Patent ID: 7051608

Claim:
Gyroscopic actuator, used to produce a torque or momentum on a platform on which said gyroscopic actuator is located comprising: a torque mechanism to deliver torque to the platform at a constant value or a mean value with a cyclic disturbance of less than 20% of the mean value, when a torque vector has a fixed direction in an inertia reference system, wherein the torque has a duration unlimited unless the parameters that produce the torque are intentionally changed, in which case the torque mechanism carries out, one or more of the following: (a) stop delivering torque, (b) increase or decrease the value of the torque, or (c) change the torque vector direction wherein said torque mechanism is comprised of at least two pair of rings placed concentrically, each pair of rings act by spin rotation and coordinated in nutation rotation to produce torque.
