Abstract:
A real-time location system (RTLS) uses transmitting and listening tags, bridges, and beacons. The fixed beacons broadcast BLE advertisements containing motion-status information about recent history of perceived motion in. a room as determined from a motion sensor in the beacon. The bridges forward the beacon's received advertisements to a location engine, which records timestamps of motion events seen by each beacon in each room. One or more tags then report their own motion status based on a tag-based accelerometer. The system utilizes a series of location-engine steps, to estimate the room-location of the tags based on a specific combination of RSSI analysis, and a comparison of tag-motion history to the perceived arid recorded motion-status in a room. This analysis of tag-motion history and motion-in-room status produces a better estimate of room-level location of the tag than can be estimated by simple proximity or multi-lateration using radio signal strengths.

Claim (Index 4):
A method for providing people and asset-tag locating using a real-time location system (RTLS) having tags, beacons, bridges, and a central location server comprising the step of:\n transmitting from at least one fixed beacon a Bluetooth low energy (BLE) beacon-advertisement; detecting motion in the vicinity of the at least one beacon using a first motion sensor; transmitting wireless beacon-advertisements from the at least one beacon, to one or more bridges, containing a report of motion history seen in the beacon's room; receiving tag-advertisements at the at least one bridge from the at least one tag; and measuring multiple characteristics of the received tag-advertisements, including received signal strength and tag-motion reports for determining tag location.
