Abstract
The toothbrush includes a handle portion which includes a power drive system () and further includes a brushhead assembly (), which includes a brushhead arm having a brush element () at a distal end thereof A drive train assembly () is responsive to a drive signal from the power assembly for converting the action of the power assembly to a motion of the brushhead assembly. A magnet () is secured to the rear of the drive train, with a Hall effect sensor () mounted within the magnetic field produced by the magnet as the toothbrush moves in operation. Pressure on the brush element produces a phase shift of the Hall sensor output. A processor () determines the value of the phase shift of the Hall sensor signal as pressure is applied to the brush member and produces a signal indicative of the pressure applied by using stored information () which relates phase shift to pressure for the particular appliance.
