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.

Claims

1-52. -52. (canceled)

53. A weapon fire processing/location system comprising:

an array of sensors, at least one sensor of the array of sensors comprises;

a microphone for receiving acoustic signals;

a processor for processing received acoustic signals to detect an acoustic event;

a display associated with the at least one sensor;

a GPS receiver for determining a sensor position; and

a processing, client or server component in communication with the processor, wherein the processor, client or server component processes information related to the acoustic event and communicates with a external component regarding the information.

54. The system of claim 53, wherein the system is part of a client-server system.

55. The system of claim 53, wherein the at least one sensor comprises a transceiver for receiving and transmitting data.

56. The system of claim 55, wherein the transceiver transmits data to a center that processes commands associated with the gunshot.

57. The system of claim 53, wherein the information related to the acoustic event includes an azimuth to a source location of the weapon fire.
