  • Patent number: 8687476
    Abstract: A method and an optical storage medium are provided for storing data to and accessing data from an embedded virtual medium within the optical storage medium. Information describing the embedded virtual medium may be stored on to the optical storage medium. Space for an embedded lead-in area of the embedded virtual medium, as well as user data for the embedded virtual medium, may be allocated within a data zone of the optical medium. A spare sector bitmap may be included in a lead-an area of the optical medium indicating spare sectors within the embedded virtual medium as being unavailable. A spare sector bitmap may be included within the embedded virtual medium indicating available spare sectors of the embedded virtual medium. Physical sector/logical block mapping of the optical storage medium may be modified for accessing data stored on the embedded virtual medium.

  • Publication number: 20120162895
    Abstract: An electronic device enclosure configured to shield against electromagnetic interference (EMI). The electronic device enclosure includes an electronic device-enclosure base and at least one laterally disposed blunt boss. The electronic device-enclosure base includes a bottom, and sides and attached to the bottom in a boxlike configuration. The laterally disposed blunt boss is configured so as to be disposed between, and to couple electrically, a side of the electronic device-enclosure base and a vertical flange of an electronic device-enclosure cover. The electronic device-enclosure base and the electronic device-enclosure cover are configurable with respect to said laterally disposed blunt boss to shield an interior space enclosed by the electronic device-enclosure base and the electronic device-enclosure cover against EMI at a resonant frequency of a slot of the electronic device enclosure.

  • Patent number: 8114895
    Abstract: The present invention relates to an isolated bioactive molecule Caerulomycin A, derivatives and analogs thereof as effective immunosuppressive agents. The immunosuppressive property of the compound is targeted in particular against the lymphocytes, CD4+ T cells, CD8+ T cells and B cells and in the production of IL-4 and IFN-? and antibodies. The compound operates through a mechanism by downregulating the expression of activation marker CD28 and upregulating the immunosuppressive marker CTLA-4. Caerulomycin A has previously been isolated from Streptomyces caeruleus and found to have useful antifungal activity. Prior to the present invention however, this compound had not been determined to have immunomodulatory activity.

  • Patent number: 8103823
    Abstract: A method and a host processing device are provided for background formatting, or de-icing, an optical medium with no de-icing assistance from an optical drive upon which the optical medium is mounted. In a foreground mode, an optical medium may be initially formatted, volume structures may be recorded on the optical medium, file system information may be written thereto, and quick grow formatting may be performed to make the optical medium writable, at least sequentially. Under initiation and control of a file system, executing on a host processing device, the optical medium may be formatted, or de-iced, in a background mode with no assistance from an optical drive, upon which the optical medium is mounted. Under control of the file system, blocked input or output activity, may be allowed to access the optical medium upon pausing the formatting, or de-icing.
