  • Patent number: 9329458
    Abstract: A pan/tilt head that can be used with a camera is disclosed that includes a tilt range extender. The pan/tilt head has a main housing formed from a central housing and two housing sides. A pantograph linkage is connected to a housing side. The pantograph linkage includes an upper transverse member and a lower transverse member. The lower transverse member is connected to the housing side at a non-rotating mount on the tilt axis. The upper transverse member is connected to the tilt range extender. The tilt range extender rotates about the tilt axis.

  • Publication number: 20120263446
    Abstract: An apparatus for controlling one or more cameras is provided. The apparatus includes: a mounting sled, a tilt drive motor, a tilt drive train, a pan drive motor, and a pan drive train. The mounting sled includes a camera platform between two sled runners. A lower surface of each sled runner is formed by a circular arc. The tilt drive train includes a tilt drive shaft having an axis perpendicular to the camera platform. The pan drive train includes a pan drive shaft extending along the axis of the tilt drive shaft such that it receives the tilt drive shaft and turns independently and concentrically about the tilt drive shaft. The camera platform receives a camera such that the center of gravity of the camera is aligned with the diameter of the circular arc of the sled runners and the vertical axis of the tilt and pan drive shafts.
