A method and apparatus for a pump and a pump control system. The apparatus includes pistons integrally formed in a diaphragm and coupled to the diaphragm by convolutes. The convolutes have a bottom surface angled with respect to a top surface of the pistons. The apparatus also includes an outlet port positioned tangentially with respect to the perimeter of an outlet chamber. The apparatus further includes a non-mechanical pressure sensor and a temperature sensor coupled to a pump control system. For the method of the invention, the microcontroller provides a pulse-width modulation control signal to an output power stage in order to selectively control the power provided to the pump. The control signal is based on the pressure within the pump, the current being provided to the pump, the voltage level of the battery, and the temperature of the pump.

An appliance controller is provided featuring one or more modules configured for providing power to an appliance that receives fluid from a fluid supply system, for receiving a fluid supply system signal indicating that the fluid is not being provided to the appliance and for disconnecting the power to the appliance. The one or more modules may take the form of an appliance controller circuit having a first circuit part configured for providing power to an appliance that receives fluid from a fluid supply system; and a second circuit part configured for receiving a fluid supply system signal indicating that the fluid is not being provided to the appliance and disconnecting the power to the appliance. The appliance controller may form part of an appliance controller system having appliances, appliance controllers and the fluid supply system.

The present invention provides a system featuring a dispenser for providing fluid from multiple reservoirs to an appliance or other suitable device; and a multiple tubing arrangement coupled between the dispenser and the multiple reservoirs of fluid, the multiple tubing arrangement being responsive to a vacuum provided from the dispenser, for drawing the fluid from the multiple reservoirs so as to deplete the multiple reservoirs at relatively equal amounts based on the Venturi effect. The multiple tubing arrangement comprises a primary inlet tube for arranging in a primary reservoir, an auxiliary inlet tube for arranging in an auxiliary reservoir, and a feed connector tube arranged between the primary inlet tube and auxiliary inlet tube. The primary inlet tube is coupled to the auxiliary inlet tube so as to provide a proportional vacuum and siphoning effect. The multiple tubing arrangement siphons and depletes the fluid from the primary reservoir and the auxiliary reservoir based on the Venturi effect.

Embodiments of the invention provide a pump control circuit for use with a pump. The circuit includes a pressure sensor capable of sensing a pressure in the pump and a microcontroller coupled to the pressure sensor and to the pump. The microcontroller switches operation of the pump between a high-flow mode and a low-flow mode. When in the high flow mode, the microcontroller limits a current provided to the pump to a high-flow current limit value that is not dependent on the sensed pressure. When in the low flow mode, the microcontroller limits the current provided to the pump to a low-flow current limit value that is less than the high-flow current limit value and that changes depending on the sensed pressure.

Embodiments of the invention provide a method of controlling a pump. The method includes sensing a pressure in the pump and entering a low-flow mode when the sensed pressure in the pump is greater than a low pressure threshold. The method also includes reducing power to the pump when the sensed pressure is greater than a shut-off pressure during the low-flow mode and there is flow through the pump until the sensed pressure is less than the shut-off pressure. The method further includes turning the pump off when in the low-flow mode the sensed pressure is greater than the shut-off pressure and there is no flow through the pump.
