Abstract: The invention relates to a method for producing a cryptographically signed transaction for the transfer of an amount of a currency within a blockchain. The transaction comprises one or more inputs and one or more outputs. The method comprises: retrieving the one or more inputs, the inputs being a reference to one or more previous transactions, determining the one or more outputs, each output defining an amount to be transferred to a receiver indicated in the respective output, adding security information, the security information defining directly or indirectly a maximum amount to be spent with the transaction, and cryptographically signing the transaction by adding signature information.

Abstract: A release apparatus for releasing a satellite comprises a release plunger that can be preloaded by a release spring and that is held in a preloaded position by two two-armed pivot levers pivotable about a respective pivot axis, wherein each pivot lever can be held against a force of a spring in a holding position by a release element.

Abstract: A method for controlling and managing a wireless connection for data communication between a mobile device and a broadband radio network is suggested, in the context of which method, the log in and the authentication of the mobile device at the base stations of the broadband radio network takes place via a narrow band radio network with lower data rate and larger range than the broadband radio network.
