摘要： An electrocardiographic waveform measurement device includes a plurality of electrodes configured to measure an electrocardiographic waveform of a measurement target, a vibration detection unit configured to approach a chest region of the measurement target to detect vibration based on a beat of a heart of the measurement target, and a control unit configured to execute measurement processing for the electrocardiographic waveform. The control unit further executes lead type determination processing for determining, based on a detection result from the vibration detection unit, at least whether the electrocardiographic waveform measured by the measurement processing is an electrocardiographic waveform obtained by chest lead measurement.

摘要： An electric toothbrush includes a stem member on which a replaceable toothbrush is mounted. The stem member is made of synthetic resin and has a cavity for accommodating a DC motor and a vibration shaft connected to the DC motor. One end of the cavity is opened for inserting the DC motor and the vibration shaft together, and the other end thereof is closed. A free end of the vibration shaft is rotatably supported at the closed end of the cavity. The cavity has a cone-shaped wall so that the DC motor is firmly held in the cavity by a rigid contact between a shoulder portion of the DC motor and the cone-shaped wall.

摘要： The plaque detecting device of the present invention comprises a light emitting unit (450) which irradiates ultraviolet or blue excitation light (L) toward the tooth surface (99a), and a first and second light receiving units (402) which receive radiated light (L′) from the tooth surface (99a). The first light receiving unit extracts the spectral component of a first wavelength region including the wavelength range of fluorescent light specific to plaque from the radiated light (L′), and obtains a first output value corresponding to the intensity of that spectral component. The second light receiving unit extracts, from the radiated light (L′), the spectral component of a second wavelength region containing the wavelength range of the fluorescent light specific to enamel and having a predetermined lower limit wavelength below the lower limit wavelength of the first wavelength region, and obtains a second output value corresponding to the intensity of this spectral component. Determination of the relative magnitude of the ratio between the first output value and the second output value as compared to a first threshold value is performed. Determination of the relative magnitude of the difference between the first output value and the second output value as compared to a second threshold value is performed.

摘要： A biological information measurement device that performs sound wave communications with an external terminal including a microphone includes a housing; a measurement circuit that measures biological information; a modulation circuit that converts the biological information measured into a sound wave signal; and a vibration member that vibrates based on the sound wave signal transmitted from the modulation circuit. The measurement circuit, the modulation circuit and the vibration member are provided inside the housing. The housing includes a terminal placement surface on which the terminal is placed. The vibration member and the terminal placement surface are in contact with each other so that vibration of the vibration member is transmitted to the terminal placement surface.

摘要： 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.
