TOOTHBRUSH WITH POSITION TRACKING Russian patent published in 2015 - IPC A46B15/00 

FIELD: personal appliances.

SUBSTANCE: tooth brush comprises a handle section (12 or 55) and a brush head section (14 or 57) with a set (20 or 53) of bristles on one end of the tooth brush. At least one sensor (16 or 56) is mounted either on a handle, or on a carrier plate (54) for the set of bristles. If the sensor is mounted on the handle, the head position is determined by a processor (44 or 58) in relation to inner or outer dental surfaces following the temperature detected by the sensor, as both an ambient temperature, and a user's skin temperature. If the sensor is mounted on the carrier plate for the set of bristles, this procedure is performed on the basis of the position of the set of bristles in relation to user's cheek.

EFFECT: structural improvement.
