Abstract: The disclosure relates to a packaging system comprising a deep-drawing packaging machine configured to produce packages in a production direction, and a feeding system for the deep-drawing packaging machine, wherein the feeding system comprises at least one transport belt device configured to transport cardboard blanks in a transport direction extending transversely to the production direction of the deep-drawing packaging machine into a transfer area formed within a machine frame of the deep-drawing packaging machine, and wherein the feeding system comprises a lifting device arranged in the transfer area for collecting and lifting the cardboard blanks transported into the transfer area by means of the transport belt device, wherein the lifting device has a plurality of independently controllable lifting units positioned one behind the other in the transport direction. Furthermore, the disclosure relates to a corresponding method.

Abstract: A coffee machine, a coffee bean container, and a system including a coffee machine and a coffee bean container are described. The coffee bean container has an identification element that is read by the coffee machine when the coffee bean container is placed on the coffee machine. Based on the information read from the identification element, a parameter set is applied to the coffee machine and the coffee machine is individually adjusted for the coffee bean container placed on it.

Abstract: An optical cable includes an optical fiber having a fiber core and a fiber cladding, and an output coupling plug at an output coupling-side fiber end of the optical fiber. The output coupling plug comprises at least one cladding light sensor arranged behind the output coupling-side fiber end and configured to measure cladding light that exits frontally from the fiber cladding at the output coupling-side fiber end.

Abstract: An apparatus for coupling out radiation from an optical fiber, includes a housing, and a stop having a stop opening for delimiting an output coupling angle of radiation that is coupled out of an output end of the optical fiber to a maximum output coupling angle with respect to a central axis of the stop opening, wherein the stop is arranged in the housing. The stop has a stop body made from a transparent material, the stop body has a first total internal reflection face for reflecting radiation that is coupled out of the output end of the optical fiber with greater output coupling angles than the maximum output coupling angle, and the stop body has a second total internal reflection face for reflecting radiation that propagates opposite to the radiation coupled out of the output end and is reflected back by a workpiece.
