Hothead Technologies for Football Helmets

A broken leg can end a football player’s season, but overheating can end his life. A Hothead helmet will get football players off the field before heat stroke sets in, a problem that’s killed 39 players since 1995. Every 10 seconds, a thermometer inside measures skin temperature near the player’s temporal artery and transmits it to a PDA monitored by a trainer on the sidelines. An alarm sounds if the player’s temperature crosses 102.5ºF to ensure that the coaches get to the player before he reaches 104º, the point where organ systems begin to fail and it becomes more difficult to revive the athlete.
