The invention relates to a shaving device for skin hairs. The device comprises a skin-contacting surface structure (14, 15), a cutter (6) for cutting hairs in a hair-cutting area (16), a shape-changing smart material (7), and a controller for controlling activation of the shape-changing smart material during use of the shaving device. The shape-changing smart material is configured, arranged and effective to adapt the relative position and/or relative orientation between at least part of the skin-contacting surface structure (14) and at least part of the hair-cutting area (16).

A device (100A) for treating skin (S) comprises a skin treatment member, a skin contacting surface (10), a mounting member (104) for mounting the skin treatment member (110) and the skin contacting surface (107), and friction controlling means (124, 126, 134) configured and arranged to control friction between the skin contacting surface (107) and the skin (S) to be treated, in at least one controlled friction area (122) of the skin contacting surface (107), during use when the skin contacting surface (107) is moved over the skin (S). In particular, the friction controlling means (124, 126, 134) are adapted to introduce a slip motion of the controlled friction area (122) relative to the mounting member (104) in a direction corresponding to a local direction of extension of the skin contacting surface (107). The device comprises sensing means (130, 138) configured and arranged for detecting a first parameter, which is related to an amount of friction between the skin contacting surface (107) and the skin during use, and the friction controlling means are adapted to control a second parameter of the slip motion in dependence on a value of the first parameter detected by the sensing means (130, 138). The first parameter is for example an actual motion direction of the device relative to the skin during use, or an amount of skin doming of the skin in a hair-entry aperture of the skin treatment member. The second parameter is for example a frequency or a maximum velocity of the slip motion.

An electric shaver having a shaving unit (3) and a sensor (15) with a first sensor unit (16) fixed to a main body (2; 202; 302) and a second sensor unit (17) fixed to a sensor unit carrier (22; 222; 322), for indicating a distance between the sensor units (16, 17). The shaving unit (3) and the sensor unit carrier (22; 222; 322) are suspended to the main body (2; 202; 302) for displacement along a z-axis between a rest position (22) and a pushed-in position (22′) in response to a pushing force exerted onto a shaving face (11) of the shaver (1). The first and second sensor units (16, 17) are located in positions offset from the z-axis over a distance (d) in an x-direction. An anti-tilting guide (24-27; 124; 224, 226; 326, 328) is provided for guiding the sensor unit carrier (22; 222; 322) against tilting about a y-axis.

A positioning device includes a frame having at least a front frame and one or more side frames; and a plurality of positioning interfaces, the positioning interfaces configured to at least one of transmit signals and receive signals, the signals being configured to at least partially determine at least one of position and orientation of a hair cutting device, the plurality of positioning interfaces positioned at various intervals about the frame. The front frame includes at least one structural feature designed to contact at least one feature of a user's face, and the front frame extends at least partially across said user's face.

A hand held personal care device (1) with an operative unit (3) connected to a main housing (2), a light source (24), and an optically transparent light guide (23) having a light receiving surface (27), a light emitting surface (6) and a light guiding member (31) extending from the light receiving surface to the light emitting surface for guiding light from the light receiving surface to the light emitting surface. The light source is arranged in a watertight chamber (51) of the main housing. The main housing includes an optically transparent wall portion (52) arranged adjacent to the light source and bounding the watertight chamber. The light guide is arranged outside the watertight chamber and the light receiving surface is arranged adjacent to the optically transparent wall portion in a position for receiving light from the light source via the optically transparent wall portion.

There is provided a personal care apparatus that is configured to connect to a display apparatus. The personal care apparatus comprises a first control unit configured to: determine a current operation mode of the personal care apparatus as a usage mode or a control mode, and detect a first predetermined user maneuver. The first predetermined user maneuver corresponds to a control operation of the personal care apparatus in the usage mode and corresponds to a control operation of the display apparatus in control mode. When the first predetermined user maneuver is detected, the first control unit is further configured to: perform the control operation of the personal care apparatus if the determined current operation mode is the usage mode, or transmit a control signal corresponding to the control operation of the display apparatus to the display apparatus if the determined current operation mode is the control mode.

A personal appliance. The personal appliance includes a handle having an implement connecting structure. An implement is connected to the implement connecting structure. An implement displacement sensor is associated with the handle. The implement displacement sensor measures a displacement of the implement relative to a fixed position of the handle. A power source, an acceleration sensor and an angular velocity sensor are associated with the handle.

A pivot motor for a hair clipper is provided, including a stator with a plurality of laminations, a bobbin located in operational relation to the stator and having a coil of wire wound around the bobbin, an armature being configured for driving a hair clipper moving blade at one end, and having at least one magnet at an opposite end, the armature having a pivot point, and the motor being configured for operation between 2.5 and 4.2 Volts

There is provided an apparatus (100) for determining a location of a personal care device on a user. The apparatus (100) comprises a processor (102) configured to detect a location of one or more parts of the body of a user, detect motions of at least one of the parts of the body of the user induced by the personal care device when the personal care device is in use and determine the location of the personal care device on the user based on the detected motions of the at least one part of the body of the user in relation to the detected location of the at least one part of the body of the user. The processor (102) is configured to acquire images of the user from an imaging sensor (108) directed at the user, and detect the location of the one or more parts of the body of a user and the motions of the at least one part of the body of the user induced by the personal care device from the acquired images of the user.

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.
