Abstract: A ribbon comprises a substrate, and a plurality of radio frequency identification (RFID) seals on the substrate. Different RFID seals detune in response to differing tensile loads.

Abstract: A radio frequency identification seal comprises an antenna including a main antenna portion and at least one break-away portion and an RFID tag coupled and tuned to the antenna. The RFID tag outputs a signature in response to a scanning signal when tuned to the antenna.

Abstract: A communications system comprises a record management system storing personal records relating to individuals registered with the record management system and a wireless device carried by at least one of the registered individuals. The wireless device provides an identifier signifying that the individual is registered with the record management system.

Abstract: A communication system (10) comprises at least two communication networks (20, 22) over which communications between physical devices (14) connected to the communication networks are to be carried out. The communication networks (20, 22) implement different protocols for messaging. A communication server (12) acts between the communication networks. Messages between the communication networks pass through the communication server. The communication server includes a knowledge base (286) storing protocol conversion information. The communication server (12) accesses the protocol conversion information in the knowledge base (286) upon receipt of a message and converts the protocol thereof to a protocol compatible with the communication network to which the message is being sent.

Abstract: A cashierless shopping store includes a plurality of shopping carts into which selected items to be purchased are placed by shoppers. Each of the shopping carts includes a weight detector to measure the weight of items placed therein and a transmitter to transmit the measured weights over a wireless communications link. A portable wireless shopping terminal accompanies each of the shopping carts. Each shopping terminal reads item price and item weight data from each selected item to be purchased and receives the measured weight of each selected item transmitted over the wireless communication link by the transmitter. The shopping terminal compares the read item weight data with the transmitted measured weight to determine if the read item weight data and the transmitted measured weight for each selected item correlate.
