Inductively heated windshield wiper assembly
First Claim
1. An inductively heated wiper assembly for a windshield having an inner surface, an opposed outer surface, and a thickness between the inner and outer surfaces, said assembly comprising:
- a wiper configured for removing water or other substances from the outer surface of said windshield, the wiper including an inductively heatable portion; and
an induction work coil operable to generate an alternating magnetic induction field and configured to be placed separate from and in spaced relationship to the wiper and proximal to said inner surface of said windshield remote from said wiper, to inductively heat the inductively heatable portion of the wiper by passage of said magnetic induction field generated by said induction work coil unit through the thickness of said windshield.

Abstract
A wiper assembly having a wiper with an inductively heatable portion, and an induction heating device including an induction work coil which is configured to be placed near the wiper to inductively heat the inductively heatable portion. The inductively heatable portion may be in the wiper blade, the wiper arm which supports the blade, or both. The induction work coil may be placed on or near the windshield or other surface which is cleaned by the wiper and may heat the wiper regardless of its position or only when the wiper is at a specific location such as its retracted “rest” position. The wiper assembly may also include a temperature sensor for sensing a current temperature of the wiper and control circuitry associated with the induction heating device for controlling operation of the work coil.)

8. An inductively heated wiper assembly for a windshield having an inner surface, an opposed outer surface, and a thickness between the inner and outer surfaces, said assembly comprising:
-
a wiper configured for removing water or other substances from the outer surface of a said windshield; a susceptor coil for placement in contact with a portion of the wiper; and an induction work coil operable to generate an alternating magnetic induction field and configured to be placed separate from and in spaced relationship to the wiper and proximal to the inner surface of said windshield remote from said wiper, to induce current in the susceptor coil to heat the susceptor coil or a heating element in electrical contact with the susceptor coil, by passage of said magnetic induction field generated by said induction work coil through the thickness of said windshield. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. An inductively heated wiper assembly for a windshield having an inner surface, an opposed outer surface, and a thickness between the inner and outer surfaces, said assembly comprising:
-
a wiper configured for removing water or other substances from the outer surface of a said windshield; a resonant susceptor coil for placement in contact with a portion of the wiper; and an induction work coil operable to generate an alternating magnetic induction field and configured to be placed separate from and in spaced relationship to the wiper and proximal to the inner surface of said windshield remote from said wiper, to induce current in the resonant susceptor coil to heat the resonant susceptor coil or a heating element in electrical contact with the resonant susceptor coil, by passage of said magnetic induction field generated by said induction work coil through the thickness of said windshield.

17. A system for inductively heating a wiper operable to remove water or other substances from the outer surface of a windshield having an inner surface, an opposed outer surface, and a thickness between the inner and outer surfaces, the system comprising:
-
an induction work coil operable to generate an alternating magnetic induction field and configured to be placed separate from and in spaced relationship to the wiper and proximal to the inner surface of said windshield; and a susceptor coil configured to be placed proximal to said outer surface of said windshield for heating the wiper when subjected to a current induced by the induction work coil, said magnetic induction field passing through the thickness of said windshield from said induction work coil to said susceptor coil to induce said current in said susceptor coil. - View Dependent Claims (18, 19)
