Abstract

This disclosure describes a compact and lightweight rifle scope display adapter configured to be affixed in front of the objective lens of a rifle scope. The display adapter includes a receptacle that enables the adapter to be electrically connected to a ballistic computer, rangefinder or other targeting mechanism. The display adapter is configured to receive aimpoint information and project illuminated symbology that is brought into focus by the rifle scope optics in such a way that the symbology appears to overlay an image of a scene on which the rifle scope is focused. The display adapter includes a casing that houses processing circuitry, a light emitting diode, polarizer, polarized beam splitter, liquid crystal on silicon imaging element and reflective element. The display adapter also includes a light bar, spherical mirror, quarter-wave plate and an additional polarized beam splitter contained within the light bar.

First claim

What is claimed is:

1 . A rifle display adapter that is configured to mount to a frame of a rifle scope, the rifle display adapter comprising:
a display device configured to project an image through an objective lens of the rifle scope; a one or more processors; and one or more memory devices comprising instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
sending position information of the rifle display adapter to a ballistic computer;
receiving a firing solution from the ballistic computer; and
displaying a targeting reticle on the display device, wherein the targeting reticle is displayed relative to a crosshair of the rifle scope according to the firing solution.

2 . The rifle display adapter of claim 1 , wherein the instructions cause the one or more processors to perform additional operations comprising:
displaying a crosshair on the display device that can be visually aligned with the crosshair of the rifle scope.

3 . The rifle display adapter of claim 2 , further comprising:
a control pad comprising controls that can rotate, horizontally shift, and vertically shift the crosshair on the display device.

4 . The rifle display adapter of claim 1 , wherein the instructions cause the one or more processors to perform additional operations comprising:
displaying a calculated windage measurement.

5 . The rifle display adapter of claim 1 , wherein the instructions cause the one or more processors to perform additional operations comprising:
displaying a calculated range to a target.

6 . The rifle display adapter of claim 1 , wherein the instructions cause the one or more processors to perform additional operations comprising:
displaying a graphic, wherein the position of the graphic visually indicates a convergence of a windage calculation algorithm.

7 . The rifle display adapter of claim 6 , wherein:
the graphic comprises one or more graphical elements that visually converge on a center point as the windage calculation algorithm converges.

8 . The rifle display adapter of claim 1 , wherein:
the rifle display adapter further comprises a gravitational tilt sensor; and the position information comprises a tilt of the rifle display adapter as measured by the gravitational tilt sensor.

9 . The rifle display adapter of claim 1 , wherein:
the firing solution received from the ballistic computer comprises a windage adjustment and an elevation adjustment.

10 . The rifle display adapter of claim 1 , wherein:
the targeting reticle is displayed such that the targeting reticle overlays an image visible through an eyepiece of the rifle scope.

11 . A method of displaying firing solutions using a display adapter that is configured to mount to a frame of a rifle scope, the method comprising:
sending position information of the rifle display adapter from the rifle display adapter to a ballistic computer; receiving, at the rifle display adapter, a firing solution from the ballistic computer; and displaying a targeting reticle on a display device of the rifle display adapter, wherein the targeting reticle is displayed relative to a crosshair of the rifle scope according to the firing solution.

12 . The method of claim 11 , further comprising:
displaying a crosshair on the display device that can be visually aligned with the crosshair of the rifle scope.

13 . The method of claim 12 , further comprising:
receiving inputs at a control pad of the rifle scope adapter that rotate, horizontally shift, and vertically shift the crosshair on the display device.

14 . The method of claim 11 , further comprising:
displaying a calculated windage measurement.

15 . The method of claim 11 , further comprising:
displaying a calculated range to a target.

16 . The method of claim 11 , further comprising:
displaying a graphic, wherein the position of the graphic visually indicates a convergence of a windage calculation algorithm.

17 . The method of claim 16 , wherein:
the graphic comprises one or more graphical elements that visually converge on a center point as the windage calculation algorithm converges.

18 . The method of claim 11 , wherein:
the rifle display adapter comprises a gravitational tilt sensor; and the position information comprises a tilt of the rifle display adapter as measured by the gravitational tilt sensor.

19 . The method of claim 11 , wherein:
the firing solution received from the ballistic computer comprises a windage adjustment and an elevation adjustment.

20 . The method of claim 11 , wherein:
the targeting reticle is displayed such that the targeting reticle overlays an image visible through an eyepiece of the rifle scope.
