摘要： A local coil system for detecting magnetic resonance (MR) signals in a magnetic resonance tomography (MRT) device includes an energy reception antenna for inductively receiving energy for the local coil system from a magnetic field changing over time with an energy transmission frequency. The energy reception antenna includes a conductor loop running in loop-like fashion from a first loop connection to a second loop connection. At least one path filter that blocks for harmonic frequencies of the energy transmission frequency is arranged over the course of the energy reception path, and/or at least one path filter that blocks for harmonic frequencies of the energy transmission frequency is arranged over the course of an energy reception path leading from the loop connections to a rectifier.

摘要： The method serves to determine the vibrational state of turbine blades, arranged on a rotor shaft, mounted such as to rotate in a housing and/or of guide vanes. At least one electromagnetic wave is transmitted into a flow channel in the vicinity of the blades, using means for the generation of at least one electromagnetic wave. The electromagnetic waves are at least partly reflected from at least one blade. The reflected part of the at least one electromagnetic wave is received by means for receiving and the vibrational state of the corresponding blade is determined from a signal corresponding to the at least one received electromagnetic wave.

摘要： The present embodiments relate to a balanced-to-unbalanced transformer for converting a symmetrical high-frequency signal into an asymmetrical high-frequency signal. The balanced-to-unbalanced transformer includes two coil windings made of wire. The two coil windings are electrically insulated from each other and are wound on a winding form. Each of the two coil windings has an input at one end of the winding form for the symmetrical high-frequency signal and an output at another end of the winding form for the asymmetrical high-frequency signal. The two coil windings lie on top of one another in a radial direction of the winding form.
