Abstract

In an exemplary embodiment, a gun-mounted recording device comprises a housing configured to be mounted to a gun, a recording module arranged within the housing, the recording module comprising a first electrical contact, and a power supply configured to be detachably coupled to the housing. The power source comprises a second electrical contact. The first electrical contact and the second electrical contact are configured to contact each other and form a circuit when the power source is coupled to the housing in order for the power source to supply power to the recording module. The first electrical contact, the second electrical contact, or both are configured to move in response to relative movement between the power source and the housing when the power source is coupled to the housing, in order to maintain the supply of power from the power source to the recording module.

Claims (38)

1. A gun-mounted electronic accessory device, the electronic accessory device comprising:

a housing configured to be mounted to a gun;

a power source configured to be received by and detachably coupled to the housing, the power source having a memory;

a recording module arranged within the housing, configured to record at least one aspect of the gun's environment to the memory of the power source, and communicatively coupled to a processing device arranged within the housing; and

a first illuminating device arranged within the housing and configured to illuminate an area forward of the gun-mounted electronic accessory device,

wherein the recording module comprises an internal power unit configured to power a clock.

2. The gun-mounted electronic accessory device of claim 1 , wherein the first illuminating device comprises one of a light-emitting diode and a laser module.

3. The gun-mounted electronic accessory device of claim 1 , wherein the first illuminating device comprises a light-emitting diode.

4. The gun-mounted electronic accessory device of claim 1 , wherein the first illuminating device comprises a laser module.

5. The gun-mounted electronic accessory device of claim 1 , the electronic accessory device being configured to allow functional control of the first illuminating device independent of functional control of the recording module.

6. The gun-mounted electronic accessory device of claim 1 , further comprising a user interface configured to functionally control the first illuminating device independent of functional control of the recording module.

7. The gun-mounted electronic accessory device of claim 1 , further comprising a second illuminating device arranged within the housing and configured to illuminate an area forward of the gun-mounted electronic accessory device.

8. The gun-mounted electronic accessory device of claim 7 , the first illuminating device comprising a light-emitting diode and the second illuminating device comprising a laser module.

9. The gun-mounted electronic accessory device of claim 8 , the first illuminating device being communicatively coupled to the processing device, wherein the first illuminating device is configured to activate when the recording module is activated.

10. The gun-mounted electronic accessory device of claim 1 , the first illuminating device being communicatively coupled to the processing device, wherein the first illuminating device is configured to activate when the recording module is activated.

11. The gun-mounted electronic accessory device of claim 1 , the housing having an outward facing surface comprising an exterior surface portion and an inner surface portion, the electronic accessory device further comprising:

a sensor communicatively coupled to the processing device, the sensor configured to:

sense the gun is in use; and

generate a first signal in response to sensing the gun is in use

wherein the power source having an outward facing surface comprising an exterior surface portion and an inner surface portion, wherein, when the power source is coupled to the housing, the inner surface portion of the power source interfaces with the inner surface portion of the housing and the exterior surface of the electronic accessory device comprises the exterior surface portions of the power source and the housing, and wherein, when the power source is detached from the housing for recharging, the housing containing the processing device and the recording module remains mounted to the gun,

the processing device being configured to:

detect the generated first signal; and

send a second signal in response to detecting the generated first signal; and

the recording module being configured to transition to a higher-power state in response to receiving the second signal and record at least one aspect of the gun's environment in response to the second signal.

12. The gun-mounted electronic accessory device of claim 11 , the housing having an upper mounting portion configured to be mounted under a barrel of the gun and the power source being downwardly disposed from the housing and positioned between forward and rearward ends of the housing.

13. The gun-mounted electronic accessory device of claim 1 , further comprising a second illuminating device arranged within the housing and configured to illuminate an area forward of the recording device.

14. The gun-mounted electronic accessory device of claim 13 , the first illuminating device comprising a light-emitting diode and the second illuminating device comprising a laser module.

15. A gun-mounted electronic accessory device having an exterior surface, the electronic accessory device comprising:

a housing configured to be mounted to a gun, the housing having an outward facing surface comprising an exterior surface portion and an inner surface portion;

at least one electronic device arranged within the housing and having an activation mechanism configured to transition the at least one electronic device from an inactive state to and active state; and

a power source configured to be received by and detachably coupled to the housing when the housing is mounted to the gun, the power source having an outward facing surface comprising an exterior surface portion and an inner surface portion, wherein, when the power source is coupled to the housing, the inner surface portion of the power source interfaces with the inner surface portion of the housing and the exterior surface of the electronic accessory device comprises the exterior surface portions of the power source and the housing, and wherein, when the power source is detached from the housing for recharging, the housing containing a processing unit and a recording module remains mounted to the gun, wherein the power source having a memory configured to store at least one aspect of an environment recorded by the recording module.

16. The gun-mounted electronic accessory device of claim 15 , the at least one electronic device comprising one or more of a recording module, a light-emitting diode, and a laser module.

17. The gun-mounted electronic accessory device of claim 15 , the at least one electronic device comprising

a recording module arranged within the housing, configured to record at least one aspect of the gun's environment and communicatively coupled to a processing device arranged within the housing; and

a first illuminating device arranged within the housing and configured to illuminate an area forward of the recording device.

18. The gun-mounted electronic accessory device of claim 17 , wherein the first illuminating device comprises a light-emitting diode or a laser module.

19. The gun-mounted electronic accessory device of claim 17 , wherein the first illuminating device comprises a light-emitting diode.

20. The gun-mounted electronic accessory device of claim 17 , the electronic accessory device being configured to allow functional control of the first illuminating device independent of functional control of the recording module.
