Abstract: SYSTEM AND METHOD FOR HUB-MANAGED ROTATION OF WEARABLE DEVICES TO PROVIDE CONTINUOUS GAP- FREE PERSONAL EMERGENCY RESPONSE SERVICE A rotation-based continuous monitoring system for providing gap-free fall detection and emergency response monitoring in personal emergency response systems. The system comprises a hub controller and at least two wearable sensing devices configured for sequential rotation between active monitoring and standby charging roles. The hub controller enforces a time-sliced rotation protocol with proactive validation of standby units and atomic role transition maintaining measured switchover gap of zero milliseconds through concurrent overlap periods during which both devices are simultaneously worn at spatially separated body locations. A spatial diversity analysis module analyzes motion data from devices positioned at separated body locations, computing inter-device correlation coefficients to distinguish isolated limb motion from coordinated whole-body motion, thereby suppressing false positive fall alerts while maintaining high fall detection sensitivity while reducing false positive alerts. A biometric continuity verification module extracts multi-modal biometric features comprising pulse- based identification characteristics, gait identification patterns, and contact pressure features to prevent wrong-user monitoring in multi-person households. Wearable devices implement passive optical sensor node architecture, transmitting raw sensor data to the hub for centralized processing. The system executes fall detection processing locally on edge computing processor with response time sufficiently low to provide real-time emergency indication without requiring internet connectivity or cloud services.
