 1000 |\n| Rib Deflection | ≤ 44 mm | Thorax | 600 |\n| Lower Spine Accel | ≤ 82g | Pelvis | 1000 |\n| Abdominal Force | ≤ 2.5 kN | Abdomen | 600 |\n\n**Note:** Side curtain airbags became critical for passing this test.\n\n**Image:** `assets/iihs_side_2021.jpg`\n\n---\n\n## FMVSS 216 - Roof Crush Resistance\n**NHTSA** | Introduced: 1973 (1.5×), Upgraded 2009 (3×) | Static Test\n\n### Purpose\nEnsures the roof structure can support the vehicle's weight during a rollover, preventing catastrophic collapse onto occupants' heads. The 2009 upgrade doubled the strength requirement after research showed the original standard was inadequate.\n\n### Test Setup\n| Parameter | Value |\n|-----------|-------|\n| Test Type | Static (no crash) |\n| Force Application | Angled steel plate |\n| Plate Angle | 25° from horizontal |\n| Force Required | ≥ 3× vehicle unloaded weight |\n| Test Duration | Force maintained for 5 seconds |\n| Tested Area | Both driver and passenger sides |\n\n### Instrumentation\n| Item | Specification |\n|------|---------------|\n| ATD | None (static test) |\n| Measurements | Applied force, roof displacement |\n| Channels | ~4-6 |\n| Key Sensors | Load cells under plate, displacement transducers |\n\n### Performance Criteria\n| Metric | Requirement |\n|--------|-------------|\n| Strength-to-Weight Ratio | ≥ 3.0 |\n| Maximum Displacement | ≤ 127 mm (5 inches) before reaching 3× |\n| Both Sides | Must pass independently |\n\n**Historical Note:** The original 1.5× standard was criticized as too weak. After the Ford Explorer/Firestone rollover crisis, the 2009 upgrade to 3× was implemented.\n\n**Image:** `assets/roof_strength_test.jpg`\n\n---\n\n## FMVSS 301 - Fuel System Integrity\n**NHTSA** | Introduced: 1968, Revised 1977 (post-Pinto) | Full Vehicle Crash Test\n\n### Purpose\nPrevents fuel leakage after crashes to reduce fire risk. The infamous Ford Pinto case (fuel tank rupturing in rear impacts) led to strengthened requirements in 1977.\n\n### Test Setup - Rear Impact\n| Parameter | Value |\n|-----------|-------|\n| Speed | 50 mph (80 km/h) - rear moving barrier |\n| Barrier Mass | 4,000 lb (1,814 kg) |\n| Configuration | MDB strikes rear of stationary vehicle |\n\n### Test Setup - Side Impact\n| Parameter | Value |\n|-----------|-------|\n| Speed | 20 mph (32 km/h) |\n| Configuration | MDB strikes side |\n\n### Test Setup - Rollover\n| Parameter | Value |\n|-----------|-------|\n| Procedure | Vehicle rotated 360° |\n| Duration | Hold at 90°, 180°, 270° positions |\n\n### Instrumentation\n| Item | Specification |\n|------|---------------|\n| ATD | None (fuel leakage test) |\n| Measurements | Fuel leakage volume |\n| Duration | 5 minutes post-crash for static leak |\n\n### Performance Criteria\n| Metric | Limit |\n|--------|-------|\n| Fuel Leakage (impact) | ≤ 28g during impact |\n| Fuel Leakage (static) | ≤ 142g/min post-crash |\n| Rollover Leakage | ≤ 142g/min at each position |\n\n**Historical Note:** \"It's cheaper to let them burn\" memo from Ford became infamous. Estimated $11 fix vs. $200M in settlements.\n\n**Image:** `assets/cadaver_crash_test.jpg` (for general crash imagery)\n\n---\n\n## FMVSS 208 - Out-of-Position (OOP) Testing\n**NHTSA** | Introduced: 2000 (Advanced Airbag Rule) | Static Deployment Test\n\n### Purpose\nEnsures airbags don't injure or kill occupants who are too close to the airbag at deployment. After 175+ deaths from early aggressive airbags (mostly children and small adults), this test was added.\n\n### Test Configurations\n| Position | Description |\n|----------|-------------|\n| Position 1 | Chin on airbag module (close proximity) |\n| Position 2 | Chest on airbag module |\n| Position 3 | Abdomen on airbag module |\n| Position 4 | Child seat in front passenger position |\n\n### Dummy & Instrumentation\n| Item | Specification |\n|------|---------------|\n| ATDs Used | Hybrid III 5th female, 6-year-old, 3-year-old, 12-month CRABI |\n| Total Channels | ~30 per test |\n| Key Sensors | Head/neck loads, chest deflection |\n\n### Injury Criteria & Limits (5th Female)\n| Metric | Limit | Body Region |\n|--------|-------|-------------|\n| HIC₁₅ | ≤ 700 | Head |\n| Nij | ≤ 1.0 | Neck |\n| Neck Tension | ≤ 2,620 N | Neck |\n| Chest Deflection | ≤ 52 mm | Thorax |\n\n### Key Requirements\n- Suppression: Airbag must suppress for rear-facing child seats\n- Depowering: Lower inflation force than pre-1998 airbags\n- Multi-stage: Variable deployment force based on crash severity\n\n**Image:** `assets/crabi_infant_dummy.jpg`\n\n---\n\n## FMVSS 213 - Child Restraint Systems\n**NHTSA** | Introduced: 1971, Revised Multiple Times | Sled Test\n\n### Purpose\nEnsures child car seats protect children in crashes. Tests the child restraint system itself, not the vehicle.\n\n### Test Setup\n| Parameter | Value |\n|-----------|-------|\n| Test Type | Sled test (simulated crash) |\n| Delta-V | 30 mph (48 km/h) |\n| Peak G | 23-26g |\n| Pulse Duration | ~80 ms |\n| Seat Bench | Standardized test bench |\n\n### Dummy Types by Size\n| Dummy | Represents | Weight |\n|-------|------------|--------|\n| CRABI 12-month | 12-month infant | 22 lb (10 kg) |\n| Hybrid III 3-year-old | Toddler | 33 lb (15 kg) |\n| Hybrid III 6-year-old | Child | 51 lb (23 kg) |\n| Hybrid III 10-year-old | Older child | 79 lb (36 kg) |\n\n### Instrumentation\n| Item | Specification |\n|------|---------------|\n| Total Channels | ~15-20 per dummy |\n| Key Sensors | Head accel, chest accel, head excursion |\n\n### Injury Criteria & Limits\n| Metric | Limit | Notes |\n|--------|-------|-------|\n| HIC₃₆ | ≤ 1000 | All dummies |\n| Head Excursion | ≤ 720 mm | Distance traveled forward |\n| Knee Excursion | ≤ 915 mm | Distance traveled forward |\n| Chest Accel (3ms) | ≤ 60g | All dummies |\n\n**Image:** `assets/child_dummy_booster.jpg`\n\n---\n\n## FMVSS 201 - Interior Impact (Free Motion Headform)\n**NHTSA** | Introduced: 1968, Upgraded 1998 (Upper Interior) | Component Test\n\n### Purpose\nEnsures interior surfaces (A-pillar, B-pillar, roof rail, header) don't cause severe head injury when occupants strike them during crashes. Led to padded pillars and roof-mounted airbags.\n\n### Test Setup\n| Parameter | Value |\n|-----------|-------|\n| Test Type | Component (not full vehicle crash) |\n| Impactor | Free Motion Headform (FMH) |\n| FMH Mass | 4.5 kg (10 lb) |\n| Impact Speed | 15 mph (24 km/h) |\n| Target Areas | A-pillar, B-pillar, C-pillar (if present), roof rail, header |\n\n### Instrumentation\n| Item | Specification |\n|------|---------------|\n| FMH Sensors | Triaxial accelerometer |\n| Total Channels | 3 (x, y, z acceleration) |\n| Sample Rate | ≥ 8,000 Hz |\n| Filter | CFC 1000 |\n\n### Injury Criteria\n| Metric | Limit | Location |\n|--------|-------|----------|\n| HIC(d) | ≤ 1000 | All target points |\n\n**Note:** HIC(d) is a modified HIC calculation for the FMH test.\n\n### Test Point Grid\n- Multiple impact points mapped across each pillar/header\n- Each point tested separately\n- All points must pass\n\n**Image:** `assets/iihs_dummy_sensors.jpg`\n\n---\n\n# SECTION 2: IIHS CONSUMER INFORMATION TESTS\n\n## Tests in This Section:\n1. IIHS Moderate Overlap Frontal\n2. IIHS Small Overlap Frontal (Driver + Passenger)\n3. IIHS Side Impact (2021 Updated)\n4. IIHS Roof Strength\n5. IIHS Head Restraint / Whiplash (Discontinued 2020)\n6. IIHS Front Crash Prevention - Vehicle to Vehicle\n7. IIHS Headlights\n8. IIHS Front Crash Prevention - Pedestrian\n\n**IIHS tests are voluntary consumer information ratings (Good/Acceptable/Marginal/Poor), not regulatory requirements.**\n\n---\n\n## IIHS Moderate Overlap Frontal\n**IIHS** | Introduced: 1995 | Full Vehicle Crash Test\n\n### Purpose\nSimulates a head-on crash where only part of each vehicle's front structure is engaged - the most common type of serious frontal crash. More demanding than the FMVSS 208 full-frontal test because it bypasses part of the crush structure.\n\n### Test Setup\n| Parameter | Value |\n|-----------|-------|\n| Speed | 40 mph (64 km/h) |\n| Overlap | 40% of vehicle width |\n| Barrier | Deformable aluminum honeycomb |\n| Barrier Height | 650 mm |\n| Barrier Width | 1,000 mm |\n| Barrier Depth | Progressive crush stiffness |\n\n### Dummy & Instrumentation\n| Item | Specification |\n|------|---------------|\n| Driver ATD | Hybrid III 50th percentile male |\n| Total Channels | ~47 |\n| Key Sensors | Head accel, neck loads, chest accel/deflection, femur loads, tibia loads |\n\n### Injury Criteria Assessment\n| Body Region | Good | Acceptable | Marginal | Poor |\n|-------------|------|------------|----------|------|\n| Head/Neck | Low risk | Elevated risk | High risk | Very high risk |\n| Chest | Low risk | Elevated risk | High risk | Very high risk |\n| Hip/Thigh | Low risk | Elevated risk | High risk | Very high risk |\n| Lower Leg/Foot | Low risk | Elevated risk | High risk | Very high risk |\n\n### Structural Assessment\n- Intrusion measurements at multiple points\n- Steering column displacement\n- Door opening post-crash\n- Fuel system integrity\n\n**Image:** `assets/iihs_frontal_crash_test.jpg`\n\n---\n\n## IIHS Small Overlap Frontal\n**IIHS** | Introduced: 2012 (Driver), 2017 (Passenger) | Full Vehicle Crash Test\n\n### Purpose\nAddresses crashes where only the corner of the vehicle hits an object (tree, pole, corner of another vehicle).

## FMVSS 208 - Full Frontal Impact
**NHTSA** | Introduced: 1968 (crash test 1984) | Full Vehicle Crash Test

### Purpose
Evaluates occupant protection in head-on collisions. The most fundamental crash test - simulates a vehicle striking a fixed barrier (like a concrete wall) at highway speed. Forms the basis of the NCAP 5-star rating system.

### Test Setup
| Parameter | Value |
|-----------|-------|
| Speed | 35 mph (56 km/h) |
| Barrier | Rigid concrete wall |
| Overlap | 100% full width |
| Vehicle | Production vehicle |
| Orientation | Perpendicular to barrier |

### Dummy & Instrumentation
| Item | Specification |
|------|---------------|
| Driver ATD | Hybrid III 50th percentile male |
| Passenger ATD | Hybrid III 5th percentile female |
| Total Channels | ~94 (47 per dummy) |
| Key Sensors | Head triaxial accel, chest accel, chest deflection, femur load cells, neck load cells |

### Injury Criteria & Limits
| Metric | Limit | Body Region | CFC |
|--------|-------|-------------|-----|
| HIC₁₅ | ≤ 700 | Head | 1000 |
| HIC₃₆ | ≤ 1000 | Head | 1000 |
| Peak Head Accel (3ms) | ≤ 80g | Head | 1000 |
| Chest Accel (3ms) | ≤ 60g | Thorax | 180 |
| Chest Deflection | ≤ 63 mm (50th) / 52 mm (5th) | Thorax | 600 |
| Femur Load | ≤ 10 kN | Lower Extremity | 600 |
| Nij (all modes) | ≤ 1.0 | Neck | 600 |
| Neck Tension | ≤ 4,170 N (50th) | Neck | 600 |
| Neck Compression | ≤ 4,000 N | Neck | 600 |

## FMVSS 214 - Side Impact (Moving Deformable Barrier)
**NHTSA** | Introduced: 1990 (dynamic) | Full Vehicle Crash Test

### Purpose
Evaluates occupant protection when struck broadside by another vehicle. Side impacts are particularly dangerous because there is minimal crush space between the door and the occupant - only inches separate life and death.

### Test Setup
| Parameter | Value |
|-----------|-------|
| MDB Speed | 33.5 mph (54 km/h) |
| MDB Mass | 3,015 lb (1,368 kg) |
| MDB Angle | 27° crabbed (not perpendicular) |
| Impact Point | Driver side, centered on H-point |
| Target Vehicle | Stationary |
| Barrier Face | Deformable aluminum honeycomb |

### Dummy & Instrumentation
| Item | Specification |
|------|---------------|
| Driver ATD | ES-2re (Euro SID - rib extension) |
| Rear ATD | SID-IIs (5th percentile female) |
| Total Channels | ~80 |
| Key Sensors | Head accel, rib deflections (3 levels), pelvis accel, abdominal force |

### Injury Criteria & Limits
| Metric | Limit | Body Region | CFC |
|--------|-------|-------------|-----|
| HIC₃₆ | ≤ 1000 | Head | 1000 |
| Lower Spine Accel | ≤ 82g (ES-2re) | Pelvis | 1000 |
| Rib Deflection | ≤ 44 mm (any rib) | Thorax | 600 |
| Abdominal Force | ≤ 2.5 kN | Abdomen | 600 |
| Pubic Force | ≤ 6 kN | Pelvis | 600 |
| V*C (Viscous) | ≤ 1.0 m/s | Thorax | - |

Would you like me to:
1. Adjust any slide content or formatting?
2. Add additional test modes?
3. Create a different variant of the presentation?

## User

3. What are some ideas for an entertaining and informative 45-minute presentation from a field service and application engineer? He would like to engage the engineering and other internal staff of how DTS customers use their equipment, inspire a sense of helping humanity, and help inform good engineering decisions in the future.

---

## Assistant (Build · claude-opus-4-5 · 46.2s)

Great question! Let me brainstorm some compelling presentation concepts for Ben that leverage his field experience while connecting to the bigger picture of saving lives.

---

## Presentation Concept Ideas for DTS Internal Staff

### Concept 1: "The Data Behind the Headlines"
**Angle:** Connect famous crashes/safety stories to the actual DTS data that drove change

**Structure:**
- Show a news headline (e.g., "Ford Explorer Rollover Crisis")
- Reveal: "Here's what the data actually showed"
- Walk through real crash test data traces
- Show the engineering fix that resulted
- End with lives saved statistics

**Engagement:** Quiz staff - "What do you think this spike means?" before revealing

---

### Concept 2: "A Day in the Life of a Data Channel"
**Angle:** Follow a single measurement from sensor to regulation

**Story arc:**
1. A child is killed by an airbag (real 1990s tragedy)
2. Engineers ask: "How do we measure what's happening?"
3. DTS accelerometer captures the event
4. Data reveals the problem (deployment force too high for small occupants)
5. New OOP tests created
6. Multi-stage airbags developed
7. Deaths drop from 50+/year to near zero

**Engagement:** Interactive - have staff guess what injury criterion was created

---

### Concept 3: "Customers You Didn't Know You Had"
**Angle:** Surprising applications of DTS equipment

**Segments (5-7 minutes each):**

**Duration:** 45 minutes

**Structure:**

### Opening (5 min)
- Powerful statistic: "This data represents someone's mother, father, child"
- Show a crash test video with the human context

### Part 1: The Headlines (15 min)
Pick 3 major safety stories and show the data connection:
1. **Airbag crisis** → DTS OOP testing data → depowering solution
2. **IIHS small overlap** → structural data → industry redesign
3. **Football helmet standard** → SI measurements → 90% fatality reduction

### Part 2: Surprising Applications (10 min)
Quick hits of unexpected uses:
- Military blast testing
- Sports equipment
- Theme park safety
- Medical devices
- Space exploration

### Part 3: The Engineering Impact (10 min)

- Show a "bad" data trace and diagnose it
- Discuss calibration and quality
- Connect to product decisions: "This is why X feature matters"

### Closing (5 min)
- Return to the human element
- Total lives saved by crash testing (~117,000/year vs 1970 rates)
- "Every channel you design, every product you build, is part of this"

### Engagement Techniques

| Technique | When to Use |
|-----------|-------------|
| **Live polling** | "What do you think caused this?" |
| **Data trace quiz** | "Identify the injury" from waveform |
| **Video clips** | Real crash tests (dramatic, memorable) |
| **Before/after** | Car designs pre/post regulation |
| **Guest appearance** | Customer testimonial video? |
| **Physical props** | Bring a sensor, dummy part, damaged component |
| **Storytelling** | Names and faces, not just statistics |

---

### Key Messages to Convey

1. **Your work matters.** Every product decision affects real safety outcomes.
2. **Data quality = life quality.** Bad data leads to bad engineering decisions.
3. **We're part of something bigger.** DTS equipment is in every major crash lab worldwide.
4. **The work isn't done.** New challenges: EVs, autonomous vehicles, vulnerable road users.
5. **Pride in craft.** Show the rigor and precision that goes into testing.

Every data channel represents a human life\n2. Good data enables good engineering decisions\n3. DTS equipment is part of a global life-saving mission\n4. The work isn't done - new challenges await\n\n---\n\n# SLIDE-BY-SLIDE SCRIPT AND SPEAKER NOTES\n\n---\n\n## SLIDE 1: Title Slide\n**Title:** The Stories Our Data Tells  \n**Subtitle:** How DTS Helps Save Lives\n\n### Speaker Notes:\n> *[Walk to center stage, pause, make eye contact with audience]*\n> \n> Good morning everyone. I'm Ben, and I've spent the last [X] years as a field application engineer, which means I get to see something most of you don't - I get to see what happens to our equipment after it leaves this building.\n> \n> Today I want to share some stories with you. Not technical specifications or product roadmaps - stories. Because behind every data channel we design, every product we ship, every calibration we perform... there's a human story.\n> \n> Let me start with a number.\n\n---\n\n## SLIDE 2: The Number That Matters\n**Visual:** Large \"117,000\" in center  \n**Subtitle:** Lives saved every year in the U.S. alone\n\n### Speaker Notes:\n> One hundred seventeen thousand.\n> \n> That's how many people are alive today, this year, who would have died on American roads if we still had 1970s vehicle safety.\n> \n> In 1970, the fatality rate was 4.7 deaths per 100 million vehicle miles traveled. Today it's about 1.1. Same roads. More cars. More miles. But 77% fewer deaths per mile driven.\n> \n> *[Pause]*\n> \n> That didn't happen by accident. It happened because of data. Data that came from instrumentation. Instrumentation that companies like DTS build.\n> \n> Every accelerometer we ship, every data acquisition system we calibrate, every channel of data we help capture - it's part of this.\n\n---\n\n## SLIDE 3: A Crashed Car is Gone Forever\n**Visual:** Photo of crashed test vehicle  \n**Quote:** \"A crashed car is destroyed in milliseconds. The data is what remains.\"\n\n### Speaker Notes:\n> Here's something I tell customers all the time: A crashed car is gone forever. In about 150 milliseconds, a $50,000 test vehicle becomes scrap metal.\n> \n> But the data? The data lives on. The data gets analyzed, debated, published. The data drives regulation. The data changes designs. The data saves the next generation of occupants.\n> \n> That's what we do. We're not just building data acquisition systems. We're building the memory of every crash test ever run.\n> \n> Let me show you what I mean with three stories from the field.\n\n---\n\n## SLIDE 4: Part 1 - The Headlines\n**Visual:** Section divider  \n**Title:** PART 1: The Data Behind the Headlines\n\n### Speaker Notes:\n> You've all seen safety recalls in the news. You've seen crash test ratings. You've maybe heard about the airbag crisis or the Ford Explorer rollovers.\n> \n> What you might not know is that behind every one of those headlines, there's data. Specific data. Data channels that revealed what was happening. Data that DTS equipment helped capture.\n> \n> Let me take you behind three headlines.\n\n---\n\n## SLIDE 5: Story 1 - The Airbag That Killed\n**Visual:** Newspaper headline - \"Airbag Kills Child in Minor Crash\"  \n**Subtitle:** 1990s Airbag Crisis\n\n### Speaker Notes:\n> *[Pause for effect]*\n> \n> 1996. A mother is driving her 6-year-old daughter to school. They're rear-ended at maybe 15 miles per hour. A minor fender-bender.\n> \n> The airbag deploys. The child, sitting in the front seat, is killed instantly.\n> \n> This wasn't a freak accident. Between 1990 and 1997, airbags killed over 175 people - mostly children and small adults. The very safety device designed to save them was killing them.\n> \n> The question everyone was asking: Why?\n\n---\n\n## SLIDE 6: What the Data Revealed\n**Visual:** Data trace showing airbag deployment force - high spike  \n**Annotation:** Peak inflation force, deployment timing\n\n### Speaker Notes:\n> Here's what the data showed.\n> \n> *[Point to trace]*\n> \n> This is an airbag deployment trace. Look at that spike. Early airbags were designed for one scenario: an unbelted 50th percentile male in a 30 mph crash. They inflated with explosive force - about 200 mph.\n> \n> But who was actually getting hit by these airbags? Children. Small women. People sitting too close to the steering wheel.\n> \n> The data from out-of-position testing - using accelerometers like ours in small female dummies and child dummies - showed neck loads that were off the charts. Loads that would kill.\n> \n> This data drove everything that came next.\n\n---\n\n## SLIDE 7: The Engineering Response\n**Visual:** Diagram of multi-stage airbag system  \n**Bullet points:** Depowered bags, dual-stage inflators, occupant classification, suppression systems\n\n### Speaker Notes:\n> The engineering response was comprehensive:\n> \n> First, immediate depowering - reducing inflation force by 20-35%. This happened in 1998.\n> \n> Then, dual-stage inflators that could vary deployment force based on crash severity.\n> \n> Then, occupant classification systems - weight sensors in seats that detect if a child or small adult is present.\n> \n> Then, suppression systems that turn off the airbag entirely for rear-facing child seats.\n> \n> Every single one of these solutions required new testing. New test protocols. New instrumentation. New data channels.\n> \n> *[Pause]*\n> \n> And it worked. Airbag-related fatalities dropped from over 50 per year to near zero.\n\n---\n\n## SLIDE 8: The DTS Connection\n**Visual:** Photo of CRABI infant dummy or small female dummy with DTS instrumentation  \n**Caption:** DTS accelerometers in out-of-position testing\n\n### Speaker Notes:\n> Where does DTS fit in?\n> \n> Out-of-position testing requires precise measurements in very small packages. The forces on a child dummy's neck. The acceleration of an infant's head. The chest deflection of a 5th percentile female.\n> \n> These measurements need to be accurate, repeatable, and small enough to fit in small dummies without affecting their biofidelity.\n> \n> That's what we do. Our accelerometers are in the CRABI infant dummy. Our data acquisition systems capture the millisecond-by-millisecond record of what happens when an airbag meets an out-of-position occupant.\n> \n> Without that data, there's no depowering. There's no dual-stage inflator. There's no occupant classification. And there are more dead children.\n\n---\n\n## SLIDE 9: Story 2 - The Luxury Car That Failed\n**Visual:** IIHS Small Overlap test photo - crumpled luxury vehicle  \n**Subtitle:** The 2012 Small Overlap Shock\n\n### Speaker Notes:\n> Let's move to story two. This one might surprise you.\n> \n> 2012. The Insurance Institute for Highway Safety introduces a new test: the small overlap frontal crash. Twenty-five percent overlap, rigid barrier, 40 miles per hour.\n> \n> The industry assumed their vehicles would do fine. After all, they'd been acing the moderate overlap test for years. Mercedes, BMW, Audi - surely they'd pass.\n> \n> *[Pause]*\n> \n> They didn't.\n\n---\n\n## SLIDE 10: The Results\n**Visual:** Table showing 2012 small overlap results  \n- BMW 5-Series: Marginal\n- Mercedes C-Class: Marginal\n- Audi A4: Marginal\n- Lexus ES: Poor\n\n### Speaker Notes:\n> Look at this list. BMW 5-Series - Marginal. Mercedes C-Class - Marginal. Audi A4 - Marginal. Lexus ES - Poor.\n> \n> These are some of the most expensive, most prestigious vehicles on the road. And they failed a crash test.\n> \n> Only 3 of 13 midsize cars earned \"Good\" in the first round of testing.\n> \n> This was a wake-up call for the entire industry.\n\n---\n\n## SLIDE 11: What the Data Showed\n**Visual:** Comparison - good structure vs. poor structure (intrusion data)  \n**Annotation:** Firewall intrusion, footwell collapse, steering column displacement\n\n### Speaker Notes:\n> What did the data show?\n> \n> *[Point to comparison]*\n> \n> On the left: a vehicle with good small overlap performance. The crash structure engages, absorbs energy, and the occupant compartment stays intact.\n> \n> On the right: a vehicle that failed. See how the structure bypasses the main longitudinal rails? The wheel gets pushed back. The firewall collapses. The footwell crushes. The steering column displaces into the occupant.\n> \n> The dummies - instrumented with accelerometers and load cells - told the story. Head injury numbers through the roof. Leg loads exceeding injury thresholds. Feet trapped in crushed footwells.\n> \n> This wasn't visible from looking at the car. You had to see the data.\n\n---\n\n## SLIDE 12: The Industry Response\n**Visual:** Before/after structural diagrams showing redesigned front end  \n**Caption:** Structural redesigns across the industry\n\n### Speaker Notes:\n> The industry response was massive. And fast.\n> \n> Within two years, automakers fundamentally redesigned their front structures. They added small overlap-specific load paths. They extended the bumper beam. They reinforced the A-pillar. They changed the wheel well geometry.\n> \n> By 2015, most vehicles were earning \"Good\" ratings. But it required a complete rethink of frontal crash structure.\n> \n> And every one of those redesigned vehicles was validated with crash testing. With instrumented dummies. With data channels.\n\n---\n\n## SLIDE 13: Story 3 - The Sport That Was Killing Its Players\n**Visual:** Vintage football photo - leather helmets  \n**Subtitle:** Football's Deadly Secret\n\n### Speaker Notes:\n> Let's step outside automotive for our third story.\n> \n> In the 1960s and early 1970s, American football was killing its players. Not occasionally - regularly. An average of 32 players died each year from head and neck injuries.\n> \n> Thirty-two funerals. Every year. High school kids. College students. Professional athletes. All dead from a sport.\n> \n> Helmets existed. They just didn't work.\n\n---\n\n## SLIDE 14: The NOCSAE Solution\n**Visual:** Drop tower test equipment  \n**Caption:** NOCSAE drop test - the standard that changed everything\n\n### Speaker Notes:\n> In 1969, the National Operating Committee on Standards for Athletic Equipment - NOCSAE - was formed. Their mission: create a helmet standard that would actually prevent deaths.\n> \n> They developed the drop test. A helmeted headform dropped from 60 inches onto various anvils. The headform instrumented with accelerometers.\n> \n> The metric they chose: Severity Index. An integral of acceleration over time, raised to the 2.5 power. If SI exceeded 1200, the helmet failed.\n> \n> It was simple. It was repeatable. And it worked.\n\n---\n\n## SLIDE 15: The Results\n**Visual:** Graph showing football fatalities before and after NOCSAE  \n- 1970: ~32 deaths/year\n- 1980: ~8 deaths/year\n- 2020: ~3 deaths/year\n\n### Speaker Notes:\n> *[Point to graph]*\n> \n> Look at this curve.\n> \n> Pre-NOCSAE: 32 deaths per year.\n> \n> After the standard was mandated in 1980: deaths dropped to single digits.\n> \n> Today: typically 3 or fewer deaths per year from head/neck trauma in football.\n> \n> That's a 90% reduction. Not from rule changes. Not from better coaching. From better helmets - helmets validated with instrumented testing.\n\n---\n\n## SLIDE 16: The DTS Connection\n**Visual:** Linear impactor test setup / helmet testing equipment  \n**Caption:** Modern helmet testing - now including rotational metrics\n\n### Speaker Notes:\n> DTS instrumentation is used in helmet testing facilities around the world.\n> \n> Our accelerometers are in the headforms. Our data acquisition systems capture the impact data. Our calibration standards ensure that a test run in Kansas gives the same result as a test run in Virginia.\n> \n> And the science keeps advancing. The original drop test measured linear acceleration. Today, we're adding rotational acceleration - because we now understand that concussions are caused by brain rotation, not just linear impact.\n> \n> That means new sensors. New data channels. New measurement techniques. The same DTS capabilities that serve automotive are now serving sports safety.\n\n---\n\n## SLIDE 17: Part 2 - Surprising Applications\n**Visual:** Section divider  \n**Title:** PART 2: Customers You Didn't Know You Had\n\n### Speaker Notes:\n> Those three stories - airbags, small overlap, football helmets - are the obvious ones. Automotive and sports. The things you'd expect.\n> \n> But DTS equipment shows up in places you might not expect. Let me give you a quick tour of some surprising applications.\n\n---\n\n## SLIDE 18: Military - The WIAMan Dummy\n**Visual:** WIAMan dummy in military vehicle  \n**Caption:** Protecting soldiers from IED underbody blast\n\n### Speaker Notes:\n> The military has a problem. IEDs - improvised explosive devices - are killing soldiers by sending blast forces up through vehicle floors.\n> \n> Traditional crash test dummies weren't designed for this. They measure horizontal impact, not vertical blast.\n> \n> So the Army developed WIAMan - the Warrior Injury Assessment Manikin. A dummy specifically designed for underbody blast assessment.\n> \n> *[Pause]*\n> \n> DTS was a key partner in developing WIAMan's instrumentation. Our accelerometers measure the lumbar spine loads that determine whether a soldier's back is broken. Our data acquisition systems capture the blast event.\n> \n> This isn't automotive. But it's the same mission: use data to save lives.\n\n---\n\n## SLIDE 19: Space - Astronaut Protection\n**Visual:** Space capsule splashdown or astronaut seat testing  \n**Caption:** Crew return vehicle impact testing\n\n### Speaker Notes:\n> When a space capsule returns to Earth, it hits the water - or land - hard. Potentially 15g or more of deceleration.\n> \n> How do you know if the astronauts will survive? You test. With instrumented dummies. With accelerometers. With data acquisition systems.\n> \n> DTS equipment has been used to validate crew seating in multiple space programs. The same measurement principles that protect car occupants protect astronauts returning from orbit.\n\n---\n\n## SLIDE 20: Theme Parks - Roller Coaster Safety\n**Visual:** Roller coaster or theme park ride  \n**Caption:** Acceleration limits for amusement rides\n\n### Speaker Notes:\n> Here's one you might not expect: theme parks.\n> \n> Roller coasters are designed to create excitement through acceleration. But there are limits - exceed them, and you injure guests.\n> \n> ASTM standards specify acceleration limits for amusement rides. And how do you verify that a new roller coaster meets those limits? You instrument it. You measure the g-forces. You capture the data.\n> \n> Some theme parks use DTS equipment for this. Same accelerometers. Same data acquisition. Different application.\n\n---\n\n## SLIDE 21: Medical Devices - Implant Testing\n**Visual:** Medical device impact testing or spinal implant  \n**Caption:** Validating devices that go inside human bodies\n\n### Speaker Notes:\n> Medical devices like spinal implants or joint replacements experience repeated loading inside the body. Drop something? An impact load.\n> \n> Device manufacturers need to know: will this implant survive real-world conditions?\n> \n> Impact testing of medical devices uses the same principles as crash testing. Controlled impacts. Measured forces. Data analysis. Some of that testing uses DTS equipment.\n\n---\n\n## SLIDE 22: The Common Thread\n**Visual:** Graphic showing diverse applications connected to \"PRECISE MEASUREMENT\"  \n**Caption:** Different industries. Same mission.\n\n### Speaker Notes:\n> Automotive. Sports. Military. Space. Theme parks. Medical devices.\n> \n> What do they all have in common?\n> \n> They all need precise measurement of dynamic events. Events that happen in milliseconds. Events that determine whether someone lives or dies, walks or doesn't, returns from space or doesn't.\n> \n> That's what DTS does. We provide the measurement capability that enables safety engineering across all these fields.\n\n---\n\n## SLIDE 23: Part 3 - Engineering Impact\n**Visual:** Section divider  \n**Title:** PART 3: Good Data Enables Good Decisions\n\n### Speaker Notes:\n> Let me shift gears and talk directly to the engineers in the room.\n> \n> Everything I've shown you - the airbag fixes, the structural redesigns, the helmet improvements - all of it depends on one thing: good data.\n> \n> Bad data leads to bad decisions. And in safety engineering, bad decisions cost lives.\n> \n> Let me show you what I mean.\n\n---\n\n## SLIDE 24: What Good Data Looks Like\n**Visual:** Clean data trace with proper characteristics  \n**Annotations:** Pre-trigger baseline, appropriate filter, clear signal, no saturation\n\n### Speaker Notes:\n> Here's what good data looks like.\n> \n> *[Point to features]*\n> \n> Clean pre-trigger baseline - the sensor was working before the event.\n> \n> Appropriate filtering - CFC 1000 for head acceleration, removing noise without distorting the signal.\n> \n> Clear signal - you can see exactly what happened, when it happened.\n> \n> No saturation - the sensor range was appropriate for the event.\n> \n> This is data you can trust. Data that can drive engineering decisions.\n\n---\n\n## SLIDE 25: What Bad Data Looks Like\n**Visual:** Problematic data traces  \n**Examples:** Saturated signal, excessive noise, zero shift, cable artifact\n\n### Speaker Notes:\n> And here's what bad data looks like.\n> \n> *[Point to examples]*\n> \n> Saturated signal - the accelerometer was overranged. We don't know what the actual peak was. Could have been 100g. Could have been 500g. We don't know.\n> \n> Excessive noise - either electrical interference or mechanical resonance. The real signal is buried in garbage.\n> \n> Zero shift - the sensor's baseline moved after impact. Every measurement after this point is wrong.\n> \n> Cable artifact - that spike isn't acceleration, it's the cable being yanked.\n> \n> *[Pause]*\n> \n> You cannot make good engineering decisions with bad data. If a customer makes a vehicle safer based on bad data, they might be making it more dangerous.\n\n---\n\n## SLIDE 26: Why This Matters for Your Work\n**Visual:** Product development cycle with \"DATA QUALITY\" highlighted  \n**Caption:** Your decisions affect every test run with our equipment\n\n### Speaker Notes:\n> Here's why this matters for everyone in this room.\n> \n> Every design decision you make - sensor selection, cable design, data acquisition architecture, software algorithms, calibration procedures - affects the quality of data our customers collect.\n> \n> When you choose a sensor range, you're deciding whether customers will saturate.\n> \n> When you design a mounting system, you're determining whether they'll get resonance artifacts.\n> \n> When you write calibration procedures, you're setting the accuracy baseline for every test.\n> \n> These aren't abstract technical decisions. They're decisions that determine whether an engineer at GM or Toyota or BMW can trust the data. And trust the conclusions they draw from it.\n\n---\n\n## SLIDE 27: The Ripple Effect\n**Visual:** Diagram showing DTS product → Customer test → Vehicle design → Road safety  \n**Caption:** Your work affects millions\n\n### Speaker Notes:\n> Let me paint the picture.\n> \n> You design a product. That product goes to a customer. The customer runs a test. The test generates data. That data influences a design decision. That design goes into a vehicle. That vehicle is manufactured a million times. Those million vehicles protect millions of occupants.\n> \n> The ripple effect of your work is enormous. You might never see it. You might never know about it. But it's there.\n> \n> Every calibration. Every design review. Every manufacturing check. They all matter.\n\n---\n\n## SLIDE 28: Closing - The Human Element\n**Visual:** Section divider  \n**Title:** CLOSING: Remember the Why\n\n### Speaker Notes:\n> I want to close by bringing us back to the human element.\n> \n> It's easy to get lost in specifications. Sample rates. Filter classes. Calibration tolerances. These things matter - I've just told you why they matter.\n> \n> But let's not forget why we care about those specifications.\n\n---\n\n## SLIDE 29: The Real Customers\n**Visual:** Collage of real people - families, children, commuters  \n**Caption:** These are the people we protect\n\n### Speaker Notes:\n> These are our real customers.\n> \n> Not the test lab. Not the automotive OEM. Not the government regulator.\n> \n> The real customers are the people who will sit in the vehicles that get designed using our data. The children who ride in car seats validated with our instrumentation. The soldiers protected by armor tested with our equipment. The athletes wearing helmets certified with our measurement systems.\n> \n> They don't know our name. They don't know what DTS is. But their lives depend on us doing our jobs well.\n\n---\n\n## SLIDE 30: The Work Isn't Done\n**Visual:** Emerging challenges - EVs, autonomous vehicles, pedestrian safety  \n**Caption:** New challenges require new solutions\n\n### Speaker Notes:\n> And the work isn't done.\n> \n> Electric vehicles have different crash characteristics - battery integrity, high-voltage safety.\n> \n> Autonomous vehicles need validation of active safety systems in ways we're still figuring out.\n> \n> Pedestrian and cyclist fatalities are rising even as occupant fatalities fall - new protection challenges.\n> \n> Military threats evolve constantly.\n> \n> Sports science is discovering new mechanisms of brain injury.\n> \n> Every one of these challenges will require new testing. New instrumentation. New data. New solutions from companies like DTS.\n\n---\n\n## SLIDE 31: Final Thought\n**Visual:** Simple text on dark background  \n**Quote:** \"Every channel of data tells a story. Make sure it's accurate enough to save a life.\"\n\n### Speaker Notes:\n> I'll leave you with this.\n> \n> Every channel of data tells a story. A story about what happened in a crash test. A story about forces and accelerations and human tolerance. A story that will be read by engineers making decisions about vehicle design.\n> \n> Make sure those stories are accurate. Make sure they're reliable. Make sure they're precise.\n> \n> Because somewhere, someday, a vehicle designed using data from our equipment will be in a crash. And the person inside will either walk away or they won't.\n> \n> That's the story our data tells. Let's make sure we're telling it right.\n> \n> Thank you.\n\n---\n\n## SLIDE 32: Questions\n**Visual:** \"Questions?\" with contact information  \n**Caption:** Ben [Last Name], Application Engineer\n\n### Speaker Notes:\n> I'm happy to take questions. And if you want to hear more stories from the field - the weird tests, the challenging customers, the equipment that survived things it shouldn't have - come find me. I've got plenty more.\n> \n> *[Open for Q&A]*\n\n---\n\n# APPENDIX: ADDITIONAL TALKING POINTS\n\n## If Asked About Specific Products\n- Reference SLICE systems for in-dummy acquisition\n- Mention TDAS for vehicle-level data\n- Discuss calibration services and traceability\n\n## If Asked About Competition\n- Focus on DTS advantages: reliability, size, support\n- Don't disparage competitors - redirect to customer mission\n\n## If Asked About Future Technology\n- Discuss emerging measurement needs (rotational brain injury, EV testing)\n- Mention R&D initiatives if appropriate\n- Emphasize continuous improvement\n\n## Backup Stories (if time permits)\n1. The test where the camera caught fire but DTS equipment kept recording\n2. The customer who found a design flaw 2 weeks before production\n3. The dummy that was dropped (accidentally) and the data that was recovered\n\n---\n\n# TIMING GUIDE\n\n| Section | Duration | Cumulative |\n|---------|----------|------------|\n| Opening (Slides 1-3) | 5 min | 5 min |\n| Part 1 - Headlines (Slides 4-16) | 15 min | 20 min |\n| Part 2 - Surprising Applications (Slides 17-22) | 8 min | 28 min |\n| Part 3 - Engineering Impact (Slides 23-27) | 10 min | 38 min |\n| Closing (Slides 28-32) | 5 min | 43 min |\n| Q&A Buffer | 2 min | 45 min |\n\n---\n\n# EQUIPMENT/MATERIALS NEEDED\n\n1.

Every safety standard was written in blood\n2. Data is the bridge between tragedy and solution\n3. DTS equipment is the instrument that captures that bridge\n4. Our work has profound human meaning\n\n**Emotional Arc:** \n- Open with tragedy (create emotional investment)\n- Build through investigation and data\n- Resolve with triumph (engineering solution + lives saved)\n- Repeat pattern 3-4 times, building cumulative impact\n\n---\n\n# SLIDE-BY-SLIDE SCRIPT AND SPEAKER NOTES\n\n---\n\n## SLIDE 1: Title Slide\n**Visual:** Dark background with subtle gradient  \n**Title:** From Tragedy to Triumph  \n**Subtitle:** How Data Transformed Deaths into Design Changes\n\n### Speaker Notes:\n> *[Start with silence. Let the room settle.]*\n> \n> Every safety standard was written in blood.\n> \n> That's not a metaphor. It's literal truth. Behind every FMVSS regulation, every IIHS test protocol, every NOCSAE helmet standard - there are people who died.\n> \n> Today I want to tell you four stories. Four tragedies that became triumphs. Four times when data - data captured by instrumentation like ours - made the difference between \"people keep dying\" and \"this never happens again.\"\n> \n> These stories are not easy to hear. But I think they're important. Because they remind us why we do what we do.\n\n---\n\n## SLIDE 2: Story Structure\n**Visual:** Simple diagram showing the arc  \n**Path:** Tragedy → Investigation → Data → Solution → Triumph\n\n### Speaker Notes:\n> Every story I'm going to tell follows the same arc.\n> \n> It starts with tragedy. Someone dies. Often many people die.\n> \n> Then comes investigation. Engineers ask: What happened? Why?\n> \n> Then data. We test. We measure. We quantify what went wrong.\n> \n> Then solution. We redesign. We regulate. We change.\n> \n> And finally, triumph. The deaths stop. Lives are saved.\n> \n> This arc - from tragedy to triumph - is the arc of safety engineering. And data is the hinge point that makes the transformation possible.\n\n---\n\n## SLIDE 3: Story 1 Introduction\n**Visual:** Section divider  \n**Title:** STORY 1: The Children Who Were Killed by Safety\n\n### Speaker Notes:\n> Story one. The children who were killed by safety.\n> \n> This is perhaps the most tragic story in automotive safety history. Because the very device designed to protect - the airbag - became the killer.\n\n---\n\n## SLIDE 4: The Tragedy - A Name\n**Visual:** Simple memorial-style slide  \n**Text:** \"In memory of the 175+ people killed by airbags, 1990-1997\"  \n**Below:** \"Many were children sitting in the front seat\"\n\n### Speaker Notes:\n> Between 1990 and 1997, airbags killed over 175 people.\n> \n> Most of them were children. Some were small women. Some were people who sat too close to the steering wheel.\n> \n> *[Pause - let this land]*\n> \n> The youngest victim I know of was 1 month old. Killed by an airbag while riding in a rear-facing car seat placed in the front passenger position.\n> \n> These weren't high-speed crashes. These were fender-benders. 10 mph impacts. Situations where everyone should have walked away.\n> \n> Instead, parents watched their children die from the very device that was supposed to protect them.\n\n---\n\n## SLIDE 5: The Question\n**Visual:** Large question mark  \n**Text:** \"Why were airbags killing the people they were designed to protect?\"\n\n### Speaker Notes:\n> The question was devastating: Why?\n> \n> Airbags had been sold as the ultimate safety device. They would save 12,000 lives per year, the government said. And they were saving lives - adult male lives, mostly.\n> \n> But they were also killing. And the deaths were concentrated among a specific population: Children. Small women. Anyone who wasn't a large adult male.\n> \n> Engineers had to find out why. And the only way to find out was to test.\n\n---\n\n## SLIDE 6: The Investigation\n**Visual:** Photo of out-of-position testing setup or small dummy  \n**Caption:** Out-of-position testing with child and small female dummies\n\n### Speaker Notes:\n> The investigation centered on out-of-position testing.\n> \n> What happens when someone isn't sitting in the ideal position? What happens when they're too close to the airbag? What happens when they're small?\n> \n> Researchers put instrumented dummies - small female dummies, child dummies, infant dummies - in various positions relative to the airbag. And then they deployed the airbag.\n> \n> The dummies were instrumented with accelerometers and load cells. The same kinds of sensors DTS makes today.\n\n---\n\n## SLIDE 7: The Data\n**Visual:** Illustration of data showing neck loads  \n**Annotations:** \"Peak neck tension: 3,500 N\" / \"Injury threshold: 1,600 N\"\n\n### Speaker Notes:\n> The data was horrifying.\n> \n> Early airbags inflated at roughly 200 miles per hour. When that explosion hit a small child positioned close to the bag, the neck loads were catastrophic.\n> \n> The injury threshold for a child's neck is about 1,600 Newtons. The data showed loads of 3,500 Newtons or more. More than double the fatal threshold.\n> \n> The airbags weren't just dangerous - they were essentially guaranteed to kill children in certain positions.\n> \n> But without the data, no one would have known exactly why. And without knowing why, you can't engineer a solution.\n\n---\n\n## SLIDE 8: The Solution\n**Visual:** Diagram showing multi-stage airbag system components  \n**Bullets:** Depowered bags, dual-stage, occupant classification, suppression\n\n### Speaker Notes:\n> The data drove a cascade of engineering solutions:\n> \n> First, in 1998, immediate depowering. Reduce the inflation force by 20-35%. Accept that some large males in severe crashes might not be perfectly protected, in exchange for not killing children.\n> \n> Second, dual-stage inflators. Variable deployment force based on crash severity. Light crash? Light deployment.\n> \n> Third, occupant classification. Weight sensors in seats to detect children and small adults. Adjust or suppress the airbag accordingly.\n> \n> Fourth, suppression for rear-facing child seats. If a sensor detects a rear-facing seat, the airbag turns off completely.\n> \n> Each of these solutions required new testing. New data. New validation that the fix actually worked.\n\n---\n\n## SLIDE 9: The Triumph\n**Visual:** Graph showing airbag fatalities declining  \n**Data:** From 50+/year (1997) to near zero (2020s)\n\n### Speaker Notes:\n> The triumph: Airbag fatalities dropped from over 50 per year to essentially zero.\n> \n> Modern airbags are smart. They detect who's in the seat. They know how severe the crash is. They deploy with appropriate force - or don't deploy at all.\n> \n> And those 50+ people per year who used to die? They're alive. Every year, those 50 people go home to their families instead of going to the morgue.\n> \n> That's what data did. Data turned a child-killing device into a life-saving device.\n\n---\n\n## SLIDE 10: Story 2 Introduction\n**Visual:** Section divider  \n**Title:** STORY 2: The Car That Was Cheaper to Let Burn\n\n### Speaker Notes:\n> Story two. The car that was cheaper to let burn.\n> \n> This is the story of the Ford Pinto. And it's a story about what happens when engineering is overruled by accounting.\n\n---\n\n## SLIDE 11: The Tragedy\n**Visual:** Newspaper headlines about Pinto fires  \n**Headlines:** \"Pinto Fire Kills Mother and Child\" / \"Exploding Gas Tanks - Who Knew?\"\n\n### Speaker Notes:\n> The Ford Pinto was a bestseller in the 1970s. Small, cheap, fuel-efficient during the oil crisis.\n> \n> It had one problem: The gas tank was mounted behind the rear axle, only 9 inches from the rear bumper.\n> \n> In a rear-end collision - even at moderate speed - the rear crumpled into the gas tank. The tank ruptured. Fuel sprayed. A spark ignited it.\n> \n> And people burned to death inside their cars.\n> \n> It's impossible to know the exact death toll. Estimates range from 27 to several hundred. What we know for certain: Ford knew about the problem before anyone died.\n\n---\n\n## SLIDE 12: The Investigation - The Memo\n**Visual:** Quote from the infamous Ford memo  \n**Quote:** \"Costs: $11 per car × 12.5 million cars = $137 million\"  \n**Quote:** \"Benefits: 180 deaths × $200,000 = $36 million\"  \n**Caption:** Internal Ford cost-benefit analysis\n\n### Speaker Notes:\n> *[Let the audience read the slide]*\n> \n> This is from an actual internal Ford memo.\n> \n> The cost to fix the problem: $11 per car. Eleven dollars. For 12.5 million vehicles, that's $137 million.\n> \n> The \"benefit\" of fixing it - in Ford's calculation - was 180 fewer deaths. At $200,000 per death (their number), that's $36 million.\n> \n> Cost exceeds benefit. Don't fix it.\n> \n> *[Pause]*\n> \n> This is what happens when safety decisions are made without proper data context. When human lives are just numbers in a spreadsheet.\n\n---\n\n## SLIDE 13: The Data\n**Visual:** Illustration of rear impact test data  \n**Annotations:** Fuel leakage measurements, fire risk metrics\n\n### Speaker Notes:\n> The data that should have driven the decision was clear.\n> \n> Rear impact testing showed fuel leakage far exceeding safe limits. The tank design failed at impacts as low as 25 mph.\n> \n> Ford's own engineers knew. They had the data. But the data didn't make it past the accounting department.\n> \n> After the scandal broke, after the lawsuits, after the criminal charges - the federal government strengthened FMVSS 301, the fuel system integrity standard.\n> \n> Now every vehicle is tested. Rear impact at 50 mph. Side impact at 20 mph. Rollover in 360 degrees. Fuel leakage is measured precisely - using instrumentation - and limits are enforced.\n\n---\n\n## SLIDE 14: The Solution\n**Visual:** Modern fuel system protection features  \n**Bullets:** Reinforced tanks, shields, self-sealing lines, protected locations\n\n### Speaker Notes:\n> The solutions were straightforward - and cheap.\n> \n> That $11 fix? It included a plastic shield to protect the tank, reinforced bumper mounts, and better tank location.\n> \n> Today, fuel system integrity is non-negotiable. Tanks are mounted in protected locations. They're designed to deform without rupturing. Fuel lines are self-sealing.\n> \n> And critically: Every design is tested. Instrumented. Measured. You can't claim safety without proving it with data.\n\n---\n\n## SLIDE 15: The Triumph\n**Visual:** Statistics on fire deaths  \n**Text:** \"Vehicle fire deaths: Down 76% since 1980\"\n\n### Speaker Notes:\n> The triumph: Vehicle fire deaths have dropped 76% since 1980.\n> \n> Some of that is better firefighting. Some is better rescue. But much of it is engineering: Vehicles simply don't catch fire like they used to.\n> \n> The Pinto scandal forced the industry to take fuel system safety seriously. It forced regulators to mandate testing. And it established the principle that safety decisions must be based on data, not cost-benefit analysis.\n\n---\n\n## SLIDE 16: Story 3 Introduction\n**Visual:** Section divider  \n**Title:** STORY 3: The Test That Humbled an Industry\n\n### Speaker Notes:\n> Story three. The test that humbled an industry.\n> \n> This is the story of the IIHS small overlap test. And it's a reminder that even when we think we've solved a problem, we might be missing something.\n\n---\n\n## SLIDE 17: The Tragedy Pattern\n**Visual:** Crash reconstruction showing small overlap impact  \n**Caption:** The crash pattern that kept killing people\n\n### Speaker Notes:\n> By 2010, frontal crash safety was considered a solved problem. Vehicles were acing the federal full-frontal test. They were acing the IIHS moderate overlap test. Deaths were down.\n> \n> But IIHS researchers noticed something in real-world crash data. People were still dying in frontal crashes. And they were dying in a specific pattern.\n> \n> Tree strikes. Pole strikes. Corner-to-corner with other vehicles. Crashes where only 20-25% of the vehicle's width was engaged.\n> \n> These \"small overlap\" crashes weren't captured by existing tests. The vehicles that aced the 40% overlap test? They were failing in real crashes.\n\n---\n\n## SLIDE 18: The Investigation\n**Visual:** Photo of IIHS small overlap test in progress  \n**Caption:** 25% overlap, rigid barrier, 40 mph\n\n### Speaker Notes:\n> IIHS developed a new test. Twenty-five percent overlap. Rigid barrier - not deformable. Forty miles per hour.\n> \n> The test was designed to stress the part of the vehicle structure that existing tests missed: The outer edge. The corner. The area where all those trees and poles were hitting.\n> \n> In 2012, they started testing. The results shocked everyone.\n\n---\n\n## SLIDE 19: The Data - The Failure\n**Visual:** Test results table  \n**Show:** BMW, Mercedes, Audi, Lexus - all Marginal or Poor\n\n### Speaker Notes:\n> BMW 5-Series: Marginal.\n> Mercedes C-Class: Marginal.\n> Audi A4: Marginal.\n> Lexus ES: Poor.\n> \n> These are the most expensive, most prestigious vehicles on the road. Vehicles marketed as \"safe.\" Vehicles that aced every other crash test.\n> \n> And they failed. Only 3 of 13 midsize cars earned \"Good\" in the first round.\n> \n> The data showed catastrophic intrusion. Footwells collapsed. Steering columns displaced. Dummies' heads struck hard interior surfaces. Feet were trapped in crushed metal.\n> \n> The instrument data told the story: HIC values exceeding limits. Femur loads off the charts. Lower leg compression in the critical injury range.\n\n---\n\n## SLIDE 20: The Solution\n**Visual:** Before/after structural diagrams  \n**Caption:** Industry redesign of front structures\n\n### Speaker Notes:\n> The industry responded with remarkable speed.\n> \n> Within two years, most manufacturers had fundamentally redesigned their front structures. They added small overlap load paths. Extended bumper beams. Reinforced A-pillars.\n> \n> By 2015, most vehicles were earning \"Good\" ratings. The test that humbled the industry became the test that improved the industry.\n> \n> But it took instrumented testing to prove the problem. Without precise measurement of what was happening to the dummies - the head injury values, the leg loads, the chest compression - you couldn't quantify the failure. And you couldn't prove that the redesign worked.\n\n---\n\n## SLIDE 21: The Triumph\n**Visual:** Statistics on frontal crash deaths  \n**Text:** \"Frontal crash deaths: Down 8% within 3 years of test introduction\"\n\n### Speaker Notes:\n> The triumph: Within three years of the small overlap test introduction, frontal crash deaths dropped an additional 8%.\n> \n> That's after decades of improvement. That's when everyone thought frontal safety was \"done.\"\n> \n> The test revealed a hidden vulnerability. Data quantified it. Engineering fixed it. And real people - thousands of them - are alive because of it.\n\n---\n\n## SLIDE 22: Story 4 Introduction\n**Visual:** Section divider  \n**Title:** STORY 4: The Sport That Saved Itself\n\n### Speaker Notes:\n> Story four. The sport that saved itself.\n> \n> This is the story of football helmets. And it's a reminder that safety standards can transform an entire culture.\n\n---\n\n## SLIDE 23: The Tragedy\n**Visual:** Vintage football injury photo or memorial  \n**Text:** \"32 players per year, 1960s-1970s\"  \n**Caption:** Killed by head and neck injuries in football\n\n### Speaker Notes:\n> In the 1960s and early 1970s, American football was deadly.\n> \n> Thirty-two players died every year from head and neck injuries. High school kids. College students. Professionals.\n> \n> Helmets existed. Players wore them. But the helmets weren't protecting them - because there was no standard. There was no test. There was no way to know if a helmet actually worked.\n> \n> Manufacturers made claims. Coaches trusted them. And players died.\n\n---\n\n## SLIDE 24: The Investigation\n**Visual:** Photo of drop tower testing  \n**Caption:** NOCSAE drop test development, 1970s\n\n### Speaker Notes:\n> In 1969, the National Operating Committee on Standards for Athletic Equipment - NOCSAE - was formed.\n> \n> Their mission: Develop a test that actually predicts whether a helmet will protect a player.\n> \n> They built drop towers. They instrumented headforms with accelerometers. They developed the Severity Index metric - an integral of acceleration that correlates with brain injury risk.\n> \n> They tested every helmet on the market. Many failed. Some failed spectacularly.\n\n---\n\n## SLIDE 25: The Data\n**Visual:** Chart showing SI values for different helmets  \n**Annotations:** Pass/fail threshold at SI 1200\n\n### Speaker Notes:\n> The data was stark.\n> \n> Some helmets attenuated impact beautifully - SI values of 600, 800. Well under the 1200 threshold.\n> \n> Other helmets - including some market leaders - showed SI values of 1500, 1800, 2000. They weren't just failing; they weren't even close to passing.\n> \n> Players were wearing helmets that provided almost no protection. And nobody knew - because nobody had measured.\n> \n> NOCSAE measurement changed that. Suddenly there was objective data. Helmets either worked or they didn't. And you could prove which was which.\n\n---\n\n## SLIDE 26: The Solution\n**Visual:** Modern football helmet design features  \n**Bullets:** Energy-absorbing liners, improved shells, standardized testing\n\n### Speaker Notes:\n> The solution was elegant: Set a standard, and let the market respond.\n> \n> NOCSAE established the SI < 1200 requirement. In 1980, the NCAA mandated that all helmets meet the standard. High school federations followed.\n> \n> Suddenly, helmet manufacturers had to design for performance, not just appearance. Helmets got better liners. Better shells. Better overall performance.\n> \n> And the standard kept evolving. In 2016, NOCSAE added the linear impactor test for rotational injury assessment. The science advances; the standard advances.\n\n---\n\n## SLIDE 27: The Triumph\n**Visual:** Graph showing football fatalities over time  \n**Data:** 32/year (1970) → 8/year (1985) → 3/year (2020)\n\n### Speaker Notes:\n> The triumph: Football deaths from head and neck injuries dropped by over 90%.\n> \n> From 32 per year to typically 3 or fewer. Hundreds of lives saved every year.\n> \n> That's not better coaching. That's not rule changes. That's engineering. Helmets validated with instrumented testing. Helmets that actually work.\n> \n> And DTS instrumentation is in testing labs around the country, validating helmets every day. The same measurement principles that started this revolution continue to drive it forward.\n\n---\n\n## SLIDE 28: The Pattern\n**Visual:** Four arcs showing all four stories  \n**Summary:** Tragedy → Data → Solution → Triumph (×4)\n\n### Speaker Notes:\n> Four stories. Four tragedies. Four triumphs.\n> \n> Children killed by airbags → Out-of-position testing data → Smart airbags → Deaths to zero.\n> \n> People burning in Pintos → Fuel system testing data → Protected fuel systems → Fire deaths down 76%.\n> \n> Drivers dying in small overlap crashes → New test protocol data → Structural redesign → Frontal deaths down 8%.\n> \n> Football players killed → Helmet testing data → Better helmets → Deaths down 90%.\n> \n> Every one of these transformations ran through the same chokepoint: Data. Instrumented testing. Precise measurement of what was going wrong.\n\n---\n\n## SLIDE 29: Where DTS Fits\n**Visual:** Connection diagram  \n**Center:** DTS Instrumentation  \n**Spokes:** Crash labs, helmet labs, military labs, sports labs\n\n### Speaker Notes:\n> Where does DTS fit in this arc?\n> \n> We're in the middle. We're the data capture mechanism.\n> \n> Our accelerometers are in the dummies. Our data acquisition systems are in the crash labs. Our calibration standards ensure that a measurement in Detroit means the same thing as a measurement in Stuttgart.\n> \n> We don't design the vehicles. We don't write the regulations. We don't do the engineering analysis.\n> \n> But without accurate data capture, none of that other work is possible. We're the foundation that everything else builds on.\n\n---\n\n## SLIDE 30: The Ongoing Mission\n**Visual:** List of current/emerging challenges  \n**Bullets:** EV safety, autonomous vehicles, pedestrian protection, new concussion science\n\n### Speaker Notes:\n> And the mission continues.\n> \n> Electric vehicles are crashing differently. Batteries are bringing new failure modes. We need new instrumentation.\n> \n> Autonomous vehicles need validation of active safety. Not just \"what happens in a crash\" but \"did the vehicle avoid the crash?\" That's new measurement territory.\n> \n> Pedestrian and cyclist deaths are rising even as occupant deaths fall. We need instrumentation for active pedestrian protection systems.\n> \n> Concussion science is revealing that rotational acceleration matters as much as linear. We need sensors that capture rotation.\n> \n> Each of these challenges will follow the same arc. There will be tragedies. There will be investigations. There will be data. And there will be solutions.\n> \n> DTS will be part of that arc - providing the instrumentation that turns tragedy into triumph.\n\n---\n\n## SLIDE 31: Final Reflection\n**Visual:** Simple text on dark background  \n**Quote:** \"Behind every safety standard is someone who didn't come home. Data ensures their loss wasn't in vain.\"\n\n### Speaker Notes:\n> I want to leave you with this thought.\n> \n> Behind every safety standard is someone who didn't come home. A child killed by an airbag. A mother burned in a Pinto. A driver crushed in a small overlap crash. A football player who never got up.\n> \n> Those deaths can't be undone. But data - accurate, reliable, precise data - ensures that their loss wasn't in vain.\n> \n> The data we capture enables the engineering changes that prevent the next death. And the next. And the next.\n> \n> That's what we do. That's why it matters. That's why I'm proud to work here.\n> \n> Thank you.\n\n---\n\n## SLIDE 32: Questions\n**Visual:** \"Questions?\"  \n**Subtitle:** Ben - Application Engineer\n\n### Speaker Notes:\n> I'm happy to take questions. These are heavy stories - if you need a moment to process, that's okay too.\n> \n> *[Open for Q&A]*\n\n---\n\n# APPENDIX: ADDITIONAL STORIES (BACKUP)\n\n## Story: The Roof That Crushed\n- Ford Explorer/Firestone rollover crisis\n- 271 deaths attributed to rollovers\n- FMVSS 216 upgrade from 1.5× to 3× vehicle weight\n- IIHS roof test at 4× for \"Good\"\n\n## Story: The Seat That Whipped\n- Whiplash causing more injury claims than any other type\n- BioRID II dummy development\n- IIHS head restraint ratings\n- Industry response to dynamic testing\n\n## Story: The Truck That Underrode\n- Jayne Mansfield death (1967) driving rear underride awareness\n- FMVSS 223/224 rear impact guards\n- IIHS underride testing\n- Ongoing gaps in side underride protection\n\n---\n\n# TIMING GUIDE\n\n| Section | Duration | Cumulative |\n|---------|----------|------------|\n| Opening (Slides 1-2) | 4 min | 4 min |\n| Story 1 - Airbags (Slides 3-9) | 10 min | 14 min |\n| Story 2 - Pinto (Slides 10-15) | 8 min | 22 min |\n| Story 3 - Small Overlap (Slides 16-21) | 8 min | 30 min |\n| Story 4 - Football (Slides 22-27) | 8 min | 38 min |\n| Closing (Slides 28-32) | 5 min | 43 min |\n| Q&A Buffer | 2 min | 45 min |\n\n---\n\n# EMOTIONAL MANAGEMENT NOTES\n\nThis presentation deals with heavy subject matter. Consider:\n\n1. **Pacing:** Don't rush through the tragedy sections. Let them land.\n2. **Transitions:** Use silence between stories to reset emotional baseline.\n3. **Resolution:** Always end each story on the triumph. Don't leave audience in despair.\n4. **Self-care:** Check in with yourself before presenting. These stories can be draining.\n5. **Audience:** Watch for signs of distress. Have an out if needed.\n\n---\n\n*End of Script and Speaker Notes*\n"

Reality often contradicts expectations\n2. Data reveals what the eye cannot see\n3. Trust the data, not assumptions\n4. This is why rigorous measurement matters\n\n**Tone:** Engaging, interactive, puzzle-like. Audience guessing before reveals.\n\n---\n\n# SLIDE-BY-SLIDE SCRIPT AND SPEAKER NOTES\n\n---\n\n## SLIDE 1: Title Slide\n**Visual:** Question marks and data traces  \n**Title:** When the Data Surprised Us  \n**Subtitle:** Counterintuitive Findings from the Field\n\n### Speaker Notes:\n> Welcome to my favorite presentation to give. This is the one where I get to be a game show host.\n> \n> Over the years in the field, I've seen things that made me say, \"Wait, that can't be right.\" Results that defied expectations. Data that contradicted what everyone assumed.\n> \n> Today I'm going to share some of those stories. And I'm going to make you guess before I reveal the answer.\n> \n> Fair warning: Some of these will mess with your head. That's the point.\n\n---\n\n## SLIDE 2: The Rules of the Game\n**Visual:** Numbered list  \n**Content:**\n1. I'll show you a scenario\n2. You guess what happened\n3. I reveal the data\n4. We discuss why it matters\n\n### Speaker Notes:\n> Here are the rules.\n> \n> I'll show you a scenario. You'll have a few seconds to think about what you expect the data to show.\n> \n> Then I'll reveal what actually happened. Sometimes you'll be right. Often you won't.\n> \n> And then we'll talk about why it matters for the work we do.\n> \n> Ready? Let's go.\n\n---\n\n## SLIDE 3: Puzzle 1 Introduction\n**Visual:** Section divider  \n**Title:** PUZZLE 1: The Beautiful Wreck\n\n### Speaker Notes:\n> Puzzle one. I call this one \"The Beautiful Wreck.\"\n\n---\n\n## SLIDE 4: The Setup - Two Cars\n**Visual:** Two post-crash photos side by side  \n**Car A:** Severely crumpled front end, pushed back, visually destroyed  \n**Car B:** Relatively intact, minimal visible damage\n\n### Speaker Notes:\n> Here are two cars after frontal crash tests. Same test. Same speed. Same barrier.\n> \n> Car A - on the left - is destroyed. The front end is pushed back almost to the firewall. The hood is crumpled like paper. It looks catastrophic.\n> \n> Car B - on the right - looks pretty good. Some crumpling, sure, but the structure held. The passenger compartment looks intact.\n> \n> *[Pause]*\n> \n> Quick poll: Which car do you think had better occupant protection? Which car would you rather be in during a crash?\n> \n> *[Wait for audience response - most will say Car B]*\n\n---\n\n## SLIDE 5: The Reveal\n**Visual:** Data comparison  \n**Car A (destroyed):** HIC 485, Chest 38mm, Femur 4.2 kN - ALL GOOD  \n**Car B (intact):** HIC 890, Chest 58mm, Femur 9.1 kN - MARGINAL/POOR\n\n### Speaker Notes:\n> *[Dramatic pause]*\n> \n> The destroyed car - Car A - had excellent dummy numbers. HIC of 485. Chest deflection of 38 millimeters. Femur load of 4.2 kilonewtons.\n> \n> The intact-looking car - Car B - had terrible dummy numbers. HIC of 890. Chest deflection of 58 millimeters. Femur load just under the injury threshold.\n> \n> *[Let this sink in]*\n> \n> You would rather be in the car that looked destroyed.\n\n---\n\n## SLIDE 6: Why This Happens\n**Visual:** Energy absorption diagram  \n**Caption:** Crush zone is designed to absorb energy - that's the point\n\n### Speaker Notes:\n> Why does this happen?\n> \n> Because crush zones are supposed to crush. That's their job. They absorb energy by deforming. The more they crumple, the more energy they absorb before it reaches the occupant.\n> \n> Car A crumpled beautifully. It extended the deceleration pulse. It gave the occupant more time to slow down. Less force on the body.\n> \n> Car B didn't crumple enough. It was too stiff. The deceleration pulse was short and sharp. The occupant hit a wall of g-forces.\n> \n> Looking at the car tells you nothing about occupant safety. Only the data does.\n\n---\n\n## SLIDE 7: The Lesson\n**Visual:** Quote  \n**Text:** \"Never judge a crash by looking at the car. Judge it by looking at the data.\"\n\n### Speaker Notes:\n> The lesson: Never judge a crash by looking at the car.\n> \n> I've seen this mistake made by journalists writing about crash tests. \"Look how much damage!\" they say. And they conclude the car is unsafe.\n> \n> They've got it backwards. The damage is the safety. The crush zone did its job.\n> \n> This is why we need instrumentation. This is why we need data. Because what you see is not what matters.\n\n---\n\n## SLIDE 8: Puzzle 2 Introduction\n**Visual:** Section divider  \n**Title:** PUZZLE 2: The Survivor's Paradox\n\n### Speaker Notes:\n> Puzzle two. The Survivor's Paradox.\n\n---\n\n## SLIDE 9: The Setup - Rollover Statistics\n**Visual:** Statistics  \n**Text:** \"Rollovers are only 3% of crashes, but account for 33% of fatalities\"\n\n### Speaker Notes:\n> Here's a statistic that drove safety engineers crazy for years.\n> \n> Rollovers are only about 3% of crashes. But they account for roughly a third of fatalities.\n> \n> Obviously, we need stronger roofs, right? Prevent the roof from crushing the occupants during rollover.\n> \n> In 2009, NHTSA doubled the roof crush requirement - from 1.5 times vehicle weight to 3 times vehicle weight.\n> \n> Question: How much did this reduce rollover fatalities?\n\n---\n\n## SLIDE 10: The Reveal\n**Visual:** Graph showing minimal change  \n**Text:** \"Rollover fatalities: Essentially unchanged after roof crush upgrade\"\n\n### Speaker Notes:\n> *[Pause]*\n> \n> Essentially unchanged.\n> \n> Despite doubling the roof strength requirement, rollover fatalities barely moved.\n> \n> *[Wait for reaction]*\n> \n> How is that possible? Wasn't roof crush the problem?\n\n---\n\n## SLIDE 11: The Data Revealed the Real Problem\n**Visual:** Diagram showing ejection during rollover  \n**Text:** \"70%+ of rollover fatalities involve ejection\"\n\n### Speaker Notes:\n> The data revealed the real problem.\n> \n> Over 70% of rollover fatalities involve ejection. The occupant isn't killed by the roof crushing - they're killed by being thrown from the vehicle during the roll.\n> \n> Once you're outside the vehicle, everything is hard. The ground. Other cars. Poles. The vehicle itself rolling over you.\n> \n> Roof crush was a secondary problem. Ejection was the primary problem.\n\n---\n\n## SLIDE 12: The Real Solution\n**Visual:** Side curtain airbag deployment  \n**Text:** \"Side curtain airbags with rollover sensors: 41% reduction in ejection\"\n\n### Speaker Notes:\n> The real solution was side curtain airbags.\n> \n> Airbags that deploy during rollover and stay inflated for 5-6 seconds. Long enough to keep occupants inside the vehicle through multiple rolls.\n> \n> Combined with better seatbelt pretensioners and rollover-sensing systems, ejection rates dropped significantly.\n> \n> The data - ejection statistics, injury mechanisms, survival analysis - pointed to a completely different solution than the intuitive one.\n> \n> Without data, we'd still be making roofs stronger and wondering why people were dying.\n\n---\n\n## SLIDE 13: The Lesson\n**Visual:** Quote  \n**Text:** \"The obvious solution isn't always the right solution. Let the data tell you what's actually happening.\"\n\n### Speaker Notes:\n> The lesson: The obvious solution isn't always the right solution.\n> \n> Everyone assumed roof crush was the killer. The data said ejection was the killer.\n> \n> This happens more than you'd think. The assumed problem isn't the actual problem. And the only way to know is to measure.\n\n---\n\n## SLIDE 14: Puzzle 3 Introduction\n**Visual:** Section divider  \n**Title:** PUZZLE 3: The Luxury Failure\n\n### Speaker Notes:\n> Puzzle three. I mentioned this briefly in another context, but let's really dig into it.\n> \n> The Luxury Failure.\n\n---\n\n## SLIDE 15: The Setup\n**Visual:** Logos of BMW, Mercedes, Audi, Lexus  \n**Text:** \"The most expensive cars. The most prestigious brands. Decades of safety engineering.\"\n\n### Speaker Notes:\n> BMW. Mercedes-Benz. Audi. Lexus.\n> \n> These are the most expensive, most prestigious car brands in the world. They employ thousands of engineers. They've been building cars for decades.\n> \n> They all passed the moderate overlap frontal test with flying colors. Great safety records. Premium pricing partly justified by \"superior safety engineering.\"\n> \n> In 2012, IIHS introduced the small overlap frontal test. Twenty-five percent overlap instead of forty. Rigid barrier instead of deformable.\n> \n> What do you think happened?\n\n---\n\n## SLIDE 16: The Reveal\n**Visual:** Test results with photos  \n**Results:**\n- BMW 5-Series: MARGINAL\n- Mercedes C-Class: MARGINAL\n- Audi A4: MARGINAL\n- Lexus ES 350: POOR\n\n### Speaker Notes:\n> *[Let the slide speak first]*\n> \n> They failed.\n> \n> BMW 5-Series: Marginal.\n> Mercedes C-Class: Marginal.\n> Audi A4: Marginal.\n> Lexus ES 350: Poor.\n> \n> Some of the most expensive vehicles on the road couldn't pass a new crash test.\n\n---\n\n## SLIDE 17: What the Data Showed\n**Visual:** Crash photos showing intrusion  \n**Annotations:** Footwell collapse, steering wheel displacement, head contact with structure\n\n### Speaker Notes:\n> The data told a brutal story.\n> \n> In these vehicles, when the impact was offset to the corner, the crash forces bypassed the main structural rails. The wheel got pushed back into the footwell. The firewall collapsed. The steering column displaced into the occupant.\n> \n> The instrumentated dummy data showed:\n> - Elevated HIC from head striking interior structures\n> - Femur loads near the injury threshold\n> - Lower leg compression in the danger zone\n> - Feet trapped in crushed footwells\n> \n> These vehicles were engineered for the tests that existed. They weren't engineered for this test.\n\n---\n\n## SLIDE 18: The Deeper Lesson\n**Visual:** Text  \n**Quote:** \"Engineering to pass a test is not the same as engineering for safety.\"\n\n### Speaker Notes:\n> Here's the deeper lesson.\n> \n> Engineering to pass a test is not the same as engineering for safety.\n> \n> These automakers had optimized for the 40% overlap test. Their structures were brilliant - for that test. But they'd inadvertently created a vulnerability at the corner.\n> \n> This is why test protocols must evolve. This is why consumer information testing matters. And this is why we need precise data - because without it, you don't know if you've actually solved the problem or just solved one specific scenario.\n\n---\n\n## SLIDE 19: Puzzle 4 Introduction\n**Visual:** Section divider  \n**Title:** PUZZLE 4: The 46.2g Man\n\n### Speaker Notes:\n> Puzzle four. This one goes back to the early days of safety testing.\n> \n> The 46.2g Man.\n\n---\n\n## SLIDE 20: The Setup\n**Visual:** 1950s photo or rocket sled  \n**Text:** \"1954: Conventional wisdom said humans could not survive more than 18g\"\n\n### Speaker Notes:\n> It's 1954. The jet age is dawning. Pilots are flying faster than ever before. And they're dying.\n> \n> Not from crashes - from ejections. Pilots ejecting from aircraft were experiencing massive g-forces. And medical authorities believed that humans could not survive more than 18g of deceleration.\n> \n> If that was true, high-speed ejection was a death sentence. There was no point designing ejection seats for speeds beyond a certain threshold.\n> \n> One researcher decided to test this assumption. Not with dummies. With himself.\n\n---\n\n## SLIDE 21: John Paul Stapp\n**Visual:** Photo of John Paul Stapp  \n**Text:** \"Colonel John Paul Stapp - Air Force flight surgeon\"\n\n### Speaker Notes:\n> Colonel John Paul Stapp. Air Force flight surgeon. And the bravest - or craziest - researcher in the history of safety testing.\n> \n> Stapp strapped himself into a rocket sled. And he ran test after test, pushing higher and higher g-forces.\n\n---\n\n## SLIDE 22: The Reveal\n**Visual:** Data display  \n**Text:** \"December 10, 1954: 46.2g sustained. 632 mph to zero in 1.4 seconds.\"\n\n### Speaker Notes:\n> On December 10, 1954, Stapp rode the rocket sled to 632 miles per hour - faster than a .45 caliber bullet.\n> \n> Then he hit the brakes.\n> \n> In 1.4 seconds, he decelerated from 632 mph to zero. He experienced 46.2g of sustained deceleration.\n> \n> That's more than 2.5 times what \"experts\" said would kill him.\n> \n> He survived. He walked away - temporarily blinded, with burst blood vessels in his eyes, but alive and conscious.\n\n---\n\n## SLIDE 23: What the Data Revealed\n**Visual:** Comparison chart  \n**18g \"limit\" vs. 46.2g survival**\n\n### Speaker Notes:\n> Stapp proved that the human body could survive far more than anyone believed.\n> \n> This data - captured by instrumentation on his sled and his body - revolutionized aviation safety. It meant ejection seats could be designed for higher speeds. It meant survival was possible in scenarios previously considered hopeless.\n> \n> And it laid the foundation for automotive crash testing. If humans could survive 46g, then the question became: How do we design vehicles so that occupants never experience more than they can tolerate?\n> \n> Stapp's data made modern crash safety possible.\n\n---\n\n## SLIDE 24: The Lesson\n**Visual:** Quote  \n**Text:** \"Assumptions are not data. Test it. Measure it. Know for certain.\"\n\n### Speaker Notes:\n> The lesson: Assumptions are not data.\n> \n> For years, everyone \"knew\" that 18g was fatal. Nobody had tested it. They just assumed.\n> \n> Stapp tested it. He measured it. And he proved them wrong.\n> \n> This is the foundation of everything we do. Don't assume. Test. Measure. Know for certain.\n\n---\n\n## SLIDE 25: Puzzle 5 Introduction\n**Visual:** Section divider  \n**Title:** PUZZLE 5: The Airbag Arms Race\n\n### Speaker Notes:\n> Last puzzle. I call this one the Airbag Arms Race.\n\n---\n\n## SLIDE 26: The Setup\n**Visual:** Timeline graphic  \n**1970:** Airbags proposed  \n**1984:** First mandates  \n**1998:** Full mandate  \n**2000s:** \"Advanced\" airbags\n\n### Speaker Notes:\n> The history of airbag regulation is fascinating.\n> \n> 1970: Airbags first proposed as an alternative to seatbelts.\n> 1984: First automatic restraint requirements (airbag OR automatic belt).\n> 1998: Airbags mandatory in all vehicles.\n> 2000s: \"Advanced\" airbags with occupant classification.\n> \n> Each generation, airbags got more sophisticated. More sensors. More inflation stages. More intelligence.\n> \n> Here's the question: How much faster did airbag technology advance during the mandate period versus before?\n\n---\n\n## SLIDE 27: The Reveal\n**Visual:** Comparison  \n**Pre-mandate (1970-1984):** Minimal innovation  \n**Post-mandate:** Explosion of patents, technologies, features\n\n### Speaker Notes:\n> The answer is dramatic.\n> \n> Before mandates, airbag technology advanced slowly. Why invest in something that wasn't required?\n> \n> After mandates, innovation exploded. Multi-stage inflators. Occupant sensors. Position detection. Seatbelt pretensioner integration. Side airbags. Curtain airbags. Knee airbags.\n> \n> The regulation created the market. The market drove innovation. And the innovation saved lives.\n\n---\n\n## SLIDE 28: The Data That Drove It\n**Visual:** Graph  \n**Text:** \"Lives saved by airbags: From 0 (1985) to ~2,800/year (today)\"\n\n### Speaker Notes:\n> Today, airbags save approximately 2,800 lives per year in the United States.\n> \n> That didn't happen because of voluntary adoption. It happened because regulation required it, testing proved it worked, and data validated each improvement.\n> \n> Without crash testing data, you couldn't prove an airbag design was better. Without that proof, you couldn't justify the R&D investment. Without the investment, you couldn't innovate.\n> \n> Data is the engine of safety progress.\n\n---\n\n## SLIDE 29: The Meta-Lesson\n**Visual:** Text  \n**Quote:** \"Measurement isn't just about understanding what happened. It's about enabling what comes next.\"\n\n### Speaker Notes:\n> Here's the meta-lesson from all five puzzles.\n> \n> Measurement isn't just about understanding what happened. It's about enabling what comes next.\n> \n> The beautiful wreck taught us that crush zones work.\n> The rollover data taught us that ejection was the real problem.\n> The small overlap test taught us that we'd missed a vulnerability.\n> Stapp's sled taught us what humans can survive.\n> The airbag arms race taught us that mandates drive innovation.\n> \n> In every case, data didn't just describe - it enabled. It pointed the way forward.\n\n---\n\n## SLIDE 30: Implications for DTS\n**Visual:** Connection to DTS products  \n**Text:** \"Our instrumentation is the source of these surprises.\"\n\n### Speaker Notes:\n> What does this mean for DTS?\n> \n> Our instrumentation is the source of these surprises. When data contradicts expectations, it's because someone measured something that hadn't been measured before. Or measured it more precisely. Or measured it in a new context.\n> \n> Every sensor we design, every data acquisition system we build, every calibration we perform - it's potentially the source of the next surprise. The next counterintuitive finding that changes how vehicles are built.\n> \n> That's a remarkable responsibility. And a remarkable opportunity.\n\n---\n\n## SLIDE 31: Your Turn\n**Visual:** Challenge  \n**Text:** \"What assumptions are we making today that data will overturn tomorrow?\"\n\n### Speaker Notes:\n> I want to leave you with a challenge.\n> \n> What assumptions are we making today that data will overturn tomorrow?\n> \n> In the 1950s, everyone assumed 18g was fatal. Wrong.\n> In the 2000s, everyone assumed roof crush was the rollover killer. Wrong.\n> In 2011, everyone assumed luxury cars were safer. Wrong.\n> \n> What are we assuming now that we haven't tested? What do we \"know\" that might not be true?\n> \n> Those are the questions that lead to the next breakthrough.\n> \n> Thank you.\n\n---\n\n## SLIDE 32: Questions\n**Visual:** \"Questions?\"  \n**Subtitle:** Ben - Application Engineer\n\n### Speaker Notes:\n> I'm happy to take questions. And if you've got your own \"data surprised me\" story, I'd love to hear it.\n> \n> *[Open for Q&A]*\n\n---\n\n# APPENDIX: ADDITIONAL PUZZLES (BACKUP)\n\n## Puzzle: The Safer Smaller Car\n- Setup: Large SUV vs. small car in head-on collision\n- Assumption: SUV occupant always safer\n- Reality: Depends on crash compatibility; some small cars protect better than some SUVs\n- Lesson: Mass isn't everything; structure and restraints matter\n\n## Puzzle: The Helmet That Failed\n- Setup: Two helmets - one heavy, one light\n- Assumption: Heavier = more protection\n- Reality: Lighter helmet had better SI scores due to better energy-absorbing liner\n- Lesson: Material science matters more than mass\n\n## Puzzle: The Zero-Star Five-Star\n- Setup: Same vehicle, two different NCAP programs\n- Assumption: Rating should be consistent\n- Reality: Different test protocols, different dummies, different results\n- Lesson: Test protocol details matter enormously\n\n## Puzzle: The Unbreakable Neck\n- Setup: Early dummy neck designs\n- Assumption: Stiff neck provides realistic injury measurement\n- Reality: Too stiff = underestimate injury risk; too flexible = overestimate\n- Lesson: Biofidelity is a constant calibration challenge\n\n---\n\n# TIMING GUIDE\n\n| Section | Duration | Cumulative |\n|---------|----------|------------|\n| Opening (Slides 1-2) | 3 min | 3 min |\n| Puzzle 1 - Beautiful Wreck (Slides 3-7) | 7 min | 10 min |\n| Puzzle 2 - Survivor's Paradox (Slides 8-13) | 7 min | 17 min |\n| Puzzle 3 - Luxury Failure (Slides 14-18) | 8 min | 25 min |\n| Puzzle 4 - 46.2g Man (Slides 19-24) | 8 min | 33 min |\n| Puzzle 5 - Airbag Arms Race (Slides 25-28) | 6 min | 39 min |\n| Closing (Slides 29-32) | 4 min | 43 min |\n| Q&A Buffer | 2 min | 45 min |\n\n---\n\n# ENGAGEMENT TECHNIQUES\n\n1. **Polling:** Ask audience to guess before reveals. Show of hands or verbal responses.\n2. **Pause:** Give time for guesses. Don't rush to the answer.\n3. **Callback:** Reference earlier puzzles when discussing later ones.\n4. **Humor:** The surprises are inherently engaging - lean into the \"gotcha\" moment.\n5. **Validation:** When audience guesses right, acknowledge it.\n6. **Discussion:** For some puzzles, open brief discussion before revealing.\n\n---\n\n# VISUAL NOTES\n\n- Use high-contrast reveals (gray \"hidden\" state, then color)\n- Include actual data traces where possible\n- Photos of actual crashes add credibility\n- Keep slides uncluttered - one main point per slide\n- Consider animation for reveals (build in PowerPoint)\n\n---\n\n*End of Script and Speaker Notes*\n"

# Conversation Summary: DTS Safety Testing Presentation Project

## Project Overview
We are helping **Ben**, an Application Engineer at **Diversified Technical Systems (DTS)**, create presentation materials. DTS manufactures data acquisition systems and instrumentation used in crash testing - they provide the "nervous system" for crash test dummies.

## Working Directory
`/Users/noise/Documents/obsidian/safetytesting/`

---

## What We've Created

### Phase 1: Test Modes Reference (One Slide Per Test)
Created comprehensive technical reference materials covering all major safety test modes:

| File | Location | Description |
|------|----------|-------------|
| `test_modes_slides.md` | Root | 1,246 lines - Complete markdown reference with 27 test modes + 5 section dividers |
| `Test_Modes_Reference.pptx` | Root | 7.1 MB, 33 slides - PowerPoint version with images |
| `create_test_modes_pptx.py` | Root | Python script to generate the PowerPoint |

**Test Modes Covered:**
- **NHTSA/FMVSS (8):** FMVSS 208 Frontal, 214 Side MDB, 214 Side Pole, 216 Roof Crush, 301 Fuel System, 208 OOP, 213 Child Restraint, 201 Interior Impact
- **IIHS (8):** Moderate Overlap, Small Overlap, Side 2021, Roof Strength, Whiplash, FCP V2V, Headlights, Pedestrian AEB
- **NCAP (3):** NHTSA NCAP Frontal, Side, Euro NCAP MPDB
- **Pedestrian (3):** Legform, Headform, AEB Pedestrian/Cyclist
- **Sports/Helmets (5):** NOCSAE Football Drop, Linear Impactor, Lacrosse, Hockey, FMVSS 218 Motorcycle

Each slide includes: Purpose, Test Setup, Dummy & Instrumentation, Injury Criteria & Limits

---

### Phase 2: Three 45-Minute Internal Presentations
Created for Ben to present to DTS engineering and internal staff:

#### Presentation 1: "The Stories Our Data Tells" (RECOMMENDED)
**Location:** `The_Stories_Our_Data_Tells/`
- `script_and_speaker_notes.md` - Complete script with timing guide
- `create_presentation.py` - Generator script
- `The_Stories_Our_Data_Tells.pptx` - 27 slides

**Structure:**
- Part 1: Data Behind Headlines (Airbags, Small Overlap, Football)
- Part 2: Surprising Applications (Military, Space, Theme Parks)
- Part 3: Good Data Enables Good Decisions
- Theme: Connect DTS work to real lives saved

00022| # SLIDE-BY-SLIDE SCRIPT AND SPEAKER NOTES
00023| 
00024| ---
00025| 
00026| ## SLIDE 1: Title Slide
00027| **Title:** The Stories Our Data Tells  
00028| **Subtitle:** How DTS Helps Save Lives
00029| 
00030| ### Speaker Notes:
00031| > *[Walk to center stage, pause, make eye contact with audience]*
00032| > 
00033| > Good morning everyone. I'm Ben, and I've spent the last [X] years as a field application engineer, which means I get to see something most of you don't - I get to see what happens to our equipment after it leaves this building.
00034| > 
00035| > Today I want to share some stories with you. Not technical specifications or product roadmaps - stories. Because behind every data channel we design, every product we ship, every calibration we perform... there's a human story.
00036| > 
00037| > Let me start with a number.
00038| 
00039| ---
00040| 
00041| ## SLIDE 2: The Number That Matters
00042| **Visual:** Large "117,000" in center  
00043| **Subtitle:** Lives saved every year in the U.S. alone
00044| 
00045| ### Speaker Notes:
00046| > One hundred seventeen thousand.
00047| > 
00048| > That's how many people are alive today, this year, who would have died on American roads if we still had 1970s vehicle safety.
00049| > 
00050| > In 1970, the fatality rate was 4.7 deaths per 100 million vehicle miles traveled. Today it's about 1.1. Same roads. More cars. More miles. But 77% fewer deaths per mile driven.
00051| > 
00052| > *[Pause]*
00053| > 
00054| > That didn't happen by accident. It happened because of data. Data that came from instrumentation. Instrumentation that companies like DTS build.
00055| > 
00056| > Every accelerometer we ship, every data acquisition system we calibrate, every channel of data we help capture - it's part of this.
00057| 
00058| ---
00059| 
00060| ## SLIDE 3: A Crashed Car is Gone Forever
00061| **Visual:** Photo of crashed test vehicle  
00062| **Quote:** "A crashed car is destroyed in milliseconds. The data is what remains."
00063| 
00064| ### Speaker Notes:
00065| > Here's something I tell customers all the time: A crashed car is gone forever. In about 150 milliseconds, a $50,000 test vehicle becomes scrap metal.
00066| > 
00067| > But the data? The data lives on. The data gets analyzed, debated, published. The data drives regulation. The data changes designs. The data saves the next generation of occupants.
00068| > 
00069| > That's what we do. We're not just building data acquisition systems. We're building the memory of every crash test ever run.
00070| > 
00071| > Let me show you what I mean with three stories from the field.
00072| 
00073| ---
00074| 
00075| ## SLIDE 4: Part 1 - The Headlines
00076| **Visual:** Section divider  
00077| **Title:** PART 1: The Data Behind the Headlines
00078| 
00079| ### Speaker Notes:
00080| > You've all seen safety recalls in the news. You've seen crash test ratings. You've maybe heard about the airbag crisis or the Ford Explorer rollovers.
00081| > 
00082| > What you might not know is that behind every one of those headlines, there's data. Specific data. Data channels that revealed what was happening. Data that DTS equipment helped capture.
00083| > 
00084| > Let me take you behind three headlines.
00085| 
00086| ---
00087| 
00088| ## SLIDE 5: Story 1 - The Airbag That Killed
00089| **Visual:** Newspaper headline - "Airbag Kills Child in Minor Crash"  
00090| **Subtitle:** 1990s Airbag Crisis
00091| 
00092| ### Speaker Notes:
00093| > *[Pause for effect]*
00094| > 
00095| > 1996. A mother is driving her 6-year-old daughter to school. They're rear-ended at maybe 15 miles per hour. A minor fender-bender.
00096| > 
00097| > The airbag deploys. The child, sitting in the front seat, is killed instantly.
00098| > 
00099| > This wasn't a freak accident. Between 1990 and 1997, airbags killed over 175 people - mostly children and small adults. The very safety device designed to save them was killing them.
00100| > 
00101| > The question everyone was asking: Why?
00102| 
00103| ---
00104| 
00105| ## SLIDE 6: What the Data Revealed
00106| **Visual:** Data trace showing airbag deployment force - high spike  
00107| **Annotation:** Peak inflation force, deployment timing
00108| 
00109| ### Speaker Notes:
00110| > Here's what the data showed.
00111| > 
00112| > *[Point to trace]*
00113| > 
00114| > This is an airbag deployment trace. Look at that spike. Early airbags were designed for one scenario: an unbelted 50th percentile male in a 30 mph crash. They inflated with explosive force - about 200 mph.
00115| > 
00116| > But who was actually getting hit by these airbags? Children. Small women. People sitting too close to the steering wheel.
00117| > 
00118| > The data from out-of-position testing - using accelerometers like ours in small female dummies and child dummies - showed neck loads that were off the charts. Loads that would kill.
00119| > 
00120| > This data drove everything that came next.
00121| 
00122| ---
00123| 
00124| ## SLIDE 7: The Engineering Response
00125| **Visual:** Diagram of multi-stage airbag system  
00126| **Bullet points:** Depowered bags, dual-stage inflators, occupant classification, suppression systems
00127| 
00128| ### Speaker Notes:
00129| > The engineering response was comprehensive:
00130| > 
00131| > First, immediate depowering - reducing inflation force by 20-35%. This happened in 1998.
00132| > 
00133| > Then, dual-stage inflators that could vary deployment force based on crash severity.
00134| > 
00135| > Then, occupant classification systems - weight sensors in seats that detect if a child or small adult is present.
00136| > 
00137| > Then, suppression systems that turn off the airbag entirely for rear-facing child seats.
00138| > 
00139| > Every single one of these solutions required new testing. New test protocols. New instrumentation. New data channels.
00140| > 
00141| > *[Pause]*
00142| > 
00143| > And it worked. Airbag-related fatalities dropped from over 50 per year to near zero.
00144| 
00145| ---
00146| 
00147| ## SLIDE 8: The DTS Connection
00148| **Visual:** Photo of CRABI infant dummy or small female dummy with DTS instrumentation  
00149| **Caption:** DTS accelerometers in out-of-position testing
00150| 
00151| ### Speaker Notes:
00152| > Where does DTS fit in?
00153| > 
00154| > Out-of-position testing requires precise measurements in very small packages. The forces on a child dummy's neck. The acceleration of an infant's head. The chest deflection of a 5th percentile female.
00155| > 
00156| > These measurements need to be accurate, repeatable, and small enough to fit in small dummies without affecting their biofidelity.
00157| > 
00158| > That's what we do. Our accelerometers are in the CRABI infant dummy. Our data acquisition systems capture the millisecond-by-millisecond record of what happens when an airbag meets an out-of-position occupant.
00159| > 
00160| > Without that data, there's no depowering. There's no dual-stage inflator. There's no occupant classification. And there are more dead children.
00161| 
00162| ---
00163| 
00164| ## SLIDE 9: Story 2 - The Luxury Car That Failed
00165| **Visual:** IIHS Small Overlap test photo - crumpled luxury vehicle  
00166| **Subtitle:** The 2012 Small Overlap Shock
00167| 
00168| ### Speaker Notes:
00169| > Let's move to story two. This one might surprise you.
00170| > 
00171| > 2012. The Insurance Institute for Highway Safety introduces a new test: the small overlap frontal crash. Twenty-five percent overlap, rigid barrier, 40 miles per hour.
00172| > 
00173| > The industry assumed their vehicles would do fine. After all, they'd been acing the moderate overlap test for years. Mercedes, BMW, Audi - surely they'd pass.
00174| > 
00175| > *[Pause]*
00176| > 
00177| > They didn't.
00178| 
00179| ---
00180| 
00181| ## SLIDE 10: The Results
00182| **Visual:** Table showing 2012 small overlap results  
00183| - BMW 5-Series: Marginal
00184| - Mercedes C-Class: Marginal
00185| - Audi A4: Marginal
00186| - Lexus ES: Poor
00187| 
00188| ### Speaker Notes:
00189| > Look at this list. BMW 5-Series - Marginal. Mercedes C-Class - Marginal. Audi A4 - Marginal. Lexus ES - Poor.
00190| > 
00191| > These are some of the most expensive, most prestigious vehicles on the road. And they failed a crash test.
00192| > 
00193| > Only 3 of 13 midsize cars earned "Good" in the first round of testing.
00194| > 
00195| > This was a wake-up call for the entire industry.
00196| 
00197| ---
00198| 
00199| ## SLIDE 11: What the Data Showed
00200| **Visual:** Comparison - good structure vs. poor structure (intrusion data)  
00201| **Annotation:** Firewall intrusion, footwell collapse, steering column displacement
00202| 
00203| ### Speaker Notes:
00204| > What did the data show?
00205| > 
00206| > *[Point to comparison]*
00207| > 
00208| > On the left: a vehicle with good small overlap performance. The crash structure engages, absorbs energy, and the occupant compartment stays intact.
00209| > 
00210| > On the right: a vehicle that failed. See how the structure bypasses the main longitudinal rails? The wheel gets pushed back. The firewall collapses. The footwell crushes. The steering column displaces into the occupant.
00211| > 
00212| > The dummies - instrumented with accelerometers and load cells - told the story. Head injury numbers through the roof. Leg loads exceeding injury thresholds. Feet trapped in crushed footwells.
00213| > 
00214| > This wasn't visible from looking at the car. You had to see the data.
00215| 
00216| ---
00217| 
00218| ## SLIDE 12: The Industry Response
00219| **Visual:** Before/after structural diagrams showing redesigned front end  
00220| **Caption:** Structural redesigns across the industry
00221| 
00222| ### Speaker Notes:
00223| > The industry response was massive. And fast.
00224| > 
00225| > Within two years, automakers fundamentally redesigned their front structures. They added small overlap-specific load paths. They extended the bumper beam. They reinforced the A-pillar. They changed the wheel well geometry.
00226| > 
00227| > By 2015, most vehicles were earning "Good" ratings. But it required a complete rethink of frontal crash structure.
00228| > 
00229| > And every one of those redesigned vehicles was validated with crash testing. With instrumented dummies. With data channels.
00230|

00233| ## SLIDE 13: Story 3 - The Sport That Was Killing Its Players
00234| **Visual:** Vintage football photo - leather helmets  
00235| **Subtitle:** Football's Deadly Secret
00236| 
00237| ### Speaker Notes:
00238| > Let's step outside automotive for our third story.
00239| > 
00240| > In the 1960s and early 1970s, American football was killing its players. Not occasionally - regularly. An average of 32 players died each year from head and neck injuries.
00241| > 
00242| > Thirty-two funerals. Every year. High school kids. College students. Professional athletes. All dead from a sport.
00243| > 
00244| > Helmets existed. They just didn't work.
00245| 
00246| ---
00247| 
00248| ## SLIDE 14: The NOCSAE Solution
00249| **Visual:** Drop tower test equipment  
00250| **Caption:** NOCSAE drop test - the standard that changed everything
00251| 
00252| ### Speaker Notes:
00253| > In 1969, the National Operating Committee on Standards for Athletic Equipment - NOCSAE - was formed. Their mission: create a helmet standard that would actually prevent deaths.
00254| > 
00255| > They developed the drop test. A helmeted headform dropped from 60 inches onto various anvils. The headform instrumented with accelerometers.
00256| > 
00257| > The metric they chose: Severity Index. An integral of acceleration over time, raised to the 2.5 power. If SI exceeded 1200, the helmet failed.
00258| > 
00259| > It was simple. It was repeatable. And it worked.
00260| 
00261| ---
00262| 
00263| ## SLIDE 15: The Results
00264| **Visual:** Graph showing football fatalities before and after NOCSAE  
00265| - 1970: ~32 deaths/year
00266| - 1980: ~8 deaths/year
00267| - 2020: ~3 deaths/year
00268| 
00269| ### Speaker Notes:
00270| > *[Point to graph]*
00271| > 
00272| > Look at this curve.
00273| > 
00274| > Pre-NOCSAE: 32 deaths per year.
00275| > 
00276| > After the standard was mandated in 1980: deaths dropped to single digits.
00277| > 
00278| > Today: typically 3 or fewer deaths per year from head/neck trauma in football.
00279| > 
00280| > That's a 90% reduction. Not from rule changes. Not from better coaching. From better helmets - helmets validated with instrumented testing.

00285| **Visual:** Linear impactor test setup / helmet testing equipment  
00286| **Caption:** Modern helmet testing - now including rotational metrics
00287| 
00288| ### Speaker Notes:
00289| > DTS instrumentation is used in helmet testing facilities around the world.
00290| > 
00291| > Our accelerometers are in the headforms. Our data acquisition systems capture the impact data. Our calibration standards ensure that a test run in Kansas gives the same result as a test run in Virginia.
00292| > 
00293| > And the science keeps advancing. The original drop test measured linear acceleration. Today, we're adding rotational acceleration - because we now understand that concussions are caused by brain rotation, not just linear impact.
00294| > 
00295| > That means new sensors. New data channels. New measurement techniques. The same DTS capabilities that serve automotive are now serving sports safety.

00312| **Caption:** Protecting soldiers from IED underbody blast
00313| 
00314| ### Speaker Notes:
00315| > The military has a problem. IEDs - improvised explosive devices - are killing soldiers by sending blast forces up through vehicle floors.
00316| > 
00317| > Traditional crash test dummies weren't designed for this. They measure horizontal impact, not vertical blast.
00318| > 
00319| > So the Army developed WIAMan - the Warrior Injury Assessment Manikin. A dummy specifically designed for underbody blast assessment.
00320| > 
00321| > *[Pause]*
00322| > 
00323| > DTS was a key partner in developing WIAMan's instrumentation. Our accelerometers measure the lumbar spine loads that determine whether a soldier's back is broken. Our data acquisition systems capture the blast event.
00324| > 
00325| > This isn't automotive. But it's the same mission: use data to save lives.

00332| 
00333| ### Speaker Notes:
00334| > When a space capsule returns to Earth, it hits the water - or land - hard. Potentially 15g or more of deceleration.
00335| > 
00336| > How do you know if the astronauts will survive? You test. With instrumented dummies. With accelerometers. With data acquisition systems.
00337| > 
00338| > DTS equipment has been used to validate crew seating in multiple space programs. The same measurement principles that protect car occupants protect astronauts returning from orbit.

00345| 
00346| ### Speaker Notes:
00347| > Here's one you might not expect: theme parks.
00348| > 
00349| > Roller coasters are designed to create excitement through acceleration. But there are limits - exceed them, and you injure guests.
00350| > 
00351| > ASTM standards specify acceleration limits for amusement rides. And how do you verify that a new roller coaster meets those limits? You instrument it. You measure the g-forces. You capture the data.
00352| > 
00353| > Some theme parks use DTS equipment for this. Same accelerometers. Same data acquisition. Different application.
00354|

00359| **Caption:** Validating devices that go inside human bodies
00360| 
00361| ### Speaker Notes:
00362| > Medical devices like spinal implants or joint replacements experience repeated loading inside the body. Drop something? An impact load.
00363| > 
00364| > Device manufacturers need to know: will this implant survive real-world conditions?
00365| > 
00366| > Impact testing of medical devices uses the same principles as crash testing. Controlled impacts. Measured forces. Data analysis. Some of that testing uses DTS equipment.

00376| > 
00377| > What do they all have in common?
00378| > 
00379| > They all need precise measurement of dynamic events. Events that happen in milliseconds. Events that determine whether someone lives or dies, walks or doesn't, returns from space or doesn't.
00380| > 
00381| > That's what DTS does. We provide the measurement capability that enables safety engineering across all these fields.

00390| > Let me shift gears and talk directly to the engineers in the room.
00391| > 
00392| > Everything I've shown you - the airbag fixes, the structural redesigns, the helmet improvements - all of it depends on one thing: good data.
00393| > 
00394| > Bad data leads to bad decisions. And in safety engineering, bad decisions cost lives.
00395| > 
00396| > Let me show you what I mean.

00400| ## SLIDE 24: What Good Data Looks Like
00401| **Visual:** Clean data trace with proper characteristics  
00402| **Annotations:** Pre-trigger baseline, appropriate filter, clear signal, no saturation
00403| 
00404| ### Speaker Notes:
00405| > Here's what good data looks like.
00406| > 
00407| > *[Point to features]*
00408| > 
00409| > Clean pre-trigger baseline - the sensor was working before the event.
00410| > 
00411| > Appropriate filtering - CFC 1000 for head acceleration, removing noise without distorting the signal.
00412| > 
00413| > Clear signal - you can see exactly what happened, when it happened.
00414| > 
00415| > No saturation - the sensor range was appropriate for the event.
00416| > 
00417| > This is data you can trust. Data that can drive engineering decisions.
00418| 
00419| ---
00420| 
00421| ## SLIDE 25: What Bad Data Looks Like
00422| **Visual:** Problematic data traces  
00423| **Examples:** Saturated signal, excessive noise, zero shift, cable artifact
00424| 
00425| ### Speaker Notes:
00426| > And here's what bad data looks like.
00427| > 
00428| > *[Point to examples]*
00429| > 
00430| > Saturated signal - the accelerometer was overranged. We don't know what the actual peak was. Could have been 100g. Could have been 500g. We don't know.
00431| > 
00432| > Excessive noise - either electrical interference or mechanical resonance. The real signal is buried in garbage.
00433| > 
00434| > Zero shift - the sensor's baseline moved after impact. Every measurement after this point is wrong.
00435| > 
00436| > Cable artifact - that spike isn't acceleration, it's the cable being yanked.
00437| > 
00438| > *[Pause]*
00439| > 
00440| > You cannot make good engineering decisions with bad data. If a customer makes a vehicle safer based on bad data, they might be making it more dangerous.

00447| 
00448| ### Speaker Notes:
00449| > Here's why this matters for everyone in this room.
00450| > 
00451| > Every design decision you make - sensor selection, cable design, data acquisition architecture, software algorithms, calibration procedures - affects the quality of data our customers collect.
00452| > 
00453| > When you choose a sensor range, you're deciding whether customers will saturate.
00454| > 
00455| > When you design a mounting system, you're determining whether they'll get resonance artifacts.
00456| > 
00457| > When you write calibration procedures, you're setting the accuracy baseline for every test.
00458| > 
00459| > These aren't abstract technical decisions. They're decisions that determine whether an engineer at GM or Toyota or BMW can trust the data. And trust the conclusions they draw from it.

00467| ### Speaker Notes:
00468| > Let me paint the picture.
00469| > 
00470| > You design a product. That product goes to a customer. The customer runs a test. The test generates data. That data influences a design decision. That design goes into a vehicle. That vehicle is manufactured a million times. Those million vehicles protect millions of occupants.
00471| > 
00472| > The ripple effect of your work is enormous. You might never see it. You might never know about it. But it's there.
00473| > 
00474| > Every calibration. Every design review. Every manufacturing check. They all matter.

00498| > Not the test lab. Not the automotive OEM. Not the government regulator.
00499| > 
00500| > The real customers are the people who will sit in the vehicles that get designed using our data. The children who ride in car seats validated with our instrumentation. The soldiers protected by armor tested with our equipment. The athletes wearing helmets certified with our measurement systems.
00501| > 
00502| > They don't know our name. They don't know what DTS is. But their lives depend on us doing our jobs well.

00509| 
00510| ### Speaker Notes:
00511| > And the work isn't done.
00512| > 
00513| > Electric vehicles have different crash characteristics - battery integrity, high-voltage safety.
00514| > 
00515| > Autonomous vehicles need validation of active safety systems in ways we're still figuring out.
00516| > 
00517| > Pedestrian and cyclist fatalities are rising even as occupant fatalities fall - new protection challenges.
00518| > 
00519| > Military threats evolve constantly.
00520| > 
00521| > Sports science is discovering new mechanisms of brain injury.
00522| > 
00523| > Every one of these challenges will require new testing. New instrumentation. New data. New solutions from companies like DTS.

00528| **Visual:** Simple text on dark background  
00529| **Quote:** "Every channel of data tells a story. Make sure it's accurate enough to save a life."
00530| 
00531| ### Speaker Notes:
00532| > I'll leave you with this.
00533| > 
00534| > Every channel of data tells a story. A story about what happened in a crash test. A story about forces and accelerations and human tolerance. A story that will be read by engineers making decisions about vehicle design.
00535| > 
00536| > Make sure those stories are accurate. Make sure they're reliable. Make sure they're precise.
00537| > 
00538| > Because somewhere, someday, a vehicle designed using data from our equipment will be in a crash. And the person inside will either walk away or they won't.
00539| > 
00540| > That's the story our data tells. Let's make sure we're telling it right.
00541| >

00037| ### Speaker Notes:
00038| > *[Start with silence. Let the room settle.]*
00039| > 
00040| > Every safety standard was written in blood.
00041| > 
00042| > That's not a metaphor. It's literal truth. Behind every FMVSS regulation, every IIHS test protocol, every NOCSAE helmet standard - there are people who died.
00043| > 
00044| > Today I want to tell you four stories. Four tragedies that became triumphs. Four times when data - data captured by instrumentation like ours - made the difference between "people keep dying" and "this never happens again."
00045| > 
00046| > These stories are not easy to hear. But I think they're important. Because they remind us why we do what we do.

00051| **Visual:** Simple diagram showing the arc  
00052| **Path:** Tragedy → Investigation → Data → Solution → Triumph
00053| 
00054| ### Speaker Notes:
00055| > Every story I'm going to tell follows the same arc.
00056| > 
00057| > It starts with tragedy. Someone dies. Often many people die.
00058| > 
00059| > Then comes investigation. Engineers ask: What happened? Why?
00060| > 
00061| > Then data. We test. We measure. We quantify what went wrong.
00062| > 
00063| > Then solution. We redesign. We regulate. We change.
00064| > 
00065| > And finally, triumph. The deaths stop. Lives are saved.
00066| > 
00067| > This arc - from tragedy to triumph - is the arc of safety engineering. And data is the hinge point that makes the transformation possible.

00074| 
00075| ### Speaker Notes:
00076| > Story one. The children who were killed by safety.
00077| > 
00078| > This is perhaps the most tragic story in automotive safety history. Because the very device designed to protect - the airbag - became the killer.

00085| **Below:** "Many were children sitting in the front seat"
00086| 
00087| ### Speaker Notes:
00088| > Between 1990 and 1997, airbags killed over 175 people.
00089| > 
00090| > Most of them were children. Some were small women. Some were people who sat too close to the steering wheel.
00091| > 
00092| > *[Pause - let this land]*
00093| > 
00094| > The youngest victim I know of was 1 month old. Killed by an airbag while riding in a rear-facing car seat placed in the front passenger position.
00095| > 
00096| > These weren't high-speed crashes. These were fender-benders. 10 mph impacts. Situations where everyone should have walked away.
00097| > 
00098| > Instead, parents watched their children die from the very device that was supposed to protect them.

00105| 
00106| ### Speaker Notes:
00107| > The question was devastating: Why?
00108| > 
00109| > Airbags had been sold as the ultimate safety device. They would save 12,000 lives per year, the government said. And they were saving lives - adult male lives, mostly.
00110| > 
00111| > But they were also killing. And the deaths were concentrated among a specific population: Children. Small women. Anyone who wasn't a large adult male.
00112| > 
00113| > Engineers had to find out why. And the only way to find out was to test.

00122| > The investigation centered on out-of-position testing.
00123| > 
00124| > What happens when someone isn't sitting in the ideal position? What happens when they're too close to the airbag? What happens when they're small?
00125| > 
00126| > Researchers put instrumented dummies - small female dummies, child dummies, infant dummies - in various positions relative to the airbag. And then they deployed the airbag.
00127| > 
00128| > The dummies were instrumented with accelerometers and load cells. The same kinds of sensors DTS makes today.

00134| **Annotations:** "Peak neck tension: 3,500 N" / "Injury threshold: 1,600 N"
00135| 
00136| ### Speaker Notes:
00137| > The data was horrifying.
00138| > 
00139| > Early airbags inflated at roughly 200 miles per hour. When that explosion hit a small child positioned close to the bag, the neck loads were catastrophic.
00140| > 
00141| > The injury threshold for a child's neck is about 1,600 Newtons. The data showed loads of 3,500 Newtons or more. More than double the fatal threshold.
00142| > 
00143| > The airbags weren't just dangerous - they were essentially guaranteed to kill children in certain positions.
00144| > 
00145| > But without the data, no one would have known exactly why. And without knowing why, you can't engineer a solution.

00150| **Visual:** Diagram showing multi-stage airbag system components  
00151| **Bullets:** Depowered bags, dual-stage, occupant classification, suppression
00152| 
00153| ### Speaker Notes:
00154| > The data drove a cascade of engineering solutions:
00155| > 
00156| > First, in 1998, immediate depowering. Reduce the inflation force by 20-35%. Accept that some large males in severe crashes might not be perfectly protected, in exchange for not killing children.
00157| > 
00158| > Second, dual-stage inflators. Variable deployment force based on crash severity. Light crash? Light deployment.
00159| > 
00160| > Third, occupant classification. Weight sensors in seats to detect children and small adults. Adjust or suppress the airbag accordingly.
00161| > 
00162| > Fourth, suppression for rear-facing child seats. If a sensor detects a rear-facing seat, the airbag turns off completely.
00163| > 
00164| > Each of these solutions required new testing. New data. New validation that the fix actually worked.

00171| 
00172| ### Speaker Notes:
00173| > The triumph: Airbag fatalities dropped from over 50 per year to essentially zero.
00174| > 
00175| > Modern airbags are smart. They detect who's in the seat. They know how severe the crash is. They deploy with appropriate force - or don't deploy at all.
00176| > 
00177| > And those 50+ people per year who used to die? They're alive. Every year, those 50 people go home to their families instead of going to the morgue.
00178| > 
00179| > That's what data did. Data turned a child-killing device into a life-saving device.

00197| 
00198| ### Speaker Notes:
00199| > The Ford Pinto was a bestseller in the 1970s. Small, cheap, fuel-efficient during the oil crisis.
00200| > 
00201| > It had one problem: The gas tank was mounted behind the rear axle, only 9 inches from the rear bumper.
00202| > 
00203| > In a rear-end collision - even at moderate speed - the rear crumpled into the gas tank. The tank ruptured. Fuel sprayed. A spark ignited it.
00204| > 
00205| > And people burned to death inside their cars.
00206| > 
00207| > It's impossible to know the exact death toll. Estimates range from 27 to several hundred. What we know for certain: Ford knew about the problem before anyone died.

00219| > 
00220| > This is from an actual internal Ford memo.
00221| > 
00222| > The cost to fix the problem: $11 per car. Eleven dollars. For 12.5 million vehicles, that's $137 million.
00223| > 
00224| > The "benefit" of fixing it - in Ford's calculation - was 180 fewer deaths. At $200,000 per death (their number), that's $36 million.
00225| > 
00226| > Cost exceeds benefit. Don't fix it.
00227| > 
00228| > *[Pause]*

00238| ### Speaker Notes:
00239| > The data that should have driven the decision was clear.
00240| > 
00241| > Rear impact testing showed fuel leakage far exceeding safe limits. The tank design failed at impacts as low as 25 mph.
00242| > 
00243| > Ford's own engineers knew. They had the data. But the data didn't make it past the accounting department.
00244| > 
00245| > After the scandal broke, after the lawsuits, after the criminal charges - the federal government strengthened FMVSS 301, the fuel system integrity standard.
00246| > 
00247| > Now every vehicle is tested. Rear impact at 50 mph. Side impact at 20 mph. Rollover in 360 degrees. Fuel leakage is measured precisely - using instrumentation - and limits are enforced.

00254| 
00255| ### Speaker Notes:
00256| > The solutions were straightforward - and cheap.
00257| > 
00258| > That $11 fix? It included a plastic shield to protect the tank, reinforced bumper mounts, and better tank location.
00259| > 
00260| > Today, fuel system integrity is non-negotiable. Tanks are mounted in protected locations. They're designed to deform without rupturing. Fuel lines are self-sealing.
00261| > 
00262| > And critically: Every design is tested. Instrumented. Measured. You can't claim safety without proving it with data.

00271| > The triumph: Vehicle fire deaths have dropped 76% since 1980.
00272| > 
00273| > Some of that is better firefighting. Some is better rescue. But much of it is engineering: Vehicles simply don't catch fire like they used to.
00274| > 
00275| > The Pinto scandal forced the industry to take fuel system safety seriously. It forced regulators to mandate testing. And it established the principle that safety decisions must be based on data, not cost-benefit analysis.

00294| ### Speaker Notes:
00295| > By 2010, frontal crash safety was considered a solved problem. Vehicles were acing the federal full-frontal test. They were acing the IIHS moderate overlap test. Deaths were down.
00296| > 
00297| > But IIHS researchers noticed something in real-world crash data. People were still dying in frontal crashes. And they were dying in a specific pattern.
00298| > 
00299| > Tree strikes. Pole strikes. Corner-to-corner with other vehicles. Crashes where only 20-25% of the vehicle's width was engaged.
00300| > 
00301| > These "small overlap" crashes weren't captured by existing tests. The vehicles that aced the 40% overlap test? They were failing in real crashes.

00329| > 
00330| > And they failed. Only 3 of 13 midsize cars earned "Good" in the first round.
00331| > 
00332| > The data showed catastrophic intrusion. Footwells collapsed. Steering columns displaced. Dummies' heads struck hard interior surfaces. Feet were trapped in crushed metal.
00333| > 
00334| > The instrument data told the story: HIC values exceeding limits. Femur loads off the charts. Lower leg compression in the critical injury range.

00342| ### Speaker Notes:
00343| > The industry responded with remarkable speed.
00344| > 
00345| > Within two years, most manufacturers had fundamentally redesigned their front structures. They added small overlap load paths. Extended bumper beams. Reinforced A-pillars.
00346| > 
00347| > By 2015, most vehicles were earning "Good" ratings. The test that humbled the industry became the test that improved the industry.
00348| > 
00349| > But it took instrumented testing to prove the problem. Without precise measurement of what was happening to the dummies - the head injury values, the leg loads, the chest compression - you couldn't quantify the failure. And you couldn't prove that the redesign worked.

00416| > 
00417| > Other helmets - including some market leaders - showed SI values of 1500, 1800, 2000. They weren't just failing; they weren't even close to passing.
00418| > 
00419| > Players were wearing helmets that provided almost no protection. And nobody knew - because nobody had measured.
00420| > 
00421| > NOCSAE measurement changed that. Suddenly there was objective data. Helmets either worked or they didn't. And you could prove which was which.

00429| ### Speaker Notes:
00430| > The solution was elegant: Set a standard, and let the market respond.
00431| > 
00432| > NOCSAE established the SI < 1200 requirement. In 1980, the NCAA mandated that all helmets meet the standard. High school federations followed.
00433| > 
00434| > Suddenly, helmet manufacturers had to design for performance, not just appearance. Helmets got better liners. Better shells. Better overall performance.
00435| > 
00436| > And the standard kept evolving. In 2016, NOCSAE added the linear impactor test for rotational injury assessment. The science advances; the standard advances.

00445| > The triumph: Football deaths from head and neck injuries dropped by over 90%.
00446| > 
00447| > From 32 per year to typically 3 or fewer. Hundreds of lives saved every year.
00448| >

00498| > 
00499| > Electric vehicles are crashing differently. Batteries are bringing new failure modes. We need new instrumentation.
00500| > 
00501| > Autonomous vehicles need validation of active safety. Not just "what happens in a crash" but "did the vehicle avoid the crash?" That's new measurement territory.
00502| > 
00503| > Pedestrian and cyclist deaths are rising even as occupant deaths fall. We need instrumentation for active pedestrian protection systems.
00504| > 
00505| > Concussion science is revealing that rotational acceleration matters as much as linear. We need sensors that capture rotation.
00506| > 
00507| > Each of these challenges will follow the same arc. There will be tragedies. There will be investigations. There will be data. And there will be solutions.
00508| > 
00509| > DTS will be part of that arc - providing the instrumentation that turns tragedy into triumph.

00518| > I want to leave you with this thought.
00519| > 
00520| > Behind every safety standard is someone who didn't come home. A child killed by an airbag. A mother burned in a Pinto. A driver crushed in a small overlap crash. A football player who never got up.

00522| > Those deaths can't be undone. But data - accurate, reliable, precise data - ensures that their loss wasn't in vain.
00523| > 
00524| > The data we capture enables the engineering changes that prevent the next death. And the next. And the next.

00579| # EMOTIONAL MANAGEMENT NOTES
00580| 
00581| This presentation deals with heavy subject matter. Consider:
00582| 
00583| 1. **Pacing:** Don't rush through the tragedy sections. Let them land.
00584| 2. **Transitions:** Use silence between stories to reset emotional baseline.
00585| 3. **Resolution:** Always end each story on the triumph. Don't leave audience in despair.
00586| 4. **Self-care:** Check in with yourself before presenting. These stories can be draining.
00587| 5. **Audience:** Watch for signs of distress. Have an out if needed.

00030| **Title:** When the Data Surprised Us  
00031| **Subtitle:** Counterintuitive Findings from the Field
00032| 
00033| ### Speaker Notes:
00034| > Welcome to my favorite presentation to give. This is the one where I get to be a game show host.
00035| > 
00036| > Over the years in the field, I've seen things that made me say, "Wait, that can't be right." Results that defied expectations. Data that contradicted what everyone assumed.
00037| > 
00038| > Today I'm going to share some of those stories. And I'm going to make you guess before I reveal the answer.
00039| > 
00040| > Fair warning: Some of these will mess with your head. That's the point.

00044| ## SLIDE 2: The Rules of the Game
00045| **Visual:** Numbered list  
00046| **Content:**
00047| 1. I'll show you a scenario
00048| 2. You guess what happened
00049| 3. I reveal the data
00050| 4. We discuss why it matters
00051| 
00052| ### Speaker Notes:
00053| > Here are the rules.
00054| > 
00055| > I'll show you a scenario. You'll have a few seconds to think about what you expect the data to show.
00056| > 
00057| > Then I'll reveal what actually happened. Sometimes you'll be right. Often you won't.
00058| > 
00059| > And then we'll talk about why it matters for the work we do.
00060| >

00074| ## SLIDE 4: The Setup - Two Cars
00075| **Visual:** Two post-crash photos side by side  
00076| **Car A:** Severely crumpled front end, pushed back, visually destroyed  
00077| **Car B:** Relatively intact, minimal visible damage
00078| 
00079| ### Speaker Notes:
00080| > Here are two cars after frontal crash tests. Same test. Same speed. Same barrier.
00081| > 
00082| > Car A - on the left - is destroyed. The front end is pushed back almost to the firewall. The hood is crumpled like paper. It looks catastrophic.
00083| > 
00084| > Car B - on the right - looks pretty good. Some crumpling, sure, but the structure held. The passenger compartment looks intact.
00085| > 
00086| > *[Pause]*
00087| > 
00088| > Quick poll: Which car do you think had better occupant protection? Which car would you rather be in during a crash?
00089| > 
00090| > *[Wait for audience response - most will say Car B]*
00091| 
00092| ---
00093| 
00094| ## SLIDE 5: The Reveal
00095| **Visual:** Data comparison  
00096| **Car A (destroyed):** HIC 485, Chest 38mm, Femur 4.2 kN - ALL GOOD  
00097| **Car B (intact):** HIC 890, Chest 58mm, Femur 9.1 kN - MARGINAL/POOR
00098| 
00099| ### Speaker Notes:
00100| > *[Dramatic pause]*
00101| > 
00102| > The destroyed car - Car A - had excellent dummy numbers. HIC of 485. Chest deflection of 38 millimeters. Femur load of 4.2 kilonewtons.
00103| > 
00104| > The intact-looking car - Car B - had terrible dummy numbers. HIC of 890. Chest deflection of 58 millimeters. Femur load just under the injury threshold.
00105| > 
00106| > *[Let this sink in]*
00107| > 
00108| > You would rather be in the car that looked destroyed.

00112| ## SLIDE 6: Why This Happens
00113| **Visual:** Energy absorption diagram  
00114| **Caption:** Crush zone is designed to absorb energy - that's the point
00115| 
00116| ### Speaker Notes:
00117| > Why does this happen?
00118| > 
00119| > Because crush zones are supposed to crush. That's their job. They absorb energy by deforming. The more they crumple, the more energy they absorb before it reaches the occupant.
00120| > 
00121| > Car A crumpled beautifully. It extended the deceleration pulse. It gave the occupant more time to slow down. Less force on the body.
00122| > 
00123| > Car B didn't crumple enough. It was too stiff. The deceleration pulse was short and sharp. The occupant hit a wall of g-forces.
00124| > 
00125| > Looking at the car tells you nothing about occupant safety. Only the data does.
00126|

00128| 
00129| ## SLIDE 7: The Lesson
00130| **Visual:** Quote  
00131| **Text:** "Never judge a crash by looking at the car. Judge it by looking at the data."
00132| 
00133| ### Speaker Notes:
00134| > The lesson: Never judge a crash by looking at the car.
00135| > 
00136| > I've seen this mistake made by journalists writing about crash tests. "Look how much damage!" they say. And they conclude the car is unsafe.
00137| > 
00138| > They've got it backwards. The damage is the safety. The crush zone did its job.
00139| > 
00140| > This is why we need instrumentation. This is why we need data. Because what you see is not what matters.

00152| 
00153| ## SLIDE 9: The Setup - Rollover Statistics
00154| **Visual:** Statistics  
00155| **Text:** "Rollovers are only 3% of crashes, but account for 33% of fatalities"
00156| 
00157| ### Speaker Notes:
00158| > Here's a statistic that drove safety engineers crazy for years.
00159| > 
00160| > Rollovers are only about 3% of crashes. But they account for roughly a third of fatalities.
00161| > 
00162| > Obviously, we need stronger roofs, right? Prevent the roof from crushing the occupants during rollover.
00163| > 
00164| > In 2009, NHTSA doubled the roof crush requirement - from 1.5 times vehicle weight to 3 times vehicle weight.
00165| > 
00166| > Question: How much did this reduce rollover fatalities?
00167| 
00168| ---
00169| 
00170| ## SLIDE 10: The Reveal
00171| **Visual:** Graph showing minimal change  
00172| **Text:** "Rollover fatalities: Essentially unchanged after roof crush upgrade"
00173| 
00174| ### Speaker Notes:
00175| > *[Pause]*
00176| > 
00177| > Essentially unchanged.
00178| > 
00179| > Despite doubling the roof strength requirement, rollover fatalities barely moved.
00180| > 
00181| > *[Wait for reaction]*
00182| > 
00183| > How is that possible? Wasn't roof crush the problem?
00184| 
00185| ---
00186| 
00187| ## SLIDE 11: The Data Revealed the Real Problem
00188| **Visual:** Diagram showing ejection during rollover  
00189| **Text:** "70%+ of rollover fatalities involve ejection"
00190| 
00191| ### Speaker Notes:
00192| > The data revealed the real problem.
00193| > 
00194| > Over 70% of rollover fatalities involve ejection. The occupant isn't killed by the roof crushing - they're killed by being thrown from the vehicle during the roll.
00195| > 
00196| > Once you're outside the vehicle, everything is hard. The ground. Other cars. Poles. The vehicle itself rolling over you.
00197| > 
00198| > Roof crush was a secondary problem. Ejection was the primary problem.
00199| 
00200| ---
00201| 
00202| ## SLIDE 12: The Real Solution
00203| **Visual:** Side curtain airbag deployment  
00204| **Text:** "Side curtain airbags with rollover sensors: 41% reduction in ejection"
00205| 
00206| ### Speaker Notes:
00207| > The real solution was side curtain airbags.
00208| > 
00209| > Airbags that deploy during rollover and stay inflated for 5-6 seconds. Long enough to keep occupants inside the vehicle through multiple rolls.
00210| > 
00211| > Combined with better seatbelt pretensioners and rollover-sensing systems, ejection rates dropped significantly.
00212| > 
00213| > The data - ejection statistics, injury mechanisms, survival analysis - pointed to a completely different solution than the intuitive one.
00214| > 
00215| > Without data, we'd still be making roofs stronger and wondering why people were dying.
00216| 
00217| ---
00218| 
00219| ## SLIDE 13: The Lesson
00220| **Visual:** Quote  
00221| **Text:** "The obvious solution isn't always the right solution. Let the data tell you what's actually happening."
00222| 
00223| ### Speaker Notes:
00224| > The lesson: The obvious solution isn't always the right solution.
00225| > 
00226| > Everyone assumed roof crush was the killer. The data said ejection was the killer.
00227| > 
00228| > This happens more than you'd think. The assumed problem isn't the actual problem. And the only way to know is to measure.

00243| ## SLIDE 15: The Setup
00244| **Visual:** Logos of BMW, Mercedes, Audi, Lexus  
00245| **Text:** "The most expensive cars. The most prestigious brands. Decades of safety engineering."
00246| 
00247| ### Speaker Notes:
00248| > BMW. Mercedes-Benz. Audi. Lexus.
00249| > 
00250| > These are the most expensive, most prestigious car brands in the world. They employ thousands of engineers. They've been building cars for decades.
00251| > 
00252| > They all passed the moderate overlap frontal test with flying colors. Great safety records. Premium pricing partly justified by "superior safety engineering."
00253| > 
00254| > In 2012, IIHS introduced the small overlap frontal test. Twenty-five percent overlap instead of forty. Rigid barrier instead of deformable.
00255| > 
00256| > What do you think happened?
00257|

00260| ## SLIDE 16: The Reveal
00261| **Visual:** Test results with photos  
00262| **Results:**
00263| - BMW 5-Series: MARGINAL
00264| - Mercedes C-Class: MARGINAL
00265| - Audi A4: MARGINAL
00266| - Lexus ES 350: POOR
00267| 
00268| ### Speaker Notes:
00269| > *[Let the slide speak first]*
00270| > 
00271| > They failed.
00272| > 
00273| > BMW 5-Series: Marginal.
00274| > Mercedes C-Class: Marginal.
00275| > Audi A4: Marginal.
00276| > Lexus ES 350: Poor.
00277| > 
00278| > Some of the most expensive vehicles on the road couldn't pass a new crash test.
00279|

00281| 
00282| ## SLIDE 17: What the Data Showed
00283| **Visual:** Crash photos showing intrusion  
00284| **Annotations:** Footwell collapse, steering wheel displacement, head contact with structure
00285| 
00286| ### Speaker Notes:
00287| > The data told a brutal story.
00288| > 
00289| > In these vehicles, when the impact was offset to the corner, the crash forces bypassed the main structural rails. The wheel got pushed back into the footwell. The firewall collapsed. The steering column displaced into the occupant.
00290| > 
00291| > The instrumentated dummy data showed:
00292| > - Elevated HIC from head striking interior structures
00293| > - Femur loads near the injury threshold
00294| > - Lower leg compression in the danger zone
00295| > - Feet trapped in crushed footwells
00296| > 
00297| > These vehicles were engineered for the tests that existed. They weren't engineered for this test.
00298| 
00299| ---
00300| 
00301| ## SLIDE 18: The Deeper Lesson
00302| **Visual:** Text  
00303| **Quote:** "Engineering to pass a test is not the same as engineering for safety."
00304| 
00305| ### Speaker Notes:
00306| > Here's the deeper lesson.
00307| > 
00308| > Engineering to pass a test is not the same as engineering for safety.
00309| > 
00310| > These automakers had optimized for the 40% overlap test. Their structures were brilliant - for that test. But they'd inadvertently created a vulnerability at the corner.
00311| > 
00312| > This is why test protocols must evolve. This is why consumer information testing matters. And this is why we need precise data - because without it, you don't know if you've actually solved the problem or just solved one specific scenario.

00327| ## SLIDE 20: The Setup
00328| **Visual:** 1950s photo or rocket sled  
00329| **Text:** "1954: Conventional wisdom said humans could not survive more than 18g"
00330| 
00331| ### Speaker Notes:
00332| > It's 1954. The jet age is dawning. Pilots are flying faster than ever before. And they're dying.
00333| > 
00334| > Not from crashes - from ejections. Pilots ejecting from aircraft were experiencing massive g-forces. And medical authorities believed that humans could not survive more than 18g of deceleration.
00335| > 
00336| > If that was true, high-speed ejection was a death sentence. There was no point designing ejection seats for speeds beyond a certain threshold.
00337| > 
00338| > One researcher decided to test this assumption. Not with dummies. With himself.

00342| ## SLIDE 21: John Paul Stapp
00343| **Visual:** Photo of John Paul Stapp  
00344| **Text:** "Colonel John Paul Stapp - Air Force flight surgeon"
00345| 
00346| ### Speaker Notes:
00347| > Colonel John Paul Stapp. Air Force flight surgeon. And the bravest - or craziest - researcher in the history of safety testing.
00348| > 
00349| > Stapp strapped himself into a rocket sled. And he ran test after test, pushing higher and higher g-forces.
00350|

00352| 
00353| ## SLIDE 22: The Reveal
00354| **Visual:** Data display  
00355| **Text:** "December 10, 1954: 46.2g sustained. 632 mph to zero in 1.4 seconds."
00356| 
00357| ### Speaker Notes:
00358| > On December 10, 1954, Stapp rode the rocket sled to 632 miles per hour - faster than a .45 caliber bullet.
00359| > 
00360| > Then he hit the brakes.
00361| > 
00362| > In 1.4 seconds, he decelerated from 632 mph to zero. He experienced 46.2g of sustained deceleration.
00363| > 
00364| > That's more than 2.5 times what "experts" said would kill him.
00365| > 
00366| > He survived. He walked away - temporarily blinded, with burst blood vessels in his eyes, but alive and conscious.

00370| ## SLIDE 23: What the Data Revealed
00371| **Visual:** Comparison chart  
00372| **18g "limit" vs. 46.2g survival**
00373| 
00374| ### Speaker Notes:
00375| > Stapp proved that the human body could survive far more than anyone believed.
00376| > 
00377| > This data - captured by instrumentation on his sled and his body - revolutionized aviation safety. It meant ejection seats could be designed for higher speeds. It meant survival was possible in scenarios previously considered hopeless.
00378| > 
00379| > And it laid the foundation for automotive crash testing. If humans could survive 46g, then the question became: How do we design vehicles so that occupants never experience more than they can tolerate?
00380| > 
00381| > Stapp's data made modern crash safety possible.

00386| **Visual:** Quote  
00387| **Text:** "Assumptions are not data. Test it. Measure it. Know for certain."
00388| 
00389| ### Speaker Notes:
00390| > The lesson: Assumptions are not data.
00391| > 
00392| > For years, everyone "knew" that 18g was fatal. Nobody had tested it. They just assumed.
00393| > 
00394| > Stapp tested it. He measured it. And he proved them wrong.
00395| > 
00396| > This is the foundation of everything we do. Don't assume. Test. Measure. Know for certain.

00411| **1970:** Airbags proposed  
00412| **1984:** First mandates  
00413| **1998:** Full mandate  
00414| **2000s:** "Advanced" airbags
00415| 
00416| ### Speaker Notes:
00417| > The history of airbag regulation is fascinating.
00418| > 
00419| > 1970: Airbags first proposed as an alternative to seatbelts.
00420| > 1984: First automatic restraint requirements (airbag OR automatic belt).
00421| > 1998: Airbags mandatory in all vehicles.
00422| > 2000s: "Advanced" airbags with occupant classification.
00423| > 
00424| > Each generation, airbags got more sophisticated. More sensors. More inflation stages. More intelligence.
00425| > 
00426| > Here's the question: How much faster did airbag technology advance during the mandate period versus before?

00430| ## SLIDE 27: The Reveal
00431| **Visual:** Comparison  
00432| **Pre-mandate (1970-1984):** Minimal innovation  
00433| **Post-mandate:** Explosion of patents, technologies, features
00434| 
00435| ### Speaker Notes:
00436| > The answer is dramatic.
00437| > 
00438| > Before mandates, airbag technology advanced slowly. Why invest in something that wasn't required?
00439| > 
00440| > After mandates, innovation exploded. Multi-stage inflators. Occupant sensors. Position detection. Seatbelt pretensioner integration. Side airbags. Curtain airbags. Knee airbags.
00441| > 
00442| > The regulation created the market. The market drove innovation. And the innovation saved lives.

00447| **Visual:** Graph  
00448| **Text:** "Lives saved by airbags: From 0 (1985) to ~2,800/year (today)"
00449| 
00450| ### Speaker Notes:
00451| > Today, airbags save approximately 2,800 lives per year in the United States.
00452| > 
00453| > That didn't happen because of voluntary adoption. It happened because regulation required it, testing proved it worked, and data validated each improvement.
00454| > 
00455| > Without crash testing data, you couldn't prove an airbag design was better. Without that proof, you couldn't justify the R&D investment. Without the investment, you couldn't innovate.
00456| > 
00457| > Data is the engine of safety progress.

00463| **Quote:** "Measurement isn't just about understanding what happened. It's about enabling what comes next."
00464| 
00465| ### Speaker Notes:
00466| > Here's the meta-lesson from all five puzzles.
00467| > 
00468| > Measurement isn't just about understanding what happened. It's about enabling what comes next.
00469| > 
00470| > The beautiful wreck taught us that crush zones work.
00471| > The rollover data taught us that ejection was the real problem.
00472| > The small overlap test taught us that we'd missed a vulnerability.
00473| > Stapp's sled taught us what humans can survive.
00474| > The airbag arms race taught us that mandates drive innovation.
00475| > 
00476| > In every case, data didn't just describe - it enabled. It pointed the way forward.

00481| **Visual:** Connection to DTS products  
00482| **Text:** "Our instrumentation is the source of these surprises."
00483| 
00484| ### Speaker Notes:
00485| > What does this mean for DTS?
00486| > 
00487| > Our instrumentation is the source of these surprises. When data contradicts expectations, it's because someone measured something that hadn't been measured before. Or measured it more precisely. Or measured it in a new context.
00488| > 
00489| > Every sensor we design, every data acquisition system we build, every calibration we perform - it's potentially the source of the next surprise. The next counterintuitive finding that changes how vehicles are built.
00490| > 
00491| > That's a remarkable responsibility. And a remarkable opportunity.

00502| > What assumptions are we making today that data will overturn tomorrow?
00503| > 
00504| > In the 1950s, everyone assumed 18g was fatal. Wrong.

00506| > In 2011, everyone assumed luxury cars were safer. Wrong.
00507| > 
00508| > What are we assuming now that we haven't tested? What do we "know" that might not be true?

00527| # APPENDIX: ADDITIONAL PUZZLES (BACKUP)
00528| 
00529| ## Puzzle: The Safer Smaller Car
00530| - Setup: Large SUV vs. small car in head-on collision
00531| - Assumption: SUV occupant always safer
00532| - Reality: Depends on crash compatibility; some small cars protect better than some SUVs
00533| - Lesson: Mass isn't everything; structure and restraints matter
00534| 
00535| ## Puzzle: The Helmet That Failed
00536| - Setup: Two helmets - one heavy, one light
00537| - Assumption: Heavier = more protection
00538| - Reality: Lighter helmet had better SI scores due to better energy-absorbing liner
00539| - Lesson: Material science matters more than mass
00540| 
00541| ## Puzzle: The Zero-Star Five-Star
00542| - Setup: Same vehicle, two different NCAP programs
00543| - Assumption: Rating should be consistent
00544| - Reality: Different test protocols, different dummies, different results
00545| - Lesson: Test protocol details matter enormously
00546| 
00547| ## Puzzle: The Unbreakable Neck
00548| - Setup: Early dummy neck designs
00549| - Assumption: Stiff neck provides realistic injury measurement
00550| - Reality: Too stiff = underestimate injury risk; too flexible = overestimate
00551| - Lesson: Biofidelity is a constant calibration challenge

00570| # ENGAGEMENT TECHNIQUES
00571| 
00572| 1. **Polling:** Ask audience to guess before reveals. Show of hands or verbal responses.
00573| 2. **Pause:** Give time for guesses. Don't rush to the answer.
00574| 3. **Callback:** Reference earlier puzzles when discussing later ones.
00575| 4. **Humor:** The surprises are inherently engaging - lean into the "gotcha" moment.
00576| 5. **Validation:** When audience guesses right, acknowledge it.
00577| 6. **Discussion:** For some puzzles, open brief discussion before revealing.
00578| 
00579| ---
00580| 
00581| # VISUAL NOTES
00582| 
00583| - Use high-contrast reveals (gray "hidden" state, then color)
00584| - Include actual data traces where possible
00585| - Photos of actual crashes add credibility
00586| - Keep slides uncluttered - one main point per slide
00587| - Consider animation for reveals (build in PowerPoint)

## Assistant (Build · claude-opus-4-5 · 6.3s)

Done! Speaker notes have been embedded into all three PowerPoint presentations:

| Presentation | Notes Extracted | Slides Updated |
|--------------|-----------------|----------------|
| The_Stories_Our_Data_Tells.pptx | 32 | 27 |
| From_Tragedy_to_Triumph.pptx | 32 | 31 |
| When_the_Data_Surprised_Us.pptx | 32 | 32 |

**What this means for Ben:**
- When presenting in PowerPoint, he can now see speaker notes in **Presenter View** (press F5 and use dual monitors)
- Notes appear below each slide with the full script
- Stage directions like `[Pause]` and `[Point to graph]` are preserved
- No need to have the separate markdown file open during presentation

The `embed_speaker_notes.py` script is saved in the root folder if you need to re-run it after making edits to the markdown files.

---

## User

Please consider one more presentation in the same style as the past 3. It is an amalgamation of many ideas you've worked on. Something along the lines of - start with some interesting story/threads in safety testing. For each story, start with a headline. Unravel the story and finish with the resulting test mode. Show some technical details of the test mode. Show how DTS equipment is used in that test mode. Propose any improvements.

---

## Assistant (Plan · claude-opus-4-5 · 29.4s)

Great idea! This would be a powerful "capstone" presentation that ties together storytelling, technical depth, and DTS's role. Let me think through the structure and ask some clarifying questions.

## Proposed Concept: "From Headlines to Hardware"
**Subtitle:** How Tragedies Became Test Standards - And How We Measure Them

### Proposed Structure (per story):
1. **Headline** - The tragedy/incident that grabbed attention
2. **Unravel** - What happened, why it mattered, the investigation
3. **Test Mode** - The resulting standard/test protocol
4. **Technical Deep Dive** - Injury criteria, pass/fail limits, test setup
5. **DTS in Action** - Specific equipment used, data channels, placement
6. **Future Improvements** - Where the science is heading, gaps to address

---

## Questions for You:

**1. How many stories/test modes should we cover?**
- 3 stories (~15 min each) = deeper technical detail per mode
- 4-5 stories (~10 min each) = broader coverage, lighter technical
- I'd recommend **4 stories** for good balance

**2. Which test modes interest you most?** Here are strong candidates:

| Story/Headline | Resulting Test Mode | Technical Appeal |
|----------------|---------------------|------------------|
| "Airbag Kills Child" | FMVSS 208 OOP Testing | CRABI/HIII 5th, suppression sensors |
| "Luxury Cars Fail Crash Test" | IIHS Small Overlap | Structure intrusion, leg loads |
| "32 Football Deaths/Year" | NOCSAE Drop Test | SI calculation, headform accel |
| "Ford Pinto Burns" | FMVSS 301 Fuel System | Fuel leakage measurement |
| "Rollover Ejection Crisis" | FMVSS 226 Ejection Mitigation | Curtain deployment, rollover sensors |
| "Soldiers Broken by IEDs" | WIAMan/MIL-STD | Lumbar loads, underbody blast |
| "Pedestrians Still Dying" | Euro NCAP Pedestrian AEB | Legform/headform, AEB targets |
| "The Hidden Brain Injury" | NOCSAE Linear Impactor | Rotational acceleration |

**3. Audience technical level?**
- Same internal DTS staff as before?
- Or more engineering-focused (deeper into SAE J211, filter classes, calibration)?

**4. "Propose improvements" section - how bold?**
- Conservative: "Here's what the industry is discussing"
- Forward-thinking: "Here's what DTS could develop to address gaps"
- Speculative: "Here's where the science is heading in 10 years"

---

## Draft Outline (assuming 4 stories):

### Opening (5 min)
- Every test standard started as a headline
- The arc: Tragedy → Data → Standard → Lives Saved
- Preview the 4 stories

### Story 1: The Airbag Child Deaths → OOP Testing (10 min)
- Headline: "Airbag Kills 6-Year-Old in Minor Fender-Bender"
- Test: FMVSS 208 Out-of-Position
- Technical: CRABI, HIII 5th female, neck tension limits (1,600N)
- DTS: In-dummy accelerometers, SLICE micro, compact packaging
- Future: Real-time occupant classification validation

### Story 2: Luxury Failures → Small Overlap (10 min)
- Headline: "BMW, Mercedes, Audi Fail New Crash Test"
- Test: IIHS Small Overlap Frontal
- Technical: 25% overlap, rigid barrier, HIC/femur/tibia criteria
- DTS: THOR-M instrumentation, lower leg load cells
- Future: Far-side impact, oblique testing needs

### Story 3: Football Deaths → NOCSAE Drop Test (10 min)
- Headline: "32 High School Players Dead From Head Injuries"
- Test: NOCSAE Drop Test + Linear Impactor
- Technical: Severity Index, 1200 threshold, rotational metrics
- DTS: Headform accelerometers, 6DOF sensors
- Future: Brain deformation metrics, sub-concussive tracking

### Story 4: IED Blasts → WIAMan (10 min)
- Headline: "Soldiers Surviving Blasts, But Never Walking Again"
- Test: WIAMan underbody blast assessment
- Technical: Lumbar spine compression, DRI, vertical acceleration
- DTS: WIAMan instrumentation partnership, high-g sensors
- Future: Full-body blast effects, repeated exposure

00156| 
00157| ### Instrumentation
00158| | Item | Specification |
00159| |------|---------------|
00160| | ATD | None (static test) |
00161| | Measurements | Applied force, roof displacement |
00162| | Channels | ~4-6 |
00163| | Key Sensors | Load cells under plate, displacement transducers |
00164| 
00165| ### Performance Criteria
00166| | Metric | Requirement |
00167| |--------|-------------|
00168| | Strength-to-Weight Ratio | ≥ 3.0 |
00169| | Maximum Displacement | ≤ 127 mm (5 inches) before reaching 3× |
00170| | Both Sides | Must pass independently |
00171| 
00172| **Historical Note:** The original 1.5× standard was criticized as too weak. After the Ford Explorer/Firestone rollover crisis, the 2009 upgrade to 3× was implemented.
00173|

00002| ## SAE, ISO, and Other Engineering Standards
00003| ### Data Acquisition, Instrumentation, Injury Criteria, and Test Methods
00004| 
00005| ---
00006| 
00007| # OVERVIEW
00008| 
00009| This document covers the technical standards that govern HOW crash testing is performed - the instrumentation, data acquisition, filtering, injury calculations, and dummy specifications that underlie FMVSS and IIHS testing.
00010| 
00011| **Key Standards Organizations:**
00012| - **SAE International** - Society of Automotive Engineers (US-based, global influence)
00013| - **ISO** - International Organization for Standardization (global)
00014| - **UN/ECE** - United Nations Economic Commission for Europe
00015| - **NHTSA** - Defines injury criteria referenced by FMVSS
00016| 
00017| ---
00018| 
00019| # SAE J211: INSTRUMENTATION FOR IMPACT TEST
00020| 
00021| ## SAE J211-1: Instrumentation for Impact Test - Electronic Instrumentation
00022| 
00023| **First Published:** 1971
00024| **Current Version:** SAE J211-1 (Rev. 2014)
00025| **Scope:** Defines requirements for electronic instrumentation used in vehicle crash testing
00026| 
00027| ### Purpose
00028| SAE J211-1 ensures that crash test data is:
00029| - **Accurate** - Measurements reflect actual physical events
00030| - **Repeatable** - Same test produces same data across labs
00031| - **Comparable** - Data from different facilities can be compared
00032| - **Filtered appropriately** - High-frequency noise removed without distorting signal
00033| 
00034| ### Channel Frequency Classes (CFC)
00035| 
00036| The most important concept in J211 is **Channel Frequency Class** - the bandwidth of the measurement system.
00037| 
00038| | CFC | -3dB Frequency | Primary Use | Why This Bandwidth |
00039| |-----|----------------|-------------|-------------------|
00040| | **CFC 1000** | 1000 Hz (1650 Hz) | Head acceleration | Head impacts are high-frequency events |
00041| | **CFC 600** | 600 Hz (1000 Hz) | Chest, pelvis acceleration | Torso response is lower frequency |
00042| | **CFC 180** | 180 Hz (300 Hz) | Structural measurements | Vehicle deformation |
00043| | **CFC 60** | 60 Hz (100 Hz) | Sled displacement | Gross motion |
00044| 
00045| **Note:** The -3dB point is where signal is attenuated by 3dB (70.7%). The values in parentheses are the frequency at which attenuation reaches -40dB.
00046| 
00047| ### Filter Characteristics
00048| 
00049| SAE J211 specifies a **4th-order Butterworth low-pass filter** with specific characteristics:
00050| 
00051| | Parameter | Specification |
00052| |-----------|---------------|
00053| | Filter type | Butterworth (maximally flat) |
00054| | Filter order | 4th order (24 dB/octave rolloff) |
00055| | Phase | Zero phase shift (bi-directional filtering) |
00056| | Passband | Flat to -0.5 dB at CFC frequency |
00057| | Stopband | -24 dB at 1.67 × CFC frequency |
00058| 
00059| ### Sampling Requirements
00060| 
00061| | CFC | Minimum Sample Rate | Recommended Rate |
00062| |-----|---------------------|------------------|
00063| | CFC 1000 | 8,000 Hz | 10,000+ Hz |
00064| | CFC 600 | 4,800 Hz | 6,000+ Hz |
00065| | CFC 180 | 1,440 Hz | 2,000+ Hz |
00066| | CFC 60 | 480 Hz | 1,000+ Hz |
00067| 
00068| **Rule of thumb:** Sample at 8-10× the CFC frequency for adequate resolution.
00069| 
00070| ### Transducer Requirements
00071| 
00072| | Parameter | Specification |
00073| |-----------|---------------|

00076| | Zero shift (post-impact) | <2% of full scale |
00077| | Frequency response | Flat to at least CFC frequency |
00078| 
00079| ### Data Channel Designation
00080| 
00081| J211 defines a naming convention for data channels:
00082| 
00083| ```
00084| [Location][Direction][Type][Filter]
00085| 
00086| Example: 11HEAD0000ACXC (Head X-acceleration, CFC 1000)
00087| ```
00088|

## Questions Before Execution

1. **Story selection:** Are these 6 stories good, or would you prefer to swap any? The Stapp/Human Tolerance story is less of a "tragedy" but provides the scientific foundation for everything else.

2. **Technical depth:** For the "Technical Deep Dive" sections, should I include:
   - Full injury criteria formulas (HIC, SI, Nij)?
   - SAE J211 CFC filter classes?
   - Data channel counts per dummy?
   - (I'm leaning yes to all, given you said we can dive into specs)

3. **DTS product specificity:** How specific should I be about DTS products? I can reference:
   - Generic: "DTS accelerometers and data acquisition systems"
   - Branded: "SLICE Nano, SLICE6, TDAS Pro" (if you confirm product names)
   - Let me know if there are specific products to highlight

4. **Images:** Should I research and describe specific images to include (crash photos, dummy images, data traces), or use existing assets folder?

5. **Timing:** Is ~60-75 minutes acceptable, or should I trim to 6 shorter stories or 5 stories?

---

Ready to proceed when you confirm!

---

## User

1. Please add "Actress Jayne Mansfield Decapitated". It's ok if it's too long.
2. Formulas as decoration but not necessary to dive in. Reference CFC but no deep dive. Yes data channel counts.
3. Branded when known, generic is ok.
4. Research but feel free to reference assets/
5. Please disregard time limitations. try to keep each story interesting, not necessarily rehashing each spec each time. For instance, in one we can introduce the idea of CFC, in the next we can talk about HIC or another injury criteria, etc.

---

## Assistant (Plan · claude-opus-4-5 · 88.2s)

Excellent direction! I'll add the Mansfield story and vary the technical focus across stories to keep each one fresh. Let me finalize the plan:

---

# FINAL PLAN: "From Headlines to Hardware"
## How Tragedies Became Test Standards — And How We Measure Them

---

## 7 Stories with Varied Technical Focus

Each story will introduce a **different technical concept** to avoid repetition:

| Story | Headline | Test Mode | Technical Focus |
|-------|----------|-----------|-----------------|
| 1 | Airbag Kills Child | FMVSS 208 OOP | **Channel counts & dummy sizes** (CRABI, 5th female) |
| 2 | Actress Decapitated | FMVSS 223/224 Underride | **Force measurement** (load cells, deflection limits) |
| 3 | Luxury Cars Fail | IIHS Small Overlap | **Injury criteria: HIC** (formula as decoration) |

---

## Story-by-Story Detail

### STORY 1: "Airbag Kills 6-Year-Old in Minor Fender-Bender"
**→ FMVSS 208 Out-of-Position Testing**

**Technical Focus:** Dummy sizes, channel counts, compact instrumentation

| Section | Content |
|---------|---------|
| **Headline** | 175+ deaths 1990-1997 — children, small women. Airbags deploying at 200 mph. |
| **Unravel** | First-gen airbags designed for unbelted 50th percentile male. Anyone smaller or closer was at risk. |
| **Test Mode** | FMVSS 208 Out-of-Position: 6 static positions with CRABI infant, HIII 3YO, HIII 6YO, HIII 5th female |
| **Technical** | Introduce dummy family: CRABI 6-month (7.8 kg), HIII 5th female (49 kg). Channel counts: CRABI ~15 channels, 5th female ~47 channels. Neck tension limits. |
| **DTS** | SLICE Nano/Micro for infant dummies (smallest footprint). Challenge: fitting 15+ channels in a 7.8 kg dummy. Triaxial accelerometers, neck load cells. |
| **Forward** | Occupant classification validation, integration with cabin monitoring cameras. *(Speaker notes: DTS opportunity in real-time OCS validation systems)* |

**Images:** CRABI dummy photo (assets/), airbag deployment sequence, OOP test positions

---

### STORY 2: "Actress Jayne Mansfield Decapitated"
**→ FMVSS 223/224 Rear Underride Guards**

**Technical Focus:** Force measurement, load cells, deflection limits

| Section | Content |
|---------|---------|
| **Headline** | June 29, 1967 — Jayne Mansfield killed when car passed under semi-trailer. Three-year-old Mariska Hargitay survived in back seat. |
| **Unravel** | No protection against underride. Car roof sheared off. 300-500 Americans still die annually in underride crashes. |
| **Test Mode** | FMVSS 223/224: Rear underride guard requirements. Guards must resist specified forces without excessive deflection. |
| **Technical** | Force measurement fundamentals. Load cells: piezoelectric vs. strain gauge. Test: 50,000 lb (222 kN) applied at corner points. Deflection limit: ≤125 mm. IIHS has stricter test at 50% overlap. |
| **DTS** | High-capacity load cells, displacement transducers. Not a dummy test — barrier/guard instrumentation. Static test requires precise force application measurement. |
| **Forward** | Side underride protection (not yet mandated). Active systems that deploy protective structures. *(Speaker notes: DTS opportunity in active underride system validation)* |

**Images:** Vintage truck guards, IIHS underride test photo, force diagram

---

### STORY 3: "BMW, Mercedes, Audi Fail New Crash Test"
**→ IIHS Small Overlap Frontal**

**Technical Focus:** Head Injury Criterion (HIC) — the math behind the number

| Section | Content |
|---------|---------|
| **Headline** | 2012: Luxury brands rated Marginal/Poor. Only 3 of 13 midsize cars earned "Good." |
| **Unravel** | 40% overlap test had been "solved." Real-world crashes were 25% overlap into poles/trees. Structure bypassed main rails. |
| **Test Mode** | IIHS Small Overlap: 25% rigid barrier, 40 mph, driver side |
| **Technical** | Introduce HIC formula (decorative). HIC₁₅ ≤700 limit. What it means: acceleration integrated over time, raised to 2.5 power. Why 15ms window matters. Also: femur load ≤10 kN, tibia index, structural intrusion. |
| **DTS** | THOR-M dummy (150+ channels vs. Hybrid III's 47). Lower leg load cells critical for this test. Triaxial head accelerometer (CFC 1000 — brief mention, deeper in Story 5). |
| **Forward** | Passenger-side small overlap (added 2017), far-side impact, oblique crash modes. *(Speaker notes: THOR-M adoption drives DTS channel density requirements)* |

**Images:** Small overlap crash photo (assets/iihs_small_overlap.jpg), structural intrusion comparison, HIC formula graphic

---

### STORY 4: "32 High School Players Dead From Head Injuries"
**→ NOCSAE Drop Test & Linear Impactor**

**Technical Focus:** Severity Index (SI) — the helmet metric

| Section | Content |
|---------|---------|
| **Headline** | 1960s-70s: 32 deaths/year. Helmets existed but weren't tested. No standard. |
| **Unravel** | NOCSAE formed 1969. Built drop towers. Tested every helmet. Many failed catastrophically. |
| **Test Mode** | NOCSAE drop test: Helmeted headform dropped from 60" onto various anvils. SI must be <1200. Linear impactor added 2016 for rotational metrics. |
| **Technical** | Introduce SI formula (decorative): SI = ∫a²·⁵ dt. SI <1200 threshold. Difference from HIC: SI is raw integral, HIC normalizes by time. Why 2.5 exponent? Correlates with brain injury risk. Drop heights, anvil types. |
| **DTS** | Headform accelerometers (triaxial + angular). 6DOF sensors for rotational acceleration (new frontier). High sample rate: 100 kHz+ for impact events. SLICE6 for angular rate. |
| **Forward** | Sub-concussive tracking, cumulative exposure. In-helmet sensors for game-day monitoring. *(Speaker notes: DTS opportunity in consumer-grade in-helmet monitoring — SLICE Nano integration)* |

**Images:** Drop tower setup, football helmet cross-section, SI calculation diagram

---

### STORY 5: "The Fastest Man on Earth Survived What Should Have Killed Him"
**→ Human Tolerance Research & CFC Filtering**

**Technical Focus:** Channel Frequency Classes (CFC) — why we filter data

| Section | Content |
|---------|---------|
| **Headline** | December 10, 1954: Col. John Paul Stapp hits 632 mph, decelerates to zero in 1.4 seconds. 46.2g sustained. "Fatal" threshold was 18g. |
| **Unravel** | Aviation medicine had no data — only assumptions. Stapp tested on himself. Proved humans can survive far more than believed. |
| **Test Mode** | Not a regulation — but the FOUNDATION of all crash testing. Wayne State Tolerance Curve → HIC. Acceleration-duration relationships. |
| **Technical** | **CFC Deep Dive**: Why raw accelerometer data is unusable. High-frequency noise (structural resonance, electrical interference). SAE J211 defines CFC 1000 (head), CFC 600 (chest), CFC 180 (structure). 4th-order Butterworth filter. What happens without proper filtering: garbage data, wrong conclusions. |
| **DTS** | Every DTS DAQ system implements J211 filtering. Hardware anti-aliasing + software post-processing. Calibration to J211 specs. Sample rates: 10 kHz minimum for CFC 1000. |
| **Forward** | Female-specific tolerance data (THOR-5F released 2023). Elderly occupant protection — age-adjusted criteria. *(Speaker notes: Stapp's legacy is the scientific method applied to safety — DTS continues this with calibration standards)* |

**Images:** Stapp rocket sled photo (assets/), raw vs. filtered data trace comparison, CFC frequency response curves

---

### STORY 6: "Four NASCAR Champions Dead in Eight Months"
**→ HANS Device & SAFER Barrier**

**Technical Focus:** Neck injury measurement (Nij, 6-axis load cells)

| Section | Content |
|---------|---------|
| **Headline** | May 2000 – Feb 2001: Adam Petty, Kenny Irwin Jr., Tony Roper, Dale Earnhardt. All basilar skull fractures. Same injury, same cause. |
| **Unravel** | High speeds + concrete walls + unrestrained heads = catastrophic neck loads. Earnhardt called HANS "that damn noose" — refused to wear one. |
| **Test Mode** | HANS device mandated Oct 2001. SAFER barriers (Steel And Foam Energy Reduction) at all ovals by 2006. |
| **Technical** | **Neck Injury Deep Dive**: Nij formula (decorative). Combines axial load + bending moment. Critical values: 6,806 N tension, 310 Nm flexion. HANS reduces neck tension from 740 lb to 210 lb — 72% reduction. 6-axis neck load cell: measures Fx, Fy, Fz, Mx, My, Mz simultaneously. |
| **DTS** | 6-axis upper neck load cell (6 channels). Lower neck load cell (6 more channels). High-rate sampling for impact events. SAFER barrier instrumentation: load cells within barrier structure measure energy absorption. |
| **Forward** | Closed-wheel vs. open-wheel protocols. Halo/Aeroscreen integration. Secondary impact protection. *(Speaker notes: DTS barrier instrumentation opportunity — real-time energy absorption measurement for barrier development)* |

**Images:** Earnhardt crash photo (if appropriate), HANS device diagram, SAFER barrier cross-section, 6-axis load cell schematic

---

### STORY 7: "Soldiers Surviving Blasts, But Never Walking Again"
**→ WIAMan Underbody Blast Testing**

**Technical Focus:** High-rate data acquisition (100 kHz+), DTS partnership

| Section | Content |
|---------|---------|
| **Headline** | Iraq/Afghanistan: Thousands of spinal injuries from IED underbody blasts. Soldiers survived but with devastating injuries. |
| **Unravel** | Automotive dummies measure horizontal crash. IED blast is vertical — floor accelerates up into occupant's spine. Different injury mechanism entirely. |
| **Test Mode** | WIAMan (Warrior Injury Assessment Manikin). MIL-STD testing protocols. Underbody blast simulation. |
| **Technical** | **High-Rate DAQ**: Blast events are 10× faster than car crashes. Requires 100 kHz+ sample rates (vs. 10 kHz automotive). DRI (Dynamic Response Index) for spinal injury. Lumbar compression limits. Pelvis acceleration. 2000g+ accelerometer range (vs. 500g automotive). |
| **DTS** | **DTS partnered with US Army to develop WIAMan instrumentation.** SLICE systems embedded in dummy. Lumbar spine load cells. High-g triaxial accelerometers. Real partnership example: DTS engineering directly contributing to military safety. |
| **Forward** | Full-body blast effects. Repeated sub-injury exposure tracking. Helmet/body armor integration testing. *(Speaker notes: WIAMan represents DTS's ability to develop custom solutions for emerging threats — same capability applies to EV battery testing, autonomous vehicle validation, etc.)* |

**Images:** WIAMan dummy (assets/wiaman_dummy.jpg), underbody blast diagram, high-rate data trace, MRAP vehicle

## Ready to Execute

When you give the go-ahead, I will:

1. Create the folder `From_Headlines_to_Hardware/`
2. Write the full `script_and_speaker_notes.md` (~1,500-2,000 lines)
3. Create `create_presentation.py` to generate the PowerPoint
4. Generate `From_Headlines_to_Hardware.pptx` with embedded speaker notes
5. Run the embed script to add notes directly into the PowerPoint

Estimated time: This is a substantial document. I'll work through it systematically.

**Shall I proceed?**

---

## User

Do you recommend using the "Build" agent rather than "Plan" to execute this plan?

---

## Assistant (Plan · claude-opus-4-5 · 8.2s)

Yes, I recommend switching to **Build mode** to execute this plan. Here's why:

## Why Build Mode is Appropriate Now

1. **Plan is complete and approved** — We've defined all 7 stories, the technical focus for each, the deliverable files, and the structure.

2. **No open questions remain** — You've answered all my clarifying questions (story selection, technical depth, DTS branding, time constraints, varying content).

3. **Execution is straightforward** — The work is primarily writing markdown and Python, then running the generator script. No architectural decisions or exploration needed.

4. **Plan mode restrictions** — I'm currently in read-only mode and cannot create files, write content, or run scripts.

## What Build Mode Will Do

1. Create `From_Headlines_to_Hardware/` folder
2. Write `script_and_speaker_notes.md` (~1,500-2,000 lines covering all 7 stories)

`tool_use` ids were found without `tool_result` blocks immediately after: toolu_01C9yusFx97nP91AsWzSsneE. Each `tool_use` block must have a corresponding `tool_result` block in the next message.
