Abstract: A device for transforming a dataset with a secret key, wherein a query unit (1) is connected via a bidirectional communication interface (2) to a transformation unit (3), has a memory (4) for the secret key and a processor (5) for transforming the dataset. For reliable and secure execution of digital transactions, the query unit (1) has optical transmitters transmitting in parallel codewords of the dataset translated into two-dimensional codewords to optical receivers of the transformation unit (3), and the transformation unit (3) has optical transmitters transmitting in parallel codewords of the transformed dataset translated into two-dimensional codewords to a plurality of optical receivers of the query unit (1). The transmitters and receivers of a unit are arranged each in a two-dimensional grid and opposite and at a distance from the receivers and transmitters of the other unit.

Abstract: A method and a first device for providing variables for obtaining a service at a service location, the service location including an access lane, and at least one sensor device assigned to the access lane being provided, including a step for detecting data values with the aid of the sensor device, the data values representing variables for obtaining the service as a function of at least one part of the access lane, and including a step for providing the variables represented by the data values in such a way that the variables are made accessible to a first vehicle, which is not in the at least one part of the access lane.

Abstract: A method for ascertaining data for an autonomous driving operation of a motor vehicle within a parking facility using one or multiple surroundings sensor system(s). The method includes detecting present surroundings of the motor vehicle during a manually guided trip of the motor vehicle within the parking facility with the aid of the surroundings sensor system(s) to ascertain the surroundings data corresponding to the surroundings, and ascertaining the data for an autonomous driving operation of the motor vehicle within the parking facility based on the surroundings data so that the motor vehicle may autonomously drive within the parking facility based on the ascertained data.

Abstract: A method, of a system of a parking facility, for warning at least one road user located within the parking facility includes: monitoring the parking facility using a monitoring system of the parking facility, ascertaining, based on the monitoring, whether the road user is to be warned of a hazard present within the parking facility, and warning the road user if the ascertainment has indicated that the road user is to be warned of a hazard.

Abstract: A method for the driverless driving of a motor vehicle parked at a start position of a parking facility from the start position to a destination position of the parking facility. The method includes checking whether one or several of the following minimum conditions are fulfilled: an order for the driverless driving exists, the driver of the parked motor vehicle handed over the responsibility for the parked motor vehicle, and a minimum distance of one or multiple persons from the parked motor vehicle is maintained, and beginning with the driverless driving of the motor vehicle only if one or several of the minimum conditions are fulfilled. A corresponding device and a computer program are also described.

Abstract: A parking lot is set up for the parking of motor vehicles. A method for managing the parking lot includes steps of determining a maximum number of motor vehicles able to be parked in the parking lot, of counting of arriving and departing motor vehicles, of determining a number of motor vehicles parked in the parking lot on the basis of the counted motor vehicles, and of determining a number of motor vehicles that are additionally able to be parked in the parking lot.
