Disclosed is a method for monitoring the operation of a drive component. In order to minimize additional hardware complexity, the monitoring method is cared out by a coil that is integrated in a mobile terminal by acquiring an electromagnetic variable of the drive component outside a housing of the drive component by the integrated coil, determining at least one first frequency based on the acquired electromagnetic variable, and determining a first status variable of the drive component from the at least one first frequency.

A stator for an electrical rotating machine includes a laminated core having coil bars and a winding head board resting on an end side of the laminated core and having a main body including a first dielectric material. Conductor tracks are connected to the coil bars and integrated into the winding head board. The winding head board has a region with a second dielectric material and/or a region with a third dielectric material, with the second dielectric material having a higher thermal conductivity than the first dielectric material. The region with the second dielectric material is arranged between a conductor track and the laminated core such that heat is transmittable between conductor track and laminated core via the second dielectric material. The third dielectric material has a higher dielectric strength than the first dielectric material, with the region with the third dielectric material arranged between at least two conductor tracks.

A symmetrical input signal is converted into an asymmetrical output signal. A first conduction path and a second conduction path are arranged parallel to one another based on signal flow. The first conduction path and the second conduction path form a first stage and a second stage. The first conduction path includes a first high-pass element assigned to the first stage. The second conduction path includes a first low-pass element assigned to the first stage. The first conduction path and the second conduction path have a second high-pass element assigned to the second stage. The second conduction path includes a second low-pass element assigned to the second stage and arranged in a chain with the first low-pass element. Each high-pass element shifts the phase of a signal forward, and each low-pass element shifts the phase of a signal backward to generate the asymmetrical signal.

The invention relates to an arrangement and a method for the galvanically separated energy transmission, in which the energy is transmitted via a dielectric waveguide.

Arrangement and method for the galvanically separated energy transmission

A facility is provided for the wireless resonant charging of rechargeable hearing instruments. The hearing instrument is freely positionable in a charging device for charging purposes. The charging device for the wireless charging has a transmit antenna arrangement, a transmit amplifier for actuating the transmit antenna arrangement and a charging space. The transmit antenna arrangement has two feeding points, which are spatially arranged in relation to the charging space such that a circularly polarized electromagnetic field can thus be generated in the charging space. The transmit amplifier actuates the antennas accordingly to generate a circularly polarized electromagnetic field in the charging space. In the process a coil arrangement generates a circularly polarized HF field. A good resonant coupling, even with a tilted hearing instrument, is possible, in other words with an undetermined and unpredictable orientation and position of the receive coil of the hearing instrument.

Wireless charging system for hearing instruments

To make the charging of hearing aids more convenient, a charging device for wirelessly charging a hearing aid is provided. The charging device has a cylindrical container, an integrated antenna for generating an alternating magnetic field in the container in the event of electrical excitation, and a charging circuit which can be used to electrically excite the antenna. The antenna is a birdcage antenna in which rods are arranged parallel to a cylinder axis on a cylinder jacket and the ends of the rods at the edges of the cylinder jacket are each connected to an end ring. A switching element is arranged in each of the rods. The charging circuit is used to alternately generate a circular magnetic field, in which case the switching elements are operated in a closed mode, and a linear magnetic field, in which case the switching elements are operated in an open mode.

Shielding for an electronic circuit includes at least one substrate. A metal structure is disposed on at least one side of the at least one substrate. The metal structure includes a number of non-contiguous part areas. Adjacent part areas that are disposed on a same side of the substrate are spaced apart from one another by a boundary line running in a serpentine shape.

Shielding for an electronic circuit

A hearing instrument system with a rechargeable battery or accumulator is optimized for everyday use, in particular for EOL detection, and the performance and service life of the accumulator. A hearing instrument, an accumulator system, and a charging system each have an energy transfer interface and a communication interface. The energy transfer interface and communication interface on the accumulator side can establish an energy transfer link and/or communication link on the charge and hearing instrument side. The accumulator system provides energy to the hearing instrument and transmits state of charge information generated by an accumulator control facility to the hearing instrument by way of the respective communication link. The transmission of the state of charge information enables a reliable state of charge detection in the case of batteries, whose state of charge cannot be identified on their voltage, for instance Li-ion systems with closed-loop controlled voltage.
