  • Publication number: 20220320289
    Abstract: High-voltage semiconductor device and method of forming the same, the high-voltage semiconductor device includes a substrate, a gate structure, a drain, a first insulating structure and a drain doped region. The gate structure is disposed on the substrate. The drain is disposed in the substrate, at one side of the gate structure. The first insulating structure is disposed on the substrate, under the gate structure to partially overlap with the gate structure. The drain doped region is disposed in the substrate, under the drain and the first insulating structure, and the drain doped region includes a discontinuous bottom surface.

  • Publication number: 20120022925
    Abstract: A method for broadcasting advertisements is used on an electronic device. The electronic device may download the advertisements from a server of an advertiser. When the electronic device is awaked from a sleep state, the advertisements are broadcasted on a display of the electronic device. After the advertisements are broadcasted, the display then displays a window already displayed on the display before the electronic device enters the sleep state.

  • Publication number: 20100102988
    Abstract: A driving conditions monitoring device includes an image capturing unit, a data processing unit, a control unit, and an abnormality processing unit electronically connected in series. The image capturing unit includes at least two image capturing devices to respectively obtain the image of the expression of the drive and the driving road condition. The data processing unit obtains the image information form the image capturing unit, and then sends it to the control unit after processed. The control unit judges whether the states of the driver is normal or abnormal according to the image information of the expression of the drive and the driving road condition, and activates the abnormality processing unit to deal with the abnormality when the state of the driver is abnormal.
