TECHNOLOGY ENGINEERED FOR THE FIELD
Small device.
Massive impact.
Pocket-sized and one-button simple on the outside. Inside: infrared optics, a dedicated processor, and an algorithm built for one job — an objective answer, every time.
Built for real world conditions.
Infrared imaging
A near-infrared camera captures the pupil clearly in any ambient light — bright roadside, darkened room, or helicopter cabin.
PLR-3 algorithm
LIOR’s pupil light reflex algorithm analyzes constriction speed, amplitude, and latency to produce an objective reactivity score.
Guided alignment
Sights and a red focus ring around the lens make correct positioning intuitive, improving accuracy and reducing rejected readings.
Distance-independent scaling
PCT-filed, patent pending. Pupil size is measured accurately without fixed distance or positioning hardware.
Private by design
All processing happens on the device. Results are not stored beyond the reading — patient privacy is protected by architecture.
Flashlight mode
A toggle switch converts LIOR into a standard examination light, so one device covers the whole assessment workflow.
INSIDE LIOR
Purpose built. Field ready.
Every component serves the same goal: a fast, objective, field-ready pupil assessment. Infrared camera, LED array, custom PCB, and rechargeable battery fit into a pocket-sized enclosure — no smartphone, no cloud dependency, no consumables.
- Dedicated IR camera and MCU for on-device processing
- Rechargeable battery with up to an estimated 8 days of typical use
- Integrated flashlight mode for the full clinical workflow
DESIGN EVOLUTION
From first sketch to field-ready.
LIOR began as a simple idea: bring the objectivity of a hospital pupilometer into a penlight-sized tool that works in the back of an ambulance. Every iteration since has been driven by the same constraint — it has to be simple enough to use with gloves on, in the dark, under pressure.
