Abstract: An access floor panel that includes a base and a top plate on top of the base in a thickness direction of the access floor panel. The base includes at least one elongated slot having (1) a depth in the thickness direction, (2) a longitudinal axis in a first direction perpendicular to the thickness direction and (3) a slot opening in the top of the base in the thickness direction. The top plate has an elongated opening that is aligned with the slot opening of the at least one slot. The base and the top plate are configured such that a fastener assembly is received through the slot opening of the base and the elongated opening of top plate and retained within the slot to attach a structure to the access floor panel.

Abstract: A secure video visitation booth configured for individual use. The booth includes a plurality of wall assemblies joined at edges to form the walls of the booth, a mesh ceiling panel supported by the wall assemblies, a bench, an A/V module in one of the wall assemblies, a door in a door opening in another of the wall assemblies and a window in yet another of the wall assemblies. Each of the wall assemblies is of a spaced double wall construction, with an acoustic insulation material between the two walls.

Abstract: An upper portion of an aisle containment system for a data center. The upper portion includes spaced vertical supports aligned in two parallel rows and horizontal supports that extend between and are connected to adjacent vertical supports to form the basic framework of the upper portion. The upper portion also includes (1) at least one pair of arms that extend outwardly from opposite longitudinal sides of the basic framework and are configured to support services and (2) at least one busbar casement that is attached to the vertical supports and extends substantially the length of the upper portion. Each arm of the at least one pair of arms includes a segment that is rotatable between a first position in which the segment is substantially parallel to the vertical supports and a second position in which the segment is substantially perpendicular to the vertical supports.
