US Patent:

6791692, Sep 14, 2004

Filed:

Oct 29, 2001

Appl. No.:

10/038090

Inventors:

Gary Powell - Petaluma CA
Richard L. Hazard - Lafayette CA

Assignee:

Lightwind Corporation - San Francisco CA

International Classification:

G01B 1102

US Classification:

356496, 118719

Abstract:

Aspects of the present invention provide novel methods and devices for sampling gas, exciting the sampled gas to emit radiation and detecting in real time from the emitted radiation a plurality of wave bands of an emission spectrum. Energy used to excite the sampled gas may be adjusted based on the detected wave bands. A process may be controlled in real time based on the detected wave bands. Novel interfaces may be used to display portions of the detected wave bands. A known flow of a reference gas may be included in the flow of sampled gases and an unknown flow of an unknown flow gas determined.
