Abstract
A precessional device having independent control of the output torque generated by the device and the oscillation rate of the device is disclosed. The device comprises a rotor supported by an axle wherein the ends of the axle are supported by a circular race. The circular race is rotatable, and may be driven by a motor or other means, thereby controlling the oscillation rate of the device independently of the output torque arising from the rotation rate of the rotor. The motor may be controlled by a control program that adjusts the rotation rate of the circular race to modify the shape of the resistance curve.
Claims7
An apparatus comprising:
- a track with a circular shape;
- an upper continuous surface coupled to the track;
- a lower continuous surface coupled to the track;
- and
- a rotor that spins about a spin axis and rotates about a rotational axis, wherein the rotor includes an axle with axle tips that are substantially aligned with the spin axis of the rotor, wherein the axle tips and the continuous surfaces cooperate in the following two modes:
- a first mode such that a spin rate of the rotor about the spin axis and a rotation rate of the rotor about the rotational axis are dependent upon each other;
- and
- a second mode such that the spin rate of the rotor about the spin axis and the rotation rate of the rotor about the rotational axis are independent of each other.
