  • HEAT DISSIPATION DEVICE AND ILLUMINATION DEVICE USING SAME
    Publication number: 20100271823
    Abstract: An exemplary heat dissipation device includes an elongated main body, a number of heat sinks, and a number of airflow channels. The main body has a central axis, and includes a first portion and a second portion. The second portion has an end distant from the first portion which is configured for supporting at least one item selected from the group consisting of a solid-state light source and a circuit board having a solid-state light source mounted thereon. The heat sinks are arranged around the first portion in sequence along the central axis of the main body, and spaced from one another. Each heat sink includes a number of fins extending out from the first portion radially. The airflow channel is defined between each two neighboring heat sinks.

  • DIFFERENTIAL SIGNAL GENERATING DEVICE
    Publication number: 20100238159
    Abstract: A differential signal generating device includes a control circuit and a differential signal driver receiving a single-ended signal. The control circuit receives a source signal and generates a control signal corresponding to a first mode when the source signal conforms with a first pre-defined state, and corresponding to a second mode when the source signal conforms with a second pre-defined state. Variations of the source signal are related to signal content of the single-ended signal. The differential signal driver is coupled to the control unit for receiving the control signal therefrom. The differential signal driver outputs a differential signal output according to the single-ended signal when the control signal corresponds to the first mode. The differential signal driver outputs a non-differential signal output when the control signal corresponds to the second mode.

  • Method for adjusting parameters of equalizer
    Patent number: 7778321
    Abstract: A method for adjusting parameters of an adaptive equalizer makes use of a transmitted signal received by a receiving end to adjust parameters of an adaptive equalizer. First, signal strengths of a first frequency band and a second frequency band in the transmitted signal are detected. The signal strengths of the first frequency band and the second frequency band are then compared to get a compensation ratio, i.e., the total compensation quantity of the first frequency band to the second frequency band. Finally, the parameter setting of the equalizer is adjusted according to feedback of the compensation ratio. Optimum gain control of the adaptive equalizer can thus be accomplished to compensate signal attenuation to the transmitted signal caused by the channel.

  • DEVICE AND METHOD FOR CONTROLLING FRAME INPUT AND OUTPUT
    Publication number: 20100188574
    Abstract: A device and method for controlling frame input and output are applied to the reception of image data from a source device and output of the image data to a destination device, the device includes a buffer, a buffer control circuit, and a frame write controller. The input pixel clock is not equal to the output pixel clock. The frame write controller generates a write permission signal according to the Input DE and the Output DE. The buffer control circuit generates a write control signal according to the Input DE and the write permission signal, and generates a read control signal according to the Output DE. The buffer receives the image data from the source device according to the write control signal and the input pixel clock, and outputs the image data to the destination device according to the read control signal and the output pixel clock.

  • Hybrid phase-locked loop
    Patent number: 7679454
    Abstract: A phase-locked loop (PLL) including a digital PFD, a digital loop filter, a decision circuit, a fractional-N PLL, and a frequency divider is provided. The digital PFD generates a first detection signal according to the phase error or frequency difference between an input signal and a feedback signal. The digital loop filter generates a first control signal according to the first detection signal. The decision circuit generates a divisor value according to the first control signal. The fractional-N PLL generates an oscillation signal according to the divisor value and a reference signal. The frequency divider divides the oscillation signal to produce the feedback signal. The fractional-N PLL includes a fractional-N frequency divider for generating a frequency-divided signal for use in tracking the reference signal according to the divisor value by employing phase swallow means.
