Abstract: An overlay measurement device measures an error between a first overlay mark and a second overlay mark respectively formed on different layers formed on a wafer. The device is configured to detect a height of the first overlay mark based on a change in the signal of the first detector according to a change in the relative position of the objective lens with respect to the wafer in the optical axis direction and detect a height of the second overlay mark based on a change in the signal of the second detector according to a change in the relative position of the objective lens with respect to the wafer in the optical axis direction.

Abstract: A fire spreading prevention system for a vehicle can prevent a fire breaking out in a battery mounted in the vehicle from spreading throughout the vehicle. The fire spreading prevention system includes a battery state detector that detects battery state information for sensing a battery fire in the vehicle; a controller that outputs a control signal for removing a battery upon determining that the battery fire breaks out; and a battery removal apparatus installed in the vehicle to fix the battery to a vehicle body, and configured to release the battery from the vehicle body and simultaneously to remove the battery from the vehicle in response to the control signal from the controller. When a fire is sensed, the fire spreading prevention system removes the battery from the vehicle and separates and discharges the battery to outside of the vehicle, thereby preventing the fire from spreading throughout the vehicle.

Abstract: A fire suppression apparatus for a vehicle includes: a docking unit disposed on an exterior panel of a vehicle body, the exterior panel configured to cover an interior space of the vehicle wherein the docking unit comprises a hole through which a fire-fighting hose or a spray nozzle, which is connected to the fire-fighting hose, for supply of fire-fighting water pass to be coupled to the docket unit; a supply pipe having a first end connected to the docking unit; and a nozzle assembly arranged in the interior space in the vehicle and connected to a second end of the supply pipe, the nozzle assembly being configured to spray the fire-fighting water, which is supplied through the supply pipe from the fire-fighting hose or the spray nozzle, in order to respond to the outbreak of a fire in the interior space of the vehicle.

Abstract: A fire extinguishing system for a vehicle includes a fire detection device outputting a fire detection signal in response to detecting a fire and is installed in a predetermined space of the vehicle. A controller outputs a control signal for spraying fire extinguishing agent when the fire detection signal is received from the fire detection device. An air tank stores compressed air and a fire extinguishing agent cylinder is connected to the air tank through an air hose, is filled with the fire extinguishing agent, and is operated to discharge the fire extinguishing agent by the compressed air, supplied from the air tank through the air hose, by the control signal. A spray nozzle assembly is connected to the fire extinguishing agent cylinder through a fire extinguishing agent hose and sprays the fire extinguishing agent being supplied, from the fire extinguishing agent cylinder, through the fire extinguishing agent hose.

Abstract: A fire extinguishing system for a tire of a vehicle is capable of effectively responding to a fire in all tire areas of the vehicle, and of spraying fire extinguishing agent selectively only for the tire having the fire, thereby performing effective fire extinguishing.

Abstract: A fire extinguishing system is provided for a tire of a vehicle. The fire extinguishing system includes fire extinguishing injectors filled with fire extinguishing chemicals and installed in the vehicle to be able to inject the fire extinguishing chemical to the tire. A fire detection line is installed to connect between the fire extinguishing injectors. Each of the fire extinguishing injectors is configured to inject the fire extinguishing chemical when a fire of the tire is detected through the fire detection line.
