Abstract
Subject matter disclosed herein relates to an apparatus, device, or method for detecting aim or pointing direction of a firearm, the method comprising detecting a sound signature of a gunshot from the firearm; sensing an aim direction of the firearm substantially at the time of detecting the sound signature of the gunshot; setting a reference direction based, at least in part, on the aim direction; sensing a current aim direction of the firearm; comparing the current aim direction to the reference direction; and initiating an alarm if the current aim direction is beyond a threshold angle of displacement from the reference direction.
Claims20
A method for detecting a shooter's aim or pointing direction of a firearm, the method comprising:
- using a sound detector to detect a sound signature of a gunshot from said firearm;
- using a 3D sensor to sense an aim direction of said firearm substantially at the time of detecting said sound signature of said gunshot;
- using electronics or a processor to set a reference direction based, at least in part, on said aim direction;
- sense a current aim direction of said firearm;
- compare said current aim direction to said reference direction;
- and
- initiate an alarm if said current aim direction is beyond a threshold angle of displacement from said reference direction.
A device for detecting a shooter's aim or pointing direction of a firearm, the device comprising:
- a sound detector to detect a sound of a gunshot from said firearm;
- a 3D sensor to sense an aim direction of said firearm;
- and
- a processor or electronics to:
- set a reference direction based, at least in part, said aim direction at a time when said sound of said gunshot is detected;
- compare a current aim direction to said reference direction;
- and
- initiate an alarm if said current aim direction is beyond a threshold angle of displacement from said reference direction.
A non-transitory storage medium comprising machine-readable instructions stored thereon that are executable by a special purpose computing device to:
- identify a sound signature of a gunshot from said firearm;
- determine an aim direction of said firearm substantially at the time of identifying said sound signature of said gunshot;
- set a reference direction based, at least in part, on said aim direction;
- determine a current aim direction of said firearm;
- compare said current aim direction to said reference direction;
- and
- initiate an alarm if said current aim direction is beyond a threshold angle of displacement from said reference direction.
