Abstract: A reflective surface electric road flare designed to be positioned on a roadway and to emit light to alert oncoming drivers to a hazard on the roadway. The flare comprises a housing supporting a circuit. The circuit comprises an led light source, a power controller and a power supply. The power controller energizes the led light source with the power supply such that the led light source emits light according to its design specification. The emitted light is concentrated about the horizontal by a lens into a horizontal light beam visible throughout the azimuth. Concentrating the emitted light into a horizontal light beam increases its intensity as perceived by oncoming drivers located within the projected horizontal light beam. A portion of the horizontal light beam intersects a top surface of the road flare where it is reflected towards oncoming vehicles.

Abstract: A solar-powered parking space barrier block is configured as a one-piece molded housing of a high strength, transparent plastic material in which a photovoltaic solar panel and a DC energy storage module are inclosed. A pair of white light LED lamps provide end panel marker illumination, two yellow light LED lamps provide hazard warning illumination and a rechargeable supercapacitor storage module provides operating power. A power control circuit enables use of the solar panel as a photosensor to automatically energize the LED lamps when ambient skylight falls below a predetermined safe visibility level, and removes operating power from the LED lamps when ambient skylight rises above a predetermined safe visibility level.
Abstract: A paving member (2) comprising a surface (4) for being walked on, an image (6) below the surface (4), and a source of light for illuminating the paving member (2), the paving member (2) being of such a material and construction that the image (6) is viewable by a person walking on the surface (4), and the source of light being such that it makes the image (6) visible at night and also provides light at night for the environment (8) adjacent the paving member (2). The image may be a static image or a moving image. The image may be a hologram. The image may be changed by remote control means.
Abstract: A chain-control device for solar road studs is provided to work by using a plurality of solar cells to convert solar energy into electric energy during daytime and store it in a battery unit, so that they can flash in nighttime for traffic security purpose or gardening deposition. The primary merit of the present invention is, first of all, free of wiring job, no need of city power, good conformity with environment protective conditions. Because of a successful chain control function, the existing random flash performance could be substituted with an interactive chain control flash or a synchronous flash performance, which is also applicable to gardening for fancy flash performance.

The inelastic is embodied in strands of material embedded in the carrier. Fastener elements extend through the strip for insertion into the roadway for strip retention.
Abstract: Retroreflective glass or plastic beads have fluorescent properties when irradiated with ultraviolet light and are emplaced in signs in patterns indicative of alphanumeric characters, or embedded in a hot melt comprising road stripes or embedded in the road asphalt or aggregate during construction of the road, to provide effectively bright and clear indications of signs or the extent and direction of the road. The glass beads comprise spherodized soda lime, borosilicate, phosphosilicate or aluminosilicate glasses with low levels of rare-earth dopants mixed therein, such as compounds containing one of the rare earths, or lanthanides. The plastic beads may have fluorescent materials mixed therein, typically organic pigments or dyes based on coumarin and rhodamine or the like.
Abstract: A method of making hot air in the range of 200 degrees (F) from the sunlight striking the paved surface of a parking lot is described. The transparent surface is above an opaque surface forming a homogeneous solid. Beneath the pavement are parallel pipes for the movement of air. The air is compressed into the pipe and sucked out of the pipes via photovoltaic powered fans. Due to the heat transfer through the walls of the pipes, ambient air is made hot. The hot air can then be used economically as precombustion air to a typical fossil fuel burner as oil, coal or gas. While the hot air would not be able to provide enough heat to power an entire power plant or oil refinery, the net result is more efficient fuel burning, with less air pollution produced, perhaps reducing fuel consumption by 5 to 10 percent. While the parking lot pavement may be made of recycled materials as glass or plastic, the pavement is still capable of supporting the weight of an automobile while also producing hot air.

A void or plate can separate the cables in a matrix of about 85 Shore hardness.

Abstract: Dynamic fountain displays and methods of creating the same for providing water displays wnich may substantially constantly vary in interesting and seemingly endless ways. In one form, the fountains are comprised of a matrix of fountain nozzles positioned below a deck formed with open joint paving so as to be useable as a patio or walkway when the fountain is not used. Each nozzle is connected to a source of water under pressure through a proportional control system for that nozzle responsive to a computer output so that each nozzle may be independently and proportionally controlled by the computer as desired. To facilitate the programming of the settings for a large array of nozzles, a plurality such as 256 individual patterns for the array of nozzles are first mutually programmed.
