Abstract

A digital sight for a weapon includes a sight body, a mount for a peripheral fixed to the sight body, and a controller. The controller is disposed in communication with a non-volatile memory and is responsive to instructions recorded to boresight a peripheral relative to the digital weapon sight. Weapon assemblies and methods of boresighting peripherals to digital weapon sights are also described.

First claim

What is claimed is:

1. A digital sight for a weapon, comprising:
a sight body;
a mount for a peripheral fixed to the sight body; and
a controller disposed in communication with a non-volatile memory, wherein the controller is responsive to instructions recorded on the memory to boresight a peripheral relative to the digital sight using a mount offset associated with the mount and recorded on the non-volatile memory.

2. The digital sight as recited in claim 1 , further comprising a display fixed relative to the mount, the controller operatively connected to the display.

3. The digital sight as recited in claim 1 , further comprising a data connector, the controller in communication with the data connector to receive sensor data from the peripheral.

4. The digital sight as recited in claim 1 , wherein the non-volatile memory has recorded on it a mount offset for boresighting the mount to an image sensor.

5. The digital sight as recited in claim 4 , wherein the mount offset is a differential between pointing of the mount and the image sensor relative to a reference digital sight.

6. The digital sight as recited in claim 1 , further comprising a peripheral removably fixed to the mount.

7. The digital sight as recited in claim 6 , wherein the peripheral includes a sensor disposed in communication with the controller, the sensor having a field of view overlapping a field of view of an image sensor, the sensor having pointing offset relative to image sensor pointing.

8. The digital sight as recited in claim 6 , wherein the peripheral includes a non-volatile memory having a peripheral offset recorded on it for boresighting the peripheral relative to a digital sight, the non-volatile memory disposed in communication with the controller.

9. The digital sight as recited in claim 8 , wherein the peripheral offset is a differential between pointing of a sensor relative to pointing of a reference sensor.

10. The digital sight as recited in claim 6 , wherein the instructions cause the controller to:
receive the mount offset from the digital sight memory;
receive a peripheral offset from the peripheral;
boresight the peripheral to the digital sight by adding the mount offset to the peripheral offset; and
shift data received from a peripheral sensor relative to image data received from an image sensor by the boresight for display on a display of the digital sight.

11. The digital sight as recited in claim 6 , wherein the peripheral comprises:
a peripheral controller operatively connected to a sensor; and
a data connector in communication with the digital sight controller and the peripheral controller.

12. The digital sight as recited in claim 6 , wherein the peripheral includes a digital camera or a laser range finder.

13. A weapon assembly, comprising:
a weapon with a digital weapon sight as recited in claim 1 fixed to the weapon; and
a peripheral with a sensor removably fixed to the digital sight mount and boresighted to the sensor of the digital sight,
wherein the sensor is boresighted to the image sensor without mechanically adjusting the peripheral once removably fixed to the mount.

14. A method of boresighting a peripheral to a digital sight, comprising:
at a digital weapon sight including a sight body, a mount fixed relative to the sight body, and a controller disposed in communication with a non-volatile memory,
removably fixing a peripheral to the mount; and
boresighting the peripheral relative to the sight body upon removable fixation of the peripheral to the mount, wherein boresighting includes receiving a mount offset stored in the digital weapon sight non-volatile memory.

15. The method as recited in claim 14 , further comprising:
measuring a difference between pointing of the mount and pointing of the mount on a reference digital weapon sight; and
storing the difference between pointing of the mount and pointing of the mount on the reference digital weapon sight as a mount offset in the non-volatile memory of the digital weapon sight.

16. The method as recited in claim 14 , wherein boresighting the peripheral includes receiving a peripheral offset from the peripheral.

17. The method as recited in claim 16 , further comprising:
measuring a difference between pointing of the peripheral and pointing of reference peripheral; and
storing the difference between pointing of the peripheral and pointing of reference peripheral as a peripheral in a memory of the peripheral.

18. The method as recited in claim 14 , further comprising:
receiving a mount offset from the digital weapon sight memory;
receiving a peripheral offset from the peripheral, wherein boresighting the peripheral to the digital weapon sight includes determining a boresight adjustment of the peripheral by adding the mount offset to the peripheral offset; and
shifting data received from the peripheral relative to image data received from the digital weapon sight by the boresight adjustment.

19. The method as recited in claim 18 , further comprising displaying the shifted data and image data on a display.
