A door opening and closing device for a refrigerator includes a door coupled by means of a hinge unit to a main body defining a storage compartment therein, a gasket disposed between the door and the main body to provide a hermetic seal therebetween, and an opening and closing unit for opening and closing the door with respect to the main body, wherein the opening and closing unit includes a drive unit for generating a driving force, a gasket separation mechanism for pushing the main body using rotational force transmitted from the drive unit to separate the gasket from the main body or the door, and a door rotating mechanism for rotating the door using the rotational force transmitted from the drive unit.

A machine tool includes: a cover; a door; a drive mechanism; a detection unit; and an operation panel that receives an operation for the machine tool. A control device of the machine tool performs: processing to control the drive mechanism such that the door is opened, based on the operation panel receiving a first opening operation; processing to obtain an actual position from the detection unit and store the actual position as an opening position of the door, based on the operation panel receiving an operation to determine a position; and processing to control the drive mechanism such that the door is located at the opening position, based on the operation panel receiving a second opening operation. An opening speed of the door during the first opening operation is slower than an opening speed of the door during the second opening operation.

A vehicle lock includes a locking mechanism with a rotary latch and a pawl for latching the rotary latch when the vehicle lock is in a closed state, a receiver for receiving a reference code, a code transfer interface for obtaining an access code and a control unit which is configured such that the vehicle lock assumes an unlocked state when the obtained access code matches the reference code. The locking mechanism is used in a method for access-controlled loading and/or unloading of a vehicle. A high degree of automation of an access-controlled process for loading and/or unloading a vehicle can thus be achieved substantially with the aid of the vehicle lock.

A truck is provided that includes a bed section located rear of a cab section. The bed section is bounded on each side by opposing first and second upward-extending sidewalls, respectively. The truck also includes a truck bed cover that sits over the bed section on at least the first and second upward-extending sidewalls, and includes a door portion to create selective accessibility to the bed section of the pickup truck. The door portion is movable with respect to the first and second upward-extending sidewalls between open and closed positons via an automatic bed cover drive assembly that moves the door portion between open and closed positons according to a plurality of velocities within a predetermined variance.

A door operator and a method for moving a door leaf between a closed and open position utilize a drive unit, a control unit, and a supervise unit. The drive unit is connected to and moves the door leaf between the open and closed position. The control unit is connected to and controls the movement of the drive unit. The supervise unit includes a status management unit and one or more sensors that provide sensor data associated with an operation of the door leaf. The status management unit receives the sensor data from the one or more sensors, determines a status pattern from a plurality of status patterns of the operation of the door leaf at least based on the sensor data, with a first status pattern being associated with a status event, and triggers the status event in response to the first status pattern.

A vehicle door arrangement includes a first closing element arranged on a vehicle door and a second closing element arranged on a bodywork of the vehicle. The first and closing elements can be connected to each other in a positive looking manner to hold the door on the bodywork. A door handle is connected to a sensor for detecting a pressure input or a pulling input of a user on the door handle. The sensor is connected to a control unit, which controls a locking actuator and a door opening actuator. The locking actuator separates the first and second closing elements, and the door opening actuator opens the vehicle door relative to the bodywork. The control unit controls the locking actuator to separate the first closing element and the second closing element in response to a detected pressure input or pulling input, and to control the door opening actuator to open the door relative to the bodywork.

A vehicle control system includes: a service arrangement information acquisition unit which acquires service arrangement information including identification information of at least either one of a person in charge of a service who executes a predetermined service that targets a predetermined vehicle and a service vehicle used when executing the predetermined service; a surrounding object recognition unit which recognizes an object present in an area around the predetermined vehicle; and a service reception handling unit which executes predetermined processing for receiving the predetermined service in a case where the object is determined as the service vehicle or the person in charge of the service by an object authentication unit.

A retrofit module configured for use with a door closer having a pinion. The retrofit module generally includes a case, an output shaft, a motor, and a control assembly. The output shaft is rotatably mounted in the case, and is configured for rotational coupling with the pinion. The motor is mounted to the case, and is operable to rotate the output shaft in a door-opening direction. The control assembly is mounted to the case, and is configured to operate the motor to drive the output shaft in the door-opening direction in response to an actuating signal.

The present invention includes: a vehicle exterior image acquisition unit acquiring a vehicle exterior image being an image of an external surrounding of a vehicle; a vehicle interior image acquisition unit acquiring a vehicle interior image being an image of an interior of the vehicle; a person recognition unit recognizing, based on the vehicle exterior and interior images, respective motions of a person outside the vehicle and a person in the vehicle; and a door control unit controlling a state of a door of the vehicle, wherein, if a person outside the vehicle approaching the vehicle has been recognized based on a recognition result of the person recognition unit, if the person in the vehicle has performed an instruction motion indicating any seat of the vehicle, the door control unit executes an opening operation on the door corresponding to the seat indicated by the instruction motion.

The present invention includes: a vehicle exterior image acquisition unit acquiring a vehicle exterior image, a vehicle interior image acquisition unit acquiring a vehicle interior image, a person recognition unit recognizing, based on the vehicle exterior and interior images, a presence of a person in the vehicle and a motion of a person outside the vehicle, a door control unit controlling a state of a door of the vehicle, and a motion determination unit determining a specific motion to be carried out when the person outside the vehicle instructs an opening operation of the door, wherein the door control unit executes the opening operation when the person outside the vehicle has performed the specific motion, if the presence of a person in the vehicle has been recognized based on a recognition result of the person recognition unit.
