Abstract: A personal care system has a personal care device including a memory unit, a display unit, a first wireless communication unit, and a separate input device comprising a second wireless communication unit arranged for wireless communication with the first wireless communication unit. The separate input device is arranged for allowing a user to provide text data or picture data or for selecting text data or picture data from a database, wherein the separate input device is arranged to wirelessly send the provided or selected text or picture data to the personal care device, which is arranged to receive the wirelessly sent data and to store that into a memory of the memory unit and to use the received data in replacement of previously stored default text data or picture data for user communication on the display unit.

Abstract: An electric toothbrush having bristle driven pulsation includes a brush head having a bristle holder and bristle tufts attached to the bristle holder. The bristle tufts and corresponding bristles are disposed at a perpendicular and/or a non-perpendicular angle with respect to a mounting surface of the brush head. The electric toothbrush also includes an electric toothbrush handle removably attached to the brush head. The electric toothbrush handle includes a linear motor configured to drive the bristle holder via a gearing structure coupled to the linear motor and the bristle holder. The linear motor causes the bristle holder to rotate clockwise and counterclockwise at a rotation frequency which exceeds a rotation frequency threshold (e.g., 100 Hz, 120 Hz, etc.). The linear motor also causes the brush head to vibrate in a direction toward and away from a contact surface in synchronization with the rotation of the bristles.

Abstract: The invention relates to a hair removal device, comprising: a handle having a motor, a cutting head having a blade unit with a first and second blade for cutting hair, said cutting head having a first snap fit connector and a comb attachment releasably attachable to the cutting head, said comb attachment having a second snap fit connector provided to engage by snap fit connection with the first snap fit connector for attaching the comb attachment at the cutting head, wherein, said first snap fit connector is at least one of: formed in a shape to flex, made of a material to flex or supported to flex, so that said first snap fit connector is able to flex when brought into engagement with said second snap fit connector.

Abstract: The invention relates to an electrically driven device, for example an electric hair removal device, such as a wet or dry shaver, an electric toothbrush or an electric skin treatment device. The electrically driven device comprises a housing having a chassis, wherein the chassis comprises an electric motor having a first drive shaft, a battery unit, and an oscillating body having a second drive shaft. A first longitudinal axis is defined arranged along the second drive shaft, a second longitudinal axis is defined arranged along the first drive shaft, and a third longitudinal axis is defined arranged through the center of the body of the battery unit, wherein the second longitudinal axis and/or the third longitudinal axis are parallel offset to the first longitudinal axis.

Abstract: The present invention relates to a cutter system for an electric shaver and/or trimmer. The cutter system includes a pair of comb-like cutting elements with cooperating toothed cutting edges and movably supported relative to each other by a support element, wherein lateral ends of at least one of the cutting elements are provided with lateral protection elements having rounded and/or chamfered edge contours for soft skin engagement. The lateral protection element is integrally formed in one part with the cutting element by an end portion of the cutting element bent away from a skin contact surface thereof and enveloping a gap movably receiving the other cutting element and/or enveloping the support element.

Abstract: The present invention relates to cutting body hair such as beard stubble. More particularly, the present invention relates to a cutter system for an electric shaver and/or trimmer, with a pair of cooperating cutting elements with at least one row of comb-like cutting teeth. The cutting elements are movably supported relative to each other by a support structure. At least one of the cutting elements, when viewed in cross section, has a C-shape including a pair of dog-eared holding flanges attached to the support structure and a slightly dome shaped or flat center section. The row of comb-like cutting teeth are formed in a transitional section between the dog-eared holding flanges and the center section. The dog-eared holding flange at the transitional section may be provided with a step-like concave depression forming thinned-out tooth tips.

Abstract: A method of gluing a metal part to another part for use in a personal care device such as an electric toothbrush. The method includes steps of providing a metal, such as steel, part, and another, metal, part; treating a surface portion of the metal part with ultra-fast laser pulses having a pulse length in the femtosecond range, e.g., from about 1 femtosecond to about 990 femtoseconds, so that a surface layer of the metal surface is removed; applying an adhesive to the treated surface of the metal part or to a surface of the other part; and gluing the metal part and the other part together.

Abstract: The present invention is concerned with a skin treatment device and an interface for, preferably detachably, attaching a brush to a skin treatment device, wherein the skin treatment device comprises a drive unit, a component part driven by the drive unit to perform a rotatory and/or oscillating movement and a hood at least partially encasing said driven component part. One of said brush and said driven component part comprises at least two protrusions which both extend through openings in the hood when the brush is attached to the skin treatment device. At least one of said protrusions engages the other of said brush and said driven component part by snap fit when the brush is attached to the skin treatment device.

Abstract: The invention relates to a swing bridge for converting a rotary motion into an oscillating motion, especially into a linear oscillating motion, especially within an electrically driven device. The swing bridge comprises an oscillating body defining a plane. The oscillating body comprises a slot arranged in the plane, wherein a first axis extends through the slot perpendicular to the plane, and a drive shaft protruding perpendicular to the plane along a second axis.
