    Abstract: An apparatus comprises a base plate configured to be coupled to a door, the door configured to be positioned in an open position and a closed position; a closing mechanism coupled to the base plate and configured to be coupled to a hinge of the door and having an unprimed state and a primed state, the closing mechanism configured to be transitioned between the unprimed state and the primed state by a user; wherein in the unprimed state the closing mechanism is decoupled from operation of the door; and in the primed state the closing mechanism is configured to move the door into the closed position responsive to receipt of a signal, and the closing mechanism is configured to allow movement of the door between the open position and the closed position in absence of the signal.

    Abstract: A barrier operator includes a motor, a controller operably connected to the motor, a sensor, and a control module. The motor is couplable to a drive mechanism of a barrier and is configured to move the barrier between open and closed positions. The sensor is configured to monitor an operating parameter of the barrier operator associated with movement of the barrier. The control module includes user input controls. The controller is configured to receive a first user input from the control module; initiate, in response to receipt of the first user input, operation of the motor for a first movement of the barrier to establish a first travel limit of the barrier; receive a first signal indicative of the operating parameter from the sensor; and generate, during the first movement of the barrier, a first force limit based on the first signal from the sensor.

    Abstract: An automatic opening and closing device of door includes a locking unit arranged on the door, a door driving unit configured for driving the door to open or close, a signal receiving unit configured for receiving external or internal signals of the door, and a control unit electrically communicated and connected with the signal receiving unit. The locking unit includes a lock and a power motor. The power motor and the door driving unit are electrically communicated and connected with the control unit. When the signal receiving unit senses a correct door opening signal from the inside or outside of the door, the control unit will first command the power motor to drive the lock to be unlocked and command the door driving unit to act to open the door. After a person has passed the door, the control unit will command the door driving unit to act to close the door and command the power motor to link and drive the lock to be locked. It can be noted that the person does not need to contact any part of the door or the lock, so as to prevent virus infection, which achieves an epidemic prevention effect.
