Using the apparatus and method, it is possible to ascertain, from parts of adherent cells to entire groups of adherent cells, the mechanical properties in the natural, adherent state of the cell(s) in spatially selective, temporally selective and contactless fashion.

Abstract: A method with a hydraulic pressure medium supply arrangement for an open hydraulic circuit having a hydraulic machine, an adjusting mechanism, and an electronic control unit is disclosed. The method includes the steps of reading an actual value and a setpoint value associated therewith for hydraulic operating variables of the hydraulic machine into a first external control loop and determining the first manipulated variables resulting therefrom. In further steps of the method, the actual values and further setpoint values of the hydraulic operating variables are read into a second external control loop, compared with one another, and, on the basis thereof, at least one second manipulated variable is determined. Depending on the first and second manipulated variables, a setpoint adjustment speed is then determined as a manipulated variable for the adjusting mechanism. A hydraulic pressure medium supply arrangement which is designed to carry out the above method is also disclosed.
