Abstract:
A grooming appliance (100) comprising: a grooming mechanism (102) for grooming a user; a motor (104) arranged to operate the grooming mechanism; and a controller (106) configured to modulate a data signal into sound produced by the grooming appliance during the operation of the grooming mechanism by the motor, in order to transmit information relating to the grooming appliance. In embodiments, the sound being modulated is caused by the motor when operating the grooming mechanism. In this case the controller is arranged to supply a drive signal to the motor in order to control the motor, and to perform the modulation by varying the drive signal in order to modulate the data signal into the sound caused by the motor during operation of the grooming mechanism.
Abstract:
The present application relates to a device for treating skin using non-thermal plasma. It comprises a housing having a skin interface electrode for application to skin during treatment, a generator for generating non-thermal plasma at the skin interface electrode; and an isolating element to isolate a region surrounding said skin interface electrode other than during treatment so that non-thermal plasma generated at the skin interface electrode within said region sterilises the skin interface electrode.
Abstract:
The present invention relates to a personal care device having a surface intended to engage the skin and/or hair, such as a blade razor or an electric shaver. The surface of such a device is formed from a substrate on which a hard coating layer is provided. A lubricating layer comprising pendant hydrophilic polymer chains is provided on the hard coating. The hard coating has particles incorporated therein, said particles having covalently attached thereto said pendant hydrophilic polymer chains. In addition, the present invention relates to a process of making a skin engaging surface for such personal care devices.
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.
Abstract:
The present invention relates to device for treating skin using non-thermal plasma. The device comprises an electrode head assembly having an skin interface electrode for application to skin during treatment, a transformer configured to change a low voltage electrical signal into a higher voltage electrical signal, and a generator to receive said higher voltage electrical signal and generate non-thermal plasma at said skin interface electrode, and a driving device comprising a power source to generate said low voltage electrical signal. The electrode head assembly and the driving device include cooperating elements to releasably mount the electrode head assembly to the driving device and electrically connect the power source to the transformer.
Abstract:
The present disclosure relates to a method of forming a sheet-metal based double-walled stationary blade (24) for a hair cutting appliance (10), the method comprising: providing a first pre-product layer (70), providing a second pre-product layer (72) which is separate from the first pre-product layer (70), providing a guide slot (44) for a cutter (26), and bonding the first pre-product layer (70) and the second pre-product layer (72) to one another such that the pre-product layers (70, 72) are arranged to jointly receive a to-be-mounted cutter (26), wherein the first pre-product layer (70) and the second pre-product layer (72), in the bonded state, are at least partially offset from one another to provide a defined mating clearance fit for the to-be-mounted cutter (26), wherein the pre-product layers (70, 72) are bonded to one another at their longitudinal ends such that stationary blade teeth (54) are partially formed by the first pre-product layer (70) and partially formed by the second pre- product layer (72), and wherein tips (56) of the stationary blade teeth (54) are arranged adjacent to a transition zone (84) between the pre-product layers (70, 72). The present disclosure further relates to a cutting appliance and to a blade set (22) for such an appliance.
Abstract:
A shaving apparatus (1) provided with at least one cutting unit (3) comprising an external cutting member (4) and an internal cutting member (5) which is drivable relative to the external cutting member in at least one driving direction P. The internal cutting member comprises at least one cutting element (10) comprising a cutting edge (11) being movable along a cutting path (12) whilst being driven in the at least one driving direction. The external cutting member comprises at least one hair-entry aperture (8) which is bounded by at least a first and a second wall portion of the external cutting member, at least the first wall portion (13) comprising a cutting edge A for cooperation with the cutting edge of the internal cutting member. An edge portion of the second wall portion (44, 54) facing a plane comprising the cutting path, in a cross section taken substantially perpendicularly to the plane (22) comprising the cutting path, touches a virtual circle (58) with a radius of at least (30) micrometer at at least two contact points (59, 60) on the virtual circle, and wherein the tangents at two successive contact points where the edge portion touches the virtual circle, enclose an angle of at least 150 degrees.
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.
