Acrylic, high refractive index ophthalmic device materials comprising an aryl acrylic monomer, a first stage polymerization initiator and a second stage cross-linking agent are prepared in a two-stage method. The control device is enabled to receive external data and to apply the data to the nonvolatile memory, and the nonvolatile memory is enabled to operate a program operation including storing the received data to the buffer memory and storing the data held in the buffer memory to ones of nonvolatile memory cells. The middleware machine environment also comprises one or more host servers, each of which is associated with one or more virtual machines that can process the data packets. In another embodiment, the amphiphilic heparin derivative is dissolved in an aqueous solvent, a surfactant is mixed with the aqueous solvent and nanoparticles of the amphiphilic heparin derivative are disrupted, resulting in nanoparticles having surfactant molecules associated with the hydrophobic agent on the outside of the nanoparticles. After being processed by the OCR procedure, a summarizing ranking is calculated for each potential address block found.
