Induction Heating System
First Claim
1. An induction heating system comprising:
- a first article having a metallic mesh lining; and
a second article having a coil for receiving an alternating electrical current;
wherein the coil induces a current in the metallic mesh lining when the second article is placed in close proximity to the first article and the coil receives an alternating electrical current;
whereby the current induced in the metallic mesh lining causes the metallic mesh lining to generate heat that can be applied to a body through contact with the first article.

Abstract
The invention is an induction heating system comprising a first article having a metallic mesh lining; and a second article having a coil for receiving an alternating electrical current; wherein the coil induces a current in the metallic mesh lining when the second pad is placed in close proximity to the first pad and the coil receives an alternating electrical current; whereby the current induced in the metallic mesh lining causes the metallic mesh lining to generate heat that can be applied to a body through contact with the first article. Additionally, this inventive induction heating system may further comprise a controller circuit in the second article for detecting an eddy current in the coil and operating a switch to turn the alternating electrical current off when no eddy current is detected in the coil.

14. An induction heating system comprising:
-
a compressible pad having a first surface and a second surface; a flexible metallic sheet attached to the first surface of the compressible pad; a seat for supporting the second surface of the compressible pad; and a coil in the seat for receiving an alternating electrical current; wherein the coil induces a current in the flexible metallic sheet when the coil receives an alternating electrical current and the compressible pad is compressed, thereby placing the flexible metallic sheet in close proximity to the seat; whereby the current induced in the flexible metallic sheet causes the flexible metallic sheet to emit heat. - View Dependent Claims (15)

16. An induction heating system comprising:
-
a first article having a resistance means for resisting an electric current; a field generating means for producing a magnetic field around a second article when an alternating electrical current is applied to the field generating means; wherein the magnetic field induces a current in the resistance means when the field generating means is placed in close proximity to the first article; whereby the current induced in the resistance means causes the resistance means to generate heat that can be applied to a body through contact with the first article. - View Dependent Claims (17)
