  • Patent number: 10327096
    Abstract: The present invention relates to improvements to systems and methods for determining a current location of a client device, and for identifying and selecting appropriate geo-fences based on the current location of the client device. An improved geo-fence selection system performs operations that include associating media content with a geo-fence that encompasses a portion of a geographic region, sampling location data from a client device, defining a boundary based on the sampled location data from the client device, detecting an overlap between the boundary and the geo-fence, retrieving the media content associated with the geo-fence, and loading the media content at a memory location of the client device, in response to detecting the overlap.

  • Publication number: 20100132419
    Abstract: A method for operating a locking device, wherein the locking device disposed in a first main body includes a first locking element. In an embodiment, when the first locking element is forced to separated from a second locking element disposed on a second main body, a pushing element connecting the second main body through an elastic element receives an elastic force by the elastic element to push the second locking element, so that the second main body moves with respect to the first main body. In another embodiment, when a first force is applied onto the first locking element so that the first locking element exits the locking position of the first locking element and the second locking element, a damping restoration element pivoted between the first locking element and the first main body drives the first locking element to be resumed to the locking position after a time interval.

    Abstract: The invention is directed to a nitridation process for a wafer. The nitridation process comprises steps of disposing the wafer on a top surface of a chuck in a nitridation process tool, wherein a plurality of concentric pipe coils is disposed close to the bottom surface of the chuck. Then, the chuck is heated and the chuck is regionally cooling down by applying a coolant into the concentric pipe coils, wherein the flow rates of the coolant in the concentric pipe coils are different from each other. Furthermore, a plasma nitridation process is performed on the wafer.

  • Publication number: 20060072274
    Abstract: A method of controlling surge current in fan modules is applied in a blade server. The blade server includes a fan module having a first fan motor, a second fan motor, a first resistor/capacitor (RC) circuit and a second RC circuit. The blade server generates a control signal for controlling the first and the second fan motors. The first RC circuit receives and delays the control signal for a period of first time to output a first delay control signal for driving the first fan motor. The second RC circuit receives and delays the control signal for a period of second time to output a second delay control signal for driving the second fan motor. The first time is different from the second time and thus the first surge current in the first fan motor and the second surge current in the second fan motor are generated at different time.
