Abstract:
1. An electrically conductive laminate for heating or warming, comprising: first and second substantially electrically insulating material sheets adhered to one another on confronting surfaces, first and second electrical conductor means provided between the confronting surfaces of the sheets, and a plurality of patterns on a portion of the confronting surface of the first sheet, wherein said patterns are arranged serially and coextensively with the electrical conductor means so as to have a plurality of regions of intersection between the patterns and the electrical conductor means, wherein the patterns are selected to provide electrical conductivity, wherein a portion of at least one of said patterns electrically contacts the conductor means at regions of intersection, and wherein at least one region of intersection further comprises a means to selectively interrupt the electrical contact of at least one of the electrical conductor means.
