| 20110131972 | Acoustic Turbine - A method and apparatus generates kinetic and electrical energy using sound waves and is believed to be particularly useful in high efficiency motors and electrical generators. In particular, the method and apparatus uses sound waves as a catalyst to convert ambient heat energy into kinetic and/or electrical energy. In one embodiment, sound waves at particular frequencies are propagated across one side of a plate or other barrier element, causing flow of fluid (e.g. air) across the surface of the plate which, in turn, causes a reduction in the ambient fluid (air) pressure near the surface of the plate. The difference in fluid pressure on opposite sides of the plate results in net positive thrust on the plate, thereby causing movement of the plate. This movement can be harnessed using, for example, a windmill type of rotor and stator arrangement to generate useful kinetic and electrical energy. | 06-09-2011 |
| 20130091840 | SHOCKWAVE-ACTUATED POWER DEVICE - A shockwave-actuated power device includes a cylinder, a regulating module, and a piston assembly. The cylinder includes a chamber and a filling port in communication with the chamber. The regulating module includes first and second partitioning members and a driving member. The first and second partitioning members are received in the chamber, dividing the chamber into a high-pressure filling section, a shockwave train developing/actuating section, and a high-energy shockwave producing section located between the high-pressure filling section and the shockwave train developing/actuating section, with the filling port located in the high-pressure filling section. The driving member drives the first and second partitioning members to control communication between the high-pressure filling section, the high-energy shockwave producing section, and the shockwave train developing/actuating section. The piston assembly is movably received in the shockwave train developing/actuating section and drives a power output device. | 04-18-2013 |
| 20140165552 | PRESSURE WAVE GENERATOR WITH MOVABLE CONTROL ROD FOR GENERATING A PRESSURE WAVE IN A MEDIUM - Examples of a pressure wave generator configured to generate high energy pressure waves in a medium are disclosed. The pressure wave generator can include a movable piston with a guide through which a piston control rod can move or slide. The pressure wave generator can include a transducer coupled to a medium. During an impact of the piston on the transducer, the control rod can slide in the guide, which can reduce stress on the rod. The pressure wave generator can include a damper to decelerate the control rod, independently of the piston. Impact of the piston on the transducer transfers a portion of the piston's kinetic energy into the medium thereby generating pressure waves in the medium. A piston driving system may be used to provide precise and controlled launching or movement of the piston. Examples of methods of operating the pressure wave generator are disclosed. | 06-19-2014 |
| 20150020519 | Pulsed Plasma Engine and Method - Pulsed plasma engine and method in which a noncombustible gas is introduced into an explosion chamber, the gas is ionized to form a plasma within the chamber, an electrical pulse is applied to the plasma to heat the plasma, the pulse is turned off to produce an explosive pressure pulse in the plasma, and the plasma is confined in the chamber by a magnetic field that directs the pressure pulse toward an output member which is driven by the pressure pulse. | 01-22-2015 |
