System and method of automated gunshot emergency response system
First Claim
1. A threat sensing system comprising:
- at least one threat sensing device mounted inside a building, the at least one threat sensing device comprising plurality of sensors, the plurality of sensors comprising an acoustic sensor, a gas sensor, a pressure sensor, and a first communication device configured to output sensor data along a communication pathway; and
a system gateway, comprising a second communication device configured to receive sensor data from the at least one threat sensing device along the communication pathway, the system gateway being configured to automatically communicate at least one of the existence of the threat, the sensor data, or one or more predetermined messages to a plurality of pre-registered recipient devices by processing a probability to give a confidence score based upon a sequence of the sensor data from the acoustic sensor, the pressure sensor, and the gas sensor that is determined to correspond to one of a predetermined plurality of known threats;
when the confidence score is low, do nothing;
when the confidence score is medium, record data in a memory;
when the confidence score is high, automatically communicate the at least one of the existence of the threat, the sensor data, or one or more predetermined messages to the plurality of pre-registered recipient devices.

Abstract
A threat sensing system is provided including, in some aspects, a plurality of threat sensing devices distributed throughout a school or facility, with each of the threat sensing devices comprising one or more acoustic sensors, one or more gas sensors, and a communication circuit or communication device configured to output sensor data to a system gateway. The system gateway is configured to receive and process the sensor data output from the threat sensing devices and determine whether the processed sensor data corresponds to one of a predetermined plurality of known threats (e.g., a gunshot) and, if so, to communicate the existence of the threat, the processed sensor information, and/or predetermined messaging information to one or more recipient devices (e.g., first responders, dispatchers).

18. A method of detecting and reporting a threat comprising:
-
mounting at least one threat sensing device in at least a first location inside a building, the at least one threat sensing device comprising a plurality of sensors, the plurality of sensors comprising an acoustic sensor, a gas sensor, a pressure sensor, and a first communication device configured to output sensor data along a communication pathway; outputting the sensor data to a system gateway, the system gateway comprising a second communication device configured to receive the sensor data from the at least one threat sensing device along the communication pathway; determining, using either the system gateway or the threat sensing device, whether the sensor data corresponds to a gunshot by processing a probability to give a confidence score based upon a sequence of the sensor data from the acoustic sensor, the pressure sensor, and the gas sensor wherein; when the confidence score is low, do nothing; when the confidence score is medium, record data in a memory; when the confidence score is high, automatically communicate the at least one of the existence of the threat, the sensor data, or one or more predetermined messages to the plurality of pre-registered recipient devices. - View Dependent Claims (19, 21)
