Abstract: An assembled subway station and a construction method thereof are provided. The assembled subway station includes a plurality of components combined in a ring shape, comprising a bottom plate component, two bottom corner components, two side wall components, a middle plate component, two top corner components, and a top plate component. Connection surfaces of each component are each provided with a concave-convex structure being matched with another concave-convex structure on a relevant connection surface of an adjacent component. Butt joint positions of two adjacent components are filled with sealing structures. The embedded grooves of two adjacent components are oppositely arranged, and connecting members for exerting opposite fastening forces on the two adjacent components are installed in the oppositely arranged embedded grooves.

Abstract: A vehicle door actuating device for a vehicle includes an actuator device disposed on one of a vehicle door and a door frame of the vehicle. A bumper is disposed on the other of the vehicle door and the door frame opposite the actuator device. A door sensor is disposed on the vehicle that measures door position and door movement. A controller receives data from the door sensor relating to the door position and door movement and activates the actuator device when the vehicle is in a parked position. The controller instructs the actuator device to repel the bumper to assist a user in opening the vehicle door and attract the bumper to assist a user in closing the vehicle door during closure.

Abstract: An apparatus for vehicle door deflection and movement control. The apparatus includes a primary electromagnetic device disposed generally in a vehicle door frame or generally in an area of a vehicle body adjacent the vehicle door frame, and a controller for activating the primary electromagnetic device to push or pull the vehicle door frame. The apparatus may further include a sensor for measuring vehicle door deflection during vehicle movement. The controller may activate the primary electromagnetic device based on deflection measurements by the sensor to pull the vehicle door frame to generally cancel the vehicle door deflection.

Abstract: This invention relates to an apparatus and a method for automatically removing radon gas trapped in a sump pit in a residential dwelling basement and dispensing it harmlessly into the atmosphere. This apparatus uses a Venturi nozzle in the discharge pipe from an existing sump pump system, sucks the radon gas in the sump pit when the sump pump pumps water and discharges it to atmosphere together with the discharged water through the existing discharge pipe of the sump pump system. The invention also relates to a radon inlet which floats with water surface to maximize the drawing of the radon gas. Two embodiments are present: One is suitable for underground water rich area and other is suitable for radon gas rich area to which a water storage and replenish tank is added.
