Abstract: A method selects a communication status for a first mobile terminal. The first mobile terminal assumes a “slave” status during a first time period and waits to see whether, by a communication request from another mobile terminal to the first mobile terminal, a connection is set up to the other mobile terminal. If a connection is set up, the first mobile terminal constantly assumes the “slave” status and the other mobile terminal constantly assumes a “master” status. After the first time period without a communication request from another mobile terminal, the first mobile terminal switches from the “slave” status to the “master” status for a second time period and sends a number of communication requests to set up a connection to another mobile terminal and, if a connection is set up in this way, constantly assumes the “master” status and the other mobile terminal constantly assumes the “slave” status.

Abstract: A method operates a hearing device system that contains a hearing device and a database system, which is separate from the hearing device and is set up for communication with the hearing device. The method includes ascertaining a piece of location information for a current position of the hearing device and the location information is transmitted to the database. The database then ascertains whether an electronic device that is separate from the hearing device is situated at a prescribed physical distance from the hearing device. The presence of the separate electronic device within the prescribed physical distance is taken as a basis by the database system for creating for the hearing device a parameter set that contains a number of parameters pertaining to the signal processing of audible signals in the hearing device. This parameter set is used by the hearing device for the purpose of signal processing.

Abstract: A hearing device system includes a hearing device with a microphone, with a signal processing unit and with a loudspeaker connected to the signal processing unit, and a voice communication device coupled to the hearing device. A control unit which is integrated in the hearing device operates the system in different modes of operation. At least one device senses a distance between the voice communication device and the hearing device and the control unit operates the hearing device system in a first mode of operation when the distance is relatively short and in a second mode of operation when the distance is relatively greater. There is also described a method for operating the hearing device system.

Abstract: In a method for signal processing in a hearing device, an acoustic noise signal is received by a microphone of the hearing device and processed by a signal processing unit of the hearing device for output to a hearing device user. An electromagnetic information signal is received by a receiving unit of the hearing device. From this information signal, a piece of information about an acoustic interference signal which is contained in the acoustic noise signal is derived. This piece of information is taken into account during the processing of the acoustic noise signal for reducing the acoustic interference signal.

Abstract: Disclosed are a method and arrangement for embedding data (dn) in a host signal (xn) using dithered quantization index modulation (71), and extracting said data from the watermarked signal. A problem of this embedding scheme (71) is that the amplitude of the watermarked signal (sn) may have been scaled (72) unintentionally (by a communication channel) or intentionally (by a hacker). This causes the quantization step size (?r) of the received signal (rn) to be unknown to the extractor (73) which is essential for reliable data extraction. The invention provides making a histogram (74) of those signal samples that have substantially the same amount of dither, and analyzing said histogram to derive an estimation of the step size (?r) therefrom. In a preferred embodiment, a pilot sequence of predetermined data symbols (dpilot) is embedded (76) in selected (S) samples of the host signal.
