The invention is an automated window mechanism having an electric motor attached to a sliding panel of a window configured to open and close the window by moving the sliding panel. The electric motor has a locked state in which the electric motor and sliding panel are stationary. The automated window mechanism also includes a monitor configured to detect an external force applied to the sliding panel while the electric motor is in the locked state. In response to the monitor detecting the external force while the electric motor is in the locked state the positive lead and the negative lead to a same electric potential thereby rendering the electric motor an electric brake impeding the external force from moving the sliding panel. A method and system for preventing unwanted movement of an automated window are also disclosed.

Embodiments of a system for controlling a vehicle power tailgate are described. The system includes a motor operably connectible to a tailgate to open and close the tailgate, a processor, and a memory communicably coupled to the processor. The memory stores a tailgate control module including instructions that when executed by the processor cause the processor to, responsive to a value of a motor speed parameter being above a predetermined motor speed threshold and a value of a motor acceleration parameter being above a predetermined motor acceleration threshold during opening of a tailgate, control operation of the motor to apply a braking force to the tailgate.

The present invention relates to a symmetrical and reversible-clutch mortise lock comprising a central follower, a pair of symmetrical lateral followers, each one located on one side of the central follower to be activated by square bars of handles, a spacer which makes the movement of the two lateral followers independent and a motor, which connects to an actuation lever and which is activated when an access code is validated. The lock further comprises a clutch housed and guided in an accumulator arm able to move linearly to be housed in both lateral followers such that the corresponding lateral follower, when activated by the motion of the door handle, pushes the clutch until it makes contact with the central follower and activates the latch of the lock.

An overhead door opener for opening and closing an overhead door. A motor is coupled to a shaft and is configured to rotate the shaft to raise and lower the overhead door. The shaft is coupled to the overhead door. The overhead door opener also includes a one-way bearing coupling the motor to the shaft, wherein the one-way bearing is configured to transmit torque from the motor to the shaft, and not to transmit torque from the shaft to the motor.

An anti-collision system and an anti-collision method are disclosed. The anti-collision system includes a first circuit and a magnetic device arranged on the door body and the door frame respectively, the first circuit includes a first power source, a first coil, and a first switch circuit connecting the first power source and the first coil; when a speed sensor detects that the rotation speed of the door body is too high, a control terminal controls the first switch circuit to switch on, such that the first coil is connected to the first power source to generate a first magnetic field, which causes a repulsive force to reduce the rotation speed of the door; when the rotation speed of the door body is reduced to a preset value, the control terminal controls the first switch circuit to switch off, the repulsive force disappears, and the door body is closed smoothly.

A brake device for a drivable part, in particular for use for a vehicle flap, in particular in an automobile, includes a drivable load device (11) which can be radially brought into contact with a disc (90) of the drivable part, with a first holding position and a second release position. At least one brake element rests against the periphery (92) of the disc (90) in a frictional manner in the holding position and secures the disc (90) from rotating using a specifiable force. In the release position, the at least one brake element is arranged at a distance from the periphery of the disc (90) and allows a free run of the disc (90), and the load device (11) can be adjusted between the holding position and the release position, preferably by a motor (12). A brake device or a rotating drive with which a drivable part of the drive is secured against a displacement on the basis of the mass of the component to be displaced even when the motor is not being provided with power or is deactivated is achieved in that the first holding position and the second release position are each designed as a metastable holding position.

Disclosed herein is a sliding door system including a motor, a driveshaft coupled to the motor, and a coupling mechanism fastened to the sliding door. The coupling mechanism is configured to convert rotation of the driveshaft into linear motion of the sliding door, such that movement of the coupling mechanism is directly correlated to movement of the sliding door. The sliding door system also includes a rotary encoder, a belt mechanically coupled to the coupling mechanism. The belt, as moved by the coupling mechanism, is configured to turn the rotary encoder as the sliding door moves, such that movement of the rotary encoder is directly correlated to movement of the sliding door and not directly correlated to movement of the motor and driveshaft.

A door stop for a door includes a clamp that is securable over a first side edge of a door. The clamp has a guide. An arm has a receiving portion for receiving the guide to permit movement of the arm on the clamp between an open position and a closed position. A spring mechanism is operably coupled to the clamp and the arm, and urges the arm on the guide of the clamp toward the closed position. In the closed position, the arm prevents the door from engaging with a respective door jamb.

A vehicle door control device applied to a vehicle including a swingably supported door and a door braking unit applying a braking force to the door includes: a braking control unit that executes a first braking processing of holding the braking force at a reference braking force for stopping the door and ending when an external force acting on the door is larger than the braking force, and a second braking processing of gradually increasing the braking force from the reference braking force after the first braking processing. The braking control unit executes, during execution of the second braking processing, a processing of eliminating the braking force when a situation where the external force is larger than the braking force continues, and executes a third braking processing of holding the braking force to be equal to or larger than the reference braking force when the situation does not continue.
