Abstract: A mount system is described. An exemplary embodiment is a device that provides rotary damping to a mounted device, e.g. a camera system, when mounted to a moving arm. As the arm changes attitude, the mount system allows dampened rotary movement of the mounted device about an axis, due to gravity forces.

Abstract: A positioner system is provided with one or more slip clutch assemblies. A slip clutch may include a torque adjustment mechanism for adjusting a slip torque parameter. A sensor system may be included to re-establish reference positions due to clutch slippage, or monitor absolute and/or incremental position of the head. An energy commutator system may be provided to pass energy through the slip clutch assembly.
