  • Patent number: 8432857
    Abstract: A wireless access device communicates with a plurality of customer premised equipments (CPEs) via a network. The wireless access device establishes a plurality of queues and distributes intervals for each of the CPEs. The wireless access device receives packets from the network, obtains one of the intervals corresponding to one of the CPEs with a MAC address being a destination MAC address of one of the received packets, and stores each of the received packets to one of the queues with sequence number being in the obtained interval. The wireless access device transmits the received packets stored in the plurality of queues in the way of one row by one row.

  • Patent number: 8423552
    Abstract: A method for calculating connectivity of a space having a number of objects using a computer system includes establishing a character matrix having a number of elements in accordance with the objects. A label matrix is established, and the character matrix is divided into blocks. Connectivity of the elements of each of the blocks is calculated, and then the elements are grouped into regions based on the values of the elements. Each of the regions is labeled and enhanced. Connectivity of the regions is calculated, and the regions are grouped into larger regions based on the values of the elements.

  • Patent number: 8375398
    Abstract: An electronic system comprises a memory, a parser, and a device driver. A plurality of applications and a document are stored in a user space of the memory, the document storing configuration parameters. The parser module parses the document to retrieve the parameters in response to invocation from at least one application. The device driver creates data structure for the parameters in the kernel space of the memory, thus to facilitate a plurality of programs to execute different functions of the system by commonly utilizing the parameters through the device driver.

  • Patent number: 8345985
    Abstract: In an electronic device and method of matching an image A and an image B, grayscale centers of the image A and the image B are computed. The image A is divided into n equal parts Dk(k=1˜n) according to the grayscale center, and a grayscale density Vk of each part Dk is computed, to acquire n grayscale densities Vk(k=1˜n) which are regarded as feature data u of the image A. Feature data v of the image B is extracted in the similar way. A similarity of a grayscale density Vak selected from the feature data u and the grayscale density Vbk selected from the feature data V, is computed. Thus, n similarities are computed. A similarity ?(n, u, v) of the image A and the image B is computed according to the n similarities.

  • Publication number: 20120326839
    Abstract: An electronic device creates a table for mapping a plurality of pressure values corresponding to a plurality of numerical values, and stores the pressure mapping table in a memory. The electronic device detects a touch on a touch panel of the electronic device and detects a value of the pressure of the touch. The electronic device obtains a numerical value corresponding to the detected pressure value in the pressure mapping table. The electronic device generates a password code as a result of user input based on the numerical value.
