Abstract: The sound reproduction of a multichannel sound reproduction system with a plurality of speakers which is connected to the output of an FM stereo receiver is controlled by a control signal derived from the reception quality. Preferably, the control signal from the FM stereo receiver for controlling the stereo and mono components is also employed to control the multichannel sound reproduction system. For example, stereo, pseudo-stereo or mono reproduction are provided in the multichannel sound reproduction system in response to the stereo component within the output signal.

Abstract: A method for analyzing the identity, protein and/or peptide pattern and also the stability of samples containing physiologically acceptable enzyme mixtures with lipolytic, proteolytic and amylolytic activity, particularly mixtures of digestive enzymes such as pancreatin, for use in manufacturing medicinal products comprising such enzyme mixtures, e.g. precipitated pancreatin or pancreatin mini-microspheres.

Abstract: A radio signal receiver is tunable to a plurality of different reception frequencies and is set up to output a signal obtained from a radio signal received at a tuned frequency to a reproducer in an operating mode (S8), and to acquire information at least about the identity of a transmitter receivable at a given frequency in a standby mode (S2-S7), and to record said information in a memory. The receiver is set up, initially when switched on, to acquire and record (S3) information on a plurality of transmitters in a standby mode (S2-S7), before switching over to the operating mode (S8). The receiver may be operated together with a control unit which is coupled to at least one sensor and is set up to turn the receiver on and/or off depending on the detection result of the at least one sensor.
