G06F 7/00
G06N 5/02

US Classification:

706 47, 707609

Abstract:

A system and method for interactive knowledge visualization are provided. In some embodiments, a method for interactive knowledge visualization includes receiving, at a knowledge visualization server, a request for one or more visualizations; retrieving data associated with the one or more visualizations from one or more databases; converting the data associated with the one or more visualizations into visualization data, the visualization data being operable to be converted by a client into the one or more visualizations; transmitting, to a first client and a second client, the visualization data; receiving, at the knowledge visualization server, a modification request from the first client, the modification request indicating a desired modification to at least one of the one or more visualizations; modifying, in response to the modification request, the visualization data associated with the one or more visualizations; and transmitting, to the first client and second client, the modified visualization data.

Appl. No.:

10/360967

Inventors:

John Crews - Dallas TX, US

International Classification:

G08B005/00

US Classification:

340/815860

Abstract:

A display simultaneously providing two sets of data. The display includes a moveable needle rotated about a pivot point located at the base of the length of the needle. The position of the needle upon a background provides an indication of a first set of data. The needle may also be incrementally illuminated or highlighted to indicate a measured value of a second set of data. The illumination may be a plurality of lights affixed to the length of the needle. Additionally, the lights may optionally be color coded to indicate a specific range value.

Assignee:

Raytheon Company - Waltham MA

International Classification:

G06T 7/00

US Classification:

382154

Abstract:

In one aspect, a computerized method to automatically detect buildings includes determining if each point of a set of filtered points is on a line by processing the set of filtered points in one pass including a) locating a first point of the set of filter points nearest to a second point of the set of filtered points, b) determining if the distance between the first point and the second point is greater than a distance threshold; c) determining if the first point and the second point have collinearity greater than a collinearity threshold; and d) designating the first point as an endpoint of a line that includes the second point if the distance between the first point and the second point is greater than the distance threshold and if the first point and the second point have collinearity greater than the collinearity threshold.

International Classification:

B60Q 1/26
F21S 41/153
B60Q 1/52

Abstract:

A lighting apparatus includes a light-sheet assembly configured to conform to the rooftop. The light-sheet assembly extends at least one-half the length of the rooftop, and further extends at least one-half the width of the rooftop when mounted to the rooftop. The light-sheet assembly further includes a plurality of light emitting diode (LED) lights that are distributed about the rooftop when the light-sheet assembly is mounted to the rooftop. A controller is communicably coupled to the light-sheet assembly and configured to operate the plurality of LED lights. A roof-mount is affixed to the light-sheet assembly and configured to mount the light-sheet assembly to the rooftop of the emergency vehicle. The lighting apparatus is useful for emergency vehicles.
