Abstract: A method for selecting a base station is applied to a mobile station. The mobile station sets a preset distance corresponding to a datum base station. The method comprises selecting a first base station to be a serving base station; and obtaining a first C2 parameter of a second base station corresponding to the mobile station, and obtaining a second C2 parameter as a base for the mobile station in selecting the serving base station when a distance between the second base station and the datum base station is determined to be smaller than the preset distance, wherein the second C2 parameter is equal to the first C2 parameter plus a threshold value.

Abstract: A wet etching method for making calibration bump disks for use in providing quality control of production run magnetic hard disks is disclosed. It includes the steps of: (a) coating a layer of bump material on a substrate; (b) coating a photoresist layer on the layer of bump material; (c) exposing the photoresist layer to a light source under a photomask; (d) developing the photoresist layer using a developer solution to form an undeveloped photoresist layer; (e) etching the substrate containing the layer of bump material and the undeveloped photoresist layer to remove portions of the layer of bump material not covered by the undeveloped photoresist layer; and (f) stripping the undeveloped photoresist layer to leave at least a bump on the substrate which was originally covered by the undeveloped photoresist layer. The wet etching method eliminates many of the problems observed from the conventional metal mask method, including the elimination of the convex-shaped bump surface.

Abstract: An injection-locked frequency divider is provided and which includes an injection transistor, an oscillator, a current source and a transformer. The injection transistor is used to receive an injection signal. The oscillator is used to divide the injection signal to generate a divided frequency signal. The current source is coupled to the oscillator to provide a current to the oscillator. The transformer is coupled between the injection transistor and the oscillator to increase the equivalent transconductance of the injection transistor, and thus increasing the locking range of the injection-locked frequency divider.

Abstract: In a method for inspecting the layout of a printed circuit board (PCB), a component to be checked is determined from an electronic layout diagram of the PCB, and a power transmission line which may be serving that component is selected. The layout diagram is checked to determine whether the component is connected to the power transmission line, and further checked to determine whether more than one ground pins of the component is connected to the power transmission line. Vias that are shared by two or more ground pins of the component are determined if more than one ground pin is connected to the power transmission line. Shared vias are marked on the layout diagram.
