METHOD AND APPARATUS FOR WIRELESS MANAGEMENT OF ARTICLES
First Claim
1. A method implemented by a master RFID tag, the method comprising:
- transmitting at least one first RFID read signal to a plurality of RFID tags local to the master RFID tag;
receiving a first RFID response signal from each of the plurality of RFID tags in response to the at least one first RFID read signal, each of the first RFID response signals comprising an identifier associated with an article;
maintaining an article record indicating at least one expected article that is to be managed by the master RFID tag;
comparing each of the identifiers with the article record in an attempt to compile contextual information associated with the article record; and
transmitting a master signal comprising the contextual information associated with the article record.

Abstract
The present invention is directed to method and apparatus for wireless management of articles. The method is implemented by a master RFID tag. The method includes transmitting at least one first RFID read signal to a plurality of RFID tags local to the master RFID tag and receiving a first RFID response signal from each of the plurality of RFID tags in response to the at least one first RFID read signal. Each of the first RFID response signals comprises an identifier associated with an article. The method further includes maintaining an article record indicating at least one expected article that is to be managed by the master RFID tag and comparing each of the identifiers with the article record in an attempt to compile contextual information associated with the article record. Finally, the method further includes transmitting a master signal comprising the contextual information associated with the article record. Embodiments of the present invention are also directed to a master RFID tag comprising a first communication unit, a memory unit, a processing unit and a second communication unit.
