  • Patent number: 6943784
    Abstract: A control circuit of panel brightness is disclosed. After a user adjusts a brightness volume control, the brightness volume control will output an adjusting signal. The control circuit of this invention includes a pre-stage circuit, a first brightness control circuit, and a second brightness control circuit. The pre-stage circuit is fro receiving a darkness-adjusting signal, a brightness-adjusting signal, and an enable signal. A first brightness value outputted from the first brightness control circuit can be the first brightness value of the previous time point plus or minus a interval. A second brightness value outputted from the second brightness control circuit can be the second brightness value of the previous time point plus or minus a interval. The first brightness value and the second brightness value are for adjusting panel brightness. The circuit of this invention is simple, easy to design, and less cost.

  • Patent number: 6904533
    Abstract: An apparatus of delivering the power status data signal of the smart battery includes a control device, a data buffer device and a data storage device. The control device is for outputting a smart battery clock signal, a first clock signal and a second clock signal according to an input clock signal, and for receiving and outputting the power status data signal serially. The data buffer device is for receiving the power status data signal serially and outputting the power status data signal in parallel according to the first clock signal. The data storage device is for storing the power status data signal and outputting the power status data signal in parallel according to the second clock signal.

  • Patent number: 6859150
    Abstract: A new apparatus for reading keyboard-commands of a portable computer comprises a shift register, a keyboard-matrix circuit, a filter, a buffer, an address generator, a mapping device, a comparator, and an output device. The shift register is for outputting a plurality of scan-input signals and a reference signal. The keyboard-matrix circuit is for outputting a scan-output signal according to the scan-input signals. The keyboard-matrix circuit includes a plurality of nodes corresponded to the keyboard buttons, respectively. The filter is for filtering the noise of the scan-output signal. The buffer is for further stabilizing the filter signal. The address generator is for reading the location of the node corresponding to the button being pressed. The mapping device is for outputting a mapping signal corresponding to the button being pressed. The comparator is for outputting a comparing signal, which represents the command corresponded to the pressed button.
