    摘要： An apparatus includes a substrate and a plurality of conductive traces formed on the substrate. The conductive traces are doped with a concentration of an aluminum material forming a protective layer as a portion of the plurality of conductive traces to inhibit oxidation. A set of first metal contact pads are formed in contact with the plurality of conductive traces. The substrate, the plurality of conductive traces and the set of first metal contact pads define an electronic circuit board configured to operate at a temperature greater than 200 degrees Celsius. A high operating temperature electronic device is configured in electrical communication with the conductive traces defining an assembly configured to operate at a temperature greater than 200 degrees Celsius.

    摘要： A method of forming a silicon carbide transient voltage suppressor (TVS) assembly and a system for a transient voltage suppressor (TVS) assembly are provided. The TVS assembly includes a semiconductor die in a mesa structure that includes a first layer of a first wide band gap semiconductor having a conductivity of a first polarity, a second layer of the first or a second wide band gap semiconductor having a conductivity of a second polarity coupled in electrical contact with the first layer wherein the second polarity is different than the first polarity. The TVS assembly also includes a third layer of the first, the second, or a third wide band gap semiconductor having a conductivity of the first polarity coupled in electrical contact with the second layer. The layer having a conductivity of the second polarity is lightly doped relative to the layers having a conductivity of the first polarity.

    摘要： A system and method for measuring a thickness of a refractory wall of a gasifier using electromagnetic energy is disclosed. The system includes a waveguide with a bistatic or monostatic phased array antenna at one end. The waveguide is operably connected to a Network Analyzer that generates a pulse of electromagnetic energy with a desired bandwidth. The pulse is transmitted through a coaxial cable to the waveguide. The reflection of the pulse is received by the waveguide and input to a data acquisition system. An output device displays the resolvable discontinuities in impedance encountered by the pulse in its propagation path in the system

    摘要： A method is provided and includes exciting a sensor with an incident signal and generating a reflected signal by reflecting the incident signal from the sensor. The incident signal and the reflected signal interfere to form a standing wave. The method also includes processing the signals to determine a sensed parameter based upon a frequency at which the standing wave exhibits a null.
