  • Publication number: 20190053614
    Abstract: A toothbrush includes a main body that includes a head portion with a bristle raising surface on which bristles are provided in a standing manner, a grip portion, and a neck portion. A light emission portion that emits light through a specific region of the bristle raising surface toward a tooth surface and a light reception portion that receives radiated light from the tooth surface resulting from the light, through the specific region, are provided inside of the main body. It is determined whether or not there is dental plaque on the tooth surface based on the output of the light reception portion. A light reception and condensing portion that condenses the radiated light from the tooth surface toward the light reception surface of the light reception portion is arranged in the housing portion forming the specific region.

  • Patent number: 9506910
    Abstract: In a urine component analysis device, a correlation storage section stores data indicating a correlation between a measured concentration in one urine and in total urine in one day for each of a first and second specific component in the urine excreted by a human. A data input section inputs data indicating a concentration of the first specific component and of the second specific component in one urine of a subject. A concentration of the first specific component and of the second specific component in total urine in one day are determined by performing conversion using the correlation stored in the correlation storage section based on the concentration of the first specific component and the second specific component in the one urine. A concentration ratio between the first specific component and the second specific component in total urine in one day is determined based on the results of conversion.

  • Patent number: 9506906
    Abstract: A urine component analysis device with a correlation storage section stores data indicating a correlation between a measured concentration of a specific component in human urine and measured concentration of the specific urine component in one day. A data input section inputs data indicating concentration of the specific component in one subject's urine. A concentration of the specific component in total urine of the subject in one day is determined by conversion using the correlation storage section based on the concentration of the specific component in the urine. A total urine amount acquirement section acquires total amount of urine excreted by the subject in one day based on conversion or database. An excretion amount of the specific component in total urine of the subject in one day is calculated by multiplying the concentration of the specific component in total urine in one day, by the acquired total urine amount.
