  • Patent number: 7553049
    Abstract: A support arrangement is combined with a reflector sheet and fluorescent light tube to hold the reflector sheet above the tube in a curved trough shape maximum concentration of light at a desired distance from the light tube by varying the curvature in which the reflector sheet is held. An annular piece is detachable to form a larger opening to be fit to a larger tube, while an auxiliary strip can be mounted across the opening to create an opening for a smaller sized opening. The reflector sheet can be held in a reverse bent along its center to avoid light by the tube itself. Two clips can be mounted together at an adjustable distance from each other to allow mounting of a double sized reflector sheet over two side by side light tubes.

  • Patent number: 7510527
    Abstract: An illuminated display system and method of use may be applied to a variety of situations requiring organization, such as triage scenarios. Illustratively, illuminated signals from the illuminated display system visually provide the triage status of an injured user at a distance and in low-visibility settings. In particular, the illuminated display system includes a plurality of light emitters. Each light emitter from the plurality of light emitters provides a different predetermined wavelength of light than the other light emitters from the plurality of light emitters. In operation, each respective predetermined wavelength of light provides information relating to the degree of injury or other information associated with the user such that a desired light emitter is selected to display the desired wavelength and, ultimately, the desired information.
