A swing door operator system is described, the system including a first swing door operator, a second swing door operator, and at least one door leaf hinged connected at an opening in the wall. The first swing door operator is connected to a first side of the door leaf, the second swing door operator is connected to a second side of the door leaf, the first side of the door leaf is opposite to the second side of the door leaf, and the first swing door operator and the second swing door operator interact to move the door leaf between an open and closed position.

A powered actuation mechanism for operating a closure panel device coupled to a closure panel of a vehicle, the closure panel operated between a closed position and a partially open position, the mechanism including: a motor operatively coupled to a control member; a lever body mounted at a pivot end to a body of the vehicle by a first pivot connection and coupled at an output end to a closure panel device by a second pivot connection, the lever body for driving the closure panel device; the control member having a control connection coupling the control member to the lever body, the control connection moveable between the first pivot connection and the second pivot connection such that the lever body has an opening to provide a releasable engagement of the control connection between the lever body and the control member.

An apparatus for controlling bus doors (14, 16) that are arranged as a pair of doors that move in coordinated relation between door open positions and door closed positions, enables passengers to access an interior area (12) of a bus (10). The apparatus includes an actuator (28, 226). The actuator includes a drive lever (34, 228) that is selectively rotationally movable between rotational positions in which both of the doors are in the open positions and in the closed positions. Exemplary arrangements include at least one controller (128) that is operative to prevent the doors from causing damage to or from being damaged by engagement with obstructions. The controller further enables a bus driver or other authorized user to control access to the interior area of the bus using a user mobile device (144).

The present invention relates to a refrigerator and, more specifically, a refrigerator which enables a user to easily open a door thereof. The present invention relates to a refrigerator and method for controlling the same, which can prevent a door thereof from opening by itself due to a malfunction. According to an embodiment of the present invention, a refrigerator may comprise: a cabinet having a storage chamber; a door for closing or opening the storage chamber; a sensor provided to sense whether a user is within or out of a sensing distance, to enable discrimination between sensing-on and sensing-off; a door opening device provided to automatically open the door; and a control unit for determining an operation condition of the door opening device on the basis of a time interval from the sensing-on to the sensing-off and a duration for which the sensing-on continues in the sensor, so as to control the operation of the door opening device.

A swing door operator for moving a door leaf between an open and a closed position is described, the swing door operator including at least one drive unit that has a motor and a spring, the motor and spring being arranged to interact to enable moving the swing door leaf between the open and closed positions. The swing door operator also has a control unit that is operatively connected to the drive unit and thereby to the motor and that controls different modes of door operation.

An automated door assembly for a dishwasher appliance includes a door frame pivotally mounted to the cabinet. An extension arm is mounted to and extends away from the door frame at approximately 90 degrees. A motor is mounted to the cabinet and is coupled to a distal end of the extension arm by a cable. The motor is selectively rotated to wind and unwind the cable to move the door frame between the closed position and the open position. A latch assembly engages a striker mounted on the door frame to initiate the opening and closing process.

A refrigerator comprising a door rotatable about a hinge shaft. A door opening and closing apparatus comprises a drive motor, a first gear configured to receive power from the drive motor, a second gear, spaced apart from the first gear, configured to transmit a rotational force to the hinge shaft, a clutch gear configured to be rotatable around a rotation axis of the first gear, and configured to transmit power of the first gear to the second gear based on a position of the clutch gear around the rotation axis of the first gear, and a position detection sensor configured to detect the position of the clutch gear so that while the clutch gear is at the position, the clutch gear transmits the power received from the first gear to the second gear which transmits the rotational force to the hinge shaft to open and close the door.

An exemplary method involves operating a door operator coupled to a door. The door operator includes a motor operable to move the door in at least one direction and a controller operable to control the motor. The method generally involves a calibration procedure including: with the door at a first position and the door having an initial speed, initiating, by the controller, measurement of a time duration; in response to the door reaching a target speed different from the initial speed, ceasing, by the controller, measurement of the time duration; and determining, by the controller, a maximum speed based on the time duration. The method further includes performing at least one operation based upon the maximum speed.
