  • Publication number: 20240280116
    Abstract: A buffer assembly includes a screw rod, a base, a rotating element and a clamping ring. The rotating element is rotatably disposed on the base along a rotation axis. The rotating element includes a through hole. The clamping ring is detachably connected to the rotating element along a connection axis, so that the clamping ring is adapted to switch to a connected state or an open state. The clamping ring includes a position-limiting space, and the rotation axis is perpendicular to the connection axis. When the clamping ring is in the connected state, the position-limiting space and the through hole are located on the rotation axis, and the screw rod pushes the clamping ring to rotate so that the screw rod passes through the position-limiting space and the through hole. When the clamping ring is in the open state, the position-limiting space is misaligned with the rotation axis.

  • Patent number: 9201483
    Abstract: An image processing unit including an always on circuit block and a non-always on circuit block is provided. When operating under a first operation mode, the non-always on circuit block receives a bias voltage from a power supply unit, so as to perform an image processing operation on an image input signal. When operating under a second operation mode, the non-always on circuit block stops receiving the bias voltage from the power supply unit, so as to stop the image processing operation, and at least a microcontroller of the non-always on circuit block is powered down. One of the always on circuit block and the non-always on circuit block controls the power supply unit to stop supplying the bias voltage to the non-always on circuit block according an event trigger signal, such that the non-always on circuit block enters the second operation mode from the first operation mode.

  • Publication number: 20070229486
    Abstract: An apparatus and a method for detecting the sync signal of a data signal are disclosed. The apparatus includes a clamping unit, a subtraction unit and a detection unit. The clamping unit receives the data signal and varies the level of the data signal. The subtraction unit coupled to the clamping unit subtracts the level of the data signal from that of the output of the clamping unit and then outputs the subtracting result. The detection unit coupled to the subtraction unit detects the subtracting result from the subtraction unit and judges the sync signal in the data signal accordingly.
