A retaining device for a sensor is mounted on a part having an opening, in particular, on an outer part of a motor vehicle. The retaining device includes an endplate attachable to an inner surface of the part and having an opening. The retaining device also includes a housing adjacent to the endplate for receiving at least part of the sensor. An additional member is mounted inside the opening in the endplate and includes a projection projecting outwards from the endplate. The additional member can be brought into engagement with the opening in the part such that the opening in the endplate is centrally aligned with respect to the opening in the part.

A method for controlling a wind turbine is provided. The method includes monitoring an electrical quantity at an output terminal of the wind turbine. The electric quantity has an amplitude and periodically varying with a grid frequency. The method further includes detecting an oscillation of the amplitude and decreasing active power output from the wind turbine at the output terminal depending on the detected oscillation.

A component for fabricating the electronic device comprises a substrate and a conductive film provided on the substrate, in which the adhesion of the conductive film to the substrate is not greater than 0.1 N / cm. The adhesion of the conductive film to the substrate is weak enough to enable the conductive film to be readily peeled from the substrate. This makes it possible to form a component on a substrate other than the substrate used during film formation, thereby greatly increasing the degree of product configuration freedom. If the adhesion of a lower conductive film on the substrate side is made to be not greater than 0.04 N / cm, it becomes very easy to peel the conductive film from the substrate.

Systems and methods are provided for determining optimized settings for a closed-loop stimulation system based on analyzing a phase response curve measured from electrophysiological activity, such as electrical nerve activity or electrical muscle activity. The slope of the phase response curve is computed and used to determine a phase window during which phasic burst stimulation should be provided to achieve a desired effect on oscillations in the subject. When the slope of the phase response curve is positive, a phasic burst stimulation applied during the phase window will decrease synchrony of the oscillations. When the slope of the phase response curve is negative, a phasic burst stimulation applied during the phase window will increase synchrony of the oscillations.

A method and a system are described for controlling an electrical machine in a drivetrain of a motor vehicle, the electrical machine being used as a drive unit for the motor vehicle. A pilot control unit determines a pilot control torque as a function of a predefined target torque of the electrical machine, the pilot control unit having a transfer function that corresponds to an oscillation component of a transfer function, ascertained in model-supported fashion for the overall drivetrain, that describes a dependence of a rotation speed of the electrical machine on a torque with which the electrical machine is operated. A control unit for the electrical machine determines a corrected target torque for the electrical machine by superimposing the pilot control torque on the predefined target torque and controlling the electrical machine as a function of the corrected target torque.

It is provided a radio oscillating system for oscillating a radio signal. The system has an optical modulator for oscillation, a modulating means for inputting a modulating signal of a frequency of fm into the optical modulator to modulate a carrier wave so as to interpose sideband waves onto the carrier wave at positions shifted with respect to the frequency of the carrier wave by the frequency “fm”; and an optical receiver for oscillation for receiving beam from the optical modulator and converting the beam into an electrical signal. The system further has a radiating means for radiating radio signal of a frequency of 2fm based on the electrical signal. An input voltage Vp-p applied on the optical modulator is 1.0 times or more and 1.99 times or less of a half-wavelength voltage Vπ of the optical modulator.

A voltage sensor includes an oscillator that has a circular or roughly circular shape and is supported by a mechanical support member, a fixed electrode that has a predetermined gap between the oscillator and the fixed electrode, and a drive electrode that is placed at a position different from the fixed electrode across the oscillator, and to which an AC drive voltage is applied to make the oscillator oscillate. In the voltage sensor, an electrostatic attractive force acts on the oscillator by applying a voltage to the fixed electrode, and a resonance frequency of the oscillator changes.
