Pulsed infrared sensor to detect the presence of a person or object whereupon a solenoid is activated to regulate fluid flow
First Claim
1. Pulsed infrared sensor including a solenoid to detect the presence of a person or object whereupon the solenoid is activated to regulate fluid flow, comprising:
- a control circuit having a power supply for supplying required power to said solenoid for operation thereof;
means including at least one LED (light-emitting diode) for transmitting pulses of infrared light energy with a digital code towards the person or object;
means operatively associated with said transmitting means and responsive only to said digital code for receiving the light energy reflected from the person or object;
a microcontroller responsive to operational amplifier means delivering a train of pulses for recognizing said train of pulses;
means for controlling the distance at which the person or object can be detected;
means for determining the amplitude of the signal reflected and received by said receiving means, including means for adjustment of the amplitude; and
adjustment means coupled with said solenoid and operatively coupled with said microcontroller including means for setting a binary coded decimal switch means for controlling the duration that the sensor will operate the solenoid.

Abstract
Pulsed infrared sensor including a solenoid to detect the presence of a person or object whereupon the solenoid is activated to regulate fluid flow, including a microprocessor for receiving inputs from a plurality of sources and to provide outputs to a plurality of receivers for the control of the fluid flow, and a collection of inputs receivable by the microprocessor from sources activated in response to infrared rays received after transmission from an infrared transmitter including a remote transmitter associated with the microprocessor to activate a fluid supply control to control the supply of fluid to the fixture.
