METHODS AND SYSTEMS FOR DETERMINATION OF CHARACTERISTICS OF USER OF PERSONAL HYGIENE DEVICE Russian patent published in 2022 - IPC A61C17/22 

FIELD: personal hygiene.

SUBSTANCE: group of inventions relates to methods and systems for identification or determination of characteristics of a user of a personal hygiene device. A device for the implementation of a method is proposed, wherein the device contains: a sensor made with the possibility of reception of sensor data relatively to personal hygiene sessions, and a controller containing a training module, a classifier, and a dimension reduction module made with the possibility of reduction in a quantitative indicator of characteristic features extracted as a result of one or more personal hygiene sessions before the identification stage, and with the possibility of reduction in a quantitative indicator of characteristic features extracted as a result of a new personal hygiene session before the identification stage. At the same time, the training module is made with the possibility of: reception from the sensor of sensor data relatively to at least one personal hygiene session for each of at least two different users of the personal hygiene device, extraction of characteristic features as a result of each of personal hygiene sessions by means of a processor extraction module, and training of the classifier for identification of a characteristic of each of at least two different users of the personal hygiene device, using extracted characteristic features. Moreover, the controller is also made with the possibility of reception from the sensor of sensor data relatively to at least part of the new personal hygiene session initiated by one of at least two different users of the personal hygiene device, and extraction of characteristic features from sensor data relatively to the new personal hygiene session, and the classifier is made with the possibility of identification of a characteristic of a user of the personal hygiene device, using characteristic features extracted as a result of the new personal hygiene session.

EFFECT: group of inventions provides for a possibility of identification of a user of a personal hygiene device without the need for an external user identifier.
