摘要： A proximity sensor assembly includes a multilayer printed wiring board proximity sensor, the proximity sensor being operable as either a variable-reluctance sensor or an eddy current loss sensor. The proximity sensor includes a plurality of layers configured to form at least one wound coil disposed about at least a portion of a core. The coils are electrically driven to generate an alternating magnetic field such that the inductance of the coils changes when a permeable or conductive object is moved in relation to the magnetic field. The change in inductance is recognized and used to detect the proximity and presence of an object relative to the sensor.

摘要： A method of fabricating a multilayer wiring board proximity sensor includes forming a laminate, and fabricating a plurality of through-conductors through the layers of the laminate. The laminate has a plurality of layers including one or more core layers and a plurality of coil layers. Each core layer includes a core pattern formed of a permeable material, and each coil layer comprises at least one coil trace formed of a conducting material. Thus, the through-conductors may be fabricated through the layers of the laminate such that the coil traces are interconnected by the through-conductors to thereby form one or more coils disposed about at least a portion of the core patterns of the core layers.

摘要： An ultrasonic transducer is disclosed comprising a layer of piezoresonator material capable of transmitting from a top surface thereof an ultrasonic pulse into a tank of liquid and receiving at the top surface reflections of the transmitted pulse from the liquid; and a matching layer of pure crystalline Boron Nitride disposed on the top surface. The pure crystalline Boron Nitride layer is operative to match the acoustic impedances of the piezoresonator material and the tank liquid about the operational frequency passband of the ultrasonic pulse. The ultrasonic transducer may be disposed in an assembly for measuring a quantity of liquid in the tank. The assembly comprises a housing having a top surface for interfacing with the liquid of the container; the ultrasonic transducer disposed therein, the top and bottom surfaces of the piezoresonator layer covered with layers of conductive material; and a lead wire for each surface of the piezoresonator layer connected at one end to the conductive material layer thereof, the lead wires connectable at the other ends to a transducer driver/receiver circuit. The matching layer of pure crystalline Boron Nitride disposed on the top surface of the piezoresonator layer is configured as a window between the piezoresonator layer and the liquid at the top surface of the assembly. A surface of the matching layer at the liquid interface is covered with at least one metal layer.

摘要： A system for an icing resistant sensor port assembly includes shaped and patterned features for resisting the formation and propagation of ice around a sensor port, such as for a pressure sensor in an aircraft fuel tank. Water may be present in fuel tanks due to condensation and other factors. The water, being heavier than fuel, such as jet fuel, sinks to the bottom of the tank and may be present around the sensor port. If the water completely fills the pressure port, it may damage the sensor. In various embodiments, an inlet assembly having a cone-shaped countersink, sharp edges that reduce surface area, anti-wetting coatings, and slots to allow fluid flow within the inlet assembly, among other features, may be used to help resist ice formation and propagation around a sensor port.
