A door opening and closing apparatus includes a rail module including: a rail member extending along a front-and-rear direction; a drive device mounted on the rail member; and a supporting member coupled to one end portion of a closing cable the other end portion of which is connected to the drive device and one end portion of an opening cable the other end portion of which is connected to the drive device. The rail module is provided with the drive device fastened to an outside of a vehicle body such that a part of the drive device goes inside the vehicle body through an opening provided on the vehicle body. A portion of a housing of the drive device located outside the vehicle body closes the opening while a sealing member is interposed therein.

A vehicular sensing system, a vehicle and a method of performing one or both of vehicular mapping and navigating operations using the sensing system. The sensing system includes one or more sensors, a retractable mounting structure secured to a roof of the vehicle to be selectively placed within a recess formed in the roof. The mounting structure and sensor cooperative with one another such that the mounting structure selectively moves the sensor between a stowed position and a deployed position. A fairing is used to cover at least a portion of the sensing system and the recess when the sensing system is stowed within the recess. In a deployed position, the sensor is extended away from the roof to permit the sensor to acquire mapping or navigation data, while in its stowed position, the sensor, mounting structure and fairing define aesthetically-pleasing and aerodynamically unobtrusive profile across the portion of the roof that corresponds to the recess.

A door system for a public transit vehicle with at least one door opening and a door that closes this door opening includes a sensor unit, which does three-dimensional and touch-free scanning of a passenger compartment in the area of the door opening and at least one communication element for the context-based communication with passengers based on readings by the sensor unit. A process for monitoring and controlling door systems of a public transit vehicle are also provided including the steps of touch-free and three-dimensional scanning of a passenger compartment in the area of a door opening with a sensor unit and measuring distances, shapes, and movements of objects by evaluating the readings of the touch-free and three-dimensional scanning. The process also includes issuing context-based information to affected passengers via a communications system, whereby the information is based on readings from the sensor unit.

a process for monitoring and controlling such a door system.

The present invention relates to the technical field of door closers, and particularly discloses an electromagnetic release door closer. The electromagnetic release door closer comprises a door closer body, a slide rail, and a rocker arm, one end of the rocker arm is articulated with the door closer body, wherein the slide rail is provided with a slide groove and a slide cavity which are parallel to each other, a through slot which is parallel to the slide groove is arranged between the slide groove and the slide cavity, wherein an electromagnetic limiting mechanism can be fixed at any position in the slide cavity. In the electrified state of an electromagnet, an electromagnetic attracting plate and the electromagnet are in a fixed state under the action of magnetic force, a limiting latch bolt is located in the slide groove, and is used to limit the sliding of a slider in the slide groove, and under this state, the slider can slide freely between the limiting latch bolt and one end of the slide groove, that is, a door leaf can move freely between a position limited by the limiting latch bolt and a maximum opening position. The defect that a door leaf can only be fixed in one specific state in the prior art is overcome, the range of adjustment is wider, and the electromagnetic release door closer is more convenient to use, and can meet more use requirements.

A holder to be attached to a vehicle window plate includes a bottom portion, a first side portion provided to extend in a first direction perpendicular to the bottom portion and a second side portion opposite to the first side portion. A value t/w is 1.5 or more when a smallest value of distances between end portions of the first side portion and end portions of the second side portion is expressed by w, and a distance between a central portion of the first side portion and a central portion of the second side portion is expressed by t.

A bimini top includes a framework and a canopy secured to the framework. The canopy is formed of a mesh material. The mesh material allows air to flow through the canopy to limit the stresses to the connected structure at high speed. The bimini top may secure a removable and reversible secondary canopy or cover that can provide rain and sun protection under the mesh canopy or may extend forward of the bimini frame when not subjected to high speeds.

A method for triggering at least one passenger protection means. The method includes a step of reading in a control signal which contains a command for carrying out an activation of the passenger protection means. Furthermore, method includes a step of releasing an activation of the passenger protection means as a response to the read-in control signal. Furthermore, the method includes a step of evaluating the control signal for the identification of the command for carrying out the activation of the passenger protection means and activating the passenger protection means as a response to an identified command for carrying out the activation of the passenger protection means to trigger the passenger protection means.

A refrigerator includes a cabinet including an outer case forming an external appearance and a storage compartment, a refrigerator door coupled to the cabinet to open or close the storage compartment, an installation bracket coupled to the outer case inside the outer case, a door opening device installed in the installation bracket outside the outer case and including a push member for opening or closing the refrigerator door, and a buffer member disposed a coupling portion between the door opening device and the installation bracket.

A door system for a public transit vehicle includes least one door opening and a door that closes this door opening, wherein a sensor unit performs three-dimensional and touch-free scanning of a passenger compartment in the area of the door opening. A process of monitoring and controlling such a door system includes the steps of touch-free and three-dimensional scanning of a passenger compartment in the area of a door opening with a sensor unit, and measuring distances, shapes, and movements of objects by evaluating the readings from touch-free and three-dimensional scanning.
