Abstract: This invention relates to the field of personnel access control and more particularly, to deployable/stowable fabric-based barriers for controlling or restricting access of individuals to specific physical areas. This allows security personnel at a screening station, for example, to quickly react to an “intruder” who is bypassing the screening area by quickly and safely closing the passageway and/or walkways between a screening area and a sterile area. Recognizing that different facilities and different applications place more emphasis on some design requirements than others, three barrier systems were designed to increase overall suitability for different facilities: Drop Down BCBS, Pop Across BCBS, and Pop Up BCBC.

Abstract: The present invention provides a blast-resistant panel and container to protect objects against the blast force from an explosive device. The invention consists of a first layer whose shape and/or size may be altered by the blast force without substantial release of gases therethrough, a compressible second layer, and a third layer. When absorbing a blast, the first layer moves toward the third layer thereby compressing the second layer, the second layer absorbs the blast energy, and the third layer prevents substantial displacement of the second layer. In the preferred embodiment, the first layer is constructed of overlapping plates which can slide relative to one another. In another embodiment, the first layer is constructed of axially-slidable plates, the movement of such plates being guided by guiding ribs.
