Systems and methods of communications for weapon detection systems
First Claim
1. A method of processing communications associated with detection of acoustic events, the method comprising:
- processing communications associated with sensors deployed across an area to be monitored, wherein the sensors are interconnected via a network operating, at least in part, using wireless communications that include accessing the network through a cellular telephone network, and wherein each sensor includes a clock source and a microphone for detecting an acoustic event;
processing signals communicated over the network from each sensor that detects the acoustic event, wherein the signals include times of arrival as to when the acoustic event was detected at the sensors, with each time of arrival being obtained from the clock source associated with the sensor that detected the acoustic event;
determining a location of a source of the acoustic event as a function of the time of arrival information and sensor location data; and
accumulating statistical information regarding the acoustic event from sensors registering the acoustic event and scoring the acoustic event as a function of the statistical information.

Abstract
Systems and methods are disclosed for data processing associated with acoustic events such as weapon fire. In one exemplary implementation, there is provided a method of processing communications associated with identifying or locating a weapon fire event. Moreover, the method may include processing communications from a plurality of sensors deployed across an area to be monitored, wherein the sensors are interconnected via a wireless network, processing signals communicated over the network from each sensor that detects the acoustic event, and determining a location of a source of the acoustic event as a function of time of arrival information and sensor location information. Other exemplary implementations may include using time of arrival data that is synchronous/universal among the sensors.
