  • Publication number: 20070061203
    Abstract: Methods and systems for dynamically incorporating advertising content into multimedia environments, such as games, are provided. Example embodiments include a dynamic inserter, which selects content, based upon a set of criteria, to deliver to a receiving client system, such as a game client. The receiving client system typically dynamically determines locations within the game where advertisements are desirably inserted. Associated with these locations are ad tags that specify criteria for the ads including, for example ad type, ad genre, and scheduling information which are sent by the client system to the dynamic inserter to select appropriate ads. The dynamic inserter selects ads based upon the criteria and sends them to the client system, which selects them for ad tags with conforming criteria. The client system then renders the selected ad in the appropriate location.

  • Publication number: 20070043680
    Abstract: A digital license is migrated from a source platform to a target platform. At the source platform, a migration image is produced to include the license and corresponding data therein, and the license is deleted from such source platform. At the target platform, permission is requested from a centralized migration service to migrate the license in the migration image to the target platform. The migration service determines whether to permit migration of the license based on predetermined migration policy. Upon receiving the requested permission as a response from the migration service, the migration image is applied to the target platform by un-tying the license from the source platform and re-tying the license to the target platform.

  • Publication number: 20060235801
    Abstract: 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.

  • Patent number: 6799121
    Abstract: A strategy for semiautomatic sequencing of argentinated (silver-containing) oligopeptides is described. The method of sequencing described is based on a search algorithm that identifies a triplet peak relationship in a product ion spectrum of the [M+Ag]+ ion of an oligopeptide. The ions that constitute a triplet are [bn+OH+Ag]+, [bn−H+Ag]+, and [an−H+Ag]+, which are separated by 18 and 28 m/z units, respectively. The difference in the m/z values of adjacent triplets identifies the residue that is “cleaved”. Observation of the [yn+H+Ag]+ ion containing the cleaved residue confirms the assignment.
