    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.

    Abstract: An ultrasonic system may include: an oral care device including: a head; a plurality of teeth cleaning elements extending from a first side of the head; and an ultrasound module including an ultrasound transceiver positioned in the head, the ultrasound transceiver configured to produce an ultrasound signal on the first side of the head and to generate a detection signal from a reflected ultrasound signal; and a processing module operably coupled to the ultrasound module to receive the detection signal; wherein the processing module includes a programmable processor configured to process the detection signal non-linearly with respect to time by first identifying a first reflection representing a surface of a tooth and then determining whether a second reflection peak is present in the detection signal at a time prior to the first reflection peak, the second reflection peak representing a biofilm on the surface of the tooth.
