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):
    Ken D. Sauer, Charles A. Bouman, Jean-Baptiste Thibault, Jiang Hsieh
    Patent Number:
    US 6907102 B2
    Description:

    A multi-slice computed tomography imaging system is provided including a source that generates an x-ray beam and a detector array that receives the x-ray beam and generates projection data. A translatable table has an object thereon and is operable to translate in relation to the source and the detector array. The source and the detector array rotate about the translatable table to helically scan the object. An image reconstructor is electrically coupled to the detector array and reconstructs…

    Patent Number:
    US 8416914 B2
    Description:

    A non-transitory computer readable storage medium having stored thereon a computer program having instructions, which, when executed by a computer, cause the computer to acquire a set of projection data corresponding to a plurality of image voxels and to calculate coefficients of a regularizing function configured to penalize differences between pairs of the plurality of voxels that are not immediate neighbors. The instructions also cause the computer to iteratively reconstruct an image from …
