A Heatstroke-Sensing Helmet

With the coming Training camps, this is a great idea.
Too bad 33 football players had to die before this was available.

Just in time to save some lives on football practice fields this summer, Hothead is a headband-like sensor fitted into helmets that transmits warnings to the coach's handheld device when players are getting dangerously overheated.

According to DVICE.com this will cost about $99 per player.

Sounds like an excellent investment.

There's been 33? Wow! Anything to prevent #34 though.

I gotta wonder though, when your out there in the heat, during a play, your body temperature will likely temporarally rise, and then settle back down after the plays done, might that go off prematurely?
