  • Patent number: 9219446
    Abstract: A signal processing device includes a device package, processing circuitry and biasing circuitry. The processing circuitry is packaged in the device package and is operative to receive one or more Radio Frequency (RF) input signals from one or more antenna elements via one or more pre-amplifiers that are separate from the device, and to process the RF input signals so as to produce an RF output signal. The biasing circuitry is packaged in the device package and is operative to produce one or more biasing signals for biasing the pre-amplifiers.

  • Patent number: 8180747
    Abstract: Load sharing clusters in which each node is responsible for one or more non-overlapping subset(s) of the cluster namespace and will process only those requests that access file or directory objects in the partitioned namespace that the node controls while redirecting requests designated for other nodes. A non-overlapping subset may be migrated from a source node to a destination node, for example, for load sharing or hotspot mitigation. Migration typically includes maintaining a file virtualization link from the destination node to the source node to permit forwarding of requests by the destination node to the source node during migration of metadata and then migration of data from the source node. After migration is complete, the file virtualization link is broken and the destination node services requests for the non-overlapping subset from the migrated metadata and data.

  • Patent number: 8117244
    Abstract: A non-distruptive migration of a native volume from a source server to a destination server performed by a file switch involves converting the source native volume to a native with metadata volume. The native with metadata volume is converted to a mirrored native with metadata volume including the source server and the destination server. The destination server includes a mirror copy of the native with metadata volume. The source server is removed from the mirrored native with metadata volume. The mirror copy of the native with metadata volume on the destination server is converted to a destination native volume on the destination server.

  • Publication number: 20090204705
    Abstract: Inserting a file virtualization appliance into a storage network involves configuring a global namespace of a virtualization appliance to match a global namespace exported by a distributed filesystem (DFS) server and updating the distributed filesystem server to redirect client requests associated with the global namespace to the virtualization appliance. Removing the file virtualization appliance involves sending a global namespace from the virtualization appliance to the distributed filesystem server and configuring the virtualization appliance to not respond to any new client connection requests received by the virtualization appliance.

  • Publication number: 20080246676
    Abstract: Antenna assembly for satellite tracking system that includes a plurality of antenna arrangements, each having one or more ports, and all ports connected through transmission lines in a combining/splitting circuit. The antenna arrangements form a spatial element array able to track a satellite in an elevation plane by mechanically dynamically rotating the antenna arrangements about transverse axes giving rise to generation of respective elevation angles and dynamically changing the respective distances between the axes whilst maintaining a predefined relationship between said distances and the respective elevation angles. The combining/splitting circuit provides phasing and signal delay in order to maintain pre configured radiating parameters. The arrangements can be mounted on a rotating platform to provide azimuth tracking. The system provides dynamic tracking of satellite signals and can be used for satellite communications on moving vehicles.
