Disclosed is a door system comprising: at least one travelable door element; at least one running rail for guiding the door element; and at least one light barrier element for detecting a free travel path of the door element, wherein the at least one running rail has a cut-out at or in which the at least one light barrier element is fastened.

A system and method for controlling motion of a door are provided. The door is moveable between an open position and a closed position and has a balanced position whereat the door does not move towards the open position nor the closed position under an effect of gravity. The system includes a power actuator for moving the door to a partially open position between the open position and the closed position. The power actuator is adapted to allow the door to move to the balanced position after the power actuator has moved the door to the partially open position.

The present invention relates to a method for determining the door position in a door system which has a rail for guiding a movable door element and a sensor element (10) for detecting a free movement path of the door element (50), the method comprising the steps of: detecting the state of the at least one sensor element (10), which can either be free of the door element (50) or covered by the door element (50), such that, in the event of a change in the state of the sensor element (10), the arrangement position of the sensor element (10) corresponds to the door element (50), and a door control lines the door position with the aid of this information.

An improved method and an improved apparatus for operating an automatic door system are distinguished by the following features, inter alia: — a sensor device (9) is used, which implements a monitoring region (19) assigned to and/or disposed upstream of the leaves (1; 1a, 1b) for the detection of objects (P, G) which are situated and/or moving in said monitoring region (19), — by means of the sensor device (9) and/or by means of the control and/or evaluation device (11), an object (P, G) situated in the monitoring region (19) is detected with regard to the position and direction of movement of said object and also with regard to the width, size and/or contour (K) or overall contour (23) of said object, and — depending on the movement-dependent position and direction of movement (21) and also the width, size and/or contour (K) or overall contour (23) of the detected object (P, G), the at least one leaf (1; 1a; 1b) is moved, in particular opened, readjusted and/or closed, in an object-related manner.

The invention relates to a system for controlling access to a restricted area in a building, which system has a sliding door system and a controller for the sliding door system. The sliding door system has a door frame and a sliding door which can be displaced by a drive unit actuated by the controller. The door frame has a passage region and a wall shell region which accommodates the sliding door in the open position. The sliding door has an end face which points toward the passage region in the open position. The controller has a processor unit and a sensor unit, the sensor unit is arranged on the end face and the processor unit is arranged between the door leaves. A recognition device captures and checks credentials presented by a user. If the credentials are valid, a record is determined in a storage device, in which the credentials are assigned to an opening width (W) of the sliding door, in order to trigger the movement of the sliding door according to said opening width (W). The controller is designed to recognize a gesture made by the user and to actuate the sliding door depending on said gesture in deviation from the opening width (W).

Door operator (10) for an overhead door system (400), said door operator (10) being configured to move a door (401) of said door system (400), comprising: a first electric motor (100), a second electric motor (200), a planetary gearing (300), a control unit (11) configured to control the first (100) and second electric motor (200), and wherein the first electric motor (100) is connected to a first planetary gearing input shaft (301) and the second electric motor (200) is connected to a second planetary gearing input shaft (302), and wherein a planetary gearing output shaft (303) is associated with a shaft (402) for movement of the door (401).

Method of operating a lid of a robotic vehicle. The lid is operable by a motor between an opened and a closed positions. When the lid is between the opened position and a first intermediary position, a first electric current having a first value is provided to the motor for exerting a first force on the lid. When the lid is between the first intermediary position and a second intermediary position, a second electric current, having a second value whose sign is opposite to a sign of the first value, is provided to the motor for exerting a second force on the lid. The second force is applied in an opposite direction of the first force. When the lid is between the second intermediary position and the closed position, a third electric current having a third value having a same sign than the first value is provided to the motor.

An automated window mechanism is disclosed, including a motor secured to a window, the window being in a frame and wherein the motor causes the window to move relative to the frame in two directions: an open direction being defined as a direction toward which movement of the window relative to the frame causes the window to be more closed, and a closed direction defined as a direction opposite the open direction. The mechanism also includes a transmission component that transfers power from the motor to movement of the window relative to the frame, the transmission component having a backup defined as a distance the transmission component can move from a first point at which further movement in the open direction will cause the window to begin moving in the open direction, and a second point at which further movement in the closed direction will cause the window to begin moving in the closed direction. The mechanism also includes a processor and memory storing one or more computer-readable instructions executable by the processor to perform acts. The acts include instructing the motor to move the window relative to the frame, and upon the window reaching a desired position relative to the frame, reversing the transmission component into a neutral range within the backup to release energy stored in the transmission component.

An automatic door operator (30) for a swing door assembly (10) having a door leaf (14) rotationally supported by a door frame (12) is disclosed. The automatic door operator has a motor (34) for causing opening of the door leaf (14) with respect to the door frame (12), and a controller (31) being configured for performing different functions (60) of the automatic door operator. The controller (31) is configured to detect (42) a movement of the door leaf (14), not caused by the motor (34), identify (44) a predefined movement matching the detected movement, determine (46), among the different functions, a function (61-A, 61-B) being associated with the predefined movement, and perform (48) the determined function.
