US Patent:

57933324, Aug 11, 1998

Filed:

Apr 6, 1993

Appl. No.:

8/044097

Inventors:

William Douglas Fowler - Plano TX
Stephen David Levin - Richardson TX
Brian Sean Brown - Wauwatosa WI

Assignee:

Raytheon TI Systems, Inc. - Lewisville TX

International Classification:

H01Q 2108
H01Q 2128
H01Q 2129
H01Q 2130

US Classification:

343705

Abstract:

A fixed body wide field-of-view conformal antenna array suitable for broadband precision direction finding on missile platforms. The array is configured as multiple sub-arrays of spiral antennas that cover particular regions within the desired field-of-view of the entire array. A lower cost, more reliable and more accurate direction finding solution for missile needs is provided, primarily by the elimination of conventional radomes and antenna gimbal structures. The array can be configured to include multi-mode sensors.

International Classification:

G06F 1574

US Classification:

364419

Abstract:

A data processing system provides annotation of a document through an electronic tablet, a keyboard and an audio assembly. An annotatable document is generated from a window of a multiwindow support program running independently of the annotation program in the data processing system. For each window of the multiwindow program, a working document is generated and is annotatable by the annotation program and apparatus. An annotatable document is also generated from the whole screen view of overlapping windows produced during execution of the multiwindow support program. Annotated working documents may be subsequently stored in and thereafter retrieved from the database of the multiwindow support program.
