Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for verifying data accuracy in visual images, such as those used in aircraft flight decks, do not effectively ensure that the data displayed matches the intended data, leading to potential errors that can result in safety issues.
Innovation Solution
A system comprising a data processing component, render component, and data verification component that analyzes and interprets sensor data to generate and verify the accuracy of visual images displayed, using a splitter to route light energy for both display and verification, allowing for real-time correction of errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If data verification is performed by comparing displayed data to processed data, then data accuracy is improved, but system complexity increases due to additional verification components
Solution Approach 1:
The patent combines the verification function with the existing display system by using the same display device to present both the visual image and the verification indicator. The data verification component is integrated into the existing data processing pipeline, comparing processed data against source sensor data without requiring completely separate verification hardware. This merging approach reduces overall system complexity while maintaining verification capability.
Solution Approach 2:
The patent introduces a verification indicator as an intermediary element that mediates between the complex verification process and the user. Instead of displaying raw verification data or requiring complex interpretation, the system uses simplified visual indicators (such as checkmarks or color codes) to communicate verification status. This intermediary layer maintains data accuracy verification while simplifying the user interface and reducing perceived system complexity.
2Ease of operation
If visual images are used to present data, then information presentation is improved, but data accuracy cannot be ensured leading to safety issues
Solution Approach 1:
The patent implements a feedback mechanism where the system continuously verifies displayed data against source sensor data and provides real-time verification status to the user. The data verification component monitors the integrity of data throughout the processing pipeline and feeds verification results back to the display, allowing users to confirm data accuracy while maintaining ease of information presentation. This closed-loop feedback ensures reliability without compromising usability.
Solution Approach 2:
The patent performs data verification in advance of final data presentation by comparing processed data against source sensor data before the data is fully rendered for display. The verification indicator is prepared and integrated into the visual image beforehand, ensuring that only verified data is presented to the user. This preliminary verification action prevents inaccurate data from being displayed, thereby ensuring reliability while maintaining ease of operation.

AI summary
Data presented in a visual image is monitored and verified. A processing component 104 receives data from sensors and other sources, and interprets the data to generate processed data. A render component 106 generates a visual image based on the processed data. A projector component 108 projects the image, which is received by a splitter component 112 that splits the light stream of the image and routes a portion of light energy to the display screen viewed by the user and another portion of the light energy to a data verification component (DVC) 114. DVC 114 interprets information presented in the image to determine the data being presented to the user by the image. DVC 114 also receives the processed data from the processing component 104. DVC 114 compares the data determined from the image to the processed data to determine whether they match and takes appropriate responsive action if they do not match.
