Kurazo Maruoka 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).

  • Blood sugar level measuring apparatus
    Patent number: 7251517
    Abstract: Blood sugar levels are measured non-invasively based on temperature measurement. Non-invasively measured blood sugar level values obtained by a temperature measurement scheme are corrected by blood oxygen saturation and blood flow volume, thereby stabilizing the measurement data.
    Type: Grant
    Filed: June 30, 2004
    Date of Patent: July 31, 2007
    Assignee: Hitachi, Ltd.
    Inventors: Ok-Kyung Cho, Yoon-Ok Kim, Kurazo Maruoka, Hiroshi Mitsumaki
  • Blood sugar level measuring apparatus
    Publication number: 20060084853
    Abstract: Blood sugar levels are measured non-invasively based on temperature measurement. Measurement data is stabilized by correcting blood sugar level measurement values obtained by a temperature measuring system in a non-invasive manner based on the blood oxygen saturation and the blood flow volume. An LCD portion 13 is raised from a horizontal direction by an angle ? of 15° to 60° so as to prevent the generation of noise due to radiation heat from body surfaces other than the user's finger.
