Patent ID: 8091790

Claim:
A blister pack, comprising: a base having a plurality of cavities formed therein, each of said cavities holding one of a plurality of products; a sealing sheet provided on top of said base and covering said cavities; a network provided on or within one of said sealing sheet and said base, said network comprising a plurality of RFID chips and being structured to receive one or more RF interrogation signals from a reader device, each of said RFID chips being provided adjacent to a corresponding cavity holding one of said products associated with the chip, said network having one or more conductors provided on or within said sealing sheet and operatively coupling all of said RFID chips, wherein said RFID chips are physically interconnected to one another through said one or more conductors, wherein said one or more conductors individually and substantially or entirely surround each of said cavities such that if any one of the cavities is accessed a portion of the one or more conductors surrounding the cavity will be broken and the network will be rendered not intact, and wherein said network, in response to receiving said one or more RF interrogation signals, provides an indication to said reader device as to whether said network is intact based on: (i) whether one of said RFID chips is able to communicate with all of the other RFID chips of the network through the one or more conductors, or (ii) whether all of said RFID chips of the network are able to receive said one or more RF interrogation signals through the one or more conductors, wherein if said network is intact said network transmits a first response to said reader device in response to said one or more RF interrogation signals, said first response being an indication to said reader device that said network is intact, and wherein if said network is not intact said network in response to said one or more RF interrogation signals either transmits no response to said reader device or transmits a second response to said reader device, said no response and said second response each being an indication to said reader device that said network is not intact.
