Abstract: A mechanical joint is provided comprising a bracket having a first elongated opening formed therein. An alignment guide comprising a second elongated opening formed therein is configured to rotatably attach to the bracket and is moveable between a first, floating position, and a second, non-floating position. In the first position the first elongated opening of the bracket and the second elongated opening of the alignment guide are axially aligned with one another and define a single elongated opening. In the second position the first elongated opening of the bracket and the second elongated opening of the alignment guide are partially aligned with one another and define a generally circular opening. The alignment guide is configured to slideably attach to a moveable end of a linear actuator.

Abstract: An electrical grounding strip has a first link and a second link, wherein the second link is connected directly to the first link, and each of the first and second links has a portion lying substantially in a plane and has at least one electrically conductive spike attached to the portion. The spike projects generally orthogonally to the plane of the link portion. An electrically conductive ground strap is in electrically conductive contact with the spikes of each of the first and second links.
