The camera support for cinematography equipment has end blocks and side beams forming a perimeter frame with an open central area. The approach includes a method that includes receiving transmitted data with a buffer. A first transistor of the at least two transistors is located at a first end of the at least two transistors. The second flow meter includes a second measuring tube. A top mirror may be disposed above the discrete light source to convert modes of light emitted from the discrete light source into trapped modes, thereby increasing the coupling efficiency of the illumination structure.
