  • Patent number: 11509132
    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.
