Abstract: An apparatus to eliminate the power-off image noise of a flat panel display has a reset circuit and a switching device. The reset circuit asserts a switch signal when the flat panel display is turned off. The switching device decouples a source driver from several latch signals generated by a timing controller when the switch signal is asserted.

Abstract: A heat dissipating system provides a fast heat dissipating airflow stream inside a desktop computer and thereby greatly enhances the heat dissipating efficiency of the desktop computer. The computer heat dissipating system includes a computer chassis which has a circular opening bored on its front plate, a motherboard which has a thermal module including a front cooling fan and a set of chipsets heatsink module installed on its top surface, and a power supply with a cooling fan. The thermal module, the chipsets heatsink module, and the power supply are aligned along a single heat dissipating airflow stream. The external low temperature air first passes through the thermal module and removes the heat generated by the central processing unit, further flows into the chipsets heatsink module and removes the heat generated by the MCH chipsets and ICH chipsets, and finally enters into the power supply and removes the heat generated by the power supply.

Abstract: An apparatus for adjusting brightness of indicator light on a panel is provided. By employing pulse width modulated signals, one can control the amount of current flowing into the indicator light, thereby adjusting the brightness of the indicator light. The apparatus includes a control unit, which generates pulse width modulated signals in response to a user defined condition, and a switch element, which is coupled between the output end of the indicator light and the resistor for receiving the pulse width modulated signals, thereby controlling the amount of current flowing into the input end of the indicator light. One can thus obtain optimized indicating effects and visual comforts.
