Abstract: A convertible fluid dispenser for dispensing personal care hygiene products has a chassis adapted to accept either a manual actuating unit or an automatic actuating unit, for upgrading or maintenance.

Abstract: A foam pump assembly for dispensing foam comprises a dual piston pump engine having an air cylinder and fluid cylinder each with pistons, a mixing chamber in communication with the liquid cylinder for receiving liquid, and in communication with the air cylinder for receiving air, an outlet chamber providing a flow path with turns, whereby when air and fluid is fed into said mixing chamber foam is created which passes into the outlet chamber, through the flow path and out of the pump outlet.

Abstract: A faucet control apparatus adapted for retrofitting in a faucet system having a faucet spout removable from a faucet base comprises a body having a water inlet adapted to be connected to the outlet side of a faucet base, and a water outlet adapted to accept the water inlet of a faucet spout, a sensor in the body for detecting the presence of a person's hands beneath the outlet side of the faucet spout, and a water valve in the body responsive to the sensor, which valve is in a normally closed position but which opens in response to the presence of a person's hands beneath the outlet side of the faucet spout as detected by the sensor.

Abstract: An adapter for retrofitting a conventional gooseneck faucet to allow for touch-free activation. The sensor unit of the adapter is attached by simply passing it over the spout of the gooseneck faucet and towards the base of the faucet where it is locked in place by a clamp. Once in place, the sensor unit uses infrared light to sense the proximity of hands under the faucet. When hands are sensed, the control unit mounted under the sink will activate the faucet for as long as hands remain under the faucet.
