Abstract: A pump for a dialysis machine, the pump having a pump chamber and a deformable membrane actuable to pump a fluid from the pump chamber, the pump chamber being substantially conical such that the membrane is actuated to extend into the conical chamber in order to pump the fluid from the chamber.

Abstract: A wave powered energy conversion system operable to convert the motion of ocean waves into a usable form of energy such as electricity. The wave powered energy conversion system includes a storage tank operable to store air pressurized to a pressure greater than that of atmospheric air. A frame assembly circumferentially surrounds the storage tank and consists of sub-frame assemblies organized into quadrants. The frame assembly is movable and has operably coupled thereto a plurality of buoyant objects. A plurality of air pumps are present that are connected to the frame assembly and further connected to an air delivery pipe network. The buoyant objects are operable to move at least a portion of the frame assembly so as to operate at least a portion of the plurality of air pumps so as to produce pressurized air to be distributed to the storage tank.
