Abstract: An adjustable height system that provides an automatic manner of height adjustment for a platform. The platform is supported by a frame including a scissor lift assembly which raises and lowers the platform to any desirable height. The height is adjusted by activating a portable drive device which is engaged with an adapter element that couples a gearbox to a threaded drive member that actuates the scissor lift assembly. Using the portable drive device in forward or reverse, the platform is respectively raised and lowered.

Abstract: A system comprises a set piece, a threaded block, and a nut and is configured to support a panel in a railing system. The set piece comprises a block portion and a base portion. The block portion has a first planar surface and an opposing, second planar surface. The base portion is planar and extends from an edge of the block portion substantially perpendicular to the first and second surfaces of the block portion and away from the first surface of the block portion. The threaded block comprises a base and an extended circular portion. The circular portion comprises a threaded surface on the circumference, and the threaded block is configured to align with the set piece. The nut is configured to engage the threaded block. The nut comprises a corresponding threaded internal circular surface to rotatably engage the extended circular portion and move orthogonal to the threaded block base.

Abstract: An acoustic shell system includes a frame comprising a first column, a second column, and a base. The first and second columns each comprise a circular portion with a channel along the length of the column where the circular portion is configured to attach to one or more panels. The circular portion is coupled to a noncircular portion opposite the channel having at least one channel along the length of the column and configured to attach to one or more components. The base comprises first and second arms coupled to opposing ends of a cross-support. Each of the arms is also coupled to one of the columns at about a ninety degree angle. The length of the cross-support is less than the distance between the first and second columns.

Abstract: A wall transport device comprises a base, a plurality of wheels positioned below the base, a steering assembly attached to the base, and a wall support pivotally connected to the base. The wall support includes a telescoping mast, a top hook, and a bottom flange. A first mechanism tilts the wall support between a proximal and a distal position. A second mechanism raises and lowers the top hook.
