Filed:

Dec 1, 2005

Appl. No.:

11/291153

Inventors:

Kevin Marc Morrissey - Xenia OH, US
Jason Alan Schaefer - Galloway OH, US

Assignee:

Trimble Navigation Limited - Sunnyvale CA

International Classification:

G02B 27/10
G02B 27/12

US Classification:

359640, 359618

Abstract:

A system to produce orthogonal beams includes a laser diode operating in conjunction with a collimating lens, an aperture, and a simple compact optic. Three collimated beams are directed toward an optic comprised of components that are bonded together. Beams are reflected from two optical components at right angles to produce plumb beams. Additionally, a beam is reflected from the optic at a right angle, as well as transmitted through the optic, to produce square and level beams. All four beams are orthogonal to each other, have relatively equal power, and are aligned and oriented so as to appear to be originating from a coincident point. Optionally, a fifth orthogonal beam may be produced. An optic in the shape of a cuboid comprised of six small components is also disclosed.

US Classification:

359640, 359618

Abstract:

A system to produce orthogonal beams includes a laser diode operating in conjunction with a collimating lens, with or without an aperture, and a simple compact optic. At least one collimated beam is directed toward an optic comprised of components that are bonded together. Beams are reflected from at least one optical components at right angles to produce a plumb beam. Additionally, a beam is reflected from the optic at a right angle, as well as transmitted through the optic, to produce square and level beams. All beams are orthogonal to each other, have relatively equal power, and are aligned and oriented so as to appear to be originating from a coincident point. An optional orthogonal beam may be produced. An optic in the shape of a cuboid comprised of six small components is also disclosed.

US Classification:

356 73, 356301, 356318, 356417, 2504611

Abstract:

A biological and chemical detection system is provided that detects and identifies biological and/or chemical particulates of interest. The biological and chemical detection system comprises a collector, a first optical device, a second optical device and a processor. The collector is configured to deposit particulates drawn from a fluid stream onto a sample substrate to define a sample area. The first optical device derives first data relative to at least a portion of the sample area, which is analyzed to determine at least one field of view and/or specific target location. The second optical device then interrogates the sample area at each determined target location, e. g. , using Raman spectroscopy, to produce interrogation data. The processor determines whether the sample area includes predetermined biological or chemical particulates of interest based upon an analysis of the interrogation data and triggers an event such as an alarm or message if the predetermined biological or chemical particulates of interest are identified.

US Classification:

435 39, 4352881

Abstract:

A system for conducting the identification and quantification of micro-organisms, e.g., bacteria in urine samples which includes: 1) several disposable cartridges for holding four disposable components including a centrifuge tube, a pipette tip having a 1 ml volume, a second pipette tip having a 0.5 ml volume, and an optical cup or cuvette; 2) a sample processor for receiving the disposable cartridges and processing the urine samples including transferring the processed urine sample to the optical cups; and 3) an optical analyzer for receiving the disposable cartridges and configured to analyze the type and quantity of micro-organisms in the urine sample. The disposable cartridges with their components including the optical cups or cuvettes are used in the sample processor, and the optical cups or cuvettes containing the processed urine samples are used in the optical analyzer for identifying and quantifying the type of micro-organism existing in the processed urine samples.
