A novel, high-efficiency, extremely light-weight, inflatable refractive solar concentrator for space power is described. It consists of a flexible Fresnel lens, flexible sides, and a back surface, together enclosing a volume of space which can be filled with low pressure gas to deploy the concentrator on orbit. The back surface supports the energy receiver/converter located in the focal region of the Fresnel lens. The back surface can also serve as the waste heat radiator. Prior to deployment, the deflated flexible lens and sides are folded against the back surface to form a flat, low-volume package for efficient launch into space. The inflatable concentrator can be configured to provide either a line focus or a point focus of sunlight. The new inflatable concentrator approach will provide significant advantages over the prior art in two different space power areas: photovoltaic concentrator arrays and high-temperature solar thermal conversion systems. Photovoltaic concentrator arrays using the new inflatable lens will be much lighter than prior space concentrator arrays. In addition, for photovoltaic concentrator arrays, the new inflatable lens will eliminate the need for a fragile glass superstrate to support the lens, substantially improving robustness of the lens. Solar thermal concentrator arrays using the new inflatable lens will be much lighter than prior art space concentrators which used parabolic mirrors. In addition, for solar thermal applications in space, the new inflatable lens will eliminate the need for high surface accuracy, which has been a significant problem for prior art concentrators.

A method and system for installing an insulated concrete wall includes insulation panels placed in an upright manner. Generally T-shaped wall studs are placed next to the insulation panels such that the front section of the wall stud is on the outside of the insulation panels and an anchoring section of the wall stud extends beyond the insulation panels into the gap into which concrete will later be poured. Concrete pouring forms are placed so as to render the gap into which concrete will be poured a desired thickness. The wall stud may also include slots for receiving cross-ties that secure the concrete pouring forms in proper position and retaining nubs that prevent the insulation panels from floating when concrete is poured. Concrete is then poured into the gap, surrounding the anchoring section the T-shaped wall stud.

A safety system for a truck loading dock with an elevated platform provides an alarm that warns of a hazard at the loading dock such as a forklift operating inside the truck or a falling hazard that may exist due to the dock door being open while a truck is not present at the dock. In cases where a dock's open doorway is protected by a barrier that can be opened or closed, the alarm can be de-activated by closing the barrier. In some embodiments, the safety system includes a remote body sensor that detects when someone or something is near the doorway. In response to the body sensor, a second, more pronounced alarm can warn of more imminent danger where someone on the platform may be too close to an open doorway when a truck is not present.

A panel for forming a masonry wall on a building surface, comprising a back face for covering the building surface, opposite edges and a front face with a predetermined pattern of first and second depressions. The first depressions are shaped and sized for receiving masonry pieces as a whole whereas the second depressions, which intersect the opposite edges, are shaped and sized for receiving parts of masonry pieces, so that, when the panel is mounted side by side with a complementary panel, some masonry pieces bridge both panels by means of the second depressions. The panel makes it possible for an unskilled worker to build relatively rapidly a masonry work having a complex predetermined pattern of masonry pieces. Thanks to the second depressions that make it possible for some pieces of masonry to bridge panels mounted side by side, the general arrangement of pieces, when completed does not look like a series of individual panels but rather look continuous.

This is an improved method of building with fibrous material though other materials can be substituted. A binding secures fibrous material to form a wall assembly (10). Wall surfacing (20) can be included in the binding and forming process, reducing the labor required to apply it. Other building features and components can also be included in the binding and forming process such as electrical wiring, furring strips, windows, doors and structural reinforcing. This method vastly reduces the difficulties encountered when installing these components. The versatility of the method also allows for attributes such as flat wall surfaces and variable wall thicknesses, which are difficult to achieve using baled fiber.
