Abstract: A linear generator includes a permanent magnet array having at least two magnets arranged end-to-end. A set of conductive coils is arranged around the permanent magnet array. A four-phase full wave rectifier is configured to accept alternating current inputs from the set of conductive coils and to produce one or more direct current outputs. A summing circuit is configured to aggregate the one or more direct current outputs from the rectifier to produce a combined, rectified direct current output.

Abstract: A spring suspension system includes a top spring assembly connected to a top end of a stator and a top end of a cable and a bottom spring assembly connected to a bottom end of the stator and a bottom end of the cable. The top spring assembly includes a central spring connected to the top end of the cable at a bottom end of the central spring and a set of symmetrically arranged springs, each connected to the top end of the stator and to a top end of the central spring, configured to accommodate torsional and rotational components of an input force.

Abstract: Various embodiments of permanent magnetic arrays are disclosed. Such arrays include a central support tube; permanent magnets arranged along the central support tube, where the permanent magnets are oriented such that like poles of the magnets are placed adjacently to concentrate a magnetic field in a direction perpendicular to an axis of the central support tube; and pole pieces arranged along the central support tube, each pole piece in contact with two neighboring permanent magnets and separating those two neighboring permanent magnets.

Abstract: An energy converter system includes a rotor and a stator configured to be relatively stationary with respect to an environment. One of the rotor and the stator includes a field coil array and braking magnets, while the other of said rotor and said stator includes a permanent magnetic array that is configured to induce an electrical current in the field coil array in response to relative motion of the rotor and the stator. Magnets in the permanent magnetic array are oriented such that like poles of the magnets are disposed adjacently to concentrate a magnetic field through the field coil array. The braking magnets are oriented such that poles of the braking magnets face like poles of the closest respective magnet in the permanent magnetic array.

Abstract: Various embodiments of linear electric generators and arrangements thereof are disclosed. One such generator includes a permanent magnetic array with magnets that are oriented such that like poles of the magnets are disposed adjacently to concentrate a magnetic field through a coil array. To enhance the magnetic field distribution, the magnets are affixed under a compressive strain due to repulsive forces resulting from proximity of the like poles. According to another aspect, a plurality of vibrational linear electric generators (VLEGs) can be arranged so that magnets of different VLEGs are oriented so that poles of opposite polarity are disposed adjacently to further enhance magnetic field concentration through coil arrays. In addition, a plurality of wave energy converters can be arranged in very close proximity, at most 8 times a height of a buoyant portion of the converters, to act as a seawall and thereby protect various structures from ocean waves.
