Abstract: The invention relates to an electric shaver (1) comprising a cutter unit (3), an electric motor (4), a load detector arranged to detect a load current of the motor (4) and a controller. The controller switches the average voltage from a first level to a second level once the load current exceeds a first threshold value (TH_TH), and switches the average voltage from the second level back to the first level if the load current falls below a second threshold value (TH_TL) and stays below the second threshold value (TH_TL) for a predefined time period. By operating on a lower energy consumption when the cutter unit of the shaver is not in contact with the skin, energy is saved without the need for a proximity sensor.

At least a part of the fluid channel (7) is elastically deformable from a closed position, in which the passage through the fluid channel (7) is closed off, to an opened position, in which the passage through the fluid channel (7) is opened by pivoting the handle (2) with respect to the treatment device (4, 24) from a rest position to an activated position, and vice versa.

Abstract: A shaver comprises a skin engaging portion and a cutting element, wherein the skin engaging portion comprises a force-generating member that can be selectively activated during use to increase or decrease a force of attraction to the skin of a user. The force-generating members may be electro-adhesive elements. A controller may be provided to selectively activate these elements.

Abstract: The sprayhead device includes a housing (60) having an orifice plate (62) therein with at least one orifice opening (64) therethrough. A liquid line (36) delivers liquid to the sprayhead, where it proceeds through the orifice opening, wherein the liquid flow rate through the orifice and the liquid pressure are sufficiently great relative to the size of the orifice that the liquid moves through the orifice as a continuous stream. Gas is delivered to the housing and gas flows to the interior of the sprayhead through at least two openings (68) in the housing. The gas streams (flows) intercept the liquid flow perpendicularly, approximately 180° apart. The velocity of the gas flows is sufficient to break up the liquid stream from the orifice into a spray of droplets of desired size and velocity, accelerating them out of an acceleration duct (66) exit portion of the housing.

Abstract: A shaving kit includes cartridge store for storing at least one spare blade cartridge and a container for storing a shaving fluid like a refreshing or cleaning lotion or a shaving foam. The container includes a volume of the shaving fluid which is sufficient for several series of shaving actions.

Abstract: The present invention relates to a skin treatment device (1, F). The device comprises a radiation source (13) in a housing, such that radiation can be emitted through an exit opening in the housing. It further comprises at least one skin presence sensor (43, 63) capable of measuring the presence of skin (7) in a number of respective positions, and a control unit (37). The control unit (37) is constructed to determine a covered portion of the exit opening (15) from a measurement signal of the skin presence sensor and to restrict emission of the radiation (13) to the covered portion of the exit opening (15), e.g. by modifying the control of a radiation beam manipulator (11), or by controlling radiation-blocking means, such as blinds, in the exit opening (15). The invention provides a more efficient and yet safe treatment device (1, 1?), since a larger exit opening (15) can be selected, while unwanted emission of radiation (13) through uncovered portions of the exit opening (15) is still prevented.

Abstract: The droplet spray teeth cleaning system includes in one aspect a window of temperature and volumetric flow ratio between air and gas for safe and comfortable yet effective operation, the volumetric flow ratio ranging between approximately 24 and 875 and the temperature from approximately 27° C. to a maximum of 60° C. The temperature is maintained by a flow-through heater (74) arranged around a liquid line portion (51) of the droplet spray system, preferably in a handle portion (52) of the system. Also included is a thermocouple heat sensor arrangement (78) which determines the temperature of the liquid prior to the nozzle portion and a control (76, 53) for maintaining the temperature within the temperature/flow ratio window. A filter (126) is provided, preferably in the head portion of the system, for filtering out particles from the liquid, while at the same time permitting adequate flow therethrough at least during the expected lifetime of the replaceable head portion of the system.

Abstract: A device (1) for supplying shaving aid (10) to cutting units (22) of an electric shaver (20) is designed as a stand-alone unit which is to be arranged separately from the shaver (20), and which is adapted to receiving the shaver (20). As a consequence of this design, this supplying device (1) may be designed such as to contain more shaving aid (10) than any supplying device that needs to be positioned inside the shaver (20), so that the need for a user to replenish the shaving aid (10) arises less frequently. The supplying device may further comprise means for performing at least one other function than supplying a shaving aid (10) to a shaver (20), for example a function of cleaning a shaving head (21) of the shaver (20) and/or a function of charging a battery of the shaver (20).

Abstract: The invention relates to a device (1) for removing hair (46) from skin (30), comprising an optical hair cutting device(12, 14, 20), and a hair and debris removing system. The hair removing system comprises a remover part (36) that mechanically engages the hair (46) in order to remove it after severing, or cutting. The use of mechanical engaging has the advantage that the optical contactless severing method, which by itself is not capable of removing hairs after cutting, is assisted in actual removing the hairs. The debris removing system may comprise a brush (36), a tape or fluid dispenser, etc., and may be assisted by a suction device (48).

Abstract: The present invention relates to a skin treatment device (1, 1?). The device comprises in a housing a source of radiation (13), that is emittable through an exit opening in the housing. It further comprises a plurality of skin presence sensors (43, 63) that are able to measure the presence of skin (7) at their respective positions, and a control unit (37). The control unit (37) is constructed to determine a covered part of the exit opening (15) from measurement signals of the skin presence sensors, and to restrict emission of the radiation (13) to the covered part of the exit opening (15), e.g. by modifying the control of a radiation beam manipulator (11), or by controlling radiation blocking means, such as blinds, in the exit opening (15). The invention provides a more efficient and yet safe treatment device (1, 1?), since a larger exit opening (15) may be selected, while unwanted emission of radiation (13) through uncovered parts of the exit opening (15) is yet prevented.
