Patent number: 8510067Abstract: An improved quality assurance system and method for point-of-care testing are disclosed. The present invention provides quality assurance for laboratory quality tests performed by a blood analysis system or the like at the point of patient care without the need for running liquid-based quality control materials on the analysis system. Quality assurance of a quantitative physiological sample test system is performed without using a quality control sample by monitoring the thermal and temporal stress of a component used with the test system. Alert information is generated that indicates that the component has failed quality assurance when the thermal and temporal stress exceeds a predetermined thermal-temporal stress threshold.

Publication number: 20120253723Abstract: A method of establishing statistically valid assay means and ranges for quality control materials, used to qualify medical testing machines, utilizes tests on a new lot of quality control material to establish an assay mean, and uses data from a database of historical test results to establish an assay range.

Accordingly, an objective basis on which it can be determined whether seal imprints on documents are forged in civil and criminal cases can be provided to prevent errors which may be generated when seal imprints are inspected with the naked eyes or microscopes.Type: ApplicationFiled: November 30, 2010Publication date: September 22, 2011Inventors: Joong LEE, Young Su Lee, Jun Suk Kim, Ki Woong Moon, Byung Wook Park

Patent number: 8000519Abstract: A method of evaluating an inline inspection recipe compares the capture rate of metal pattern defects in bounding boxes arising from failed electrical test vectors to the capture rate after the bounding box is shifted. A difference between the first and second capture rates indicates whether the inline inspection recipe is valid for capturing killer defects, or if the inline inspection recipe needs to be adjusted. In a particular example, the electrical test vectors are directed at a selected patterned metal layer of an FPGA (M6), and the metal pattern defect data for the selected patterned metal layer is mapped to the bounding box determined by the electrical test vector.Type: GrantFiled: April 4, 2007Date of Patent: August 16, 2011Assignee: Xilinx, Inc.Inventors: Yongjun Zheng, David Mark, Joe W. Zhao, Felino Encarnacion Pagaduan

Patent number: 7996170Abstract: A method and apparatus that enables a user to sort data from one or more sample lots, which may be obtained via a network, such as the Internet, into a composite parameter structure. The composite parameter structure is a function of one or more parameters corresponding to one or more characteristics associated with one or more sample lots. The composite parameter structure representation may be printed, stored, or transmitted to another location. A server device that is coupled and working in conjunction with a client device may implement the present invention.Type: GrantFiled: May 14, 2009Date of Patent: August 9, 2011Assignee: Par Pharmaceutical, Inc.Inventors: Robert Ruemer, Narayan Ragunathan, Robert A.

Patent number: 7983866Abstract: A device testing system includes a detecting module, a data determining module, an address processing module, and a data obtaining module. The detecting module detects if the device testing system has been successfully connected with a device to be tested. The data determining module determines if the device testing system includes test data required by the device to be tested. The address processing module determines if an address list includes an address of the device to be tested. The data obtaining module obtains test data required by devices to be tested whose addresses are included in the address list from the remote server. A test data obtaining method of the device testing system is also provided.Type: GrantFiled: October 21, 2008Date of Patent: July 19, 2011Assignee: Hon Hai Precision Industry Co., Ltd.Inventors: Po-Jen Chi, Shu-Min Cheng

Patent number: 7974802Abstract: A method optimizes photomask inspection. After masks are manufactured, the method predicts the likelihood that the masks will be defect free based on defect criteria, etch area, etch mode, and etch tool type associated with the masks. The method skips an initial mask inspection for masks that have a predictability value above a predetermined value and performs the initial mask inspection for masks that have a predictability value below the predetermined value. After initial inspection is preformed (or skipped), a pellicle is mounted on the mask and then all masks are inspected or reinspected for defects and foreign matter.Type: GrantFiled: March 7, 2008Date of Patent: July 5, 2011Assignee: International Business Machines CorporationInventors: Karen D. Badger, Jim B. Densmore, Christopher R. Gillman, Kathleen G. Purdy, Cynthia Whiteside

Patent number: 7968354Abstract: Computer-implemented methods that include correlating a backside defect with a frontside defect detected on a specimen are provided. The defects are correlated if a portion of the backside defect on the backside of the specimen is opposite to a portion of the frontside defect on the frontside of the specimen. In particular, the defects are correlated if the portion of the backside defect is aligned with the portion of the frontside defect along an axis perpendicular to the frontside and the backside of the specimen. The method may also include altering a parameter of a process tool in response to the backside defect to reduce frontside defects on additional specimen processed in the process tool. Computer-implemented methods for analyzing data representing spatial characteristics of backside defects detected on a specimen to classify the backside defects are also provided. Analyzing the data may include spatial signature analysis of the data.Type: GrantFiled: October 3, 2003Date of Patent: June 28, 2011Assignee: KLA-Tencor Technologies Corp.Inventors: Kurt Haller, Susan S.
