| 20100038813 | DEVICES AND PROCESSES FOR PERFORMING DEGASSING OPERATIONS - A preferred process for degassing a mold piece includes inserting the mold piece into an internal volume within a canister, sealing the internal volume, drawing a vacuum in the internal volume, and introducing into the internal volume a gaseous fluid suitable for degassing the mold piece. | 02-18-2010 |
| 20110248415 | PROCESS FOR MANUFACTURE OF A THERMOCHROMIC CONTACT LENS MATERIAL - Disclosed in this specification is a process for manufacturing a thermochromic contact lens. The process includes (1) selecting a photoinitiator that absorbs at a first wavelength and at least one thermochromic dye that displays substantial absorption at the first wavelength when the dye is at a first temperature and exhibits at least an 80% reduction in absorbance at the first wavelength at a second temperature, (2) maintaining the reaction mixture at the second temperature and (3) providing cure light that includes the first wavelength. | 10-13-2011 |
| 20110249234 | CONTACT LENSES DISPLAYING REDUCED INDOOR GLARE - The present invention relates to contact lenses which reduce indoor glare and provide improved comfort to the wearer. | 10-13-2011 |
| 20110249235 | PUPIL-ONLY PHOTOCHROMIC CONTACT LENSES DISPLAYING DESIRABLE OPTICS AND COMFORT - A method for making a hydrogel, photochromic contact lens including supplying a first lens composition comprising a contact lens monomer and a photochromic material to a front contact lens mold and supplying a second lens composition to said contact lens mold wherein the viscosity of said first composition is at least about 1000 cp greater than the viscosity of said second contact lens composition, and the makeup of said second composition matches the of said first composition to reduce strain between said compositions of the resulting lens. | 10-13-2011 |

| 20100232747 | Assembly With An Optical Fiber Alignment - The invention refers to an optical fiber connector with a support member and a ferrule for receiving an optical fiber and fixed to the support member. The optical fiber is embedded in the ferrule. An end face of the optical fiber is arranged on the support member, while an alignment element is connected with the support member. The end face of the optical fiber abuts with the alignment element, whereby the alignment element aligns the end face of the optical fiber relative to a predetermined optical path. | 09-16-2010 |

| 20090285535 | OPTICAL INTERFACE - An optical interface for interfacing a first optical component and a second optical component, said optical interface comprising an optical clear material having at least the following features: (a) a first lens for interfacing with said first optical component; (b) a second lens for interfacing with said second optical component; (c) a reflective surface optically coupling said first and second lenses; and (d) wherein at least said first lens is eccentric, said second lens is eccentric, or said reflective surface is curved. | 11-19-2009 |
| 20110228259 | OPTICAL FIBER ALIGNMENT MEASUREMENT METHOD AND APPARATUS - A measurement system comprising an analog position sensitive device is provided that can measure the XY position of a plurality of light beams at very high resolution. In accordance with one exemplary associated method, a connector bearing one or more optical fibers is fixedly positioned before a position sensing detector so that light emanating from the ends of the optical fibers will strike the position sensing detector. A light beam is passed through at least one opening in the connector, such as a guide pin hole onto the detecting surface of the PSD to establish the position of the connector. Next, each optical fiber in the connector is individually illuminated sequentially so that the light emanating from the fiber falls on the position sensing detector. The locations of all of these light beams striking the PSD are compared to position of the light beam passed through the guide pins and/or to each other to determine if all the fibers are in the correct positions relative to the connector. In addition, it is possible to simultaneously measure the magnitude of the light emanating from each fiber in order to measure the quality of the light transmission through the connector/cable assembly. | 09-22-2011 |

| 20100264876 | METHOD OF CHARGING AND USING AN ASEPTIC BATTERY ASSEMBLY WITH A REMOVABLE BATTERY PACK - A battery assembly with a housing that contains a removable battery pack. The housing, which is sterilzable, has a head designed to couple to a power consuming device. The battery pack, which is not sterlizable, contains at least one rechargeable cell. The battery pack has a head dimensioned to fit the same charger socket that can receive a sterlizable battery. The battery pack has contacts that abut charger contacts. The housing has internal contacts. Collectively, the housing and battery pack are shaped so that, when the battery pack seats in the housing, the battery pack contacts abut the housing internal contacts. The housing internal contacts are connected to the housing external contacts for supply power to the power consuming device. A cover selectively holds the battery pack in the housing chamber. | 10-21-2010 |

| 20110288482 | SAFETY NEEDLE SYSTEM OPERABLE WITH A MEDICAL DEVICE - A safety needle system operable with a medical device includes: a housing with a needle mount having a needle; and a sheath telescopically engaged with the housing and surrounding the needle such that the sheath operates in a retracted position, in which the sheath exposes the needle, and an extended position, in which the sheath surrounds the needle. The sheath is coupleable to the medical device such that removal of the needle from the medical device draws the sheath over the needle, transitioning the sheath from the retracted position to the extended position. In one embodiment, the system includes a slider engaged with the sheath and/or housing and including a restraint that engages and disengages the sheath to respectively reinforce and weaken the coupling of the sheath and medical device. In another embodiment, the sheath includes a longitudinal track that slidingly engages a setting of the housing between sheath positions. | 11-24-2011 |
