Publication number: 20200163754Abstract: Apparatuses, systems, and methods for implanting an intraocular lens into an eye are described. For example, an intraocular lens injector may include a passage formed in a distal end portion of the intraocular lens injector. The passage may define an interior surface, and a ramp may be formed on the interior surface so as to cause a leading haptic of an intraocular lens (IOL) being advanced through the passage to lift above a surface of an optic of the IOL to ensure proper folding of the IOL.Type: ApplicationFiled: January 23, 2020Publication date: May 28, 2020Inventors: Kyle Brown, Tu Cam Tran, Yinghui Wu, Stephen J. Van Noy

Patent number: 10588780Abstract: Apparatuses, systems, and methods for implanting an intraocular lens into an eye are described. For example, an intraocular lens injector may include a plunger and an injector body that includes an insertion depth guard and a nozzle extending therefrom. The insertion depth guard is disposed at a distal end of the injector body to limit a distance that the nozzle penetrates the eye. The intraocular lens injector may also include a biasing element configured to generate a counterforce to distal movement of the plunger through the injector rod. An example intraocular lens injector may include a biasing element to produce a counterforce that opposes advancement of the plunger through the injector body. The counterforce provides for a more continuous advancement of the plunger while reducing or substantially eliminating abrupt changes in the rate at which the plunger is advanced through the injector body.Type: GrantFiled: February 22, 2016Date of Patent: March 17, 2020Assignee: Alcon Inc.Inventors: Stephen J. Van Noy, David Anthony Downer, Kyle Brown, Yinghui Wu

Publication number: 20170228448Abstract: Graph pattern association rules (GPARs) are proposed for social media marketing. Extending association rules for item-sets, GPARs help discover regularities between entities in social graphs, and identify potential customers by exploring social influence. The problem of discovering top-k diversified GPARs is NP-hard. A parallel algorithm is thus disclosed with accuracy bound. A parallel scalable algorithm is further disclosed that guarantees a polynomial speedup over sequential algorithms with the increase of processors.Type: ApplicationFiled: February 8, 2016Publication date: August 10, 2017Inventors: Wenfei Fan, Xin Wang, Yinghui Wu, Jingbo Xu

Patent number: 6884292Abstract: A method and apparatus are provided for batch, continuous, or semi-continuous coating of optical lenses. The method and apparatus use a plurality of carriages which are reciprocally moved in the apparatus to transfer jigs from a jig filled carriage to a lens loading arm and to load the jigs with lenses and then to transfer the jigs now containing uncoated lenses to a leading empty carriage. Using such a reciprocating motion, a leading empty carriage is now filled with jigs containing uncoated lenses and the uncoated lenses in the carriage may then be coated by dipping the carriage in a coating tank. After coating, the coated lenses are removed from the system. A similar reciprocating motion is used in the coated lens unloading section.Type: GrantFiled: January 29, 2002Date of Patent: April 26, 2005Assignee: Optima, Inc.Inventors: Zhou Yang, Yinghui Wu

Patent number: 6042754Abstract: The present invention relates to making optical articles such as opthalmic lenses by molding and, in particular, to using a continuous extrusion-compression molding method to make plastic lenses whereby a polymer melt is fed from an extruder or melting apparatus to a first die of a plurality of rotating or conveyed sequentially processed compression die sets comprising a first die and a second die. The die sets are positioned on die supports on a rotating turntable or conveying system, the lenses formed by compressing the die sets with pressing means associated with each die support, the lenses separated from the dies and the dies recycled to die loading and the melt feed step of the process and the process repeated until the desired number of lenses or other optical articles such as compact disk substrates are produced.Type: GrantFiled: October 30, 1998Date of Patent: March 28, 2000Assignee: Optima, Inc.Inventors: Zhou Yang, Yinghui Wu
