ABSTRACT:
A system and a method for a controllable power-assisted application of pressure includes a force sensor capable of sensing a user-applied force; and a force generator responsive to the sensed user-applied force and capable of generating a force that is applied to a pressure-applying device. A force magnitude of the force applied to the pressure-applying device is based on a magnitude of the sensed user-applied force. One embodiment provides that the force applied to the pressure-applying device by the force generator exerts a predetermined amount of pressure against a surface. Another embodiment provides that the force magnitude is greater than a magnitude of the sensed user-applied force. Yet another embodiment provides that the force magnitude is proportional to a magnitude of the sensed user-applied force.
