An inflatable air mattress for preventing snow accumulation is provided. The mattress comprises an inflatable portion comprising a textile material, and an outside air intake. A fan draws outside air into the inflatable portion through the air intake, and circulates the air when inflated. An air divider alternates between an inflating position and a circulating position that determines which air the fan blows. An air heater heats the air that passes through the fan. A controller activates the fan and air heater based on a signal from a snow sensor; controls the divider based on a signal from a pressure sensor; and controls the heater based on a signal from a heat sensor.

An air dome foundation comprises multiple foundation modules (110). The multiple foundation modules (110) are used to be placed on the ground end to end. The foundation modules (110) comprise straight structure and L-shaped structure. The foundation is low in construction cost, short in construction period and suitable for always moving or the situation in which original ground surface can not be modified or damaged.

A portable shelter with low emissivity is provided for sheltering materials or human occupants at a remote location. The shelter has a flexible, multi-layer cover, including a vinyl material, reflective material located inside and immediately adjacent to the vinyl material, and insulation material located inside the reflective material. The low- vinyl cover is lightweight and thermally efficient. The shelter may be adapted for use with interior-climate control equipment at the remote location.

A portable structure including a solar shade is disclosed. The portable structure includes a frame comprising at least two beams, a main panel extending between the at least two beams, and a solar shade. The solar shade includes at least one solar shade panel spaced above the main panel by at least one inflatable beam to create a space between the solar shade panel and the main panel. The space creates an insulative layer to help regulate an interior temperature of the portable structure.

An inflatable wall material, including: a thermal insulation layer, a first metal layer, a barrier layer, a buffer layer, a protective layer, and a second metal layer. The first metal layer, the barrier layer, the buffer layer, the protective layer, and the second metal layer are arranged on two sides of the thermal insulation layer in sequence from the inside to the outside. The two barrier layers on the two sides of the thermal insulation layer employ air-tight materials. The two barrier layers and the first metal layers on the two sides of the thermal insulation layer constitute an inflatable air-tight space. The thermal insulation layer is positioned in the air-tight space.

A building cover element is described with at least one, preferably stationary arranged fastening device, which comprises an exterior section aligned to the exterior of a building to be provided with the building cover element, comprising at least one film element, which shows an exterior film layer to be arranged at the exterior of the building and anchored with an edge section at the fastening device, and with at least one thermally insulating element. The thermally insulating element is arranged with a first section at the exterior section of the fastening device and with at least one second section resting on the edge section of the exterior film layer of at least one film element.

An exemplary controlled environment greenhouse may include an inner membrane defining an interior space and having at least one opening. The greenhouse may also include an outer membrane arranged outside of the inner membrane to define an air gap therebetween. The greenhouse may further include at least one fan configured to draw air from within the interior space through the at least one opening into the air gap, and recirculate the drawn air back into the interior space. The greenhouse may further include at least one heat exchanger configured to enable heat transfer between the drawn air and a heat transfer medium. The greenhouse may have a dome-shaped or arcuate cross-section.

Transportable and rapidly deployable air supported structure systems and related methods are disclosed. The air supported structure systems include at least one transportable container. The systems also include a flexible outer membrane configured to couple to a base in a substantially air-tight manner. The systems further include at least one air handling mechanism contained within the at least one container configured to force air between the outer membrane and the base to form an enclosure therebetween via internal air pressure. The systems are configurable between a packaged state with the outer membrane contained within the at least one container, and a deployed state with the outer membrane being coupled to the base and the at least one air handling mechanism forming the enclosure via the internal air pressure. The at least one container may form a portion of the base and/or provide for ingress and egress with the enclosure.

A portable structure including a solar shade is disclosed. The portable structure includes a frame comprising at least two beams, a main panel extending between the at least two beams, and a solar shade. The solar shade includes at least one solar shade panel spaced above the main panel by at least one inflatable beam to create a space between the solar shade panel and the main panel. The space creates an insulative layer to help regulate an interior temperature of the portable structure.

An airform that can be inflated, for example, for facilitating construction of a structure is provided. The airform may include a first portion, a second portion, or multiple other portions, and reinforcement. The first portion may, for example, be configured to be disposed in a first orientation, such as vertically or in a radial profile, when the airform is inflated. The second portion transitioning from the first portion may be configured, for example, to assume an alternate shape and profile, such as a radial shape and profile, when the airform is inflated. The reinforcement may, for example, be provided at a portion of the airform that defines a transition from the first portion to the second portion.
