  • Patent number: 10050511
    Abstract: A magnetic coupling device for communicating continuous rotational or linear motion through a magnetic coupling of magnetic forces communicated from magnets operatively positioned on an oscillation assembly and a rotation assembly in positions sufficiently proximate to form the magnetic coupling. Employed to communicate an output force in a rotational direction from an input linear force communicated from a powered oscillation assembly, the magnetic force of the magnet communicating the force compresses the volume of ellipsoidal-like magnetic fields of the coupling alternately in unlike polar domains, to induce a smooth, blended polar continuity and communicate a continuous 360 degree rotational force to a rotation assembly operatively engaged with the magnetic coupling. The input force may be reversed to induce a continuous linear motion of a reciprocating assembly.

  • Patent number: 9843248
    Abstract: An extended duration burst electrical energy harvesting generator in one embodiment including two magnets situated on opposite ends of an angular movable lever with a centered fulcrum support in an angular displacement (see-saw) arrangement. The two magnets are under the bi-stable magnetic attractive influence of dual magnetic metal (high permeability) substrates that are disposed at a distance within two separate center core electric coil bobbin forms that are situated under the opposite ends of the lever. Either one of the magnets, in time, will make or break contact with one of the substrates producing an instantaneous induced voltage at each of the coil terminals. The two induced voltages can be utilized to power battery-less and wireless remote communications control function such as ISM Band wireless transmitters and battery-less electronic device applications.
