Abstract

A stabilizing controller to balance, support and orient a device. The stabilizing controller includes a gimbal assembly positioned at the center of balance of the stabilizing controller with the device attached. A handle is disposed around the gimbal assembly. A center post is coincident with at least a portion of the centerline of the gimbal apparatus and has a longitudinal balancing axis Z. Motion about at least one of the mutually perpendicular X-axis, Y-axis, and the Z-axis is isolated from the motion of the other axes via one or more assemblies, including a magnetic braking assembly.

Claims

1. A stabilizing controller to balance, support and orient a device, the stabilizing controller comprising:

a gimbal assembly positioned at the center of balance of the stabilizing controller with the device attached;

a handle disposed around the gimbal assembly;

a center post coincident with the centerline balancing axis of the gimbal apparatus and having a longitudinal balancing axis Z, the center post attached such that motion about each of an X-axis, Y-axis, and the Z-axis, the three of which are mutually perpendicular to one another, is isolated from the motion of the other axes; and

a magnetic braking mechanism to control rotational motion about the X-axis and Y-axis.

2. The stabilizing controller of claim 1 wherein the magnetic braking mechanism comprises:

a magnet positioned at the bottom of a gimbaled center post;

a handle disposed around the center post and the magnet;

a non-conducting component disposed beneath the magnet a distance sufficient to induce eddy currents capable of dampening the motion of the center post.

3. The stabilizing controller of claim 1 further comprising a mechanism to control motion about the Z-axis.

4. The stabilizing controller of claim 3 wherein the mechanism is a button, which when depressed engages a component to arrest motion of the center post in about the Z-axis.

5. The stabilizing controller of claim 3 wherein the mechanism is a slot in the handle through which the center post can be engaged by an operator.

6. The stabilizing controller of claim 3 wherein the mechanism is a magnetic braking system.

7. The stabilizing controller of claim 1 further comprising an additional dampening mechanism to control rotational motion about at least one of the X-axis, Y-axis and Z-axes.

8. The stabilizing controller of claim 7 wherein the additional dampening mechanism includes one or more resilient components disposed along an interior surface of the handle to control motion of the center post against the handle.

9. The stabilizing controller of claim 7 wherein the additional dampening mechanism controls rotational motion about the Z-axis and comprises:

a resilient component having a first end and a second end;

the resilient component first end attached to a pan shaft and the resilient component second end attached to a gimbal shaft.

10. The stabilizing controller of claim 7 wherein the additional dampening mechanism controls motion about the Z-axis and comprises one or more springs wherein a first end of each spring is connected to the handle and the second end of each spring is connected to an outer gimbal ring.

11. A method of balancing and stabilizing a device comprising:

attaching a device to a stabilizing controller according to claim 1.

12. A stabilizing controller comprising:

a holder to accommodate an image-capture device;

a stage attached to the holder at its bottom portion;

one or more balancing arms pivotable with respect to the stage and disposed in an open position in substantially the same plane as the holder, and pivotable within that plane;

a gimbal apparatus with a handle according to claim 1 attached to the stage.

13. The stabilizing controller of claim 1 configured for use with an image-capture device weighing in the range of about 0.2 lbs to about 1.5 lbs.

14. The stabilizing controller of claim 13 further comprising the device.

15. The stabilizing controller of claim 14 wherein the device is an imaging device.

16. The stabilizing controller of claim 2 wherein the non-conducting component is moveable with respect to the handle in a slidable motion, a tilting motion or a combination of thereof.

17. The stabilizing controller of claim 1 wherein motion about the Z-axis about the center post is controlled by an assembly having:

a pan shaft disposed coincident with at least a portion of the longitudinal centerline of the handle;

a gimbal shaft disposed coincident with at least a portion of the longitudinal centerline of the handle;

a resilient strip having a first end and a second end, the first end attached to the pan shaft; and

the second end attached the gimbal shaft.

18. The stabilizing controller of claim 1 wherein the assembly to control rotational motion about the Z-axis includes:

a resilient component having a first end and a second end;

the resilient component first end attached to a pan shaft and the resilient component second end attached to a gimbal shaft.

19. The stabilizing controller of claim 1 wherein motion about the Z-axis about the center post is controlled by an assembly having one or more springs wherein a first end of each spring is connected to the handle and the second end of each spring is connected to an outer gimbal ring.

20. The stabilizing controller of claim 1 wherein rotational motion about the Z-axis about the center post is controlled by an assembly having one or more paddles extending radially with respect to the center post, and one or more resilient pads into which the paddles come into contact when the handle is rotated about the longitudinal axis of the center post.

21. The stabilizing controller of claim 1 wherein rotational motion about the Z-axis about the center post is controlled by an assembly having:

a pad ring non-rotationally attached to an outer gimbal ring;

one or more paddles attached to the pad ring and extending radially outward from the pad ring;

one or more pads formed of a resilient material attached to the handle and disposed between the paddles, with gaps between the paddles and the pads, such that when the handle is rotated with respect to the outer gimbal ring, the pads contact the paddles, thereby controlling the rotational motion about the Z-axis.

22. The stabilizing controller of claim 1 further comprising counterweight(s) disposed about the center post to position the center of balance of the device and stabilizing controller below the pivot center of a the gimbal assembly.

23. A stabilizing controller to balance, support and orient a device, the stabilizing controller comprising:

a gimbal assembly positioned at the center of balance of the stabilizing controller with the device attached, the gimbal assembly having concentric rings including an inner ring, middle ring and outer ring, each pivotably attached to its adjacent ring;

a handle disposed around the gimbal assembly;

a center post coincident with the centerline balancing axis of the gimbal apparatus and having a longitudinal balancing axis Z, the center post attached such that motion about each of an X-axis, Y-axis, and the Z-axis, the three of which are mutually perpendicular to one another, is isolated from the motion of the other axes; and

one or more inner resilient components attaching the inner ring to the middle ring;

one or more outer resilient components attaching the middle ring to the outer ring.

24. The stabilizing controller of claim 23 wherein the resilient components are attached at the pivot points of the adjacent rings.

25. The stabilizing controller of claim 23 further comprising one or more additional resilient components to control motion of the center post when the outer gimbal ring is tilted from a plane perpendicular to the center post.
