Abstract
An oral-care implement has a handle containing an electric battery and a motor. The motor's shaft is connected to a motion transmitter to drive a treatment head having at least one functional element. The implement has a pressure-control system including a microcontroller configured to detect a stimulus to energize the motor, set a baseline current, and repeatedly execute an overpressure-detection control loop comprising: measuring an instantaneous current draw, adding an increment value to or subtract a decrement value from the baseline current, thereby generating a dynamically adjusted baseline current, determining whether a difference between the instantaneous current draw and the dynamically adjusted baseline current exceeds a threshold, thereby detecting an occurrence of overpressure, and causing the implement to perform a corrective action in response to the detected overpressure.
