System for optimal energy harvesting and storage from an electromechanical transducer

A device for collection of energy from mechanical disturbances and distribution of that energy to an electrical load. A transducer converts mechanical energy in the form of forces and displacements into electrical energy in the form of charge pulses. The charge pulses are rectified into a Direct Current (DC) power signal and accumulated and stored in an input storage element. A controlled conversion circuit assures that the voltage on the storage element is maintained within a predetermined optimal range for energy harvesting from the transducer, avoiding the application of peak voltages. The controlled conversion circuit can be hard wired and / or controllably adjustable to match a given disturbance characteristic. Only when the voltage is within the optimal range for a given type of disturbance will the controlled conversion circuit enable a DC / DC converter to further convert the stored energy to a voltage that is coupled to an output storage element. This technique optimizes power conversion by controlling the high voltage to low version conversion process by, for example, sensing the disturbance with external sensor or internal voltage of the system, and then using this information about the disturbance to control how and when the electrical conversion process will occur.

Wind turbine generator and motor

A wind turbine includes a quartet of pivot shafts that are in paired parallel relationship and transversely mounted on a central drive shaft. each pivot shaft supports a pair of wings at opposed ends thereof, the wings offset by 90°. Each pivot shaft rotates cyclically through 90° to move each wing from a wind-engaging orientation (drive position) in which the wing presents a flat surface approximately transverse to the incident wind, to a minimum drag position (glide position). In addition, the two wings of each pair on a shaft are disposed in planes that are offset by approximately 90° about their pivot shaft, so that one is in the drive position while the other is in the glide position. The wings of each pair of pivot shafts have wings at the ends thereof that open into the drive position at the same time and rotational angle of the turbine. A backstop at the site of each drive position supports the wind load and transfers its force to the central drive shaft.

Superconducting switch operation

A method of operating a superconducting switch system to protect against quenching in a superconducting magnet circuit is provided. The system comprises a magnet circuit, a main superconducting switch and an auxiliary superconducting switch connected in parallel thereto by low resistance connecting parts. In an initial magnet energisation procedure, after establishing superconducting flow in the circuit, the main and auxiliary switches are closed to cause current to persist in the circuit without further power input. If the main switch quenches, the current will transfer to the auxiliary switch through the resistive connecting parts. Upon restoring the main switch to the superconducting state, the voltage drop through the resistive connecting parts will drive the current back through the main switch. A preconditioning procedure is carried out as part of the magnet energisation procedure to ensure that opening the main switch will establish superconducting current through the auxiliary switch.

Joints among individual entrance conveyors, among individual exit conveyors, and among conveyors are likewise elastic constructions by means of adjustable screws placed between fixed cantilevers, and between tension cantilevers. It is further enabled by the construction of entrance units and exit units in the flow press, or by the construction of pushing wheel pairs inside them, and which are simultaneously driven by the central driving coupling. For this purpose, each wheel pair is equipped with a pair of flexible cranks, the cylinder for pressure adjustment, the cylinder for position adjustment, the mechanism for interactive distance adjustment.
