    摘要: A method of determining and utilizing an Energy Efficiency Indicator, the method initiating with a step of determining a distal or angular offset between a pair of coupled shafts provided between adjacent rotating machines. The offset is correlated to energy efficiency between the pair of coupled shafts. Correlation is referred to as an Energy Efficiency Indicator (EEI). The Energy Efficiency Indicator (EEI) can be used to predict changes in alignment, changes in energy efficiency, and the like. Monitoring the coupled rotating machines and using the Energy Efficiency Indicator (EEI) can provide the operator with predictive information to enhance the reliability and extend the lifespan of the coupled rotating machines.

    摘要: Die Erfindung betrifft ein Verfahren und ein Messgerät (15), das zur Justage einer Lage eines Werkstücks (16) mit einer gekrümmt verlaufenden oberen Fläche (17) in Bezug auf eine Drehachse (C) des Messgerätes (15) eingerichtet ist. Das Werkstück (16) wird mit einem Werkstückträger (23) in eine erste Drehlage (c 1 ) gebracht. Innerhalb einer Messebene wird eine Mehrzahl von Messpunkten auf der oberen Fläche (17) aufgenommen. Das Werkstück (16) wird in eine weitere Drehlage (c 2 ) um die Drehachse (C) gebracht, und es werden erneut Messpunkte in der Messebene (E) auf der oberen Fläche (17) des Werkstücks (16) aufgenommen. Aus den aufgenommenen Messpunkten kann die Istlage (Li) des Werkstücks (16) sowie die Abweichung von der vorgegebenen Solllage (Ls) ermittelt werden. In der Solllage (Ls) wird die Symmetrieachse (A) des Werkstücks (16) in Übereinstimmung mit der Drehachse (C) gebracht. Hierfür werden Justageparameter, beispielsgemäß ein Kippwinkel (γ) und eine Verschiebung (t) ermittelt und eine Justageanordnung (24) des Messgerätes (15) abhängig von den berechneten Justageparametern angesteuert, um das Werkstück (16) zu justieren.

    摘要: The present disclosure relates to a method and apparatus for determining the misalignment between a device and a pedestrian, wherein the pedestrian can carry, hold, or use the device in different orientations in a constrained or unconstrained manner, and wherein the device comprises a sensor assembly. The sensors in the device may be for example, accelerometers, gyroscopes, magnetometers, barometer among others. The sensors have a corresponding frame for the sensors' axes. The misalignment between the device and the pedestrian means the misalignment between the frame of the sensor assembly in the device and the frame of the pedestrian. The present method and apparatus can work whether in the presence or in the absence of absolute navigational information updates (such as, for example, Global Navigation Satellite System (GNSS) or WiFi positioning).
