Publication number: 20060285072Abstract: Methods of manufacturing hybrid contact lenses using a mold are provided. The methods include pouring liquefied resin of a substantially rigid material within an inner section, curing the substantially rigid material, pouring liquefied resin of a substantially flexible material within an outer section and curing the substantially flexible material. In some embodiments, a wall disposed between the rigid and flexible materials is angled and/or bent to increase bonding strength between the rigid and flexible sections. The curing steps involve the application of heat, UV light, or a combination of both heat and UV light.Type: ApplicationFiled: May 3, 2006Publication date: December 21, 2006Inventors: Ali Dahi, Barry Chen, Joe Collins, Jerome Legerton

Publication number: 20060238712Abstract: A hybrid contact lens comprises a central zone comprising a substantially rigid, gas permeable material having a DK of at least 30, a relatively soft peripheral zone and an intermediate zone comprising a film or coating that is created around the central zone, and then cured. The film facilitates chemical bonding between the central zone and the peripheral zone, and also provides a protective barrier to prevent modification of the physical characteristics of the central zone. The film may be created by soaking the central zone in a chemical solution for a predetermined amount of soaking time.Type: ApplicationFiled: June 8, 2006Publication date: October 26, 2006Inventors: Ali Dahi, Barry Chen, Joe Collins, Jerome Legerton, Ramezan Benrashid

Patent number: 7003070Abstract: In an upright CT scanner, an X-ray source and a two-dimensional digital X-ray detector are mounted on a rotating platform with a vertical axis of rotation. During scanning, the X-ray source and the detector are on opposite sides of the rotational axis for orbiting about a body to thereby scan it with pyramid-shaped X-ray beam. During scanning, the source and detector can be jointly translated along a horizontal axis that is perpendicular to the rotation axis and parallel to the detector surface, to scan a specific part of a body that is not centered or a body that is too large. The mounting height and distance of source and the detector can also be adjusted.Type: GrantFiled: August 3, 2004Date of Patent: February 21, 2006Inventors: William Barry Chen, Jason Andrew Chen
