Abstract: In a method for operating a control device for controlling an electric motor, in particular a steering system, in which the control device includes at least one power supply, at least one power element which is operatively connected to the power supply, at least one reverse polarity protection switch arranged in a power current path between the power supply and the power element, and at least one logic unit, at least one first voltage value correlated with an intermediate circuit voltage and at least one second voltage value correlated with a supply voltage of the logic unit are determined and linked to one another and evaluated to determine a faulty actuation of the reverse polarity protection switch.

Abstract: A control device for operating an electric motor, in particular a steering system, includes a power electronics, a primary driver unit provided for actuating the power electronics in a normal operating state, and a secondary driver unit connected in parallel to the primary driver unit and provided for actuating the power electronics in at least one fault operating state in which a malfunction and/or failure of the primary driver unit occurs. The secondary driver unit comprises a power source having an adjustable current strength for controlling a switching state of at least one circuit breaker of the power electronics. An absolute value of the power source in the normal operating state is set to a first value which is below a first limit value, and in the at least one fault operating state it is set to a second value which is above a second limit value.

Abstract: A method and apparatus are provided for obtaining a sub-resolution spatial information of a sample labeled with at least one type fluorescent label. The sub-resolution spatial information has localization information about the positions of fluorescent molecules of the at least one type fluorescent label in at least one spatial direction. The method acquires localization image data by employing fluorescence localization microscopy. The acquired localization image data is processed to obtain the localization information about the positions of fluorescent molecules of the at least one type fluorescent label in at least one spatial direction. The step of processing includes determining in each of the detected images of the series the positions of the barycenters of the detected fluorescence emission distributions from the single fluorescent molecules of the one or more fluorescent labels in at least one spatial direction.
