An organic light emitting device comprises an outcoupling layer having relatively high aspect ratio nanowires imbedded within an optically thick transparent high optical index film. The weight body includes a U-shaped transverse cross-section and a groove for mounting the clip therein. In addition the estimation includes detecting a plurality of predetermined pilot signals and determining a phase correction factor on the basis of the detected pilot signals, with at least one multiplication operation carried out solely by means of shift and adding operations. In another embodiment the card includes a programmable magnetic strip, a plurality of features stored in memory means mounted on the card, a plurality of buttons or contacts, and means for programming the magnetic strip with a different card feature. Certain methods include imposing a de-stabilizing force directly to the foam or to the molten mass and foam, where the de-stabilizing force may be a vibratory force, an acoustic wave force, a particulate-based force, or a non-particulate-based mechanical force.
