Abstract
The toothbrush includes a sensor system for determining pressure on the teeth by a direct force measurement such as displacement, and a system for determining pressure on the teeth by a dynamic load measurement system, such as phase shift. These different pressure results are combined with peak-to-peak bristle motion values of Hall effect output values and compared to a table to obtain a more accurate value of bristle pressure against the teeth and to raise, lower or maintain the trigger threshold of excessive pressure accordingly.
