An impact shield for earthquake protection is described herein. The impact shield may include a canopy constructed of a puncture-resistant material, the canopy defining a first internal volume accessible via a first opening, the canopy being structured to form a semispherical shape when in an inflated state, the semispherical shape defining a space dimensioned for sheltering at least one human body; a support joined to the canopy and constructed of the puncture-resistant material, the support defining a second internal volume accessible via the first opening and a second opening, the support located within the space, the support structured to form a column when in the inflated state; and a fitting joined to the support for closing the second opening to fix the first internal volume and the second internal volume after inflation of the support and the canopy.

Disclosed are the design and utilitarian characteristics of a support device for supporting a cover wherein such cover is typically used to cover a vehicle such as a boat or automobile. The invention includes a dome shaped support device with a depending base configured for extending through a cover. The depending base defines an interface for being associated with a support structure such as a pole and such interface may be a swivel interface. Additionally, the support device may define a suspension interface so that a tether may be used to apply a support force from above the support device. The support device may also define a swivel device configured for being associated with a support surface such as a floor.

A tent system including a first tent section having a first transition border. The first transition border is configured to receive a first support member at a first transition height. The first transition border has a first transition width. A first transition section is defined by the first transition border and a second transition border. The second transition border is configured to receive a second support member at a second transition height. The second transition border has a second transition width that is less than the first transition width. A flexible roof is configured to cover the first tent section and the first transition section. The flexible roof is configured to be supported by at least the first support member and second support member. The flexible roof is configured to cover the tent system.

A method of installing a releasable shade membrane to a shade system is presented. The method comprises installing a tension release system within a structural component of the shade system. The tension release system comprises a threaded member configured to, when actuated, cause a coupling mechanism to move along an axis defined by the threaded member. The method also comprises coupling a shade membrane to the coupling mechanism. The method also comprises actuating the threaded member in a first direction, such that the coupling mechanism moves along the axis in a tensioning direction. The tension release system is configured to release applied tension upon actuation of the threaded member in a second direction, causing the coupling mechanism to move along the axis in a release direction. The release direction is substantially the reverse direction of the tensioning direction.

A temporary maintenance enclosure for the maintenance of at least part of a turbine blade, the enclosure comprises a platform arranged, in use, to border at least part of the circumference of a blade in need of maintenance; at least one wall and a roof which are carried by the platform; the at least one wall extending from the platform; wherein said roof extends from the wall towards the blade; and wherein the enclosure further comprises a flexible sheath which seals onto the blade to provide a sealed volume for maintenance of said blade.
