Abstract:
Automatically operating a door system is controlled by an affirmative action of a patron. An occupancy status of an inside area is provided to the patron approaching the door from an outside area. The patron is directed to request the door be opened in response to an unoccupied status. A presence of the patron in the inside area is sensed and the door automatically closed, and optionally locked. One actuator is set to an in use status indicating use of the inside area by the patron. A door ready for opening status is provided to the patron. With an affirmative action with a second actuator by the patron desiring to open the door and exit the inside area, the door is unlocked and opened. Sensing an absence of the patron within the inside area, the door is automatically closed, and first actuator reset to the ready state.
