Patents by Inventor Timothy P. Lodge

Timothy P. Lodge has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7999020
    Abstract: An ion gel including an ionic liquid and a block copolymer. The block copolymer includes at least three blocks, and the block copolymer forms a self-assembled ion gel in the ionic liquid. Also, thin film transistors including an ion gel insulator layer, capacitors including an ion gel insulator layer, integrated circuits including transistors including an ion gel insulator layer, and methods for forming each of these devices are described.
    Type: Grant
    Filed: November 29, 2007
    Date of Patent: August 16, 2011
    Assignee: Regents of the University of Minnesota
    Inventors: C. Daniel Frisbie, Timothy P. Lodge
  • Publication number: 20100132442
    Abstract: A device (60) and method for measuring the roughness of a playing surface are described. The device includes a carriage (12) which can travel over the playing surface, a rotatable member (80) which can roll over the playing surface, a restraint (84) which constrains the rotatable member (80) to travel with the carriage (12) and a transducer (70) coupled to the rotatable member (80) and which can generate a signal representative of the height and/or lateral translation of the rotatable member.

  • Patent number: 6433101
    Abstract: The present invention relates to the post-polymerization fluorination methods of polymers produced via ring-opening metathesis polymerization. Unlike prior art methods that result in low product yields and generally involve chemically aggressive reagents, the inventive methods produce fluorinated polymers in quantitative yields and under mild conditions. In preferred embodiments, a source of difluorocarbene is reacted with the desired polydiene to form a fluorinated polymer product. In preferred embodiments, the source of difluorocarbene is hexafluoropropylene oxide and the polydiene is poly-dicyclopentadiene (“poly-DCPD”). Fluorination and the concomitant removal of unsaturated bonds result in polymers having improved physical properties such as improved strength characteristics, enhanced oxidative and chemical stability, and low surface energies.
