* TCCC — Tactical Combat Casualty Care: the U.S. military standard for point-of-injury emergency medicine.

01 — Problem

Emergencies don't wait
for a trained medic.

Most casualties in the field — military or civilian — are treated by someone with no medical training. Even trained medics lose protocol recall under extreme stress. The result: wrong decisions, missed steps, preventable deaths.

Most emergencies happen without a medic present

Car accidents, aviation incidents, maritime emergencies, wilderness — the first person on scene is almost never a trained medical professional.

Even trained medics fail under extreme stress

Cognitive load, darkness, noise, and time pressure degrade protocol recall exactly when correct execution is life-critical.

No offline AI guidance tool exists

Current field aids are static PDFs and laminated cards. No system provides interactive, verified, voice-accessible guidance without a network.

02 — Solution

PAL: a pocket-sized AI
that never loses signal.

PAL runs entirely on-device. Ask a clinical question by voice or text — get a verified, source-cited protocol response in seconds. No internet. No cloud. No latency.

🎙️

Hands-free voice guidance

Ask a question by voice — PAL speaks the answer back. Both hands stay on the patient.

🚑

Auto EVAC priority

PAL tracks vitals, injuries, and time — and calculates evacuation priority in real time: URGENT / PRIORITY / ROUTINE.

📋

TCCC card — auto-filled

Tourniquet times, medications, mechanism of injury, vitals — DD1380 fills itself as the session progresses.

⏱️

Tourniquet timer

Marks application time automatically. Voice alerts at 60 and 90 minutes. Critical detail that's easy to miss under fire.

🛡️

Never guesses

Low-confidence queries return "not found" — not a fabricated answer. PAL stays silent rather than risk a wrong protocol.

📡

Works anywhere

GPS-denied, signal-blocked, jammed, underground, offshore — PAL operates where no cloud-based tool can.

03 — Hardware & Stack

Prototype.

Raspberry Pi 5 — quad-core ARM Cortex-A76 @ 2.4GHz, 8GB RAM. Powered by PiSugar 5000mAh battery with wireless charging. In the prototype, an iPhone acts as the screen, mic, and speaker — by design. No custom silicon required.

04 — Performance

Tested against 10 clinical scenarios.
Zero fabricated answers.

Every test case drawn from real field scenarios. Validated against CoTCCC 2024 and JTS CPG protocols. When PAL doesn't know — it says so.

05 — Strategic Fit

Built for those who
can't afford to fail.

PAL maps directly to six key DoD medical AI priorities — offline operation, point-of-injury support, automated documentation, voice interface, zero hallucination, and pocket form factor.

✓

Offline AI for denied environments — zero network dependency, GPS-blocked, jammed — PAL operates where no other AI system can.
✓

Point-of-injury decision support — verified TCCC protocol delivery at the moment of casualty, not at Role 2 or higher.
✓

Automated TCCC documentation — DD1380 auto-filled in real time, reducing documentation burden under fire.
✓

Voice-accessible interface — hands-free operation, critical when the medic's hands are occupied treating a casualty.
✓

Zero hallucination policy — low-confidence queries return "not found" rather than fabricated guidance. Clinical safety is non-negotiable.
✓

Pocket form factor — fits in a standard aid bag. No additional equipment. Deployable anywhere a medic goes.
