Abstract:
Interconnections are formed between electronic devices embedded in a "smart" textile panel. A highly bendable drawn fiber in the panel includes continuous and/or discrete active elements encapsulated in a flexible matrix. E-fabrics include vias forming interconnections between conductors included on or in the fabric. A flexible connection pad of alternated conducting and insulating elastomer regions forms a plurality of interconnections between an external device and the conductors of an e-fabric. E-fabrics are formed by preassembling conductors with ribbons of adhesive to form conducting assemblies, and then bonding the conducting assemblies to fabric or to pre-manufactured garments, including across seams thereof. A garment such as a hoodie includes position, orientation, flexion, and/or acceleration sensors that enable a user to control aspects of an audiovisual concert such as volume, balance, tone, recorded feedback, and mashups, as well as light displays and pyrotechnics by physical gestures.
Abstract:
An MFA panel provides enhanced compressibility and off-axis threat protection by distributing solid elements among a plurality of vertically stacked, flexible supporting sheets, so that the elements on each sheet are spaced apart while the stacked arrangement provides adjacent or overlapping coverage of the panel, while allowing the solid elements to slide over each other during compression. The solid elements can be triangular or square, and can be metal or ceramic. The supporting sheets can be high tensile, such as para aramid, or low tensile, such as PET, Nylon, or cotton, for enhanced compressibility, flexibility, drape, and hand. A high tensile backing ply can be included to inhibit tensile failure of low tensile supporting sheets. In embodiments, the panels are attached to each other only at their edges. Fibers of para aramid supporting sheets can be unidirectional, so as to share the load of an impact throughout the panel.

Abstract:
A glove that has a high percentage of low stretch materials and a method for the designing thereof provides an accurate fit to the majority of hand anatomies without relying on material stretch. The method includes determining a hand length, selecting four critical dimensions from among bridge length, thumb length, index finger length, middle finger length, ring finger length, and pinky finger length, and calculating the four selected dimensions such that ratios of the selected dimensions divided by the hand length fall within corresponding ranges, where the corresponding ranges are from 0.46 to 0.49 for the bridge length, from 0.61 to 0.63 for the thumb length, from 0.37 to 0.40 for the index finger length, from 0.40 to 0.43 for the middle finger length, from 0.37 to 0.40 for the ring finger length, and from 0.30 to 0.33 for the pinky finger length.
Abstract:
[0067] 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 KevlarTM. 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 2mm thick tiles and total thickness less than 5mm can provide V50 protection against 9mm FMJ projectiles at more than 1000 feet/second, and can also protect against knife and spike assaults at 65 Joules force.
Abstract:
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.
Abstract:
An implantable tissue grafting medical system and material using a combination of bio-absorbable and non bio-absorbable fibers and materials such as Poly Glycolic Acid (PGA) and polyester (PET), provides a permeable mesh or weave of fibers with an initial interstice size and permeability factor suitable to initial implant requirements, and a preengineered bio-absorption pattern and rate that controls the gradual expansion of interstice size within the mesh or weave in one or two dimensions up to a pre-engineered maximum interstice size, consistent with the anticipated rate of tissue regeneration on the implant, while retaining a primary grid or circumferential pattern of non-absorbable fibers at the maximum interstice size for supporting the new tissue for an extended period. Various means for combining materials to obtain initial interstice size, pattern and permeability, with the desired absorption pattern and rate, and the desired end point interstice size and spacing, are also disclosed.
Abstract:
An inflatable pipe tube fabric assembly for G-suits and medical appliances consisting of a continuously woven core fabric [32] separated at a first point in one yarn direction by weaving methods into two fabric layers [38] to form a flexible fabric tube between adjacent sections of the core fabric; this process is repeated progressively to form an ssembly of multiple, adjacent fabric tubes from a single core fabric weaving process. A manifold connects the fabric tubes for increased user support when selected criteria are met.

Abstract:
A flexible, penetration resistant structure has a solids layer with a pattern of intersecting gap lines with critical gap cross section geometry, a flexible fiber or fabric layer backing, and a critical bonding layer attaching the solids layer to the flexible backing layer; where the gap geometry upon impact by a select penetrator type causes a controlled response and distributes impact energy in the structure, placing elements of the solids layer adjacent to the impact point mainly in vertical and lateral compression, the bonding layer mainly in shear, the fabric layer beneath the point of impact mainly in bending pressure, and the fibers within the fabric layer, particular those fibers perpendicular to the axis of the gap segment impacted, mainly in tension; and where the applicable class of penetrators is loosely defined as within a certain range of striking energy per unit area of penetrator contact area cross section.
