Control tag with environmentally selected conditional response

摘要

Systems (100) and methods (300) for selective device responsiveness using a plurality of control tags (132) affixed to a plurality of objects (102). The methods involve: receiving, by a plurality of control tags, a reporting command signal sent from an interrogation device via a communications link; and communicating a response to the reporting command signal from only those of the plurality of control tags which are (1) currently being moved, (2) have been moved within a first specified period of time, and/or (3) have a surrounding environment with at least one characteristic that has recently changed.

1. A method for selective device responsiveness using a control tag attachable to an object, comprising:
receiving, by the control tag, a reporting command signal sent from an interrogation device via a communication link; obtaining information indicating whether the control tag should respond to the reporting command signal, where the information indicates that at least one of the following conditions does or does not exist based on sensor data acquired from sensing operations performed by the control tag or sensors coupled to the control tag: (1) the control tag is currently being moved; (2) the control tag has been moved within a first specified period of time; and (3) a characteristic of a surrounding environment has changed within a second specified period of time; communicating a response signal from the control tag to the interrogation device when the information indicates that at least one of the conditions (1), (2) and (3) does exist; and ignoring the reporting command signal such that the response signal is not sent from the control tag to the interrogation device when the information indicates that the conditions (1), (2) and (3) do not exist.
