Abstract: This invention relates to devices for converting a small input force to a larger output force and particularly relates to devices and methods for converting an input force to an output force comprising: an arm rotatable about an axis of rotation where the axis of rotation is moveable between first and second positions; an input force for rotating and moving the arm about the axis of rotation between the first and second positions; structure for controlling the rotation of the arm, movement and position of the axis of rotation to generate a non-circular orbital segment of the arm to transfer an output force between the first and second positions.

Abstract: A torque multiplier for converting an input torque to an output torque. A torque multiplier includes a cam mounted on a drive shaft for rotation therewith when an input torque is applied to the drive shaft, the cam providing a magnetic field that is radially asymmetrical relative to the drive shaft, a first output shaft for providing an output torque, and a magnet spaced apart from the cam and mounted to move relative to the cam in response to magnetic coupling forces between the cam and the magnet as the cam rotates, the magnet being operatively connected to drive the first output shaft, wherein magnetic coupling forces between the cam and the magnet return rotational energy to the drive shaft during part of the cam rotation.
