Patent ID: 7230213

Claim:
A modular heated cover comprising: a first pliable outer layer configured for durable protection in an outdoor environment; a second pliable outer layer configured for durable protection in an outdoor environment; a pliable electrical heating element configured to convert electrical energy to heat energy comprising, a resistive element for converting electrical current to heat energy and a substantially planar heat spreading element comprising graphite, the heat spreading element configured to distribute the heat energy generated by the resistive element more readily within a plane of the heat spreading element than out of the plane of the heat spreading element; the pliable electrical heating element disposed between the first and the second outer layers such that the pliable electrical heating element evenly distributes heat over a surface area defined by the first and the second outer layers and an electrical insulation layer disposed between the resistive element and the heat spreading element; a thermal insulation layer positioned above the pliable electrical heating element and between the first and the second outer layers such that heat from the pliable electrical heating element conducts away from the thermal insulation layer; a receiving power coupling electrically connected to the electrical heating element, the receiving power coupling configured to couple to a power source; and wherein the first and second outer layers are configured to cooperate to retain air beneath the modular heated cover.
