Abstract: Thus there is provided a microphone (10) having a first end (12) with a first slip ring (100) which is divided into at least first and second segments (GND, 300). The first slip ring (100) co-operates with a microphone head (12) when the microphone head (12) is fastened to the first end (12) of the microphone by means of a screw connection. The microphone further has a detection unit (16) coupled to the at least first and second segments (GND, 300) of the first slip ring (100) to detect rotation of the microphone head (12).

Abstract: The invention relates to a process for the transmission of digitized audio information of high quality and with a short delay, in particular processes for the transmission of digitized audio information in an audio pickup (microphone) and/or playback path. According to the invention there is proposed a channel filter which is used to shape the high frequency spectrum of the transmission, wherein the spectrum has no attenuation in a first range of about 100 to 300 kHz useful bandwidth and in a range outside the first range it has a stop-band attenuation of particularly preferably more than 60 dB or more than 80 dB.

Abstract: There is provided an antenna unit comprising an antenna element and at least one high-dielectric supplemental element disposed in the proximity of the antenna element.
