  • the present disclosure is directed generally to methods and systems for identifying or characterizing the head member of a personal care device.
  • some electric personal care devices enable use by more than one member of a household. Accordingly, in addition to identifying brush head type, it is also desirable to identify the user and user profile of the individual using a head member. For example, when a family shares a single handle but uses different head members, it is challenging to identify each head member. Currently the only way to identify a head member is to add a visual label to the head member, such as using a diamond shape for one member and a circle for another. Also, if the different users have different settings for the personal care device, they will have to change the settings manually each time they switch the head member. Similarly, if the personal care device does not know which head member is being used, it cannot track how long the head member has been used in total, and thus it cannot automatically remind a user to replace the head member at the appropriate time.
