US12578158 - Systems and techniques for identifying gun events

The present disclosure provides systems and techniques for identifying gun events. A gun event may include a nominal event, such as the discharging of a projectile or the ejecting of a cartridge shell, or an anomalous event, such as a misfire or a failure to feed. An apparatus may include a sensor that measures motion of a gun along multiple axes. The apparatus may identify a gun event based on the measured motion of the gun satisfying a motion condition. The motion condition may include an acceleration threshold value, and the measured motion of the gun may satisfy the motion condition based on a measured acceleration value exceeding the threshold acceleration value. The apparatus may transmit an electrical signal based on the measured motion of the gun satisfying the motion condition. The electrical signal may reset a charging circuit, increment a shot count, or decrement a round count.

The patent describes a system for identifying gun events, including both normal discharges and misfires, by measuring motion through a multi-axis sensor. It details a method for analyzing acceleration data to determine if a firing event occurred as intended, storing misfire indications, and providing alerts for malfunctions.

Claim 1

1 . A method performed by a gun, the method comprising: identifying a firing event that is intended to cause the gun to fire; measuring, at a sensor of the gun, acceleration data along multiple axes, wherein the acceleration data is collected in a buffer of the gun for a predetermined amount of time; analyzing the acceleration data to determine whether an acceleration threshold is satisfied during the predetermined amount of time subsequent to the firing event, wherein the acceleration threshold represents a nominal discharge of a projectile from the gun; identifying a misfire event based on the acceleration threshold not being satisfied during the predetermined amount of time subsequent to the firing event; storing an indication of the misfire event in non-volatile memory of the gun, wherein the indication of the misfire event includes the acceleration data and a timestamp indicating an approximate time at which the misfire event occurred; and displaying, in response to the misfire event, an alert indicating that a malfunction has occurred. identifying a firing event that is intended to cause the gun to fire; measuring, at a sensor of the gun, acceleration data along multiple axes, wherein the acceleration data is collected in a buffer of the gun for a predetermined amount of time; analyzing the acceleration data to determine whether an acceleration threshold is satisfied during the predetermined amount of time subsequent to the firing event, wherein the acceleration threshold represents a nominal discharge of a projectile from the gun; identifying a misfire event based on the acceleration threshold not being satisfied during the predetermined amount of time subsequent to the firing event; storing an indication of the misfire event in non-volatile memory of the gun, wherein the indication of the misfire event includes the acceleration data and a timestamp indicating an approximate time at which the misfire event occurred; and displaying, in response to the misfire event, an alert indicating that a malfunction has occurred.
