    • A method for determining a patient-specific contrast medium impulse response function includes providing patient-specific test bolus contrast medium behavior data and a number of basic impulse response functions on the basis of a defined test bolus input function. Simulated test bolus contrast medium behavior functions are generated by combining the basic impulse response functions with the test bolus input function. The simulated functions and the patient-specific data are fitted to one another by varying a number of fitting parameters to obtain optimum fitting parameter values, and the patient-specific contrast medium impulse response function is then created based on the basic impulse response functions and the optimum fitting parameter values. A method for predicting a likely contrast medium behavior and a method for controlling a medical imaging system are also described. Additionally a corresponding apparatus, a control device and an imaging system having such a control device are also described.

    • A hermetically sealed optical fiber lens arrangement, particularly for optoelectronic modules, includes an optical fiber which extends through a metal tubule and is fastened therein. The metal tubule is attached through a flange at an aperture in a wall of a module housing, and includes a spherical lens fastened in the module housing. The metal tubule supporting the optical fiber is adjusted in the flange by axially displacing it a preset focal distance from the spherical lens, and is fastened in the flange. The spherical lens mounting takes the form of a metal tubule and is adjusted at the frontal side of the flange adjacent to the housing by transverse displacement and fastened, so as to achieve optimum alignment of the optical axes of said arrangement, and the flange is hermetically sealed directly or through an annular projection of the spherical lens mounting to the modular housing wall.

    • A drive system has a drive motor with an associated current regulator. The current regulator controls the semiconductor contact elements of an electronic power stage, which is arranged downstream from the drive motor. This control is a function of a rotor-position sensor, whose rotor part is coupled to the rotor of this motor and has a number of magnetic poles corresponding to the number of poles of the drive motor. Furthermore, the current setpoint that is supplied to the current regulator is increased by overlapping an auxiliary voltage during the respective instant of commutation. Torque fluctuations which are caused by manufacturing tolerances can be then be eliminated. On the circumference of the rotor part, a number of magnetic field sensors corresponding to the number of phases m of the drive motor are mounted at a spatial distance of 360.degree. /(p.m) to each other where p is the number of pole pairs of the drive motor. The auxiliary voltage is derived from the analog voltage signal of the magnetic field sensors.

    • During the production of a product by means of a production machine, an evaluation device receives actual states of components of the production machine, detected by sensors at detection times, and/or operating states of a control device of the production machine at the defined detection times. The evaluation device compares the states of each detection time transmitted thereto with pre-defined state combinations and thus determines fulfilled state combinations. For each fulfilled state combination, the evaluation device selects relevant states from the states of the respective detection time transmitted thereto, and corresponding information and the respective detection time are stored with the relevant states such that they are available for other evaluations.
