A system for classifying the usage of a handheld consumer device having a sensor and an analyzer. The sensor determines usage data at successive time instants and provides a temporally successive sequence of usage data during a usage session. The analyzer classifies the usage of the device with respect to at least one set usage classes and assembles a temporally successive sequence of input tuples of usage data relating to a predetermined time period of the usage session, each of the input tuples having at least one element representing the usage data at the respective time instant and for inputting the sequence of input tuples into at least one artificial neural network arranged to output at least one output tuple comprising a number of elements in accordance with the number of usage classes, each element of the output tuple representing a prediction value that the usage of the consumer device at the given time instant relates to a respective usage class.

A magnetic personal guide for guiding a user through a personal care routine is adapted for releasably holding a personal care implement. The personal care implement includes a section at least partially made from a magnetic and/or ferromagnetic material. The magnetic personal guide includes: a guidance tool, the guidance tool being activated by detaching the personal care implement from the magnetic personal care guide; and an electro-chrome display providing a signal guiding the user through the personal care routine when the guidance tool is activated. A personal care guidance system for guiding a user through a personal care routine that includes such magnetic personal care guide and a personal care implement comprising a section at least partially made from a magnetic and/or ferromagnetic material.

A system for tracking and storing data associated with 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 guide to which the personal care implement is magnetically attachable and detachable, wherein the magnetic guide includes a guidance tool, the guidance tool being activated to track and store data by detaching the personal care implement from the magnetic guide.

A kit for supporting an environmentally sustainable personal care routine, the kit including: a personal care implement that includes 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 including a guidance tool, the guidance tool being activated and providing guidance on environmentally sustainable behavior by detaching the personal care implement from the magnetic personal care guide.

A kit that includes a personal care implement having a section at least partially made from a magnetic and/or ferromagnetic material, and a magnetic holder to which the personal care implement is magnetically attachable and detachable, the magnetic holder having a timer, the timer being activated by detaching the personal care implement from the magnetic holder.

An electric toothbrush and a control method thereof includes a brush head, a brush handle, a motor, a pressure responding unit, and a control unit. The motor is disposed in the brush handle, a driving shaft of the motor penetrates through the brush handle and is connected with the brush head for driving. The pressure responding unit is disposed in the brush handle, and the pressure responding unit is configured to acquire a force of the brush head. The control unit is disposed in the brush handle, and the control unit is electrically connected with the pressure responding unit and the motor.

A universal base for an electric toothbrush has a body comprising a top surface, a bottom surface, and a side surface therebetween. The base can be coupled with the toothbrush for wireless communication therebetween. The base includes a charging component for inductively charging the electric toothbrush, a Bluetooth component for communicating usage data received from the toothbrush during a brushing session, an analyzing component for instantaneous processing of the usage data received from the toothbrush, a timer-clock component for displaying either a count-up or a countdown of the brushing session during the brushing session and time of day before and after the brushing session, and a multi-functional light component for instantaneously communicating, during the brushing session, at least one element of the usage data.

An oral care system with coaching features. The oral care system may include indicator units to indicate to a user when plaque is present on the oral surfaces and to indicate to a user when it is time to move to a different area of the oral cavity for cleaning. The oral care system may include a feature whereby a user can silence the indicator function so as not to be alerted of the detection of plaque or other oral maladies during a cleaning session. The oral care system may include a light ring which surrounds a button on the handle to inform a user about the amount of time elapsed during a cleaning session.
