  • Patent number: 6275937
    Abstract: Method, system and computer program product for collaboratively processing a data object in a client-server hierarchy based on meta-information associated with the object. Processing results are indicated by the server that performed the processing as updates to the meta-information associated with the data object. The PICS protocol may be used to communicate the meta-information. Digital signing and authentication of the object and associated meta-information are also described. Further, servers can determine processing by considering various factors, e.g., their current load condition; if the object is to be multicast; if the object can be cached; and/or if the specified cost and time constraints can be met. The overall processing applied to data objects can be divided between servers based on object types, steps, functions, software packages or versions/releases. Other aspects of the invention are also described.

  • Patent number: 5198867
    Abstract: Adaptions of lensmeter optical trains are disclosed for enabling the measurement of contact lenses without the interference of spherical aberration from the highly meniscus lens formats of contact lenses. A generic system of measurement of the contact lenses when off of the eye is introduced by having light incident to or passing from the suspect contact lenses at an approximate aplanatic condition of the contact lens. The approximate aplanatic condition is determined by taking the average power of the posterior and anterior surfaces of the contact lenses for the general population--approximately 8 mm, assuming an index of refraction of approximately 1.5--calculating the aplanatic condition for such a "surface," and having light incident on the lenses for the interrogation of the lenses approximate the aplanatic condition.

  • Patent number: 5037677
    Abstract: Interlaminar grafting of coatings, particularly grafting of a lubricious outer coating upon an anchor coating supported upon glass or plastic, for example, to provide anti-fogging or lubricating characteristics. The method is characterized by its ability to anchor permanently the highly lubricious coating to the glass or plastic.

  • Patent number: 5023114
    Abstract: Plastics, particularly a method of hydrophilic coating of plastics, for example, a contact lens, with a lubricating and visually acute mucopolysaccharide film which is immobilized upon the surface of the plastic for the lifetime of the plastic. A preferred method includes first coating the plastic with an aqueous solution of a mucopolysaccharide, drying by applying a water-miscible solvent, then crosslinking and permanently immobilizing the first coating upon the plastic by applying a solution of catalyzed organic soluble aliphatic polyisocyanate.

  • Patent number: 4561738
    Abstract: A field tester wherein a patient's tested eye is located at the center of an interior hemisphere defining a projection surface and wherein a light spot is projected onto said surface from an eccentric location is disclosed. Optics in common with the projector assure that the off-center projected light is of constant intensity and diameter as selected for each test sequence according to test criteria. Specifically, a filament light source is projected to a collimating lens. The light source is re-imaged to a system lens stop. There is a movable aperture between the collimating lens and the first lens of telescopic optics for projecting the image of the aperture onto the projection surface of the sphere. By using a coordinate transform to predict the distance from the point of light source projection to the projection surface of the sphere, the movable aperture is registered to a conjugate distance with respect to the telescope optics.

  • Patent number: 4290262
    Abstract: The ducting extending a substantial axial length of a gas turbine engine is faired to transition the annular flows of the core engine and fan to a rectangular separate flow in a pair of two-dimensional exhaust nozzles so as to control each flow individually. Each flow is judiciously located to achieve noise control and infrared suppression.

  • Patent number: 3999514
    Abstract: An auger fed magnetic brush developer wherein two parallel augers continuously recirculate the developer mix and cause the mix to be enriched with toner prior to its being returned to the magnetic brush roll.A supply auger communicates with the brush roll along its entire length and directly elevates the mix to a lower part of the brush roll's surface. This supply auger includes four flutes of a pitch equal to one-half the length of the brush roll. This auger flute arrangement insures that a uniform supply of mix is presented to the brush roll along its entire length. In addition, this supply auger construction insures that a uniform supply of enriched mix is presented to the brush roll along its entire length, since the gradually depleting carrier tends to be presented to the brush roll a minimum number of times, for example three, prior to its exiting one end of the supply auger.The carrier exiting the supply auger enters a turnaround compartment whereat new toner is added.
