Abstract:
To provide a technology that can suppress an operation unintended by a user caused by an erroneous operation by the user. An electrochemical sensor according to one aspect of the present invention is for measuring a concentration ratio between sodium ions and potassium ions in a liquid to be measured that includes: a sensor head; and a calculation unit that allows performing a calibration operation and a measurement operation. The calibration operation calculates a characteristic parameter of the sensor head based on sensing data of the sensor head in a state where the sensor head is brought into contact with a calibration agent. The measurement operation calculates the concentration ratio based on the characteristic parameter of the sensor head and the sensing data of the sensor head in a state where the sensor head is brought into contact with the liquid to be measured.

The searched range setting unit changes the searched frequency range based on an exercise intensity indicated by the exercise intensity signal.
Abstract:
The present invention provides an electrolyte analysis test strip for measuring a concentration of ions contained in an electrolyte. The electrolyte analysis test strip includes a substrate extending in one direction. An ion sensitive electrode is provided in specific regions on a side of one end in the one direction on a main surface of the substrate. A main extraction electrode extends from the ion sensitive electrode to a side of an other end. A solution detection electrode is provided in a proximal region in a manner separated from the main extraction electrode, and is for detecting whether or not the solution detection electrode is in contact with the electrolyte. An auxiliary extraction electrode extends from the solution detection electrode to the side of the other end in a manner separated from the main extraction electrode.
Abstract:
An electrolyte analysis device includes a substrate extending in one direction, a main base portion provided on a main surface of the substrate, an ion selective film provided to be in contact with the main base portion so as to cover the main base portion, and an auxiliary base portion provided on the substrate. In a state where the electrolyte is in contact with a side of one end of the substrate so as to cover the side of the one end, a peeling determination unit obtains a potential of the main base portion and a potential of the auxiliary base portion, respectively. Whether or not the ion selective film is peeled from the main base portion is determined based on a potential difference between an obtained potential of the main base portion and an obtained potential of the auxiliary base portion.
Abstract:
In the present invention, a blood pressure measuring cuff is worn around a rod-shaped site to be measured of a subject in a circumferential direction. A light projecting unit is disposed only along an edge portion on one side or both sides of the cuff in a width direction, and irradiates a periphery of a target region of the site to be measured with light. A light receiving unit is provided in a sheet shape along a specific portion facing the target region on an inner surface of the cuff, and receives light scattered or reflected by the target region to obtain an image including a vein pattern of the target region. An authentication unit compares the vein pattern with a reference vein pattern registered in advance, and performs the vein authentication on the subject.
Abstract:
An electric toothbrush includes a gyro sensor inside a main body. The gyro sensor detects an angular velocity of the main body and the main body includes a head portion, a neck portion, and a grip portion in a longitudinal axis direction. An angle formed by a longitudinal axis of the main body in a state that brush bristles of the head portion contact with a brushing site in a dentition with respect to the longitudinal axis of the main body in a state that the brush bristles of the head portion contact with a reference position in the dentition is obtained, based on an output from the gyro sensor. A corresponding point corresponding to the brushing site on an approximate curve that curves corresponding to the dentition is obtained based on the angle, and coordinates of the corresponding point are used as a translational position of the brushing site.
