Abstract: 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.

Abstract: A device is described for igniting an air-fuel mixture in an internal combustion engine using a high-frequency electric power source having a coaxial waveguide structure (5) into which the high-frequency electric power may be coupled and whose one end protrudes into the individual combustion chamber of a cylinder of the internal combustion engine. The one end of the coaxial waveguide structure (5) is designed as an igniter (7a) in such a way that, when a voltage potential is applied, a field structure (22), protruding into the combustion chamber, and thus a free-standing plasma in the air-fuel mixture at the inner conductor (7, 7a), projecting from the waveguide structure, is generatable via an abrupt and/or smooth cross-section change (21) of the inner conductor (7) and/or the outer conductor (6).

Abstract: A device for the ignition of an air-fuel mixture in an internal combustion engine using a high-frequency electrical energy source. A coaxial waveguide structure forming a resonator chamber, into which the high-frequency electrical energy is able to be fed in a predefined coupling-in location at one end of an inner conductor of the waveguide structure. The coupling-in location is designed so that the inner conductor in the region of the coupling-in location is laterally opened out fanwise, and, in this context, a predefined length is continued coaxially between the outer wall and the coaxial waveguide structure and a feed line. Consequently, a feed line may be coupled on coaxially, using which the supply of the electrical energy takes place through a coaxial insulation in the outer wall of the waveguide structure into the resonator chamber.
