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.

A cab for a work machine includes a cab body that is formed with a doorway, a door that is rotatably supported on the cab body so as to open and close the doorway, an actuator that generates a driving force to open and close the door, a rod that is attached to the door and rotatable relative to the door, and a sensor that is attached to the door separately from the rod. The sensor detects the motion of the rod relative to the door by detecting the motion of the rod relative to the sensor.

The present disclosure is to improve the durability of a device for detecting a foreign substance. The cab for a work machine includes a cab body that is formed with a doorway, a door that is rotatably supported on the cab body so as to open and close the doorway, an actuator that generates a driving force to open and close the door, a rod that is attached to the door and rotatable relative to the door, and a sensor that is attached to the door separately from the rod. The sensor detects the motion of the rod relative to the door by detecting the motion of the rod relative to the sensor.

A seal for a movable part of a motor-vehicle includes at least one body formed of polymeric elastomeric material supplemented with carbon-based nanofillers. The body includes an outer surface having one or more piezo-resistive areas where the polymeric material supplemented with carbon-based nanofillers is piezo-resistive due to laser irradiation to define one or more electric deformation sensors activatable in response to a contact with a foreign body during the movement of the movable part of the motor-vehicle. The body also includes one or more conductive lines made locally electrically-conductive due to laser irradiation to define the one or more electrical connection lines connecting the electric deformation sensors to electrodes associated with the seal.

A controller system is provided for a motorized moveable striker assembly on a vehicle door or window. The assembly includes a striker on the door post which is moveable by an electric motor between extended and retracted positions. A latch on the door releasably engages the striker. Switches in the latch sends signals to the controller to actuate the motor. After the latch is engaged, the controller retracts the striker from the extended position to fully close the door. When the latch is disengaged from the striker, the latch switch sends a signal to controller to actuate the motor so as to extend the striker from the retracted position to the extended position as to prepare for the next door closing. Anti-pinching control and temperature compensation is also provided.

A pinch detection switch includes a pressure sensing structure including at least one linear pressure sensing member with multiple conductor wires spaced apart from each other in an inner side of a tubular elastic body, and a tubular cover member to be attached to an end on a forward side in a moving direction of a movable body, and which is formed with a hollow portion which receives the pressure sensing structure. The pressure sensing structure includes a coating member which covers the at least one linear pressure sensing member, and which faces an inner surface of the hollow portion at both its ends in a width direction orthogonal to the moving direction of the movable body and an extending direction of the cover member. A position in the width direction of the at least one linear pressure sensing member in the hollow portion is defined by the coating member.
