To improve their condition, we propose LUXAMET, a bright light therapy system. This system has the potential relieve patients from some of the symptoms caused by seasonal depression. The system was designed with a formal and model driven design methodology. This methodology enabled us to minimize systemic hazards, like blinding patients with an unhealthy dose of light. This was achieved by controlling race conditions and memory leaks, during design time. We proof that the system specification is deadlock as well as livelock free and there are no invariant violations. These proves, together with the similarity between specification model and implementation code, make us confident that the implemented system is a reliable tool which can help patients during seasonal depression.

“…In the specification refinement phase, formal methods, such as Communicating Sequential Processes (CSP) [194], B-method [195] and petri nets, can be used to establish beyond reasonable doubt specific safety and reliability aspects of the diagnosis support system [196].…”
