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.

Embodiments for an automated sliding door system having a slide and rail assembly engaged to a door panel for automatically sliding the door panel relative to a door frame are described. The slide and rail assembly is in operative communication with microprocessor that executes software to adjust various operational parameters of the slide and rail assembly to operate the automatic sliding door.

One embodiment relates to an exit device assembly. The exit device assembly includes a center case, a push pad movably mounted on the center case, and a mechanical case coupled to the center case, wherein the exit device includes an opening. The assembly also includes a sensor aligned with the opening, wherein the sensor is structured to detect a user from a distance through the opening and to generate an output signal in response to detecting the user. The assembly also includes a latch and a latch actuator. The assembly also includes a controller in communication with the sensor and the latch actuator, wherein the controller is structured to transmit an actuating signal in response to receiving the output signal from the sensor, wherein the latch actuator is configured to move the latch from the locked position to the unlocked position in response to the actuating signal.

An opening-and-closing body configured to open and close an opening moves across a first section in which the opening-and-closing body moves in the closing direction against its own weight and a second section in which the opening-and-closing body moves in the closing direction according to its own weight. The driver drives the opening-and-closing body in the closing direction continuously from the first section to the second section. The predictor predicts that the drive section of the opening-and-closing body will shift from the first section to the second section when the driver drives the opening-and-closing body in the closing direction toward the second section from the first section. The drive controller decreases the driving output of the driver for driving the opening-and-closing body in the closing direction according to the result of the prediction made by the predictor.

A vehicle door glass lifting device includes a lifting and lowering mechanism by which a door glass is lifted or lowered relative to a window frame of a vehicle door, a contact sensor that is arranged on a top end surface of the door glass and extended along a longitudinal direction of the top end surface of the door glass, and a control part that controls the lifting and lowering mechanism. The contact sensor can detect a contact state including a contact length with a contact object. The control part determines whether or not the contact object is a foreign object based on the contact state detected by the contact sensor, and the control part lowers the door glass when the contact object is determined as the foreign object.
