Abstract
An electric blanket has a woven web of warp and weft fibers. At least a portion of the warp fibers are electrically conductive. At least a portion of the weft fibers are electrically conductive and interweave with the electrically conductive warp fibers at a first area of the web. A power source in electrical communication with the web applies a voltage to the web that produces a wide area electrical distribution at the first area.
Claims5
An electric blanket, said blanket comprising:
- a woven web comprised of warp and weft fibers,
- wherein at least a portion of the warp fibers are electrically conductive, and
- wherein at least a portion of the weft fibers are electrically conductive and interweave in electrical contact with the electrically conductive warp fibers at a first area of the web;
- a power source in electrical communication with the web so that the power source applies a voltage to the web that produces a wide area electrical distribution at the first area.
1 more element
An electric blanket, said blanket comprising:
- a woven web comprised of warp and weft fibers,
- wherein a first group of said warp fibers are electrically non-conductive and a second group of said warp fibers are electrically conductive,
- wherein a first group of said weft fibers are electrically non-conductive and a second group of said weft fibers are electrically conductive, and
- wherein said second group of warp fibers and said second group of weft fibers interweave in electrical contact with each other at a central area of the web;
- a pair of electrically conductive wires separate from each other and in electrical contact with the second group of warp fibers and the second group of weft fibers;
- a power source in electrical contact with the pair of conductive wires so that the power source applies a voltage across the conductive wires that produces a wide area electrical distribution at the central area.
