Abstract: An energy supply system has a switch, which in an on state connects first conductors of a first line to second conductors of a second line and in an off state disconnects the first conductors of the first line from the second conductors of the second line. A measurement apparatus determines a difference value characterizing the phase difference between a first AC voltage signal at one first conductor and a second AC voltage signal at one second conductor. A control apparatus outputs a command via a signal transmission apparatus depending on the phase difference value. The first command enables a vehicle connected to the charging station to change the phase position of a fed-in AC voltage signal in the feed-in mode to reduce the phase difference, and the control apparatus enables a first change of state of the switch from the off state to the on state.

Abstract: A method for generating a resultant test plan includes generating a data record by measuring a measurement object. The method includes assigning at least part of the measurement object to an object class based on the data record. The method includes determining a test plan assigned to the object class as an object-class-specific test plan.

The method includes creating an adapted assignment by adapting the assignment based on: (a) object properties of the measurement object currently measured or (b) the resultant test plan assigned to the measurement object. The determining the resultant test plan is performed based on the adapted assignment.

Abstract: A method for generating a test plan for testing a measurement object includes obtaining a data record representing the measurement object. The method includes setting a reference structure based on the data. The method includes assigning at least one reference structure-specific test feature to the reference structure. A test is carried out based on data for the data record representing the measurement object as to whether structures that are similar to or the same as the reference structure are present. The reference structure-specific test feature is assigned to each similar or same structure as the structure-specific test feature. The method includes generating the test plan to include the structure-specific test features.

Abstract: A method and an apparatus for monitoring a motorcycle. Based on the acceleration-relevant data, a vehicle motion and a vehicle position in three-dimensional space are estimated. The vehicle position in space is analyzed and is evaluated as a normal or a critical riding state. A detection direction of a sensor unit is predefined in such a way that in an upright normal resting position of the motorcycle the detection direction lies in a horizontal plane, and the detected acceleration-relevant data encompass a first acceleration component in a longitudinal vehicle direction and a second acceleration component in a transverse vehicle direction. A riding state evaluated as critical is plausibilized with the estimated vehicle motion in order to recognize a critical resting position after an accident. An emergency call is generated when a critical resting position after an accident is recognized.

Abstract: An energy supply system has a switch, which in an on state connects first conductors of a first line to second conductors of a second line and in an off state disconnects the first conductors of the first line from the second conductors of the second line.
