A method for driving at least one mover is specified, wherein the mover comprises at least a second magnetic field generator, wherein the mover is movable on a drive surface comprising a plurality of sectors, wherein the sectors comprise magnetic field generators for generating at least one magnetic field, wherein path planning is carried out for the mover from a starting point to a target point on the drive surface, wherein at least one graph with nodes and edges is used for the path planning, wherein a path for the mover is determined on the basis of the graph.

Device and method for path planning for a mover of a drive device

A device and a method for determining a travel path for at least one mover on a drive surface, the mover comprising at least one second magnetic field generator, the device comprising a plurality of plate-shaped sectors, where the sectors comprise magnetic field generators for generating magnetic fields, and where the sectors form the drive surface. At least one virtual path network is provided on the drive surface, where a travel path for a mover is determined on the path network.

Device for driving at least one mover over a drive area

A device and method for preventing a collision when determining travel paths for at least two movers on a drive surface, each mover comprising at least a second magnetic field generator, the device comprising a plurality of sectors, the sectors comprising magnetic field generators for generating magnetic fields, the sectors forming the drive surface. A path planning for at least two movers is carried out, at least the two movers being assigned a priority, the priorities of the movers being taken into account in the path planning such that a path of a mover is assigned a priority in the path planning of the travel paths of the movers, and a travel path of a mover with a higher priority takes precedence over a travel path of a mover with a lower priority, so that a collision of the movers is prevented.

Device and method for preventing a collision when driving at least two moving elements on a driving surface

A method for driving at least one rotor in a planar drive system. The rotor has a device for generating a magnetic field. The rotor can be moved on a drive surface formed by stator modules comprising a magnetic field generator. A virtual two-dimensional potential curve is determined for the rotor, with a target point having an attractive potential. A virtual force vector is determined with a vector direction and a vector length at a first position of the rotor, which is determined from the virtual two-dimensional potential curve. A magnetic drive field interacting with the magnetic field of the rotor is generated by the magnetic field generator such that a resulting force is applied to the rotor by interaction of the magnetic drive field with the magnetic field. The direction of the resulting force is based on the vector direction, and the strength is based on the vector length.

Method for driving a rotor of a planar drive system

A method for preventing collisions when driving at least two movers on a drive surface, each mover comprising at least one magnetic field generator, with a device comprising a plurality of plate-shaped sectors, the sectors each comprising at least one electric magnetic field generator. The sectors form the drive surface, generating magnetic fields via control of a power supply of the electric magnetic field generators such that the movers are movable over the drive surface in at least one direction. A first path planning for the first mover is carried out, an estimated second travel path of the second mover is determined or received, and the estimated second travel path of the second mover is taken into account in the first path planning of the first mover to determine a first travel path for the first mover such that collision of the first mover with the second mover is prevented.

An apparatus for treating a medical fluid is provided which includes a treatment machine having a coupling surface, with a cassette made of a hard part having liquid-conducting passages which are covered by a flexible film being able to be coupled to the coupling surface of the treatment machine. A corresponding medical cassette is also provided. An air-free coupling of the flexible film of the cassette to the treatment machine is ensured in that air can be sucked out areally along a plane between the flexible film and the coupling surface during the coupling process and/or with a coupled cassette. A method for coupling the cassette and a method for checking the leaktightness of the cassette via the vacuum control of the air suction is also provided.

Device and method for treating a medical fluid and medical cassette

Certain aspects of the invention relate to a connector including at least one first connector part and at least one second connector part. The connector parts can be connected to one another in a fluid-tight manner and can be locked to one another via at least one closure element. One of the connector parts has at least one sealing element (e.g., a septum or a sealing disk) that blocks a throughflow in the closed state and which can be opened, and the other one of the connector parts has at least one opening element for opening the sealing element. One of the connector parts has at least one projection and the other one of the connector parts has at least one receiver, and the opening element and the sealing element are arranged with respect to one another such that the opening element only opens the sealing element when the projection has been introduced into the receiver.
