Patents by Inventor Tsuyoshi Misawa

Tsuyoshi Misawa 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).

  • Nuclear material detection device and nuclear material detection method
    Patent number: 10101283
    Abstract: A nuclear material within a container is to be detected. Included are: a neutron source for generating neutrons emitted toward the container; a detection section capable of detecting neutrons including primary neutrons emitted from the neutron source and secondary neutrons generated through a nuclear fission reaction of the nuclear material; and a processing section for performing a reactor noise analysis process based on data obtained through detecting of neutrons by the detection section. The neutron source generates neutrons in a pulsatile manner. The processing section performs the reactor noise analysis process based on data obtained by excluding, from time series data obtained through detecting of neutrons by the detection section, data of a time range including a generation time of the neutrons generated by the neutron source in the pulsatile manner.
    Type: Grant
    Filed: August 28, 2013
    Date of Patent: October 16, 2018
    Assignee: KYOTO UNIVERSITY
    Inventors: Kai Masuda, Tsuyoshi Misawa, Yoshiyuki Takahashi, Takahiro Yagi
