The invention modulates the air volume in foam cores of cushioning support devices and any other support apparatus using foam or similar materials. The foam core can be incrementally modulated to realize an infinite number of comfort levels as to softness and support firmness. The core consists of self-inflating open-cell flexible polyurethane foam and is completely sealed within an enclosure fitted over it, with one or more valves installed in the side walls which communicate with the outside air. Through the valves air is selectively withdrawn from the foam core, allowing the foam's density to increase. The invention uses relatively inexpensive foam, but through air volume modulation achieves a tactile feel of supreme softness for the user, without giving up the necessary firmness to support the body, as happens with very soft foam (bottoming-out or hammock-effect). When air is extracted from a self-inflating foam core, the surface of the core will soften uniformly while maintaining its support firmness. Contrary to this, when pressure is exerted on, for example, traditional coil spring core mattresses, their surface will harden. Integral part of the invention is a device using balanced springs in valve assemblies to avoid compression set, an irreversibly solid state of totally air-depleted foam.

The present invention comprises a concrete building system with a method for fabricating composite panels using an improved design plastic connector and assembling them at the construction site to a structure which will be shotcreted on both sides to a concrete building which is highly insulated, is fire and termite proof, hurricane, earthquake and flood resistant and fulfills the requirement for flexible design. The Composite Panels are composed of two concrete layers, enclosing an insulative foam core. The skins are reinforced with wire mesh as structurally required and are connected through the foam core by structural highly insulative plastic connectors using the snap connection on both ends of the connectors so they form a tri-dimentional system and hold the wire mesh in place for the onsite shotcrete application, which includes an application of fiber for shrinkage and cracking. This replaces the welded wire fabric use for secondly reinforcing and let the wire mesh reinforcing only related to the structural strength of the composite panel. The plastic connector guarantees that no thermal bridging occurs like in other systems also the inside layer of the shotcrete panel.

An insulating panel to be used in a panelized insulation system for insulating and finishing walls, including basement walls has a foam core made of inorganic materials. The system incorporates a capillary break, an integrated water drainage system and an electrical wire chase system within an insulating wall panel. Vertical slots are provided for insertion of metal studs for use in attaching the interior finish panel, such as inorganic fiber cement board with a vinyl laminate finish, onto the insulating panels. Embedding metal studs in the panel core reduces the sound transmission though the panel and eliminates thermal bridging between warm and cold surfaces. Steps on the edges and the top/bottom surfaces of the insulating panel allow more panels to join together with shiplap joints.

The EZ Laptop Stand® is a stand for a laptop computer that is very inexpensive, extremely lightweight, easy to assemble and disassemble and folds flat for portability. It is made from foamcore for its light weight, inexpensive material cost, and strength and durability when designed in the manner that it is. Manufacturing is done by laser cutting or die cutting, both methods being cost effective and practical for use with foamcore. There are three models of the EZ Laptop Stand®, the main feature of all three consisting of primary support members, which when folded or hinged at an acute angle at their mid point, create two strong triangular sloped surfaces tapered to a narrower dimension towards the bottom, front edge (the side closest to the user), where feet protrude upward for the laptop computer to rest against. These two primary support members are connected by two smaller cross-members that slide onto them along slots that keep all the pieces of the EZ Laptop Stand® fixed, in a rigid, upright formation on which the laptop computer rests. The EZ Laptop Stand® raises the laptop computer high enough to achieve proper ergonomics for the user while allowing comfortable use of onboard keyboard, high enough to allow adequate ventilation for heat dissipation from under the computer, high enough to provide protection from spilled of beverages, and is inexpensive to buy and simple to disassemble and reassemble for easy portability.

The EZ Laptop Stand® is made in 3 different designs called Model A, Model X, and Model U. Model A and Model X are for use on a desktop surface, under any laptop computer, but each one is designed to better accommodate slightly different configurations of laptop computers. Model U is for using a laptop computer while sitting or lying down when the user wishes to use it directly on their lap.
