Wearable system for accelerometer-based detection and classification of firearm use
First Claim
1. A system for detecting and monitoring firearm use by an individual, the system comprising:
- a wearable gunshot detection device comprising an accelerometer, a buffer, and a memory; and
a remote monitoring system,wherein the wearable gunshot detection device is configured to be fastened to a wrist of the individual and is further configured to;
detect and measure, using the accelerometer, an acceleration corresponding to a movement of the wrist of the individual to which the gunshot detection device is fastened;
produce and store, in the buffer, acceleration data corresponding to the movement;
determine if the acceleration data includes a ballistic spike that tentatively corresponds to a gunshot fired by the individual;
if it is determined that the acceleration data includes the ballistic spike tentatively corresponding to the gunshot fired by the individual, transfer and store an amount of the acceleration data from the buffer to the memory;
determine if the amount of the acceleration data definitively corresponds to the gunshot fired by the individual, wherein the wearable gunshot detection device is further configured to;
determine and assign a first weight to a difference between a first acceleration detected during a time period preceding the ballistic spike and a second acceleration detected during a time period coinciding with the ballistic spike; and
during a time period following the ballistic spike, determine and assign a second weight to a peak value of a muzzle lift, and determine and assign a third weight to a recoil acceleration; and
if the amount of the acceleration data definitively corresponds to the gunshot fired by the individual, then transmit the amount of the acceleration data to the remote monitoring system.

Abstract
A system for detecting and classifying firearm use comprising is provided. The system includes a wearable gunshot detection device and a remote monitoring system. The wearable gunshot detection device is configured to detect an acceleration of an extremity of an individual to which the gunshot detection device is attached, determine acceleration data based on the detected acceleration, and determine whether the acceleration data corresponds to a gunshot fired by the individual to which the gunshot detection device is attached. If the acceleration data corresponds to a gunshot fired by the individual to which the gunshot detection device is attached, then the wearable gunshot detection device transmits the acceleration data to the remote monitoring system.
