Appl. No.:

09/910681

Inventors:

Gregory Evans - Tustin CA, US
Charles Patrick - Houston TX, US
Mathias Schmidt - Konstanz, DE
Zhen Fan - Houston TX, US

International Classification:

A61K048/00

US Classification:

514/044000, 424/093210

Abstract:

The present invention relates to compositions and methods for the stimulation of nerve cell growth and the regeneration of nerve tissue. Using engineered “helper” cells and nerve growth conduits, in vivo stimulation of nerve cell growth, for example, in damaged or diseased tissues, is achieved.

Appl. No.:

5/359591

Inventors:

Gregory W. Evans - Santa Ana CA
Robert L. Caswell - Placentia CA

Assignee:

Rockwell International Corporation - El Segundo CA

International Classification:

G06F 314

US Classification:

235151

Abstract:

A digital character generator method and system encode characters based on a normalized quad in accordance with coordinates of initial starting points of outlines of the character and variational parameters defining changes in those outlines such as slope and curvature. All characters of all formats are encoded for a maximum point size display. Vertical scaling factors permit character generation at any desired point size display. Horizontal scaling factors are employed both for transforming computations based on the encoded parameters for the normalized quad to a desired point size of display and also to adapt cyclic computations to the stroking density of a display CRT.

Abstract:

An autonomous navigational system for an airborne vehicle is disclosed which automatically updates its position and heading coordinates at each of a plurality of checkpoints along a preselected flight path. Prestored in a memory of the navigational system is a plurality of reference map images respectively associated with the plurality of checkpoints. Each reference map image is comprised of a plurality of terrain features associated with the terrain about an associated checkpoint. In operation, an acquisition unit senses an image of local terrain at each checkpoint. The relative sizes of reference and sensed map images vary with the mission requirements. A terrain feature extractor detects a plurality of terrain features contained in the sensed map image. The detected terrain features in the sensed map image are selectively matched in a feature pattern matcher against the terrain features of the associated reference map image to determine the position and orientation of the sensed map image within the associated reference map image. The output of the feature pattern matcher comprises error signals which are used by an inertial guidance system to update the position and heading coordinates of the airborne vehicle.
