| 20090003896 | METHOD AND APPARATUS FOR ENHANCED SHEET STRIPPING - An enhanced sheet stripping method and apparatus for stripping toner image carrying copy sheets from a surface of a moving heated fusing member forming a fusing nip. The apparatus includes (a) a moving assembly for moving a cut sheet towards the fusing nip; (b) a sheet curling device positioned upstream of the fusing nip relative to movement of the cut sheet for inducing a desired pre-curl in the cut sheet before the cut sheet enters the fusing nip; and (c) a sheet stripping device positioned downstream of the fusing nip for stripping the cut sheet from contact with the surface of the moving heated fusing member as the cut sheet exits the fusing nip. The method includes inducing a desired curl in the cut sheet before the cut sheet enters the fusing nip and enhanced stripping the cut sheet from contact with the surface of the fuser roll as the cut sheet exits the fusing nip. | 01-01-2009 |

| 20080219317 | GAS-PURGED LASER SYSTEM AND METHOD THEREOF - A gas-purged laser system and method of gas-purging a laser system are disclosed. One embodiment of the laser system comprises an excimer refractive surgical laser system having a laser beam optical path configured to allow purging of a portion of a volume enclosing the laser beam optical path with a gas, and a gas generator, operable to generate the purging gas and provide the gas to the volume portion. The portion of the volume can be the entire volume enclosing the laser beam optical path or a selected portion thereof. The gas can be nitrogen gas and the gas generator can be a self-contained nitrogen generator as will be known to those having skill in the art. Embodiments can further comprise a controller for controlling the flow of purging gas in response to received signals representative of various parameters, such as temperature, oxygen level, pressure, humidity and flow rate. | 09-11-2008 |
| 20100022994 | LIQUID FILLED INDEX MATCHING DEVICE FOR OPHTHALMIC LASER PROCEDURES - There is provided a device for use as an interface between a laser surgery device and the eye of a patient. The device is filled with a liquid that matches the index of refraction of the eye. The device further has a curved lens that follows the curvature of the outer surface of the patient's eye. In this manner the interface device, through which the laser beam must travel, has essentially the same index of refraction as the eye. | 01-28-2010 |
| 20100022996 | METHOD AND SYSTEM FOR CREATING A BUBBLE SHIELD FOR LASER LENS PROCEDURES - There is provided a system and method for creating a layer of bubbles in the posterior portion of the lens of the eye. This layer of bubbles in the posterior portion of the lens functions as a shield protection structures of the eye that are located posteriorly from the lens from being damaged or injured by the use of the laser in subsequent activities upon the lens, such as the performance of a laser assisted capsulotomy. Thus, the bubble shield reduces the risk to posterior structures during laser procedures on the lens of the eye. | 01-28-2010 |
| 20100292678 | SYSTEM AND METHOD FOR PROVIDING LASER SHOT PATTERNS TO THE LENS OF AN EYE - There is provided a system, apparatus and methods for developing laser systems that can create precise predetermined shot patterns for providing areas of varying softness in the lens of an eye. These areas of varying softness may have shapes that correspond to instruments used to remove material from the lens of the eye. There is further provided a multiplicity of spheres pattern, which may provide for bubble formation which in turn lubricates the lens material for removal after sectioning. | 11-18-2010 |
| 20110022035 | LIQUID HOLDING INTERFACE DEVICE FOR OPHTHALMIC LASER PROCEDURES - There is provided a self-adjusting interface device for use with laser surgery devices. The device may be filled with a liquid that matches the index of refraction of the cornea of the eye. The device has the ability to adjust to varying curvatures of the eye and is configured so that when attached to the eye the laser surgery device will be able to deliver a therapeutic laser beam to the limbus region of the eye. | 01-27-2011 |
