  • Arc discharge protection apparatus operating in current detection mode
    Publication number: 20070109706
    Abstract: An arc discharge protection apparatus operating in a current detection mode aims to prevent arc discharge caused by abnormal conditions in a high voltage output zone. The arc discharge protection apparatus has a current signal sampling unit to receive an arc discharge current signal generated in the high voltage output zone, an interpretation unit to provide a determination level to sift out an abnormal current frequency signal, a commutation unit to receive and rectify the abnormal current frequency signal and output an arc DC signal, and a touch control unit driven by the arc DC signal to output a trigger signal to stop operation of the high voltage output zone. Thereby sparking or burning caused by heat accumulation of the peripheral elements resulting from the arc discharge can be prevented.

  • Power supply to provide operation power for cooling fans
    Publication number: 20070097721
    Abstract: A power supply to provide operation power for cooling fans includes a non-stop power system to provide DC power in normal conditions to a remote switch control circuit to set a computer in an ON or OFF condition. The non-stop power system also outputs the DC power to a fan actuation control circuit to drive a rear end cooling fan. The fan actuation control circuit and the remote switch control circuit are bridged by a cooling delay unit. The cooling delay unit receives a computer ON/OFF signal from the remote switch control circuit and outputs another signal to enable the cooling fan to operate for a period of time before stopping.

  • Power driver circuit of display panel
    Patent number: 7211969
    Abstract: A power driver circuit for a display panel. The power driver circuit includes a power controller, and a resident power system, which is coupled to an alternating power source and provides resident power for the power controller. When receiving an external on/off signal, the power controller will output driving signals to initiate or close the low-voltage power converter system and the high-voltage power converter system to determine whether a low-voltage power and a high-voltage power are output to drive the display panel. Thereby, when the display panel is in an off state, only the resident power system works. Thus, the power-saving demand of environmental protection is satisfied.
