US Patent:

55198830, May 21, 1996

Filed:

Feb 18, 1993

Appl. No.:

8/018829

Inventors:

Theodore C. White - Tustin CA
Chung W. Wong - Dana Point CA
Kha Nguyen - Anaheim CA
Jayesh V. Sheth - Mission Viejo CA
Craig W. Harris - Lake Forest CA

Assignee:

Unisys Corporation - Blue Bell PA

International Classification:

G06F 1300
G06F 1320

US Classification:

395840

Abstract:

An interbus interface module enables storage and transfer of commands, messages and data between parallel a dual system bus operating on a first protocol and a subrequestor bus operating on a second protocol. The interface module serves a first group of requestors, such as multiple processors and main memory, for handling data transfers to and from the subrequestor bus via said dual system buses while also handling data transfers to and from a second group of requestors connected to the subrequestor bus.

Abstract:

A system for three-dimensional hyperspectral imaging includes an illumination source configured to illuminate a target object; a dispersive element configured to spectrally separate light received from the target object into different colors; and a light detection and ranging focal plane array (FPA) configured to receive the light from the dispersive element, configured to acquire spatial information regarding the target object in one dimension in the plane of the FPA, configured to acquire spectral information in a second dimension in the plane of the FPA, wherein the second dimension is perpendicular to the first dimension, and configured to obtain information regarding the distance from the FPA to the target object by obtaining times of flight of at least two wavelengths, thereby imaging the target object in three dimensions and acquiring spectral information on at least one 3D point.
