First Claim
Patent Images
1. A control device for a sanitary fixture comprising:
- a detection unit responsive to presence of a user of a sanitary fixture and including at least an electrically operated transmitter and a receiver responsive to signals from said transmitter;
a control and evaluating circuit connected to said detection unit for controlling electrical energization thereof and evaluating an output from said receiver for operating the sanitary fixture in a normal mode of operation;
an electric energy source packaged with said unit and said circuit and connected to said circuit for supplying electrical energy for said detection unit and said circuit;
means connected with said circuit for activating an energy-sparing mode of operation of said device in response to initiation of said energy-sparing mode of operation by a fabricator of the device; and
means for operating said circuit and said unit in said energy-sparing mode at low drain of said source substantially below a current drain during said normal mode, said energy-sparing mode being deactivated upon installation of the device for operation thereof in said normal mode.

Abstract
A sanitary fixture permits a battery to be packaged with a control and evaluation circuit and a proximity detector for automatic control of a valve. The circuit is set at the factory after final testing with the battery in place to an energy-sparing mode which is maintained, e.g. by a sticker over the receiver of the infrared proximity detector. The normal mode is activated by an infrared signal applied when the unit is installed.

16. A method of installing and operating a sanitary fixture, comprising the steps of:
-
(a) at a location remote for an installation site, fabricating a control device for a sanitary fixture by packaging together a detection unit responsive to presence of a user of a sanitary fixture and including at least an electrically operated transmitter and a receiver responsive to signals from said transmitter, a control and evaluating circuit connected to said detection unit for controlling electrical energization thereof and evaluating an output from said receiver for operating the sanitary fixture in a normal mode of operation, and an electric energy source connected to said circuit for supplying electrical energy for said detection unit and said circuit; (b) after said packaging in step (a) subjecting said device to final tests using said source to supply electric current thereto; (c) upon finding said device to satisfy said tests, terminating the normal mode of operation of said device and thereafter activating an energy-sparing mode of operation of said circuit for operating said circuit and said unit at low drain of said source substantially below a current drain during said normal mode; (d) thereafter packing said device as a finished product, storing the packed device and shipping the packed device to said installation site; (e) removing packing from said device at said installation site; (f) thereafter installing said device at said site; and (g) then deactivating said energy-sparing mode of operation of said circuit and initiating said normal mode. - View Dependent Claims (17, 18, 19, 20)
