Abstract: A method for securing a plurality of compute nodes includes authenticating a hardware architecture of each of a plurality of components of the compute nodes. The method also includes authenticating a firmware of each of the plurality of components. Further, the method includes generating an authentication database comprising a plurality of authentication descriptions that are based on the authenticated hardware architecture and the authenticated firmware. Additionally, a policy for securing a specified subset of the plurality of compute nodes is implemented by using the authentication database.

Abstract: An inorganic-organic hybrid coating applied to a polymer and method for forming same to provide improved hydrophilicity and lubricity to the surface of the polymer. The hydrophilic coating is on the order of one micron thick, as is formed by activating the surface of the polymer, reacting the activated surface of the polymer with a Lewis acid metallic composition, and then quenching the coating in salt solution having a pH>7.2 at a temperature above the glass transition temperature (Tg) of the polymer.

Abstract: An implantable contact lens having a central hole with angled walls optimized to minimize light scattering is described. The central hole provides fluid flow from the posterior to the anterior chamber of the eye, and its shape and size of designed to reduce glare and halos resulting from light scattered by the walls of the hole. The design parameters of the hole are dependent on the refractive index of the material in which the central hole is formed.

Abstract: A new type of multi-focal lens that has a free-form progressive multifocal front surface consisting of a 16th order polynomial superimposed on a standard conic base surface is described. The center region of the lens is optimized for distance vision, while simultaneously optimizing the rest of the lens for near vision. The resulting free-form even asphere polynomial surface is smooth, unlike present day diffractive multifocal designs. Additionally, this lens design is suitable for both refractive and cataract surgeries.

Abstract: An optimized aspheric lens has improved optics when implanted into a patient having a curved retina. Light entering the optimized aspheric lens on-axis or at an angle to the optical axis is properly focused by the lens, reducing aberrations and producing a much smaller spot size of light on the retina. A method of selecting the optimized values for variables of the lens design, such as base radii of the front and back surface of the lens, conic constants of the front and back surfaces, and/or center thickness of the lens, among other possible parameters is provided. The method includes calculating changes in a merit function while changing the various values for the variables and selecting an optimized merit function.

Abstract: A system and method of processing an item at least partially formed of a hydrophilic material to reduce or increase the item's protein affinity. In one example, the system and method prevent or greatly reduce the formation of insoluble ionic materials in or on the item during processing, thereby reducing its affinity for binding with pertinacious materials. An example application involves reducing the protein affinity of an ocular item such as an intra ocular lens or a contact lens, thereby reducing the potential for in-eye or on-eye ossification of the item.

Abstract: A process for forming an intraocular lens with haptics having high fracture toughness mixing solid particles with an uncured polymer matrix and introducing the uncured mixture into a mold. Ultrasonic energy is then applied to the mold until the uncured mixture begins to solidify. Sufficient heat is then applied to the polymer mixture to completely cure the polymer. The cured polymer which will form the haptics, is then removed from the mold and a hole for forming the optic is formed in the cured polymer. An uncured polymer matrix suitable for use, when cured, as an optic, is then introduced into the hole and cured. An intraocular lens is then machined from the resulting cured composition.

Abstract: In a method of producing an intraocular lens having a substantially clear optic and at least one filamentous haptic having high fracture toughness, solid particles are mixed into an uncured polymer, and the mixture is inserted into a mold. Ultrasonic energy is applied to the mold until the mixture solidifies. Heat is applied to complete the curing process. Ultrasonic energy is also preferably applied to the particles and uncured polymer mixture to improve dispersion of the particles therein.

Abstract: An intraocular lens comprises a substantially clear optic and at least one filamentous haptic having high fracture toughness. The haptic is formed of a polymer composition comprising low concentrations of solid particles uniformly dispersed throughout a polymer matrix.

Abstract: A method of producing a nonwoven fabric from a web of fibers, said fibers being substantially nonreactive to microwave energy, comprising applying a microwave reactive material to fibers in said web, subjecting the web to microwave energy at a temperature and for a time to heat said microwave reactive material sufficiently to cause bonding at at least some of the fiber intersections in said web thereby producing a nonwoven web. The resulting nonwoven fabric has a number of uses and is especially suitable as primary carpet backing.
