Head impact telemetry system

Head Impact Telemetry System (HITS) is a hardware and software system intended as a shock detector and logger; the hardware is embedded in football helmets and transmits data to a computer.^[1]

The system was developed by Simbex, based on Lebanon, New Hampshire, in collaboration with Virginia Tech,^[1] starting around 2000.^[2] By 2006 the system weighed about six ounces and had six sensors, a small computer, a battery and a radio; helmets including the system were marketed by Riddell and a set of 40 cost around $50,000 at that time.^[2] At that time nine NCAA football teams and a high school team were testing it, and the NFL had decided it not well validated enough to use.^[2]
