Abstract: A device for guiding an airflow in a region of a roof opening in a motor vehicle roof comprises a wind deflector and at least one additional deflector. This additional deflector has a rear end face and is movably fastened to the wind deflector and adapted to protrude vertically upwards with respect to a rear edge of the wind deflector. The wind deflector and the additional deflector are each movable from a normal, unextended position into an extended position. The additional deflector is fastened to an underside of the wind deflector when in its normal position and moves along the rear end face of the wind deflector when moving into the extended position.

Abstract: A module, in particular a sliding roof module for a motor vehicle, comprises at least one guide, at least two carriages which are adapted to be moved in the guide and to which one component each is attached which is a component that is to be operated. The module further comprises at least a first catch which is connected with a drive device such that it can be shifted in the guide. The first catch and at least one of the carriages are designed such that the at least first catch can be coupled with one of the carriages and is able to shift it and, after a predetermined shifting of the carriage, can be detached from it.

Abstract: A mobile radio receiver, for example, a car radio, needs a circuit to detect and suppress adjacent-channel interference. This can be done by using bandpass filters (14) of differing bandwidth. The present invention dynamically adjusts bandwidth to an optimum value by continuously comparing (13) a first signal level, upstream of the bandpass filter, to a second signal level, downstream of the bandpass filter, to derive a difference value representative of adjacent-channel interference, then uses an electronically controlled selector switch (6) to select a particular filter (14.sub.N) whose bandwidth is sufficiently narrow to cut out the interfering broadcast signal. A table associating each magnitude range of interference with a particular filter bandwidth assures that bandwidth is broadened as interference diminishes, thereby assuring sufficient reception signal strength.
