A color display system has an image transforming device transforming an image signal of a XYZ colorimetric system to an image signal of a RGB colorimetric system and outputting the image signal of the RGB colorimetric system; and a display receiving the image signal of the RGB colorimetric system which has been output from the image transforming device. The bed rail is configured to be clamped to the mattress with a clamping force. The cable control clip is configured to be inserted through the cable to extend radially between the optical fibers and the jacket to limit contact between the optical fibers and one or more other components of the cable, and to limit displacement of the enclosure housing relative to the cable when the cable control clip is disposed in the chamber. The thermal catalysis body is made of tungsten, molybdenum, tantalum, titanium or vanadium, and is heated by a heater. A strain relief cable is also provided that connects to the output side, wherein the strain relief cable is configured to attach to the display and configured to ensure any output cables are not under tension.
