Abstract: The present invention relates to an oxytocin release stimulation device (10?) that can be arranged at or close to skin of a user (40). The oxytocin release stimulation device (10?) comprises a lighting unit (14?) and a control unit (16?). The control unit (16?) controls the lighting unit (14?) such that the lighting unit (14?) provides light with specific wavelengths and radiant exposures to the skin of the user (40) for a duration that ensures stimulation of a release of oxytocin. Release of oxytocin allows to stimulate a milk ejection reflex and thus to support milk extraction, e.g. when the oxytocin release stimulation device (10) is used with a breast pump (100?). The oxytocin release stimulation device (10?) can furthermore allow to reach an oxytocin level during pregnancy that allows to reduce the risk of postpartum depression or that allows to facilitate induction of labor.

Abstract: A system and method for providing a radiation source is disclosed. In one arrangement, the radiation source includes a gas cell having a window, an optical fiber that is hollow and has an axial direction, an end thereof being enclosed within the gas cell and optically coupled to the window via an optical path, and a surface, disposed around the end of the optical fiber, and extending past the end of the optical fiber in the axial direction towards the window so as to limit one or more selected from: the exchange of gas between the optical path and the remainder of the gas cell, ingress of plasma towards or into the optical fiber, and/or radical flux towards etch-susceptible surfaces.

Abstract: The present disclosure is directed to enhanced sampling of bioanalytes from bodily fluids using wearable and/or insertable devices. In some embodiments, an apparatus (100, 500, 600) for sampling bioanalyte(s) in tissue (107, 507, 607) may include: a base (102, 502, 602) having conduit(s) adapted to receive fluid extracted from the tissue; microneedles (106, 306, 506, 606) fluidly coupled with the conduit(s) and adapted to be pierced into the tissue; a plurality of individually-controllable energy emitters (112, 114, 350, 612, 614); and logic (90) operably coupled with the plurality of individually-controllable energy-emitters. The logic may be adapted to operate a subset of the plurality of individually-controllable energy emitters to apply energy at a first subset of the microneedles to induce bioanalyte flow through tissue towards the first subset or a second subset of the microneedles, or through the first subset or a second subset of the microneedles.

Abstract: An optical blade and a hair cutting device is configured to cut a hair near skin of a human body part or animal body part. The optical blade maybe used in a hair cutting device and includes a blade body configured to guide optical radiation, and a tapered end configured to allow the optical radiation to exit the optical blade. The tapered end includes a reflector configured to redirect the optical radiation before it exits the optical blade.

The hair removal system comprises a hair detection device and a hair removal device (20; S3) operatively coupled to the hair detection device, wherein the hair detection device comprises an imaging device comprising a first image sensor (12; S1) which is constructed and arranged to detect an image of a part of a skin (30) to be treated, and a control unit (18) adapted to discern, in the image, a hair (32) on the part of the skin (30), and operatively coupled to the hair removal device (20; S3) so as to control its operation, characterized by preventing means coupled to the control unit (18) and being adapted to disable the hair detection device or the hair removal device during a preventing period after the control unit has discerned the respective hair for the first time.

Abstract: The invention provides a hair treatment device (40) comprising a light-based detector (10) for detecting a hair (22) near a skin surface (21) and a method for detecting a hair (22) near a skin surface (21). The detector (10) comprises a light source (11), optical elements (14, 16, 17, 18) and a polarization-sensitive light sensor (12, 13). The light source (11) generates a light beam (31) and the optical elements (14, 16, 17, 18) focus the light beam (31) at a hair (22) near the skin surface (21). The polarization-sensitive light sensor (12, 13) is provided for detecting light interacted with the hair (22) or the skin surface (21) and having a predefined linear polarization. The light source (11) and/or the optical elements (14, 16, 17, 8) are arranged to cause the light beam (31), when reaching the skin surface (21), to have a polarization direction which is time-invariant and spatially variant in cross-sections of the 10 light beam.

Abstract: A detector for detecting a birefringent object near a skin surface of a human body part or an animal body part includes a source for emitting optical radiation having first and second wavelengths and an incident polarization state. An imaging unit is configured to image the birefringent object near the surface includes a detection unit for detecting optical radiation scattered and/or reflected by the birefringent object and/or the surface at the first and second wavelengths. A control unit is configured to process a signal from the detection unit for discrimination between the birefringent object and the surface.
