Security System EAS Alert Activation via Mobile Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The Emergency Alert System (EAS) faces challenges in effectively notifying subscribers, as mobile devices may be inaccessible or unable to alert users due to being turned off or set to low volume, especially during critical alerts like disasters or emergencies.
Innovation Solution
A system where devices such as cellular phones, PDAs, or computers can activate a security system upon receiving EAS alert messages, determining whether to output the message through an interface or activate the security system if the device is inaccessible, and network providers can also directly activate the security system if a communication session is not established.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If EAS alert messages are broadcast to mobile devices, then subscribers can receive emergency notifications, but the notification may fail if the device is inaccessible or turned off
Solution Approach 1:
The patent introduces a security system as an intermediary component between the mobile device and the EAS alert message delivery. The security system includes a receiver that can independently receive EAS alert messages and an activator that can trigger notifications through alternative channels (visual displays, audio outputs, or other notification mechanisms) when the mobile device is inaccessible or unavailable, thereby ensuring reliable notification delivery without requiring direct mobile device functionality
Solution Approach 2:
The patent implements preliminary action by having the security system continuously monitored and ready to receive EAS alert messages independently of the mobile device state. The system proactively checks device accessibility and prepares alternative notification paths in advance, so that when an EAS alert is received, the notification can be delivered immediately through available channels without waiting for mobile device availability
2Reliability
If the mobile device ringer is turned off or volume is low, then the device remains accessible, but the subscriber cannot be properly alerted to EAS messages
Solution Approach 1:
The security system acts as an intermediary that bypasses the mobile device's audio output limitations. It receives EAS alert messages independently and activates its own notification mechanisms (such as visual displays on the security system interface or audio outputs from the security system speakers) to alert the subscriber, eliminating dependence on the mobile device's ringer or volume settings
Solution Approach 2:
The patent implements dynamic notification delivery by having the security system adaptively select notification methods based on real-time conditions. The activator monitors device accessibility and alert effectiveness, dynamically switching between different notification channels (visual, audio, or combined) to ensure the subscriber is properly alerted regardless of mobile device settings

AI summary
An Emergency Alert System (EAS) alert message may be used to activate a security system. For example, a mobile device of a subscriber may receive an EAS alert message from a network provider of the mobile device. Upon receipt of the EAS alert message, the mobile device may send an indication of the EAS message to the security system. A component of the security system may be activated to provide notification of the EAS alert message to the subscriber.
