A system for supplementing the electric power needed by a pump jack electric motor, thereby reducing the electric power purchased from the local utility or power supplier. The system comprises a solar photovoltaic system, or other forms of renewable energy, and regenerated power from the electric motor or drive. The system can be both on-grid and off-grid. Battery banks and capacitor banks may be used to store energy.

A method for supplying vacuum for a pneumatic brake booster for a motor vehicle braking system, using an electromotively-driven displacement type pump assembly. At least one pressure sensor for monitoring a pneumatic pressure is associated with the pump assembly, and electric signals of the pressure sensor are fed to an electronic unit, analyzed, and processed in order to regulate the pressure. A plausibility check of the pressure sensor signal is carried out by a pressure value amplitude being determined, by signal analysis, in the form of a difference between a maximum pressure value and a minimum pressure value within a stroke of the displacement element, and this being compared to a stored comparison value wherein if the pressure value amplitude deviates from the comparison value by a defined amount, the signal of the pressure sensor is then defined as implausible.

A device for driving an ancillary unit of an internal combustion engine includes the ancillary unit having a mechanical drive, joined to a first coupling section, and an electric drive having a rotor and a stator with windings. The rotor is joined to a second coupling section and non-rotatably to a shaft. The shaft is joined to a component of the ancillary unit to be driven. The rotor is movable axially along a lengthwise extension of the shaft and axially with respect to the shaft. The first and second coupling sections are movable relative to each other by means of the axial movement of the rotor so as to either join together or separate the mechanical drive and the rotor, the rotor being movable axially along the lengthwise extension of the shaft with respect to the shaft in such a way that an electric current flows through the windings.

A storm dissipation system having: means for moving water from a body of water located in the proximity of said storm, and means for mixing said water with the air for the purpose of changing the energy of said storm.

The present invention concerns itself with systems and methods for the dissipation of hurricanes and/or tropical storms through the use of wind turbine pumps. These pumps, which are driven by the storm's own winds, draw cold deeper water from below the storm and spray it high into the air. This cold spray absorbs the heat energy from the air thus removing the driving force (the heat energy) from the hurricane. The spray also acts as a brake on wind speed. Hence, by using a series of these wind turbine pumps acting in cohesion, dissipation of hurricanes and/or tropical storms may be achieved.

A wave energy absorption device comprises a buoy adapted to move with movements of water, and a buoy oscillation device attached to the buoy, the buoy oscillation device comprising an elongated means and a rotary means adapted to interact with the elongated means. A hydraulic pump with variable displacement is connected to the rotary means and connectable to a hydraulic circuit. When the buoy moves with movements of water, relative movement is created between the elongated means and the rotary means, whereby the hydraulic pump transforms kinetic energy into hydraulic energy which to the hydraulic hose, and whereby a torque is applied to the rotary means by the hydraulic pump to dampen or amplify the movements of the buoy. The buoy oscillation device provides individual control of the force applied to the buoy by change of displacement in the hydraulic pump.
