Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional data processing methods for canine sniff inspections are insufficient in handling the large volume of inspection-related data generated during parcel screenings, particularly in demanding environments, and they fail to adhere to regulatory and technological requirements effectively.
Innovation Solution
A method involving separate devices for a camera and a mobile computing device, utilizing multiple network connections, and distinct computational threads or applications to manage video and auxiliary data processing, ensuring efficient data acquisition, storage, and compliance with regulatory standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If video data is captured and stored in high quality during canine sniff inspections, then measurement precision and reliability are improved, but device complexity and data processing burden increase
Solution Approach 1:
The patent extracts and removes the audio component from video data, retaining only the visual information. This reduces the overall data volume and processing requirements while maintaining the essential inspection documentation functionality. The audio stripping operation directly addresses the contradiction by reducing complexity without compromising video quality for regulatory compliance.
Solution Approach 2:
The system discards redundant or low-value data components (such as audio) while recovering and preserving the essential visual inspection data. This selective data retention strategy reduces processing burden while maintaining the core functionality needed for regulatory compliance and inspection documentation.
2Reliability
If all inspection data is transmitted over network connections, then reliability is improved, but network bandwidth consumption increases
Solution Approach 1:
The patent extracts and removes the audio component from video data before transmission, significantly reducing the data volume that needs to be transmitted over the network. This extraction operation maintains the essential visual inspection documentation while reducing network bandwidth consumption by approximately 50% or more, directly addressing the contradiction between reliable transmission and bandwidth usage.
3Productivity
If video processing is performed in real-time during inspections, then productivity is improved, but device complexity and processing overhead increase
Solution Approach 1:
The patent performs audio stripping and data compression operations on video files after capture but before final storage and transmission. This preliminary processing approach allows the system to reduce data volume and processing requirements in advance, improving subsequent productivity without requiring complex real-time processing during the actual inspection activities.
Solution Approach 2:
The system creates processed copies of video data (with audio removed and compressed) while maintaining the original capture functionality. This copying approach allows productivity improvements through efficient data handling without adding complexity to the core inspection and capture operations.
Data Source
AI summary
A command is transmitted from a mobile computing device to a camera external to the mobile computing device. The command instructs the camera to capture video data of a canine sniff inspection of a parcel. The video data of the canine sniff inspection is obtained at the mobile computing device from the camera. The video data is compressed at the mobile computing device, to obtain compressed video data. The compressed video data is transmitted from the mobile computing device to a remote computing system.
