Abstract: A wave control circuit disclosed herein may be used to control the operation of various plumbing devices and appliances. The wave control circuit uses a sensor to sense presence of objects in the vicinity of the plumbing device and appliance using the wave control circuit and a control circuit to control the operation of the plumbing device or appliance.

Abstract: This patent discloses tools, methods and systems for dispensing soap. The tools, methods and systems include a draw-back chamber constructed around and in line with the fluid path between a spout assembly for delivering soap to a user and a pump mechanism for supplying the soap. The draw-back chamber contains port openings into the fluid path. When the pump mechanism is actuated to dispense soap, the draw back chamber is collapsed and soap within it is dispensed with the main dose of soap supplied by the pump mechanism. When the pump mechanism is allowed to return to its extended rest state, the draw-back chamber expands, drawing soap into it through the port opening to prevent soap from hanging and dripping at the end of the dispensing tube.

Abstract: A cartridge stores gas under pressure and a container stores a fragrance substance in the housing. A valve controls the release of the gas. An atomizer receives the gas and draws the fragrance substance from the container such that the fragrance substance is sprayed into the atmosphere. A controller opens the valve at predetermined intervals.

Abstract: A shank clip adapted to couple a spout and mounting shaft assembly to a motor housing and support assembly in a fluid dispensing system. The shank clip comprises a first sidewall defining a perimeter that includes a first circular portion that defines a first radius; a second sidewall defining a perimeter that includes a second circular portion that defines a second radius greater than the first radius; and a bottom disposed between the first sidewall and the second side wall to define a channel.

Abstract: An apparatus for dispensing a post-foaming gel soap is disclosed. The dispenser includes a housing containing a first actuator and a second actuator. A motor is operatively connected to said first and second actuator. A circuit is connected to said motor, as well as a sensor assembly and a power supply. In operation, said first and second actuator moves a stem valve and a cylindrical pump located on a reservoir containing a gel soap and an inert propellant gas. The cylindrical pump operates on a piston principle and also closes to prevent any dripping after use. Further disclosed are various methods of accurately dispensing a consistent dose of gel soap.

Abstract: An automatic fluid soap dispensing apparatus and method including a dispensing spout, housing operatively connected to the dispensing spout and the housing adapted to removably receive and hold a fluid soap containing reservoir module in communication with the dispensing spout. The reservoir module has a central axis, and includes a pump mechanism and delivery tube mounted on the reservoir module in alignment with the central axis. The dispensing tube is adapted to move in the dispensing spout when the pump mechanism is actuated.

Abstract: A flexible drive mechanism for a flushing apparatus actuated by movement of a flush handle via an actuation element is disclosed. The drive mechanism includes a housing and flexible drive system in the housing, the flexible drive system including an actuating element operable to move the flush handle between a non-actuating position and a full stop actuating position. The housing further includes first and second bracket halves and first and second removable insert halves for adapting the first and second bracket halves to substantially enclose and engage a bushing and nut and thereby secure said electromechanical flexible actuator to the flush lever of the sanitary fixture.

Abstract: A sensor assembly which is located within a wall is disclosed. The sensor assembly is typically attached to a unit for automatically flushing a toilet or urinal. The sensor assembly includes a housing, a flange, a fastening means, a face plate, a power source, and a sensor. The housing is located in a hole in a wall and fastened by flange and fastening means. The housing will hold the power source and the sensor, which will be enclosed by the face plate. A key which fits in indentations in the face plate and is used to attach and remove the face plate is disclosed. Finally, a method of installing the sensor assembly is disclosed.

Abstract: A flush valve system includes a sensor, a bias circuit, an electrical switch, a mechanical switch, and a flush valve. The bias circuit generates a bias signal when an activation signal is received from the sensor. The bias signal turns on the electrical switch. The mechanical switch turns on just before the electrical switch is turned off. The flush valve is coupled to the electrical and the mechanical switch to initiate fluid flow when the electrical switch is turned on and facilitate the flow until the mechanical switch is turned off. An automatic braking method includes receiving an actuation signal, actuating an electronic switch to initiate a rotation of a switch cam and the opening of a valve, actuating a mechanical switch when a cutout portion of the switch cam is in contact with a portion of the mechanical switch, and closing the valve when the portion of the mechanical switch is outside of the cutout portion.

Abstract: A hands-free faucet includes a sensing plate, a capacitor-based sensor circuit, a non-conductive valve housing, a non-conductive seating ring, and a conductive connector. Preferably, the capacitor-based sensor circuit is electrically connected to said sensing plate. Furthermore, the non-conductive valve housing preferably further comprises a valve inlet and valve outlet. Preferably, said non-conductive seating ring is located between the valve inlet and valve outlet, and is traversed by the conductive connector. In a preferred embodiment, the conductive connector is a metal pin.

Abstract: An automatic flushing actuator that mounts to an overflow pipe in a tank style toilet includes a proximity sensor, a housing enclosing a motor mount and gear assembly, and a rotatably mounted lever on top of the housing. A clamp is adapted to be affixed to the side of the housing and secure the actuator to the overflow pipe. When installing the actuator, the clamp is affixed to the overflow pipe before the housing is mounted onto the clamp. The clamp allows the housing to be removably mounted or locked in position on the clamp. The lever coupled to the top of the housing is rotated to a desired position, and a chain is connected to a handle of the toilet opens the flush valve.

Abstract: A hands-free device includes a sensor, a motor, a pilot valve, a gear train, an arm, and, an override control. The pilot motor opens the pilot valve when an activation signal is received from the sensor. The arm is coupled to the gear train, and the override control is coupled to the arm. The override control is capable of moving the arm between a locked and unlocked configuration.
