Abstract: A bed component, for example a mattress or a mattress base, includes a vacuum pump and at least one actuator which is adaptable in its height and/or firmness and has a maximum height in the non-actuated state, wherein the vacuum pump is fluidly connected to the actuator and a vacuum is formed in the actuator by the vacuum pump in the actuated state of the actuator and the height and/or firmness of the actuator is reduced, wherein the vacuum pump is provided in an area of the bed component external to the actuator. Further, a bed including a bed component is shown.

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.
