A vehicle door hinge for a vehicle door opening vertically includes a first hinge part attached to a vehicle frame having a pivot attachment means, a second hinge part attached to the door attached to the pivot attachment means to allow the second hinge part to rotate the door in an opening or closing direction, a stopper part attached to the pivot attachment means at a distance from a mass centre of the stopper part, a locking mechanism for locking the stopper part position relative the second hinge part. The locking mechanism is moveable between an unlocked position and a locked position. The stopper part in the unlocked position is arranged to be moved by gravity to a resting position where it is adjacent or abutting the first hinge part and stopped by the first hinge part from rotating in the opening direction but free to rotate in the other direction.

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.

A system and method which allows automatic recognition of any of three common monitored motorized door or gate safety edges or other entrapment protection devices. The invention allows retrofitting existing motorized door operators without enough monitored input ports to allow for more monitored entrapment devices required on laterally moving motorized gates. The system interfaces with obstruction monitoring devices in normally closed, pulsed, or resistive termination operating environments found in entrapment protection systems. Firmware logically analyzes the state of each edge or entrapment protection device to select and direct an appropriate output signal for a motorized gate operator. An operational example is disclosed which provides for up to six different device inputs and two separate outputs for the motorized door operator, which can be configured through dual inline package switches allowing field configuration.

A movable wall panel system is disclosed. The movable wall panel system may include at least one monitoring system to monitor at least one area adjacent the movable wall panel system. The movable wall panel system may include a touch screen as part of an operator interface.

A sensor unit includes a garage door sensor, a frame configured to be secured at one side of an opening for a garage door, and a cover. The garage door sensor is connected to said frame. The cover is configured to accommodate at least a portion of said garage door sensor. The cover is removably secured to said garage door sensor, such as for periodic cleaning.

A leaning-against-vehicle door detection system includes an imager and a determination device. The imager has an image pickup range including a door of a vehicle and the vicinity of the door inside a vehicle cabin. The determination device determines whether or not there is a passenger or luggage leaning against the door, from an image picked up by the imager.

The invention relates, among other things, to a door sensor device (20) for mounting on a door element (10), more particularly a swing door, which can be rotated about an axis of rotation (D), having at least one transmission device (21) for generating at least one monitoring beam (S) in the direction of the floor, said beam being oriented at an angle to the door leaf plane (E) of the door element (10), at least one receiving device (22) for receiving reflected or back-scattered radiation, and an evaluation device (23) for evaluating the radiation received by the receiving device (22) and generating an object detection signal. According to the invention, the evaluation device (23) is designed such that it checks whether a predefined exclusion condition is met, wherein the exclusion condition is dependent on at least three values, specifically an angle value specifying the rotational angle of the door element (10), a maximum value predefined for the evaluation device (23), said maximum value specifying a fixed, maximum permitted rotational angle of the door element (10), and a measuring-point-specific advance angle value, which specifies the angle between a section which is bounded by the measuring point (M1-Mn) formed by the monitoring beam (S) on the floor and the axis of rotation (D) of the door element (10), and the door leaf plane (E).

A control arrangement (20) for an entrance system (10) has one or more movable door members (D1 . . . Dm) and an automatic door operator (30) for causing movements of the one or more movable door members (D1 . . . Dm) between closed and open positions. The control arrangement (20) comprises a controller (32) and a plurality of sensors (S1 . . . Sn). Each sensor is connected to the controller (32) and is configured to monitor a respective zone (Z1 . . . Zn) at the entrance system (10) for presence or activity of a person or object. Each sensor (S1 . . . Sn) 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 (32) is configured to determine a current operational state of the entrance system (10) among a plurality of possible operational states, and selectively cause at least one of the sensors (S1 . . . Sn) to be in its active mode or in its inactive mode depending on the determined current operational state of the entrance system (10).

Systems, apparatuses, and methods are provided herein that may be used to monitor a movable barrier operated by a movable barrier operator. In some embodiments, a system includes a camera configured to capture frames, and a control circuit. The camera has a field of view that defines a boundary of each of the frames. The control circuit is configured to receive a first frame, identify a stationary object in the first frame, and define a region of interest “ROI” relative to the stationary object in the first frame. The control circuit is further configured to receive a second frame, identify the stationary object in the second frame, determine whether at least a portion of the ROI is outside of the second frame, and cause the movable barrier operator to enter a failsafe mode upon the at least a portion of the ROI being outside of the second frame.

Examples of the disclosure relate to example systems and methods for operating a door opening system for a vehicle. An example system includes a motorized door, and a sensor configured to detect obstacles within a travel path of the motorized door. The system also includes one or more processors configured to receive a door control signal, and in response to the door control signal, determine whether an obstacle had been detected within the travel path of the motorized door. In response to determining that an obstacle has been detected, the one or more processors can block activation of the motorized door.
