A method includes providing an article having an impact side and an asset side and exposing the impact side of the article to a plurality of pressure waves, the pressure waves having a plurality of pressure wave frequencies. The method also includes reflecting at least one composite harmonic of a portion of the pressure wave frequencies and reducing an amplitude of a portion of the pressure waves.

Embodiments of systems, methods, and devices for protecting service personnel by deploying a physical barrier are described. Further embodiments describe additional security features such as lights, sirens, cameras, electronic locks, timers, and/or notifying security personnel or local law enforcement when the system is activated.

The systems and methods disclosed herein relate to shielding electronic devices with respect to, among other things, projectiles. In some embodiments, an apparatus comprises a plurality of projectile-resistant panels corresponding to exterior surfaces of an electronic device. The apparatus wraps the electronic device, wherein each of the plurality of projectile-resistant panels covers a solid surface of the exterior surfaces of the electronic device and does not cover a perforated surface of the exterior surfaces of the electronic device. In further examples, the apparatus further comprises at least one fabric sheet forming a plurality of pockets in which to receive the plurality of projectile-resistant panels; and an articulation located between a pair of adjacent pockets of the plurality of pockets. The articulation facilitates the apparatus wrapping the electronic device by enabling rotation, relative to one another and about the articulation, between a first projectile-resistant panel and a second projectile-resistant panel.

A lightweight antiballistic plate assembly includes a ceramic antiballistic plate that is strengthened with a superhard protective layer attached to the strike face of the antiballistic plate. In one embodiment, a strike face of the plate has a layer of superhard material, such as polycrystalline diamond (PCD), attached by sintering. In one embodiment, the ceramic antiballistic plate is made from a mixture of silicon carbide and superhard protective strike face comprising a material selected from the group consisting of polycrystalline diamond (PCD), polycrystalline cubic boron nitride (PCBN), thermally stable polycrystalline diamond and combinations thereof.

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.

An armor system that includes a reactive armor component including a disruptive layer. The disruptive layer includes a plurality of three-dimensional geometric shapes each defining at least one hollow space and explosive material. The explosive material is deposited in the at least one hollow space. The disruptive layer also includes explosive material surrounding the geometric shapes and a layer of explosive material on top of the geometric shapes. The armor system may further include a non-reactive armor component.

A reinforced armor (200) and a process for reinforcing an armor by composite layering are provided. The reinforced armor (200) includes a core structure having a strike face and a back face, a first composite fiber laminate (220) having a plurality of composite fiber plies, bonded to the strike face of the core structure, and a second composite fiber laminate (225) having a plurality of composite fiber plies, bonded to the back face of the core structure. The process for reinforcing the armor includes creating the first and second composite fiber laminates from a plurality of plies of fibrous material impregnated with a resin matrix, and bonding the first and second composite fiber laminate to both the strike face and the back face. Advantageously, the reinforced armor (200) is capable of providing protection against hazards while having a light weight compared with a rigid armor such as steel or ceramic.

Multi-impact multi-layer body armor is presented. A first layer is a single layer of front covering material. A second layer, is a ballistic ceramic plate formed of a plurality of curved smaller ceramic tiles that are bonded together using a structural adhesive. A third layer formed of one or a plurality of aramid layers such as Kevlar® XP. A fourth layer formed of a rigid backing plate, formed of ultra-high molecular weight polyethylene such as Spectra Shield®. A fifth layer is a single layer of rear covering material. Thus, an improved body armor is presented which is inexpensive to produce, light, durable and can sustain multiple impacts.

An abrasion resistant material for use in the fabrication of protective garments that has at least two layers, a first layer and a second layer, wherein the first layer is the layer that is exposed to and engages with the abrasive surface, such as a road surface. The second layer comprises of substantially high tensile and burst strength so as to act as a protective layer which covers or is at least located closest to the skin of the wearer. The first layer has a plurality of abrasion resistant members dispersed throughout the first layer that act to absorb the bulk of any abrasion force and reduce the exposure and degradation of the second layer

The present invention relates to a flexible ballistic armor apparatus for deflecting high velocity firearm, fragmentation, or shrapnel projectiles with a flexible armor unit. The apparatus minimizes the deterioration of the armor when subjected to shock waves or shear forces of a ballistic impact. The present invention also relates to the use of a flexible armor unit with soft body armor, a vehicle, a vessel, an aircraft or in structural applications.
