A vane support system includes a frame and a vane. The invention allows for such operative features to come into direct contact with body structures, such as the inner wall of a lumen. An absorber having a heat absorbing tube and a heat absorbing shoe is supported from the mirror such that the tube is positioned coaxially along the focus line to receive reflected sun light. According to some embodiments, the network circuits are each assigned a priority, and the coexistence controller can control operations between the network circuits by selectively adjusting one or more transmission operating parameters of a respective network circuit based on a plurality of operating criteria, which include each network circuit’s priority.
