20080212022 | SERIES OF ASPHERICAL CONTACT LENSES - The present invention provides a series of aspherical contact lenses, each lens having a first central optical zone on its anterior surface and a second central optical zone on its posterior surface. Both central optical zones are aspherical surfaces. The first central optical zone is designed to have a surface which provides a target optical power and an optical power profile selected from the group consisting of (1) a substantially constant optical power profile, (2) a power profile mimicking the optical power profile of a spherical lens with an identical targeted optical power, and (3) a power profile in which lens spherical aberration at 6 mm diameter is from about 0.65 diopter to about 1.8 diopters more negative than spherical aberration at 4 mm diameter. | 09-04-2008 |
20090040458 | Toric contact lens with improved posterior surface design - Ophthalmic lenses for correcting astigmatism having a posterior surface with a central optic zone, a peripheral zone, and a blending zone therebetween. The surface of the central zone may be asphero-toric and the surface of the peripheral zone aspheric, with these flatter slopes smoothening out the transition between the central and peripheral zones. The blending zone gradually transitions the curvatures of the central and peripheral zones to further smoothen out the central-to-peripheral-zone transition. | 02-12-2009 |
20090115963 | TORIC LENS DESIGN - This invention is related to contact lenses. In particular, the present invention is related to a toric contact lens design with thickness zones in the carrier portion of the lens for increased rotational stability. | 05-07-2009 |
20100036489 | LENS DESIGN AND METHOD FOR PREVENTING OR SLOWING THE PROGRESSION OF MYOPIA - A lens is provided that is capable of preventing or slowing the progression of myopia when worn by a person. The lens has a power profile that reduces on-axis and off-axis hyperopic defocus created by the optics of the eye by creating on-axis and off-axis myopic defocus. The on-axis and off-axis myopic defocus is created by providing light rays that pass through a central vision region of the optical portion and light rays that pass through a peripheral region of the optical portion an increase in positive (plus) power. The overall effect is to prevent or slow the progression of myopia without any perceptible degradation in the person's central vision. | 02-11-2010 |
20110032474 | LENS HAVING AN OPTICALLY CONTROLLED PERIPHERAL PORTION AND A METHOD FOR DESIGNING AND MANUFACTURING THE LENS - A contact lens or phakic IOC lens is provided with a peripheral portion that has a power profile that provides optical control of peripheral vision images. Typically, the central portion of the lens is also provided with optical control. The power profile of the lens at the boundary of the central and peripheral portions meets certain boundary conditions that ensure that the lens provides a desired or selected vision correction. Because the peripheral portion of the lens provides optical control that defocuses the peripheral vision image relative to the retina, the lens can be used to prevent or inhibit growth of the eye, thereby preventing or inhibiting myopia or the effects of myopia. | 02-10-2011 |
20110102737 | OPTIMIZING OPTICAL ABERRATIONS IN OPHTHALMIC LENSES - An ophthalmic lens includes spherical aberration in an amount that accounts for spherical aberration introduced into the lens during the manufacturing process and/or spherical aberration differences in the manufactured lens measured off of the eye and measured on the eye. The result is a lens-and-eye optical system is free or substantially free of spherical aberration, i.e., having only negligible spherical aberration. Because the optical system is free or substantially free of spherical aberration, there is no or only negligible coma induced by the normal misalignment of the lens optical axis and the eye's primary line of sight. The result is a lens-and-eye optical system that provides enhanced optical performance and visual quality. Also disclosed are methods of designing and manufacturing lenses with spherical aberration adjustments to account for manufacturing process changes and off-eye to on-eye differences. | 05-05-2011 |

The plurality of the writing regions can be grouped based on the feature set. | 10-23-2008 |
20080292190 | Classifying digital ink into a writing or a drawing - A method for classifying digital ink receives digital ink comprising ink strokes. A plurality of the ink strokes can be classified. A temporal line grouping is performed on a plurality of the classified ink strokes that are grouped to form a temporal line group. The temporal line group is segmented into a cluster. The cluster can be classified. | 11-27-2008 |
20090158219 | ENGINE SUPPORT FOR PARSING CORRECTION USER INTERFACES - A parsing system provides a parsed document to a user application labeling the document with indication symbols according to a scheme associated with the parsing results. Users are enabled to insert correction indicators such as handwritten gestures, icon selections, menu item selections, and the like in conjunction with the indication symbols. The document is re-analyzed performing the requested corrections such as line or block separations, line, block, word connections, etc. The operations provide support for the engine stack of the parsing system while accommodating independent user interfaces employed by the users. Insertion of correction indicators and subsequent re-analysis for correction may be performed upon user signal, in an iterative manner, or continuously. | 06-18-2009 |
20090285485 | Systems, Methods, And Computer-Readable Media for Fast Neighborhood Determinations In Dynamic Environments - Methods, systems, and computer-readable media for ascertaining neighborhood information in a dynamically changing environment, such as an electronic ink environment may include: (a) receiving data representing plural electronic ink strokes; (b) defining a first vertex associated with a first ink stroke; and (c) determining neighboring vertices to the first vertex, wherein the neighboring vertices are associated with ink stroke(s) other than the first ink stroke. Additional systems, methods, and computer-readable media may include: (a) receiving data representing plural electronic ink strokes; (b) defining plural vertices associated with the ink strokes; (c) receiving input indicating a selection of an ink component; and (d) determining at least one neighboring component by determining which ink component(s) located outside of the selection include one or more ink strokes having vertices that neighbor vertices included in the selection. | 11-19-2009 |
20100171754 | CONVERTING DIGITAL INK TO SHAPES AND TEXT - A shape expressed using digital ink is recognized and a beautified shape is inserted into a document in a native document format. A user interface (“UI”) control is displayed adjacent to the beautified shape which, when selected, will display selectable items for modifying the beautified shape. Insertion of the beautified shape may be undone, the beautified shape may be deleted, and the format of the beautified shape may be modified. Digital ink may also be received that corresponds to text. The digital ink is inserted into a document, displayed, and the text represented by the digital ink is recognized. A UI control is displayed adjacent to the digital ink that will display one or more selectable UI items corresponding to recognition alternates. When selected, the selectable items will cause the text of the corresponding recognition alternate to be inserted into the document. | 07-08-2010 |
