  • Patent number: 9727767
    Abstract: Embodiments of a method for clock synchronization in a radio frequency identification (RFID) equipped device, an RFID equipped device, and a hand-held communications device are described. In one embodiment, a method for clock synchronization in an RFID equipped device involves measuring a difference between a field clock frequency generated from an external clock and an internal clock frequency generated from an internal clock and generating outgoing bits in the RFID equipped device in response to the measured difference. Generating the outgoing bits involves adjusting the bit length of at least one of the outgoing bits in response to the measured difference. Other embodiments are also described.

  • Patent number: 9601268
    Abstract: A circuit for delivering power to a load from a wireless power supply comprises an inductor coil for placing in the electromagnetic field of an inductor coil of a supply and a switchable capacitor bank with capacitors switchable at least between a series and a parallel configuration. The voltage across the capacitor bank is used as a feedback control parameter for controlling the capacitor bank switching. A voltage regulator is used to supply the load with a constant voltage power supply derived from the capacitor bank output.

  • Patent number: 9513609
    Abstract: A method of wireless communication, with a circuit that includes a radio frequency identification (RFID) reader, can be carried out using a circuit that is configured and arranged to communicate with RFID cards that use load modulation of an RF carrier provided by the RFID reader. A presence of the radio frequency (RF) carrier is detected on an antenna. A local clock signal is generated. A difference between the local clock signal and the RF carrier is detected. In response to the detected difference, the frequency of the local clock signal is modified to reduce the detected difference. Load modulation of the RF carrier is mimicked by modulating the local clock signal to encode data; and driving the antenna with the modulated local clock signal.

  • Patent number: 9418249
    Abstract: Transponder (180) having stored a fixed identification number, which expands said identification number with a random number, encrypts said expanded number with a key, and sends it to a reader (160) on its request. Reader (160), which on request receives an encrypted number from a transponder (180), decrypts a received encrypted number with a key, which was also used by the transponder (180), and extracts a fixed identification number associated with the transponder (180).
