Rifle Scope Display Adapter for Hands-Free Targeting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sniper rifle targeting systems require manual adjustments and verbal communication, which can compromise accuracy and safety by requiring the sniper to remove their hands and eyes from the target, and generate noise that may reveal their position.
Innovation Solution
A rifle scope display adapter that projects aiming and trajectory information as illuminated symbology onto the target view, allowing the sniper to align a targeting reticle without manual adjustments or looking away, using a ballistic computer and LCOS technology for precise windage and elevation calculations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual scope adjustments are made based on verbal communication, then targeting accuracy can be achieved, but the sniper must remove hands and eyes from the target position, compromising stability and situational awareness
Solution Approach 1:
The patent replaces manual mechanical scope adjustments with an automated electronic display system that shows reticle adjustments directly in the scope's field of view. The system uses a ballistic computer to calculate windage and elevation corrections, then displays these as visual reticle offsets on an LCD screen within the scope, eliminating the need for manual knob adjustments and maintaining hands-on-rifle stability.
Solution Approach 2:
The patent introduces an intermediary electronic display system between the ballistic computer and the sniper's view. The display adapter receives data from the ballistic computer and presents it as visual reticle offsets on an LCD screen that overlays the scope's natural field of view, allowing the sniper to see adjustment information without removing eyes from the target.
2Loss of information
If verbal communication is used to transmit targeting information, then coordination between spotter and sniper is achieved, but noise is generated that may reveal their position
Solution Approach 1:
The patent replaces verbal acoustic communication with electronic digital communication. The ballistic computer receives target data and calculates adjustments electronically, then transmits this information through the display adapter to the sniper's scope. This eliminates the need for voice communication between spotter and sniper, removing the acoustic signature that could reveal their position.
3Measurement precision
If manual scope adjustments are made, then firing solution can be applied, but time is lost and the sniper must take eyes off the target
Solution Approach 1:
The patent performs preliminary computational actions through the ballistic computer, which calculates windage and elevation corrections in advance based on environmental sensors and target data. The results are immediately displayed as reticle offsets on the scope's LCD screen, allowing the sniper to apply the firing solution without manual adjustment time and without removing eyes from the target.
Solution Approach 2:
The patent substitutes manual mechanical adjustment with electronic display of pre-calculated reticle offsets. The ballistic computer performs all calculations electronically and the display adapter presents the final reticle position directly on the scope's screen, eliminating the time-consuming process of manual scope adjustments.
4Measurement precision
If the sniper removes hands from the firing position to adjust the scope, then scope positioning can be corrected, but rifle stability shifts on the support
Solution Approach 1:
The patent replaces manual mechanical scope repositioning with electronic display of adjusted reticle offsets. The ballistic computer calculates the necessary corrections and the display adapter shows the modified reticle position on the LCD screen within the scope's field of view. This allows the scope to remain physically stable on the rifle while the reticle position is adjusted electronically.

AI summary
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.
