Patent number: 7822263Abstract: Systematic use of infrared imaging characterizes marks made on items and identifies the particular marking tool with better accuracy than use of visual imaging. Infrared imaging performed in total darkness eliminates shadows, glint, and other lighting variations and artifacts associated with visible imaging. Although normally used to obtain temperature measurements, details in IR imagery result from emissivity variations as well as thermal variations. Disturbing an item's surface texture creates an emissivity difference producing local changes in the infrared image. Identification is most accurate when IR images of unknown marks are compared to IR images of marks made by known tools. However, infrared analysis offers improvements even when only visual reference images are available.Type: GrantFiled: October 13, 2009Date of Patent: October 26, 2010Inventor: Francine J. Prokoski

Publication number: 20100266197Abstract: What is disclosed is a novel system and method for determining which hole punch die is installed on a multifunction document reproduction device. A document scanner of a document reproduction system is used to scan a sample page that has been hole-punched by the presently installed punch die. The pattern of die holes on the punched test page is examined and compared to known punch die patterns. The method compares the current punch unit with bindings loaded in a hopper for the print/copy job. Information about the currently installed hole punch die is displayed on a graphical user interface so the user can confirm the print/copy job prior to the time of submission. The user can then accept the current hole punch configuration or change the unit to another before releasing their print/copy job. The method ensures that the selected punch pattern is compatible with other print/copy job finishing selections.Type: ApplicationFiled: April 15, 2009Publication date: October 21, 2010Applicant: Xerox CorporationInventor: J.

Patent number: 7813537Abstract: Myocardial tissue tracking techniques are used to project or guide a single manually-defined set of myocardial contours through time. Displacement encoding with stimulated echoes (DENSE), harmonic phase (HARP) and speckle tracking is used to encode tissue displacement into the phase of complex MRI images, providing a time series of these images, and facilitating the non-invasive study of myocardial kinematics. Epicardial and endocardial contours need to be defined at each frame on cine DENSE images for the quantification of regional displacement and strain as a function of time. The disclosed method presents a novel and effective two dimensional semi-automated segmentation technique that uses the encoded motion to project a manually defined region of interest through time. Contours can then easily be extracted for each cardiac phase.Type: GrantFiled: May 14, 2007Date of Patent: October 12, 2010Assignees: Siemens Medical Solutions USA, Inc., University of Virginia Patent Foundation, University of Cape TownInventors: Frederick H Epstein, Ernesta M Meintjes, Bruce S Spottiswoode

Patent number: 7764823Abstract: A system and method for automatically detecting cracks in components produced by a stamping process. A substantially uniform backlighting of the component can be produced, even when direct backlighting is partially blocked by structure used to support the component during inspection. One or more image detectors simultaneously image the component from a top side while it is backlit. One or more images of the current component are then compared to a master image of the component. Light passing through or visible through cracks in the component will cause the system to see a difference between the current image(s) of the component and the master image(s), thereby indicating a crack(s). A user is automatically notified upon detection of a crack.Type: GrantFiled: February 16, 2007Date of Patent: July 27, 2010Assignee: Honda Motor Co., Ltd.Inventors: Milan Jurich, Molly Hamilton, Shaun McCann
