System and Method For Detecting and Analyzing Near Range Weapon Fire

摘要

A method for identifying a gunshot occurrence. According to one embodiment, microphone data and inertial motion data are acquired with a hand-held device. Based on an acoustic criterion, a determination is made as to whether a gunshot has been produced. Based on a correlation criterion applied to the inertial motion data, a determination is made as to whether the gunshot was produced from fire produced by a first person having physical possession of the hand-held device or by a second person spaced away from the first person.

主权项

1. A computer-implemented method for monitoring whether a person in possession of a first hand-held communications device is in the presence of weapon fire, comprising:
receiving, into a non-transitory computer readable storage medium, via a wireless network, information derived from measured acoustic data acquired with a microphone connected to the first hand-held device, the information useful for providing an indication of whether an acoustic event is the result of weapon fire within ten meters of the hand-held device.
