  • Publication number: 20190189222
    Abstract: A memory device is disclosed in the present invention, comprising a memory array, a logic circuit, a sense amplifier circuit and a read buffer. The logic circuit is configured to perform a read operation in response to a read command and a start address. During the read operation, the logic circuit finds a target data in the memory array. The sense amplifier circuit is configured to read the target data from the memory array during the read operation. The read buffer is configured to temporarily stores and outputs the target data during the read operation. When an interruption event occurs during the read operation, the read buffer preserves a buffer content of the read buffer, and the logic circuit records a read status.

  • Publication number: 20190073300
    Abstract: A nested wrap-around technology includes an address counter and associated logic for generating addresses to perform a nested wrap-around access operation. The nested wrap-around access operation may be a read or a write operation. A wrap-around section length and a wrap-around count define a wrap-around block. A wrap starting address, initially set to a supplied start address, is offset from a lower boundary of a wrap-around section. Access starts at a wrap starting address and proceeds in a wrap-around manner within a wrap-around section. After access of the address immediately preceding the wrap starting address, the wrap starting address is incremented by the wrap-around section length, or, if the wrap-around section is the last one in the wrap-around block, the wrap starting address is set to the lower boundary of the wrap-around block plus the offset. Access continues until a termination event.

  • Publication number: 20180370067
    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.

  • Patent number: 10112672
    Abstract: A frame mechanism for a vehicle with at least three wheels includes wheel frame assemblies to support a vehicle frame assembly. By a shock absorbing assembly, a swing arm, two synchronizing levers and two linking shafts, when any kind of loading carried and external forces are applied to the vehicle, the wheels can constantly remain on the ground surface with the same traction so as to minimize the risk of yaw, drift and unbalance upon a turn or braking of the vehicle. Also, a variety of uneven movements of the wheels can be balanced and converted into a movement of the vehicle frame assembly in an up-and-down direction. In case of the wheels running off the ground, the wheels can be kept in a proper position for retouching down with safety and comfort.
