Abstract: A framework structure for controlling an RFID device including a platform comprising an RFID radio. The structure comprises a layered framework including a first layer, with at least one functional module comprising a device driver, communicatively coupled with the platform; and a second layer, with at least one functional module comprising an API, communicatively coupled with the first layer and with an application for controlling the RFID device.

Abstract: A phase shifting diode detector system for an RFID reader. Quarter-wave delay circuitry is coupled between a forward transmitted signal of the RFID reader applied at a first end of the delay circuitry, and a reflected signal returning from an RFID tag applied at a second end of the delay circuitry. The system includes a pair of diode detector bridges, each comprising a series-coupled diode pair configured such that diode polarities in each bridge are reversed relative to the output thereof, to produce opposite rectified signal output polarities. An input to each of the bridges is capacitively coupled, from the junction between each said diode pair, to a respective opposite end of the delay circuitry.

Abstract: A system and method generate an extended memory RFID tag by reading data from a memory of a plurality of RFID tags, each including tag identification information stored thereon. The data is combined, in accordance with the tag identification information stored on at least one of the RFID tags, to generate the extended memory RFID tag. Sequencing indicia may be stored in memory in each of a plurality of RFID tags to allow the data to be combined, in accordance with the sequencing indicia.

Abstract: A system and method for defining one or more operating characteristics of a communication device with data is disclosed. In one embodiment, the communication device includes an input port configured to receive a data file that includes information that defines at least one communication protocol for the communication device, and the communication device includes a data file interpreter configured to alter operation of a radio in the communication device in accordance with the at least one communication protocol. In variations, the communication device includes an RFID tag reader coupled to the radio portion, and the tag reader segment is configured to read tag-data received via the radio. In these variations, the data file interpreter is configured to alter operation of the RFID tag reader in accordance with information in the data file, which defines, at least in part, a syntax for RFID reader commands.

Abstract: An RFID reader for communicating with an RFID tag and with a remote RF transceiver. A single transceiver is employed for communicating with RFID tags and with a remote RF transceiver. A single antenna is coupled to the transceiver. In a first mode, the transceiver communicates with the RFID tags via the antenna, on a first frequency. In a second mode, the transceiver communicates with the remote RF transceiver via the same antenna, on the first frequency or a second frequency.

Abstract: Systems and methods for configuring an RFID tag reader based upon one or more aspects of an environment of the RFID tag reader are disclosed. In one embodiment, a tag reader is deployed into an environment that includes at least one readable RFID tags capable of storing dynamic data, and a characteristic of the environment of the tag reader is identified. Based upon the identified characteristic, the configuration of the tag reader is adjusted. In variations, the tag reader is configurable based upon information received from at least one RFID tags.

Abstract: An electronic tag assembly (100) includes a substrate (102) having an antenna pattern (104, 106) disposed thereon, an integrated circuit die (108) having electrical interface terminals (204, 206) that directly contact or interface with the antenna pattern (104, 106), and electrically non-conductive adhesive (202) interposed between the substrate and the integrated circuit die (108) that secures both together, and that maintains the integrity of the electrical interface. Preferably, a clamping force is exerted on the integrated circuit die (108) to maintain contact between the electrical terminals (204, 206) and the antenna pattern (104, 106) while the non-conductive adhesive (202) is being introduced.
