A steel armor plate and method of manufacturing is described. The armor plate has three curves, a first curve about an axis that parallels the length of the armor plate, and two additional curves about axes that parallel the width of the armor plate. A die for manufacturing said plate is described, the die being formed of a stack of metal plates, each plate having a curve that substantially matches the first curve, the stack of plates being arranged in a step-down-then-step-up fashion to form a concavity that approximates one of the two additional curves.

A lumbar support system and device is disclosed herein which includes a lumbar support plate. The lumbar support plate may be incorporated or used in conjunction with a body armor protective garment.

Unidirectional transparent projectile penetration resistant panels and bidirectional opaque projectile penetration resistant assemblies and systems and methods of forming and mounting the same relative to underlying support structures.

A ballistic curtain system includes a curtain having cells configured to stop a high-speed projectile and a motor connected to the curtain. The motor is capable of deploying or retracting the curtain.

Unidirectional transparent projectile penetration resistant panels and bidirectional opaque projectile penetration resistant assemblies and systems and methods of forming and mounting the same relative to underlying support structures.

An RPG defeat system and method wherein a foam body is placed at a proximate a target. The foam body has a sufficiently low density to be pierceable by an RPG sensor without the RPG sensor being strained sufficiently to create a voltage. The foam body has a compressive strength sufficient to deform the RPG short circuiting a voltage pathway from the sensor to the RPG detonator. The foam body has a sufficient thickness and/or is spaced from the target to deform the RPG short circuiting the voltage pathway from the sensor to the RPG detonator before the sensor strikes the target and is strained creating a voltage.

A storage safe formed from a flexible fabric having a generally rectangular closeable outer shell, at least one longitudinal cable conduit channel and at least one latitudinal cable conduit channels and a plurality of wire cables of predefined length substantially disposed within said cable conduit channels wherein said longitudinal and latitudinal cables traverse the interior surfaces of the outer shell and further wherein said wire cable ends extend beyond said cable conduit channels; adjustable cable locks in operative contact with each wire cable end; at least one storage container disposed within said outer shell, wherein the wire cables are positioned within said wire conduit channels are drawn down upon and tightened on said storage container to form a wire cage and said each adjustable cable lock engages the opposite end of said wire cables end to securely lock the wire cables in place and further comprising a plurality of voids on a lower surface thereof and a separate cable segment and adjustable lock for securing said safe to a structure tie down.

Protective shields configured to prevent projection against projectiles, such as during excavating and/or mining operations, are provided. The protective shields include a base layer comprising one or more transparent polycarbonate layers, a sacrificial polycarbonate layer comprising a transparent polycarbonate, and an air gap positioned directly between at least a portion of the base layer and the sacrificial polycarbonate layer. The sacrificial polycarbonate layer is directly or indirectly attached to the base layer in a manner to provide the air gap positioned between the base layer and the sacrificial polycarbonate layer.

Structures based upon periodic cellular materials that provide a potential for defeating combinations of both air blast loading and ballistic attack either sequentially or simultaneously, or combination of both. The cellular structures may also be configured to meet the stiffness and strength support requirements of particular vehicle or other applications, systems or structures. The armor is therefore potentially able to support normal service loads and defeat blast and ballistic threats when necessary. The structure provides for using efficient load support capabilities of the material (without a high armor protection level) in low threat conditions, as well as the ability to modify the system to increase its level protection to a desired or required level. This would reduce the weight of the protection system in normal (low threat) conditions which reduces vehicle wear and tear, as well as cost savings in fabrication of applicable structures or systems.

Armor plating is provided for armored land vehicles or watercraft, the armor having a base armor plate and an additional armor plate fixed thereto on the enemy side, such that it can be removed. A structural component can be used as a base armor plate for such vehicles, and comprises a layered structure with a core composite having an inner honeycomb core and at least one covering layer. The layered structure does not contain supporting metal layers or ceramic, hard material layers. Another essential characteristic is the use of fixture elements which are anchored in the core composite to allow additional armor plating to be detachably fixed on the enemy side. The core composite therefore essentially offers basic protection itself, while also acting as the carrier structure for interchangeable additional armor plating.
