摘要:
Wireless microphone systems are used, for example, in theater, stage performances, television, broadcast radio or in concerts to amplify voices or instruments for a large audience. Due to the plurality of actors or musicians, a corresponding number of audio channels is required to transmit the audio information. 20 to 50 audio channels can thus be required in a parallel mode even in common applications. The invention relates to a network system (1) for audio equipment (4) having a plurality of base stations (3) and having a plurality of microphone modules (4) wherein the microphone modules (4) are and/or can be allocated to the base stations (3) via configuration data and wherein each microphone module (4) of a microphone-module-base-station allocation is designed to transmit audio information on a transmitting frequency F1, F2, F3, F4, FX, FY to the allocated base station (3) of the same microphone-module-base-station allocation, wherein the base stations (3) are networked to one another such that the configuration data are interchangeable, having a control device (2), wherein the control device (2) is designed in respect of programming technology and/or circuit technology to automatically adapt the configuration data of the base stations (3) and/or microphone modules (4) and/or microphone-module-base-station allocations. The control device (2) is designed to adapt the configuration data in consideration of measured and/or calculated interactions of the microphone-module-base-station allocations and/or in consideration of the intended use of the respective microphone module (4).

The present invention provides a toll collection device for a motor vehicle with an anti-theft device and a method for operating such a toll collection device for a motor vehicle. The toll collection device has a locating device, an anti-theft device, and a transfer device. The locating device is suitable for determining a global position of the motor vehicle and providing global position information depending thereon. The anti-theft device has a first means, a second means and a third means. The first means is suitable for providing the currently provided global position information as reference position information when the motor vehicle is in the off mode. The second means is suitable for comparing the respective currently provided global position information to the provided reference position information in respectively preset time intervals and providing position-changing information depending thereon. The third means is suitable for generating an alarm signal as a function of the off mode of the motor vehicle and the provided position-changing information. The transfer device is also equipped to transfer the generated alarm signal to at least one receiver arranged outside the motor vehicle.

摘要:
Microphone systems having wireless microphones are often used in events such as discussions, concerts, plays, etc. and normally have a plurality of wireless microphones which are worn by users, such as actors, musicians, singers, etc, and one or more receiving stations which receive the audio signals of the wireless microphones and forward said signals to mixing consoles, amplification systems, recording devices, etc. In addition to the basic functionality of transmitting audio signals, microphone systems have become known which implement additional functions. The invention relates to a microphone module 2 having a transmitting unit 6 wherein the transmitting unit 6 is designed for the wireless transmission of audio information to a base station 3, having a receiving unit 8, wherein the receiving unit 8 is designed to receive wirelessly transmitted status information and/or messages from a transmitter 4, 12 and having an output device 13, 14 for the output of the status information and/or messages to a user of the microphone module 2.

The present invention relates to a phase correction device (12) for a signal which has a plurality of signal components which are each modulated onto a carrier signal, said signal having been sampled before transmission in a transmitting apparatus at a transmission sampling clock rate which has a transmission sampling clock duration, and having been sampled after reception in a receiving apparatus with a reception sampling clock rate which has a reception sampling clock duration, with each carrier signal having an associated carrier frequency. In order to carry out phase correction particularly efficiently, the phase correction device (12) is designed to in each case vary, by an associated phase angle, the phases of the signal components as a function of the ratio of the transmission sampling clock duration to the reception sampling clock duration.

The invention relates to a receive circuit (1) for receiving an OFDM signal comprising successive frames with a number of OFDM symbols, said OFDM symbols being composed of a useful interval (Tu) containing user data and a guard interval (Tguard) to separate the useful intervals (Tu) of the OFDM symbols from each other. The inventive receive circuit is provided with an input circuit (3) for converting the frequency of the OFDM signal in order to obtain an intermediate signal, an evaluation unit (24) for defining successive time slots and evaluating the OFDM symbols in said time slots, a digitally adjustable amplifier unit (10, 16), and an amplifier controller (6) for adjusting the amplification of the amplifier unit (10, 16) in order for the signal level of the intermediate signals to lie within a predetermined signal level range. The disclosed receive circuit (1) is characterized by a control unit (20) which is connected to the amplifier controller (6) in such a way that the amplification of the amplifier unit (10, 16) is adjusted at one or several points in time lying outside the time slots.
