Abstract: The invention relates to control of a wind turbine comprising a plurality of multi-axial accelerometers mounted at different positions in the nacelle and/or in a top portion of the tower. The position and orientation of each accelerometer as mounted is obtained, accelerations in at least two different directions by each accelerometer are measured during operation of the wind turbine. From a number of predetermined mode shapes for the movement of the wind turbine is then determined an absolute position of at least one of the accelerometers during operation of the wind turbine based on the measured accelerations, the mount position and orientation of each accelerometer and the pre-determined mode shapes. Hereby a more precise absolute position during operation is obtained which can be used in the controlling of the turbine.

Abstract: An approach to intelligent additive manufacturing makes use of one or more of machine learning, feedback using machine vision, and determination of machine state. In some examples, a machine learning transformation receives data representing a partially fabricated object and a model of an additional part (e.g., layer) of the part, and produces a modified model that is provided to a printer. The machine learning predistorter can compensate for imperfections in the partially fabricated object as well as non-ideal characteristics of the printer, thereby achieving high accuracy.

Abstract: A power-distribution system can detect a transmission-line electrical fault, and the power source can be electrically isolated from the transmission line before a human or equipment is substantially harmed or damaged. A controller on the source side is responsive to one or more sensors that provide a signal indicative of the voltage across the transmitter side of the transmission line.

The controller determines the normal impedance of the transmission line from measurement and detects a transmission-line fault, as indicated by a change in carrier waveform reflections or energy content of the carrier waveform and generates a command to open the source-disconnect device upon detection of the fault.
