Abstract: The present invention relates to a water treatment system for removing at least some of ionic materials included in source water to provide soft water comprising less ionic materials than the source water to a demand source. The water treatment system may comprise: a filter module provided so as to remove at least some of ionic materials included in source water by means of an electrical force to discharge soft water; a supply channel provided so as to supply the source water to the filter module; a discharge channel provided so as to guide the soft water discharged from the filter module to a demand source; a circulation channel branched from the supply channel; a reclaim channel branched from the discharge channel; a connection channel branched from the reclaim channel and connected to the circulation channel; and a descaling part connected to the connection channel and provided so as to provide a descaling material for removing scale to the inside of the connection channel.

Abstract: A vehicular aerodynamic performance improvement apparatus is provided. The apparatus includes an air current regulator to extend out of and retract into a rear section of a vehicle, and regulate air current that flows along a roof of the vehicle toward an opposite direction from a forward traveling direction of the vehicle, a lamp provided on the air current regulator, and a driver to generate a drive force to operate the air current regulator.

Abstract: A variable spoiler apparatus including a spoiler unit movably provided in a rear section of a vehicle and configured to extend or be tilted toward a direction opposite from a forward traveling direction of the vehicle according to a traveling mode of the vehicle and a rear lamp provided in the spoiler unit and configured to emit light toward the direction opposite from the forward traveling direction.

Abstract: An image sensor according to an example embodiment of includes a first pixel and a second pixel in a first row. The first pixel includes a first photoelectric conversion element at a first depth in a semiconductor substrate and the first photoelectric conversion element is configured to convert a first visible light spectrum into a first photo charge, and the second pixel includes a second photoelectric conversion element at a second depth from the first depth in the semiconductor substrate, the second photoelectric conversion element is at least partially overlapped by the first photoelectric conversion element in a vertical direction, and the second photoelectric conversion element is configured to convert a second visible light spectrum into a second photo charge.
