Abstract: A brush roll configured to support a material web, in particular a web of corrugated board, comprises a roll core and arcuate shells, which are each arranged on the roll core and comprise bristles arranged on the outside. The brush roll further has fastening assemblies configured to fasten the arcuate shells to the roll core. Each of the fastening assemblies has a fastening body, which is locally fastened to the roll core, which locally fastens at least one of the arcuate shells to the roll core, which has a foot part, connected to the roll core, with a bottom, and a head part, connected to the foot part, with a lower side facing the roll core, said lower side forming at least one lower wedge face for engagement with at least one of the arcuate shells.

Abstract: An optoelectronic component includes an optoelectronic semiconductor chip and an optical element, wherein the optical element includes a prism structure configured to split light emitted by the semiconductor chip into two beams and deflect the beams in a first direction relative to one another, and the optical element includes a beam deflecting structure configured to deflect both beams jointly in a second direction perpendicular to the first direction.

Abstract: In an embodiment the optical component includes an optoelectronic semiconductor chip including a radiation emission face, a deflection element configured to deflect electromagnetic radiation emitted by the optoelectronic semiconductor chip in a main emission direction which forms an angle deviating from 90° with the radiation emission face, wherein the deflection element is configured as a prism structure and an optical lens having an optical axis, wherein the optical axis forms an angle deviating from 90° with the radiation emission face.

Abstract: A sensor that senses a biometric function includes at least one transmitter configured to transmit electromagnetic radiation in an emission direction, including at least one receiver configured to receive electromagnetic radiation in a receiving direction, wherein the transmitter and the receiver are configured such that the emission direction of the transmitter is inclined away from the receiving direction of the receiver by a defined angle, wherein the angle is 1° to 60°.
