A mmWave radar sensing system is operatively connected to the controller to indicate user presence. The controller includes machine readable instructions configured to verify gesture input from the gesture sensing system using input from the mmWave radar sensing system before controlling the actuator to open or close the lavatory door.

An automatic door operator (30) for a swing door assembly (10) having a door leaf (14) rotationally supported by a door frame (12) is disclosed. The automatic door operator has a motor (34) for causing opening of the door leaf (14) with respect to the door frame (12), and a controller (31) being configured for performing different functions (60) of the automatic door operator. The controller (31) is configured to detect (42) a movement of the door leaf (14), not caused by the motor (34), identify (44) a predefined movement matching the detected movement, determine (46), among the different functions, a function (61-A, 61-B) being associated with the predefined movement, and perform (48) the determined function.

The device comprises a main body, a fixing member affording fixing of a door leaf to the main body, a ball socket able to drive the main body under the effect of a motor, a roller able to move between (a) an active locking position in which the roller locks the ball socket with respect to the main body, in a closed position of the door leaf and (b) an inactive unlocking position in which a the roller allows displacement of the ball socket with respect to the main body. The device also includes a sleeve that allows a small movement of the fixing member with respect to the ball socket in a displacement direction from the closed position of the door leaf. The device further comprises a tooth that inhibits sleeve to immobilize the fixing member with respect to the ball socket, at least in translation in the displacement direction, when the roller is in the inactive position.

The subject matter of the invention are various methods, systems and devices and the ways of their installation/fitting/assembly of emergency opening of manholes (entry openings) or loading holes (door) in emergency situations, especially an emergency move/shift of movable components closing manholes (entry openings), exit openings, loading or unloading openings, from closed position into opened position, such as doors, manholes, hatches, gates, emergency exits, windows, window panes and other, especially in means of transport, construction furnishing devices and premises (buildings). The invention is connected with the use of pyrotechnic actuators which can be telescopic actuators, piston actuators or flexible ones, driven with propelling actuating agents which are in the form of gas generators, pressure of compressed gas or air, compressed air from a compressor or a material with shape memory.

A latch mechanism having a quick turn and release feature where the latch mechanism comprises a first body member having at least one actuation device. A second body member is coupled to the first body member and includes at least one aperture and pin receiving channel formed therein. A pin element is coupled to the second body member and includes a first pin portion and a second pin portion. The first pin portion and the second pin portion are respectively arranged to extend axially within the pin receiving channel of the second body member such that an upward rotation of the actuation device in a counterclockwise direction releasably disengages the pin element from a shaft of one or more hinges of the door assembly to allow an operator to exit an operator cab of the work vehicle.

A door drive assembly including: a drive arm including a first end configured to be rotatably coupled to the body and a second end configured to be rotatably coupled to the door. The door drive assembly also includes a drive mechanism coupled to the drive arm and configured to rotate the drive arm between an open position and a closed position. The door drive assembly also includes a control arm including a first end configured to be rotatably coupled to a vehicle body and a second end configured to be rotatably coupled to the door. The door drive assembly also includes a race configured to be disposed between the body and the first end of the control arm where the first end of control arm is configured to translate by a first distance along the race as the drive arm rotates between the open and closed positions.

A system for contactless operation of an aircraft lavatory door comprises a controller operatively connected to control an actuator for opening and closing a lavatory door. A gesture sensing system is operatively connected to the controller for sending gesture data to the controller indicative of a user gesturing for the actuator to actuate. A mmWave radar sensing system is operatively connected to the controller to indicate user presence. The controller includes machine readable instructions configured to verify gesture input from the gesture sensing system using input from the mmWave radar sensing system before controlling the actuator to open or close the lavatory door.

The disclosure relates to a pneumatic control system for a working cylinder, which pneumatic control system enables resistance-free manual motion of the device driven by the working cylinder in the event of a failure or switch-off of the compressed air supply and is independent of electrical supply. The problem is solved by means of a pneumatic control system having a double-acting working cylinder, the two chambers of which can be connected oppositely to a compressed air source and a compressed air outlet by means of a controllable supply device having two operating positions, an independently resetting 3/2-way valve switchable by means of a control pressure being arranged before each chamber in a connecting line to the supply device, which 3/2-way valves connect the chambers to bleeding outlets in a first switching position and to the supply device in a second switching position, and a parallel circuit of a check valve and a throttle point being arranged before each chamber, the check valves of which parallel circuits block in the backflow direction, wherein the two 3/2-way valves assume the first switching position in the idle position and can be switched by means of a common control line, which is connected to both connecting lines to the supply device downstream of the 3/2-way valves by means of a changeover valve, and the parallel circuits are arranged in the connecting lines downstream of the respective 3/2-way valves.

A retention mechanism for a pair of bi-parting doors of a transit vehicle includes a first track connected to a first door of the pair; a second track connected to a second door of the pair; a first retention assembly connected to the transit vehicle and configured to retain the first track in the closed position; a second retention assembly connected to the transit vehicle and configured to retain the second track in the closed position; a first engagement member connected to the second track, the first engagement member being configured to engage the first retention assembly to cause the first retention assembly to move to retain the first track in the closed position when the second track is in the closed position; and a second engagement member connected to the first track, the second engagement member being configured to engage the second retention assembly to cause the second retention assembly to move to retain the second track in the closed position when the first track is in the closed position.
