US12736307 - Enhanced precision disturbed zero sighting system for long-range target engagement

A weapon sighting system and method are provided for engaging distant targets with precision. The system includes an in-line or clip-on weapon sight integrated with a fire control system (FCS) that generates ballistic messages for Elevation (ELEV) HOLD and Windage (WIND) HOLD. A sensor capable of detecting various infrared wavelengths is included, allowing for periscopic or prism transforms based on the ballistic solution for a target. This disclosed system enables shooters to engage targets with high accuracy and precision at extreme ranges without losing sight of the firing solution when increasing magnification.

The patent describes an advanced optical sighting system for firearms that integrates a fire control system to provide precise ballistic data for elevation and wind adjustments, allowing shooters to engage distant targets without manual reticle adjustments. This system employs a chipset to execute periscopic or prism transformations based on the ballistic data, ensuring high accuracy at extreme ranges.

Claim 1

1 . A disturbed zero optical sighting system for firearms, comprising: an in-line/clip-on weapon sight capable of receiving ballistic data and disturbing an image output based on calculated elevation (ELEV) and wind (WIND) holds; a clear view optic configured to align an etched reticle with a target when viewed through the in-line/clip-on weapon sight; and a firearm-mounted integrated fire control system (FCS) configured to send the ballistic data to the in-line/clip-on weapon sight; wherein the in-line/clip-on weapon sight disturbs the image output such that the target can be engaged at a zero position of the etched reticle of the clear view optic without requiring any adjustment for the ELEV and WIND holds; and wherein the in-line/clip-on weapon sight comprises a chipset configured to execute elevation and windage periscopic/prism transformations within the sighting system based on the ballistic data, wherein the periscopic/prism transformations comprise: [x,y]→[X=x±ELEV mils/{focal length/Pixel Pitch}, Y=y], wherein X is calculated for elevation without a wind correction; or [x,y]→[X=x±ELEV Mils/{focal length/Pixel Pitch}, Y=y±WIND mils/{focal length/pixel pitch}], wherein X is transformed for elevation and Y is transformed for a wind correction. an in-line/clip-on weapon sight capable of receiving ballistic data and disturbing an image output based on calculated elevation (ELEV) and wind (WIND) holds; a clear view optic configured to align an etched reticle with a target when viewed through the in-line/clip-on weapon sight; and a firearm-mounted integrated fire control system (FCS) configured to send the ballistic data to the in-line/clip-on weapon sight; wherein the in-line/clip-on weapon sight disturbs the image output such that the target can be engaged at a zero position of the etched reticle of the clear view optic without requiring any adjustment for the ELEV and WIND holds; and wherein the in-line/clip-on weapon sight comprises a chipset configured to execute elevation and windage periscopic/prism transformations within the sighting system based on the ballistic data, wherein the periscopic/prism transformations comprise: [x,y]→[X=x±ELEV mils/{focal length/Pixel Pitch}, Y=y], wherein X is calculated for elevation without a wind correction; or [x,y]→[X=x±ELEV Mils/{focal length/Pixel Pitch}, Y=y±WIND mils/{focal length/pixel pitch}], wherein X is transformed for elevation and Y is transformed for a wind correction.
