Abstract
An apparatus (10, 240, 300) includes a signpost (11, 241-256, 322, 612, 623, 626-628, 652, 661, 682, 686, 703) which transmits relatively low frequency signpost signals that contain a signpost code and are fundamentally magnetic, a beacon tag (12, 271-275, 301-316, 395-397, 616-618, 641-643, 653, 656-657, 662-664, 679, 708, 711) which receives the signpost signals and transmits radio frequency signals containing the signpost code (42, 93), and a reader (13, 261, 319, 521-530) which receives the radio frequency signals. One of the signpost and tag is mounted on a moveable item to be tracked, and the other is mounted on a similar item or is stationary. A sensor (32) can be provided to detect the presence of an item and cause the signpost to change its transmitted signpost code. The tag can vary the duration, transmission rate, and/or transmission power of its beacon signals.; A control system (14, 500) responsive to the reader can cause the signpost to vary its signpost signal in a manner which causes the tag to shift between normal and low power modes, or which causes the tag to vary at least one operational characteristic, such as transmission rate, transmission power, a transmitted password, or various transmitted codes.
