The amplitude of movement of the toothbrush workpiece is determined from the measured stator current.

To enable the brush to be moved within the body of mascara (16) in the tube, a mechanism is provided which produces movement of the brush relative to the mascara-containing tube, before the cap is released from the tube.

Force: Determines how strongly a movement of the brush affects the objects on the screen.

The system changes frequency of the toothbrush to adjust the amplitude of motion of the brush portion of the toothbrush.

The power toothbrush automatically generates motion of the brush head that simulates the "Modified Bass Method" of brushing.

This motion is transmitted to the rod of the toothbrush.

An orbital brush (100) for an orbital floor brush machine is provided according to an embodiment of the invention.

The first brush (102a, 202a) and the second brush (102b, 202b) are engaged with the movement guidance plate (122, 222).

A motorized brush (10) imparts vibrational motion to a scrubbing brush head (300).

The brushhead includes a brushhead member which includes a bristle field, the brushhead member being adapted for cleaning teeth as part of a power toothbrush, wherein the brushhead in operation moves in a reciprocating action.

This axial motion causes a reciprocating motion of a toothed rack, which sets the bristle tufts of the toothbrush rotating.

The invention relates to a brush unit which is designed for use with a toothbrush provided with an electric drive serving to oscillate the brush unit in relation to an axis of movement (43).

The brush mover has another power transmitter for transmitting the power of the motor to the rotary brush by converting it into the back-and-forth movement of the rotary brush.

The present device provides a brush which uses an orbital motion to thereby better preserve the anatomy of the crown.

One embodiment provides automatic inward movement of the brush (159) and its mounting upon break-back.
