This paper describes an heterogeneous model of a power window which is available on the ReMoDD repository. This model uses timed finite state machines for modeling the controller of the power window, synchronous data flows for modeling the mechanical part of the window, and discrete events for modeling the communications between the components on the car's bus. An important aspect of this model is the specification of the semantic adaptation between the heterogeneous parts of the model. This semantic adaptation is made for data, control, and time. The semantic adaptation of control and time relies on the TESL library which is an implementation of the model of time used in the ModHel'X platform. The model can be run using a simulation scenario with a graphical display of the outputs. The semantic adaptation can be disabled in order to show how it affects the behavior of the model. The demo can also be run with a graphical interface and a user in the loop.
