Abstract: An arrangement and a method for automatically controlling the volume in an audio signal reproduction device. A digital signal processing circuit, which is arranged in the audio signal path for influencing the audio signal anyway, is used to reduce the reproduction volume in the event of an overdrive condition of the power amplifier. The overdrive condition is indicated by an overdrive signal attained by the power amplifier. In the process, the decrease and increase in the volume is carried out using various time constants, and disturbing control oscillations are neutralized by inserting a counter which must be decremented prior to a raising of the volume.

Abstract: A method of use provides an extremely efficient manner of ordering a radio program occurring at approximately the time presented, minimizing the need to remember any details. The method is embodied in a range of tactile and voice controls which people in motion need to have. Security options include voice signatures, button sequences and fingerprint identification. User feedback is embodied in both audio and visual display formats. A method of controlling a radio is claimed which provides for placing an order, querying the ordering system for additional information, initializing a user's identifying signature, initializing a session by identifying a user, if the user is not properly identified, blocking access to ordering, and in certain embodiments, calling the police. A radio device is claimed supporting an IF signal source containing essential information on the radio program, an embedded controller, user interface as well as a radio transceiver by which the ordering transaction is carried out.

Abstract: A receiver receives FM multiplex broadcast data of both RDS and DARC systems by using one front end. A BIC detection circuit (101) detects a block identification code (BIC) included in received data. A coincidence/non-coincidence detection circuit (104) judges whether or not a BIC detection timing is correct and emits a coincidence/non-coincidence pulse. A forward protection circuit (106) counts a frequency of outputs of non-coincidence pulses and retains an established synchronous condition until the counted value exceeds a predetermined value. Then, a forward protection control circuit (108) inhibits the forward protection circuit from performing a count operation while a search is performed for selecting a station. Also, a rearward protection circuit (105) counts a frequency of outputs of coincidence pulses and establishes a synchronous condition when the counted value reaches a predetermined value. Further, a rearward protection control circuit (800) inhibits the rearward protection circuit from performing a count operation while a search is performed.

Abstract: A method and apparatus for operating a radio reception system, which comprises a plurality of receivers assigned to a common output device, in which one of the receivers is designated as audio receiver and is tuned to a frequency of a radio transmitter, and outputs a signal received from the transmitter to the output device. At least one second receiver is designated as search receiver, and continuously searches its own reception frequency band for a frequency of the same transmitter. The system changes to a frequency of this transmitter, which was found by the search receiver, if the quality of the signal received by the audio receiver falls below a certain limit.
