Radar Devices For Low Power Applications And Bathroom Fixtures

US Patent:
6388609, May 14, 2002
Filed:
Mar 26, 2001
Appl. No.:
09/817592
Inventors:
Andrew J. Paese - Plymouth WI
Steven M. Tervo - Plymouth WI
Carter J. Thomas - Cedarburg WI
William R. Burnett - Menlo Park CA
David C. Shafer - Menlo Park CA
Fred Judson Heinzmann - Los Altos CA
Assignee:
Kohler Company - Kohler WI
International Classification:
G01S 740
US Classification:
342 27, 342 28, 342114, 342204, 340565, 340567
Abstract:
A fluid flow device includes an actuator, an RF transmitter, a gated RF receiver, and a processor. The RF transmitter is configured and arranged to produce a plurality of pulses of RF energy spaced apart in time to form a sensor field. The gated RF receiver is configured and arranged to receive RF energy reflected by objects within the sensor field. The processor is coupled to the gated RF receiver for evaluating the reflected RF energy. The processor is also coupled to the actuator and is configured and arranged to activate the actuator in response to the reflected RF energy to control fluid flow. In addition, a new low power radar sensor operates by providing radar pulses that are non-uniformly spaced in time. In operation, a burst of pulses is initiated in the transmitter. Between each burst is a period of rest time in which the transmitter is not transmitting RF energy.

Bathroom Fixture Using Radar Detector Having Leaky Transmission Line To Control Fluid Flow

US Patent:
6067673, May 30, 2000
Filed:
Jul 17, 1998
Appl. No.:
9/118255
Inventors:
Andrew J. Paese - Plymouth WI
Steven M. Tervo - Plymouth WI
Carter J. Thomas - Cedarburg WI
William R. Burnett - Menlo Park CA
David C. Shafer - Menlo Park CA
Fred Judson Heinzmann - Los Altos CA
Assignee:
Kohler Company - Kohler WI
International Classification:
E03C 105
US Classification:
4623
Abstract:
Methods and devices for controlling the flow of fluid in fixtures, such as bathroom, restroom, or kitchen fixtures, using a radar detector with a leaky transmission line and fixtures using such methods and devices are provided. A bathroom fixture, in accordance with one embodiment of the invention, includes a fluid conduit, a radar detector for detecting one or more characteristics of one or more objects in a sensor field based on reflected electromagnetic signals from the one or more objects in the sensor field, and a controller coupled to the fluid conduit for controlling a flow of fluid in the fluid conduit in response to the detected one or more characteristics. The radar detector in particular includes a leaky transmission line for transmitting electromagnetic signals to form the sensor field and receiving the reflected electromagnetic signals. In accordance with one aspect of the invention, the sensor field is restricted from selected areas associated with spurious signals, such as areas of flowing water, areas near other fixtures, etc. The use of a radar detector with a leaky transmission line can, for example, improve the control of fluid flow in fixtures, such as bathroom fixtures.

Advanced Touchless Plumbing Systems

US Patent:
6250601, Jun 26, 2001
Filed:
Jul 17, 1998
Appl. No.:
9/118461
Inventors:
Anton J. Kolar - Sheboygan WI
Andrew J. Paese - Plymouth WI
Steven M. Tervo - Plymouth WI
Carter J. Thomas - Cedarburg WI
William R. Burnett - Menlo park CA
David C. Shafer - Menlo park CA
Fred Judson Heinzmann - Los Altos CA
Assignee:
Kohler Company - Kohler WI
International Classification:
E03C 105
E03D 510
US Classification:
25112904
Abstract:
The present invention is a system for controlling a plumbing fixture. The system includes at least two sensors, each sensor including a receiver, and a controller coupled to receive detection signals from the sensors and to generate a control signal in response to the received signals. An actuator is coupled to receive the control signal from the controller and couplable to the plumbing device to act on the bathroom device. The invention is also a method of controlling plumbing fixtures that includes receiving detection signals from a plurality of sensors in a central controller, selecting, in the central controller, which of a plurality of actuators attachable to the plumbing fixtures to operate and directing control signals to the selected actuator to operate the selected actuator.
