Abstract: An electric toothbrush that detects plaque on the teeth, ensures accurate plaque detection, and performs cleaning of plaque. The electric toothbrush may include a body having a gripping part and a stem with a brush unit detachably coupled to the body. The electric toothbrush may include a light emitting element for emitting light onto the tooth and a light receiving element for receiving light that reflects off of the tooth. A controller may be included to determine an amount of plaque on the tooth based on the amount of reflected light detected. The electric toothbrush may also include a fluid dispensing system that dispenses fluid based on the amount of reflected light detected. In some aspects, the electric toothbrush may operate in multiple oscillation modes, and it may only dispense fluid in some of the modes but not all of the modes.

Abstract: An oral care implement body to which a replacement head can be detachably coupled. In one embodiment, the oral care implement body includes a gripping portion having a shoulder, a stem extending from the shoulder along a longitudinal axis, and a boss protruding from an outer surface of the stem. The boss may have a locking rib section having an undercut surface that is axially spaced from the shoulder and a positioning rib section extending from the locking rib section to the shoulder. The undercut surface may circumferentially protrude from a first side surface of the positioning rib section. The locking rib section may extend along a first rib axis and the positioning rib section may extend along a second rib axis, the first rib axis oriented obliquely to the second rib axis.

Abstract: When the present time of a clock circuit is a medication time recorded in advance in a SD card, a notice that the medication time has come is given by a voice output portion or the like. Presence/absence of a medicine package in each block of a medicine package case is sensed by a medicine package sensor. The time point and the presence/absence of the medicine package are recorded in the SD card. A notice corresponding to the presence/absence is output. At a time except for the medication time, taking-out of the case, opening/closing of the cover, taking-out and return of the medicine package are recorded in the SD card based on detection signals from the medicine package sensor, medicine package case sensor, and case cover opening/closing sensor. A notice corresponding to the sensed situation is output.

Abstract: An electric toothbrush capable of suppressing loss of vibration energy while suppressing the vibration of the portion a user grips with hand is provided. In an electric toothbrush including an inner case, made up of an inner case main body and a motor holder, mounted with various components including a motor; an outer case which interiorly accommodates the inner case and which acts as a portion the user grips with hand when brushing teeth; an eccentric shaft, configured by a shaft main body and an eccentric member, which center of gravity is arranged at a position shifted from a shaft center and which rotates by a drive force of the motor; and a vibration transmitting component for transmitting the vibration generated with the rotation of the eccentric shaft to a brush portion; where the vibration transmitting component is positioned with respect to the outer case by point contacting the inner wall surface of the outer case at a plurality of locations.

Abstract: A portable electrocardiograph (1A) includes a body unit (100) arranged with a negative electrode and a detachable unit (110) arranged with a positive electrode, where the detachable unit (110) is detachably attached to the body unit (100). The negative electrode and the positive electrode are both exposed in a state where the detachable unit (110) is united to the body unit (100). In the portable electrocardiograph (1A), an electrocardiographic waveform can be measured both in a state where the detachable unit (110) is united to the body unit (100) and in a state where the detachable unit (110) is separated from the body unit (100). According to such a configuration, it is possible to obtain the portable electrocardiograph in which a degree of freedom in measuring position is enhanced such that the electrocardiographic waveform can be measured by selecting a specific measuring position from a plurality of measuring positions according to a situation.

Abstract: In a portable electrocardiograph (100), including a negative electrode (121) to be contacted by a hand of a subject and a positive electrode (122) to be contacted to a predetermined measurement site of a subject, for measuring an electric signal detected by the negative electrode (121) and the positive electrode (122) as an electrocardiographic waveform, springs (190a, 190b, 190c, 190d) for supporting the positive electrode (122) in a freely oscillating manner are arranged in a body unit (110) including the negative electrode (121) and a processing circuit for measurement. Thus, a portable electrocardiograph that excels in handleability and that enhances the contacting stability between the electrode and the measurement site can be achieved.

Abstract: A breathing exerciser includes: a guide unit for guiding an exercise pattern of breathing to a user; a breathing sensor for detecting breathing of the user; a breathing index calculating unit for calculating, based on a signal from the breathing sensor, a breathing index at least one of before and after an exercise period during which the exercise pattern is guided, the breathing index representing a characteristic of a breathing state of the user; and an outcome index calculating unit for calculating an outcome index based on at least two breathing indices, the outcome index representing an outcome of breathing exercise; and an informing unit for informing the outcome index to the user.
