The present invention relates to a sectional lifting door system. When the system is in normal operation, a door operator drives a cable drum to wind or unwind a cable for lifting or lowering slats. During a process of lowering the slats, if the slats is stopped or slowed unexpectedly (e.g. the slats hit an obstacle below), the door operator is disconnected from a shaft automatically. At this time, even if the door operator is still activated, the shaft does not rotate, the cable drum does not unwind the cable so that a certain tension force can be maintained on the cable and that the cable is prevented from loosening from the drum, thereby preventing the slats from falling off. Also, it can avoid the situation that the weight of the slats is completely applied to the obstacle because the cable drum continuously unwinds the cable.

Provided is a vehicle including: an image acquisition unit; a cap provided on a body of the vehicle and configured to open and close a replenishing port for replenishing an energy source; a driving unit allowing the cap to be separated or connected from/to the body; and a controller configured to determine an intention of a user to replenish the energy source on the basis of an image acquired by the image acquisition unit, and control the driving unit such that the cap is automatically separated from the body in response to determining that the intention of the user to replenish the energy source exists.

A device for controlling a door of a vehicle includes a drive unit that pivots the door between closed and open positions, wherein the closed and open positions define a pivoting range of the door. The device includes a control unit to control the drive unit. The device also includes a sensor unit that monitors the pivoting range. The sensor unit transmits a collision signal when an object is in the pivoting range while the drive unit is pivoting the door. The control unit transmits a switch-off signal to the drive unit if the control unit receives the collision signal.

A method and apparatus that prevent a collision with a hitch accessory are provided. The method includes: detecting an input to open a gate or detecting a gate opening motion, determining whether hitch accessory is present in a path of the gate opening motion, and in response to determining that the hitch accessory is absent from the path, opening the gate.

A powered hinge assembly includes a first gate hinge feature, a drive unit connected to the first gate hinge feature and a controller configured to displace the first gate hinge feature to an installation position upon connection to a power source. A powered tailgate assembly, incorporating the powered hinge assembly, and a method of installing a tailgate are also disclosed.

A refrigerator comprises: a cabinet including a storage compartment, a door opening or closing the storage compartment, a door opening device including a push rod moving from an initial position to a door opening position for opening the door and a motor providing power to the push rod, and a controller controlling the motor. The controller allows the motor to rotate at a first opening speed for opening the door of the refrigerator. The controller changes a rotation speed of the motor to a second opening speed lower than the first opening speed before the push rod contacts the door of the refrigerator or the cabinet.

An open roof assembly for use in a vehicle roof comprises a moveably arranged closure member and a drive system operatively coupled to the closure member for moving the closure member along a motion trajectory. The drive system comprises an electric motor and a control unit for controlling operation of the electric motor. The control unit comprises a mathematical model describing at least a part of the drive system; model parameters and a motion reference field. The control unit is configured to update the model parameters based on a received value of a first drive system variable; determine a value of a second drive system variable using the mathematical model; determine a comparison value by comparing the value of the second drive system value and a corresponding reference value of the motion reference field; and detect presence of an obstruction if the comparison value lies outside a predetermined value range.

A method (1000) for testing of a door operator (100), the door operator (100) being configured to via a mechanism (104) move at least one door leaf (200) between a first position and a second position. The door operator (100) includes a first drive unit (102) configured to optionally move the door leaf (200) into said first position and a control unit (103) connected to a sensor (105). The method includes the steps of initiating a simulated powerless mode, measuring operation of the door leaf by the sensor, and comparing measured values of movement with reference values.

An apparatus and a method for controlling and confirming a window are disclosed. An apparatus for controlling and confirming a window position, includes an input dial including a jog dial or a wheel dial and configured to input an input signal in response to a dialing operation by a user, a window configured to be opened or closed by a magnitude of the input signal inputted by the input dial, and a position confirming device configured to inform the user of a current window position in a tactile manner.

An automotive vehicle includes a closure arranged relative a closure frame to selectively cover an opening to the vehicle. The vehicle also includes an actuator configured to move the closure among a plurality of positions including open and closed positions, and a first sensor configured to detect motion of the closure among the plurality of positions. The vehicle additionally includes a latch assembly with an engaged state to retain the closure in the closed position and a disengaged state to permit the closure to move among the plurality of positions. A second sensor is configured to detect the engaged or disengaged state of the latch assembly. The vehicle further includes a controller which is configured to, in response to the first sensor detecting motion of the closure among the plurality of positions and the second sensor detecting the latch assembly in the engaged state, provide a diagnostic signal.
