Someone Is Using Their Head

North Carolina is one of three universities, along with Virginia Tech and Oklahoma, using the Head Impact Telemetry system to study concussions. The system works like this: Six tiny sensor chips are embedded in the padding of a helmet. They measure the acceleration and deceleration of the head to determine the location and magnitude of any impact. A small radio imbedded in the helmet sends the information to a sideline unit, where a laptop computer analyzes and saves the data.
