Filed:

Jun 4, 1999

Appl. No.:

9/326783

Inventors:

Mike M. Rozenblatt - Manhattan Beach CA
Robert G. Ratliff - Buena Park CA

Assignee:

MAG Aerospace Industries, Inc. - Compton CA

International Classification:

E03D 1100

US Classification:

4431

Abstract:

A system and method for reducing water consumption in a vacuum toilet on an aircraft. The system and method includes a weight sensing device that is mounted to an aircraft toilet and is responsive to weight applied to the bowl of the toilet. The weight sensing device detects that a toilet user is seated upon the toilet seat when it measures a weight applied to the toilet bowl. On the other hand, the weight sensing device detects that a toilet user is standing when the weight sensing device does not measure a weight applied to the toilet bowl. A flush control unit is connected to the weight sensing device and controls the amount of water utilized in the flushing of the toilet. When the toilet is flushed and the weight sensing device has detected that a toilet user has sat upon the toilet seat, the flush control unit commands that a standard amount of water be used to remove the solid waste of the toilet user. On the other hand, when the toilet is flushed and the weight sensing device has detected that the toilet user has stood, the flush control unit commands that a small amount of water be used thereby saving water.

Inventors:

- RL Alkmaar, NL
Andreas Metz - Dillenburg, DE
Lucas Nastase - Lahnau, DE
Robert Ratliff - Buena Park CA, US

Assignee:

Driessen Aerospace Group N.V. - RL Alkmaar

International Classification:

H01M 8/04
B64D 41/00
B64D 11/00

US Classification:

429410, 429 50, 429400

Abstract:

Disclosed are crew rests that may be powered by the outputs of a fuel cell system or other suitable power source. For example, but not limited to, a combination of the water, oxygen-depleted air, thermal energy and/or electrical energy generated by the fuel cell system may be used to supply the crew rest with its various power and water needs, helping to make the crew rest autonomous from the aircraft's main power systems.
