  • Publication number: 20090172437
    Abstract: A power switch includes a power status providing module, a trigger, and a logic circuit. The power status providing module is configured for providing a first signal when being turned on, and for providing a second signal when being turned off. The trigger is configured for providing a first logic voltage when being pushed down, and for providing a second logic voltage when being released. The logic circuit has a data input terminal, a clock input terminal and an output terminal. The data input terminal is configured for receiving the first signal and the second signal to form a data signal. The clock input terminal is configured for receiving the first logic voltage and the second logic voltage to form an operation clock. The output terminal is configured for outputting a power control signal inverse to the data signal according to the operation clock.

  • Publication number: 20080235896
    Abstract: A wiper blade structure comprises a pivot assembly, a plurality of deflectors, a plurality of end ferrule caps, a resilient strip, and a blade element. The pivot assembly may comprise a connecting adapter for engaging various wiper arms and the connecting adapter is further coupled with a pivot socket settled on the resilient strip, so that the connecting adapter can be easily connected with various wiper arms. Besides, by the combining structure among the pivot socket, end ferrule caps and the resilient strip, as well as the combination among the deflectors, resilient strip and the blade element, the wiper blade can firmly and closely contact the windshield glass, so that the defects of the conventional wiper blade structures can be remedied. Thus, the disclosed subject matter can perform improved efficiency of use and therefore is an invention having utilitarian value.

  • Publication number: 20070229448
    Abstract: A backlight module including a control unit, a backlight driving unit, a first light source set, and a second light source set is provided. The backlight driving unit is controlled by the control unit to generate a driving command to light on/off the light source sets. Therefore, the first and second light source set can be lighted on or off by turns according to a predetermined value, e.g., a time interval, times of power on operations. Otherwise, the second light source set may be used to compensate a brightness loss of the first light sources set when the displaying brightness is not enough, so as to maintain the displaying brightness within a predetermined range. Therefore, a longer lifetime of the backlight module can be obtained.

  • Patent number: 7056372
    Abstract: An air treatment device includes a housing, a filter element disposed in the housing, an air forcing device for forcing air to flow through the filter element, and a light device disposed in front of the filter element for generating light and for germ killing purposes. The housing includes a pressurized compartment formed between the filter element and the air forcing device, to receive the light device. An ozone generator may supply ozone through the filter element for germ killing purposes. An oxygen generator may supply oxygen out of the housing and into the environment of the users. A filter member may be used for filtering purposes, and a tray disposed below the filter member to collected filtered materials.
