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.

An electric razor comprises a head, a grip, a blade unit disposed in the head for cutting hair, a skin electrode disposed in the head, and a grip electrode disposed in the grip. The electric razor further comprises a voltage application circuit for applying a voltage between the skin electrode and the grip electrode to cause a current to flow between the skin electrode and the grip electrode through a human body, and a controller that controls the voltage application circuit.

A beauty instrument according to the present disclosure comprises a skin electrode disposed in a head, a grip electrode disposed in a grip, a voltage application circuit for applying a voltage between the skin electrode and the grip electrode to cause a current to flow between the skin electrode and the grip electrode through a human body, and a controller that controls the voltage application circuit. The controller comprises a touch detector that detects touch of a skin surface of the human body with the skin electrode. Before the touch detector detects the touch, the voltage application circuit is controlled to apply a first voltage having a relatively high frequency, and after the touch detector detects the touch, the voltage application circuit is controlled to apply a second voltage having a relatively low frequency.

A hair cutting device (10) is provided comprising a cutter unit (11), a skin stretcher (12) and slit adapting means. The cutter unit (11) comprises a skin-contact surface for dragging over a skin surface (21) in a shaving direction (55), a front surface arranged in front of the skin-contact surface in the shaving direction (55), and a laser beam exit window arranged in the front surface for allowing a hair cutting laser beam (13) to cut a hair (22) near the skin surface (21) in front of the front surface. The skin stretcher (12) is positioned in front of the cutter unit (11), according to the shaving direction (55), and comprises a stretcher surface for dragging over the skin surface (21) together with the skin-contact surface, such that a skin dome (23) is formed by the skin surface (21) in a slit between the skin stretcher (12) and the cutter unit (11). The slit adapting means are provided for adapting at least one dimension (51, 52, 54) of the slit for controlling a shape of the skin dome (23).

A smart shaving system with a three-dimension (3D) camera assists the user of a shaving razor. The 3D camera is communicatively connected to the shaving razor and to a razor cartridge vendor platform via an Internet-of-Things (IoT) gateway. The 3D camera can be incorporated into the shaving razor. The razor has hardware/software capabilities to function as a stand-alone Internet-of-Things (IoT) device. The 3D camera can assist the user to determine whether a particular skin surface area has been adequately shaved, and/or (ii) assist the user regarding the type of shaving cartridge and/or razor suited for the particular user's physical characteristics (e.g., skin and/or hair).

The present application relates to a device for cutting hair. The device comprises a housing, a cutting unit arranged at one end of said housing and comprising a cutting element. The device comprises an electrode, and a voltage source connected to the electrode. The voltage source is configured to provide the electrode with an electrostatic charge so that the electrode is configured to attract charges naturally present in haircut by the cutting unit without actively charging the cut hair and to consequently draw and/or hold the cut hair away from the cutting element. The hair cutting device also having a sensor which is arranged to detect a condition relating to the use of the device. The voltage source is activated or deactivated depending on said detected condition.
