In one embodiment, the present disclosure is directed to a method for providing a personal toothbrushing challenge via an application of an electronic device. A user interface displays to a user of an electronic device, via a user interface, challenge parameters for creating a personal toothbrushing challenge, the challenge parameters including a type of challenge and a challenge period. The user interface receives from the user a parameter selection for each of the challenge parameters, each combination of parameter selections having a corresponding brushing expectation and point value. The electronic device receives brushing data from a user toothbrush indicative of user brushing activity, and determines, based on the brushing data, whether the user satisfied the brushing expectation corresponding with the combination of parameter selections. Upon determining that the user satisfied the brushing expectation, the user interface displays that the corresponding point value has been awarded to the user.

An oral care implement (1) comprising: an electrode pair with an impedance formed therebetween when electrified; a frequency generator, electrically connected to the electrode pair, for applying a voltage with at least two different frequencies between the electrode pair; an impedance measurement unit, electrically coupled to the electrode pair, for measuring impedance values between the electrode pair at least at the different frequencies; and a contact determination unit, in communication with the impedance measurement unit, wherein the contact determination unit comprises a memory for storing a function, wherein the function correlates impedance values of a defined oral area at the different frequencies, and wherein the contact determination unit comprises a processor for processing the measured impedance values to the stored function so as to determine contact information of the electrode pair with the defined oral area.

A personal care system having a treatment device for applying a treatment to the skin or hair of a user is provided. The treatment device has a camera for taking an image of the skin. The system may include or be in communication with an application programming interface (API) that can process the image. The system or an associated API can recommend the use of treatment regimens or topical products according to information determined from the digital image of the skin.

An oral care system that includes an oral care implement and a tracking attachment. The oral care implement may include a handle and a head. The tracking attachment is detachably coupled to the oral care implement. The tracking attachment may include an outer casing having an outer surface and a connection element that is configured to mate with a connection element on a handle of the powered oral care implement to couple the outer casing to the handle. The tracking attachment may further include a plurality of visual markers protruding from the outer surface of the outer casing.

A toothbrush that includes a piezochromic polymer or a proximity dye based polymer effective to emit an optical signal indicative of brushing force.

Tooth brushing monitoring system is disclosed that includes a toothbrush with sensors and a base station. The sensors record data regarding the quality, quantity and location of brushing and the system can analyze the data to provide feedback on the quality of brushing. This feedback provides motivation for users to increase their brushing habits, leading to a decrease in plaque, tooth decay and gingivitis.

A personal care guidance system for guiding a user through a personal care routine, the system including a personal care implement having a section at least partially made from a magnetic and/or ferromagnetic material, and a magnetic personal care guide to which the personal care implement is magnetically attachable and detachable. The magnetic personal care guide includes a guidance tool, the guidance tool being activated by detaching the personal care implement from the magnetic personal care guide.

Electric toothbrush (1) comprising an electric motor as well as a brushing organ (3) of the teeth connected to said electric motor to be rotated by the latter, said electric toothbrush (1) being characterized in that it comprises a device for measuring an electrical quantity representative of a contact pressure between the brushing organ (3) and the teeth, as well as a processing unit connected to said measurement device to emit a first warning signal when the value of said electrical quantity measured by said measurement device is greater than a predetermined threshold.

Oral hygiene instruments.

An apparatus for performing a localization of a movable treatment device having at least one inertial sensor and configured to treat the target surface. The apparatus has a motion pattern classification device configured to discriminate between two or more motion classes contained in a set of motion classes, and an interface for providing, from the inertial sensor to the motion pattern classification device, inertial sensor data representing a movement of the movable treatment device. The motion pattern classification device has a neural network configured to receive and classify inertial sensor data with respect to the motion classes associated with one or more different zones relating to the target surface so that the classification of inertial sensor data indicates an estimation of the location of the movable treatment device with respect to the one or more zones of the target surface.
