ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to precessional devices, and particularly, to a device and method which utilize precessional forces in a controlled manner.
2. Background of the Invention
Precessional devices operate on the principle that a spinning mass, such as the rotor of a gyroscope, will resist any deflection of its rotational axis. If the rotational axis is deflected, Newton's Law of conservation of angular momentum dictates that the gyroscope will exert a precessional force at a right angle to the deflecting force. Precessional devices have performed a variety of functions in such diverse fields as navigational equipment and toys.
SUMMARY OF THE INVENTION
The present invention is briefly described as an apparatus and method of using precessional forces in a controlled manner.
In one aspect, the apparatus includes a first rotor spinning on a first spin axis and rotating around a rotational axis; and a second rotor spinning on a second spin axis and rotating around the rotational axis.
In another aspect, the apparatus includes a first rotor spinning on a first spin axis; a second rotor spinning on a second spin axis; the first rotor rotating inside a first track assembly; and the second rotor rotating inside a second track assembly.
In another aspect, the apparatus includes a first rotor spinning on a first spin axis; a second rotor spinning on a second spin axis; the first rotor rotating inside a first track assembly; the second rotor rotating inside a second track assembly; and wherein the first and second spin axes are located on substantially the same plane.
In another aspect, the apparatus includes a first rotor spinning on a first spin axis; the first rotor including first and second flywheels; and the first rotor rotating inside a support structure.
In another aspect, the apparatus includes a first rotor spinning on a first spin axis and rotating inside a first track assembly; and a second rotor spinning on the first spin axis.
In another aspect, the apparatus includes a first rotor spinning on a first spin axis; a second rotor spinning on a second spin axis; and a transmission operatively connected to said first and second rotors.
In another aspect, the apparatus includes a means for inputting a deflecting torque; and a means for substantially adding precessional torques about a first axis and substantially canceling precessional torques about a second axis.
In another aspect, the apparatus includes a first means for producing precessional torques along a first axis and a second axis; a second means for producing precessional torques along the first axis and the second axis; wherein the precessional torques substantially add along the first axis and substantially cancel along the second axis.
In another aspect, the apparatus includes a first means for producing precessional torques along a first axis and a second axis; a second means for producing precessional torques along the first axis and a second axis; and wherein the precessional torques create a variable resistance along said first axis.
In another aspect, the apparatus includes a first means for producing a plurality of precessional forces acting on a first track assembly; a second means for producing a plurality of precessional forces acting on a second track assembly; wherein said first and second track assemblies are connected to form a support structure; a plurality of handles mounted to the support structure; and wherein the precessional forces created by said first and second means create a variable resistance at the plurality of handles.
In another aspect, a method includes inputting a deflecting torque through a plurality of handles; and pulling and pushing against a variable resistance along one dimension.
In another aspect, the method includes rotating a first rotor around a rotational axis; and rotating a second rotor around said rotational axis in an opposite direction.
In another aspect, the method includes rotating a first rotor around a track assembly; rotating a second rotor around a second track assembly attached to the first track assembly; and creating a variable resistance along one dimension.
In another aspect, the method includes rotating a first spin axle containing a plurality of flywheels around a first track assembly; rotating a second spin axle containing a plurality of flywheels around a second track assembly in an opposite direction; and outputting a variable resistance along a first axis and substantially canceling forces acting along a second axis.
In another aspect, the method includes turning a hand crank to input a first deflecting torque to a first rotor rotating in a first direction and a second deflecting torque to a second rotor rotating in a second direction within a support structure; and grasping handles attached to said support structure and inputting a third deflecting torque against a variable resistance provided by the first and second rotors.
