Abstract: A method for problem diagnosis in a robot system having one or more robots includes the steps of: a) receiving (S1) a first problem message from a robot of the robot system, the first problem message including one or more data elements descriptive of a problem experienced by the robot; b) receiving (S1) a subsequent problem message from a robot of the robot system; c) if a time elapsed between receipt of the subsequent problem message and receipt of an immediately preceding problem message is shorter than a predetermined threshold (S2), adding the subsequent problem message to a message set which comprises the immediately preceding problem message (S3); and d) if the time elapsed is longer than the predetermined threshold (S2), terminating (S4) the message set of the immediately preceding problem message without adding the subsequent problem message, and establishing (S5, S6) a new message set.

Abstract: Technologies for producing training data for identifying degradation of physical components include a system. The system includes circuitry configured to apply an accelerated degradation process to a physical component of an industrial plant. Additionally, the circuitry of the system is configured to obtain measurement data indicative of visual characteristics of the physical component at each of multiple phases of degradation, wherein the measurement data is usable to train a neural network to identify a phase of degradation of another physical component.

Abstract: A method for distributing keys for encrypted data transmission in a preferably wireless sensor network. Initially nodes store a subset of keys from a set of keys. A powerful sink node located in the centre of the wireless sensor triggers the key election procedure and sensor nodes choose from a locally broadcasted key-ID list one key to be stored on each node. All other initially stored keys are subsequently deleted. The process is iteratively until the edge of the network is achieved. Such key pre-distribution suits for the encryption of reverse multicast traffic to the sink node which is the pre-dominant traffic pattern in wireless sensor networks.
