“Hothead Technologies in Atlanta is introducing a helmet that monitors the temperatures of an entire football team in real time so coaches can pull players off the field before it's too late. The Heat Observation Technology (HOT) system uses an electric thermometer called a thermistor, a spoon-size device made of metals whose electrical resistance vary with temperature. Inserted under the padding of a standard helmet, the thermistor measures the temperature in the player's temporal artery and uses a built-in radio to transmit temperatures between 99.9° and 110°F — heat illness typically sets in around 104° — every 10 seconds to a PDA monitored by a coach or trainer on the sidelines. Rain, sweat and ambient temperature typically skew the results from skin-contact thermometers, but Hothead is nearly as accurate as a rectal thermometer, which sets the standard for the industry.”

Nice technology, We have been playing with regular helmets for as long as Football had been professionally regulated and seldom have you seen players beeing injured by heat.
