Abstract
An object location tracking system for tracking a movable object includes a plurality of beacons spatially distributed within a building, each beacon transmitting a respective ID signal, at least one transceiver device which receives the transmission of ID signals from the beacons and determines received signal strengths of such transmissions, the transceiver device adapted to be attached to the movable object, a motion detector coupled to the at least one transceiver device configured to provide information relating to a motion of the at least one transceiver device, and a processing module that uses information reflective of the received signal strengths of the transmissions received by the transceiver device, in combination with information reflective of the motion of the at least one transceiver device, to determine a current location of the transceiver device.
