Latest Patents

Johansson's latest patents include "Methods and means for failure handling in process control systems." This patent describes a method for managing failures in a process control system that consists of multiple compute nodes. The system features at least two instances of virtualized distributed control nodes (VDCNs), where one serves as the primary VDCN controlling an automated process, while the other acts as a backup. The method involves detecting when the number of VDCN instances falls below a predetermined threshold and reassigning the primary role to the backup VDCN.

Another significant patent is the "Method for failure detection and role selection in a network of redundant processes." This invention outlines a process for detecting failures and selecting roles within a network of redundant processes. It includes a primary process that transmits a heartbeat signal at regular intervals to monitor the health of the network processes.
