Abstract

A firearm used in military applications may have a plurality of accessories that can be attached to the weapon, with each accessory having a need for electric power. In order to reduce the weight of these power-consuming accessories, as well as the proliferation of batteries used to power these power-consuming accessories, a Powered Rail provides a point of mechanical and electrical interconnection for the power-consuming accessories with a common power source. The Weapon Accessory Control System is provided to enable the user to control the activation of a power-consuming accessory as well as enable communications between the user and the power-consuming accessory and among power-consuming accessories.

Claims

1. A weapon accessory control system for use with a Powered Rail that extends along at least a portion of a length of a barrel of a weapon for providing a source of electrical power to at least one power-consuming accessory that is mechanically and electrically attached to the Powered Rail, the weapon accessory control system comprising:

an accessory control apparatus for enabling a user to select command and control functions for each power-consuming accessory connected to the Powered Rail; and

a powered control module, electrically connected to the Powered Rail and responsive to the user selecting a command and control function for a particular power-consuming accessory, for transmitting control signals indicative of the user selecting a command and control function for a particular power-consuming accessory to the particular power-consuming accessory via the Powered Rail to control the operation of the particular power-consuming accessory.

2. The weapon accessory control system of claim 1 wherein said powered control module comprises:

a microcontroller which is maintained in an off state in the absence of an interrupt, user button push, or timer expiration.

3. The weapon accessory control system of claim 1, further comprising:

wherein said accessory control apparatus comprises;

a plurality of buttons, located in a Powered Rail and operable by a user of the weapon, each of which corresponds to a predetermined operation of a selected power-consuming accessory; and

wherein said powered control module comprises;

a button rules table which stores data indicative of a predetermined operation to be performed by the power-consuming accessory in response to data received from the Powered Rail indicative of a button push operation performed by the user.

4. The weapon accessory control system of claim 3 wherein said powered control module further comprises:

a device type table which stores data indicative of characteristics of power-consuming accessories that can be connected to the Powered Rail.

5. The weapon accessory control system of claim 1 wherein said powered control module comprises:

a connection table which stores data indicative of the power-consuming accessories connected to the Powered Rail with which the weapon accessory control system is communicatively coupled via the Powered Rail.

6. The weapon accessory control system of claim 1 wherein the powered control module, when located in a power-consuming accessory, comprises:

a power regulator, which is responsive to the control signals received from the weapon accessory control system via the Powered Rail, for regulating the flow of power from the Powered Rail to a device in the power-consuming accessory which draws power from the Powered Rail.

7. The weapon accessory control system of claim 6 wherein the power regulator comprises:

a Pulse Width Modulation controller for regulating the flow of power from the Powered Rail to a device in the power-consuming accessory which draws power from the Powered Rail.

8. The weapon accessory control system of claim 1 wherein said powered control module comprises:

a signal generator for generating a plurality of signals, each unique to a predetermined power-consuming accessory.

9. The weapon accessory control system of claim 8 wherein said accessory control apparatus is connected to said signal generator for enabling a user to control the generation of said plurality of signals by said signal generator.

10. The weapon accessory control system of claim 9 wherein said powered control module further comprises:

a transceiver operatively connected to said signal generator for coupling each of said plurality of signals to said at least one Powered Rail.

11. A method of operating a weapon accessory control system for use with a Powered Rail that extends along at least a portion of a length of a barrel of a weapon for providing a source of electrical power to at least one power-consuming accessory that is mechanically and electrically attached to the Powered Rail, the weapon accessory control system comprising:

enabling a user to select command and control functions for each power-consuming accessory connected to the Powered Rail on an accessory control apparatus connected to the Powered Rail; and

transmitting control signals from a powered control module, electrically connected to the Powered Rail and responsive to the user selecting a command and control function for a particular power-consuming accessory, indicative of the user selecting a command and control function for a particular power-consuming accessory to the particular power-consuming accessory via the Powered Rail to control the operation of the particular power-consuming accessory.

12. The method of operating a weapon accessory control system of claim 11 wherein said step of transmitting control signals comprises:

maintaining a microcontroller, located in the powered control module, in an off state in the absence of an interrupt, user button push, or timer expiration.

13. The method of operating a weapon accessory control system of claim 11, further comprising:

wherein said step of enabling a user comprises;

presenting a plurality of buttons, located in the accessory control apparatus and operable by a user of the weapon, each of which corresponds to a predetermined operation of a selected power-consuming accessory; and

wherein said step of transmitting control signals comprises;

storing data, in a button rules table, indicative of a predetermined operation to be performed by the power-consuming accessory in response to data received from the Powered Rail indicative of a button push operation performed by the user.

14. The method of operating a weapon accessory control system of claim 13 wherein said step of transmitting control signals further comprises:

providing a device type table which stores data indicative of characteristics of power-consuming accessories that can be connected to the Powered Rail.

15. The method of operating a weapon accessory control system of claim 11 wherein said step of transmitting control signals comprises:

providing a connection table which stores data indicative of the power-consuming accessories connected to the Powered Rail with which the weapon accessory control system is communicatively coupled via the Powered Rail.

16. The method of operating a weapon accessory control system of claim 11 wherein the step of transmitting control signals, when executed in a power-consuming accessory, comprises:

regulating, in response to the control signals received from the weapon accessory control system via the Powered Rail, the flow of power from the Powered Rail to a device in the power-consuming accessory which draws power from the Powered Rail.

17. The method of operating a weapon accessory control system of claim 16 wherein the step of regulating comprises:

operating a Pulse Width Modulation controller for regulating the flow of power from the Powered Rail to a device in the power-consuming accessory which draws power from the Powered Rail.

18. The method of operating a weapon accessory control system of claim 11 wherein said step of transmitting control signals comprises:

generating a plurality of signals, each unique to a predetermined power-consuming accessory, in a signal generator.

19. The method of operating a weapon accessory control system of claim 18 wherein said accessory control apparatus is connected to said signal generator for enabling a user to control the generation of said plurality of signals by said signal generator.

20. The method of operating a weapon accessory control system of claim 19 wherein said step of transmitting control signals further comprises:

coupling each of said plurality of signals to said at least one Powered Rail.
