  • Publication number: 20080291704
    Abstract: In a driving device and method for providing an AC driving signal to a load, a first voltage converting unit converts an external AC voltage signal into a DC voltage signal using pulse width modulation in response to a feedback signal that is generated by a summing unit based on a standard voltage signal generated by a voltage detecting unit from the DC voltage signal, and a current detecting signal corresponding to a current flowing through the load and generated by a current detecting unit. A second voltage converting unit converts the DC voltage signal from the first voltage converting unit into the AC driving signal based on an external burst signal, and outputs the AC driving signal to the load.

  • Patent number: 6875041
    Abstract: An ejecting apparatus for ejecting a data card and releasing a first object from an electrical device. The ejecting apparatus includes a latch movably connected to the ejecting apparatus. The latch contains a retaining member adapted for insertion into a corresponding groove on the first object for engaging with the first object, and a releasing knob monolithically formed with the retaining member, and adapted to move the latch with respect to the ejecting apparatus for releasing the retaining member from the groove of the first object and enabling the first object to be removed from the electrical device. The ejecting apparatus also includes a pivoting shaft for pivotally connecting the ejecting apparatus to the electrical device, and at least one ejector leg for pushing the data card from the electrical device to eject the data card as the ejecting apparatus is rotated from the electrical device about the pivoting shaft.
