Sensor operated water flow control with separate filters and filter retainers
First Claim
1. A sensor for use with a system for controlling the flow of water, including:
- a front plate cover;
at least two separate filter retainers on said front plate cover;
a filter positioned within each said filter retainer for isolating said filters from each other; and
a circuit board and connection means associated with said filters and isolated from public access by said front plate cover for connection to a transmitter and a receiver.

Abstract
A sensor activated unit, e.g., a drinking fountain or a wash basin, for preventing unwanted operation. The sensor has a power on reset circuit that makes use of a resistor capacitor network and a voltage threshold comparing device to create a time delay that will inhibit the operation of the unit for a nominal predetermined time period when current is first supplied to the sensor. The sensor does not activate until a user steps up to the unit and is within a preset range or distance from the unit. Use is made of an infrared sensor for controlling the operation of the unit. Circuitry is provided to control the time of commencement of the operation of the unit, the time period duration of operation, and down time of the unit before it is readied for operation again.

14. The sensor for a system for controlling the flow of water through water supply means, comprising:
-
an outer casing and a front plate cover, two separate filter retainers on said front plate cover, and a filter positioned within each of said separate filter retainers; and a potted circuit board in said casing containing control circuits and wiring for connection to a transmitter and a receiver associated with said filters. - View Dependent Claims (15, 16)

17. A sensor for use with a system for controlling the flow of water, including:
-
an outer casing; two separate filter retainers on said outer casing; a separate filter for each said filter retainer positioned within said each said filter retainer; and a circuit board and connection means associated with said filters and isolated from public access by said outer casing for connection to a transmitter and receiver; and means sealing said filters to said outer casing to form an integral unit therewith to prevent damage to said circuit board and said connection means associated with said filter. - View Dependent Claims (18, 19, 20)
