Abstract: A device for pneumatically driving a rotor in a balancing machine has at least one drive nozzle, which is connectable to a compressed-air line and which serves for generating a driving air stream which can be directed onto the rotor, and at least one braking nozzle, which is connectable to a compressed-air line and which serves for generating a braking air flow. The braking air flow can be directed onto the rotor in a direction opposite to the direction of rotation of the rotor. Also a base plate is arrangeable with a spacing to the rotor and on the base plate, the nozzles are movably arranged, such that the spacing between nozzles and rotor is adjustable.

Abstract: A method and device are disclosed for determining critical information interfaces between fields of activity of an electronically documented process, the method including: (a) providing a binary dependency matrix between the fields of activity of the process; (b) rating the information interfaces between the fields of activity of the process that are specified in the binary dependency matrix based on predefined criteria that are read out from a criteria database in terms of their respective expression in relation to the read-out criteria in order to generate a numeric dependency matrix; and (c) evaluating the generated numeric dependency matrix in order to determine information interfaces of the process that are critical in respect of at least one target function.
