Weapon usage monitoring system having a signal processing module that determines a discharge event

A system for providing discharge monitoring of a firearm, the system comprising:

• an event detection module having at least one sensor that senses an acceleration and generates an acceleration signal, wherein the sensor comprises:
• a first inertial measurement unit (IMU) configured for a first gravity sensitivity and that measures a first acceleration;
• and
• a second IMU configured for a second gravity sensitivity and that measures a second acceleration, the first and second gravity sensitivities being distinct;
• and
• a signal processing module that receives the acceleration signal, the signal processing module configured to determine whether the acceleration signal is a discharge event and generate an event detection signal based on the determination, the signal processing module further configured to maintain a shot count of the firearm based on the determination that the event detection signal is a discharge event, wherein the signal processing module compares the first and second accelerations to a shot detection threshold acceleration and wherein the event detection signal is further based on both of the first and second accelerations satisfying the shot detection threshold.
