  • Patent number: 8531129
    Abstract: A passive current balance driving apparatus has a circuit topology composed by several simple passive components and is capable of driving a plurality of LED strings simultaneously. The present passive current balance driving apparatus is mainly configured such that each LED string has the identical load characteristics during the positive and negative half cycles of the AC power. As such, the currents flowing through the respective LED strings are basically/substantially equal, thereby achieving the current balance.

  • Patent number: 8462198
    Abstract: The animation generation system includes: an avatar generation module for generating an avatar in a virtual space, wherein the avatar has a set of skeletons and a skin, and the movable nodes of the set of skeletons are manipulated so that a motion of the skin is induced; and an avatar manipulation module for manipulating the movable nodes, including: a position mark which is moved to at least one first real position in a real space; at least one control mark which is moved to at least one second real position in the real space; and a video capturing unit for capturing the images of the real space; an arithmetic unit for identifying the first real position and the second real position from the images of the real space, and converting the first real position into a first virtual position, and the second real position into a second virtual position.

  • Patent number: 7477025
    Abstract: The present invention discloses a power control circuit for adjusting light, which adopts both frequency modulation and amplitude modulation for the control and starts using the amplitude modulation control after the frequency change exceeds a predetermined limit range, such that the voltage and frequency for driving the lamp set fall within a range acceptable to the lamp set and minimize the effect of frequency interferences.

  • Publication number: 20080165554
    Abstract: A control method of a power converter for modulating a power signal outputted from a power converter to a load according to a feedback signal of the load includes the steps of: receiving a reference signal to determine outputting a modulation signal; receiving the modulation signal to determine outputting an electric conduction signal based on the working condition of a transformer unit in the power converter; receiving the electric conduction signal to determine outputting an oscillation signal of the transformer unit; modulating the duty cycle and frequency of the modulation signal simultaneously according to a feedback signal, if said feedback signal is inputted; receiving the modulation signal to change a power operating time interval for outputting the electric conduction signal; and receiving the electric conduction signal after the power operating time interval is changed to determine outputting the oscillation signal of the transformer unit.
