Abstract: Disclosed herein are system, method, and computer readable medium embodiments for machine learning systems to process interactive communications between at least two participants. Speech and text within the interactive communications are analyzed using machine learning models to infer insights located within the interactive communications. The inferred insights are converted to descriptive text or audio and tagged to the interactive communication as graphics or audio whispers reflecting the insights added to the interactive communication.

Abstract: Systems and methods for voltage regulation of high voltage direct current systems are provided. In certain embodiments, a system includes a generator that generates alternating current (AC) voltage. The system further includes a power converter that converts the AC voltage into regulated direct current (DC) voltage. Also, the system includes a voltage regulator. In additional embodiments, the voltage regulator includes an AC voltage regulator that regulates the AC voltage generated by the generator. Also, the voltage regulator includes a DC voltage regulator that regulates the DC voltage produced by the power converter. Moreover, the voltage regulator includes a regulator selector that selectively activates one of the AC voltage regulator and the DC voltage regulator based on a current from the power converter and at least one of a voltage of the generator and a voltage of the power converter.

Abstract: An electric machine includes a fluid control system that is configured to regulate the flow rate of fluid to the electric machine. The machine includes a sensor that senses a parameter representative of cooling required by the machine. The sensor supplies a sensor signal to a control unit, which in turn supplies a flow control signal to a flow regulator. The flow regulator, in response to the flow control signal, controls the flow rate of fluid to the machine to what is needed for effective cooling at current operating conditions. As a result, windage losses and pumping power requirements in the machine are reduced, and machine efficiency is increased.
