  • Personal Care System and Method
    Publication number: 20230255737
    Abstract: In one embodiment, a personal care appliance includes an electric motor having a drive shaft. In response to a voltage signal, the drive shaft is oscillated in an oscillatory motion having an oscillation amplitude. A control circuit includes, in operable cooperation, a user interface, a processor, a pulse width modulation signal generator, and a power source. The control circuit supplies the voltage signal to the electric motor, the voltage signal having a frequency and a duty cycle. The control circuit varies the frequency and the duty cycle of the voltage signal in response to an oscillation adjustment input received from the user interface so that the oscillation amplitude of the drive shaft is varied along a substantially linear rate of change profile relative to the frequency.
