  • Patent number: 8068298
    Abstract: Harmonic selection for track following is described for a hard disk drive comprising at least one magnetic disk capable of storing data and spinning, a controller capable of controlling a read/write head capable of reading and writing data while following a track on a surface of the at least one magnetic disk, and a memory device capable of storing data relating to the operation of the hard disk drive. A drive function test on the hard disk drive is performed, during which harmonic frequencies are identified which cause disturbances for the hard disk drive. Data regarding the harmonic frequencies which cause the greatest disturbances for the hard disk drive is stored in the memory device. The data regarding the harmonic frequencies which cause the greatest disturbances is forwarded to the controller upon the at least one magnetic disk spinning.

  • Publication number: 20110289223
    Abstract: The present invention provides with a method of distinguishing a plurality of calling UEs sharing a PUID in a calling S-CSCF of IMS network and the device thereof. When a calling UE using a shared PUID in the calling-party network requests to establish a session with some called UE in the called-party network, the calling S-CSCF adds a extension identification corresponding to the calling UE into the session request message from the calling UE and sends the session request message with the extension identification added therein to the called UE in the called-party network, such that the called UE may realize which one is the actual calling UE according to the extension identification in the session request message and the shared PUID used by the calling UE. Therefore, after completion of such session, the called UE may re-establish a session with the calling UE according to the extension identification of the calling UE and the shared PUID thereof.

  • Patent number: 7617374
    Abstract: A hard disk testing method under an extensible firmware interface (EFI) is provided, which includes the following steps. A system file is backed up from the EFI of the hard disk into a storage area of a memory. The backup area of the system file is mapped as a real hard disk. A non-system file storage area is established in the memory, so as to store the non-system files of a hard disk test. Information of the system and non-system files of the hard disk test is acquired, so as to generate a system and a non-system file link table. When performing the test, the non-system files are backed up into the non-system file storage area. The system file link table and/or the non-system file link table is accessed, so as to load the system file and/or the non-system files directly from the storage area of the memory.

  • Patent number: 7579003
    Abstract: The present invention provides a combined vaccine that includes hepatitis B vaccine (HeVac) and Bacille Calmette-Guerin (BCG) for intracutaneous injection and the method of preparation of such vaccine. The combined vaccine changes the now used liquid agent of the HeVac into a cryoprotectant, thus improving the heat stability of the HBsAg. Because of the cryoprotectant in the combined vaccine, the heat stability of the HBsAg is improved, and the efficacy of the vaccine is only slightly decreased after 30 days at 37° C., and the decrease is lower than with the liquid agent of the HeVac. The present invention changes the newborn's inoculation from two injections into one to simultaneously obtain prophylaxis of hepatitis B and tuberculosis.
