Patents by Inventor KOTARO MIZUNUMA

KOTARO MIZUNUMA 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).

  • Security management device, security management method, and computer program executed by security management device
    Patent number: 11711387
    Abstract: A security management device includes a management unit, a determination unit, and an output unit. The management unit is configured to manage an anomaly location of an anomaly in a system in which a plurality of electronic controllers are connected through a network, and an anomaly amount in the anomaly location. The determination unit is configured to determine whether or not to implement countermeasures against the anomaly based on the anomaly location and the anomaly amount. The output unit is configured to output an instruction based on a determination result by the determination unit.
    Type: Grant
    Filed: March 3, 2021
    Date of Patent: July 25, 2023
    Assignee: DENSO CORPORATION
    Inventors: Kotaro Mizunuma, Takeshi Nakamura, Takeshi Sugashima

  • Thermoelectric conversion element
    Patent number: 9461232
    Abstract: A thermoelectric conversion element includes a magnetic body and an electromotive component. The magnetic body has a pipe shape. The electromotive component is arranged to at least one of an outer surface, an inner surface, and an inside of the magnetic body. The electromotive component contains a material having a spin orbit coupling. The magnetic body is magnetized in an axial direction and has a temperature gradient in a radial direction. The electromotive component is spirally arranged around the magnetic body along a circumferential direction.
