Abstract.
REFLEX (Real-Time Event Flow Executive) is a generic event driven OS for 
embedded devices. Event handlers and control functions are all represented by 
passive objects that are scheduled preemptively according to an earliest 
deadline first (EDF) strategy. All sensors, control functions and actuators of a 
typical embedded control system are represented by objects that can communicate 
with each other by means of events. In this talk we present the design and 
implementation of a complex house control system that has been implemented on 
top of REFLEX.
