Abstract
An apparatus and system for automatically opening and closing a bathroom stall door. The system includes a motor for driving the door open or closed. A control unit controls the operation of the motor. An outer activation sensor senses a presence of a person in proximity to the outer activation sensor. Upon sensing a presence of a person in proximity to the outer activation sensor by the outer activation sensor, the control unit commands the motor to open the door and automatically close the door after a predetermined time period. When an inner activation sensor senses a presence in the proximity to the inner activation sensor, the control unit locks the door lock. When the inner activation sensor senses a presence in proximity to the inner activation sensor a second time, the control unit unlocks the door lock and commands the motor to open the door.
