Abstract: The present invention discloses a method to prepare the polymer-clay nanocomposite latex. At first, a clay and a water-soluble initiator are mixed in water to form an intermediate solution, in which the initiator is absorbed or intercalated into the clay. Then, at least one monomer from vinyl ester, acrylic and acrylamide derivatives is added into the intermediate solution for soap-free emulsion polymerization, which may also be added with some other monomers such as acrylic acid, maleic anhydride, vinyl chloride, acrylonitrile ethylene, et al. for copolymerization. During soap-free emulsion polymerization, the radicals from the dissociated initiators will react with the monomers to form the monomer radicals, which tend to diffuse into the interlayer region of clays for further polymerization and eventually exfoliate the clays. The prepared exfoliated polymer-clay nanocomposite latex can be cast into a vapor-impermeable film so that it can be used as a sealing material or coating.

Abstract: A method is disclosed to determine whether a product, a component or a system (hereafter, we use “group” to simplify such wide scope though “product” is used for clarity in some places; hence, the first is refereed to as “group 1”) in reliability life testing has longer lifetime than the other (i.e., “group 2”). This method is free from the assumption on the form of distributions (i.e., it is a nonparametric method from statistics standpoint) and the proposed data analysis approach can be applied to all kinds of data and distributions. This method provides a more accurate solution than parametric methods, whose results may have certain errors from the goodness-of-fit at distribution fitting & parameter estimations. After the pre-check on bimodal, early failures, and the failure mechanisms, our invention employs numerical solutions with good accuracy by nonparametric approaches; the data under consideration can be censored, interval or bimodal, not limited to simple case of the complete type.

Abstract: The present invention provides a driving method suitable for a plasma display. The plasma display includes multiple scan electrodes, multiple sustain electrodes and multiple address electrodes, for example. Successive frames are adapted to be displayed in repeating reset periods, address periods and sustain periods by applying driving signals to the scan electrodes, sustain electrodes and address electrodes. The driving method is characterized in that before inputting driving signals or when interrupting driving signals, a wall-charge removing signal is applied to the scan electrodes to remove/reduce the residual wall charges around the scan electrodes and the sustain electrodes. As a result, the possibility of the plasma display generating erroneously discharging with strong light at the restarting state can be effectively reduced.
