Filed:

Jul 21, 2004

Appl. No.:

10/895675

Inventors:

Bryan L. Croft - San Diego CA, US

Assignee:

United States of America as represented by the Secretary of the Navy - Washington DC

International Classification:

G06T 15/00

US Classification:

345629

Abstract:

An object selection of 3D objects in a computer-generated 3D environment method and system. The method includes defining a 3D space in a computer-generated environment. The method further includes identifying a plurality of 3D objects within the 3D space. Then, determining a line of selection though the 3D space. Further, determining a closet object of the plurality of 3D objects via comparative measurements between the plurality of 3D objects and the line of selection. In addition, enabling the closest object to be selected.

Appl. No.:

International Classification:

G06F017/50

US Classification:

716/020000

Abstract:

A self-adaptive rezoning process that employs a system of rezoning indicators for the automated detection of distorted elements during deformation. Linear isoparametric quadrilateral elements using selective reduced integration are employed to predict the remeshing points based upon finite-element modeling assumptions of structural problems involving large deformations and strains. Element geometrical measures are characterized in terms of aspect ratio, taper ratio and skew angle to permit the degree of element distortion expressed in these terms to be compared to an ideal element similarly expressed. The finite-element mesh is evaluated, element by element, to quantify the geometrical relationships required to properly quantify the amount of distortion.

International Classification:

G08B 2100

US Classification:

340605

Abstract:

A leak detector for detecting a leak of an electrically conductive fluid m a vessel comprises an electrically conductive wire having a melting temperature less than an internal temperature of the vessel and greater than the external temperature of the vessel. The wire is stitched to a heat resistant fabric to hold the wire in place and to thermally and electrically insulate the wire when no leaking fluid is present. Detector means electrically connected to the wire outputs an electrical signal if the wire is fused by leaking fluid permeating the fabric.

International Classification:

G06T 11/20
G06F 17/30
G06F 3/0482

Abstract:

A treemap visualization system and method which provides for real time visualization of variable adjustments to represented criteria in a treemap. The treemap visualization system and method is implemented on a computer system and employs a database having a plurality of data items to be visualized. A treemap visualization layout may be formulated with tiles based on data elements for each data item. A variable modifier module enables the adjustment of weighting of the data elements for each data item when the treemap visualization layout is formulated. Data items are sorted into discrete levels so that a plurality of stackable tile layers can be formulated. Alerts are generated when layout events are related to the physical properties or positioning of the tiles in the treemap visualization layout.
