Abstract: In one aspect of the invention is a method for preventing unauthorized copies of a medium, such as a DVD, from being played by a compliant device by using the validation area (VA) region of a medium to validate keying material. A compliant device is a device that will validate keying material. In one embodiment of the invention, a compliant device validates keying material by using the value in the VA region of the medium. In alternative embodiments, a compliant device will validate keying material by checking correspondence between keying material written to a non-VA region of a medium and validation data written to a VA region of a medium. In the alternative embodiments, if the keying material does not correspond to the validation data, then a compliant device will prevent the contents of the medium from being played.

Abstract: A network storage system includes a virtual file system (“VFS”) that manages the files of the network storage system, and a storage center that stores the files. The VFS and the storage center are separated, such that a client accesses the VFS to conduct file system operations and the client accesses the storage center to upload/download files. The client accesses the network storage system through one or more storage ports. The storage center includes a plurality of distributed object storage managers (DOSMS) and a storage cluster that includes a plurality of intelligent storage nodes. The network storage system includes additional storage centers at geographically disparate locations. The network storage system uses a multi-cast protocol to maintain file information at the DOSMs regarding files stored in the intelligent storage nodes, including files stored in disparate storage centers.

Abstract: An integrated radiating enclosure is disclosed. The enclosure housing is formed from a dielectric material with a radiating element formed on the exterior surface of the housing and a groundplane material formed on the interior of the housing. The groundplane provides EMI shielding for the enclosed electronics. The three antenna elements are directly connected to the circuitry of a transceiver system, thereby integrating the transceiver antenna components directly into the transceiver enclosure.

Abstract: A network driver for transmitting packets. For a particular embodiment the driver receives an indication that a packet is available for transmission and monitors a packet pending transmission status of a network controller. The driver then indicates to the network controller that the packet is available for transmission only when the pending transmission status in one particular embodiment reaches a threshold value. Thus the driver determines how many packets to provide a network controller based on the amount of packets still waiting to be transmitted by the controller.

Abstract: A method and apparatus are described for providing an implicit write-back in a distributed shared memory environment implementing a snoop based architecture. A requesting node submits a single read request to a snoop based architecture controller switch. The switch recognizes that another node other than the requesting node and the home node for the desired data has a copy of the data. The switch directs the request to the responding node that is not the home node. The responding node, having modified the data, provides a single response back to the switch that causes the switch to both update the data at the home node and answer the requesting node. The updating of the data at the home node is done without receiving an explicit write instruction from the requesting node.

Abstract: A capacitive signal coupling device to link an antenna radiating element to a peripheral device is disclosed. The capacitive signal coupling device includes a support and at least one conductive element on a first surface of the support.

Abstract: Methods and apparatus for accessing service agents on non-subnet manager hosts in an Infiniband subnet. A service agent at a first host registers with a first General Service Agent (GSA) at the first host. The registration is sent to a second GSA at a second host if the first host is not a subnet manager. The second host is a subnet manager. The second host sends a request for access/identification information to the service agent. The requested access/identification information is received at the second host. A service request is received at the second host for the service agent at the first host. The service request is from a client on the Infiniband subnet. The client is redirected to the first host by the second host sending the client a message. The service request for the service agent is sent to the first host by the client. The first host, second host, and client are part of an Infiniband subnet.

Abstract: A method, apparatus, and system are described for processing an operation code (op-code) to be transmitted over a data path of a graphics pipeline. If the op-code comprises context state information for a first graphics context, then the context state information is transmitted to registers in the graphics pipeline over the graphics pipeline data path. If the op-code comprises a save state command, then context state information in the registers is retrieved and transmitted from the registers to a preallocated region of a frame buffer over the same graphics pipeline data path. If the op-code comprises a restore/load state command, then new context state information is loaded. Context state information for a second context can then be loaded on the graphics pipeline data path to restore or process a new context.
