Title: Sten Edvard Johnsson: Innovator in Software Update Technologies

Introduction

Sten Edvard Johnsson is a notable inventor based in Farsta, Sweden. He has made significant contributions to the field of software updates, holding a total of 5 patents. His innovative approaches aim to enhance the efficiency and reliability of software processing systems.

Latest Patents

One of his latest patents is a state copying method for software updates. This method provides a scalable approach to updating software in a computation system with at least two logic partitions. The process allows for the state of new software in a standby partition to be updated to match the state of old software in an executing partition while maintaining the execution of the old software. Data is transferred from the executing partition to the standby partition in a scalable manner. Once the states of both partitions are aligned, the execution switches to the new software, minimizing disturbance during the update.

Another significant patent is the apparatus and method for message conversion. This invention aims to facilitate a highly efficient upgrade of software in computer-based systems. The message conversion apparatus includes an interface unit for message conversion information (MCI), which describes messages exchanged in a software processing system before and after an upgrade. The message conversion means allows for the conversion of messages between old and new representations, ensuring compliance with the specifications outlined in the MCI. This innovation enables a disturbance-free upgrade of software with minimized system downtime.
