Title:
PROXIMAL PHYSICAL LOCATION TRACKING AND MANAGEMENT SYSTEMS AND METHODS
Document Type and Number:
WIPO Patent Application WO/2019/029596
Kind Code:
A1
Abstract:
Systems and methods for monitoring the physical proximity of beacon devices relative to a deployment of relay devices. Beacon device may broadcast a proximate data signal receivable relay devices within range. Upon receiving a proximate data signal from a beacon, a relay is configured to provide a corresponding notification to a monitoring server. During standard operation, a beacon device is configured to broadcast the proximate data signal at a first frequency. A beacon may include an emergency trigger, as well as possible optional emergency detection sensors. Upon detecting an emergency, a beacon device broadcasts a proximate data signal at a second frequency and/or modify the proximate data signal. The monitoring server monitors the frequency of transmission and/or content of the proximate data signals from the beacon devices and, upon detecting an emergency (or the absence of an expected proximate data signal from a beacon), may provide an emergency alert.
