  • Patent number: 11940737
    Abstract: A method includes receiving a device design layout and a scribe line design layout surrounding the device design layout. The device design layout and the scribe line design layout are rotated in different directions. An optical proximity correction (OPC) process is performed on the rotated device design layout and the rotated scribe line design layout. A reticle includes the device design layout and the scribe line design layout is formed after performing the OPC process.

  • Patent number: 8441205
    Abstract: A dimming apparatus transmitting control signals with AC power line (10) is applied to an alternating current power source (20), a light emitting diode driving power unit (40), and a light emitting diode unit (30). The dimming apparatus transmitting control signals with AC power line (10) includes an input voltage detection unit (102), a one-shot signal unit (104), an AND gate unit (106), a pulse width modulation dimming signal unit (108), an inductor unit (110), a first switch unit (114), a dimming signal recovery unit (124), and a second switch unit (122). The input voltage detection unit (102) is electrically connected to the alternating current power source (20), the inductor unit (110), and the one-shot signal unit (104). The AND gate unit (106) is electrically connected to the one-shot signal unit (104), the pulse width modulation dimming signal unit (108), and the first switch unit (114).

  • Publication number: 20120293903
    Abstract: A power supply apparatus with an inrush current prevention circuit is applied to a parallel power bus. The power supply apparatus includes a filter capacitor and a current control unit. The current control unit is electrically connected to the filter capacitor. The current control unit controls a charged current flowing through the filter capacitor to prevent an inrush current generated in the parallel power bus.

  • Publication number: 20040239401
    Abstract: A zero-voltage-switching full bridge converter has first and second switching units between which a transformer is coupled. Each switching unit is composed of two MOSFETs as the switching elements and controlled by a non-overlap gate driver. For either the first switching unit or the second switching unit, the activated periods of the driving signals for the two switching elements do not overlap. Therefore, the switching loss of the full bridge converter is mitigated.
