Portable Device Emergency Beacon via Voice Pattern Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In emergency situations, it is challenging to convey precise location information and indicate the need for help when conventional methods, such as pressing a dedicated emergency button, are not accessible on portable communication devices.
Innovation Solution
A portable device equipped with a location receiver, recognition modules for usage-related inputs, and a processor that can derive location information and transmit an emergency indication when specific programmed keys or patterns are detected, such as voice inputs or keypad combinations, to automatically trigger an emergency beacon.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated emergency button is provided on the portable device, then emergency situations can be detected and location information transmitted, but the device complexity increases and the button may not be readily accessible in emergency situations
Solution Approach 1:
The patent applies multi-functionality by enabling the portable device to detect emergencies through multiple existing functions: voice recognition, keypad input patterns, and usage behavior analysis. This eliminates the need for a dedicated emergency button while maintaining reliable emergency detection capability through alternative accessible interfaces.
Solution Approach 2:
The device monitors its own usage patterns and automatically detects emergency situations based on predefined criteria such as unusual keypad sequences, specific voice commands, or abnormal usage behavior. This self-monitoring capability allows the device to trigger emergency beacon transmission without requiring a separate dedicated button or external intervention.
2Ease of operation
If voice or usage-related inputs are used to detect emergencies, then the emergency button accessibility problem is solved, but the difficulty of detecting and measuring emergency situations increases due to pattern recognition requirements
Solution Approach 1:
The patent implements preliminary action by pre-programming specific voice commands, keypad patterns, and usage behavior criteria that indicate emergency situations. The device is configured in advance with these detection parameters, allowing it to automatically recognize and respond to emergencies without requiring complex real-time analysis or user expertise in pattern recognition.

AI summary
In one embodiment, an apparatus can include: (i) a location receiver configured to receive position signals, and to derive location information therefrom; (ii) one or more recognition modules configured to receive usage-related inputs, and to provide a pattern therefrom; and (iii) a processor configured to receive the pattern, and to provide the location information and an emergency indication. For example, particular embodiments can advantageously provide an emergency beacon using voice or other usage-related inputs to a cellular telephone.
