Abstract:

A windshield heater includes a substrate that is sized and shaped to cover a typical automotive windshield when placed adjacent an interior side of the windshield. The device includes one or more heating elements supported by the substrate, with the heating elements being connected to a power source to carry an electrical current or other means of producing heat throughout the heating elements. The heating elements radiate heat toward the windshield, thereby warming the windshield and either defrosting it or preventing frost from building up in the first place. The heater may include a timer and thermal control circuitry.
