20100029352 | METHOD AND SYSTEM FOR INCREASED REALISM IN VIDEO GAMES - A system and method for updating parameters of a video game is provided. As events occur in the real world that may influence a game attribute, a parameter is recorded on a server. A video game player may connect to the server and download the parameter. The parameter is stored by the video game and changes an attribute of the video game. Thus, for example, the new performance characteristics of the rising star may be recorded on the server as improved performance parameters. When these parameters are downloaded by the video game player, the video game incorporates the star-like qualities of the rising star. | 02-04-2010 |

20130326308 | PARTIAL PACKET RECOVERY IN WIRELESS NETWORKS - Systems and methods for improved packet throughput using partial packets are provided in which data recovery of partial packets of a plurality of received coded packets is performed across the plurality of received coded packets. The plurality of received coded packets, including the received partial packets, can be buffered in a memory and used in recovering the data for the partial packets. As soon as the total number of received packets (including valid and partial) becomes greater than the generation size, a decoding process can be attempted utilizing the partial packets as part of the redundancy used for data recovery. During the decoding process, the received packets are evaluated across packets instead of on a per-packet basis. | 12-05-2013 |

20090204211 | Accommodative IOL with Dynamic Spherical Aberration - The present invention is generally directed to accommodative intraocular lenses (IOLs) that exhibit a dynamic spherical aberration as a function of accommodative power. By way of example, in one aspect, the present invention provides an intraocular lens (IOL) having an anterior optical element, a posterior optical element, and a mechanism for coupling the anterior and posterior elements so as to allow axial movement of those elements relative to one another for providing accommodation when the lens is implanted in a patient's eye. Each of the anterior and the posterior elements includes at least one aspherical surface, where the asphericities of the surfaces are adapted to provide a combined spherical aberration that varies with accommodation. | 08-13-2009 |
20120158131 | ASPHERIC OPTICAL LENSES AND ASSOCIATED SYSTEMS AND METHODS - Aspheric optical lenses (e.g., intraocular lenses and contact lenses) are provided. The intraocular lens includes a body portion defining an anterior optical surface and an opposing posterior optical surface. The anterior optical surface includes a central region surrounded by a first outer region and a second outer region. The central region has a first asphericity profile. The first outer region has a second asphericity profile that is different than the first asphericity profile of the central region. The second outer region has a third asphericity profile that is different than the second asphericity profile of the first outer region. The overall asphericity profile of the optical lens provides different depths of focus for different pupil sizes. The result is an optical lens that provides increased depth of focus or pseudo-accommodation while maintaining desired optical power and performance. | 06-21-2012 |

20100211169 | INTRAOCULAR LENS CONFIGURED TO OFFSET OPTICAL EFFECTS CAUSED BY OPTIC DEFORMATION - Intraocular lenses (IOLs) and related methods. One embodiment provides an IOL which includes a lens optic and a pair of haptics. The haptics can be coupled to the lens optic and can cause compression of the lens optic when the IOL is fixated in an eye. The lens optic can have a compressed geometry, an uncompressed geometry including an aberration, and a desired geometry. The compressed geometry can be the desired geometry. The aberration can be astigmatism, coma, or spherical aberration. For instance, the aberration can be astigmatism of about 0.17 D at the spectacle plane and of about 0.25 D at the intraocular lens plane. Moreover, the haptics can define a first axis between the haptics; the lens optic can define a second axis perpendicular to the first axis; and the uncompressed geometry can differ from the compressed geometry in the vicinity of the second axis. | 08-19-2010 |
