Abstract

In one embodiment, the present invention includes an apparatus to heat a body. A first conductive path and/or a second conductive path include a resistive heating element that produces heat from said current. The first conductive path is coupled to redirect the current to the second conductive path and set up complementapy magnetic fields between said first and second layers. A third layer substantially blocks an electric field produced from the resistive heating element included in the first layer and/or second layer.

Claims

1. An infrared apparatus for a sauna, said sauna including a plurality of walls that define an internal space, said infrared apparatus to heat said internal space, said infrared apparatus comprising:

a first layer having a first conductive path coupled to pass a current;

a second layer having a second conductive path running coincident to said first conductive path; and

a third layer situated between an interior of said internal space and said first and second layers,

wherein at least one of said first conductive path and said second conductive path includes a resistive heating element that produces heat from said current,

wherein said first conductive path is coupled to redirect said current to said second conductive path and set up complementary magnetic fields between said first and second layers, and

wherein said third layer substantially blocks an electric field produced from the resistive heating element included in the at least one of said first layer and said second layer.

2. The infrared apparatus of claim 1, wherein a first magnetic field generated on said first layer is canceled by a second magnetic field generated on said second layer.

3. The infrared apparatus of claim 1, wherein said third layer is a conductive fabric.

5. A sauna comprising:

a plurality of walls that define an internal space; and

an infrared heating system comprising;

a first layer having a first conductive path coupled to pass a current;

a second layer having a second conductive path running coincident to said first conductive path; and

a third layer situated between an interior of said internal space and said first and second layers,

wherein at least one of said first conductive path and said second conductive path includes a resistive heating element that produces heat from said current,

wherein said first conductive path is coupled to redirect said current to said second conductive path and set up complementary magnetic fields between said first and second layers, and

wherein said third layer substantially blocks an electric field produced from the resistive heating element included in the at least one of said first layer and said second layer.

6. The sauna of claim 5, wherein said third layer is a conductive fabric.

7. The sauna of claim 5, wherein said third layer is coupled to ground.
