An electric grooming appliance includes a housing, a grooming device, an electric motor, and a controller. In some embodiments, the electric grooming appliance is capable of operating in different modes and includes a user interface which allows a user to communicate with the controller and select at least one of the modes. The electric grooming appliance may provide information to the user relating to information determined and/or detected during a grooming session. In addition, the electric grooming appliance may record or store grooming session information on a memory and estimate future operating parameters based on the grooming session information. The electric grooming appliance may include a trimmer assembly that is positionable between a stowed position and an operative position.

System and method for improving the shaving experience by providing improved visibility of the skin shaving area. A digital camera is integrated with the electric shaver for close image capturing of shaving area, and displaying it on a display unit. The display unit can be integral part of the electric shaver casing, or housed in a separated device which receives the image via a communication channel. The communication channel can be wireless (using radio, audio or light) or wired, such as dedicated cabling or using powerline communication. A light source is used to better illuminate the shaving area. Video compression and digital image processing techniques are used for providing for improved shaving results. The wired communication medium can simultaneously be used also for carrying power from the electric shaver assembly to the display unit, or from the display unit to the electric shaver.

A shaving apparatus (1) having a first shaving unit portion (7) connected to a main housing (2) and accommodating a single driven input member (9) rotatable about an axis of rotation. A second shaving unit portion (8) of the shaving apparatus has a hair-cutting unit (12) and a drive unit (13) which transmits a driving force from the single driven input member to an internal cutting member (19) of the hair-cutting unit. The second shaving unit portion is manually rotatable relative to the first shaving unit portion about the axis of rotation of the single driven input member. An adjustment system (24) has a sensing unit (28, 29) configured to have an output property which varies with the angular position of the second shaving unit portion relative to the first shaving unit portion about the rotational axis. The adjustment system adjusts an operational parameter of the shaving apparatus in dependence on the output property of the sensing unit.

The present invention relates to a personal care device, in particular hair removal device such as an electric shaver, comprising an elongated handle for manually moving the personal care device along a body surface, a working head attached to said handle for effecting a personal care treatment to said body surface, said working head being movably supported relative to said handle and/or including a working head element being movably supported relative to a working head basis to allow adaption of the working head and/or of the working head element to the body surface contour, wherein an adjustment device is provided for adjusting a movability characteristic of a suspension of said working head and/or of said working head element, wherein said adjustment device includes at least one actuator for adjusting at least one characteristic.

The present invention relates to a personal care device, in particular hair removal device such as an electric shaver, comprising an elongated handle for manually moving the personal care device in short and/or long strokes along a body surface, a working head attached to said handle for effecting a personal care treatment to said body surface, and a determination unit including at least one sensor for determining stroke length to differentiate between short and long strokes, wherein said determination unit is configured to determine velocity of the working head and/or the handle, to determine beginning and end points of strokes when the determined velocity gets zero and/or changes signs, and to determine stroke length from the distance between pairs of beginning and end points next to each other.

The present invention relates to a hair removal device, such as an electric shaver or epilator, comprising a hair cutting unit, a motor for driving the hair cutting unit, a measurement unit for measuring motor current and/or induced voltage and a cutting activity determinator for determining cutting activity from the half cycles of the signal of said measurement unit, wherein a wear determination unit is provided for determining wear of the hair cutting unit from the cutting activity signal of said cutting activity determinator.

A computer-implemented method of determining a location of a personal care device with respect to a skin surface of a subject, the personal care device being configured to perform a personal care treatment to the skin when in contact with the skin surface. The method includes receiving data representative of a measured degree of curvature of the skin surface within a first region of the skin surface of the subject, with which the personal care device is in contact; determining, by comparing the measured degree of curvature with curvature information for a plurality of regions of the skin surface of the subject contained in a database, an indication of a location of the first region of the skin surface on the subject; and performing, based on the determined indication of the location of the first region, an action in respect of the personal care device. A processing apparatus, a system, a personal care device, and a computer program product are also disclosed.

A hair-cutting unit (4) for use in a hair-cutting appliance comprises an external cutting member (5) having hair-entry openings in a cutting track surface (58), an internal cutting member (6) having at least one hair-cutting element and being movable with respect to the external cutting member (5), and a skin-supporting structure (7) having a skin-supporting surface (71) for contacting a portion of skin to be subjected to a hair-cutting action. The external cutting member (5) is displaceable relative to the skin-supporting structure (7), and the hair-cutting unit (4) further comprises a safety mechanism which is designed to enable stepped and instantaneous variation between at least two discrete stages of a level (l.sub.c) of the cutting track surface (58) with respect to a level (l.sub.s) of the skin-supporting surface (71), in relation to pressure exerted by the external cutting member (5) on the skin.
