  • Patent number: 11324307
    Abstract: A pressure feedback system continuously monitors the level of pressure or force on a brush head and is programmed to provide a feedback signal to a user based on the amount of pressure. The pressure level is monitored as a function of the change in the speed of the drive shaft. The system includes a housing, a motor, a drive shaft for attachment to a brush head, a feedback device, a sensor capable of detecting a change in the rotational speed of the drive shaft, and a microprocessor. The microprocessor is programmed activate the feedback device as a function of the measured change in rotational speed. The sensor may be a Hall effect sensor, or another sensor that is responsive to a magnetic field. A magnet may be positioned on the drive shaft, or another portion of the system that moves as a function of the drive shaft.
