  • Patent number: 8917163
    Abstract: An active electronic tag for a memory card is disclosed herein. The active electronic tag includes an antenna, a first amplifier, an automatic gain control circuit, a phase synchronization locking circuit, a decoding and TX/RX control unit and a second amplifier. The antenna receives a detecting signal transmitted from a card reader, in which the detecting signal is carried on a first carrier. The phase synchronization locking circuit generates a positive carrier and a negative carrier with a phase difference of 180 degree. The decoding and TX/RX control unit generates a response signal, which is carried on the negative carrier. By utilizing the phase difference of the first carrier and the negative carrier, the response signal cancels the first carrier on the card reader, so as to transmit the information saved inside the active electronic tag.

  • Patent number: 8915439
    Abstract: Laser scanning module employing a scan mirror and magnet rotor subassembly supported by a stationary stator structure. The scan mirror and magnet rotor subassembly includes: a silicone frame having a pair of silicone torsional hinges (i.e. posts) aligned along a scan axis and a supported by a pair of support elements associated with the stator structure, to support the scan mirror and magnet rotor subassembly. When the scan mirror and magnet rotor subassembly is rotated about its scan axis, by forces generated by an electromagnetic coil structure acting on the permanent magnet mounted on silicone frame, the silicone torsional hinges are elastically distorted and generate linear restoring forces which return the rotor subassembly back to its home position about the scan axis.

  • Patent number: 8844814
    Abstract: A radio frequency identification automatic detecting system with an antenna net includes a radio frequency identification module, an enhancing surface wave-guide coaxial cable structure including a coaxial cable having at least one aperture region without an outer conducting layer, a receiving apparatus having a plurality of receiving spaces and a plurality of extension wires disposed adjacent to the receiving spaces and coupled or connected to the outer conducting layer of the coaxial cable. The electromagnetic field is formed in nearby regions adjacent to the receiving spaces because the electromagnetic wave caused by the current generated from the radio frequency identification module is transmitted by the outer conducting layer and extension wires. The radio frequency identification electronic tag on the object is triggered automatically when the object is moved toward or moved out from the respective receiving space such that the automatic detecting effect is achieved.

  • Patent number: 8840023
    Abstract: An antenna extender configured to be coupled electromagnetically to an RFID read/write station. The extender includes a first circuit oscillating at variable frequency and a second oscillating circuit coupled to the first oscillating circuit, and a processing unit which is powered by energy supplied by the second oscillating circuit when the extender is placed close to the read/write station. The processing unit includes a mechanism to measure voltage at terminals of the second oscillating circuit and a controller that can be used to vary resonance frequency of the first oscillating circuit as a function of the value of the measured voltage to optimize frequency tuning between the extender and the read/write station.

    Abstract: A method of operating a contactless integrated circuit (IC) card reader includes calculating a first transition time of at least one first magnetic pulse during a first transition interval and calculating a second transition time of a second magnetic pulse during a second transition interval. The first transition time is calculated in a calibration phase, and the second transition time is calculated in a detection phase. A contactless IC card is determined to be within a communication rage of the reader based on a comparison of the first and second transition times.

  • Publication number: 20140263648
    Abstract: Some battery-powered devices, such as smartphones, can be unlocked with use of wearable NFC (Near Field Communication) authentication devices. However, using conventional NFC authentication procedures is expensive in terms of power consumption because of continual rediscovery and reauthentication of the wearable authentication device. To address this, the present inventors, devised, among other things, more efficient methods for authenticating NFC-tagged authentication device, such as rings. For example, one embodiment uses two NFC polling loops or structures, instead of one as conventionally done. The first loop, used for initial authentication, entails scanning for two or more types of NFC tags. And the second loop, invoked after initial authentication, scans for a smaller subset of the two or more types to conserve battery power.

  • Publication number: 20140239067
    Abstract: In one or more embodiments described herein, there is provided an apparatus configured for use with one or more directional antennas. The one or more directional antennas each have a respective directional axis, a first sensitivity region being proximal to the directional axis and associated with a first variation in sensitivity across the first region, and a second sensitivity region being distal to the directional axis and associated with a second variation in sensitivity across the second region. The second variation in sensitivity is greater than the first variation in sensitivity. The apparatus is configured to discriminate one source of radio frequency identification signalling at a particular angular position from other neighbouring sources of radio frequency identification signalling by using the alignment of one or more second sensitivity regions with respect to the particular angular position.
