Abstract: Capacitors and methods of making the same are provided. The capacitors may include a monolithic diamond body with electrodes of electrically conductive material therein. The electrodes of electrically conductive material may be separated by a dielectric diamond layer of the monolithic diamond body. The electrodes may be formed by ablating regions of the monolithic diamond body using a laser and introducing electrically conductive material into the ablated regions.

Abstract: A telemetry system is configured to monitor temperature of a wafer disposed in a vacuum. The system can include a plurality of sensors configured to measure temperature at a plurality of locations across the wafer. The system can further include a plurality of sensor signal conditioning circuits. Each sensor signal conditioning circuit can be coupled to a respective sensor of the plurality of sensors. The plurality of sensor signal conditioning circuits can be configured to convert a resistance from each sensor of the plurality of sensors into low frequency sinusoids that define a respective frequency that is proportional to the resistance. The system can further include a multiplexor configured to generate a composite modulating signal from the low frequency sinusoids. The system can further include a frequency modulation (FM) transmitter configured to send the composite modulating signal outside of the vacuum.

Abstract: A power substrate utilizing silver conductors on ceramic, and the process for making said device. The insulating portion of the substrate is fabricated from a ceramic by placing trenches into the ceramic which can be filled with silver conductors. These conductors can serve the purpose of traces for electrical interconnection, pads for die attachment, as well as thermal conductors for heat pipes and heat spreaders. The conductors can be made on both the top and the bottom of the ceramic. Such substrates may be used for a multitude of applications requiring power substrates for conducting large currents, and are suitable for high efficiency, high temperature, and/or high reliability applications.

Abstract: A turbine environment wireless transmitter for monitoring bearing health inside jet turbines. This transmitter has the ability to operate in 225 to 300 degree Celsius environments and monitor real time bearing temperature and vibration and transmit that data to a centralized system for processing. The system is powered by a built in thermal electric generator, which produces power in response to a thermal gradient across it. The information transmitted is used to monitor and diagnose a bearing operating parameters in real-time and predict a failure event before any damage occurs.

Abstract: A high temperature magnetic amplifier, which utilizes the nonlinear properties of square loop magnetic cores to achieve very large amounts of both voltage and power amplification. By combining square loop, grain-oriented magnetic materials with high temperatures along with high temperature packaging approaches, high temperature long lifetime components can be produced. The high temperature magnetic amplifier is used as a building block to develop high temperature versions of operational amplifiers, comparators, voltage regulators, timers, counters, modulators, motor starters, servo systems, converters, inverters, power switches and many other devices.
