HANDHELD OR VEHICLE-MOUNTED PLATFORM STABILIZATION SYSTEM
First Claim
1. A hand-held stabilization system comprising:
- a base;
a stabilized platform includinga first frame rotatably coupled to the base on a first pivot axis, includinga first actuator disposed to torque the first frame about the first pivot axis responsive to a first motor signal, anda first rotational sensor having a rotation-sensitive sensor axis and producing a first sensor signal representing the rotation of the first frame with respect to the base; and
a second frame rotatably coupled to the first frame on a second pivot axis, includinga second actuator disposed to torque the second frame about the second pivot axis responsive to a first motor signal, anda second rotational sensor having a rotation-sensitive sensor axis and producing a second sensor signal representing the rotation of the second frame with respect to the first frame;
at least one handle adapted for grasping by a human operator to facilitate moving the hand-held stabilization system about during operation; and
a controller for producing each of the motor signal plurality responsive to a respective one of the sensor signal plurality, whereby the stabilized platform is disposed in a predetermined position independent of the position of the base.

Abstract
A hand-held or vehicle-mounted stabilization system including a platform supported by two or more rotatably-coupled gimbal frames each having a pivot assembly disposed at its rotation axis to couple an actuator to a rotation sensor having a rotation-sensitive sensor axis that is preferably fixedly disposed with respect to the rotation axis, and a controller for accepting the sensor signals and for producing each motor signal needed to dispose the platform in a predetermined angular position with respect to each rotation axis independent of changes in mount orientation. An alternative embodiment includes a controller for accepting an external slew signal sequence and for producing the motor signals needed to move the platform along a predetermined sequence of positions represented by the slew signal sequence.
