  • Publication number: 20120014997
    Abstract: Compounds are provided that act as potent antagonists of the CCR9 receptor, and which have been further confirmed in animal testing for inflammation, one of the hallmark disease states for CCR9. The compounds are generally aryl sulfonamide derivatives and are useful in pharmaceutical compositions, methods for the treatment of CCR9-mediated diseases, and as controls in assays for the identification of CCR9 antagonists.

  • Publication number: 20110299624
    Abstract: The present invention provides a device and method for realizing prefix code construction. The device includes a sort indexer, a generator and a sequence regulator. The sort indexer is used to sort a group of received code lengths to obtain a group of sorted code lengths, and record the position correspondence relationship. The generator receives the sorted code lengths and orderly generates the prefix codes. Except that the first prefix code is preconfigured, the generator generates a current prefix code by adding one to the adjacently previous prefix code and then shifting left by a certain number of bits. When the current prefix code is generated, the generator simultaneously judges whether the adjacently previous prefix code is identical to the current prefix code from the high bit, if yes, the error information is outputted; otherwise the prefix codes corresponding to the sorted code lengths are generated.

  • Publication number: 20110181531
    Abstract: An electronic paper device is provided. The electronic paper device includes a touch panel, a conductive layer, a plurality of pixel electrodes, an electrophoretic ink layer, a common electrode layer, and a processing unit. The electrophoresis layer is electrically connected between the plurality of pixel electrodes and the common electrode layer. The conductive layer and the common electrode layer respectively have a different voltage. When the user touches the electronic paper device, causes the touch panel produce a touch signal and the conductive layer contacts a pixel electrode corresponding to the touch position. Then the processing unit determines the touch position according to the touch signal. The pixel electrode obtains the voltage of the conductive layer and an electric field is form between the pixel electrode and the common electrode layer. This causes the color to change at the position that is corresponding to the touched position.

  • Publication number: 20110181576
    Abstract: An electronic paper device is provided. The electronic paper device includes a conductive layer, a number of pixel electrodes, an electrophoretic ink layer, a common electrode layer, a voltage detection unit, and a processing unit. Each pixel electrode corresponds to a coordinate of a coordinate system. The electrophoretic ink layer is electrically connected between the number of pixel electrodes and the common electrode layer. The conductive layer and the common electrode layer have a different voltage when the electronic paper device is powered on. When the user touches the electronic paper device and causes the conductive layers to contact a pixel electrode corresponding to the touch position, the pixel electrode obtains the voltage of the conductive layer and an electric field is form between the pixel electrode and the common electrode layer. This causes the color to change at the position that is corresponding to the touched position.

  • Publication number: 20100145477
    Abstract: Method and apparatus for command synchronization is described. In some embodiments, a remote system system may set up a user interactive session with a local device according to a user interaction protocol. The remote system may insert a predetermined execution time into a first command and send the first command to a local device according to the user interaction protocol. The first command, when executed on the local device, causes a second command compliant with the user interaction protocol to execute on the local device at the predetermined execution time.
