Abstract: A beverage preparation machine (1) comprising a brewing unit (3) having a brewing chamber (10), the brewing chamber (10) having an inlet (23), an outlet and at least one further access (25) for flushing the brewing chamber (10). The beverage preparation machine (1) further comprises a pump (4) for delivering an extraction or rinsing liquid, a first fluid line (49) between the pump (4) and the inlet (23) with a first valve (50), a second fluid line (51) between the pump (4) and the further access (25) with a second valve (52), and a control (5) for controlling at least one of the valves (50, 52) and/or the pump (4).

Abstract: Brewing chamber half (11, 12) for forming a brewing chamber (10) with a corresponding second brewing chamber half (12, 11) of a brewing unit (3) of a beverage preparation machine, the brewing chamber half (11, 12) having an inlet (23) for introducing a brewing liquid for preparing a beverage and/or an outlet (24) for discharging a prepared beverage. The brewing chamber half (11, 12) has at least one further access (25) for the introduction and/or discharge of a rinsing liquid.

Abstract: Brewing unit of a beverage preparation machine with a brewing chamber (10) and a brewing chamber surface (15), wherein the brewing chamber (10) is designed to be substantially rotationally symmetrical with respect to an axis (16) directed from a first brewing chamber half (11) to a second brewing chamber half (12). The brewing chamber (10) has a maximum axial extension (17) in the direction of the axis (16), which is smaller than the largest diameter (18) transverse to the axis (16). Furthermore, the brewing chamber (10) has a thickness (19) in the area of the axis (16) which is equal to or smaller than the axial expansion (17).

Abstract: Brewing unit (3) for a beverage preparation machine with a first brewing chamber half (11) and a second brewing chamber half (12), which are arranged to be movable relative to one another from a closed position for forming a closed brewing chamber into an open position in which a capsule (60) can be inserted into the brewing chamber. The brewing unit (3) has at least one, preferably two, holding means (38) which hold a capsule (60) in an intermediate position in the open position between the first and second brewing chamber halves (11, 12) when the capsule (60) is inserted and release it when the brewing chamber is closed. Before release by the holding means (38), the first and second brewing chamber halves (11, 12) are spaced apart in such a way that the brewing chamber halves (11, 12) cannot grip a capsule (60).

Abstract: A radio transmitting device configured to transmit a spread-spectrum radio signal wherein a carrier frequency changes in a predetermined set of radio channels according to a hopping sequence, the radio signal being organized in packets having each a header transmitted at a first channel in the hopping sequence comprising a detection sequence, and payload data encoding a message transmitted at following channels in the hopping sequence.

Abstract: The invention relates to a capsule (1) for preparing a beverage, comprising—a core material (3) having a pressed product and—a shell (2) enclosing the core material, the capsule (1) having in a breaking strength test a maximum percentage expansion of at least 15% in a direction transverse to a pressing direction.

Abstract: Microtechnologically prepared component as a flow cytometer. The component contains a preparation area to specifically influence and separate the particles, preferably by dielectrophoresis, a measuring channel area for characterizing the particles, and a sorting area for sorting the particles identified in the measuring channel area by dielectrophoresis. The sorting includes switching elements which permit active guidance of the particles into two or more subchannels corresponding to the criteria which have been registered in the measuring channel area. With a component configured in this way for the use of a flow cytometer, quick and precise sorting of particles, in particular biological cells in a suspension, can be implemented.
