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).

A household appliance includes a housing, a door pivotably connected to the housing, a cable connected to the door, a roller in contact with the cable, and a motor configured to drive the roller to move the cable such as to effect a pivoting movement of the door.

The disclosure relates to motor type hinge apparatus for a door, which can reduce load of a motor when a door of a washing machine is opened and closed, and of opening and closing the door even with less load of the motor. The motor type hinge apparatus includes a housing provided at a main body of an appliance that is equipped with a door, a motor assembly including a shaft, a joint, and a motor, a cam provided in the housing, and including a first hole and a second hole respectively formed at first and second ends thereof, a cam link including a second link hole and a first link hole respectively formed at first and second ends thereof, and a lever including a lever hole, a rod, and first and second steps.

The invention relates to a control device for controlling an externally-powered window lifter with anti-trap protection for a motor vehicle window. A control device of this type is designed to determine that an operating element for closing the window is actuated and, in response thereto, the window is moved in the closing direction. The control device is further designed to determine that the functional activity of the anti-trap protection is no longer guaranteed. In the case of a control device and in the event that it has been determined that the functional activity of the anti-trap protection is not guaranteed, the window lifter is actuated in response to the actuation of the operating element in such a way that the window is moved at a lower displacement speed in the closing direction when compared with the displacement speed with guaranteed functionality. In the case of an alternative control device and in the event that it has been determined that the functional activity of the anti-trap protection is not guaranteed, the window lifter is actuated in response to the actuation of the operating element with a predetermined actuation sequence of the window lifters in such a way that the window is displaced in the closing direction starting from the idle state.

A rim strike assembly includes a strike body, strike jaw, retaining clutch, locking cam, locking clutch, and a solenoid. The strike jaw, retaining clutch, locking cam, and locking clutch are pivotably coupled to the strike body. The strike body and strike jaw define a latch cavity to receive a latch of a door. The strike jaw includes a jaw follower. The strike jaw is pivotable between a release position and a closed position. The retaining clutch engages the jaw follower and includes a retaining follower. The locking cam includes a retaining notch and a locking notch. The retaining follower engages the retaining notch. The locking clutch includes a locking follower that engages the locking notch of the locking cam. The solenoid includes a plunger coupled to the locking clutch such that movement of the plunger rotates the locking clutch from a locked position to an unlocked position.

The present invention includes a height raising member body mountable to an upper end of a frame disposed above an entrance of a car that moves up and down through an elevator shaft, in which a rail for guiding a car door in an opening and closing direction and a pulley for use in opening and closing drive of the car door are mounted to the frame. The height raising member body characteristically includes: a base part connectable to the frame; and a supporting part capable of supporting the motor at a position upward away from the base, the motor being configured to drive the pulley via a belt.

A gatebox system for delivering fire retardant fluid from a firefighting aircraft. A first and second gate opening are formed through a lower portion of a gatebox. The gates are hingedly connected along edges of the openings. One or two drive shafts in the gatebox are rotatable in gates-closing and gates-opening directions. Crank arms are fixed to the drive shafts and coupled to the gates by connecting links, which define an over-center geometry while the gates are at a closed position, such that weight of the fluid on the first gate induces torque on the drive shaft in the gates-closing direction. Rotation of the drive shafts in the gates-opening direction enables control of the fluid flow from the hopper according to an angular position of the drive shaft.

A method for operating a boarding system for a vehicle includes reading in an inclination signal. The inclination signal represents an inclination of the boarding system relative to a reference. The method also includes reading in at least one movement process of at least one boarding element of the boarding system representing process signals and includes determining an operating signal for operating the boarding system using the inclination signal and the at least one process signal.

An entrance system is disclosed which has a movable door member having a door leaf with a first vertical edge and a second vertical edge. A sensor unit monitors a zone at or near the door leaf for presence or activity of a person or object, and captures an image of an external object at the first vertical edge of the door leaf, and processing the captured image to identify an optical code and recognize a learning mode trigger instruction encoded therein. Triggered by the recognizing of the learning mode trigger instruction, a learning mode of the sensor unit is automatically entered into, in which a distance between the sensor unit and the external object at the first vertical edge is automatically measured and a field width parameter value of the sensor unit is set based on the measured distance.
