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.

摘要： Systems and methods provide for determining a distance between a signpost and a tag and for locating a tag using multiple signposts. The system uses a signal received at a tag from a signpost, and from them measures the signal strength of the signal with respect to one or more antennas on the tag. The system calculates an RSSI using the measured signal strength, from which a distance can be determined between the signpost and the tag. The system also uses signals received from multiple signposts, to measure multiple signal strengths, resulting in multiple distance determinations corresponding to the various signposts, thereby establishing a location for the tag.

摘要： A tag has a circuit portion that functions as a reader capable of wireless communication with other tags. According to a different aspect, a tag has a circuit portion with first and second modes, the circuitry consuming less power in the second mode than the first mode, and exiting the second mode only in response to an act by a human. According to yet another aspect, a tag can receive wireless communications conforming to one of a cellular telephone network communication protocol, a satellite communication protocol, and a wireless computer network communication protocol. The tag responds to receipt of a predetermined wireless signal conforming to the one protocol by carrying out one of first action that includes causing the tag to enter an electronically secure state, or a second action that includes causing the tag to exit the electronically secure state.

摘要： A tag can receive first and second wireless signals respectively defining first and second transmission fields that overlap. When the tag moves from the first field to the second field through the region of overlap, the apparatus transitions only once from recognizing the tag is in the first field to recognizing the tag is in the second field. According to another aspect, first and second signposts are supported at spaced locations in the region of a crane, and respectively transmit first and second wireless signals that are different, and that respectively define first and second fields of transmission. According to yet another aspect, a signpost transmits wireless signals having a transmission field, and a system senses positional information regarding a tag movable relative to the signpost, the system using the positional information to determine a location of the tag in relation to the transmission field.
