A pneumatic control device of auto door includes a first directional control valve configured to control a direction of a compressed air supplied to a door cylinder for opening and closing a door, a door detection sensor configured to detect an open/close state of the door, first and second exhaust lines respectively connected to first and second outlet ports of the first directional control valve, and second directional control valves installed in the first and second exhaust lines respectively to operably exhaust the compressed air exhausted from the first and second outlet ports according to an emergency stop signal, and capable of changing positions to reduce an exhaust speed of the compressed air in case that the door is not completely open or closed when an operation signal is generated after the emergency stop 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 window control system includes a switch and a motor controller. The switch is manipulated by an operator and transmits signals based on the manipulation. The motor controller receives signals from the switch, determines a preset position from the signals, and commands a motor to move a window to the preset position. The preset position is one of at least three preset positions either programmed by a manufacturer or customized by the operator.

A window control apparatus of a vehicle and a method thereof may include a sensor that collects state information of the vehicle, and a controller that subdivides an entire short drop section of a frameless window provided in the vehicle into a plurality of short drop sections, and performs a transition of the frameless window between a full closed state of the frameless window and a plurality of shot drop states corresponding to the plurality of shot drop sections, based on the state information of the vehicle.

An apparatus of controlling a safety power window of a vehicle and a method thereof to not injure the body caught in a window frame, as well as to prevent a malfunction of the safety power window, by adaptively setting an operation reference value of the safety power window, may include a learning device that deep-learns a model which predicts an operation reference value of the safety power window provided in the vehicle, based on driving information of the vehicle, a sensor that collects the driving information of the vehicle, and a controller that obtains the operation reference value of the safety power window corresponding to current driving information of the vehicle by use of the model on which the deep learning is completed, and controls the safety power window according to the operation reference value of the safety power window.

A door operating apparatus for use with a door pivotably mounted to a door frame permits the door to swing in one of a manual operation and an automatic operation. The apparatus includes a housing, a first rotatable sprocket disposed in the housing and coupled to the door, a second rotatable sprocket disposed in the housing and connected to the first rotatable sprocket by a roller chain, the second sprocket having a top face with a protrusion, a drive assembly disposed in the housing and having a motor operably connected to a drive arm. A force applied to the door permits the first and second sprockets to rotate simultaneously to enable the door to swing open. Activation of the motor allows the drive arm to contact the protrusion and drive the second sprocket, thereby rotating the first and second sprockets simultaneously to enable the door to swing open.

A rotary actuator assembly, a household appliance having same and a control method therefor. The rotary actuator assembly comprises an object to be rotated and a rotary actuator configured to match said object. The rotary actuator comprises an output shaft and a driving mechanism for driving the output shaft to rotate. Said object is provided with a shaft hole matching the output shaft. The output shaft and the shaft hole of said object are internally provided with a driving structure and a butt joint structure matching each other in the circumferential direction. A resisting surface and a butt joint surface for pushing said object to move during the rotation of the output shaft are formed between the driving structure and the butt joint structure. A rotation space for manual operation of said object is formed between the driving structure and the butt joint structure.

A safety device with a safety switch and an actuator that is arranged movably relative to said safety switch. A transponder is arranged in the actuator, and a reading unit is arranged in the safety switch. A locking position of the actuator is controlled by the fact that transponder signals of the transponder are detected in the reading unit. The safety switch has a locking element with an influencing element. The actuator has a sensor coupled with the transponder. In the locking position of the actuator the locking element is insertable into a receptacle of the actuator. This effects the locking of the actuator. This locking is controlled in that the influencing element is only within the range of influence of the sensor when the locking element is inserted into the receptacle. Said sensor generates a sensor signal via which the transponder signals sent by the transponder are modified.

A modular channel for a door including an elongated channel forming at least a portion of an internal frame for the door. The elongated channel has opposing sides and a base member extending between one edge of each side. The modular channel includes a pair of parallel slotted openings along the base member and a channel adapter including a tabs corresponding with the pair of slotted openings. The tabs include a locking protrusion extending from tab. The tabs slidably engage the slotted openings and the locking protrusions engage the slotted openings when the tabs are urged fully into the slotted opening. The slotted openings may be positioned parallel with the elongated channel length and the elongated channel may include at least one transverse slot perpendicular to the slotted openings. The channel adapter may include a curved locking tongue disposed perpendicular to the tabs and engagable with the transverse slot.

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.
