  • Patent number: 10869741
    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.

  • Patent number: 8613532
    Abstract: In the light flux controlling member (5), the angle between an optical path of light output from the light emission center (14) of a light emitting element (4) and optical axis L1 is ?2. Light is incident on the light flux controlling member (5) through an input surface and travels inside the light flux controlling member at an angle ?2 with respect to optical axis L1. Then, light is output from a light control output surface (10) at an angle ?3 with respect to optical axis L1. The input surface (15) and the light control output surface (10) are formed such that, in a range 0<?1??1max, the relationship between ?1 and ?2 is reversed from ?1<?2 to ?1>?2 when ?1 increases, and the relationship between ?1 and ?3 is reversed from ?1<?3 to ?1>?3 when ?1 increases.
