This disclosure is concerned with a personal care device with a treatment head being pivot-mounted around a pivot axis, the personal care device having a pin having a pin head, a cam element having a cam surface, a spring element biasing the pin head and the cam surface against each other, wherein the cam surface is shaped such that it defines a rest position at which the biasing spring force provided by the spring element with which the pin head and the cam surface are pushed against each other has a non-zero minimum value, and wherein a pivoting of the head around the pivot axis causes the pin head to move along the cam surface and the cam surface is further shaped such that the spring force pushing the pin head and the cam surface against each other increases with increasing pivoting angle.

An electric shaver, including a machine body and a cutting head that are connected to one another; the machine body includes an outer casing, a control chip and a driving component which are provided within the outer casing, and a handle sensing element which is provided on the outer casing; the cutting head includes a head portion sensing element; the control chip is simultaneously connected to the driving component, handle sensing element and head portion sensing element; and the driving component is also connected to the cutting head. The electric shaver will automatically start up when both the handle sensing element and the head portion sensing element sense the proximity of a human body (skin). Provided also are a corresponding handheld household electrical appliance, an electric shaver system, and a control method.

A personal care appliance with a flexible circuit board having a first end portion, a second end portion and a flexible bridge between the first end portion and the second end portion. A first rigid circuit board is mounted to the first end portion of the flexible circuit board. A second rigid circuit board is mounted to the second end portion of the flexible circuit board and folded over the first rigid circuit board. At least one electronic component that emits electromagnetic waves is mounted to the first rigid circuit board. A flexible antenna is in electrical communication with first rigid circuit board. The flexible antenna has a top surface with a copper track facing away from the first rigid circuit board in a folded position.

A method for the production of a metal strip is provided. The method includes providing an amorphous metal strip having a first main surface and a second, opposing main surface. The first and/or the second main surface are treated with a wet-chemical etching process and/or a photochemical etching process.

A wireless electric hair clipper system used to trim hair is disclosed. The wireless electric hair clipper system allows for viewing an area of hair from front, lateral and back while cutting the hair. The system includes a handheld electric hair clipper with a foldable wireless video camera providing a standardized, optimal viewing angle and a display unit including a wireless video monitor. The display unit works in conjunction with a wireless video camera to provide a series of simultaneous images and live monitoring options of the area where hair is being cut.

Surgical clipper blade assemblies with hydrophobic coating layers and methods of use for hair removal from a skin area include using a surgical clipper blade assembly including a blade, a top surface, a bottom surface, a plurality of sidewalls disposed and extending between the top surface and the bottom surface, and an aperture configured to receive the blade, and a hydrophobic coating layer disposed on at least a portion of a top skin facing surface comprising the top surface and the blade. The surgical clipper blade assembly may include a plurality of ribs on the top surface, and the portion of the top skin facing surface may include the top surface, the blade, the plurality of ribs, or combinations thereof. During operation of the blade to remove hair from the skin area, the hydrophobic coating layer reduces friction forces and prevents risk of skin abrasions.

A shaver includes a housing including first and second housing halves defining an interior chamber, the housing having an operational end and an opposite, bottom end, the interior chamber containing a motor acting through a transmission and configured for reciprocally driving a pair of laterally reciprocating drive fingers. Each drive finger includes an elongate finger drive element extending from the operational end. A resilient seal having slits accommodating the finger drive elements is captured in corresponding seal cavities in each of the housing halves. The seal and the housing halves are configured for placing the seal in at least one of radial and axial compression upon assembly of the housing halves together.

A stationary blade for the blade set suitable for use with a hair cutting appliance that includes of wall segments fixedly interconnected forming a segmented stack, wherein an intermediate wall segment is disposed between a first wall segment and a second wall segment jointly forming, at an end of the segmented stack at least one toothed leading edge comprising a plurality of mutually spaced apart projections defining a plurality of teeth and respective tooth spaces, wherein the intermediate wall segment comprises a cutout and wherein the cutout in the intermediate wall segment, the first wall segment and the second wall segment define therebetween a guide slot for a movable blade.

An automated hairstyle processing method, an automated hairstyle processing system, and an automated hair cutting device, the system including a memory unit arranged to store a predefined hairstyle model including hair property representing values and body shape representing values, a sampling unit arranged to sample an actual body shape, of a to be treated subject, involving detecting deviations from a model body shape portion of the predefined hairstyle model, a processing unit arranged to adapt a hair property model of the predefined hairstyle model, when deviations between the actual body shape and the model body shape portion are detected, so as to compensate the actual body shape deviations, the adaptions to the hair property model being local adaptations.
