Head Impact Telemetry System What if it were possible to detect concussion-inducing trauma at the moment of impact? That's the premise behind the Head Impact Telemetry System (HITS) developed by Simbex. The system (not shown) was designed for use in both sport and military helmets. As soon as the helmet is hit, sensors record information about the blow and transmit that data to a remote computer terminal. Data collected with this kind of system also helps scientists understand how varying forces contribute to traumatic brain injuries.
