Carriage Life Monitoring Of External Stores

RNET and Purdue will develop an ultra-low power carriage life monitoring sensor for external stores. The system will use a minimal number of sensors (biaxial linear accelerometers and biaxial gyroscopes) and the power consumption will be optimized by incorporating innovative time and frequency domain event recognition algorithms. A biaxial AC couple accelerometer and a biaxial gyroscope will allow the identification of platform shutdown/start, steady state flight hours, maneuvering flight hours, count of adjacent store firings, onboard gunfire, and ballistic/fragment impacts. The two sensors can be trigger counters and data collectors that will enable the events to be identified offline. The system will be event driven, and not require a microprocessor for normal operation. Asynchronous processing triggers, including analog triggering sensors and wake-on-RF, will eliminate the need for synchronous networking or sensor processing. RNET will develop the required ASICs using ultra-low power techniques utilizing"independent double gate"(IDG) technology.
