US Patent 12007185 Weapon usage monitoring system having discharge event monitoring

A system and method for determining a discharge event of a firearm includes receiving, by an event detection module, acceleration input signals and rotation input signals. An acceleration vector magnitude is calculated from the acceleration signals. The acceleration vector magnitude is compared to a threshold acceleration. A sample event candidate is assigned to the acceleration vector magnitude based on the comparing. The sample event candidate comprises the acceleration input signals and the rotation input signals for a predetermined duration of time. The sample event candidate is received at a machine learning module. Characteristics of the discharge event detected are determined including ammunition type based on the acceleration and rotation input signals in the sample event candidate.
