Gunshot detection sensor with display
First Claim
1. A gunshot location system comprising:
- an array of acoustic sensors, at least one sensor of said array of sensors comprises;
a microphone for receiving acoustic signals;
a processor for processing received acoustic signals to detect an acoustic event;
a GPS receiver for determining a sensor position; and
a first network interface;
a display associated with said at least one sensor and in communication with at least one sensor, said display comprising;
a graphic device for displaying information to a user; and
an electronically readable compass for determining a heading of the user; and
a server in communication with said first network interface wherein, when said acoustic sensor detects an acoustic event, said sensor position is transmitted to said server through said first network interface and when a plurality of sensors report said acoustic event, said server determines a source location for said acoustic event and transmits said source location to said sensor through said first network interface and said acoustic sensor communicates range and bearing information to said display.

Abstract
A system for locating and identifying an acoustic event such as gunfire. The inventive system employs a plurality of man wearable acoustic sensors for detecting gunfire, each acoustic sensor having a display associated therewith for displaying information concerning the acoustic event to a user. In preferred embodiments, the sensor includes a microphone for receiving acoustic information; an A/D converter; a processor for processing the digitized signal to detect a gunshot and determine a time of arrival; a GPS receiver for determining the position of the acoustic sensor; and a network interface for bidirectional communication with a system server. Preferably the display comprises: an LCD; and an electronically readable compass. When the display and acoustic sensor are in separate housings, the acoustic sensor includes a transmitter and the display includes a receiver for transferring the gunshot information.
