Method and apparatus for processing signpost signals received by a tag
First Claim
1. An apparatus comprising a tag having circuitry that includes:
- a receiver section configured to receive wireless signpost signals that each include a signpost code;
a further section responsive to receipt by said receiver section of a signpost signal for converting the signpost code from the received signpost signal into location information representative of a physical location of a signpost that transmitted the received signpost signal; and
a transmitter section operable to transmit wireless tag signals that each include a tag code associated with said tag, said transmitter section being responsive to conversion of a received signpost code into location information by said further section for including the location information in at least one said tag signal.

Abstract
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.

10. A method comprising:
-
receiving in a receiver section of a tag wireless signpost signals that each include a signpost code;
responding to receipt by said receiver section of a signpost signal by causing a further section of said tag to convert the signpost code from the received signpost signal into location information representative of a physical location of a signpost that transmitted the received signpost signal; and
transmitting from a transmitter section of said tag wireless tag signals that each include a tag code associated with said tag, said transmitting including causing said transmitter section to be responsive to conversion of a received signpost code into location information by said further section for including the location information in at least one said tag signal. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. An apparatus comprising a tag having circuitry that includes:
-
a receiver section configured to receive wireless signpost signals that each include a signpost code;
a further section responsive to receipt of a signpost signal by said receiver section for determining whether the signpost that generated the received signpost signal is a replacement for a different signpost; and
a transmitter section operable to transmit wireless tag signals that each include a tag code associated with said tag, said transmitter section being responsive to a determination by said further section that the received signpost signal is from a replacement signpost by including in at least one said tag signal an information portion that relates to the signpost replaced by the signpost that generated the received signpost signal. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26)

27. A method, comprising:
-
receiving within a receiver section of a tag wireless signpost signals that each include a signpost code;
responding to receipt of a signpost signal in said receiver section by determining in a further section of said tag whether a signpost that generated the received signpost signal is a replacement for a different signpost; and
transmitting from a transmitter section wireless tag signals that each include a tag code associated with said tag, and responding to a determination by said further section that the received signpost signal is from a replacement signpost by causing said transmitter section to include in at least one said tag signal an information portion that relates to the signpost replaced by the signpost that generated the received signpost signal. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34)
