An emergency opening device for an aircraft door provided with an opening mechanism including an actuating device (2, 5) for the opening mechanism, which includes a tubular operating member (2); elastic compression device (5); an activation device (31) for the actuation device (2,5); the operating member (2) includes a first end element (10) and a second end element (11) which are freely translatable movable relative to each other along the movement axis (X).

Disclosed herein are system, method, and computer program product embodiments for detecting, alerting, and acting to prevent unattended vehicle deaths. An embodiment operates by receiving one or more signals from one or more presence sensors in a vehicle and analyzing the signals to detect the presence of a person or animal inside the vehicle. The system further receives one or more signals from one or more environment sensors on the vehicle and analyzes the signals to detect a dangerous environmental condition. If the system determines that both the presence of a person or animal has been detected inside the vehicle and a dangerous environmental condition has been detected, it activates one or more vehicle systems that mitigate the dangerous environmental condition and sends an alert to one or more predetermined recipients.

An apparatus comprising a baseplate configured to be coupled to an interior side of an inswing door adjacent a pivot edge of the door; a rotatable closing arm with a first end and a second end, the second end coupled to a motor, the motor configured to be engaged in response to receipt of a signal from a remote electronic device; and circuitry electrically coupled between a power supply and the motor, the circuitry configured to wirelessly send and receive information to and from the remote electronic device.

Described are passenger door assemblies including emergency passage feature assemblies. For example, a door assembly may include a latching block configurable to retain a latching spigot of a carriage assembly responsive to a first opening force. The door assembly may also be configurable to release the latching spigot to enable sliding movement of the latching block independent of the carriage assembly responsive to a second opening force.

Provided is a structure for operating a watertight door by use of buoyancy. The structure includes: a detention tank for storing rainwater flowing from a street inlet; a buoyant member which is installed in the detention tank; and a sensor installed in the detention tank, in which if the buoyant member raised by the buoyant of the rainwater collected in the detention tank comes into contact with the sensor, the watertight door is automatically operated. The watertight door structure manually operated at localized heavy rain is improved, and the watertight door is automatically operated if the water level reaches the predetermined level.

A swing door operator for moving at least one door leaf between a first and a second position includes a motor and a mechanical drive unit connected to and capable of moving the at least one door leaf from the first position to the second position, and a braking circuit connected to the motor. The braking circuit includes a diode circuit arranged to apply a voltage drop to the motor. The motor is adapted to act as a generator and is configured to generate a voltage when the drive unit moves the at least one door leaf, and to brake a movement of the at least one door leaf when the voltage generated by the motor is larger than the voltage drop applied by the diode circuit. The diode circuit includes at least three diodes connected in series.

A power window device includes a control unit configured to monitor a first potential at one end of a first switch circuit including a window closing switch and a second potential at one end of a second switch circuit including a window opening switch, and determine that submersion has occurred when the first or second potential is in a first or second submersion potential range. During a normal time, the control unit outputs a window closing command signal when the first potential is a potential at a time of the window closing switch being operated, and outputs a window opening command signal when the second potential is a potential at a time of the window opening switch being operated. At a time of submersion, the control unit does not output the window closing command signal, and outputs the window opening command signal.

A power window device includes a control unit configured to monitor a first potential at one end of a first circuit including first and second switches turned on by manual opening and closing operations for a window, respectively, and a second potential at one end of a second circuit including a third switch turned on by an automatic opening or closing operation. The control unit is configured to output a manual window opening signal to a motor drive unit when the first potential is a potential at a time of the first switch being turned on; output a manual window closing signal when the first potential is a potential at a time of the second switch being turned on; and output an automatic window opening or closing signal when the second potential is a potential at a time of the third switch being turned on.

The hold-open arrester arrangement has a hold-open arrester arrangement having a hold-open function to hold a door open. The arrangement has also an electric release arrangement. The release arrangement is arranged to release the hold-open function in a fire alarm situation. The hold-open arrester arrangement comprises a sliding block and an arrester unit. The sliding block is connectable with a slide rail in a sliding manner and also pivotable connectable to an arm of a door closer. The arrester unit is connectable to the slide rail and has a body, said electric release arrangement, and said hold-open function with the sliding block.
