Portable Image Viewing Device for Aviation Security Screening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image screening systems for aviation security require multiple immobile viewing stations, increasing costs and limiting the correlation between physical luggage and X-ray or MMW images, which hampers detection efficiency and safety.
Innovation Solution
A portable image viewing device system that transmits and matches scanned images from X-ray, MMW, or other imaging technologies with the physical object, allowing for targeted inspections and improved detection capabilities by enabling image display on portable devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple immobile viewing stations are used to display X-ray and MMW images, then detection capability is improved, but system cost increases
Solution Approach 1:
The patent transforms static viewing stations into dynamic portable devices that can move freely throughout the screening environment. Inspectors carry portable image viewers to different locations, allowing the viewing function to be mobile rather than fixed, thereby reducing the need for multiple immobile stations while maintaining detection capability
Solution Approach 2:
The system creates digital copies of X-ray and MMW images that can be displayed on multiple portable devices simultaneously. Instead of requiring multiple physical viewing stations, the same image data is replicated and transmitted to various portable viewers, reducing hardware costs while maintaining detection coverage
2Area of stationary object
If multiple immobile viewing stations are deployed, then image viewing coverage is improved, but correlation between physical luggage and scanned image is lost
Solution Approach 1:
The portable image viewing device serves as an intermediary between the physical luggage and the scanned image. The device maintains the correlation by being physically present with the inspector examining the luggage, allowing real-time comparison of the physical item with its digital image representation while providing wide viewing coverage through portability
3Reliability
If more viewing stations and image scanners are added, then detection capability is improved, but the cost of screening systems increases
Solution Approach 1:
The portable image viewing device performs multiple functions: it displays X-ray images, displays MMW images, provides location flexibility, and maintains image-luggage correlation. This multi-functional device replaces the need for separate viewing stations and additional scanners, improving detection capability while reducing overall system cost

AI summary
An image screening apparatus includes an image scanner that scans an object and generates an image of the object; at least one portable image viewing device; and a controller including circuitry configured to transmit the generated image to the at least one portable image viewing device, trigger display of the transmitted image on a screen of at least one of the portable image viewing devices, and match the displayed image with the scanned object. An area of interest of the scanned object can be displayed on one portable image viewing device by hovering the one portable image viewing device over the area of interest.
