A door operation apparatus for a vehicle is provided to open or shut a door at a speed corresponding to a user's force or information selected by the user. In particular, the door operating apparatus installed in a body to open and shut an internal room of the body includes: a power member connected to the door for applying a moving force to the door; a detector for detecting a force applied by the user to the door; a controller for determining an open and shut speed corresponding to the detected force and controlling the power member to be driven to open and shut the door at the determined open and shut speed; and a driver for driving the power member based on a command from the controller.

A clutch mechanism for coupling and uncoupling an electric motor and leadscrew has dog-clutch gears that can be engaged by a linear actuator, bell crank, and linkage shaft. Uncoupling force due to narrowed dog teeth are resisted by the alignment of the linkage shaft with the central portion of the bell crank.

An opening apparatus for a motor vehicle door element, having an electric drive and an actuating means, wherein the actuating means can be displaced by means of the drive and a gear mechanism arranged between the actuating means and the drive, such that a movement of the door element can be made possible, and a sensor for detecting the door movement, wherein at least one gear mechanism component is pivotably received in the opening apparatus, and the pivoting movement of the gear mechanism component can be detected by means of the sensor.

A safety barrier assembly is provided for a parking garage is positioned in proximity to an opening for a VRC and includes a horizontal AGV safety beam and upper and lower pedestrian barriers having horizontal railings and vertical legs. The vertical legs are telescoped into openings at opposite ends of the AGV safety beam. The vertical legs of the upper pedestrian barrier are longer than those of the lower pedestrian barrier. The AGV safety beam can be moved vertically between a lower position where the AGV safety beam is substantially adjacent a floor of the parking garage and an upper position where the AGV safety beam is elevated from the floor. The horizontal railings of the pedestrian barriers are parallel to and spaced above the AGV safety beam in the lower position. However, the horizontal railings abut the AGV safety beam in the upper position.

A control arrangement for an entrance system has one or more movable door members and an automatic door operator for causing movements of the one or more movable door members between closed and open positions. The door members comprise one or more swing doors. The control arrangement comprises a controller and a plurality of sensors. Each sensor is connected to the controller and is configured to monitor a respective zone at the entrance system for presence or activity of a person or object. Each sensor has an active mode and an inactive mode, wherein the sensor consumes no electric power in the inactive mode or substantially less electric power in the inactive mode than in the active mode. The controller is configured to determine a current operational state of the entrance system among a plurality of possible operational states, and selectively cause at least one of the sensors to be in its active mode or in its inactive mode depending on the determined current operational state of the entrance system.
