Mobile Emergency Response via Cell Phone and Local Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Personal Emergency Response Systems (PERS) are inadequate for highly mobile individuals, as they are typically limited to specific locations, and require specialized transmitters for emergency assistance.
Innovation Solution
Integration of cell phone technology and public safety devices with location-based systems, allowing users to activate emergency alerts using their personal wireless devices, which search for and activate nearby emergency indicating or response devices, such as AEDs or emergency phones, based on their specific profiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional PERS use specialized transmitters and are limited to specific locations, then reliability of emergency response is improved, but adaptability to mobile individuals deteriorates
Solution Approach 1:
The patent applies universality by enabling any cell phone to function as a PERS transmitter, eliminating the need for specialized devices. The system allows universal access to emergency services through standard mobile phones, thereby improving adaptability to mobile individuals while maintaining response reliability through the established cellular infrastructure and location tracking capabilities.
2Measurement precision
If specialized transmitters are required for emergency assistance, then measurement precision of emergency location is improved, but device complexity increases
Solution Approach 1:
The patent extracts the essential location tracking and emergency alerting functionality from specialized PERS transmitters and relocates it to standard cell phones. By taking out the core functions (location determination, emergency signal transmission, and response coordination) and implementing them through existing mobile infrastructure, the system achieves precise location measurement without requiring complex specialized devices.
Data Source
AI summary
A personal emergency response system oriented to mobile individuals uses cell phones or other wireless devices as sources of an emergency indicating signal. A personal profile associated with that signal can be evaluated, along with location information to determine which emergency device(s) should be activated and which local messages should be produced to alert other individuals in the area as to the existence of an emergency.
