  • Patent number: 9495022
    Abstract: A method and apparatus for detecting by a digitizer an application of an electronic pen on or within a predetermined distance from a screen of an electronic device, and includes compensating coordinates of an electronic pen relative to screen. At least one magnetic field is detected that is produced by the electronic pen and that has a different central axis each other The digitizer determines whether the electronic pen is inclined based on a number of detected magnetic fields. A determination is made whether to apply a compensation value for compensating coordinates of the electronic pen based on determining inclination of the electronic pen. The present invention advantageously permits exact recognition of coordinates of the electronic pen whether then pen is inclined or not by performing the coordinate compensation taking into account the inclination of the electronic pen and the inclined direction.

  • Publication number: 20160315277
    Abstract: Disclosed is a moisture barrier film for an organic-inorganic hybrid photovoltaic cell which includes an ionic polymer. Also disclosed is an organic-inorganic hybrid photovoltaic cell including the moisture barrier film. The photovoltaic cell has a structure in which the moisture barrier film including an ionic polymer is formed on an absorber layer including an organic-inorganic hybrid perovskite compound. Due to this structure, the moisture barrier film effectively protects the organic-inorganic hybrid perovskite absorber layer, which is very susceptible to moisture, and other constituent layers, from moisture from the external environment so that excellent characteristics of the photovoltaic cell can be maintained for a long time. In other words, the moisture barrier film including an ionic polymer is interposed between the absorber layer and a hole transport layer or between the hole transport layer and a second electrode to enhance the physical and chemical binding therebetween.

  • Patent number: 9469804
    Abstract: A foaming composition with wettability-modifying and corrosion inhibitory properties is used to control the channeling of fluids in naturally fractured carbonate reservoirs, favorably alter the rock wettability in crude oil enhanced recovery processes and control uniform corrosion problems occurring in production rigs under high temperature and ultra-high salinity conditions by the synergistic effect resulting from the supramolecular interaction of alkyl amido propyl hydroxysultaines or alkyl hydroxysultaines with sodium alkyl hydroxysulfonates and sodium alkenyl sulfonates having the formula (1). The foaming compositions with wettability-modifying and corrosion inhibitory properties are tolerant to high concentrations of divalent ions such as calcium, magnesium, strontium and barium and are suitable for use in the reservoir, seawater and/or congenital water characteristic of the reservoir for transporting the crude oil from the reservoir.

  • Publication number: 20150371787
    Abstract: Disclosed is a method for adsorbing a dye for a dye-sensitized solar cell. The method includes: coating a paste including metal oxide nanoparticles on the upper surface of a titanium oxide thin film and calcining the coated paste to form a porous film; adding an additive to a sensitizing dye solution to promote the adsorption of the dye; and dipping the porous film in the sensitizing dye solution to adsorb the sensitizing dye onto the surface of the porous film. The sensitizing dye solution is a dispersion of the sensitizing dye in an organic solvent. Also disclosed are a working electrode prepared using the sensitizing dye solution and a dye-sensitized solar cell including the working electrode. The addition of the additive shortens the time of dye adsorption. Despite the shortened adsorption time, the dye does not undergo desorption in the long term as well as in the short term, ensuring long-term stability of the solar cell.
