    摘要: An traffic light capable of utilizing both natural sunlight and artificial light for illuminating selective traffic signals. Natural light is directed to a natural light router or switch and to a color switch for providing a red, amber or yellow, and a green light for each bank of traffic light signals. A controller is coupled to the natural light router and light emitting diodes for controlling the mode of operation for operating the traffic light with either electrically powered light emitting diodes or with natural light collected by the natural light collector. A sensor detects the adequacy of the natural light, and when insufficient, causes the controller to power an LED signal light. The natural light may either be amplitude modulated or time modulated so as to provide a desired high illumination output to the desired signal light. The power consumption is greatly reduced, as well as providing a more reliable traffic light substantially independent of power line interruptions or fluctuations. Any information, not only traffic signals, may be displayed.

    摘要: A technique for manufacturing durable, reliable solar cells by a continuous process suitable for large-scale manufacture involves, in substance, providing a reel of thin metal foil substrate and forming on the substrate a series of layers operative to form a photovoltaic junction, short prevention blocking layers, contacts and integral encapsulation. The foil substrate is processed as a continuous reel substantially until final testing at which point, if desired, it can be cut into individual cells for deployment. In comparison with a batch process, the continuous technique can reduce manufacturing cost by as much as a factor of two.

An inlet manifold is in fluid communication with an inlet valve of the second cylinder. A bypass valve is in fluid communication with the second cylinder and the inlet manifold, wherein during a compression stroke the bypass valve allows a portion of the air to bypass the inlet valve and exhaust into the inlet manifold to provide a variable compression ratio.

    摘要: Composite material composed of conducting and semi-conducting oxide partis, fibers, or flakes suspended in a of polymeric material matrix for use in connectors, junction boxes, enclosures or similar electromagnetic shielding applications. The use of a composite material with electromagnetic shielding properties built into the material itself, combined with the use of a semi-conductive filler that minimizes the corrosive effect of an electrochemical potential difference, provides EM shielding and corrosion resistance for these materials when they are used in marine and aircraft environments. Oxide semiconductor materials and compatible conductive fillers also provides a basis for a new class of EMI and EMP composite materials that exhibit a stable current-controlled and voltage-controlled negative resistance (VCNR, CCNR) characteristic. Testing has shown that the conductivities of these materials increase as the field and/or the voltage increases. This characteristic is desirable, providing inherent protection of electronic circuits from voltages or currents. This VCNR/CCNR effect is dependent upon the voltages, the degree of filler material combinations and the filler loading which will determine the composite materials properties.

    摘要: A method of improving the electromagnetic (EM) shielding performance of a mposite material is provided. The composite material has conductive and semi-conductive filler particles suspended in a non-conductive resin. The filler particles can be up to 40 weight percent of the composite material. The composite material is electroplated with a conductive material onto a portion of its surface to improve the electrical connection between the conductive material and a portion of the filler particles.

In a preferred embodiment, the absorber is a layer of copper sulfide and the composite layer comprises a thin layer of copper oxide formed on the copper sulfide and a layer of encapsulating glass formed on the oxide. It is anticipated that such devices, when exposed to normal operating conditions of various terrestrial applications, can be maintained at energy conversion efficiencies greater than one-half the original conversion efficiency for periods as long as thirty years.
