A magazine mount includes a mechanism to releasably hold a weapon magazine in a substantially upright orientation, wherein the mechanism to releasably hold the magazine includes a rectangular housing having an open top and sidewalls, and an axle pin that is fit through a spool, allowing the spool to freely rotate on the axle pin, the axle pin is fit at opposite ends into longitudinal slots through each respective sidewall of the housing. At least one spring backed up by a portion of the housing, exerts a resilient force on the axle pin, urging the axle pin and the spool forwardly in the housing to press on a back end of a weapon magazine held in the housing. The housing has a retainer at a forward end having an underlying clearance to receive a forward side lip of a weapon magazine.

A family of new and novel molecules for mechanically superior two-dimensional (2D) polymers is described herein. By combining stiff carbon-containing cyclic polymer nodal units with more compliant linear polymer bridge units in an ordered, 2D repeating molecular structure it is possible to tailor the mechanical properties of 2D polymers and their assemblies to provide high stiffness, strength, and toughness. Furthermore, the inherent dimensionality of 2D polymers and their ability to be stacked into ordered and chemically interactive ensembles gives them inherent benefits in a variety of barrier and structural applications over current stiff and strong linear polymer technologies.

A system, method, and blocking pad for receiving strikes from a special individual. The blocking pad includes a pad configured to receive the blows from the special individual. The blocking pad further includes a number of handles connected to a back of the pad. The number of handles include at least two handles in a middle portion of the back of the pad and at least a handle at ends of the pad.

Apparatus and methods for reducing injury or damage from an explosive device are disclosed. An example apparatus includes a housing and at least one inflator coupled to the housing. The apparatus also includes a shield coupled to the housing. The shield has a plurality of channels coupled to the at least one inflator. The shield also has a compact position and an expanded position. The plurality of channels are configured to receive a fluid from the at least one inflator and thereby at least partially advance the shield from the compact position to the expanded position.

A bench including a first support, a second support, a seat, and one or more protective metal plates. The seat extends between the supports. The metal plates extend above the seat or below the seat, or both, and provide at least NIJ Level IIA, preferably Level IV, ballistic protection. The metal plates are attached to the bench, partially or completely, via one or more reversible toolless connections such as a slotted hole and headed stud. The bench can be assembled and disassembled in the field by unskilled labor with few or no tools required.

A threat-resistant shield attached to an object, the threat-resistant shield including a main body including a cushioning material, a threat-resistant material adapted to prevent penetration therethrough that covers a portion of the main body, a transmitter disposed in the main body portion, and an external trigger mechanism that is electrically connected to the transmitter, the external trigger mechanism being fastened to the object such that detaching the threat-resistant shield from the object causes the external trigger mechanism to trigger the transmitter to transmit a signal to a remote server.

An example barrier can be switchable between an at least partially collapsed state and at least partially expanded state (e.g., a deployed state). For example, the barrier can be formed from a sheet and a plurality of rigid sections (e.g., rigid panels) attached or incorporated into the sheet. The barrier can also include a plurality of hinges, such as hinge lines, between the panels that are formed from the sheet. The hinges enable the barrier to be rigid foldable (e.g., the hinges can fold and unfold while the rigid sections remain stiff and rigid) between the expanded and collapsed states.
