摘要： An electromagnetic field sensor or generator employing a radio frequency microstrip transmission channel formed by a low-loss dielectric substrate sandwiched between a non-resonant microstrip conductor. A discontinuity in said microstrip conductor that substantially alters its cross-sectional dimensions causes electrical signals in the microstrip conductor to be inductively coupled to near field electromagnetic radiation in the vicinity of the discontinuity. The discontinuity may be defined by one or more holes, slots, slits or stubs in the microstrip. The sensor/generator may be used in numerous applications, including NMR spectrometry, as a near field scanning device to inspect operating integrated circuits, or to read or write data on magnetic materials.

摘要： In one embodiment, a method includes accessing at least two determinations of the location of a mobile computing device, with each determined location having been determined without reference to explicit location information manually input by a user of the mobile computing device. At least one first determined location is compared with at least one second determined location, with comparisons being made between location determinations made based on different location determination input. A functionality associated with the mobile computing device is allowed if the first determined location corresponds to at least one of the second determined locations.

摘要： An Integrated Circuit (IC) for an RFID tag includes two electrically isolated antenna ports for connecting to two antennas, with each antenna port configured to operate at a different frequency range and/or with a different communications protocol. In some embodiments a rectifier coupled to one of the antenna ports is operable to extract energy from an electromagnetic field in a first frequency range, and a demodulator coupled to the other antenna port is operable to demodulate symbols according to an RFID protocol in a second frequency range. In some embodiments the frequency ranges are disjoint, intersecting, or one is a proper subset of the other. In some embodiments each port is coupled to its own rectifier and/or its own modulator and/or its own demodulator. In some embodiments an RFID tag includes the IC and two antennas, each operable in one of the two frequency ranges.

摘要： A method of operating a plurality of Radio Frequency Identification (RFID) readers includes operating the readers according to a spatial-division and time-division synchronization schedule. Each reader may be associated with a reader group, and the schedule may specify a duration of time that all of the readers in a group may be active. Readers in different reader groups may be scheduled independent of readers in other reader groups.
