Abstract: Systems, methods and apparatus are provided for angulation enhancement. An X-ray system comprising X-ray detector and X-ray source disposed at different ends of the X-ray system. An apparatus shifts a beam field produced by the X-ray source towards the edge of the X-ray detector whereby a large X-ray detector on a vascular X-ray system can be utilized to image smaller anatomy at extremes angles.

Abstract: A scaffolding plank includes a frame, a plank secured atop the frame, and hook members secured to the frame at a respective corner thereof. The frame includes a first longitudinal support, a second longitudinal support, and a third longitudinal support disposed between the first longitudinal support and the second longitudinal support. The frame further includes a first end support secured at first ends of the first, second, and third longitudinal supports and a second end support secured at second ends of the first, second, and third longitudinal supports. The frame still further includes a first center support secured between the first and third longitudinal supports offset from the midpoint of the frame and a second center support secured between the second and third longitudinal supports offset from the midpoint of the frame.

Abstract: An apparatus and method for construction of scaffold structures having improved safety characteristics. In various embodiments, the apparatuses comprise a set of structures, including connecting rails, fencing, gates, and ladders. The structures are adapted to be used with locking-cup type scaffold designs. In one embodiment, the apparatus comprises a scaffold joint comprising a vertical post comprising first and second joint sections. At least one structural brace is disposed within the joint sections having a mounting flange disposed at an angle to the principal axis of the structural brace.

Abstract: In certain embodiments, the improved safety ladder and harness assembly described herein incorporates a harness coupling designed to slide freely within the vertical member of a safety ladder so long as the forces exerted on the coupling are small. Any significant external force applied to the coupling, such as the application of a worker's weight, will result in a braking and holding action by the coupling until the external force or weight is removed. In one embodiment, the apparatus incorporates a substantially cylindrical coupling body having a braking lever extending from the front side, an upper braking nub extending from the upper portion of the coupling body in the same direction as the braking lever, and a lower braking nub extending from the lower portion of coupling body in the opposite direction as the braking lever.
