Abstract: A medical device substrate with a coating including a functional layer located on the substrate, with the functional layer including at least one sugar alcohol and being bonded to the substrate directly or indirectly via a functionalization of the sugar alcohol. Alternatively, the functional layer may also include other saccharides, in which case it is essential that polymerization of the saccharides takes place only upon bonding to the substrate. The inventive medical device exhibits reduced platelet adhesion and aggregation.

Abstract: A method for controlling an energy grid. In this method, first pieces of information about the past behavior of at least one user at the energy grid are ascertained by a processing unit assigned to the user, homomorphically encrypted and transferred homomorphically encrypted to a first data memory. An external processing unit reads the homomorphically encrypted first pieces of information, calculates as a function thereof second, homomorphically encrypted pieces of information about a predicted, future behavior of the user and stores the second, homomorphically encrypted pieces of information on a second data memory. The second, homomorphically encrypted pieces of information are read out from the second data memory and decrypted by the processing unit assigned to the user. A control of the energy grid takes place as a function of the decrypted second pieces of information.

Abstract: A method for the reliable provision of measurement data of at least one sensor of a smart meter in a decentralized transaction database. The method includes forming a measurement data set, which comprises measurement data recorded by the at least one sensor at least at one point in time, the meter digitally signing the measurement data set using a secret key; the meter transmitting the digitally signed measurement data set to a first protocol, which is implemented as a computer protocol executed in automated fashion on the transaction database, the verification protocol verifying the digitally signed measurement data set using a public key, which corresponds to the secret key; and, if the measurement data set is successfully verified, providing the measurement data set to at least one second protocol, which is implemented as a computer protocol executed in automated fashion on the transaction database.

Abstract: A computer-implemented method for controlling a utilization of a power plant capacity of a power plant. The power plant capacity is divided into multiple portions. A particular portion of the power plant capacity is represented by a token. Use of the portion of the power plant capacity is determined by assignment of the token to a token wallet.
