US Patent:

20110026870, Feb 3, 2011

Filed:

Jul 31, 2009

Appl. No.:

12/533941

Inventors:

Glen A. Sanders - Scottsdale AZ, US
Russell W. Johnson - Elmhurst IL, US
Stephen Yates - Arlington Heights IL, US

Assignee:

HONEYWELL INTERNATIONAL INC. - Morristown NJ

International Classification:

G02B 6/00

US Classification:

385 12

Abstract:

Systems and methods for sensing a target analyte. An example sensor includes a tunable light source that provides a substantially single optical mode of light, a detector, a processor, and a resonator. The resonator resonates light provided by the light source at a predefined frequency. The resonator includes a photonic crystal fiber having a solid region that guides a substantially single optical mode of light and at least one hollow channel adjacent to the solid region. The hollow channel receives a fluid from an external source. The hollow channel is coated with a film having a material that is reactive with the target analyte in a manner that changes the optical properties of the film. The detector detects light from the resonator. A predetermined change in the detected signal as determined by the processor indicates presence of the target analyte. The material in the film is reversible.

International Classification:

B64D 13/06
F24F 3/16
B01D 53/30
F24F 11/00

Abstract:

An Environmental Control System includes a sensor, an air purification subsystem, and a controller in communication with the sensor and air purification subsystem. The sensor detects a contaminant in the air and generates a contaminant signal. The controller compares the contaminant signal to a predicted sensory response threshold. When the contaminant signal reaches the predicted sensory response threshold, the controller commands the air purification subsystem to alter a condition in the air.
