    摘要: A flexible, foldable EM barrier attenuates electromagnetic radiation by at least 20 dB from 1 GHz to 30 GHz. The barrier includes an LF layer that blocks EM radiation at least at low frequencies, laminated to a textile support layer that reduces stress cracking of the LF layer and prevents widening of any cracks that do form. Embodiments further include an HF layer that blocks EM radiation at high frequencies, such as a metallized polymer film and/or an elastomer layer filled with conductive particles. The LF layer can be foil, mesh, or electroless metallization of the support textile or of another textile. A thermal insulation layer can be included. A topcoat can block UV, and primer layers can resist moisture. Barriers can be joined to each other and/or to adjacent structures by lanyards, webbing, sewing, soft connections, and/or flex joints formed by adhesively attached metallized textiles or films.

    摘要: An apparatus for protecting a power tool user includes a glove or other garment having at least one sensor that monitors proximity to the power tool. Glove embodiments can include finger and/or thumb proximity sensors, and/or sensors that detect hand position, finger and/or wrist joint angle, vibration, and/or acceleration. Sensing targets can be retroactively installed on the power tool, and can define warning and/or danger zones. Sensing can be via magnetic, electromagnetic, capacitive, eddy current, and/or range finding means. Sizes of warning and/or target areas can be controlled by selecting targets from a plurality of targets of various detection ranges. Protective responses can vary according to different sensed events, and can include audible, visual, and/or tactile alerts, and/or interruption of power to the tool. Embodiments can record proximity and/or status data during a work session for review, training, and certification purposes. A controller can be physically cooperative with the garment.

    摘要: A camouflage system adaptively matches the visible and IR spectrum of surrounding vegetation. A bio-chromophore dye solution circulated through an upper channel and distributed by a pulp or fabric matches the visible and biological IR spectrum, while water evaporated from the upper channel or from a separate lower channel matches the water IR spectrum. Dye can be retained in the pulp or continuously circulated. Permanently printed colors and/or patterns can also be included. Petalation cooperative with a channel flow pattern can release evaporated water and inhibit LiDAR detection. An upper waxy layer and surface embossing can avoid specular reflections. The camouflage signature can be compared with the environment and automatically adjusted as needed. Embodiments include thermal management, electromagnetic shielding, and/or radar scattering/absorbing subsystems. An airbag ground plane can match a terrain contour and avoid LiDAR detection. Multiple zones can provide adaptive display of visible and IR patterns.

    摘要: The present invention is a method for coloring knit, woven, or non-woven protective textiles made from yarns containing at least 20% synthetic high tenacity fibers, such as para-aramid or liquid crystal polyester (“LCP”), and for package-dyeing and skein-dyeing of such yarns. In embodiments, the textile is scoured to remove any impurities. A base coating of an adhesion promoting primer is then applied, which is typically a polymer or elastomer. The textile is typically immersed at zero tension in the primer liquor for an extended period. Afterward, the primer is dried and then cured at an elevated temperature to cross-link the primer and provide wash-fastness. A dye or printing ink of substantially any desired color and intensity is then applied. The protective yarns can include staple fibers and/or continuous filament fibers. The invention is further applicable to drum coating, jig processing, dye beck and other dying and coating processes.

    摘要: A flexible mosaic armor system that defeats threats at any attack angle includes top and middle solid elements layers separated by uniform gaps that intersect at apexes. The top elements can have a “hem” shape with raised edges. The middle elements can be flat, or can also have a hem shape. In embodiments, the edges of the top and middle layers are aligned and separated by an offset that is three or four times the gap width. Off-axis spike and needle strikes are thereby trapped between the two solid element layers, without added textile reinforcement. Embodiments include an apex layer of solid elements that overlap the first layer apexes, the apex layer being the second layer or a third layer beneath the 2 upper layers. The apex layer can be sandwiched between two textile backer layers that provide a full uninterrupted bonding surface to all of the solid element layers.

    摘要: A new class of protective fabrics having good ballistic and fragmentary protection also provide wearable drape, softness, and moisture transport, as well as good UV and abrasion resistance and color acceptance, making them comfortable to wear as garment fabrics. The protective fabrics are constructed from yarns having at least 20% ballistic fibers with greater than 12 gpd tenacity. A combined cover factor of between 55% and 80% avoids added stiffness due to yarn distortion at the crossing points. In embodiments, a long-float weave such as twill or satin with reduced crossing point density improves the hand of the fabric, and in some embodiments provides a different character on each face so that a predominantly staple fabric face is in contact with skin of a user, thereby providing better wearing comfort than a plain weave.

    摘要: A tire having reduced mass and low rolling resistance and a method of manufacture thereof achieves reduced weight by using thin layers of thermoplastic polyurethanes (“TPU's”) to heat seal the carcass, breaker, and tread layers of the tire to each other, rather than embedding the layers in conventional, relatively thicker and heavier layers of sulfur cured vulcanized carbon filled elastomers. Creep and “spring-back” of the thermoplastic polyurethanes during cure is avoided by maintaining the adhered layers under pressure until the assembly cools below its glass transition temperature. In embodiments, the heat sealing can be performed on the forming drum, and in some embodiments cool rollers are applied to the heat-sealed carcass so as to accelerate the cooling to below the glass transition temperature.
