    摘要： A control device includes a magnetic actuator, a final control element, a regulating unit and a measuring device. The magnetic actuator has a coil, a core, and an armature. The actuator is connected to the final control element. The measuring device determines an inductance value L of the coil and generates, as a function of the inductance value L, a first control signal by which a theoretical value of the amplitude of the current through the coil is changed to a holding value. When a pulse signal P is present, the current through the coil is regulated to the theoretical value by the regulating unit.

    摘要： A process for selective graphic representation and/or evaluation of the Doppler spectrum of objects limitedly resistant to sonic intensity, for example biological organs and tissues, by an ultrasonic process wherein a material is introduced in the examination area to be acoustically irradiated, nonlinear oscillations are produced in the examination area by irradiated ultrasonic waves and the signal is evaluated by an ultrasonic converter. Also, a circuit for carrying out the above process is disclosed.

    摘要： In the exemplary embodiments, the sound signals are converted into electrical signals, which are wirelessly transmitted to an implanted receiver, and from the latter, electric stimuli in electrode channels are brought to act on the auditory nerve. The transmission proceeds in the time division multiplex technique in such a manner that the electrical signals are subjected to a pulse modulation and are transmitted in an HF-channel. Thus, the receiver can be reduced with regard to the volume of its construction as well as with regard to its energy requirement. The disclosed method and hearing prostheses for its realization are particularly suited for attending to the needs of the extremely hard of hearing.

    摘要： An X-ray tube includes a vacuum-filled housing and an anode contained in the vacuum-filled housing. The anode is operable to produce an X-ray beam based on electrons emitted from a cathode and attracted by a high voltage applied to the anode. The X-ray tube also includes a high-voltage power line introduced from an external side of the housing for supplying the anode with a high-voltage potential. The X-ray tube includes an electrical feed for electrically insulating the high-voltage power line from the housing. The electrical feed in the X-ray tube includes at least two insulating layers radially between the high-voltage power line and the housing. The at least two insulating layers are separated from one another by a metallic coating.
