  • Patent number: 7852649
    Abstract: In a feedback circuit of a power supply, an electrical level of an output voltage is stabilized corresponding to changes of an electrical level of a pulse width modulation signal, and effects, which are caused by spikes, on passive elements are decreased to a lowest degree. The electrical level of the output voltage is stabilized by storing a voltage corresponding to a low-to-high electrical level of the PWM signal with a capacitor, by discharging the stored voltage with a high-to-low electrical level of said PWM signal, and by regulating a discharging path of the stored voltage with a diode, which is not conducted. The abovementioned disposition may be utilized on various power-consuming devices, a duty cycle of each of which is controlled with a PWM signal, for stabilizing output voltages of said power-consuming devices, and for reducing effects, which are caused by spikes, on passive elements inside said power-consuming devices.

    Abstract: An anti-aliasing process without sorting the polygons in depth order to improve the image quality in three-dimensional graphics system. This method comprises extra buffer memory than does a typical three-dimensional graphics display system. The Z buffer stores the depth value of nearest pixel in front Z buffer and depth value of secondary nearest pixels in back Z buffer. The color buffer stores foreground color and background color. A weighting value is used and stored in the frame buffer to blend the foreground color and the background nearest color. The weighting value is associated with each pixel, it indicates the percentage of coverage of a pixel. Every pixel in Z buffer test stage will update the depth of the nearest pixel and the depth of the second nearest in Z-buffer, foreground color and background color in the frame buffer and the weighting value according to the result of depth comparison.
