Filed:

Jul 31, 2007

Appl. No.:

11/831717

Inventors:

Brian T. Schowengerdt - Seattle WA, US
Ross D. Melville - Issaquah WA, US
Nicholas E. Walker - Springfield OR, US
Bradley E. Sparks - Mercer Island WA, US

Assignee:

Visualant, Inc. - Seattle WA

International Classification:

G06K 9/74

US Classification:

356 71

Abstract:

Spectral information may be employed in process control and/or quality control of goods and articles. Spectral information may be employed in process control and/or quality control of media, for example financial instruments, identity documents, legal documents, medical documents, financial transaction cards, and/or other media, fluids for example lubricants, fuels, coolants, or other materials that flow, and in machinery, for example vehicles, motors, generators, compressors, presses, drills and/or supply systems. Spectral information may be employed in identifying biological tissue and/or facilitating diagnosis based on biological tissue.

Appl. No.:

13/162415

Inventors:

Brian T. Schowengerdt - Seattle WA, US

Assignee:

Visualant, Inc. - Seattle WA

International Classification:

G01P 21/00

US Classification:

702108, 702106, 702189, 702193

Abstract:

Objects such as manufactured goods or articles, works of art, media such as identity documents, legal documents, financial instruments, transaction cards, other documents, and/or biological tissue are sampled via sequential illumination in various bands of the electromagnetic spectrum, a test response to the illumination is analyzed with respect to reference responses of reference objects. The sequence may be varied. The sequence may define an activation order, a drive level and/or temperature for operating one or more sources. Illumination may be in visible, infrared, ultraviolet, or other portions of the electromagnetic spectrum. Elements of the evaluation system may be remote from one another, for example coupled by a network.
