摘要： An induction pressing plate type real-time monitoring apparatus, including a fixing portion, an abutting portion, and an inductor. The fixing portion has a hole for fixing and connecting a fastener to an upper or lower platform of a forming device. The abutting portion is connected to the fixing portion, and the abutting portion in at least part of a pressure surface region is configured to press a tested piece to be induced. The inductor is disposed at the abutting portion, and has an induction unit for inducing actual information transmitted to the abutting portion by the direct contact of the tested piece and converting the actual information into measurable data, an output unit for outputting the data, and a power supply unit for providing power to the induction unit and the output unit.

摘要： A condition monitoring system for a wind turbine generator includes an orientation sensor installed in a nacelle and configured to detect an orientation of the nacelle and a condition monitoring unit configured to receive an output from the orientation sensor and perform at least any one of recording, analysis, or transmission of a signal. The condition monitoring unit preferably detects, based on the output from the orientation sensor, the movement along the rotation direction of the nacelle associated with a torsional oscillation of the tower. The orientation sensor can also detect slow directional fluctuations that are difficult to detect using an acceleration sensor or the like, and thus, can satisfactorily detect the rotation of the nacelle associated with the torsional oscillation of the tower.

摘要： The present invention relates to a vector sensor for measuring particle movement in a medium. The vector sensor comprises a magnetic body that is held at a certain distance from a magnetometer in such a way that the magnetic body can move in time with a passing particle movement, wherein the magnetometer is arranged to detect the oscillations in the magnetic field that the movements in the medium produce.

摘要： The present invention is an extremely low frequency (ELF) microphone and acoustic measurement system capable of infrasound detection in a portable and easily deployable form factor. In one embodiment of the invention, an extremely low frequency electret microphone comprises a membrane, a backplate, and a backchamber. The backchamber is sealed to allow substantially no air exchange between the backchamber and outside the microphone. Compliance of the membrane may be less than ambient air compliance. The backplate may define a plurality of holes and a slot may be defined between an outer diameter of the backplate and an inner wall of the microphone. The locations and sizes of the holes, the size of the slot, and the volume of the backchamber may be selected such that membrane motion is substantially critically damped.

摘要： Exemplary embodiments provide a surface of a rotating element with both a phase reference mark and a plurality of additional marks. A proximity probe detects the passage of both the phase reference mark and the plurality of additional marks as they rotate through a detection zone. Both a phase reference signal and a vibration reference signal are generated, which signals are used to calculate lateral and angular (and optionally torsional) vibration of the rotating elements.
