The Linx IAS is a gadget, developed by BlackBox Biometrics and unveiled at CES 2015, that uses impact assessment sensors to identify sports concussions. The short-term and long-term impact of concussions and head injuries on players has received a great deal of attention particularly in the world of NFL.
The Linx IAS uses an accelerometer and gyroscope to measure forces on the user's head. The gadget can simply be slid into a skull cap or headband and is suitable for both warm or cold weather.
It sends data via Bluetooth Smart to an accompanying smartphone app, where the athlete or athlete's manager can analyze pertinent data. The device sends an alert whenever a concussion-level impact occurs, so players or their coaches can take action rightaway.
