Claim 11:
12. A system for providing discharge monitoring of a firearm, the system comprising:
a sensor disposed on the firearm that senses (i) first, second and third accelerations and (ii) first second and third rotations, wherein the first, second and third accelerations are sensed along first, second and third axes, respectively and the first, second and third rotations are sensed around the first, second and third axes, respectively;
an event detection module that receives signals from the sensor indicative of the first, second and third accelerations, wherein the event detection module is configured to:
assign respective acceleration and rotation input signals to sample event candidates at respective windows of time;
compare the acceleration signals of the sampled event candidates to a discharge acceleration template that represents a confirmed weapon discharge event;
identify a subset of accepted accelerations from the sampled event candidates that satisfy the discharge acceleration template;
compare a first rotation input signal from the sample window of time associated with each accepted acceleration in the subset to a first rotation template that represents a confirmed weapon discharge event; and
determine whether the sampled event candidate is a discharge event based on satisfying both the discharge acceleration template and the first rotation template.
