Abstract
A method and apparatus for detecting that a stun gun has been deployed is provided herein. During operation a periodic nature of a stun-gun voltage will be utilized to determine if the stun-gun has been fired. More specifically, an electric/magnetic field (EMF) and/or a sound will be analyzed to determine if the periodic nature of the EMF and/or sound matches that of a stun gun. If so, a command center will be notified of the event. In order to increase the accuracy of any stun-gun detect, a gun-draw sensor may be used in combination with the above technique.
Claims18
An apparatus comprising:
- a receiver configured to receive sensor states from a gun-drawn sensor and at least one additional sensor, the sensor states from the at least one additional sensor indicating whether an electric field or a magnetic field has been detected that matches a fingerprint of a stun gun being fired;
- and
- logic circuitry configured to map the sensor states to a stun-gun fired state when:
- (1) the gun-drawn sensor indicates that the stun gun has been removed from a holster, and
- (2) the at least one additional sensor indicates that the electric field or the magnetic field matches the fingerprint of the stun gun being fired.
(canceled)
An apparatus comprising:
- a personal-area network (PAN) transceiver configured to receive sensor states from a gun-drawn sensor and at least one additional sensor, the sensor states from the at least one additional sensor indicating whether an electric field or a magnetic field has been detected that matches a fingerprint of a stun gun being fired;
- logic circuitry configured to map the sensor states to a stun-gun fired state when:
- (1) the gun-drawn sensor indicates that the stun gun has been removed from a holster, and
- (2) the at least one additional sensor indicates that the electric field or the magnetic field matches the fingerprint of the stun gun being fired;
- and
- a wide-area network (WAN) transceiver configured to transmit the stun-gun fired state to a dispatch/command center.
(canceled)
A method comprising:
- receiving sensor states from a gun-drawn sensor and at least one additional sensor, the sensor states from the at least one additional sensor indicating whether an electric field or a magnetic field has been detected that matches a fingerprint of a stun gun being fired;
- mapping the sensor states to a stun-gun fired state when:
- (1) the gun-drawn sensor indicates that the stun gun has been removed from a holster, and
- (2) the at least one additional sensor indicates that the electric field or the magnetic field matches the fingerprint of the stun gun being fired;
- and
- transmitting the stun-gun fired state to a dispatch/command center.
