Abstract: Using a programmable aerial drone assembly configured to actuate a gearbox that repositions one or more solar panels, automated drones may be deployed to adjust the position of the solar panels throughout the day according to a programmable schedule. In exemplary embodiments, a plurality of docking stations may be deployed throughout a solar farm, such that one or more solar panels are mechanically coupled to the docking station, wherein the docking station includes a landing platform and a gearbox mechanically configured to adjust the position of the solar panels. One or more gearbox arms protrude from the top of the docking station landing platform, and corresponding arms on the aerial drone assembly engage the gearbox arms to actuate the gearbox. The aerial drone assembly also includes landing posts that register with the docking station.

Abstract: A mine car coupling assembly comprising a spring biased receiving assembly having a pair of jaw members mounted about a pivot point. The forward ends of the jaw members are beveled and tapered inwardly to form a hook configuration adapted to receive and hold an arrowhead shaped male member. Each jaw member's forward end is biased toward the other jaw member's forward end by a spring assembly mounted to both of the jaw members. The tip of the arrowhead member initially engages the jaw members of the receiving assembly and overcomes the spring assembly's force, forcing the jaw members apart. When the arrowhead has entered into the receiving assembly the hook ends are urged back toward each other by the spring assembly to engage the rear surface of the arrowhead member and hold the arrowhead member in position within the receiving assembly.

Abstract: A combined docking and grasping device for use with a manipulator arm on a docking vehicle and the like for mechanically connecting a docking vehicle with an orbital payload having a receptacle for receiving the device therein.The device includes a pair of opposing jaw members having opposing serrated surfaces for grasping an object and a triangular cam portion on an outer surface for insertion and interlocking with an orbital payload.
