20090268158 | Diffractive Multifocal Lens Having Radially Varying Light Distribution - The present invention provides improved ophthalmic lenses and methods for their design and use. Monofocal and multifocal diffractive ophthalmic lenses having reduced light scatter and/or improved light energy distribution properties are provided. These properties are provided by the diffractive profiles of the invention, often having subtlely shaped echelettes with appropriately curving profiles. Light scatter may be generated by the sharp corners associated with vertical steps between adjacent conventional diffractive echelettes. Smooth diffractive profiles of the invention reduce light scatter. Light energy directed towards non-viewing diffractive orders may have a unwanted effects on vision quality. Diffractive profiles of the invention may limit the light energy in certain, selected orders, thereby improving viewing quality and mitigating unwanted effects such as dysphotopsia. Diffractive profiles of the invention can also vary the light energy distributed between individual echelettes, providing additional advantages in various viewing situations. | 10-29-2009 |
20100281021 | CUSTOMIZED MULTIFOCAL OPHTHALMIC LENS - System and method for customizing multifocal ophthalmic lenses, such as an intraocular lens (IOL) or the like, that may be tailored for an individual patient or group of patients beyond the selection of a particular IOL power. One or more eye factors of the patient are determined, a set of different multifocal intraocular lenses having a similar base power are determined based on the eye factors, and a multifocal intraocular lens is selected for the patient from the set based on the eye factors. | 11-04-2010 |
20110109875 | DIFFRACTIVE MULTIFOCAL LENS HAVING RADIALLY VARYING LIGHT DISTRIBUTION - The present invention provides improved ophthalmic lenses and methods for their design and use.

20120296426 | HAPTIC FOR ACCOMMODATING INTRAOCULAR LENS - A haptic is provided for use in an accommodating intraocular lens. The haptic has multiple filaments, each connected to the edge of the optic at one end. Each filament has a shape that conforms to an equatorial region of the capsular bag. The haptic couples the forces exerted by the capsular bag of the eye during accommodation radially to the edge of the optic, produce a diametric expansion or compression of the optic. This diametric motion distorts the optic, producing a change in any or all of the anterior radius, the posterior radius, and the thickness. These changes affect the power of the lens and/or location of the image. The haptic may optionally have a thin membrane joining the filaments at the optic end, and may optionally have a connecting ring that joins the filaments at the end opposite that of the optic. | 11-22-2012 |
20130226294 | Ophthalmic Devices, Systems, And Methods For Optimizing Peripheral Vision - The present invention relates to devices, systems, and methods for optimizing peripheral vision. In particular, methods are disclosed which include utilizing particular characteristics of the retina in optimizing peripheral vision. Additionally, various IOL designs, as well as IOL implantation locations, are disclosed which optimize peripheral vision. | 08-29-2013 |

20080301174 | Data structure, system and method for knowledge navigation and discovery - Data structures, systems, methods and computer program products that enable precise information retrieval and extraction, and thus facilitate relational and associative discovery are disclosed. The present invention utilizes a novel data structure termed a “Knowlet” which combines multiple attributes and values for relationships between concepts. While texts contain many re-iterations of factual statements, Knowlets record relationships between two concepts only once and the attributes and values of the relationships change based on multiple instances of factual statements, increasing co-occurrence or associations. The present invention's approach results in a minimal growth of the Knowlet space as compared to the text space and it thus useful where there is a vast data store, a relevant ontology/thesaurus, and a need for knowledge navigation and (relational, associative, and/or other) knowledge discovery. | 12-04-2008 |

20110179026 | Related Concept Selection Using Semantic and Contextual Relationships - A system and method for ranking results derived from various analytical processes for a concept selector is disclosed. The method ranks the concepts extracted for information input to a concept selector by semantic mapping and contextual mapping techniques. Information is input to a concept selector. The concept selector may then analyze the input information to select list of matched synonyms, generate concept relationship maps, concept database maps for the matched concepts from its databases. In addition, content provided from the web page may also be analyzed by the concept selector for mapping the concepts. Further, obtained list of matched terms, keywords and concepts are sent to the ranking module for ranking the results. The ranking module may rank the results obtained based on pre-defined filtering techniques such as semantic rules, business rules and so on. The ranked results are output by the concept selector. | 07-21-2011 |
20110218993 | SEMANTIC PAGE ANALYSIS FOR PRIORITIZING CONCEPTS - Embodiments disclose a method of obtaining relevancy scores for concepts found on a page of content. Methods disclosed rely on connectivity of concepts found in a page in relation to connectivity of the same concepts with other concepts in general, and the semantic relationships between the concepts found on a page to obtain relevancy of concepts. | 09-08-2011 |
