  • Publication number: 20140040463
    Abstract: A system and computer-implemented method for determining an estimated number of unique visitors to a network location from a geographical area. A non-linear approximation is utilized to determine the estimated number of unique visitors to the network location. The non-linear approximation is based on at least the estimated number of users within the geographical area, the estimated number of unique user identifiers within the geographical area, and the number of unique user identifiers from the geographical area that are observed at the network location.

  • Patent number: 8636833
    Abstract: A method for filtering particles from water mist laden air involves passing the air through a medium that has a nanoweb layer in fluid contact with a hydrophobic nonwoven web. The hydrophobic web can be made of an intrinsically hydrophobic material, or can be coated with a hydrophobic coating. The medium does not undergo the large pressure drops normally associated with filtration of water mists and retains its efficiency well.

  • Publication number: 20130293441
    Abstract: The disclosure discloses a method and device for realizing Specific Absorption Rate (SAR) control, in both of which phase shifters can be provided on a metal ground edge of a wireless terminal, and an induced current of the metal ground edge can be altered by applying the phase shifters, so as to reduce an antenna near field radiation characteristic of an SAR. The method and device of the disclosure can alter current phase and amplitude distribution of the metal ground without affecting the reception and transmission performance of the terminal, so as to reduce a local SAR peak value and lessen the harm of radiation to human bodies. Furthermore, the disclosure does not require any major change in a structure, circuit, and, antenna of a designed model, and can save space. The disclosure bears great flexibility and adaptability in an application, thereby realizing the objective of miniaturized design of the wireless terminal.

  • Publication number: 20130224538
    Abstract: The present invention provides a non-aqueous redox flow battery comprising a negative electrode immersed in a non-aqueous liquid negative electrolyte, a positive electrode immersed in a non-aqueous liquid positive electrolyte, and a cation-permeable separator (e.g., a porous membrane, film, sheet, or panel) between the negative electrolyte from the positive electrolyte. During charging and discharging, the electrolytes are circulated over their respective electrodes. The electrolytes each comprise an electrolyte salt (e.g., a lithium or sodium salt), a transition-metal free redox reactant, and optionally an electrochemically stable organic solvent. Each redox reactant is selected from an organic compound comprising a conjugated unsaturated moiety, a boron cluster compound, and a combination thereof. The organic redox reactant of the positive electrolyte is selected to have a higher redox potential than the redox reactant of the negative electrolyte.

  • Publication number: 20130118780
    Abstract: The disclosure discloses a wireless terminal with a reduced Specific Absorption Rate (SAR) peak. The wireless terminal comprises a Printed Circuit Board (PCB), wherein a fractal gap is formed at an edge of a metal ground on the PCB to disturb distribution of induced current at the edge of the metal ground. The disclosure also discloses a method for reducing an SAR peak. On the premise of the non-influence on the communication quality of the wireless terminal, the SAR and the production cost can be reduced and the structure space of wireless terminal can be saved by using the wireless terminal and the method.

  • Patent number: 8440479
    Abstract: A method for sealing an organic light emitting diode (OLED) device is disclosed wherein the OLED device comprises a color filter. A color filter is deposited on a first glass plate or substrate and a glass-based frit is then deposited in a loop around the color filter, The deposited fit loop is then heated by electromagnetic energy to evaporate organic constituents and to sinter the fit in a pre-sintering step. An OLED device may then be assembled by positioning a second glass plate comprising an organic light emitting material deposited thereon in overlying registration with the first glass plate, with the color filer and the organic light emitting material positioned between the plates. The fit is then heated with a laser to form a hermetic seal between the first and second glass plates.

  • Publication number: 20120218640
    Abstract: A glass article having a low level of grainy appearance that can appear to have a shift in the pattern of the grains with changing viewing angle of a display, or “sparkle.” The glass article—which, in some embodiments, is a transparent glass sheet—has small-angle-scattering properties and/or distinctness-of-reflected-image (DOI), leading to improved viewability in display applications, especially under high ambient lighting conditions. In some embodiments, the antiglare surface of the glass sheet is an etched surface, with no foreign coating present on the antiglare surface.

  • Patent number: 8244418
    Abstract: A weather awareness and warning system (“WAWS”) provides aircraft position data and weather data input to a weather alert (“WA”) processor from a navigation system and a datalink system. The weather data contains three-dimensional delineations of a defined weather area. The WA processor determines an aircraft alert position and a weather alert zone; if the aircraft alert position falls within or penetrates the weather alert zone, the WA processor generates an alert signal and provides a weather alert signal to an alerting system comprising of visual alert(s) displayed on a display unit such as an HDD unit or a HUD unit, or an aural alert sounded by an aural alert unit. The aircraft alert position and weather alert zone could be determined by the WA processor by executing an algorithm(s) embedded in software containing the disclosed embodiments and methods.
