Solution Overview
Problem
Conventional night vision devices are unable to record images and/or overlay data that can be helpful to the user, limiting their situational awareness.
Innovation Solution
A multi-task augmented reality heads up display (MTAR-HUD) that connects between a night vision device and an eyepiece, featuring a camera, decoder, and display to transform analog images into digital information, allowing for image recording and data overlay.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional night vision devices are used, then images can be viewed in low light conditions, but images cannot be recorded and data cannot be overlayed
Solution Approach 1:
The patent applies multi-functionality by integrating multiple capabilities into a single device: the night vision device is enhanced with camera functionality for image recording, decoder for signal conversion, and display for data overlay. This allows the device to perform viewing, recording, and data presentation functions simultaneously, resolving the contradiction between versatility and complexity.
Solution Approach 2:
The patent merges conventional night vision components with digital imaging and display technologies. The housing integrates the night vision device, camera, decoder, and display into a unified structure, combining analog night vision capability with digital recording and display functions to achieve both versatility and manageable complexity.
2Loss of information
If conventional night vision devices are used, then simple viewing is possible, but situational awareness is limited due to lack of data overlay
Solution Approach 1:
The decoder acts as an intermediary between the night vision device and the display, converting analog signals to digital signals that can be processed and overlayed with data. This intermediary component enables enhanced situational awareness by facilitating the integration of multiple information sources without directly complicating the core night vision function.
Solution Approach 2:
The patent adds a dimensional layer of information overlay on top of the conventional night vision image. By introducing data display in a separate dimension (digital overlay layer) rather than modifying the fundamental optical path, the system enhances situational awareness while maintaining the simplicity of the core viewing function.
3Adaptability or versatility
If image conversion from analog to digital is implemented, then recording and data overlay become possible, but device complexity increases
Solution Approach 1:
The patent extracts the signal conversion function into a separate, dedicated decoder component. By isolating the analog-to-digital conversion process in a distinct module, the system achieves data overlay capability while keeping the overall device architecture manageable, as the decoder can be independently designed and integrated without complicating the entire system.

Function Achieved in This Case
The MTAR-HUD enhances situational awareness by enabling the recording of images and overlaying crucial information onto the image, providing increased functionality beyond conventional night vision devices.
Implementation Method 1
a camera configured to receive an image from the night vision device, a decoder configured to convert the image from the camera from an analogue signal into digital signal
Data Source
AI summary
A display device includes a housing having a first end capable of connecting to a night vision device and a second end capable of connecting to an eyepiece, a camera configured to receive an image from the night vision device, a decoder configured to convert the image from the night vision device from an analogue signal into digital signal, and a display to display the converted image, so that the converted image can be viewed though the eyepiece.
