| 20080266561 | OPTICAL GAIN APPROACH FOR ENHANCEMENT OF OVERLAY AND ALIGNMENT SYSTEMS PERFORMANCE - A resultant image of a grating target may be obtained by dividing an image of the target into first and second portions and optically modifying the first and/or second portion such that a final image formed from their combination is characterized by a Moiré pattern. The resultant image may be analyzed to determine a shift in the grating target from a shift in the Moiré pattern. Optical alignment apparatus may include a first beam splitter, an image transformation element optically coupled to the first beam splitter, and a second beam splitter. The first beam splitter divides an image of a grating target into first and second portions. The second beam splitter combines the first portion and the second portion. The image transformation element optically modifies the first and/or second portion such that a final image formed from their combination is characterized by a Moiré pattern. | 10-30-2008 |
| 20090279091 | TARGET DESIGN AND METHODS FOR SCATTEROMETRY OVERLAY DETERMINATION - Disclosed are methods and apparatus for determining overlay error. Radiation that is scattered from each of a plurality of cells of a target is measured. Each cell includes at least a first grating structure formed by a first process and a second grating structure formed by a second process and wherein each cell has a predefined offset between such each cell's first and second grating structures. The first and second grating structures of the different cells have different predefined offsets, and each predefined offset of each cell is selected to cause one or more terms to be cancelled from a periodic function that represents radiation scattered and measured from each cell. The scattered radiation of each cell is represented with a periodic function having a plurality of unknowns parameters, including an unknown overlay error, and the unknown overlay error is determined based on the plurality of periodic functions for the plurality of cells. | 11-12-2009 |
| 20100175033 | SCATTEROMETRY METROLOGY TARGET DESIGN OPTIMIZATION - A metrology target design may be optimized using inputs including metrology target design information, substrate information, process information, and metrology system information. Acquisition of a metrology signal with a metrology system may be modeled using the inputs to generate one or more optical characteristics of the metrology target. A metrology algorithm may be applied to the characteristics to determine a predicted accuracy and precision of measurements of the metrology target made by the metrology system. Part of the information relating to the metrology target design may be modified and the signal modeling and metrology algorithm may be repeated to optimize the accuracy and precision of the one or more measurements. The metrology target design may be displayed or stored after the accuracy and precision are optimized. | 07-08-2010 |
| 20110051116 | Substrate Matrix To Decouple Tool And Process Effects - A method of characterizing a process by selecting the process to characterize, selecting a parameter of the process to characterize, determining values of the parameter to use in a test matrix, specifying an eccentricity for the test matrix, selecting test structures to be created in cells on a substrate, processing the substrate through the process using in each cell the value of the parameter as determined by the eccentric test matrix, measuring a property of the test structures in the cells, and developing a correlation between the parameter and the property. | 03-03-2011 |
| 20110069312 | METROLOGY SYSTEMS AND METHODS - Various metrology systems and methods are provided. | 03-24-2011 |

| 20090184275 | FLUID HANDLING DEVICE AND METHOD OF MAKING SAME - A fluid handling device, such as a needlefree access device, includes a housing having an inlet and an inlet channel; and a flow control member comprising a combination outlet, biasing and piston member. The flow control member includes a piston section moveable between a closed position in which the piston section is in the inlet channel and an open position in which the piston section is inside the housing below the inlet channel but allows fluid to flow through the inlet channel; a biasing section connected to the piston section that normally biases the piston section into the inlet channel; and an outlet section connected to the biasing section having an outlet fitting in fluid communication with the inside of the housing. The piston section, biasing section and outlet section are connected together such that they can be handled as one piece when assembled with the housing to make the needlefree access device. The access device can be configured as a Y-site access device, or used on other devices such as an IV bag. A check valve made by a two shot molding process is also disclosed. | 07-23-2009 |

| 20090147218 | PUPILLARY REFLEX IMAGING - A method, system and device for recording image data for a pair of eyes exposes to a series of flashes that includes flashes that vary chromatically is provided. More particularly, one eye is exposed to the series of flashes, and the resulting pupillary reflexes of both eyes are concurrently recorded. | 06-11-2009 |
| 20090213329 | EVALUATING PUPILLARY RESPONSES TO LIGHT STIMULI - Solutions for evaluating the pupillary responses of a patient are disclosed. An illustrative method includes alternately exposing a first eye and a second eye of the patient to light stimulation in successive intervals, the light stimulation provided by at least one light source controlled by at least one computing device; concurrently capturing, with at least one image device controlled by the at least one computing device, image data of the first eye and the second eye during the exposing; and using the at least one computing device to perform the following: determine a center point of the first eye within the image data of the first eye and a center point of the second eye within the image data of the second eye; obtain image data of a first half of the first eye having an edge defined by a line of pixels intersecting the determined center point of the first eye; obtain image data of a second half of the second eye, the second half of the second eye opposing the first half of the first eye and having an edge defined by a line of pixels intersecting the determined center point of the second eye; create a composite image including the image data of the first half of the first eye and the image data of the second half of the second eye; and provide the composite image for evaluation. | 08-27-2009 |

| 20100068241 | RECONSTITUTED MINERALIZED CARTILAGE TISSUE - A biological material comprising a continuous layer of cartilaginous tissue reconstituted in vitro which contains components associated with cartilage mineralization. The biological material may be cultured with a mineralizing agent to form a mineralized biological material. The mineralized biological material is characterized by having a biochemical composition and physiological organization substantially similar to the deep and contiguous calcified cartilage zones of articular cartilage found in animals in vivo. Methods for preparing the biological materials and methods of using the biological materials are described. | 03-18-2010 |
| 20100234955 | FIBROUS SCAFFOLD FOR USE IN SOFT TISSUE ENGINEERING - The present invention relates to a fibrous scaffold for use as a substrate in soft tissue applications, in particular for preparing annulus fibrosus (AF) tissue. In aspects, the present invention also relates to an engineered biological material comprising AF tissue; constructs comprising one or more engineered biological materials; methods for producing the biological materials and constructs; and methods of using the biological materials and constructs. | 09-16-2010 |

| 20100058163 | Spreadsheet system and method for managing photos - A spreadsheet system stores objects and formulas in the cells of the spreadsheet, along with metadata tags. Each cell may contain multiple objects (such as a group of photos). Drag-and-drop user actions automatically change tags associated with the moved objects based on a formula stored in the target cell if a forcing semantics mode is active, or automatically change a formula stored in the target cell if a non-forcing semantics mode is active. A formula in a cell selects a set of objects and may include set operators such as union, intersection, and minus. The formula may also filter sets to select a subset based on specified tag attributes of objects. The display of the spreadsheet adaptively selects a subset of objects to render in a cell and appropriately scales photos for optimal viewing. | 03-04-2010 |
