Claim 0:
1. A method for determining an operational status of a firearm based on a discharge event, the method comprising:
receiving, by an event detection module, a signal indicative of a plurality of accelerations sensed by at least one inertial measurement unit (IMU);
determining a sample shot profile based on the signal, the sample shot profile comprising:
a first peak at a first time representing initial discharge of the firearm wherein a bolt of the firearm moves from an initial forward position;
a second peak at a second time, subsequent to the first time, representing the bolt engaging a rear buffer of the firearm;
a third peak at a third time, subsequent to the second time, representing the bolt returning to the forward position;

determining a measured bolt speed of the weapon based on a difference between the second and third times;
comparing the measured bolt speed to a baseline weapon bolt speed; and
determining an operational status of the weapon based on the comparing.
