  • Publication number: 20150322280
    Abstract: A scratch resistant film formed by altering a surface energy of at least a portion of a substrate and disposing a first layer of coating on the substrate. The first layer of coating comprises a plurality of functionalized monomers and a solvent. The substrate then may enter a transition zone to wet the first layer of coating, wherein wetting the first layer of coating comprises disposing the substrate in a transition zone subsequent to disposing the first layer of coating. The first layer of coating is cured, and a second layer of coating is disposed on the first layer of coating, wherein the second layer of coating has a lower surface energy than the first layer of coating. The substrate may then enter a transition zone and be subsequently cured. A scratch-resistant film is formed; this film may be transparent, translucent, opaque, or combinations thereof.

  • Publication number: 20140370848
    Abstract: A data exchange system for facilitating the purchase of cellular or wireless phone minutes and/or blocks of cellular time is provided. Potential cellular time and data buyers and sellers may access the exchange system via the internet and submit offers and or pricing requests to such a system. In response to the request, a server retrieves stored data from the seller's database, and allows for the potential buyer to view the cellular data or minutes for sale. The buyer and the seller exchange the related data and the minutes. The exchange system executes the transfer of the cellular minute and the data, via financial transactions between the buyers and the sellers, and then updates corresponding accounts of the buyers and sellers in conjunction with an appropriate cellular service network provider.
