摘要： A tag has circuitry that can transmit and receive wireless signals, including receipt of first and second wireless signals that are different. The circuitry responds to a predetermined event by inhibiting wireless transmissions for up to a selected time interval, while waiting for receipt of one of the first and second wireless signals. The circuitry responds to receipt during the selected time interval of one of the second wireless signals before receipt of one of the first wireless signals by continuing to inhibit wireless transmissions, and responds to expiration of the selected time interval without receipt of either of the first and second wireless signals by transmitting a selected wireless signal.

摘要： A tag receives a wireless signpost signal that contains a signpost code, converts the signpost code into location information representative of a physical location of a signpost that transmitted the received signpost signal, and transmits a wireless tag signal that includes the location information. In a different configuration, a tag receives a wireless signpost signal that includes a signpost code, and determines whether the signpost that generated the received signpost signal is a replacement for a different signpost. If it is a replacement, the tag transmits a wireless tag signal containing an information portion that relates to the signpost replaced by the signpost that generated the received signpost signal.

摘要： An apparatus (10, 240, 300) includes a signpost (11, 241-256, 322, 612, 623, 626-628, 652, 661, 682, 686, 703) which transmits signpost signals (24) that are received by a tag (12, 271-275, 301-316, 395-397, 616-618, 641-643, 653, 656-657, 662-664, 679, 708, 711). The tag in turn transmits radio frequency beacon signals (72) which are received by a reader (13, 261, 319, 521-530). The tag can vary the duration of the beacon signals, for example in dependence on whether it is currently receiving a signpost signal. Further, the tag can dynamically vary the transmission rate and/or transmission power of the beacon signals, for example following receipt of a signpost signal. Varying these parameters can facilitate compliance with governmental regulations.
