System For Effective Control Of Urban Environment Security

US Patent:
5504717, Apr 2, 1996
Filed:
May 27, 1994
Appl. No.:
8/250743
Inventors:
J. Brian Sharkey - Alexandria VA
Randy A. Doblar - Alexandria VA
Frank E. Bothwell - Falls Church VA
Ronald A. Belt - Plymouth MN
Edward A. Page - Kensington MD
Assignee:
Alliant Techsystems Inc. - Hopkins MN
International Classification:
G01S 380
US Classification:
367124
Abstract:
A security system for detecting and reporting gunshot events for control of urban environment security which includes a communication link coupled to a plurality of pole units arranged in a dense grid. Each of the plurality of pole units includes a microphone, a data acquisition unit coupled to said microphone, a signal processor for discriminating gunshot events, and a communication interface apparatus coupled at an input to the signal processor. The communication interface also has an output coupled to the communication link, where the communication interface transmits and receives data on the communication link. A central processor is coupled to the communication link so as to receive data from and transmit data to the plurality of pole units. The central processor and the plurality of pole units operate so as to detect and locate gunshot events sensed by one or more of the plurality of pole units.

System For Effective Control Of Urban Environment Security

US Patent:
5703835, Dec 30, 1997
Filed:
Apr 1, 1996
Appl. No.:
8/627323
Inventors:
J. Brian Sharkey - Alexandria VA
Randy A. Doblar - Alexandria VA
Frank E. Bothwell - Falls Church VA
Ronald A. Belt - Plymouth MN
Edward A. Page - Kensington MD
Assignee:
Alliant Techsystems Inc. - Hopkins MN
International Classification:
G01S 380
US Classification:
367124
Abstract:
A security system for detecting a gunshot event. A communication link, and a number of pole units are arranged in a dense grid. Each one of the pole units includes a microphone and a signal conditioning and thresholding unit coupled to the microphone. The signal conditioning and thresholding unit outputs a detection signal in response to an event when an output signal from the microphone exceeds a peak background average. A data acquisition and signal processing unit is coupled to the signal conditioning and thresholding unit for discriminating gunshot events. The data acquisition and signal processing unit remains in a powered down stand-by mode so as to conserve energy until a detection signal is received. The data acquisition and signal processing unit includes apparatus for identifying a gunshot event by measuring an initial pulse time duration and subsequent pulse pattern features, and a communication interface coupled at an input to the data acquisition and signal processing unit. A central processor is coupled to the communication link so as to receive data from the pole units where the central processor and the pole units operate so as to detect and locate gunshot events sensed by one or more of the pole units.
