Abstract

A method, apparatus and system for networking accessories to a firearm or weapon wherein the accessories are conductively powered from the rail and data is transferred between the accessories and the rail via conductive coupling. In one embodiment, a weapon is provided, the weapon having: an upper receiver; a lower receiver; a powered accessory mounted to a rail of the upper receiver; and an apparatus for conductively networking a microcontroller of the powered accessory to a microcontroller of the upper receiver and a microcontroller of the lower receiver, wherein the data is exclusively provided to the powered accessory from the rail.

Claims

1. A rail for a weapon, the rail comprising:

a plurality of slots and a plurality of ribs each being located in an alternating fashion on a surface of the rail;

a first plurality of pins each having an end portion located on a surface of one of a first plurality of the plurality of ribs;

a second plurality of pins each having a first end portion and a second end portion located on a surface of a second plurality of the plurality of ribs; and

a plurality of pins located in the rail for power and data transfer, wherein the plurality of pins located in the rail have an exposed contact surface comprising tungsten carbide.

2. The rail as in claim 1, wherein each of the second plurality of the plurality of ribs is adjacent to at least two of the first plurality of ribs.

3. The rail as in claim 1, wherein an intermediate portion of each of the second plurality of pins is located adjacent to a switch located in the rail, wherein the switch is either opened or closed when the intermediate portion is magnetized.

4. In combination, a powered accessory and a rail configured to removably receive and retain the powered accessory;

an apparatus for conductively providing power and data to the powered accessory, wherein the data is exclusively provided to the powered accessory from a power source in the rail; and

wherein the rail comprises;

a plurality of slots and a plurality of ribs each being located in an alternating fashion on a surface of the rail;

a first plurality of pins each having an end portion located on a surface of one of a first plurality of the plurality of ribs;

a second plurality of pins each having a first end portion and a second end portion located on a surface of a second plurality of the plurality of ribs; and

a plurality of pins located in the rail for power and data transfer, wherein the plurality of pins located in the rail have an exposed contact surface comprising tungsten carbide.

5. A weapon, comprising:

an upper receiver;

a lower receiver;

a powered accessory mounted to a rail of the upper receiver; and

an apparatus for conductively providing power and data to the powered accessory; and

wherein the rail comprises;

a plurality of slots and a plurality of ribs each being located in an alternating fashion on a surface of the rail;

a first plurality of pins each having an end portion located on a surface of one of a first plurality of the plurality of ribs;

a second plurality of pins each having a first end portion and a second end portion located on a surface of a second plurality of the plurality of ribs; and

a plurality of pins located in the rail for power and data transfer, wherein the plurality of pins located in the rail have an exposed contact surface comprising tungsten carbide.

6. A method of networking a removable accessory of a weapon to a microcontroller of the weapon, comprising:

conductively transferring data between the accessory and the microcontroller via at least one pin having an exposed contact surface comprising tungsten carbide;

conductively transferring power to the accessory via at least one pin having an exposed contact surface comprising tungsten carbide; and

wherein the microcontroller is capable of determining whether to transfer data or power via magnetization of at least one pin located on the weapon.

9. The method as in claim 6, wherein the accessory is removably secured to a rail of the weapon, the rail comprising:

a plurality of slots and a plurality of ribs each being located in an alternating fashion on a surface of the rail;

a first plurality of pins each having an end portion located on a surface of one of a first plurality of the plurality of ribs; and

a second plurality of pins each having a first end portion and a second end portion located on a surface of a second plurality of the plurality of ribs; and

wherein the at least one of the first plurality of pins or the second plurality of pins is used to determine whether the removably accessory has been secured to the weapon.

10. The method as in claim 6, wherein the accessory is removably secured to a rail of the weapon, the rail comprising:

a plurality of slots and a plurality of ribs each being located in an alternating fashion on a surface of the rail;

a first plurality of pins each having an end portion located on a surface of one of a first plurality of the plurality of ribs; and

a second plurality of pins each having a first end portion and a second end portion located on a surface of a second plurality of the plurality of ribs; and

wherein the at least one of the first plurality of pins or the second plurality of pins is used to determine whether the removably accessory has been secured to the weapon.

7. A method of networking a removable accessory of a weapon to a microcontroller of the weapon, comprising:

conductively or inductively transferring data between the accessory and the microcontroller via at least one pin having an exposed contact surface comprising tungsten carbide;

conductively or inductively transferring power to the accessory via at least one pin having an exposed contact surface comprising tungsten carbide; and

wherein the microcontroller is capable of determining whether to transfer data or power via magnetization of at least one pin located on the weapon.

8. The method as in claim 7, wherein the accessory is secured to a rail of the weapon, the rail comprising:

a plurality of slots and a plurality of ribs each being located in an alternating fashion on a surface of the rail;

a first plurality of pins each having an end portion located on a surface of one of a first plurality of the plurality of ribs;

a second plurality of pins each having a first end portion and a second end portion located on a surface of a second plurality of the plurality of ribs; and

a plurality of pins located in the rail for power and data transfer, wherein the plurality of pins located in the rail have an exposed contact surface comprising tungsten carbide.
