US Patent:

7468690, Dec 23, 2008

Filed:

Aug 10, 2006

Appl. No.:

11/463655

Inventors:

Patrick Anthony Green - Glenwood MD, US
William Blackmore Dixon - Glen Burnie MD, US

Assignee:

Northrop Grumman Systems Corporation - Los Angeles CA

International Classification:

G01S 7/40

US Classification:

342174, 342175

Abstract:

A system for calibrating waveform generators and receivers of non-overlapping electronic scanning antennas includes a first sub-array, a second sub-array and a calibration cable. The first sub-array includes a first waveform generator, a first receiver, and a first switch assembly. The second sub-array includes a second waveform generator, a second receiver, and a second switch assembly. The calibration cable is configured to selectably form a common calibration path between the first and second sub-arrays based on a position of the first and second switch assemblies. The first and second switch assemblies are configured to enable calibration of the second receiver using an input from the first waveform generator via the calibration cable.

Abstract:

Transformable furniture is provided, which is a unitary structure which itself transforms between seating and a play space. More specifically, the furniture has first and second frame members which move towards each other to form a couch and away from each other to form a play space, such as a playhouse.

Abstract:

A light-weight, integrated enclosure and fully-adjustable mounting and support system for transport and use of mobile electronic equipment in the field. A curved upper shell and flat base of sandwich panel construction are connected by reinforced plastic members to form a lightweight enclosure which can be mounted on a truck for transport. The fully adjustable mounting and support system includes rails mounted within the enclosure on which a series of frame elements are horizontally movable to accomodate electronic equipment of varying widths between the frame elements. The frame elements are also lightweight extrusions and include an elastomeric pad engaged in a vertical channel to provide infinite vertical adjustability in mounting the equipment to the frames. The enclosure is shaped for efficiently housing the equipment, reducing aerodynamic drag, and providing superior structural strength and stiffness. A conductive coating or screen may be applied to the enclosure to provide electromagnetic interference protection.
