  • Patent number: 10141967
    Abstract: A mobile device receives a message from a vehicle computing platform via remote process communication (RPC), updates an origin address of the message to indicate the mobile device, sends the message to a destination address of the message, receives a response message from the destination, updates a destination address of the response message to indicate the computing platform, and sends the response message to the computing platform via the RPC. A computing platform constructs a remote procedure call (RPC) message by a virtual network interface application for a request received from a vehicle application for a network protocol unsupported by a mobile device, and sends the RPC to the mobile device to cause the mobile device to update an origin address of the request to indicate the mobile device and send the request to a destination address of the request.

  • Patent number: 10135650
    Abstract: A circuit for tuning a resonance frequency of an electrically small antenna. The circuit includes a first source configured for providing a modulation signal, a second source configured for providing a periodic electrical signal, an antenna, and a tuning circuit configured for modulating a resonance frequency of the antenna in response to the modulation signal. The tuning circuit includes first and second capacitors that are alternately coupled to the antenna to change the resonance frequency of the antenna. The capacitor currently coupled to the antenna is decoupled from the antenna and the other capacitor is coupled to the antenna when the voltage across the capacitor currently coupled to the antenna is momentarily zero. In an exemplary embodiment, the tuning circuit comprises first and second inductors rather than capacitors. The inductors are switched into and out of the circuit when the current through the currently coupled inductor is momentarily zero.

  • Patent number: 10122395
    Abstract: A first local oscillator generates a modulation signal of a predetermined frequency. A second local oscillator outputs a local oscillation signal frequency-modulated by using the modulation signal from the first local oscillator. A quadrature detection unit subjects an FM signal to quadrature detection by using the local oscillation signal output from the second local oscillator and outputs a base band signal. A first reduction unit and a second reduction unit reduce a direct current component contained in the base band signal. A correction unit restores the direct current component by correcting the base band signal such that the base band signal is centered around an origin of a polar coordinate system on an IQ plane. An FM detection unit subjects the corrected base band signal to FM detection and generates a detection signal.
