    摘要： The present invention concerns a security barrier for providing protection in a public space or the like, said barrier comprising a mineral wool assembly comprising at least one mineral wool element having an outer liquid impermeable covering and wherein the at least one mineral wool element is adapted for being filled with a liquid. The invention further comprises a method of manufacturing such security barrier and a method of preparing the security barrier for providing protection in a public space.

    摘要： A housing arrangement comprising a housing an inner space for accommodating components capable of forming sources of ignition. The housing arrangement further comprises a partial housing arranged in or on the housing and the interior space. The interior space acts as a pressure relief volume. The interior space and the pressure relief volume are connected together via a passage in which a gas-permeable and flame-arresting arrangement is provided. This can be formed from a porous body, for instance, which is gas permeable and acts in a throttling and cooling manner on a gas flow passing through it.

    摘要： A shielding system includes a plurality of transportable modules, wall panels, or pods that are connectable to form a containment area and to define a radiation barrier. Each of the plurality of transportable modules has a first radiation wall defining the containment area, a second radiation wall spaced apart from the second wall, and a radiation shielding fill material positioned between the first radiation shielding wall and the second radiation shielding wall. The radiation shielding fill material includes one of a superabsorbent polymer (SAP) filling a portion of a void between the first radiation wall and the second radiation wall, or a non-Newtonian fluid completely filling the void between the first radiation wall and the second radiation wall. A quantity of the radiation shielding fill material is sufficient to substantially reduce measurable radiation level outside the containment area.

    摘要： A defense mobile device for securing a door during shelter-in-place situations. The device includes wheels rendering it mobile and stops that, when activated, hold the device stationary. A panel has a ballistic core that resists bullets, a front face, an opening, and a cover positioned over the opening to overlay and enclose a door knob protruding through the opening. The front face forms, or has affixed to it, a writing surface. The panel pivots between a plurality of angled positions to facilitate writing and an upright position flat against the door. A locking rod, rotatably connected to the panel, pushes and pulls the panel between its angled positions and its upright position. A portal defined by a ballistic door viewer or viewport is located in the panel and permits viewing or observing through the panel. A release system is configured to deactivate the stop and enable the device to move.

    摘要： A moveable barrier system comprising a first panel having a first vertical edge and a second vertical edge, the first vertical edge rotatably coupled to a first vertical surface along a first axis, and a second panel having a third vertical edge and a fourth vertical edge, the third vertical edge of the second panel rotatably coupled to the second vertical edge of the first panel, the fourth vertical edge of the second panel removably coupled to a second vertical surface. Each of the first and second panel have a structural layer that forms a vertical plane, spanning the first vertical edge and the second vertical edge, and a projectile resistant layer that is resistant to projectile impact. The first panel and the second panel are configured to move from a stored position into an active position when in use.
