  • Patent number: 7734781
    Abstract: In a shared storage infrastructure accessible by more than one customer, the shared storage infrastructure is separated into a plurality of logical storage areas. A customer is associated with at least one logical storage area within the shared storage infrastructure. The customer and its logical storage areas are associated with at least one port in the shared storage infrastructure. Each customer has access only to the logical storage areas associated with the customer and cannot access the logical storage areas of any other customer. The shared storage infrastructure provides policy based storage management to each customer, that is, each customer appears to have access to a non-shared storage subsystem. By providing a virtualization layer, a customer may be given the ability to manage its own storage needs.
    Type: Grant

  • Patent number: 6198445
    Abstract: A conformal load bearing antenna structure for attachment to an aircraft having an outer skin. The conformal load bearing antenna structure comprises a top face sheet and an end fed radiating element disposed thereon. Disposed adjacent to the top face sheet is a dielectric and a structural core disposed adjacent to the dielectric. In the preferred embodiment, a bottom face sheet is disposed adjacent to the structural core and an absorber is disposed adjacent to the bottom face sheet. Accordingly, the top face sheet, the dielectric, the structural core, and the bottom face sheet are configured to provide structural strength to the aircraft when the antenna is attached to the outer skin thereof.

  • Patent number: 6175336
    Abstract: A structural endcap antenna for a vertical tail of an aircraft. The endcap antenna comprises an outer skin having an inner surface and an antenna element disposed adjacent to the inner surface of the outer skin. The antenna element is in electrical communication with an RF signal source. Disposed adjacent to the antenna element is an inner support structure electrically bonded thereto. The antenna element and the inner support structure are excited by the RF signal source and provide structural support to the endcap antenna.
