The linear module contains a direct drive linear machine for converting linear mechanical motion into electrical energy. The linear module may be used between any two oscillating mechanical bodies, exploiting their relative motion, and adapting to the mechanical characteristics of the larger system in which it is deployed.

A power generator includes a box-shaped body having an inner chamber containing a first gyroscopic device comprising that includes a first frame hinged to the body around a first axis, a first gyroscope being carried by the first frame in a rotatable manner around a second axis perpendicular to the first axis, a first actuator being carried by the first frame to rotate the first gyroscope around the second axis, and a first converter device that converts of rotational mechanical energy into electric energy that is mechanically coupled to said the first frame. The first converter device is connected to a stabilizing device. A second gyroscopic device includes a second frame hinged to the body around a third axis transversal to the first axis.

The present invention relates to the utilization of wave energy and its conversion into operating motion of an electrical energy generating system. The system for generation of electrical energy through the conversion of aquatic wave motion includes floating bodies and a constant rotation mechanism, which converts the two-way linear motion of an inflexible transmission shaft or a flexible transmission shafts into one-way rotation of an output shaft of the constant rotation mechanism. This mechanism allows utilization of wave energy in two directions caused by the rise and fall of waves. The output shaft of the constant rotation mechanism is coupled to a force multiplier that is further coupled to a generator which generates electrical energy. Constant rotation mechanism can be driven by inflexible transmission shaft pivotally coupled to the floating bodies at one end, and the other end to an input gear of the constant rotation mechanism. Depending on the height of the wave and the wavelength, various constructions of floating bodies are used. Certain floating bodies are designed for the waves of a smaller amplitude and smaller wavelength, while other floating bodies are designed for bigger amplitude and bigger wavelength.

The invention relates to a method and a system for adjusting the torque of a mass and spinning wheel rotator in a wave power plant. The torque of a rotator rotating around a vertical shaft is compensated partially or completely with a compensating moment which is produced by an electric machine. Acceleration components (.sup.ACCx and .sup.ACCy) are measured for a given point of the wave power plant's floating body (1) in directions perpendicular to each other. A vector (V.sub.xy) with a magnitude formula (A) and a direction (a.sub.Acc) is established for said acceleration components, the direction or angular position (a) of a rotator (2) is monitored and its lag (α.sub.LAG) from the acceleration vector's direction (α.sub.Acc) is determined. The compensating moment is adjusted as dependent on a compensation factor (B) whose sub-factors are the magnitude of the body's acceleration vector (V.sub.xy) and the sine of the angle of lag (sin α.sub.LAG). This is supplemented with a compensation factor based on spinning wheel forces in a manner otherwise similar except that the acceleration must be replaced with a rotation speed (AV.sub.x-y) of the body's inclination, which is obtained from an inertial sensor 821). and the mass must be replaced with a gyro force which is dependent on the inertia and rotating speed of a spinning wheel.

A hinge system and method for an Articulated Wave Energy Conversion System (AWECS) that provides for hinge and piston pump displacements due to multi-axis forces in allowing adjacent barges of the AWECS to pivot with respect to one another due to wave motion. The hinge system uses a plurality of parallel hinges, and axle segments, coupled between adjacent barges wherein the hinges are coupled to upright trusses positioned transversely along facing edges of each barge. Hinge bracing includes lower V-shaped struts that act as lower stops when the barges pitch up and also include upper struts that act as upper stops when the barges pitch down. The pumps are positioned in parallel. The pumps have special couplings such as ball joint couplings that permit motions other than longitudinal pump/ram motions due to multi-axis forces generated by the wave motion and thus provide omni-directional stress relief to the pumps.
