Abstract: A sensor device for a monitoring of a coupling state of a coupling element, in particular a coupling bolt, preferably a kingpin, of a trailer, in particular a semitrailer, with a corresponding coupling element of a towing vehicle, in particular a semitrailer tractor, with at least one sensor which is at least configured for a recognition, in particular a detection, of a relative position of the coupling elements with respect to each other, wherein the sensor is realized as an ultra-wideband sensor.

Abstract: A data provision method includes a data provision step in which electronic data are generated by at least one data generation device, and includes a provision step in which the electronic data are provided in the form of data packages via a data transmission network, wherein in the provision step the data packages are first of all, preferably directly, written into a blockchain or into a distributed ledger, and wherein in the provision step the data packages are provided, preferably directly, from the blockchain or from the distributed ledger via the data transmission network, wherein provided data packages include at least one encrypted and/or digitally signed data field with a reference to an, in particular random or quasi-random, subsequent address of the next data package following the data package.

Abstract: A traffic management device, in particular a stationary traffic management device, preferably for managing at least partially and/or at least time-segment-wise self-driving vehicles, includes at least one sensor module having at least one sensor that is configured for sensing at least one item of information and/or at least one parameter of at least one object moving in a field of view of the sensor, the sensor is embodied as an ultra-wideband sensor.

Abstract: A method for an assignment of at least one creator to a digital media file comprises at least one method step in which the digital media file is recorded by means of a recording device of a recording apparatus, in particular a front-facing camera of the recording apparatus, and is provided with metadata, wherein the metadata comprises at least one creator information, the creator information being generated automatically in the recording period of the digital media file, wherein the creator information is realized as a user identifier, and wherein in the method step at least the user identifier is determined and/or verified by a safety device, wherein the safety device comprises a camera of the recording apparatus, in particular a rear-facing camera of the recording apparatus, by means of which the determination and/or verification of the user identifier of the user making the recording is carried out by the recording device in the recording period of the digital media file.
