  • Patent number: 11258947
    Abstract: Methods and apparatus for link training and low power operation. A multi-lane high speed bus is optimized for transferring audio/visual (A/V) data at slower rates. In one embodiment, the high speed bus is configured to use a packet format structure that allows for more fluid data delivery times, thereby allowing the high speed bus to deliver A/V data at times selected to reduce power consumption. In another embodiment, the high speed bus is configured to cache link initialization data for subsequent link re-initialization before entering a low power state. Thereafter, when the link exits the low power state, the high speed bus can skip certain portions of link initialization. Still a third embodiment of the present disclosure is directed to exemplary modifications to existing high speed bus link training and low power operation, consistent with the aforementioned principles. Variants of a Universal Serial Bus implementation are provided for illustration.

  • Patent number: 10943557
    Abstract: Systems, methods, and apparatus to transition a display device between operating modes using a single dedicated pin of a circuit connected to the display device. The dedicated pin can receive a packet signal corresponding to an operating mode for the display device, and the circuit can thereafter cause the display device to transition into the desired operating mode in response to receiving the packet signal. The operating mode can be a low power on mode where an interface connected to the circuit is deactivated and at least some circuitry of the display device is throttled or powered off. The display device can be driven in an all black state while in the low power on mode, thereby allowing the display device to more quickly transition out of the low power on mode compared to when the display device is completely off.

  • Publication number: 20190280731
    Abstract: A method for converting source data to a channel-modulated signal having a plurality of pairs of in-phase (I) and quadrature-phase (Q) data in a mobile station, wherein the mobile station uses at least one channel, includes the steps of: a) encoding the source data to generate at least one data part and a control part; b) generating at least one spreading code to be allocated to the channel, wherein each spreading code is selected on the basis of a data rate of the data part and the control part and spreading codes are selected so that two consecutive pairs of the I and Q data are correspondent to two points located on same point or symmetrical with respect to a zero point on a phase domain; and c) spreading the control part and the data part by using the spreading code, to thereby generate the channel-modulated signal.
