Abstract: The pneumatic structural element comprises from one to a number of interconnected elements of the following construction: two hollow bodies made of textile material coated in a gas-type manner and each having two end caps are assembled such that they produce a common sectional area. The edging of this sectional area is formed by two curved tension/compression elements into which is clamped a gas-tight web made of a flexible material of high tensile strength. This web can be connected to the tension/compression elements in a gas-tight manner. By filling the two hollow bodies with compressed gas, a tensile stress ? pretensions said web. This pretensioning increases the bending rigidity of the tension/compression elements. If a plurality of such elements are combined to form a roof, every two adjacent hollow bodies thus form a sectional area with a tension/compression element and web.

Abstract: Work crews temporarily operating in remote areas can be subject to dangers such as tornadoes, hurricanes and explosive blast waves. A re-deployable aboveground protective shelter suitable for use in such environments utilizes retractable stabilizing arms and/or passive valved ductwork to resist uplift, overturning and sliding. Because the protective shelter does not rely upon excessive weight to counter wind forces, the protective shelter can be quickly, easily and inexpensively redeployed to new sites.

When deployed, the inflatable structure is of substantially increased interior volume. In one embodiment, access between the interior of the first module and the second module is provided by at least one port or structural pass-through. In another embodiment, the inflatable structure includes at least one additional generally toroidal module external of and circumferentially surrounding the second module.

A cover encloses the inflatable pool and the floating holding pillow. An outer edge of the cover is attached to an outer edge of the mat whereby the water and inflatable pool are completely enclosed, so that the floating pillow pushes up on the inside of the cover, thereby the cover is formed into a convex shape so that rainwater is shed from the convexly-shaped cover.

Abstract: A joint element for a pneumatic structural element. The joint element includes a sleeve, a compression member, two tension members and two spherical caps. In each case one joint element is fitted for the spherical caps. The joint elements serve for introducing tensile and compressive forces, in a manner free of bending moments, into the pneumatic structural element. The joint element has holes for fastening the compression member with a screw, on the one hand, and holes for accommodating the tension members, on the other hand. The symmetrical arrangement of the holes ensures that the vectors of bearing forces and of the tensile and compressive forces in the joint element added together give zero and, furthermore, the bending moments occur symmetrically in relation to the compression members. Configuring the joint element as a plate ensures that torques are neither introduced from the outside nor diverted to the outside.

Abstract: Barriers and methods of obstructing apertures. One embodiment provides a temporary barrier that includes a bag, a fluid source, and a shear thickening fluid. The bag is made of fabric and can expand (e.g. inflate) via the fluid source which is in communication with the bag. The shear thickening fluid permeates the fabric of the bag and has two states. In the first state the shear thickening fluid allows the fabric to be flexible. In the second state the shear thickening fluid causes the fabric to be inflexible. To cause the shear thickening fluid to transition to the second state a shear must be present in the shear thickening fluid. A material that is capable of reacting to form a gas may be in communication with the fluid source to provide a gas to expand the bag. A deflation valve may also be included in the barrier.
