    摘要: The present invention provides a system and method for fail-safe call survival by detecting failure of an active call serving component and switching the service over to a standby component. The system and method will prevent an existing call, whether established or to be established, from being dropped due to a single point of failure within a Voice over Internet Protocol system. The continuation of the call is based on the failed component as opposed to relying on communication endpoints to re-initiate or re-route the failed call. Call recovery is initiated independent from the call path of a call. The detection of a condition or need for call recovery and the determination to initiate call recovery procedures are made without involving endpoints or intermediate points of the call. The availability and sanity of all components are continuously monitored and are tailored specifically for the duties of each component.

    摘要: A novel method for the preparation of a compound of formula (I) from an N—protected-D-mannosamine. A compound of formula (I) is a useful intermediate for the preparation of kiftnensine, a potent and selective mannosidase inhibitor. The method includes protecting the hydroxyl group at the C-6 position of an N—protected-D-mannosamine, to give a 6—O—protected—N—protected-D-mannosamine; reducing the C-1 anomeric carbon atom of the 6—O—protected—N—protected-D-mannosamine to give a 6—O—protected—N—protected-D-mannitol; protecting the four hydroxyl groups of the 6—O—protected—N—protected-D-mannitol; and removing the nitrogen atom protecting group and optionally removing the C-6 oxygen atom protecting group to give the compound of formula (I): where R1 and R2 are each independently protecting groups which, together with the oxygen atoms to which they are attached, form a 5-, 6-, 7- or 8-membered ring; and R3 is hydrogen or a protecting group.

    摘要: A computing device has encrypted content and a corresponding license having a decryption key for decrypting the content. The license allows the computing device to render the content thereon. The computing device may issue a sub-license based on the license to a portable device. The sub-license allows the portable device to render the content thereon and has the decryption key. The portable device has a digital device certificate including information thereon. The computing device receives from the portable device the device certificate thereof, and determines based on rules in the license and the information on the portable device in the device certificate whether the computing device can issue the sub-license to the portable device. If so, the computing device constructs such sub-license to include the decryption key (KD) and transmits the constructed sub-license to the portable device.

    摘要: A method is provided for a computing device to copy (burn) a playlist of tracks to a portable medium, where each track corresponds to a piece of digital content. At least one of the pieces of content is rights-management (RM) protected and accordingly is burned to the portable medium only in accordance with a corresponding digital license.
