In a vehicle emergency evacuation device which stops a running vehicle automatically or keeps a stop state of a stopped vehicle in a driver's emergency, a stop keeping process is executed to keep the stop state without conducting an intention confirmation process of the execution start of an emergency evacuation process when the emergency evacuation process is required, e.g. when an abnormality or a deterioration in the driver's condition arises or when the driver requests the emergency evacuation process, under a condition that the vehicle has stopped before a signal, a road crossing or a railroad crossing, thereby ensuring the safety of the vehicle. Moreover, there are provided a structure in which the stop site of the vehicle in the execution of automatic vehicle stop control is determined depending upon whether the running road is a driveway, a highway, or a normal road; and a structure that judges whether or not to permit an override to the emergency evacuation process after the execution start of the emergency evacuation process based on a passenger's motion.

In a vehicle emergency evacuation device executing an automatic vehicle stop control based on a command of the driver through a switch or a command input device in a driver's emergency, there is provided a switch or a command input device which is easy to operate when a driver's body condition is abnormal or deteriorates but does not erroneously receive a command input when the driver's body condition is normal. The inventive emergency evacuation device comprises a driver's condition monitoring portions, such as a driver camera; a driver's command input portion that has a receptor put on a position accessible for the driver and receiving a command input indicating a driver's intention, and outputs a command of an execution start of an automatic vehicle stop control based on the command input; and an automatic vehicle stop control portion executes the automatic vehicle stop control in response to the command from a driver's command input portion, where, only when an abnormality in a driver's body condition is judged based on the information acquired by the driver's condition monitoring portion, such as a driver's image acquired with the driver camera, the command input is acceptable to the receptor.

An economical emergency evacuation mattress for persons in areas with limited access, such as subways and high-rises, provides a warm and secure cocoon for the patient, allows easy transport over any type of surface (e.g., up and down stairs), provides proper support for all of the patient's body, allows the patient to feel a high degree of comfort in what is otherwise a very stressful situation, and provides securing means (e.g., straps) to firmly hold the patient in place during transit.

From ancient history until now, man has constructed high-rise buildings of various kinds. They include monuments, castles, churches, office buildings, hotels, hospitals and residences. No matter how sophisticated construction techniques and technology have become, there is no system to transport people and equipment to or from selected locations between the ground level and roof of a high-rise; quickly, economically, consistently and safely outside the structure. Reed's High-Rise Emergency Rescue Egress System is such a system. This system solves the myriad problems which have existed for centuries relating to a need for external, vertical high-rise emergency evacuation and does so with substantial cost-efficiencies. Reed's High-Rise Emergency Rescue Egress System is comprised of varied electronic and mechanical components operating in unison. The three major pieces to the high-rise system are; a vehicle, a gondola and a roof-mount cantilever: The vehicle is a self-powered ground vehicle containing a gondola, stabilizing steel cables, drums, television screens, video cameras, communications, and remote control equipment. Once linked to a cantilever it provides power for lifting the gondola, equipment and personnel to monitor all activities below, beside or above the fire area. The self-powered cantilever is, remotely or manually, positioned on the roof of a high-rise building to a desired area of operation. The cantilever extends its connection arm over the edge of a high-rise building and lower cables to the ground rescue vehicle to make necessary connections with the gondola for traveling up and down the walls of a high-rise building. The cantilever roof-mount system is portable and contains steel cables, electric/hydraulic wenches, radio receivers, transmitters and video communication. The gondola, an enclosed cabin, is positioned on the rear, body portion, of the high-rise rescue vehicle. Once the gondola is linked to the vehicle and cantilever arm it becomes an exterior enclosed transporter in a matter of minutes. Reed's High-Rise Emergency Rescue Egress gondola will carry up to eight fully equipped firemen and can scale the wall of a burning building in minutes. The gondola carries firefighters and equipment below, beside or above the fire, while at the same time providing trapped building occupants a safe means of escape. A modified version of the gondola is used for high-rise building construction and maintenance.

A seating arrangement in an aircraft passenger cabin includes rows of seats, one behind another at a prescribed seat pitch. A wider transverse aisle is formed between successive seat rows at a normal exit or an emergency exit. At least one seat row bordering on and facing the transverse aisle is equipped with foldable passenger seats that each have an upwardly tiltable seat bottom and armrests. By tilting up the seat bottom and the armrests, an enlarged width of the transverse aisle is provided in the event of an emergency evacuation. In normal operation, the prescribed transverse aisle width does not need to be maintained, i.e. can be reduced, so the seat bottom and armrests are tilted down into the normal-use position for a passenger to be seated on the seat. Thereby the seat pitch of this seat row can be reduced and the total seating capacity can be increased.

The invention discloses a method and a system for evaluating road emergency evacuation capacity and a method and a system for grading the road emergency evacuation capacity. The method for evaluating includes steps of acquiring a plurality of evaluation indexes used for evaluating road emergency traffic states, acquiring a time dimension principal component and a space dimension principal component by aid of a principal analysis method according to the evaluation indexes of road emergency traffic states, and then determining integrated index of road emergency evacuation capacity.

An emergency evacuation slide system includes a control valve having a normally-open vent that closes after a predetermined period of time calculated to vent excess inflation gas produced by the gas generator. In operation, in the event of an aircraft emergency exit door being opened in the “armed” condition, the primary valve member of the control valve is opened allowing inflation gas to flow into the valve chamber. A portion of the gas entering the chamber is vented through the normally-open vent. After a predetermined period of time calculated to be sufficient to vent the excess inflation gas, the normally-open valve is closed to divert 100% of the remaining inflation gas into the evacuation slide.
