|20120295063||Low roughness high surface-energy, anti-microbial fabric - A self-decontaminating fabric is manufactured from fibers such as Tencel having high surface energy and low surface roughness. Novel scouring methods eliminate substantially all contaminants from the fibers, and a novel coating process applies an anti-pathogen coating such as a halogen compound to the fabric so as to provide rapid deactivation of pathogens on contact. Novel charging methods activate or reactivate the coating, typically by exposure to chlorine. The coating is substantially free of gap regions where pathogens can survive. The high surface energy of the fibers allows a high coating concentration and provides close contact between attached pathogens and the coating. The low surface roughness reduces the pickup of pathogens by the fibers. Multi-layer embodiments include an outer layer configured for maximum anti-pathogen coating concentration, and an inner layer configured for a reduced coating concentration that is compatible with skin contact.||11-22-2012|
|20120219609||PATHOGEN PROTECTION GARMENT WITH BOTH RAPID AND PERSISTENT RECHARGABLE SELF-STERILIZATION - A moisture-permeable glove or other garment protects against user contamination and cross-contamination by providing both rapid and persistent sterilization. Exposure to halogen of inherent NH groups and/or attached hydantoin can form a persistent outer halamine sterilization layer. A second inner halamine layer intercepts any pathogens that penetrate the outer surface. The garment can be single layer, or can include a detachable inner liner. Embodiments are compatible with rapid decontamination using an alcohol-based agent. Some embodiments provide a 180 second 3-log kill rate for at least||08-30-2012|
|20120159680||THERMALLY VENTED BODY ARMOR - A modular and field adaptable body armor system includes a plurality of flexible, air-permeable, thermally vented plates arranged in fixed relationships that pro-vide flexible, modular, field-adaptable protection for the torso and extremities without excessive weight or heat bur-den. The TVA plates include protective cards suspended in a parallel, louvered relationship between inner and outer mesh layers, thereby permitting air to flow therebetween while providing a flexible, compressible, modular barrier that protects the torso and extremities against projectiles. In embodiments, the outer mesh layer resists penetration and compresses cards together to intercept a projectile that would otherwise pass therebetween. Protective cards can include thermally pressed and flexed laminated UHMWPE. TVA panels can be removed and exchanged in the field according to the requirements of each mission. In embodiments, the TVA plates are laced together and/or attached to an underlying fabric carrier garment.||06-28-2012|
|20120152098||SOFT PLATE SOFT PANEL BONDED MULTI LAYER ARMOR MATERIALS - A flexible armor system includes a rigid panel of a stiffness calculated to resist penetration by a known ballistic object, made from multiple layers of Ultra High Molecular Weight Poly-Ethylene fibers or other high tenacity fibers, which is then pre-flexed beyond its elastic bending limit to create a distributed pattern of surface buckling, with localized areas of interior delamination, which together function as bending or hinge lines to provide flexibility to the otherwise rigid panel and thereby lower its overall stiffness to less than that calculated for the rigid panel to resist the ballistic object. The areas of delamination have a width of less than one half the diameter of the ballistic object.||06-21-2012|
|20110296979||TITANIUM MOSAIC BODY ARMOR ASSEMBLY - An assembly useful for constructing concealable, flexible, lightweight protective body armor includes a flexible support layer to which is bonded a mosaic of rigid, adjacent tiles having a high bending performance, such as type 5 titanium alloy, which includes 6% aluminum and 4% vanadium by weight. The inner support layer can include woven para-aramid and/or STF-treated Kevlar™. The tiles can have interlocking and/or thickened edges. An additional backing layer can include para-aramid and/or carbon nanofiber embedded UHMWPE UD-laminate. An inner layer can have high moisture transport, anti-microbial properties, and low friction. An outer layer can be shaped with anatomical features to hide the armor. The assembly can be flame resistant. Assemblies with 2 mm thick tiles and total thickness less than 5 mm can provide V50 protection against 9 mm FMJ projectiles at more than 1000 feet/second, and can also protect against knife and spike assaults at 65 Joules force.||12-08-2011|
|20110271825||SUICIDE BOMBER BLAST THREAT MITIGATION SYSTEM - A non-lethal, sabot-deployed blast shield mitigates a suicide bomber by wrapping around the bomber and positioning a plurality of protective layers over an explosive device to absorb emitted heat, shock waves, and projectiles if the device is detonated. Stand-offs such as inflatable beams or pillows provide break-away zones between the protective layers, allowing some layers to expand to a point of failure and absorb the maximum possible energy. Inner layers absorb shock waves and heat. One or more outer layers resist projectile penetration. Protective layers can be positioned on opposing sides of a suspect in case two explosive devices are present. Shields can deploy with sufficient energy to knock down a bomber. In embodiments, a plurality of shields can be applied without interference therebetween. In some embodiments, a round shield includes bolas which spread the shield in flight in a cast-net dynamic and wrap around the suspect for shield attachment.||11-10-2011|
|20110123757||BREATHABLE CHEMBIO PROTECTION FABRIC WITH CARBON NANOTUBE PHYSICAL PATHOGEN BARRIER - A fabric for use in chemical and biological (CB) protective garments includes at least one felt layer having from 25% to 100% carbon nanotube (CNT) fibers as a breathable physical barrier against toxic chemical droplets and/or pathogens. The felt layers are cleaned and consolidated into a mechanically competent sheet which can form adhesive seams having lapshear greater than the sheet itself. An additional supporting layer can be included. The supporting layer can be a wicking layer which is permeable with a chlorinated or otherwise chemically active solution to establish a reactive chemical barrier, the solution being dispensed on demand from a portable container. Embodiments include a second layer of CNT or of another backing fabric, sandwiching the wicking layer therebetween. Impermeable fluoropolymer seams can divide the fabric into a plurality of CNT/wicking cells. A layer of activated charcoal and/or halamine-forming hydantoin can be included for persistent reactive chemical protection.||05-26-2011|
|20110023697||MOSAIC EXTREMITY PROTECTION SYSTEM WITH TRANSPORTABLE SOLID ELEMENTS - A flexible armor system adaptable to a garment suitable for extremity protection uses a planar array of polygon-shaped solid elements which detach upon projectile impact and combine their mass with the projectile for reduced velocity and increased impact area. The solid elements are bonded between an elastic strike-side spall cover and a high tensile strength flexible backer layer, and are further supported by a substantial fiber pack. In embodiments, the solid elements are ceramic, and are commutated but remain essentially intact after the projectile impact. Edge bars can cover junctures between solid elements, and center buttons can cover intersections between the junctures. Edge bars and center buttons can also be ceramic. The ceramic parts can include titanium backing layers. After formation, ceramic cores can be compressed upon cooling by an outer ceramic layer having a higher coefficient of thermal expansion, the outer layer being formed by glazing or doping.||02-03-2011|
|20110002739||TEMPORARY FLOATING BREAKWATER AND CAUSEWAY WITH SIMULATED BEACH AND KELP - A durable, quickly deployable temporary floating breakwater (FBW) can protect areas in austere locations. A plurality of inflatable modules is encapsulated within a common cover, which holds the modules together and in some embodiments supports a causeway thereupon. A separate floating causeway can be included. Embodiments include a semi-permeable “sloping beach” section which causes waves to break before reaching the FBW. A bed of wave-energy-absorbing synthetic kelp can be attached to the sloping beach. The beach and/or kelp can include low-surface-energy fibers and films, such as olefins and polypropylenes, to remove oil from the water in case of an oil spill or accident. In embodiments, the FBW can be temporarily sunk to avoid extremely high seas, ice, and/or other surface hazards. The FBW is lightweight, can be quickly and compactly stowed, and in some embodiments can be transported and deployed from the deck of an LCU 1610.||01-06-2011|
