Intelligent Window Heat Control System
First Claim
1. A windshield monitoring system, comprising:
- a windshield comprising a heating arrangement for removing fog, ice, and/or snow from the windshield, the heating arrangement comprising a pair of spaced bus bars and an electrically conductive coating covering at least a portion of the windshield extending between and in electrical contact with the spaced bus bars;
a cabinet configured to store one or more electronic devices spaced apart from and in electrical contact with the windshield via at least one power line;
a power supply electrically connected to the windshield through the at least one power line, the power supply being configured to provide electrical current through the bus bars and through the electrically conductive coating to heat the electrically conductive coating, thereby heating at least an outer surface of the windshield; and
an arc sensor comprising a sensory portion electrically connected to and configured to detect voltage or current of a signal passing through the at least one power line from one of the bus bars and an evaluation unit in the cabinet configured to disconnect the power supply from the heating arrangement based on the voltage or current detected by the sensory portion of the arc sensor.

Abstract
A system for monitoring performance of an aircraft windshield includes a sensor comprising a sensory contact and an evaluation unit. The sensory contact is in physical contact with one or more components of the windshield, and generates a signal representative of the performance of the component(s) of the windshield. An electrical connector is secured to the surface of the windshield facing the interior of the aircraft. The signal from the sensory contact passes through the connector to the evaluation unit. The evaluation unit acts on the signal to determine the performance of the component(s) of the windshield, wherein the evaluation unit is spaced from and out of physical contact with the windshield and the electrical connector, and is in electrical contact with the electrical connector.
