Abstract
An automatically controlled faucet-sink system having a fluid dispensing faucet with a sink disposed below that faucet, is controlled by means of a light source-photosensor pair juxtapositioned within a housing mounted on or near the back of the sink so that the light beam and cone of vision of the photosensor are focused at a point intersecting the path of fluid flow from the faucet. Electrical circuitry and valve apparatus are provided which actuate and then cut-off the flow of fluid from the faucet in response to an object under the faucet reflecting light from the light source to the photosensor. Circuitry is also provided for terminating the flow of fluid from the faucet to the sink after a predetermined period has timed out.
