Digital Assistant Call Sign Detection for Unanswered Police Radio Calls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Police officers may become distracted or busy, leading to delayed responses to calls, and existing digital assistants do not effectively manage device operation when users do not answer calls.
Innovation Solution
A method and apparatus that utilize a digital assistant in a police radio to identify a wake word as a user's call sign, reminding the user of unanswered calls and providing sensor data to the caller if the user does not respond within a predetermined time, while forming a personal-area network with various sensors to monitor and report the officer's conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a police officer is assigned to monitor calls continuously, then response reliability improves, but the officer's availability for other duties decreases
Solution Approach 1:
The system enables self-service by automatically detecting unanswered calls and proactively notifying the officer without requiring continuous manual monitoring. The digital assistant autonomously manages call monitoring and officer notification, freeing the officer from the need to continuously check for calls while maintaining reliable response capabilities.
Solution Approach 2:
The system implements feedback by establishing a communication loop where the digital assistant monitors call status, detects unanswered calls, and provides feedback to the officer through notifications. This automated feedback mechanism ensures the officer is informed of missed calls without needing to continuously monitor the radio, thereby maintaining response reliability while preserving officer productivity.
2Loss of time
If the digital assistant continuously monitors for calls, then call detection timeliness improves, but energy consumption increases
Solution Approach 1:
The system applies periodic action by having the digital assistant check for unanswered calls at specific intervals rather than continuously monitoring. The assistant periodically queries the call status and compares it with the officer's response status, achieving timely call detection while reducing energy consumption by avoiding constant monitoring activities.
3Reliability
If the system provides automated call monitoring and notification, then operational safety improves, but device complexity increases
Solution Approach 1:
The system uses an intermediary approach by introducing a digital assistant as a mediator between the radio communication system and the officer. The digital assistant handles the complex tasks of call monitoring, status detection, and notification generation, while presenting a simple interface to the officer. This intermediary layer manages the system complexity internally while maintaining operational safety and simplicity from the user perspective.

AI summary
A method and apparatus for operating a device when a user does not answer a call is provided herein. During operation a wake word for the device is identified as a user's call sign (a combination of identifying letters, letters and numbers, or words assigned to an officer for use in communication (as in the address of a message sent by radio). The call sign does not comprise a sender or receiver's actual name. When a device detects the wake word as an over-the-air transmission, the device will determine if a user answered the call. If not, sensor data will be provided to the caller and a digital assistant will periodically remind the user of the unanswered call.
