Abstract
A method for controlling overpressure in an electric oral-care implement having a treatment head with at least one functional element driven by a motor. The method includes detecting a stimulus to energize the motor, setting a baseline current, and repeatedly execute an overpressure-detection control loop, said loop including measuring the motor's instantaneous current draw, adding an increment value to the baseline current or subtracting 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 performing a corrective action in response to the detected occurrence of overpressure.
