Abstract: Various embodiments of the teachings herein include a computer-aided method for transforming data in a relational database, containing sensor measurements, into RDF data blocks of a graph database. The method may include: providing a R2RML mapping file; breaking down and converting the data using the mapping file and a first mapping parser; generating a generation of RDF data blocks; and storing the generation as a database. After the data have been broken down and converted, checking a quality of the obtained R2RML mapping and creating a second R2RML mapping file, on the basis of which the relational data are broken down and converted into RDF data blocks. The second R2RML mapping, during the preparation of the relational data into RDF data blocks, automatically stops the processing of relational data that are not to be resolved and thus optimizes the energy efficiency of the preparation.

Abstract: Various embodiments include a driver circuit for controlling a semiconductor switch. Some circuits include: a contact for connection to a control terminal of the semiconductor switch; and a device to carry out a measurement of a value dependent on the level of the current flowing through the semiconductor switch, in the course of a switch-off process of the semiconductor switch.

Depending on the size of the value, the device activates a control measure to reduce the change over time in the current flowing through the semiconductor switch.
