Abstract: An under floor heating element incorporating a scrim having one or more pairs of heating and/or sensor wires arranged in a continuous pattern such that pair members are disposed in crossing relation to one another. The pair members may be cut and joined to establish electrical connections at defined crossing points to establish feedback loop circuits with a control element.

Abstract: A warming mattress and mattress pad incorporating an insert layer or sheet with a scrim having one or more pairs of heating and/or sensor wires arranged in a continuous pattern such that pair members are disposed in crossing relation to one another. The pair members may be cut and joined to establish electrical connections at defined crossing points to establish feedback loop circuits with a control element.

Abstract: A warming blanket incorporating channeled areas for accepting heat and/or sensor wires. The inventive blanket includes multiple layers of knitted, woven or non-woven fabrics that are welded together with ultrasonic seams to define channels through which wires for resistive heating can be placed. This composite may be produced in a continuous process, providing the composite in roll form.

Abstract: A warming mattress and mattress pad incorporating channeled areas for accepting heat and sensor wires. The inventive mattress and mattress pad includes an arrangement of seam structures defining channels housing substantially discrete elongate heating and sensing elements arranged in a substantially similar pattern within the mattress or mattress pad interior.
