Abstract

In one embodiment, a ball turret assembly for supporting a camera includes a first shaft rotatable about a first axis relative to a first fixed point, the first shaft having an axially-extending interior region in communication with an exterior of the first shaft by way of a first exit port. A first guide disposed at least partially circumferentially on the first shaft proximally to the first exit port is provided, and a cable extends along the interior region of the first shaft and exits the first shaft at the first exit port, the cable looping at least partially around the first shaft and affixed at the first fixed point.

Claims

1. A ball turret assembly for supporting a camera, comprising:

a first shaft rotatable about a first axis relative to a first fixed point, the first shaft having an axially-extending interior region in communication with an exterior of the first shaft by way of a first exit port;

a first guide disposed at least partially circumferentially on the first shaft proximally to the first exit port; and

a cable extending along the interior region of the first shaft and exiting the first shaft at the first exit port, the cable looping at least partially around the first shaft and affixed at the first fixed point.

2. The ball turret assembly of claim 1, wherein rotation of the first shaft imparts roll motion to the camera.

3. The ball turret assembly of claim 4, further including a fairing into which the first shaft extends, the first fixed point being fixed relative to the fairing.

4. The ball turret assembly of claim 1, wherein the first shaft is configured to rotate less that 360 degrees.

5. The ball turret assembly of claim 1, wherein the first shaft is configured to rotate about 270 degrees.

6. The ball turret assembly of claim 1, wherein rotation of the first shaft imparts tilt motion to the camera.

7. The ball turret assembly of claim 6, further including a ball turret housing the camera, the first shaft being rotatable relative to the ball turret, the first fixed point being fixed relative to the ball turret.

8. The ball turret assembly of claim 6, wherein the first shaft is configured to rotate less than 135 degrees.

9. The ball turret assembly of claim 1, further comprising:

a second shaft rotatable about a second axis relative to a second fixed point, the second shaft having an axially-extending interior region in communication with an exterior of the second shaft by way of a second exit port; and

a second guide disposed at least partially circumferentially on the second shaft proximally to the second exit port,

wherein the cable extends along the interior region of the second shaft and exits the second shaft at the second exit port, the cable looping at least partially around the second shaft and affixed at the second fixed point.

10. The ball turret assembly of claim 9, further comprising a yoke supporting one of the shafts, the cable passing along an interior portion of the yoke.
