    摘要： A system includes a body, a sensor (50), a pressurized fluid source (46), and a blockage detection module (32). The body defines a cavity (44) open to an ambient environment at a port. The sensor communicates with the cavity to produce a signal representative of a fluid pressure within the cavity. The blockage detection module includes a pressure regulator (36) and a valve (38) disposed along a conduit (34) fluidly connecting the pressurized fluid source to the cavity. The blockage detection module includes a processor (40) and memory (42) encoded with instructions of a blockage detection method.

    摘要： Electronic circuits and methods sense an electromagnetic property of a target, and transmit data packets that encode the property along with diagnostic messages while avoiding data loss due to truncation at high sensing speeds. Data address bits may be used to split messages across multiple data packets. Data bits may be combined into a unified header that takes less time to transmit than in prior communication protocols. The transmission duration of each data bit may be lowered, thereby increasing throughput. The receiving system may synchronize its own operation against these shortened data bits, increasing its speed. Error packets may be sent between data packets, thereby reducing time to respond to faults in safety-critical systems. And additional current levels may be used to increase the data information rate.

    摘要： There is described a method of estimating a rotor speed in a wind turbine, the method comprising (a) obtaining measurement data indicative of structural vibrations within the wind turbine, (b) determining at least one harmonic vibration frequency based on the measurement data, and (c) estimating the rotor speed based on the at least one harmonic vibration frequency. Furthermore, a corresponding arrangement and a monitoring system for a wind turbine are described.

    摘要： Die Erfindung betrifft ein Verfahren zur Bestimmung von Anströmparametern eines Überschall-Flugkörpers, bei denen es sich um eine Machzahl, einen statischen Atmosphärendruck, einen globalen Anstellwinkel und einen Schiebewinkel handelt.
    In dem erfindungsgemäßen Verfahren erfolgt eine Druckmessung mittels mindestens vier Drucksensoren, die abseits einer Nase oder vorderen Stirnseite des Flugkörpers angeordnet sind und unterschiedliche Flächennormalen besitzen. Mittels der mindestens vier Druckmessungen erfolgt dann unter Verwendung einer Datenbank, einer Formel oder eines neuronalen Netzwerks die Ermittlung der vorgenannten Anströmparameter.
