Filed:

Aug 29, 2002

Appl. No.:

10/230517

Inventors:

John Higgins - Santa Ana CA, US

Assignee:

SensorMedics Corporation - Yorba Linda CA

International Classification:

G01P 506
G01F 168

US Classification:

7386185, 7320427, 12820024

Abstract:

A Kelvin sensed hot-wire anemometer includes four electrically conductive pins and a filament welded to all four pins, preferably using a single filament. A current source is coupled to the two innermost pins so as to provide current flow in the segment of filament between the two innermost pins. The two outermost pins are coupled to a high impedance voltage sense amplifier that senses the voltage drop across the energized segment of filament between the two innermost pins. The resistance of the filament is determined based on the current provided to the filament and the measured voltage. The Kelvin sensed hot-wire anemometer can be used in a number of applications, including, but not limited to medical devices that measure gas flow rates during inhalation and exhalation.

Abstract:

A lavatory monument assembly configured to be positioned in the interior of an aircraft. The modular lavatory monument assembly includes first, second, third and fourth walls that cooperate to form an enclosure that defines a lavatory interior, a door positioned on one of the first, second, third, or fourth walls, and an opening on the fourth side that is open to an exterior of the enclosure. A seat is at least partially positioned in the opening. The seat includes a seat back and a seat portion that is pivotal between a storage position and a deployed position. In the deployed position the seat portion extends outside of the opening.
