Abstract: Rotary support systems, associated control devices, and methods of operating the same. Rotary support systems include a mast configured to support an elevated device and a base that includes a rotary mechanism that rotatably couples the mast to the base. The rotary mechanism is configured to selectively rotate the mast. The mast has a cross-sectional profile that is non-circular. Rotary support systems additionally may include a controller configured to interface with an electric motor to rotate the mast with respect to the base. Controller implemented methods for operating a rotary support system include receiving an input command and, responsive to the receiving the input command, sending an output command to an electric motor to rotate the mast relative to the base.

Abstract: An improved corner guard for use on a pre-hung door assembly. The corner guard of the present invention is designed for use with a pre-hung door assembly that includes a door secured within a three-sided door frame in which the two vertical frame members extend in an offset manner below the bottom edge of the pre-hung door. In a preferred embodiment, the corner guard includes a bumper member for imposing a gap between adjacent stacked assemblies. A substantially flat transition flange member is attached to one end of the base of the bumper member, and together, the transition flange member and bumper member base form a retention barrier surface across the front corner region of the pre-hung door assembly to maintain the door securely seated within the door frame. A fixed side flange is affixed to the other end of the bumper member and extends approximately perpendicularly with respect to the bumper member base surface such that a right angle inner surface corner contour is formed therebetween.
