US Patent:

7155442, Dec 26, 2006

Filed:

Jun 28, 2002

Appl. No.:

10/185525

Inventors:

Peter Carlin - Seattle WA, US
Jun Fang - Sammamish WA, US
Elizabeth Jean O'Neil - Cambridge MA, US
Patrick Eugene O'Neil - Cambridge MA, US

Assignee:

Microsoft Corporation - Redmond WA

International Classification:

G06F 7/08

US Classification:

707101, 707 1, 707 2

Abstract:

Any string in any character set with an arbitrary-leveled weight-based comparison system is transformed into a bitstring in such a way that two transformed strings can be compared byte-by-byte. The resulting bit string has the minimum possible maximum length. The transformed bit strings can be inverted—meaning the original string can be recovered from the transformed string.

Assignee:

The Boeing Company - St. Louis MO

International Classification:

B64C 2102

US Classification:

244204

Abstract:

A passive porosity management device and process for an airfoil which provides a mechanism and method for controlling and modifying the lift, drag and flow field characteristics on an airfoil through the controlled seepage and transference of air utilizing passive porosity through one or more regions of an airfoil and into, and out of, one or more plenum cavities disposed in the interior portion of the airfoil.

Appl. No.:

8/929133

Inventors:

Patrick J. O'Neil - Florissant MO

Assignee:

McDonnell Douglas Corp. - St. Louis MI

International Classification:

B64C 922

US Classification:

244213

Abstract:

A passive porosity airfoil lift management device employed on a leading edge region of said airfoil whereby the lift on said airfoil may be varied and controlled by passively transferring air pressure between the upper surface and lower surfaces of said leading edge region of the airfoil through upper and lower porous skin regions, upper and lower plenum cavities disposed in said airfoil, and controllably monitoring and regulating said passive air pressure transference with at least one valve and a microprocessor.
