  • Patent number: 11936238
    Abstract: An uninterruptible power apparatus is coupled between a power grid and a load. The uninterruptible power apparatus includes a bypass path, a power conversion module, and a control module. The bypass path is coupled to the power grid through a grid terminal, and coupled to the load through a load terminal. The control module turns off a first thyristor and a second thyristor by injecting a second voltage into the load terminal during a forced commutation period. The control module calculates a magnetic flux offset amount based on an error amount between the second voltage and a voltage command, and provides a compensation command in response to the magnetic flux offset amount. The control module controls the DC/AC conversion circuit to provide a third voltage to the load terminal based on the compensation command and the voltage command.

  • Publication number: 20070261002
    Abstract: A portable electronic device is provided. The portable electronic device comprises a touch screen, a storage device, a pointer generator, an icon generator, and a controller. The touch screen provides a waiting screen. The storage device stores a plurality of entry functions corresponding to items arranged in a hierarchical menu, wherein each of the entry functions operates to display a respective screen on the touch screen. The pointer generator generates a pointer directing to one of the entry functions regardless of the position in the hierarchical menu of the corresponding item. The icon generator generates a shortcut icon, associated with the pointer, on the waiting screen. The controller determines whether the shortcut icon is manipulated in a predetermined way, and if so, activates the entry function corresponding to the manipulated shortcut icon.

  • Patent number: 7199729
    Abstract: A conversion method converting characters from a source character set to a destination character set. An index table, a key table, and an encoding table are provided. Source character code of a character is divided into a first part and a second part. A head offset and a tail offset are acquired in the index table according to the first part. The second part is searched in the key table based on the head offset and the tail offset. Destination character code of the character is retrieved from the encoding table matching to the searching result.

  • Publication number: 20060173901
    Abstract: Methods for merging files and related systems. A first file comprising a plurality of columns is provided. Each column comprises at least one data field for a row corresponding to a string identification. It is determined whether the string identification corresponding to the row is in a second file. If the string identification is in the second file, data for the row corresponding to the string identification in a first column of the second file is written to the row in the first column of the first file. If the string identification is not in the second file, data for the row in a second column of the first file is copied to the row in the first column of the first file.
