Abstract: A suspension arm assembly includes at least three horizontally aligned members relatively rotatable about each other, each adjacent pair of the at least three horizontally aligned members being connected to each other by a joint; a conduit pathway for positioning at least one conduit such that the at least one conduit extends along the at least three horizontally aligned members, outward of a load bearing periphery of the at least three horizontally aligned members; a brake system comprising a brake at each joint for selectively preventing movement of respective adjacent ones of the at least three horizontally aligned members about the joint; and at least one shell arranged about the at least three horizontally aligned members and the conduit pathway.

Abstract: A gripping assembly for gripping at least one conduit routed within a vertically adjustable medical boom head assembly includes a support, and a plurality of grip paddles pivotally mounted to the support and arranged around a central pathway for routing the at least one conduit, wherein the grip paddles are configured to pivot inwardly relative to the central pathway to grip the at least one conduit running through the central pathway.

Abstract: A suspension arm assembly including at least three horizontally aligned members relatively rotatable about each other. Each adjacent pair of members are connected to each other by a joint. At least one conduit extends along the at least three horizontally aligned members, with the at least one conduit being routed horizontally along the horizontally aligned members and not being located within a periphery of the at least three horizontally aligned members.

Abstract: A medical device assembly including a movable suspension arm, a vertically adjustable service head located at an end of the suspension arm, the vertically adjustable service head including a service head face with outlets thereon, and conduits routed by the suspension arm, into the vertically adjustable service head in a horizontal direction and vertically within the vertically adjustable service head to the outlets. The vertically adjustable service head includes a vertically adjustable column for raising and lowering the outlets.

Abstract: A medical suspension arm assembly including a plurality of suspension arms, with each adjacent pair of the suspension arms being connected to each other by a joint and with at least one of the joints comprising an infinite rotation joint. The infinite rotation joint allows the suspension arms at the infinite rotation joint to have unlimited rotation relative to one another. Cabling including at least one fiber optic cable extends through each of the suspension arms and each joint. A wired medical unit is connected to an end of the plurality of suspension arms. High definition video, data and power can be transferred along each one of the suspension arms through the cabling and across each joint.

Abstract: A Fresnel lens including a plurality of sawtooth-shaped projections, with each projection including a first surface at a first angle and a second surface at a second angle. Each first surface has top and bottom edges and each second surface has top and bottom edges. Each projection has a top intersection where the top edge of the first surface intersects the top edge of the second surface. Adjacent projections have a bottom intersection where the bottom edge of the second surface of a first one of the adjacent projections intersects the bottom edge of the first surface of a second one of the adjacent projections. The lens portion is opaque at the top intersection of the projections, at the bottom intersection of adjacent projections, and on the first surface between the top intersection and the bottom intersection.
