  • Patent number: 9513591
    Abstract: An improved overcoat layer for an organic photoconductor drum of an electrophotographic image forming device is provided. The overcoat layer is prepared from a curable composition including a triphenylamine charge transport containing two ethyl acrylate functional groups and a urethane resin containing six radical polymerizable functional groups. The amount of the triphenylamine charge transport containing two ethyl acrylate functional groups in the curable composition is about 20 to about 80 percent by weight. The amount of the urethane resin containing six radical polymerizable functional groups in the curable composition is about 20 to about 80 percent by weight. This overcoat layer improves wear resistance of the organic photoconductor drum without negatively altering the electrophotographic properties, thus protecting the organic photoconductor drum from damage and ultimately providing a photoconductor with a longer useful life when compared to other organic photoconductors commercially available.

  • Patent number: 8849631
    Abstract: A method of telephone call management in process of service development that allows a user to model and create telephone call management schemes independent of telecommunications protocols and network layer details. The method of the invention operates by creating an abstract model of a telephone call life-cycle that is converted, using a set of communication threads, into executable code. Models in accordance with the method of the invention are constructed using an Integrated Development Environment (IDE) for creating and developing telecom services that embodies the Telecom Service Domain Specific Language (TS-DSL) which is implemented as a Unified Modeling Language (UML) extension for the telecom domain. By this method, individuals without specialized knowledge of telecom related software programming and protocols can successfully design and implement telecom services that manages calls.
