Abstract: The present invention relates to an electronic fuse device. The electronic fuse device includes: a semiconductor switch, a load current detecting device, and a load current monitoring unit. The load current detecting device is configured to detect a load current flowing through the semiconductor switch and is configured to provide a corresponding load current signal. The load current monitoring unit, to which the load current signal is provided, is configured to evaluate the load current signal by means of an evaluation procedure. The load current monitoring unit is configured to execute the evaluation procedure only if at least one test parameter exceeds an associated threshold value.

Abstract: The present invention relates to an electronic fuse device. The electronic fuse device includes: a semiconductor switch and a current monitoring unit. The current monitoring unit is configured to continuously detect a load current flowing through the semiconductor switch during operation and to determine a load current value indicating the load current. The current monitoring unit includes a filter unit for filtering a detection signal detected by the current monitoring unit, and the current monitoring unit includes a correction unit which is configured to determine a measure of dispersion of the load current value and to carry out a correction of the load current value based on the determined measure of dispersion.

Abstract: The present invention relates to a method for checking the switch-off capability of an electronic fuse which is arranged between a voltage source and a consumer. The method includes monitoring a voltage at the consumer, switching the electronic fuse to a non-conductive state, and checking whether the voltage at the consumer drops to a threshold voltage within a set time. The present invention also relates to a system for checking the switch-off capability of an electronic fuse. The system includes a voltage source, a consumer, an electronic fuse between the voltage source and the consumer, a voltage measuring device to measure the voltage at the consumer, and a checking unit. The checking unit monitors the voltage at the consumer via the voltage measuring device, switches the electronic fuse to a non-conductive state, and checks whether the voltage at the consumer drops to a threshold voltage within a set time.

Abstract: A method for monitoring a circuit, in particular in order to make possible a predictive maintenance. At least one parameter is measured at least at one measurement position. The at least at one measurement position is located on or in the circuit. The at least one parameter is acquired. At least one actual value is calculated based on the at least one parameter. A deviation of the at least one actual value is determined from a target value. An analysis of the deviation is performed. An analysis result is output based on the analysis.

Abstract: A device for separating sheet material has an actuator and a sheet material holder coupled thereto. The actuator is designed for moving the sheet material holder. The sheet material holder is designed for receiving an individual sheet material piece from a sheet material stack in which the sheet material pieces are arranged in a layered manner one above another along a vertical direction. The actuator is designed to set the sheet material holder into an oscillating rotational movement about a rotation axis that lies substantially parallel to the vertical direction, in order to receive the individual sheet material piece from the sheet material stack.

Abstract: A device and a method for separating sheet material is provided. The separation of sheet material is not effected statically, but a suitable pick-up position and/or a suitable pick-up mechanism is selected for each sheet material piece, for example in dependence on the quality of a surface of the sheet material piece to be picked up, in order to pick up the sheet material piece from the sheet material stack and remove it from the same.
