Abstract: A magnetic braking system for inhibiting excessive motion between a float (5) and a column (3) intended to be placed in a body of water; with the float (5) and column (3) moving relative to each other as a function of the waves present in the body of water. The braking system includes a permanent magnet assembly (PMA) mounted on, and attached to, one of the float (5) and column (3) and a coil assembly (or conductive plate) mounted on, and attached to, the other one of the float (5) and column (3). The braking system is mounted such that motion between the float (5) and column (3) is inhibited when the displacement of the float (5) relative to the column (3) exceeds a predetermined operating range.

Abstract: For the purpose of converting the mechanical energy of surface waves on bodies of water, a power generating piezoelectric structure (10) is provided comprising piezoelectric material members, preferably in the form of one or a laminate of sheets (14) of such material, each sheet having an electrode (24) on opposite surfaces thereof. Each pair of electrodes and the piezoelectric material therebetween define a power generating element, each of which is preferably dimensioned, relative to the wave lengths of selected waves on the body of water in which the generator is to be used, for increasing the efficiency of power conversion. A support (12) is provided for maintaining the structure in a preselected position within and below the surface of the water. Preferably, the pizoelectric generating elements are flexible and are supported in such manner to allow flexure thereof in response to movement of the surrounding water. In certain embodiments the elements are designed to enter into mechanical resonance in response to the passage of waves thereover, such flexure and/or resonance increasing the mechanical coupling efficiency between the waves and the elements.

Abstract: An ocean wave energy converter (WEC) utilizes the relative motion between permanent magnet(22) and induction coil assemblies(24) to generate electricity. The permanent magnet assemblies(22) and induction coil assemblies(24) are separately housed in watertight enclosures, enabling a wide range of wave energy converter configurations, nearly unlimited stroke and obviating the need for a common magnet/coil enclosure with seals. The magnet assemblies(22) are constructed with surface or buried magnets. The wave motion moves a magnet assembly relative to a stationary coil assembly, or vice versa. Either the magnet assembly(22) or the induction coil assembly(24) are made long enough to provide the generation of electricity over a desired operational range of travel. Various means are provided to maintain the spacing ("gap") between the magnetic(22) and coil assemblies(24) relatively constant.
