  • Publication number: 20200013874
    Abstract: A structure and method for implementation of dummy gate structures within multi-gate device structures includes a semiconductor device including an isolation region that separates a first and second active region. The first active region is adjacent to a first side of the isolation region and the second active region is adjacent to a second side of the isolation region. A device including a source, a drain, and a gate is formed within the first active region. One of the source and drain regions are disposed adjacent to the isolation region. A dummy gate is formed at least partially over the isolation region and adjacent to the one of the source and drain regions. In various examples, the gate includes a first dielectric layer having a first thickness and the dummy gate includes a second dielectric layer having a second thickness greater than the first thickness.

  • Patent number: 10518435
    Abstract: A feeding system with numerically adjustable pneumatic cylinder speeds includes: a frame; an X-axis pneumatic cylinder; a Z-axis pneumatic cylinder; a feeding table connected to the pneumatic cylinders in order to be driven into motion in the X- and Z-axis directions; an X-axis detection module; a Z-axis detection module; a microcomputer; and a display screen electrically connected to the microcomputer. The microcomputer uses each detection module to determine the time interval between the instant at which the piston rod of the corresponding pneumatic cylinder passes the corresponding starting point and a subsequent instant at which the same piston rod passes the corresponding endpoint. The time intervals thus determined are defined as a duration of X-axis forward movement and a duration of Z-axis forward movement respectively. Both durations are displayed on the display screen.

    Abstract: A device generates blended frames, with each blended frame composed of multiple image layers and each image layer composed of multiple regions. The device includes display hardware. The display hardware retrieves a given image layer in a current frame from a memory. Based on at least content hints generated at the display hardware for the given image layer in the current frame, the display hardware makes a determination of whether to skip access to the memory for retrieving each region of each image layer in a next frame that is immediately after the current frame, and accesses the memory for the next frame according to the determination.
