Appl. No.:

10/205411

Inventors:

Richard N. Bostwick - Snoqualmie WA
Gary E. Miller - Auburn WA
David N. Rasmussen - Edmonds WA

Assignee:

The Boeing Company - Seattle WA

International Classification:

H01Q 1300

US Classification:

343853, 343776, 343778

Abstract:

A conformal phased array antenna and associated method of repairing the antenna are provided. The antenna has individual subassemblies or line replaceable units such that the antenna can be repaired without completely removing the entire antenna. The antenna generally includes a planar antenna subassembly including an array of RF modules disposed in a reference plane. The antenna also typically has a contoured waveguide subassembly including a contoured aperture honeycomb structure. The contoured aperture honeycomb structure defines a number of passages that are in communication with respective RF modules. The exterior surface of the contoured aperture honeycomb structure that faces away from the planar antenna subassembly is contoured such that at least portions of this surface are at an oblique angle with respect to the reference plane. This contoured surface may advantageously be shaped to match the contour of the surface of the structure to which the antenna is mounted.

Assignee:

International Classification:

H01Q 1/28

US Classification:

343705, 343785

Abstract:

A phased array antenna system on an aircraft that incorporates a choke plate that significantly attenuates sidelobes of the antenna beam pattern at elevation angles that would cause RF interference with ground-based terrestrial wireless networks. The choke plate includes a plurality of choke grooves that substantially circumscribe the antenna aperture. The choke plate has an upper surface that is positioned generally coplanar with the upper surface of the antenna aperture. The grooves of the choke plate may be filled with a dielectric material. The choke plate provides a smooth aerodynamic component that significantly attenuates beam scattering, and thus the radiation pattern sidelobes of the antenna at or below the horizon, when the aircraft is in flight.

Inventors:

David J. Rasmussen - Redmond WA, US
Simon P. Clarke - Seattle WA, US

Assignee:

Microsoft Corporation - Redmond WA

International Classification:

G06F 12/00
G06F 17/30

US Classification:

707203, 707201, 707205

Abstract:

Methods, systems, and computer program products disambiguate a globally universal identifier (GUID) within a file after the file is duplicated. The method involves generating a GUID for the file, generating a location identifier that defines a unique location of the file when the GUID was generated, and storing the location identifier in association with the GUID. The method also involves opening and examining the file, determining whether the location identifier matches a current location of the file, and in response to determining that the location identifier does not match the current location, generating a new GUID and replacing the GUID with the new GUID. Additionally, the method may also involve remapping references mapped to the GUID in the file to the new GUID and resetting the location identifier to match the current location.

International Classification:

H01Q 13/00

US Classification:

343872, 343719

Abstract:

An antenna aperture for mounting on the outside mast structure of a submarine is disclosed. The antenna aperture is designed to withstand hydrostatic pressure cycles as would be experienced by a submarine. The antenna is constructed of a highly corrosion resistant housing upon which a wide angle impedance (WAIM) cover designed to meet antenna RF requirements is integrated.

International Classification:

G06F 7/00
G06F 17/30

US Classification:

707 10, 7071041, 707201

Abstract:

Many different users may access, revise and update the same shared object simultaneously through several different transports. Revisions to the shared object are automatically synchronized such that all users can view the revisions to the shared object. Conflicting revisions are reconciled and merged into a current version of the shared object. A client may request the current version of the shared object from a store when the current version of the shared object is not available from the store. The current version of the shared object is synchronized with the client when the store receives the current version of the share object.

International Classification:

H04L 9/32

US Classification:

726 17, 726 19, 726 4, 726 18

Abstract:

A non-modal notification user interface element is displayed persistently but unobtrusively such that a user may easily determine that authentication credentials are required by a background synchronization process. The non-modal notification is configured such that it may be ignored by the user such that their workflow is not interrupted. The background synchronization continues to synchronize the data it can even though the background synchronization may require authentication credentials for a subset of the data to be synchronized. The user may select the non-modal notification user interface element at any point in time in order to supply the required authentication credentials. The non-modal notification is removed from the display when there are no further authentication credentials required.

Assignee:

Microsoft Corporation - Redmond WA

International Classification:

G06F 15/16

US Classification:

709217

Abstract:

Tools and techniques are described for merging versions of documents using multiple masters. These tools may provide methods that include syncing a first peer system with at least a second peer system, with the first and second peer systems receiving respective instances of a document for collaborative editing. The first and second peer systems may maintain respective version histories associated with the document, with these version histories capturing and storing revisions occurring locally at the first and second peer systems. The first and second peer systems may exchange version histories, and merge these version histories.

International Classification:

US Classification:

709204, 709205, 709227

Abstract:

Many different users may access, revise and update the same shared object simultaneously through several different transports. Clients may communicate asynchronously by accessing the shared object through a physical server. Clients may also communicate synchronously by accessing the shared object through a peer-to-peer network. A manifest file associated with the shared object identifies the locations where other versions and instances of the shared object are stored. The shared object and the associated manifest file allow a client to transition seamlessly between local access, synchronous and asynchronous communication such that the user is not aware that the mode of communication has changed. A user may change location and any available data sharing transports are automatically identified. Thus, the user may access a shared object and collaborate with other authorized users through different mechanisms.
