Precise parameters are maintained in a support system for solar panels or other panel-like structures through use of a collapsible folding, support frame which is preassembled to precise tolerances at a convenient staging site before being collapsed for shipment. Installation on flat roofs is also facilitated through the use of a roof interface frame which rotatably supports the panel support frame of the support system and folds along with it at the assembly, staging site.

The invention provides methods, systems, and devices for installing thermal barriers in openings or gaps in or between structures such as walls, ceilings, and floors. At least one thermal barrier molding bag is positioned in the hole or gap, and a flowable firestop material that is operative to cure or harden, such as a hydratable cementitious slurry, is introduced into the bag to mold a barrier in the hole or gap.

A color balancing circuit for a flat panel display such as an electroluminescent display generates a primary current that can be varied to adjust the overall brightness of the display. Three currents related to the primary current by selectable ratios are generated, by current mirror circuits, for example; the ratios can be individually varied to adjust the color balance. Driving currents are generated from the three adjusted currents, by mirroring the adjusted currents, for example, and are used to drive display elements that emit light in the three primary colors. Image brightness and color balance can accordingly be adjusted separately, even though both are adjusted by adjusting the driving current. Circuit size is reduced in that the same primary current is used for all three primary colors.

A sandwich beam including in one example first and second spaced walls, a core configured to maintain a predetermined spacing between the walls when the core is filled with pressurized gas and to resist shear when the beam is loaded in bending and a port for filling the core with gas biasing both walls in tension. The tension tends to increase in the second wall and decrease and cause a compression load in the first wall in response to a sufficiently large applied bending load. A compression element is fixed only with respect to the first wall and is configured (a) to support the compression load so that the beam is stronger at a given gas pressure and (b) to flex sufficiently to allow the beam to be rolled up when the gas is emptied from the core via the port.

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.

The present invention relates to an improved wall system where a wall form mold has a structural insulated core assembled to form a structural insulated panel (SIP) to form a concrete beam and concrete column to be poured anywhere within the wall as well as between building modules when placed together and erected vertically. The interlocking wall molds interlock within the wall as well as between panels and modules. The wall panels allow concrete columns and beams to be formed with an ICF in any size and shape. The structural insulated core consists of interlocking foam spacers and support channels which can be glued or screwed together to form an independent wall or as part of a precast wall with columns and beams integrated within the wall panels. Expanded and insulating flanges within the wall forming mold separates the wall forming structure from the wall surfaces.

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.

The plastic concrete is then formed into a desired shape having a top and sides. A second layer of insulating material is placed on the top of the plastic concrete and the first and second layers of insulating material are left in place until the concrete is at least partially cured. The second layer of insulating material is then removed. The product made by the method is also disclosed. A slab on grade is also disclosed.

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.

Methods and apparatus providing a column forming assembly formable from multiple column forming sub-assemblies that are stackable providing a compact storage or transport configuration. A column forming structure is formed from multiple elongated wall sections configured for interlocking engagement with each other to form a hollow, open ended structure adapted to accept a settable substance, such as concrete or plaster. The multiple elongated wall sections are stackable and can be stored to shipped to a job site in a condensed or nested configuration. The nested configuration reduces empty or hollow spaces provided by assembled forms. In some embodiments, the forms can be disassembled after use for transport from the jobsite, storage, and later reuse. The column forming assembly can be combined with one or more column-end forms and with thin-walled column forming inserts.
