Abstract: Method for replicating directional sound detecting a plurality of sound signals emitted by a sound source in a recording space and recording the plurality of detected sound signals emitted by the sound source. The method also configured for determining, in a time variable manner, a main direction of emission of the plurality of sound signals, and reproducing the plurality of sound signals based on the main direction of emission using a first reproduction unit associated with the sound source and at least one second reproduction unit spaced apart from the first reproduction unit. The main direction of emission is simulated in during the reproduction with the at least one second reproduction unit using time delays relative to the first reproduction unit.

Abstract: The invention relates to an assembly for carrying out a video conference between a location A and at least one location W, during which it is possible for at least some participants to make eye-to-eye contact or face-to-face contact. To achieve this, location A is equipped with at least two image generation elements for generating images of the participants in location A, said elements being assigned to different participant positions in location W and is also equipped with at least one optical representation of each participant position in location W.

Abstract: The invention relates to a method for recording sound signals of one or more sound sources located in a recording space and having time-variable directional characteristics and for reproducing the sound signals and directional information of the sound sources true to life in an area of reproduction. The invention also relates to a system for carrying out the method. In order to be able to record, transmit and reproduce the directional information of a sound source in real time, only the main direction of emission of the sound signal emitted by the sound source is detected in the recording space in a time-dependent manner and reproduction is carried out depending on the detected main direction of emission. In order to convey the directional information, the sound signals are reproduced by means of a first reproduction unit associated with the sound source and at least one second reproduction unit spaced apart from the first reproduction unit.

Abstract: The invention relates to a mirror (1), for use in optical imaging systems, whereby the mirror is connected at the edge thereof to a reinforcing element (3), at least partly surrounding the mirror and the reinforcing element also fixes the relative position of the mirror with regard to a further optical element (4). Positioning means (5) are arranged on the reinforcing element, cooperating with positioning means (7), arranged on further optical elements. The optical imaging system in particular concerns a telescope for optical transmission techniques.
