| A UML state may be divided into regions. Each region contains sub-states. Regions are executed in parallel. You can think of regions as independent state machines displayed in one diagram. The state machine below (Fig. 1) shows several regions each running in parallel in the state '' | A UML state may be divided into regions. Each region contains sub-states.

| Consider a microwave oven. The power setting, light and microwave radiator are be considered as independent (concurrent) parts of the oven, each with its own states. The door and timer as the main external trigger are used in the regions to trigger state transitions. For example the radiator is switched on if the door gets closed and the timer is > zero. | Consider a microwave oven.
