Networked Devices Meeting Dependability while Supporting the Medical Supervision of Cardiac Patients under Rehabilitation

Networked customer devices provide a powerful, flexible and cost-efficient implementation environment for cyber-physical system applications but due to their inherent unreliability can directly support limited dependability only. Since in such an environment non-critical functions can collect, process and prepare comprising data which supports the adaptation and optimization so that new and significantly enriched medical functions can be realized, we envisage Big Dependable Systems (BDS), a corresponding upcoming class of systems. Major steps towards their systematic development utilize approaches for communication and dynamic configuration in service-oriented systems, for automated monitoring and repair, and for in-built fault tolerance. We report on respective approaches examined and on a set of pilot applications before the vision of BDS is outlined before that background. The pilot applications employ cyber-physical systems in order to support rehabilitation training sessions which are remotely supervised and take place as well at home as in a virtual reality.
