  • Publication number: 20100053080
    Abstract: A method for setting up location information on display screens and a recognition structure thereof includes an encoding unit and an image generation unit to output respectively at least one location information and a plurality of image information in a unit of time, and a synthesizing unit to integrate the location information and the image information to become synthesized information transmitted to a display unit to be output. The invention further has an image capturing unit to capture local information of the synthesized information from any location of the display unit. The local information is sent to a recognition unit to be recognized. The recognition unit outputs a recognition signal to the image generation unit which in turns outputs the image information of a location on the display unit pointed by the image capturing unit. This invention can accomplish effects same as the touch screen.

  • Publication number: 20060009237
    Abstract: A partitioning method for a mobile communication network with overlapping location areas is disclosed. The method comprises: finding at least a potential LAC labeling operation for each cell within the network; determining a respective gain for each potential LAC labeling operation; selecting one potential LAC labeling operations according to the respective gains; and adjusting the LAC list of the cell according to the selected operation. The method can provide an optimal partitioning to upgrade the network performance.

  • Publication number: 20060009207
    Abstract: A partitioning method for a mobile communication network with an initial partition plan is disclosed. The partitioning method comprises: performing at least one of a plurality of network partitioning algorithms to generate a following partition plan; generating a corresponding function value for each of the initial and following partition plans according to an objective function; and selecting a better one of the initial and following partition plans according to the corresponding function values. The partitioning method can generate a refined or optimized partition plan in a systematic way to reduce the network load.
