Publication number: 20180095936Abstract: A method, system and computer program product for optimizing a manufacturing or fabrication process. A set of parameters for a selected model is received. A prior distribution of values for the model parameters is adopted which summarizes any known information for the model parameters. A utility function which reflects a purpose of an experiment is specified. After selecting an experimental design from a set of experimental designs and selecting experimental data from a sample space of data based on the selected experimental data, a Bayesian technique is used to calculate a posterior distribution of values for the model parameters based on the selected experimental data and the prior distribution of values for the model parameters. In response to the model uncertainty reaching a desired threshold, the posterior distribution of values for the model parameters is selected to be used to adjust the manufacturing/fabrication process to manufacture/fabricate a device.Type: ApplicationFiled: October 5, 2016Publication date: April 5, 2018Inventors: Roger T. Bonnecaze, Meghali Chopra

Publication number: 20100053578Abstract: A lithography process for creating patterns in an activating light curable liquid using electric fields followed by curing of the activating light curable liquid is described. The process involves the use of a template that is formed of non-conductive and electrically conductive portions. The template is brought into close proximity to the activating light curable liquid on the substrate. An external electric field is applied to the template-substrate interface while maintaining a uniform, carefully controlled gap between the template and substrate. This causes the activating light curable liquid to be attracted to the raised portions of the template. Activating light is applied to the curable liquid while an electric field is applied to the template to create a patterned layer on the substrate.Type: ApplicationFiled: August 20, 2004Publication date: March 4, 2010Applicant: Molecular Imprints, Inc.Inventors: Sidlgata V. Sreenivasan, Roger T. Bonnecaze, Carlton Grant Willson

Publication number: 20080305440Abstract: The present invention is directed to an apparatus for patterning a liquid on a substrate, with the apparatus including, a template having a pair of spaced-apart recessions with a protrusion disposed therebetween, with the protrusion being spaced-apart from the substrate a first distance and each of the pair of spaced-apart recessions being spaced-apart from the substrate a second distance, with the second distance being greater than the first distance; and a source of voltage in electrical communication with the template to produce an electric field between the template and the substrate, with a strength of the electrical field being inversely proportional to the first and second distances.Type: ApplicationFiled: March 20, 2008Publication date: December 11, 2008Applicant: The Board of Regents, The University of Texas SystemInventors: Carlton G. Willson, Sidlgata V. Sreenivasan, Roger T. Bonnecaze

Patent number: 6964793Abstract: A high-throughput lithography process for creating high-resolution patterns in a polymerizable composition using carefully controlled electric field followed by curing of the polymerizable composition is described. The process involves the use of a template that includes the desired patterns. This template is brought into close proximity to the polymerizable composition on the substrate. An external electric file is applied to the template-substrate interface while maintaining a uniform, carefully controlled gap between the template and substrate. This causes the polymerizable composition to be attracted to the raised portions of the template. By appropriately choosing the various process parameters such as the viscosity of the polymerizable composition, the magnitude of the electric field, and the distance between the template and substrate, the resolution of the structures formed in the liquid may be controlled to conform to that of the template.Type: GrantFiled: May 16, 2001Date of Patent: November 15, 2005Assignee: Board of Regents, The University of Texas SystemInventors: Carlton Grant Willson, Sidlgata V.

Patent number: 6579690Abstract: One embodiment of the invention is a method for obtaining an estimate of an analyte concentration in a first fluid. First, measurements of an analyte concentration in a second fluid are obtained using a sensing device. An analyte concentration estimate in the first fluid is determined from these measurements by minimizing the relation: f[b]=x2[b]+&lgr;&PSgr;[b], where b is a vector representing analyte concentration in the first body fluid, X2[b] is a function representing a fit between the estimates and the measurements, &lgr; is a weighting function, and &PSgr;[b] is a function indicating smoothness of the analyte concentration estimates in the first fluid. Another embodiment includes a sensing device for obtaining the measurements of an analyte concentration in the first fluid and a processor configured and arranged to determine the analyte concentration in the first body fluid according to this method.Type: GrantFiled: July 24, 2000Date of Patent: June 17, 2003Assignee: TheraSense, Inc.Inventors: Roger T.

Publication number: 20030100040Abstract: A method for obtaining an estimate of an analyte concentration in a first fluid from an analyte concentration in a second fluid is disclosed. The method includes obtaining measurements of an analyte concentration in a second fluid by using a sensing device. The analyte concentration estimate in the first fluid is determined from these measurements. Also disclosed is a sensing device for obtaining the measurements of an analyte concentration in the first fluid and a processor configured and arranged to determine the analyte concentration in the first body fluid according to this method. This method and device can be used, for example, to determine blood glucose concentration from measurements of the glucose concentration in subcutaneous tissue. These measurements may be made using in vitro or in vivo samples. In some instances, a subcutaneously implanted sensing device, such as electrochemical sensor, is used to make the measurements.Type: ApplicationFiled: November 11, 2002Publication date: May 29, 2003Applicant: TheraSense Inc.Inventors: Roger T.
