摘要： A constant displacement ds of a capacitive actuator, for instance a capacitor for a fuel injection valve of an internal combustion engine, is obtained within a wide temperature range. While the actuator is being charged, its current and the voltage across the actuator are multiplied with one another. The product of the current and the voltage are integrated and the integration value is compared with a predetermined setpoint value. The process of charging is interrupted when the integration value reaches or exceeds the actual value. In an alternative embodiment, the actuator is charged from a constant current source and only the voltage drop is integrated.

摘要： An apparatus for driving a piezoelectrically controlled fuel injection valve includes a piezoelectric actuator having a discharging device and preferably a power MOSFET switch connected in parallel therewith. The discharging device is turned on by a monitoring device that is likewise connected in parallel with the piezoelectric actuator if an opening time of the piezoelectric actuator exceeds a predetermined monitoring time. The discharging device and the monitoring device are constructed as an integrated circuit (ASIC) and are integrated in a valve housing. A method for operating the apparatus is also provided.

摘要： In the illustrated embodiments, the signals to be transmitted are converted into electrical signals and are divided by means of filters into a plurality of frequency bands. The envelopes of the signals coming out of the filters are then employed for the modulation of tones. Finally, the original tones and the modulated tones are supplied to the hearing-impaired person as an audio signal. To this end, the disclosure provides that the original signal to be transmitted is transmitted together with the modulated tones, and that the ratio of the volumes of the original tones and those of the modulated tones is set to a ratio which is comfortable for the hearing-impaired person. The transmission of the modulated tones is at least partially interrupted for voiced sounds. Standard ear sets or implanted devices with direct electrical transmission of the signals to the auditory nerve can be employed for transmission to the hearing-impaired person. Disclosed methods and devices are particularly employable as a hearing aid for persons who are extremely hard of hearing or who have suffered total hearing loss.

摘要： An x-ray tube includes a vacuum housing. A cathode and an anode are disposed in the vacuum housing and insulated by at least one insulation element. Upon application of a high voltage, the cathode emits electrons that strike the anode as an electron beam. A voltage arrester device with an insulation path has a field strength that is higher than a field strength at the insulation element. If a voltage flashover occurs, the voltage is discharged via the voltage arrester device.
