    摘要: The invention provides for restoration of lost peer-to-peer offline transaction records. The lost offline transaction records may include access rights to digital media. In one embodiment, a demand for restoration of a plurality of lost peer-to-peer offline transaction records is made. In response, an attempt is made to verify each transaction for the plurality of lost transaction records. This attempt is made through another party to the corresponding transaction. An accuracy indicator is assigned to each transaction to indicate whether the transaction is verified directly through another party to the corresponding transaction. A determination is made as to whether each transaction record of the plurality of lost transaction records should be restored based on the assigned accuracy indicators.

    摘要: A system for tracking RFID tags with a reader device having a plurality of antennas. The antennas are positioned such that portions of at least two of the plurality of antennas physically overlap each other and are in approximately the same plane. A pair of overlapping antennas are also positioned so that an RFID tag is positioned within both signal fields of the pair of overlapping antennas. In addition, the reader device is configured to selectively activate the plurality of overlapping antennas to thereby selectively interrogate one or more of the RFID tags, and the reader device is configured to use the selective interrogation of the one or more RFID tags to track the locations of the RFID tags.

    摘要: In one embodiment of the present invention, a first set of coordinates for a plurality of locations in a symmetric environment is accessed. The first set of coordinates are defined by a position determining system disposed in the symmetric environment which uses a first coordinate system. A second set of coordinates for the plurality of locations in the symmetric environment are accessed. The second set of coordinates are defined by a second coordinate system. The first set of coordinates are correlated with the second set of coordinates. Then, at least one matrix is determined that is useable to convert a set of coordinates defined by the first coordinate system to a corresponding set of coordinates defined by the second coordinate system.

    摘要: A device for limiting access to information corresponding to a context. The device has context logic configured to determine context and a trusted computing platform coupled to the context logic. The trusted computing has a computer readable medium and a filter coupled to the computer readable medium. The filter is configured to receive context from the context logic and retrieve context information from the computer readable medium associated with the context. Thus, the trusted platform limits access to the context information in the database unless context associated with the context information is received.

    摘要: Compensation for tolerances inherent in state-of-the-art locating and targeting. Based upon known approximate position and heading of the spotter, and certain data related to objects with the a vision area, an expanded field of vision related to the perspective of a virtual spotter location is generated. Compensation for present location variance due to locator equipment inherent tolerance is provided such that targeting of each object in the vision area can be precisely implemented.

    摘要: A reader device for locating and tracking multiple tags includes a plurality of closely packed antenna circuits and at least one controller configured to control the plurality of closely packed antenna circuits. The at least one controller is configured to activate one or more of the antenna circuits to generate at least one resonance signal field configured to interrogate at least one tag associated with the one or more active antenna circuits while substantially preventing or reducing cross-coupling of signals between the one or more active antenna circuits and at least one antenna circuit within the at least one resonance signal field to a sufficiently low level, wherein the sufficiently low level substantially prevents misreads from unwanted tags, to thereby track the multiple tags in a substantially controlled manner.
