    摘要： A motorized pan/tilt head and support member for mounting a video camera or the like. A pan/tilt head is mounted upon a first end of the support member. This head is substantially U-shaped, with a bottom cross member and parallel legs at opposite ends of the cross member. The video camera or the like is pivotally suspended between the two legs. Electric motors housed within the cross member and legs, provide panning and tilting motion through the use of gear mechanisms attached to the motors. In order to provide closed loop control, position sensing devices are driven by each of the motors to provide an output signal related to position. The electrical wires of the components pass along the central axis of the support member and terminate at an electrical plug at the second end thereof. This plug mates with a second portion affixed to a surface to which the support member is to be releasably attached. The entire unit is made to be liquid proof, and all components are remotely replaceable. In preferred embodiments, high intensity lights are moved in unison with the video camera. In one embodiment a "crash plate" with limit switches are provided to stop motion of the pan/tilt head if an object is encountered. The unit is principally for use in harardous areas such as those where radioactivity is present.

    摘要翻译： 电动摇摄/倾斜头和用于安装摄像机等的支撑构件。 摇摄/倾斜头安装在支撑构件的第一端上。 该头部基本上为U形，底部横向构件并且在横向构件的相对端处具有平行腿部。 摄像机等可枢转地悬挂在两条腿之间。 容纳在横梁和腿部内的电动马达通过使用连接到马达的齿轮机构来提供摇摄和倾斜运动。 为了提供闭环控制，位置感测装置由每个电机驱动以提供与位置相关的输出信号。 组件的电线沿着支撑构件的中心轴线延伸，并在其第二端处终止于电插头。 该插头与固定到支撑构件可释放地附接到的表面的第二部分配合。 整个单元被制成防液体，所有组件都可远程更换。 在优选实施例中，高强度光与摄像机一致地移动。 在一个实施例中，提供了具有限位开关的“碰撞板”，以在遇到物体时停止摇摄/倾斜头的运动。 该单位主要用于诸如那些放射性存在的地区。
