Patent number: 6730622Abstract: An electrical cable of the present invention comprises a plurality of spaced, parallel flat conductors. Each of the plurality of flat conductors was previously integral with each immediately adjacent flat conductor. A dielectric material is holds the conductors in the spaced, parallel relationship. The dielectric material can be a polymer film, a nonwoven, or other polymer materials such as PTFE, or expanded PTFE. The cable of the present invention is made by providing first and second webs of dielectric materials and a third sheet of conductive material. The first and second web materials are bonded to the third sheet of conductive material in a face-to-face layered relationship thereby forming a bonded laminate. The bonded laminate is then incrementally stretched to separate the sheet of conductive material in to spaced, parallel flat conductors.Type: GrantFiled: June 21, 2001Date of Patent: May 4, 2004Assignee: The Procter & Gamble CompanyInventors: John Joseph Curro, Douglas Herrin Benson, John Brian Strube

Publication number: 20030129905Abstract: Methods and systems for selectively connecting and disconnecting conductors in a fabric are disclosed. First and second conductors are integrated into a fabric such that the conductors intersect at a crossover point. The conductors are bonded to each other at the crossover point to improve AC and DC characteristics. Disconnect areas may be provided near the crossover point to allow selective disconnection of the conductors from the crossover point.Type: ApplicationFiled: January 8, 2002Publication date: July 10, 2003Inventors: Anuj Dhawan, Tushar Kanti Ghosh, John Muth, Abdelfattah Seyam
