  • Patent number: 10377346
    Abstract: A system and method of providing one or more vehicle functions at a vehicle, the method including: when the vehicle is in a powered off state, periodically scanning for short-range wireless communication (SRWC) devices using a SRWC chipset and, as a result of the scanning, receiving a connection request from a mobile device; in response thereto, establishing a SRWC connection with the mobile device using the SRWC chipset; after establishing the SRWC connection, authorizing the mobile device to access one or more vehicle functions; then, performing an initialization suite of operations, wherein the initialization suite of operations includes initializing at least one vehicle system module, and wherein the initialization suite of operations is performed in response to a predictive user determination indicative of an imminent user interaction with the vehicle; and executing the initialization suite of operations at the vehicle.
    Type: Grant

  • Patent number: 10360927
    Abstract: The present document discloses a method and apparatus for compensating for a lost frame in a transform domain, comprising: calculating frequency-domain coefficients of a current lost frame using frequency-domain coefficients of one or more frames prior to the current lost frame, and performing frequency-time transform to obtain an initially compensated signal; and performing waveform adjustment, to obtain a compensated signal. Alternatively, extrapolation is performed for all or part of frequency points of the current lost frame using phases and amplitudes of corresponding frequency points of a plurality of previous frames to obtain phases and amplitudes of the corresponding frequency points of the current lost frame, to obtain frequency-domain coefficients of the corresponding frequency points, and frequency-time transform is performed to obtain a compensated signal.
