Patent Images
1. A camera head comprising:
- a first frame;
a first arm rotatably attached to the first frame;
a first motor for rotating the first arm relative to the first frame, with the first motor enclosed within a sealed first housing;
a second frame attached to the first arm;
a second arm rotatably attached to the second frame;
a second motor for rotating the second arm relative to the second frame, with the second motor enclosed within a sealed second housing;
a first shaft rotatably supported within the first housing, with the second frame attached to the first shaft, and the first shaft sealed against the first housing, a first gear linked to the first shaft through a first clutch, and with the first gear linked to the first motor, and one or more clutch drive pins sealed against the first housing, and moveable from a first position, wherein the first motor drives the first shaft through the first clutch, to a second position, wherein the first shaft can rotate free of the motor.

Abstract
A remote camera head has a tilt frame attachable to a pan frame at multiple positions. A roll frame is attachable to the tilt frame at multiple positions. The camera head can be expanded or reduced in size as needed based on the space requirements of the camera and camera accessories mounted on the camera head. Waterproof or sealed slip ring assemblies and connectors allow the camera head to operate in wet environments, or even when submerged in water. The camera head can be quickly installed, set up, balanced, or reconfigured.

7. A camera support comprising:
-
a first housing having a first interior sealed space; a first purge gas port on the first housing connecting into the first interior sealed space, for delivering a purge gas into the first interior sealed space; a first motor supported by the first housing; a second housing having a second interior sealed space, and with the second housing linked to the first motor for rotational movement of the second housing relative to the first housing about a first axis; a second motor supported by the second housing; a second purge gas port on the second housing connecting into the second interior sealed space, for delivering a purge gas into the second interior sealed space; a third housing linked to the second motor for rotational movement of the third housing relative to the second housing about a second axis substantially perpendicular to the first axis; and a lock pin moveable between a lock position, where the lock pin extends between the first housing and the second housing, to prevent movement between them, and an unlock position, wherein the lock pin is withdrawn from one of the first and second housings, to allow rotational movement between them. - View Dependent Claims (8, 9)
