Abstract: An Emergency Vehicle Warning Indication system is provided. Disclosed herein are systems and methods for providing notification of emergency vehicles in advance of the approaching intersection further comprising one or more Control Modules or Modular Transmitters that receive and transmit a high secured radio frequency. This secured radio frequency may be further configured such that it is used only by Emergency Vehicles. The system and method further comprising a means for overriding the traffic signal sequence of the traffic signal system at the intersection. The system and method further comprising an emergency lighting system. Wherein the emergency lighting system may operate in conjunction with at least one of the traffic signal system, the emergency vehicle, and one or more Control Modules or Modular Transmitters.

Abstract: A non-flammable ternary liquid cleaner is formulated from a first solvent that is a dichloroethylene, a second solvent that is a hydrofluorocarbon and a third solvent that is a fluoroketone having low flammability. The dichloroethylene is present in a concentration of at about 50 percent to about 60 percent by weight of the cleaner, the hydrofluorocarbon is present in a concentration of about 25 percent to about 35 percent by weight of the cleaner and the fluoroketone is present in a concentration of at about 13 percent to about 25 percent by weight of the cleaner.

Abstract: A demiseable momentum exchange system includes a base and a flywheel rotatably supported on the base. The flywheel includes a web portion defining a plurality of web openings and a rim portion. The momentum exchange system further includes a motor for driving the flywheel and a cover for engaging the base to substantially enclose the flywheel. The system may also include components having a melting temperature below 1500 degrees Celsius. The momentum exchange system is configured to demise on reentry.

Abstract: A head mounted lens support for performing examination and photography of the posterior structures of the eye. The support includes a lateral support to which a pair of adjustable earpieces, and an adjustable nosebridge are attached. Right and left lens positioners are moveably and pivotable attached to the lateral support. The lens positioners each are adjustable by lateral positioners, depth positioners, and angle positioners. The angle positioners swivel from their nominal positions, perpendicular to the lateral support, through an arc of approximately 25 degrees in order to allow full examination of the structures in the posterior chamber of the eye. Right and left lens cradles are attached, respectively, to the ends of the right and left angle positioners. The lens cradles are forms of arc clamps which receive a lens sleeve. The lens sleeve is itself an arc clamp which contains the actual lens.
