Abstract:
The present invention relates generally to a real-time location system (RTLS) having tags, bridges, bay-level event sensors and a location engine. To determine which bay a tag is in, bay-level event sensors sense motion events in the bay, transmit the motion event reports to a location engine, and/or tags. Tags contain an accelerometer, to sense motion of the tags. A series of location-engine steps estimates the bay-level-location of the tags based on a combination of received signal-strength analysis, and a comparison of tag-motion status to the perceived motion events in a bay. The analysis of tag-motion status and motion-in-bay events produces a better estimate of bay-level location of the tag than a received-signal-strength estimate can produce alone.

Claim (Index 18):
A real-time location system (RTLS) having tags, bay-level event sensors, bridges, and a location server for providing people and asset-tag locating, comprising:\n at least one bay-level event sensor for transmitting Bluetooth low energy (BLE) transmissions, equipped with sensor that detects motion events, and transmitting recent history of motion events sensed in the bay-level-event-sensor's bay; at least one bridge for receiving location-update messages from at least one tag and measuring multiple characteristics of the received location-update messages, including received signal strength; at least one tag for listening for BLE advertisements from the bay-level event sensors and measuring multiple characteristics of the received advertisements, including received signal strength and a series of advertisements of motion events in the bay-level-event-sensor's bay, where accelerometer-sensed-motion status of the tag is compared to the motion events in the bay-level event sensors' transmissions, and location-update messages are transmitted to the at least one bridge; a location engine utilizing location-determining methods comprising:\n a first location method for calculating a first location estimate for the at least one tag, based on radio characteristics of BLE bay-level event sensor signals emitted by at least one bay-level event sensor in fixed locations and received by the at least one tag, and transmitted to the central location server; \n a second location method for calculating a second location estimate for the at least one tag, based on comparing motion events in the bay-level-event-sensors' bays, and the coincident accelerometer-determined motion status of the at least one tag that is likely in the bay; and \n a third location method for combining the first location estimate and second location estimate to determine a location result for the at least one tag.
