Abstract: Various implementations include an apparatus for thermal processing of medical waste. The apparatus includes a body, a conductive heater, and an air flow device. The body portion defines a chamber for receiving two or more containers of medical waste. The chamber is in fluid communication with a gas processing device for biological materials. The conductive heater is thermally coupled to the chamber to provide heat to the two or more containers. The air flow device is configured to direct discharge gases from the two or more containers to the gas processing device.

Abstract: A method for turn fault detection in a multi-phase alternating current machine includes obtaining instantaneous line-to-neutral voltages from each phase of the machine, calculating the sum of the line-to-neutral voltages, and using the sum to determine whether a turn fault exists. The line-to-neutral voltages can be filtered to reduce harmonics. In one embodiment, deviations in a time-averaged function of the sum are examined. The time-averaged function can be exponentially weighted. Each of the line-to-neutral voltages can be calibrated to remove inherent machine phase impedance imbalance prior to calculating the sum of the line-to-neutral voltages.
