  • Publication number: 20080287022
    Abstract: Coaxial and twisted pair conductive yarn structures reduce signal crosstalk between adjacent lines in woven electrical networks. A coaxial conductive yarn structure includes an inner conductive yarn having a plurality of conductive strands twisted together. An outer conductive yarn is wrapped around the inner conductive yarn. An insulating layer separates the inner and outer yarns. A twisted pair conductive yarn structure includes first and second conductive yarns, each including a plurality of conductive strands being twisted together. The first and second conductive yarns are twisted together to form a helical structure. In a woven electrical network, at least one conductor of adjacent conductive yarn structures is connected to ground to reduce signal crosstalk. Coaxial and twisted pair yarn structures may also be formed simultaneously with weaving or knitting the threads that make up the structures into a fabric.

  • Patent number: 4807303
    Abstract: Upper and lower body cold weather garments are provided which have excellent warmth, moisture permeability, wind resistance, and water resistance. The garment comprises an interior lining fabric, such as a loosely knit nylon lining, an outer fabric, and a layer of preponderantly open cell (e.g. polyurethane) foam at least 1/2 inch thick (preferably about one inch thick) between the interior lining fabric and the outer fabric, the components connected together by stitching at the edges of the garment. The outer fabric has air permeability of less than 15, and preferably less than 10, cubic feet per minute per square foot at 0.5 inches head of water, and has moisture vapor transmission of at least 1,000 grams per square meter per 24 hours. The outer or shell fabric preferably is woven from a fine denier, multi-filament, polyester yarn.
