Abstract: A device described here includes a housing and a multi-aperture imaging device. The multi-aperture imaging device includes an array of optical channels arranged next to one another and a beam-deflector for deflecting an optical path of the optical channels. In a first operating state of the device, the housing encloses a housing volume. In the first operating state of the device, the beam-deflector includes a first position within the housing volume. In a second operating state of the device, the beam-deflector includes a second position where the beam-deflector is arranged at least partly outside the housing volume.

Abstract: The invention relates to an optical microlens array and to a method for manufacturing an optical microlens arrays, wherein the method includes, among other things: providing a substrate having a first side and an opposite second side. The method further includes applying a photoresist to the first side of the substrate at least in portions, and structuring the photoresist such that the structured photoresist remains at predetermined locations on the first side of the substrate where one optical microlens each is to be later arranged. In addition, the method includes applying a hydrophobic coating to the first side of the substrate and subsequently removing the structured photoresist including the hydrophobic coating located thereon from the first side of the substrate. Furthermore, according to the invention, one microlens each is arranged on the spots of the first side of the substrate that are freed from the structured photoresist.

Abstract: There is provided a headphone or headset comprising at least one housing, at least one microphone for detecting interference sound, at least one active noise compensation unit for implementing active noise compensation based on the interference sound detected by the at least one microphone and for the output of a compensation signal. The headphone or the headset has at least one electroacoustic reproduction transducer for output of the compensation signal from the noise compensation unit and a circumaural cushion having a recess for receiving a spectacles side arm. The active noise compensation unit is adapted in noise compensation to take account of the effect of the recess in the ear cushion.

Abstract: There is provided a headphone or headset comprising at ;east one housing (150), at least one microphone (120, 130) for detecting interference sound, at least one active noise compensation unit (100) for implementing active noise compensation based on the interference sound detected by the at least one microphone (120, 130) and for the output of a compensation signal. The headphone or the headset has at least one electroacoustic reproduction transducer (140) for output of the compensation signal from the noise compensation unit (100) and a circumaural cushion (160) having a recess (161) for receiving a spectacles side arm (210). The active noise compensation unit (100) is adapted in noise compensation to take account of the effect of the recess (161) in the ear cushion.
