For a set-up for measuring a rotational speed of a turbocharger of a motor vehicle, including at least one antenna for generating and/or receiving electromagnetic radiation and an electronic module having at least one electric and/or electronic component and being electrically connected to the antenna. The set-up further includes a housing shell made at least partially of laser-absorbing material and having an inner chamber, and a housing cover, which rests on at least one laser-absorbing contact surface of the housing shell and covers the inner chamber of the housing shell at least partially, and at least sections of which are made of material transparent to laser radiation; the antenna and the electronic module being situated in the inner chamber of the housing shell, and at least sections of the housing cover being welded to the housing shell at the at least one contact surface using a laser-welded seam.

A communications system for a battery-management system of a battery includes coupling networks that are each connected or connectable via two input-side connections to a transmission channel, and via two output-side connections to a respective one of a plurality of communications users. The transmission channel can be used for the transmission of communications signals at a transmission frequency and that are to be transmitted and/or received by the communications users during a communications process between the communications users. At least one of the coupling networks has a first and second operating state, in which an input impedance that occurs between the two input-side connections of the respective predefined coupling network at the transmission frequency has two different impedance amounts. A communications user allocated to a predefined coupling network can set the allocated predefined coupling network to each of its two operating states once or multiple times during the communications process.

A method and a device for adaptively controlling power in a radar device having a radar transmitter and a radar receiver are provided, in particular for applications in vehicles. The radar signals are emitted, and radar signals reflected off of target objects are received and checked for irregularities. The transmitting power of the radar transmitter is reduced when irregularities occur which are attributable to interference caused by neighboring radar transmitters.

Method and device for the adaptive regulation of power

The present invention relates to a method for sensing information about the position and/or movements of the body of a living being or a part of the body inside the body, in particular for use in a motor vehicle. The method includes the steps:
