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: A system comprising a capsule (1) and a capsule receptacle (31) of a preparation machine (30), wherein a sealing lip (10) corresponds with a groove (33) of the capsule receptacle (31) in such a way that the sealing lip (10) is received in the groove (33) and enables a tight connection with a contact surface (32) of the capsule receptacle (31).

Abstract: A filter with three phases comprising for each phase an input terminal, an output terminal and a capacitor, wherein for each of the three phases the input terminal is electrically connected via a connection point to the output terminal, wherein the connection points of the three phases are electrically connected via the three capacitors in star and/or delta form, wherein the filter comprises a housing containing two coil blocks, wherein the housing comprises a first side and a second side opposite the first side, wherein the two coil blocks are arranged along a line between the first side and the second side, wherein a fan for cooling the two coil blocks is arranged on the first side of the housing, wherein the larger of the two coil blocks is arranged between the fan and the smaller of the two coil blocks.

Abstract: A method and a device for monitoring a monitoring region with at least two image sensors. A sub-region of the monitoring region is monitored by each of the image sensors, wherein each image sensor detects objects to be monitored that are located within the sub-region monitored by said image sensor, and each image sensor outputs data relating to the detected objects and are disposed and oriented in such a way that the monitored sub-regions overlap and that each object to be monitored that is located in the monitoring region is always detected by at least one image sensor.

Abstract: Method for determining the length of a queue of objects in a predefined region having at least one entrance and at least one exit, in the course of which errors in the acquisition of objects entering or exiting the region are corrected during the determination of the length of the queue. In a first step, a specific entry signature E of each object entering the predefined region through the at least one entrance is determined with the aid of at least one first image sensor. Thereafter, the specific entry signature E is stored in an entry list of a calculation unit, each entry signature E being provided with an index value i reflecting the temporal sequence of the entries. In addition, a value L reflecting the length of the queue of the objects is increased by one.

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.
