Brain Sentry: brain injury-detection hardware for football helmets [VIDEO]

Imagine if football coaches, especially coaches for leagues where the players are 14 years and under, could detect when a player took a particularly painful hit to the head thanks to a light-up sensor on the back of the helmet.
Now imagine a football coach told you there was “no f-ing way” he would put a sensor on the helmet. “What happens if it’s third down and two yards to go, and a kid’s light comes on?” he asks you.
That’s exactly what happened to Greg Merrill, the founder of Bethesda-based Brain Sentry, which does exactly that: makes helmet-mounted impact sensors that light up when a football player takes an unusually damaging hit (at least, for the game of football).
