  • Patent number: 10897832
    Abstract: A fan control system includes a fan and a target device. The fan control system includes a controller to control the rotation speed of the fan. The controller controls the rotation speed according to a time-variable rate of current consumed by the target device. Particularly, when the time-variable rate of current exceeds a threshold, the controller controls the fan to operate at a maximum rotation speed.

  • Patent number: 9343958
    Abstract: Various embodiments provide voltage regulator circuitry and devices. An exemplary voltage regulator circuitry can include a current comparing unit configured to convert an output voltage from a charge pump to a current and to compare the current with at least two different reference currents to generate a comparison result. A logic controller can be configured to generate a clock frequency adjustment signal based on the comparison result. A programmable clock unit can be configured to adjust a frequency of a clock signal according to the clock frequency adjustment signal to send the clock signal to the charge pump. Accordingly, the disclosed voltage regulator device can have reduced power consumption and improved reliability.

  • Publication number: 20080273643
    Abstract: A transmitter comprising: a digital encoder for encoding incoming digital information; and a digital to analog converter for converting the encoded digital information into analog information is described. The transmitter further comprises an exact time framing block disposed between the digital encoder and the digital to analog converter. The exact time framing block receives the digitally encoded information and comprises a method for synchronization. The method including the steps of: providing a clock signal having at least two adjacent pulses; providing information subjected to transmission in the form of a set of frames; and accommodating a whole number of frames between the two adjacent pulses.
