1. A sensing and valve operating means for remotely controlling a faucet, comprising:
- (a) means to sense the presence of an object near a faucet outlet,(b) means to energize a solenoid in response to the presence of the object,(c) means to calculate the time when the solenoid is energized,(d) means to remove the energy from the solenoid after a predetermined time interval, notwithstanding that the means to sense the presence of an object is sensing an object, and(e) means for rendering inoperative said means to energize until after the object is removed from near the faucet outlet.

Abstract
A sensing and valve operating mechanism for remotely controlling a faucet can be used with an anti-scald faucet valve and can be provided on a faucet by a kit. The mechanism senses the presence of an object near a faucet outlet, energizes a solenoid in response to the presence of an object, and calculates the time when the solenoid is energized. Energy is removed from the solenoid after a predetermined time interval notwithstanding that the presence of an object is still being sensed. The solenoid cannot be re-energized until after the object is removed from near the faucet outlet.

8. A sensing and valve operating means for remotely controlling a faucet, comprising:
-
(a) means to sense the presence of an object near a faucet outlet, the sensing means including a light emitting diode (LED) driven by a pulse generator, and a light detector driven in synchronism with said LED to detect only pulses reflected by the object from the LED, (b) means to energize a solenoid in response to the presence of the object, (c) means to calculate the time when the solenoid is energized, and (d) means to remove the energy from the solenoid after a predetermined time interval, notwithstanding that the means to sense the presence of an object is still operative. - View Dependent Claims (9, 10, 11, 12, 13)
