  • Publication number: 20230395122
    Abstract: A memory device includes an array of memory cells and a plurality of peripheral circuits operably coupled to the memory array. A power control circuit may be configured to individually control an application of power to each of the plurality of peripheral circuits and the array of memory cells. Inserting a switch device across the different power domains to achieve the same sequential wake-up path for the peripheral circuits connected to different power domains reduces peak current.

  • Patent number: 11503900
    Abstract: A mist spraying hair brush with retractable bristles includes a brush body, an actuating shaft, a mist spraying assembly, and a housing containing these components. The actuating shaft has a bended portion. When the actuating shaft is rotated and the bended portion pushes the brush body, multiple bristles of the brush body extend out of the housing. The mist spraying assembly has an electric oscillation assembly and an injection portion. The injection portion communicates with the oscillation assembly, such that liquid flows to the oscillation assembly via the injection portion and is atomized into spray. Then the spray flows out of the housing. The mist spraying hair brush with retractable bristles is small in size and is convenient in storage. Moreover, the multiple bristles can retract into the housing, so the multiple bristles will not be bended when carried in a bag full of objects.
