Notre Dame Patents

Collection Details Full Record

Description

This collection brings together all of the patents assigned to the University of Notre Dame from 1952 to the present, plus other selected patents prior to 1952. Each record includes a full-text searchable and accessible PDF document for the corresponding invention. The record also includes the present-day academic department with which the inventor was or would have been associated.

Why patents? According to the University’s IDEA Center, “Part of the University’s public service mission is to ensure that the results of its research are made available for public use and benefit. This is accomplished in many ways: through educating students, publishing results of research, and ensuring that inventions are developed into useful products and services for the benefit of the public.”

“Today, our research universities play an even more vital role in creating a better future—not only by educating close to 600,000 graduate students in science and engineering every year, but also, and critically, by performing more than 15% of U.S. R&D in 2011—and according to 2012 NSF data, accounted for the majority (53%) of national basic research. This research, some basic, some applied or ‘translational’ creates new technologies, new products and services, medicines, diagnostics — the list is long and impressive — but also, this research gives rise to entire new industries.” (David Winwood, “The Importance of Patents and Academic Technology Transfer,” March 26, 2015)

The collection also includes the most famous patent associated with Notre Dame, U.S. patent 1,811,959 from 1931, “Vinyl derivatives of acetylene and method of preparing the same” — in other words, synthetic rubber. Invented by Rev. Fr. Julius Nieuwland, CSC, and assigned to DuPont, this patent did, in fact, give rise to entire new industries. More about this invention may be found at the National Inventors Hall of Fame.

These patents are one more example of the University fulfilling Rev. Fr. Sorin’s vision of becoming a “powerful force for good.”

  • Inventor(s):
    Jean-Baptiste Thibault, Charles A. Bouman, Jeffrey Allen Fessler, Ken D. Sauer
    Patent Number:
    US 7885371 B2
    Description:

    A method and system for image reconstruction of data acquired by a device such as computed tomography is provided. The method and system use a multi-stage statistical iterative reconstruction techniques to provide a three dimensional representation of the scanned object. In one embodiment, the first stage uses a projection-based reconstruction technique, such as Ordered Subset (OS) to converge on a solution for low frequency portion of the image. A subsequent stage uses a voxel-based reconstr…

    Patent Number:
    US 6768782 B2
    Description:

    An imaging system is provided including a source generating an x-ray beam and a detector array receiving the x-ray beam and generating projection data corresponding to at least a scanned portion of an object. An image reconstructor is electrically coupled to said detector array and reconstructs an image of the scanned portion of the object for a full field-of-view in response to said projection data using a dual iterative reconstruction technique. The dual iterative reconstruction technique i…

    Patent Number:
    US 8233682 B2
    Description:

    A method of improving a resolution of an image using image reconstruction is provided. The method includes acquiring scan data of an object and forward projecting a current image estimate of the scan data to generate calculated projection data. The method also includes applying a data-fit term and a regularization term to the scan data and the calculated projection data and modifying at least one of the data fit term and the regularization term to accommodate spatio-temporal information to fo…
