  • Patent number: 10868447
    Abstract: Methods and apparatus for determining the misalignment and mutual coupling between the transmitter coil and receiver coil, with or without an intermediate relay resonator coil, of a wireless power charging system are provided. The determination can be made without using any direct measurement from the receiver circuit. The technic involves exciting the transmitter coil of the wireless power charging system at several frequencies with equal or different input voltage/current, such that the number of equivalent circuit equations is at least equal to the number of unknown terms in the equations. The methods use the knowledge of only the input voltage and the input current of the transmitter coil. This means that the mutual inductance or magnetic coupling coefficient between the transmitter and receiver coils can be determined based on the information obtained from the transmitter circuit and there is no need for any wireless communication from or direct measurements of the receiver circuit.

    Abstract: A source device being associated with an account uses playback of a media content item to cause a target device to become associated with the account. The target device enters an association mode and records a portion of the playing content. The target device provides the recording to a server that identifies the song (e.g., using a music fingerprint service) and uses the identification of the song to find the account that caused playback of the identified song. With the account identified, the server provides credentials of the account to target system. The target device accesses content or services using the account. As confirmation of receiving the credentials, the server causes playback of the content to transition to from the source device to the target device.

  • Patent number: 10798550
    Abstract: A controller of a terminal device controls the terminal device in a second control mode in which the terminal device operates in cooperation with the vehicle when the controller determines that the vehicle-mounted device is in the range of the distance in which the short-range wireless communication with the terminal device is possible in a case in which the controller is controlling the terminal device in the first control mode. The controller controls the terminal device in the first control mode when the controller determines that the vehicle-mounted device is not in the range of the distance in which the short-range wireless communication with the terminal device is possible in a case in which the controller is controlling the terminal device in the second control mode.

  • Patent number: 10796111
    Abstract: A method begins by a radio frequency identification (RFID) reader transmitting a first and second radio frequency (RF) signal of a plurality of RF signals, which each include a unique carrier frequency and an instruction to an RFID tag to respond with a received power level indication. The method continues by the RFID reader receiving, in response to the first and second signals sent at a first and second carrier frequency, a first and second response from the RFID tag that includes a first and second received power level indication. The method continues by the RFID reader determining an estimated resonant frequency of the RFID tag based on the first and second received power level indications and the first and second carrier frequencies. The method continues by the RFID reader determining an environmental condition based on the estimated resonant frequency.

  • Patent number: 10785627
    Abstract: Embodiments of this specification provide a method and apparatus for quick enabling a service in an application program and an electronic device. When a user terminal receives tag content transmitted by a near field communication (NFC) tag, an operating system of the user terminal may enable an application program that has registered NFC. Then, the enabled application program uploads the tag content to a server. According to a service routed by the server after the server decodes the tag content, the application program executes the routed service.
