Abstract: A window includes: a window frame having an opening defined therein through which an outdoor space and an indoor space communicate with each other; a pair of sashes slidably disposed in the window frame and that slide along an opening direction and a closing direction opposite to the opening direction; variable transmittance windowpanes configured to be fitted in the sashes to open and close the opening together with the sashes depending on sliding of the sashes; the variable transmittance windowpanes having a transmittance variable by electrical connection; first conductive members disposed on the sashes and electrically connected with the variable transmittance windowpanes to supply electric power to the variable transmittance windowpanes; and a second conductive member electrically connected with the first conductive members to supply the electric power to the first conductive members from outside the window frame.

Abstract: An auto white balance method is disclosed. The auto white balance method includes receiving image data to divide the image data into a plurality of partition cells, calculating an estimation value of a skin tone included in the image data, and selecting outliers for detection of a white point of the image data, based on at least some of the plurality of partition cells and the estimation value.

Abstract: The present disclosure relates to an information display device using a variable transmissivity glass. The information display device includes a controller that divides an entire region of the variable transmissivity glass into a first region and a second region, and adjusts transmissivities of the first region and the second region to be opposite to each other to display information in the first region.

Abstract: Disclosed are a polarizing substrate and a variable transmissivity device including the polarizing substrate. The variable transmissivity device includes a first polarizing substrate and a second polarizing substrate, each of which includes a transparent base layer and a polarizing layer formed on at least one surface of the base layer, for example, formed by a coating method, a liquid crystal layer disposed between the first polarizing substrate and the second polarizing substrate, a first alignment layer and a first transparent electrode stacked on a first surface of the liquid crystal layer in a direction in which the first polarizing substrate is positioned, and a second alignment layer and a second transparent electrode stacked on a second surface of the liquid crystal layer opposite to the first surface of the liquid crystal layer in a direction in which the second polarizing substrate is positioned.

Abstract: A reaction hydraulic turbine used for converting the energy of a flowing stream into mechanical energy of a rotating shaft is disclosed. In the turbine, the blades have a specifically-designed configuration suitable for not only reducing the hydraulic resistance but also for concentrating the energy of the flowing stream onto the blades. The internal surface of each blade has a half-circular curved section, while the external surface has a streamline section, which is smoothly put into or come out of water thus being almost completely free from hydraulic resistance. At the lowermost portion of the turbine, the energy of the flowing stream is effectively concentrated onto the curved internal surface of each blade.
