    Abstract: The present invention relates to a device (10), system (1) and method (200) for use in blood oxygen saturation measurement of a subject. To enable blood oxygen saturation measurements with improved reliability, a processing device (10) is presented comprising an input (11) for receiving first and second detection data of a tissue region of the subject, said first detection data being data acquired over time by detecting radiation at a first wavelength (λ1) and at a second wavelength (λ2) received from said tissue region; said second detection data being data acquired over time by detecting radiation at the first wavelength and at the second wavelength received from said tissue region in response to coherent light at the first wavelength and coherent light at the second wavelength being emitted towards the tissue region; a PPG unit (12) for deriving, from said first detection data, a first PPG signal indicative of an absorption of light within the tissue region at the first wavelength, and a second PPG signal indicative of an absorption of light within the tissue region at the second wavelength; a flow unit (13) for deriving, from said second detection data, a first flow signal indicative of a flow of light scattering particles within the tissue region probed at the first wavelength, and a second flow signal indicative of a flow of light scattering particles within the tissue region probed at the second wavelength; and a processing unit (14) for correcting said PPG signals based on said flow signals and/or for providing a feedback signal based on a comparison of the first and second flow signals.

    Abstract: A skin treatment system including a treatment device to treat a treatment region of a body. The skin treatment system includes a camera to capture at least one image of skin, the image having an imaging region, and to provide captured image data representing the captured image. The imaging region has a predefined spatial relationship with the treatment region. The skin treatment system further includes a storage facility for storing reference image data indicative of a reference image of the skin. The skin treatment system further includes an orientation estimation facility to determine which part of the reference image corresponds to the at least one captured image, using the captured image data and the reference image data, and to derive from a predetermined orientation of said corresponding part with respect to the reference image, an orientation indication indicative of an orientation of the treatment device with respect to the body.

    Abstract: A hair cutting device (10) is provided comprising a cutter unit (11), a skin stretcher (12) and slit adapting means. The cutter unit (11) comprises a skin-contact surface for dragging over a skin surface (21) in a shaving direction (55), a front surface arranged in front of the skin-contact surface in the shaving direction (55), and a laser beam exit window arranged in the front surface for allowing a hair cutting laser beam (13) to cut a hair (22) near the skin surface (21) in front of the front surface. The skin stretcher (12) is positioned in front of the cutter unit (11), according to the shaving direction (55), and comprises a stretcher surface for dragging over the skin surface (21) together with the skin-contact surface, such that a skin dome (23) is formed by the skin surface (21) in a slit between the skin stretcher (12) and the cutter unit (11). The slit adapting means are provided for adapting at least one dimension (51, 52, 54) of the slit for controlling a shape of the skin dome (23).

    Abstract: The present application relates to a method for setting a cutting distance (δlaser13 skin13 opt(z)) between a laser beam (14) and a skin surface (5) in a laser shaving device (1), said laser shaving device having a laser deactivation threshold (δlaser_skin_opt(z)), said method comprising: operating an optical system (12) to generate the laser beam; determining a skin variation value (σ) indicative of the variation in the distance of the skin surface from a reference point; determining a cutting distance between said laser beam and the skin surface in dependence on at least the laser deactivation threshold and said skin variation value; and adjusting said optical system to locate the laser beam in dependence on said determined cutting distance. Determining the said skin variation value comprises the steps of generating information indicative of an ideal skin surface (Yskin(z)) and the distances from said ideal skin surface that said skin surface is; and determining a standard deviation of said skin surface distance from said ideal skin surface.

    Abstract: The present disclosure pertains to a system and method for monitoring and for facilitating pulmonary and systemic hemodynamics in the treatment and/or prevention of cardiac arrhythmias or structural cardiac changes, caused by altered preload. The system comprises: a pressure generator; a first sensor configured to generate output signals conveying information related to venous blood accumulation during cardiac preload in the subject; a second sensor configured to generate output signals conveying information related to systemic arterial circulation in the subject; and one or more hardware processors configured by machine-readable instructions to control the pressure generator to adjust the pressure levels of the flow of breathable gas during one or both of inhalation and exhalation to facilitate the pulmonary and systemic circulation based on the output signals from the first sensor and the second sensor.

    Abstract: The present application relates to a device for cutting hair comprising a skin contacting face (3) that is placed against a surface of the skin (6) of a user during use. The device also has an optical system configured to direct a cutting laser beam (8) across a cutting zone (5) parallel to and spaced from said skin contacting face to cut hairs extending into the cutting zone. Also provided is a laser positioning mechanism which is arranged so that, during use of the device, the distance (H1) between said cutting laser beam and said skin contacting face is changed to maintain a predetermined distance between the cutting laser beam and the surface of the skin of a user.
