  • Patent number: 10411580
    Abstract: An oscillator typically includes a rotatable drive shaft, at least two pivot members which rotate with the drive shaft, at least one oscillating member which is pivotable back and forth in an oscillating manner and at least one rod mounted on the at least one oscillating member which is movable in response to rotational and pivotal movement of the at least two pivot members so as to cause the oscillating member to pivot back and forth in an oscillating manner. At least one rotatable drive wheel may drive rotatable movement of the drive shaft. A drive mechanism may be used to drive rotation of the at least one drive wheel. At least one generating magnet may be mounted on the oscillating member and movable adjacent an electrically conductive coil for producing an electric current therein.

  • Patent number: 9564793
    Abstract: An oscillator typically includes several rotatable drive magnets and pivotable oscillating arms having respective follower magnets so that the drive magnets drive movement of the follower magnets to pivot the arms back and forth in an oscillating manner. A generating magnet or electrically conductive member may be mounted on each oscillating arm for producing an electric current in the electrically conductive member. Repelling magnets may be mounted on the oscillating arms with respective repelling magnets positioned to repel the first repelling magnet to limit pivotal travel of the oscillating arm.

  • Patent number: 7911096
    Abstract: An oscillator typically includes several pivotable oscillating arms each having a drive magnet and a follower magnet thereon so that the drive magnet on one arm drives movement of the follower magnet on another arm to oscillatingly pivot the other arm. Typically, a first repelling magnet is mounted on each oscillating arm and two repelling magnets are positioned on opposite sides of the first repelling magnet to facilitate the pivotal oscillation of the oscillating arm. A rotatable flywheel with a drive magnet thereon may drive movement of the follower magnet on one of the arms to drive pivotal movement of that arm. An electric motor may be used to drive rotation of the flywheel. A generating magnet may be mounted on each oscillating arm and movable adjacent an electrically conductive coil for producing an electric current therein. The coil may be in electrical communication with the motor.
