US Patent:

20120327378, Dec 27, 2012

Filed:

Jun 27, 2011

Appl. No.:

13/169984

Inventors:

Eric Joseph Harvey - Seattle WA, US
Ty Aaby Larsen - Everett WA, US
Richard A. Cote - Mill Creek WA, US

Assignee:

THE BOEING COMPANY - Chicago IL

International Classification:

G03B 21/16
G03B 21/14

US Classification:

353 52, 353119

Abstract:

A method and apparatus comprising a projector system and a structure connected to the projector system. The projector system is configured to project an image on an exterior surface of an aircraft. The structure is configured to be connected to the aircraft and has a shape configured to reduce an undesired airflow caused by the projector system when the aircraft is in flight.

International Classification:

G01F 23/292
G01N 9/00

Abstract:

Systems and methods that use a differential spectral liquid level sensor to measure the level of liquid in a reservoir (e.g., a fuel tank or other storage container). The use of a differential spectral liquid level sensor solves the problem of common-mode intensity variations (i.e., intensity variations not due to the level of the liquid) by having two different wavelengths propagate through the same optical path but have different spectral attenuations in the liquid. By determining the ratio of the received optical powers, common-mode intensity variations can be neutralized, thereby enhancing the accuracy of the received power reading and the resulting liquid level indication.
