Abstract: The present invention discloses a device and a method for controlling growth of hair on human skin with low doses of electromagnetic radiation, and a device for carrying out the method. In the method, radiation of a suitable spectrum is applied to the skin, in one or more pulses of between 1 and 100 ms, and with maximum fluencies on the skin between 1 and 12 J/cm2. By applying such low fluencies and at controlled pulse durations, follicles of the hairs are induced to the catagen phase. This means that the growth of the hairs of those follicles will stop. Although the method is not primarily aimed at immediate hair removal, hairs may be shed subsequently. In any case, further growth may be stopped for prolonged periods of time. The main advantage of the method is that the risk of damage to the skin is minimized.

Abstract: The invention provides a skin treatment device comprising a laser source (40) and focusing optics (50), such that a focal spot (18) is positioned in a dermis layer (24) of the skin to be treated. The laser beam (42) is powered and focused (16) such that a LIOB (laser induced optical breakdown) phenomenon is obtained, which affects the skin in order to stimulate re-growth of tissue. This in turn reduces wrinkles (30). The device may comprise wrinkle-determining means (52, 54, 56, 58). The focusing optics (50) may have a numerical aperture of at least 0.4. The invention also provides a corresponding method to treat skin, in particular to reduce wrinkles (30), by providing a focused laser beam (16) that causes LIOB in the dermis layer (24) of the skin. The advantage is that damage to overlaying epidermis layers may be avoided by the use of the very local LIOB phenomenon.

Abstract: The invention relates to an optical blade and a hair cutting device, adapted for cutting a hair near skin of a human body part or animal body part. The optical blade (1), especially for use in a hair cutting device, comprises a blade body (3) adapted for guiding optical radiation, and a tapered end (2) adapted for allowing the optical radiation to exit the optical blade (1), wherein the tapered end (2) comprises a reflector adapted for redirecting the optical radiation before it exits the optical blade. In this way the balance of closeness vs. irritation is improved beyond the capabilities of conventional shaving systems and an optical blade is provided which is insensitive to the type of shaving additive used, while the manufacturing of the optical blade is made easier and costs are reduced.

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.

The invention further relates to a method of improving wrinkle resistance in a fabric by use of such a compound.

Abstract: The invention relates to an iontophoretic device for the enhanced transport of substances through the skin (1), wherein at least two electrical transportation fields (Ep, Eo) with different directions are applied. In a preferred embodiment, these field are orthogonal and parallel to the skin surface, respectively, and applied in a temporally alternating sequence. Substances are thus transported in an optimal way on their meandering paths through the stratum corneum into or out of the skin. The iontophoretic device preferably comprises an array of electrodes (11) to which either a spatially alternating pattern of electrical potentials can be applied or which can alternatively be divided into two groups of neighboring electrodes that are connected to the same potential. The iontophoretic device may particularly be integrated into any skin-contacting device e.g. an electrical shaver.

The support structure (6) is configured such, that a space (A), restricted at one side by the shaving heads (5) and at the opposite side by the handle (2), is substantially open to its remaining, surrounding side.

Abstract: Systems and methods for achieving sub-surface, highly spatially selective cardiac ablation by means of laser induced optical breakdown (LIOB) are disclosed. Damage to non-targeted heart and artery/vein tissue is to be minimized according to the present disclosure. A catheter enters the heart, e.g., via a vein, and catheter location is determined/confirmed. Laser pulses are guided through the optical path within the catheter and, at or near the catheter end, a focusing structure is provided that focuses the laser radiation through the non-targeted vein/heart tissue into the targeted tissue. In the focusing structure, laser induced LIOB occurs and related mechanical effects affect the targeted tissue.

Abstract: The invention relates to a device (1) for treating human skin by means of radiation. The device comprises a housing (3) with a radiation exit opening (13). A radiation source (9) is accommodated in the housing. Radiation generated by the radiation source propagates from the radiation source towards the radiation exit opening via a radiation path (15) comprising a radiation filter having a predetermined transmission spectrum. According to the invention the radiation filter comprises a reflecting surface (23) via which the radiation propagating along the radiation path (15) is reflected. The reflecting surface has a coating which provides the reflecting surface with a reflection spectrum substantially matching the predetermined transmission spectrum. An advantage is that the reflection surface can be optimally and uniformly cooled, so that the heat generated as a result of the absorption of part of the radiation by the radiation filter can be effectively transmitted to a cooling system (25) of the device (1).

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).
