HIRTS-1 is a A compact,self-contained recording device that measures and records impacts and impacts to helmets or other space-constrained devices. The device is implanted or mounted on the inner surface of the helmet. The device contains three accelerometer sensors that accurately measure the acceleration (force) of the helmet during impact in three directions. The device can therefore measure and record impacts from any direction and at any time. During an impact event,the device measures and records the peak or maximum acceleration (force) of the event in each of the three axes (x,y,and z),as well as the exact date and time of occurrence. Additionally,the device measures and records the velocity changes (proportional to energy) associated with impact acceleration events in each of the three axes (x,y,and z). HIRTS devices can take these measurements multiple times (up to thousands) in a row and can operate independently for up to several days. After the recording session (control test,exercise,or game) is completed,the device connects to the computer via wireless infrared in order to retrieve the recorded data. The data is displayed in a spreadsheet-like table listing all recorded events by number,date,time,peak g-force value,and delta-V energy value. These data can be used to assess the severity of an athlete's helmet impact and potentially be used to determine concussion severity for impacts with unusually high amplitude and energy. The device could also serve as a tool to identify serious impacts that may contribute to a concussion but may not be reported to the coaching staff by the athlete themselves.
