The present disclosure relates to the field of processing data in the stream processing network, such as processing data having data streams associated with multiple owners or entities. A method is disclosed of secure processing of input data by a stream processing network having first and second processing units, wherein the method can include: a) receiving input data from a communication channel, wherein the input data includes a first data stream associated with a first owner and a second data stream associated with a second owner; b) distinguishing data packets of the first data stream from that of the second data stream; and c) processing the first data stream with the first processing unit.

Method for processing data streams with multiple tenants

A method for planning a charging of an electrical vehicle comprises receiving a request for charging from an electrical vehicle at a charging pole, determining a charging time slot for the electrical vehicle based on the request for charging, scheduling the charging time slot for the electrical vehicle, predicting a load requirement for the charging pole based on the request for charging and the charging time slot, and sending the load requirement to a grid operator supplying the charging pole with electrical power.

Self-managing charging poles

A method of inspecting equipment of a power system can involve identifying a geographical area including a presumed faulty piece of equipment with a central computer system of the power system; determining a contact (e.g., a person) at the geographical area; sending a request for inspecting local equipment in the geographical area to the person; taking a picture, by the person, of a piece of local equipment; transmitting the picture to the central computer system; and evaluating at the central computer system, whether the piece of local equipment in the picture is faulty or not.

The client requests from the authentication and authorization server a capability for accessing the target server. The authentication and authorization server sends client a capability (cap) comprising the public key (pub) of the client, said capability being signed with a private key (priv) of the authentication and authorization server. The client sends the capability (cap) to the target server. If the capability is valid, the target server grants the client access and a data exchange session can be initiated. The disclosed protocol is scalable, as it does not require individual configuration of each target server device, allows revocation of user access within reasonable time, stores no compromisable secret data on any target server device, enables individual access permission per user, and accountability of each user.

Access control protocol for embedded devices

The present invention is concerned with an alarm system and a method for suppressing redundant alarms in a monitored system. The alarm system comprises a process control unit, an FDI unit, a filter, and an alarm display unit. The process control unit detects anomalies in the monitored system and generates alarms corresponding to them. The FDI unit diagnoses failures in the monitored system and generates a failure-cause-effect graph comprising a list of generated alarms, along with the alarms corresponding to the causes and effects of each listed alarm. The FDI unit dynamically updates the failure-cause-effect graph concurrently with the generation of alarms by the process control unit and the diagnosis of failures by the FDI unit. The filter receives the generated alarms and identifies redundant and not-yet-classified alarms from the received alarms, by using the failure-cause-effect graph. The filter suppresses the identified redundant alarms and passes on non-redundant and the not-yet-classified alarms to the alarm display unit, for display.
