摘要： The invention relates to a personal information system, especially a personal guide system, for transmitting voice information of a speaker on wireless paths to a number of listeners. According to the invention, a voice recognition unit (SE) for identifying the source information of the speaker's source language, a translating unit (U) for translating source information into target information of the target language, and a voice generator unit (SG) for generating the target language from the target information are provided in the signal path between a microphone (M) of the speaker and the headphones (H) of the listeners.

摘要： The invention relates to a wireless microphone system. One aim of the invention is to further develop such wireless microphone systems while another aim thereof is to improve the intermodulation distance between HF transmitters so as to allow a greater number of transmitters to be used in the same frequency band. Said aim is achieved by a wireless microphone system comprising antennas that are connected thereto, a circulator and/or an HF isolator being connected to the antennas or antenna.

摘要： The invention concerns a method for the reproduction of audio sound using ultrasound loudspeakers as well as a construction type of the loudspeakers and their application. A method and device for the reproduction of audio sound using an ultrasound generating device, whereby the audio signal to be reproduced is connected to the ultrasound frequency range via side-band amplitude modulation with a carrier signal in the ultrasound frequency range and whereby means are also provided to subject the ultrasound signal to dynamic error compensation. The compensated ultrasound signal is, if necessary, subjected to a frequency response linearisation procedure and then fed to an ultrasound convertor (loudspeaker), whereby means are provided for reducing the amplitude of the ultrasound carrier signal, (carrier reduction).

摘要： A headphone (K) is provided with an active noise compensation unit (ASK) for the compensation of interfering noise. The headphone further comprises a wireless receiver (I) for the wireless receiving of an audio signal for reproduction. The provision of the wireless receiver (I) permits the direct and intentional transmission of information or audio signals to the support of the headphone (K) without said signals being removed by compensation by the noise compensation unit (ASK).

摘要： The invention relates to an arrangement for the optical distance determination of a reflecting surface, which can especially be used to determine small distance modifications, such as those that frequently occur in oscillating systems. One such arrangement can also be used as an optical microphone or hydrophone. The inventive arrangement is designed in such a way that light from a light source is directed towards a reflecting surface (4) by means of a first optical wave guide, and light reflected from the reflecting surface is directed towards at least one statically arranged optical detector by means of the first optical wave guide or at least one other optical wave guide. An optical element (2) collimating in the direction of the reflecting surface is arranged between the reflecting surface and the at least one optical wave guide. Furthermore, at least two optical elements (3) focussing in the direction of the reflecting surface are arranged above the reflecting surface, the optical axes of said optical elements being parallel to the optical axis of the collimating optical element and arranged at constant distances from each other.
