Abstract: A display device is provided. The display device includes a display panel, a backlight unit, and a luminance comparison unit. The backlight unit is configured to supply light to the display panel. The luminance comparison unit is configured to compare a measured luminance of the display panel with a reference luminance range. The backlight unit includes a light source unit, a DC-DC converter, and a driving current controller. The DC-DC converter is configured to supply a driving voltage to the light source unit, and the driving current controller is configured to control a driving current flowing to the light source unit based on the comparison result of the luminance comparison unit.

Abstract: The present invention relates to a technology of reducing nitrogen oxide (NOx) which is harmful discharge gas discharged from an internal combustion engine or a combustor, and to an exhaust gas purification system which inputs solid ammonium salt such as ammonium carbamate or ammonium carbonate into a reactor, thermally decomposes and converts the solid ammonium salt into the ammonia by using engine cooling water, exhaust gas, or an electric heater, which are installed in the reactor, and reduces the nitrogen oxide included in the exhaust pipe on a selective catalytic reduction into nitrogen by injecting the ammonia by using a pressure regulator and a dosing valve.

Abstract: Provided is a multi-functional vehicle including: a sampling unit through an external air flows in, the sampling unit having a particle sampling inlet tube and a gas sampling inlet tube; a flow distribution unit for supplying the air flowing in through the particle sampling inlet tube to a particle measuring device; a manifold for supplying the air flowing in through the gas sampling inlet tube to a gas measuring device; a particle measuring device for measuring particles in the air supplied from the flow distribution unit; a gas measuring device for measuring gas in the air supplied from the manifold; an animal exposure chamber system for receiving the air from at least one of the flow distribution unit and the manifold and performing an animal exposure experiment; and a data management unit for storing and monitoring air pollution data measured by the particle measuring device and the gas measuring device.

Abstract: Disclosed is a laser rangefinder and method thereof. By using characteristics that noise has non-correlation and signals have correlation, laser beams are output to a target to find a range to the target with iteration rates of thousands of times per second, signals for each range-finding are binary-quantized using a sampling frequency corresponding to a range-finding resolving power, and data are accumulated. After this, the accumulated data are processed in a statistical manner to detect a target signal and produce a target range based on the target signal. According to the present invention, the rangefinder for outputting low-power laser beams, using the laser beams reflected from the target, and detecting a range to the target, easily and accurately detects target signals in the noise.
