  • Publication number: 20150293840
    Abstract: A memory controller is arranged for controlling the process of writing a page data to a memory, wherein the page data possesses a logical address. The memory controller includes a page buffer, a data pattern detector and a logical-physical address mapping table. The page buffer is used for buffering the page data. The data pattern detector is coupled to the page buffer, and used to detect whether the page data is a predetermined pattern, to generate a data pattern flag, and determine whether to write the page data to a physical address of the memory according to the data pattern flag. The logical-physical address mapping table is coupled to the data pattern detector, and is arranged for storing the data pattern flag and the logical address of the page data, and selectively generating and storing the physical address.

  • Publication number: 20150153901
    Abstract: A scan method for a capacitive touch panel has steps of performing a relatively small first number of estimation scans on multiple sensing lines of a capacitive touch panel and recording results of the estimation scans, marking the sensing lines meeting a predetermined condition according to the results of the estimation scans, and performing a relatively large second number of practical scans on the marked sensing lines. Given the first-stage estimation scans and the second-stage practical scans, the sensing lines possibly touched by a touch object can be rapidly identified and marked, and the second-stage practical scans are performed on the marked sensing lines. Accordingly, noises and errors can be effectively reduced, accurate scan can be ensured, and higher frame rate can be achieved.

  • Patent number: 8667475
    Abstract: A program-converting module for a multi-axis cooperated machine and a program-converting method. Machining programs and mechanism data of a plurality of first machines are input to a first input module. Mechanism data of a plurality of second machines are input to a second input unit. A setting unit sets at least one of the first machines to be a source machine, and sets one of the second machines to be a target machine. A conversion unit uses a kinematical method to convert the machining program of the source machine into a machining program applicable to the target machine based on the mechanism data of the source and target machines, without requiring CAD/CAM software.

  • Patent number: 6792602
    Abstract: The invention provides a solution/device for controlling external parameters by use of the same data cable and specific software to transfer/receive messages and monitor/control external parameters in a system. Additionally, the invention is compatible with ATA/ATAPI by using the ATA protocol or side-band protocol to make a main system communicate with other device(s) through an ATA/ATAPI device's data cable. Also, the invention uses the system's data cables and a non-standard controlling sequence to transfer and receive messages by the same cable to connect with the external devices for monitoring/controlling external parameters. Hence, the number of data wires needed is reduced. Also, the invention can decrease the manufacture costs and get a better heating dissipation.
