  • Publication number: 20190319451
    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.

  • Publication number: 20190234903
    Abstract: An insulated pipe includes an elongated tube having a first end, a second end, and a sidewall extending therebetween; and an insulating member at least partially enclosing a portion of the sidewall, including at least one channel extending through at least a portion thereof. The insulated pipe also includes at least one coaxial moisture sensor positioned within at least a portion of the channel configured to sense moisture in the channel. The at least one coaxial moisture sensor includes: a dielectric member having a sleeve defining a center hole formed from an absorbent dielectric polymer material; an outer electrode electrically connected with an outer surface of the dielectric member including a moisture permeable sleeve which permits moisture to pass to the dielectric member; and an inner electrode having a wire extending through the center hole of and electrically connected with an inner surface of the dielectric member.

  • Publication number: 20190122598
    Abstract: A system for controlling light transmittance includes a panel which is capable of at least one of darkening and lightening in response to applied electric voltage and/or current. The panel includes at least one substrate, an electrically conductive coating on at least a portion of a surface of the at least one substrate forming at least one electrode, and an electrochromic medium covering portions of the at least one substrate and the at least one electrode and in electrical communication with the electrode. The system further includes a power supply in electrical communication with the at least one electrode and a controller in communication with the power supply configured to cause the power supply to apply a voltage and/or current to the at least one electrode according to a predetermined pattern for controlling the transmittance of the panel. The predetermined pattern comprises a plurality of micro-pulses which are less than or equal to 0.5 second in duration.

  • Patent number: 9983171
    Abstract: A transparency, e.g. an aircraft laminated windshield, includes one or more moisture sensors to monitor moisture penetration to monitor performance of the moisture barrier. At least one of the moisture sensors includes a dielectric between and in electrical contact with two electrically conductive electrodes. Alternating electrical current is applied to the electrodes to measure the complex impedance (ohms) of the dielectric to determine the amount of moisture within the laminated windshield in the area of the moisture sensor. With the information provided by the moisture sensors performance of the windshield is available to schedule timely repair or replacement of the windshield that is performing outside of acceptable limits.

  • Patent number: 9384601
    Abstract: An initial electronic fingerprint for a vehicle and selected component of the vehicle, e.g. an aircraft windshield having a heatable member, is made. During operation of the aircraft, the initial electronic fingerprint of the aircraft and a real time electronic fingerprint of the aircraft are compared to determine the operating performance of the heatable member. The parameter that provides the performance of the component includes a time count within a predetermined time period. As the time count increases during the predetermined time period, the performance of the heatable member toward unacceptable performance increases.
