  • Patent number: 11262964
    Abstract: Described herein are techniques for removing control of a display from an operating system. The disclosed techniques decouple operation of the physical display device from control of the operating system so that the display device may be powered down while not needed during streaming. The device driver for the graphics card, into which a display device cable is plugged, simulates operation of the display but allows the display to be powered down. Simulating the display involves properly responding to queries or commands from the operating system, and generating the signals that would be expected from the display device by the operating system. While simulated in this manner, whether the display device is actually powered down does not matter to the operation of an application being streamed, because the operating system still “believes” the display device is powered on. Thus application streaming is not interrupted by powering down the display device.

  • Publication number: 20220013948
    Abstract: A power coupler includes an input end assembly and an output end assembly separably coupled to the input end assembly. The input end assembly includes an input end base including a slot, a sealing cover arranged at the input end base, an input conductive member arranged at the input end base and connected to an external power supply, and a self-locking structure. The sealing cover is movable between a closing position to cover a slot port of the slot and an opening position to at least partially open the slot port. The self-locking structure is switchable between a locked state to limit the sealing cover from moving towards the opening position and an unlocked state to not limit the sealing cover. The output end assembly includes an output conductive member configured to extend into the slot and be connected to the input conductive member.

  • Publication number: 20210375234
    Abstract: A display system modifies display cycles of one or more displays to perform a system operation while avoiding visual perturbations at the one or more displays. The display system modifies, synchronizes, or both, blanking periods of the one or more displays such that blanking periods equal or exceed a blackout duration and overlap for at least the blackout duration. Then the system performs the system operation during an overlapping portion of the one or more blanking periods, where the system operation reduces availability of display data at the one or more displays.

  • Patent number: 11101645
    Abstract: A power supply system includes a wireless power supply end and a wireless receiving end. The wireless receiving end includes a resonant receiving component and a rectifying and voltage-stabilizing component that is connected to the resonant receiving component to output a voltage-stabilized power supply (VCC). A load sudden-change protection circuit includes an overvoltage protection component and an under-voltage protection component that are each respectively connected to the voltage-stabilized power supply and a load. The overvoltage protection component turns on the load when the voltage of the voltage-stabilized power supply is higher than a first preset voltage due to sudden turn-off of the load. The under-voltage protection component turns off the load when the voltage of the voltage-stabilized power supply is lower than a second preset voltage due to sudden turn-on of the load.
