The chute safety system can comprise a bovine enclosure defined by a space between the rear gate assembly, the first side enclosure, the second side enclosure, and the front gate assembly. The rear gate assembly comprises a rear gate crossbar having a crossbar distal end and a crossbar proximate end, a crossbar hinge and a crossbar rotational axis.

A latch module for controlling an opening and a closing of a door of an appliance includes a latch, a spring that applies an elastic force to the latch, a motor; and a cam that contacts a contact surface of the latch and is coupled to the motor to drive the cam to pivot the latch. The cam includes a first radius, a second radius, and a third radius in a circumferential direction at an outer circumference of the cam. The latch is positioned at a first basic position when the first radius of the cam contacts the contact surface of the latch, positioned at a second basic position when the second radius of the cam contacts the contact surface of the latch, and positioned at a third basic position when the third radius of the cam contacts the contact surface of the latch.

A hydrodynamic water blocking device for an underground garage includes a water blocking plate assembly and side rail assemblies, wherein the water blocking plate assembly includes a first water blocking element, one end of the first water blocking element is rotationally connected with a base, the other end of the first water blocking element is rotationally connected with one end of a second water blocking element, the first and second water blocking elements have foamed layers, the base has grooves capable of accommodating the embedded foamed layers, water inlets formed in the base communicate with the grooves, each of the side rail assemblies includes a side plate with an ascending rail including a horizontally disposed linear rail and an arc-shaped lifting rail, the second water blocking element has a walking assembly embedded in the ascending rail which is connected with a driving mechanism installed at the second water blocking element.

A door monitoring system may include an optical sensor that may generate sensor signals indicative of a field of view of the optical sensor. The field of view may include at least part of an interior vehicle floor in front of a vehicle door. The system also may include controller that receives the sensor signals and that detects a presence or absence of one or more persons and/or objects within the field of view of the optical sensor. The controller may change a speed at which the vehicle door moves based on the presence or the absence of the persons and/or objects that are detected responsive to detecting the presence or absence of the persons and/or objects.

An apparatus comprises a baseplate configured to be coupled to a door movable between an open position and a closed position. A motor with circuitry electrically coupled to the motor, and configured to be in communication with a remote computing device. At least one proximity sensor is electrically coupled to the circuitry and configured to determine the door position with respect to a door frame. A drive wheel is coupled to the motor and the circuitry. The drive wheel has an external surface, and the external surface of the drive wheel is configured to rotatably contact a ground surface. The motor is configured to be remotely activated by the remote computing device to actuate the drive wheel to rotatably contact the ground surface to reposition the door responsive to receipt of a signal.

An aircraft panel system including a first panel, having a hinged coupling configured to couple the first panel to an aircraft structure, a second panel disposed adjacent to the first panel such that the first panel and the second panel together form cabin surface of an aircraft, and a latch mechanism configured to releasably couple the second panel to the aircraft structure, where the first panel is configured to pivot about the hinged coupling from a latched position to an actuation position to actuate the latch mechanism and cause a release of the second panel from the latch mechanism.

The present invention provides a refrigerator, comprising a refrigerator body and a door body. A hinge body is disposed on the refrigerator body. A first hinge shaft and a second hinge shaft are disposed on the hinge body. A first guide groove and a second guide groove are formed in the door body. The first hinge shaft is located in the first guide groove and the second hinge shaft is located in the second guide groove. During opening of the door body, the first guide groove moves relative to the first hinge shaft and the second guide groove moves relative to the second hinge shaft, the first hinge shaft applies an acting force to the first guide groove to drive the end, away from the first guide groove, of the second guide groove to approach the second hinge shaft, so that the door body is displaced in a horizontal direction.

A fire protection fastening device for fastening a door actuator, includes a frame with a back side, which is to be oriented to a mounting surface, in particular to a door, casing or wall, wherein a mounting axis is defined vertically to the back side. The frame is formed for arrangement between a door actuator and the mounting surface or is an integral component of the door actuator (102), at least one reaction chamber formed in the frame, wherein the frame delimits the reaction chamber on the entire circumference. The reaction chamber is open on the back side and/or on a front side of the frame opposite the back side. The device further includes a drive element made from thermally intumescent material disposed in the reaction chamber and, when activated, is formed for pushing away the door actuator from the mounting surface.
