An electrically driven device includes a housing, an electric motor with a drive shaft having a first rotary axis and a drive pin connected to the drive shaft eccentrically with respect to the rotary axis, and a driven shaft having a second rotary axis and mounted in the housing for performing a pivoting about the second rotary axis. The driven shaft is coupled to the drive shaft by a gear mechanism having a scotch yoke mechanism converting a rotary motion of the drive shaft into a reciprocating pivoting motion of the driven shaft. The scotch yoke mechanism includes a cross slider receiving the drive pin and having a sliding support extending perpendicular to the first rotary axis. The cross slider is guided in the housing by at least two elastically deformable elements. The driven shaft is coupled to the cross slider by a pivotable crank arm, converting a rotary motion of the drive shaft into a reciprocating of the driven shaft.

A personal hygiene device has a resonant motor and a motor control unit for applying a periodic voltage signal with a driving frequency at the resonant motor for driving the resonant motor into an oscillating motion with an oscillating frequency equal to the driving frequency. The motor control unit comprises a synthesizer circuit for digitally synthesizing the periodic voltage signal from voltage pulses of variable length provided with a pulse frequency higher than the driving frequency such that at least two voltage pulses are applied at least in one of two half cycles of each period of the periodic voltage signal.

A skin treatment apparatus, preferably an epilator, comprising at least one detector for detecting approximation and/or contact with the skin and a control unit to actuate the device depending on the signal received from the detector. The control unit has at least one regulator which increases the speed of the drive unit upon detection of an increased resistance and/or current consumption by a sensor and/or decreases the speed of the drive unit upon detection of an decreased resistance and/or current consumption by a sensor.

A template for forming a contour on an eyebrow, having a hair-removing means, having a flat, flexible support, which has a support edge that follows the lower contour curve to be formed for the eyebrow and a hair-removing region adjoining this support edge, which is coated with a hair-removing means, and having an optical positioning aid provided on at least one lateral half of the template for positioning the template relative to the eyebrow. For a simple use of the template with reproducible results, it has a positioning aid on each of the two halves.

A hair cutting member includes an optical waveguide, a connecting member, and a bonding member. The optical waveguide includes a core and a cladding that covers at least a portion of the core. The optical waveguide is disposed so as to emit light to hair growing on a skin. The connecting member retains an end of the optical waveguide. The bonding member bonds the optical waveguide and the connecting member to each other. The core is disposed off-center toward the outer circumference of the cladding. When viewed from an end face of the connecting member, a first distance between a center of the end face and an optical axis of the core is shorter than a second distance between the center of the end face and a center of the cladding. The technology of the present disclosure makes it possible to adjust the optical system of a hair cutting device easily.
