Claim 15:
16. An apparatus comprising:
memory containing a data signature defining a threshold for an axis or defining multiple thresholds for multiple respective axes, wherein the data signature represents motion of the apparatus that is expected in response to firing a projectile;
a sensor configured to measure motion along multiple axes and generate an output indicating the measured motion of the apparatus; and
a processor configured to:
generate an indication of a gun event based on comparing the output of the sensor to the data signature and determining that the measured motion of the apparatus matches motion of the apparatus that is expected in response to a gunshot, and
update, based on the indication of the gun event, a data structure stored in the memory that indicates a number of rounds remaining or a number of rounds that have been fired.
