Portable Capture Device Automatic Emergency Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable information capturing devices often fail to timely capture critical media data during emergencies due to manual activation requirements, leading to missed opportunities for real-time evidence recording.
Innovation Solution
An environmental surveillance system comprising status sensors, a control device, and portable information capturing devices that automatically initiate media capture upon sensing specific emergency conditions, using broadcast packets with actuation commands to activate the devices instantly and automatically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the portable information capturing device is kept in manual activation mode, then the device can be activated only when needed, but the device fails to capture critical media data during emergencies due to delayed manual activation
Solution Approach 1:
The system performs preliminary actions by continuously monitoring environmental parameters through status sensors before an emergency occurs. When predefined emergency conditions are detected, the system automatically activates the portable information capturing device, eliminating the need for manual activation during critical moments and ensuring timely capture of emergency data.
2Reliability
If the portable information capturing device is activated continuously, then the device is ready to capture data at any time, but power consumption increases and operating session decreases
Solution Approach 1:
Instead of continuous activation, the system employs periodic monitoring of environmental parameters through status sensors. The portable information capturing device remains in a low-power state until specific periodic checks detect emergency conditions, at which point activation occurs. This periodic approach maintains capture readiness while significantly reducing power consumption compared to continuous operation.
3Use of energy by moving object
If the portable information capturing device is kept in shutdown status, then power consumption is minimized, but the device cannot capture data until activated
Solution Approach 1:
The system introduces status sensors as intermediary components that continuously monitor environmental parameters and communicate with the portable information capturing device. These sensors act as mediators, enabling the device to remain in shutdown status for power savings while still detecting emergency conditions through the sensor network, thus maintaining both low power consumption and high capture reliability.
4Ease of operation
If manual activation is required, then the device operates only when explicitly activated, but user response time is insufficient during emergencies
Solution Approach 1:
The system enables self-service operation where the portable information capturing device automatically detects emergency conditions through integrated status sensors and activates itself without requiring manual user intervention. This self-activating capability maintains operational simplicity while dramatically improving data capture efficiency during emergencies by eliminating the human response time bottleneck.
Data Source
AI summary
An environmental surveillance system includes at least one status sensor, a control device, and at least one portable information capturing device. The control device is coupled to the status sensors to send a broadcast packet in accordance with sensing signals generated from the status sensors. The broadcast packet includes a broadcast data. The broadcast data includes an actuation command. The at least one portable information capturing device receives the broadcast packet and compares a match data with the broadcast data in the broadcast packet. When the match data matches the broadcast data, the at least one portable information capturing device starts a media capturing procedure in accordance with the actuation command.
