A study of the refractivity bias in occultation retrievals using end-to-end simulations

Direct Methanol Fuel Cells in portable applications are expected to provide substantially higher energy density and longer operating times over advanced batteries. The time threshold of advantage of using a fuel cell instead of a battery is almost independent of the power level, and is determined by the power density of the fuel cell and its operating efficiency.

84‐2: Invited Paper: High Refractive Index Light Extraction for OLED Lighting

In this work, we will present the requirements for light extraction in OLED lighting, review Pixelligent's approach to light extraction, and present results from OLED lighting panels made at OLEDWorks incorporating our technology. These results have shown an improvement of greater than 2.6X in efficacy when compared to devices with no light extraction.
