A method according to one embodiment includes generating, by at least one sensor, motion data indicative of motion of a door having a door closer as the door is moved from an open position to a closed position, analyzing the motion data to determine a duration the door was in each of a plurality of door movement zones between the open position and the closed position, determining at least one adjustment to the door closer for a successful installation of the door closer based on the duration the door was in each of the plurality of door movement zones, and displaying at least one installation instruction corresponding with the at least one adjustment on a graphical user interface of a mobile device.

A door closer may utilize a door closing device (e.g., spring) and a force adjustment device (e.g., a motor) in order to allow for manual door opening and assisted door closing. During operation, as a door is manually opened, the spring is loaded (e.g., compressed or tensioned) above its pre-loaded closed position state. Once manual opening is completed, the spring that is loaded during opening begins returning to the pre-loaded closed position state, and thus, moves the door automatically towards the closed position. Depending on the pre-loaded spring setting, the closing force of the door may not be enough to close the door, or to close the door with the preferred force. As such, during closing a controller may engage a motor not to drive the door directly, but to increase the pre-load of spring to increase the closing force in order to allow the door to close as preferred.

An apparatus and method for closing a car door from the inside of the car using an elongated handle and a hand mounted on the distal end, which is especially helpful for an aging individual and/or an individual with disabilities to easily close a car door without help from others and without having to exit the vehicle.

It is provided a window lifter assembly, comprising an adjustable window pane for a vehicle window lifter, in which the window pane in a closed state is flush with upper and/or lateral body parts which border a window opening, to be closed by the window pane, in a window frame. The window lifter assembly furthermore has at least one pane guide element which is fixed on the window pane in the region of a lateral pane edge and at least one frame-side guide element at which the pane guide element is held displaceably on the window opening. The at least one pane guide element is of multi-part design with at least one first guide part and a second guide part.

The invention relates to an automatic door system including a first door leaf of a first door leaf arrangement that can be displaced in the longitudinal direction. A floor-side guide rail arrangement extends in the longitudinal direction and includes a first floor rail arrangement. The at least one first door leaf includes an engagement element which is arranged on an underside of the at least one first door leaf. The at least one first floor rail arrangement includes at least one first floor rail and at least one connection and/or functional element, wherein the at least one connection and/or functional element is arranged on an end side of the at least one first floor rail. The at least one first floor rail includes at least one first guide groove extending in the longitudinal direction. The at least one engagement element of the at least one first door leaf of the at least one first door leaf arrangement is inserted into the at least one first guide groove and is guided in the longitudinal direction by the at least one first guide groove.

The present invention discloses a method for automatically detecting door or window faults, comprising the following steps: mounting a displacement sensor at at least one monitoring position of the door or window frame and leaf and/or door or window hardware to monitor a relative position change of the door or window frame and leaf and/or relative displacement of the hardware at said at least one monitoring position; and connecting the displacement sensor to a controller which judges whether the relative position change of the door or window frame and leaf and/or relative displacement of the hardware at said at least one monitoring position exceeds a displacement threshold, and thereby perform combined judgment for door or window faults. The present invention further discloses a mechanism for automatically detecting door or window faults. The present invention can automatically detect possible faults occurring during use of the door or window, and thereby eliminate hidden risks endangering the user and other persons' personal safety, and exhibit important social significance.
