A latch module incorporated with an automatic opening function and a secure lock function includes a latch, a spring that applies a force to move the latch in a first direction, a drive to move the latch in a second direction, a cam that transmits power of the drive to the latch, and first and second switches that are turned on and off by the cam. The first and second switches are in a first mode in which the two switches are turned on and the latch is disposed at a manual lock position, a second mode in which the first switch is turned on and the second switch is turned off and the latch is disposed at an opening position, a third mode in which the first switch is turned off and the second switch is turned on and the latch is in a secure lock position.

An unmanned aerial vehicle airport, an unmanned aerial vehicle system, a tour inspection system and an unmanned aerial vehicle cruise system. The unmanned aerial vehicle airport comprises a support base, a parking apron, a protective cover and a protective cover opening and closing driving device. The parking apron is installed on the top of the support base; the protective cover covers the top of the apron; the protective cover opening and closing driving device is installed between the support base and the protective cover, and the protective cover opening and closing driving device is configured to cause a bar linkage mechanism to drive the protective cover to switch between an open position and a closed position. The unmanned aerial vehicle airport is provided with the protective cover for the parking apron. If the protective cover is open, the unmanned aerial vehicle is parked on the parking apron, and takes off from the parking apron.

A system for operating at least one magnetorheological fluid clutch apparatus may, in a first mode, vary an amount of torque transmission between a driving member and a driven member in the at least one magnetorheological fluid clutch apparatus by actuating at least one coil in the at least one magnetorheological fluid clutch apparatus. In a second mode, the system may cause torque transmission between the driven member and the driving member by setting a desired remanent magnetization level in a magnetic component of the at least one magnetorheological fluid clutch apparatus by actuating the at least one coil in the at least one magnetorheological fluid clutch apparatus.

A door hinge apparatus of a vehicle may include a main bracket provided on one side of a vehicle body corresponding to an end portion of a door of the vehicle and having slide slots formed on upper and lower plates, respectively, a slide hinge bracket engaged to the slide slots to be slidable along the slide slots of the main bracket by a link mechanism, and a door hinge bracket Provided on the end portion of the door and pivotally connected to an external end portion of the slide hinge bracket through a hinge shaft.

The motorized drive according to the application is particularly suitable for auxiliary or emergency drives and is configured to open or close a wing of a barrier such as a door. The motorized drive includes a motor and a reduction unit through which the motor can open or close the wing, an auxiliary motor including a helical spring which is able to absorb mechanical energy during the opening of the wing and release it during the closing of the same, a reduction unit connecting the auxiliary motor to the wing. A first and a second toothed profile realize a gear with a variable transmission ratio. The first and/or the second toothed profile form at least one toothing having a pitch profile which is substantially non-circular or not formed by a simple arc of a circle or a straight line.

A method and a device for controlling door movements of a controllable door of a motor vehicle. A control device and a sensor arrangement are assigned to the door and the door has a controllable motion influencing device. A motion of a door wing of the door is controlled and influenced by the motion influencing device to alternate between a closed position and an open position. The motion influencing device includes a driving device with a drive motor. The sensor arrangement includes a current sensor which detects the motor current of the drive motor. While closing the door wing the control device detects an obstacle when the door wing is not yet closed and the power input of the drive motor rises above a predetermined threshold. Then the control device stops the drive motor.

Multi-mode personal transportation and delivery devices and methods of use are disclosed herein. A method can include providing a preview of an opening height of a tailgate to a user, where the opening height is defined by a distance of liftgate that is measured relative to a ground plane, receiving feedback to adjust the opening height, creating a customized liftgate opening height from the feedback, and storing the customized liftgate opening height in a user account.

A method of operating a motorized flap arrangement of a motor vehicle, the flap arrangement including a flap, configured to be swiveled about a swivel axis, a drive arrangement, a drive controller, configured to control the drive arrangement, and a motion sensor arrangement, the sensor values determined by the motion sensor arrangement are checked for fulfillment of a specified actuation criterion, upon which an actuation effect manually exerted on the flap is deemed to be detected and the drive arrangement is controlled by the drive controller for motorized adjustment of the flap. The motion sensor arrangement arranged on a section of the flap facing away from the swivel axis. The actuation criterion is defined in such a way that the actuation criterion is fulfilled by a torque introduced into the flap before exceeding a breakaway torque of the flap kinematics.
