Communication Device Emergency Signal Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing emergency signal systems often result in false alarms due to premature or unnecessary activation, leading to wasteful energy consumption and potential safety risks, especially in situations where the user is threatened for an extended duration.
Innovation Solution
A method that compares input from sensors on a communication device with stored data only in response to an emergency signal, filtering out false alarms and delaying or canceling contact with an alarm responder unless a match is confirmed, thereby conserving energy and ensuring safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If contact with alarm responder is made immediately upon emergency signal, then user safety is ensured, but false alarms cause unnecessary energy waste and alarm responder burden
Solution Approach 1:
The system performs preliminary verification by comparing sensor input against stored data patterns before initiating contact with the alarm responder. This preliminary action filters out false alarms caused by unintended sensor activations, ensuring that energy is only consumed for legitimate emergency situations while maintaining rapid response capability for true threats.
2Reliability
If comparison with stored data is performed continuously, then false alarms are filtered, but energy consumption increases
Solution Approach 1:
The comparison with stored data is performed periodically or event-triggered rather than continuously. The system activates the comparison process only when an emergency signal is detected, allowing the communication device to conserve energy during normal operation while maintaining effective false alarm filtering when needed.
3Reliability
If operator intervention is used to verify emergency signals, then false alarms are prevented, but response time is delayed and costs increase
Solution Approach 1:
The system performs self-verification by automatically comparing sensor input against stored data patterns without requiring operator intervention. This self-service capability prevents false alarms through automated filtering while maintaining rapid automated contact with alarm responders, eliminating both the time delay and cost associated with human operator verification.
4Productivity
If automated filtering without operator review is implemented, then response time is reduced, but false alarm accuracy may decrease
Solution Approach 1:
The automated system performs preliminary verification by comparing real-time sensor input against pre-stored data patterns before triggering an emergency response. This preliminary automated filtering maintains high response speed while achieving accurate false alarm detection through pattern matching, eliminating the need for slower operator review.

AI summary
The invention relates to a method comprising the steps of: - (a) storing data by means of storage means; - (b) receiving input with a sensor of a communication device. The method further comprises of - determining with comparing means in response to an emergency signal an outcome of a comparison of the received input to at least a part of the stored data; and - determining subject to the outcome whether communication means of the communication device must be activated so as to make contact with an alarm responder.
