Abstract: A device for collecting data on small-arms usage that senses when a shot has been fired from a gun using its acceleration, acoustic noise or RF emissions; measures the interval between shots so that the firing rate may be determined; measures the time at which each shot has been fired; measures the temperature of the barrel when each shot is fired; stores any combination of temperature, firing rate, firing intervals and time data for subsequent analysis and has an electrical interface to transfer data from the device to a computer or other data collection device.

Abstract: A system and method for collecting data on small-arms usage in the form of a device which is mounted to the firearm so as to be able to sense at least an impulse in the firearm due to firing. The device is mounted to the gun so as to detect impulses due to firing. A processor accepts impulse signals from the sensor, and uses either a hold-off delay or a windowing time to determine and store information related to the firing of the firearm. This information may be any combination of temperature, firing rate, firing intervals and time data for subsequent analysis, and, optionally, information identifying the weapon to which the device is attached. The device preferably has an interface to transfer data from the device to a computer or other data collection device.
