  • 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.

  • Sideward clipping apparatus
    Publication number: 20070081855
    Abstract: A sideward clipping apparatus aims to clip and release an article through double-depressing actions in cyclic operations. It has a sliding member which includes an upper clipping portion and a lower clipping portion that are coupled through a first base and a second base. The lower clipping portion synchronously drives the upper clipping portion through the first base at an initial force receiving state to form a first fan moving track. The lower clipping portion is in contact with the sliding member and moved vertically to a second position under the force to drive the upper clipping portion through the second base to form a second fan moving track. Thereby the upper clipping portion and the lower clipping portion form a clipping space when the sliding member is moved to the second position to accurately clip the article.
