Abstract: The present invention relates to a method to protect, in a secured container using an encryption key, a set of mixed sensitive and public data to be transferred to an entity. The method includes the steps of: generating a random key, ciphering the set of mixed sensitive and public data using said random key to obtain a ciphered set of data, generating an initialization value, and defining configuration information for the secured container. The initialization value, the configuration information and random key form a preamble. The preamble and the ciphered set of data are encrypted. The initialization value renders the resulting encrypted data variable from a secured container to another even in case of repetitive configuration information in the preamble.

Abstract: A magnetically levitated rotor includes a magnetically effective core and a sheathing made of a thermoplastically processible fluoropolymer. The sheathing completely encloses the magnetically effective core. The magnetically effective core comprises at least one permanent magnet and each permanent magnet has a metallic coating for protection against acidic or chemically aggressive substances. A plastic coating is disposed between the metallic coating and the sheathing, and includes a polymer belonging to the family of parylenes.

Abstract: A flow rate of a fluid in a flow system is determined based on one or more parameters of the flow system, the parameters not including the flow rate itself. The flow rate is also measured with a calibration sensor, and the measured flow rate is used to calibrate how the flow rate is determined.

Abstract: The invention relates to a method for the calibration of a flow measurement in a flow system (1), wherein a fluid (2) is conveyed through a flow connection (3) of the flow system (1), and a flow rate of the fluid (2) is determined through the flow measurement from a working parameter of the flow system (1). In accordance with the invention the flow rate of the fluid (2) is determined at a pre-determined point in time with a calibration sensor (4) in a calibration measurement and the flow measurement is calibrated anew with the help of the calibration measurement. Furthermore, the invention relates to a flow system to carry out the method in accordance with the invention.

Abstract: An electrical rotary drive, designed as a bearingless motor, has a magnetically journalled rotor (3) and a stator (2) which comprises a drive winding (6) having at least two loops (61, 62) for producing a magnetic drive field which produces a torque on the rotor (3), and has a control winding (7) having at least three loops (71, 72, 73, 74) for producing a magnetic control field by means of which the position of the rotor (3) with respect to the stator (2) can be regulated, with each loop (61, 62) of the drive winding (6) belonging to a different electrical drive phase and each loop (71-74) of the control winding (7) belonging to a different electrical control phase, and having a setting device (4) which supplies each loop (61, 62) of the drive winding (6) and each loop (71-74) of the control winding (7) with a phase current or a phase voltage as a setting parameter, with the setting device (4) being designed in such a manner that the setting parameter for each loop (61, 62) of the drive winding (6) and for e

Abstract: The arrangement or apparatus for operating a magnetically suspended, electromotoric drive apparatus in the event of a mains disturbance comprises a drive converter feeding the drive apparatus, a driver feeding a magnetic bearing and a voltage converter, which are connected to a common intermediate circuit. The voltage converter feeds a stopping control apparatus and the drive converter can be switched to a regeneratively acting mode of operation by the stopping control apparatus in the event of a mains disturbance in order to provide at least the driver feeding the magnetic bearing and the stopping control apparatus with electrical energy via the intermediate circuit.
