Abstract: The invention relates to a method for communication between a third-party component (4) on a user device (2) and a service component (10) in the cloud (3), wherein: the service component (10) is signed by a data ID (13); the third-party component (4) provides component data (20); the component data (20) are marked by the data ID (13) in order to generate marked component data (21); the marked component data (21) are transferred to the cloud (3); and the marked component data (21) are assigned to the service component (10) having the data ID (13).

Abstract: It is known that a multiplicity of devices receive data from the cloud and make specific changes of state on the basis of these data. An example that can be mentioned is switching on a lamp or changing a color of a light source.

Abstract: The invention relates to a method for certifying an application-specific cryptographic key in a certificate exchange service (30), comprising: receiving (130) a cryptographic attestation certificate (22) for an application-specific public key from an application (20) in an apparatus (10); checking (34; 136) the validity of the attestation certificate (22); and, if the attestation certificate (22) has been recognized as valid, comparing (34; 138) at least some information that has been extracted from the attestation certificate (22) with predefined reference information, and if the comparison reveals that a new certificate should be created, forming (36; 140) a new application-specific certificate (24) that comprises at least the application-specific public key extracted from the attestation certificate (22) and at least some of the information from the attestation certificate; transmitting (150) the new application-specific certificate (24) to the application (20), and to a method for requesting such certific

Abstract: The invention relates to a method for identifying an application (12) that is executed in an apparatus (10) to another communication participant, comprising: obtaining (200) a connection request for a secure connection between the application (12) and the other communication participant (30); forming (202) an information element (60) that comprises at least one item of information about the application (12); signing (204) the information element with a first secret key (52), which is part of a cryptographic asymmetric key pair that is certified by an information certificate (50) issued by an external trusted authority; incorporating the signed information element (60) into a connection request message (70), signing the connection request message with a secret device-specific key that is part of a cryptographic asymmetric key pair that is certified by a device-specific certificate of the apparatus, and transmitting the connection request message to the other communication participant.

Abstract: An evaluation device for evaluating an input signal (7), wherein the evaluation device has a base network (11), wherein the base network (11) is produced by a machine learning system and has an input layer (2) and a boundary layer (13), wherein the input layer (2) and the boundary layer (13) have a plurality of layers (4) arranged between them that are connected by means of connections (6), wherein the base network (11) is trained for a basic purpose, having at least two special networks (12, 12a-12b), wherein the special networks (12, 12a-12b) each form a machine learning system and each have a special network input layer (14a, 14b) and a special network output layer (15a, 15b), wherein the special networks (12, 12a-12b) are each trained and/or trainable for a special purpose.

Abstract: The present invention relates to a communications system (1) with at least one node (101, 102, 110), a control instance (10) and a shared communications medium (11). The at least one node is designed to receive messages that are or were transmitted in a first transmission mode. This first transmission mode has a lower data transmission rate and/or transmission complexity than a second transmission mode. The control instance (10) determines a first of the nodes in order to transmit data thereto in the second transmission mode or in order to release the shared communications medium (11) for the first node to transmit data in the second transmission mode. The control instance communicates this to the first node by means of a message (501, 502, 503, 504). This message is transmitted in the first transmission mode.

Abstract: The invention relates to a method for operating a processing device (2) that comprises a control unit (4) and at least one field device (8, 10, 12) connected to said control unit (4) for the purpose of exchanging data via a data exchange connection (6), in which a field device (10) to be exchanged is replaced by another field device (12) to be inserted, and which comprises the steps of: generating an exchange signal (AS) using an exchange signal generator (14), and transmitting said exchange signal (AS) to the control unit (4). The invention also relates to a corresponding processing device and a control unit, field device, and exchange signal generator, as well as a computer program.

Abstract: A constant torque propeller mechanism allows a propeller to operate very efficiently in both takeoff and cruise flight conditions, which significantly improves aircraft performance. The constant torque propeller mechanism introduces a lightweight and passive propeller control system which requires no electrical power to operate, but at the same time improves the efficiency of the motor propeller combination over the flight envelope.
