METHOD AND CONTROLLER FOR DETERMINING LOCATION OF CLEANING DEVICE IN USER'S ORAL CAVITY, DEVICE AND SYSTEM FOR CLEANING ORAL CAVITY, AS WELL AS DEVICE FOR RECEIVING INFORMATION Russian patent published in 2020 - IPC A61C17/22 A46B15/00 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medicine, specifically to a system and an oral cleaning device, a method for locating an oral cleaning device in an oral cavity of a user, device for receiving information of spatial sensors from motion identifier contained in device for cleaning of oral cavity. In the method for determining the location of a device for cleaning the oral cavity in the user's mouth processor evaluates probability of first location of device for cleaning oral cavity in user's mouth based on information of sensors received from motion identifier. Information is received from the motion identifier relating to the completed transition into the second state in the user's mouth. Completed transition is compared with a given set of possible transitions between each possible state in the user's mouth to determine the transition probability. Method includes determining, using probabilistic graphic model, containing probability of first location and probability of transition, probability of location of second state. Device for cleaning oral cavity comprises motion identifier and controller. Device for receiving information of spatial sensors from a motion identifier comprises a processor which determines the location of the device for cleaning the oral cavity in the oral cavity of the user. Oral cleaning system comprises an oral cleaning device and a device for receiving spatial sensor information from a motion identifier communicating with an oral cleaning device.

EFFECT: tracking movement of the oral cleaning device using the input of the spatial sensor, which improves the technique of cleaning teeth and helps to ensure long-term dental health.
