    摘要: A power supply comprises an input voltage detector that detects a drop in input voltage that corresponds to an input voltage loss. A power converter is coupled to the input voltage detector. The power converter, which may be a boost converter or a power factor correction converter, has a switching device that is actuated in accordance with a duty cycle. A duty cycle adjuster is responsive to detection of the drop in the input voltage to adjust the duty cycle of the switching device in order to limit an input current surge through the switching device below a desired level after the input voltage returns.

    摘要: A single spring supporting device includes a connecting seat, a fixing seat, and a fixing mechanism. The connecting seat and the fixing seat are respectively connected to two sides of the fixing mechanism. The connecting seat is for connecting a display, while the fixing seat is for fixing the supporting device to a position. The fixing mechanism further has a holder, in which a blocking plate and a fixing rod are arranged. One side of the fixing rod is arranged through the blocking plate. An elastic element, in addition, is arranged through the fixing rod, another side of which is rotationally connected to a nut. The display is adjusted to an optimally viewing angle by in cooperation with the blocking plate to control a telescoping operation of the elastic element and by adjusting the relative angles of the fixing mechanism with respect to the connecting seat and the fixing seat.

    摘要: A method for identifying a layer number of an optical disc is provided. Firstly, a SA value is adjusted to a standard SA value of each of two data layers in sequence. Next, focusing courses are performed so as to enable the focus point to pass through the optical disc. Then, maximum amplitudes of focusing error signals in the focusing courses are recorded. After that, whether the maximum amplitudes of the focusing error signals recorded in the focusing courses are equal is checked. If the maximum amplitudes are equal, the optical disc is identified as a double-layered disc. If the maximum amplitudes are not equal, the optical disc is identified as a single-layered disc.
