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;
at least one temperature sensor comprising a sensory portion connected to the windshield configured to detect a signal representative of a temperature of at least a portion of the windshield;
a heater controller spaced apart from and in electrical contact with the windshield via at least one power line and with the temperature sensor; and
a power supply electrically connected to the windshield and heater controller 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,wherein the heater controller comprises an arc detection system comprising a sensory portion configured to detect voltage or current of an electrical signal passing through the at least one power line from one of the bus bars to the heater controller and an evaluation unit configured to disconnect the power supply from the heating arrangement based on the signal detected by the sensory portion of the temperature sensor or the voltage or current detected by the arc detection system.

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.
