Abstract: A brewing system includes a brewing apparatus and a capsule containing a substance for brewing. The capsule has an opening on one side and a base on an opposite side. The base includes a light input surface, a light-output surface and a light conductor to conduct light from the light input surface to the light output surface. The apparatus includes: a brewing chamber including an inlet for heated water, an outlet for the brewed beverage, and an opening in communication with the opening of the capsule. A light source on the brewing apparatus emits light into the base via the light inlet surface of the capsule. The light conductor conducts the light to the light-output surface. A light detector of the brewing apparatus detects light emitted by light-output surface on the base of the capsule. A method of operating the brewing system and a capsule system are also described.

Abstract: A device for coupling light into an optical conductor has an optical light element, preferably having an LED, for generating light. The optical light element has a light-guiding body with a luminous surface and forms a housing and in which a photoelectric material is disposed in a reflector. An optical conductor is provided and has a light-receiving surface onto which the light can be projected. The luminous surface has a coupling region corresponding directly to the receiving surface of the optical conductor and which is free from additional optical elements. The reflecting surface of the reflector focuses the light onto the coupling region of the luminous surface and/or onto the receiving surface of the optical conductor. Therefore, the light emitted by the photoelectric material is radiated only onto the coupling region and the coupling efficiency is increased, and it is possible to use cost-effective optical conductors of small diameter.

Abstract: A display device has a fiber optic projector for the luminous display of graphical representations. The projector has a fiber optic component with a projector input connected via optical conductors to a projector output. The projector input receives an input image that is transmitted to the projector output through optical conductors, for display as an output image with a display unit. Instead of sorting the optical conductor ends and combining them in a corresponding arrangement with identical assignment at the input and output sides, they are rather arbitrarily positioned such that the ends are irregular at the input as compared to the output. That is, the projector input and projector output are formed by combined optical conductor ends situated respectively opposite one another, that the optical conductor ends on the input and/or output sides are assigned to one another irregularly.
