  • Publication number: 20120133549
    Abstract: An antenna architecture for hemispherically-scanning active electronically scanned arrays (AESA). The antenna architecture utilizes variable diameter disks of antenna elements configured in a conical implementation. The antenna elements are oriented such that the element boresight is normal to the surface of the conical structure. Beamforming takes place on each disk first, and them separately in combining the signals from each disk, thereby reducing complexity. The antenna optionally utilizes disks of antenna elements of the same diameter to form a cylindrical antenna, which when combined with a conical configuration create enhanced sectors while maintaining a hemispherical coverage capability. Further, use of two conical configurations can produce a fully spherical coverage capability.

  • Patent number: 8185633
    Abstract: A system and method for offloading network processes from main processors of a storage system and performing them on parallel processing modules. Embodiments of the present invention improve performance of a clustered storage system by performing certain network processes in an accelerator module of a storage system node. The accelerator module receives multi-protocol protocol data units (PDUs) from a network interface, performs protocol operations on the PDUs to form file system requests and passes the file system requests to a local D-module. If a file system request is directed to a non-local D-module in the cluster, the accelerator module repackages the request for transmission to the appropriate D-module and passes it back to the network without using local D-module processing resources or passing data over the system bus.

  • Publication number: 20110267218
    Abstract: A method of using a discriminant analysis and Kalman filter cascade to improve the accuracy of point of origin solutions. Tracking information about a potential target is utilized by an initial discrimination function to classify the target as a projectile. Using that information, the output of a first Kalman filter is fed into an additional discrimination function to further classify the type or sub-class of the projectile. A second Kalman filter can employ type-specific information to obtain a point of origin solution with increased efficiency and accuracy.
