    摘要： The invention relates to methods and apparatus for monitoring movement and breathing of two or more subjects occupying common bedding. Particularly, the invention relates to a method for monitoring movement of subjects located in a common bedding, the method comprising the steps of: —imaging the bedding by an optical sensor; —performing a motion estimation by producing motion vectors indicating the local displacement of corresponding image blocks between consecutive images, or images that are several frames apart, received from said optical sensor; —calculating motion clusters by measuring spatial and temporal correlations of the motion vectors; —segmenting the calculated motion clusters by assignment of each motion cluster to a corresponding subject, wherein the assignment of the motion clusters to the corresponding subject is based on the spatial and/or temporal similarity of the motion clusters among each other and on previous segmentation results.

    摘要： The invention relates to a respiratory motion detection apparatus (1) for detecting respiratory motion of a person. An illuminator (3) illuminates the person (2) with an illumination pattern (11), and a detector (4) detects the illumination pattern (11) on the person (2) over time. A temporal respiratory motion signal being indicative of the respiratory motion of the person (2) is determined from the detected illumination pattern by a respiratory motion signal determination unit (5). The illumination pattern deforms significantly with slight movements of the person. Thus, since the respiratory motion signal determination unit (5) is adapted to determine the temporal respiratory motion signal from the detected illumination pattern, even slight respiratory movements of the person can be determined. The sensitivity of detecting respiratory movements of a person can therefore be improved.

    摘要： A hair treatment device is provided comprising a light-based detector (10) for detecting a hair (11) near a skin (12) surface. The light-based detector comprises a light source (13) for emitting optical radiation of at least a first wavelength and with an incident polarization towards the skin surface. A light sensor (14a, 14b) is provided for detecting light reflected at the skin surface. The light sensor (14a, 14b) is capable of separately detecting he reflected light with the incident polarization and with a different polarization and for providing a PP value representing the detected light with the incident polarization and a CP value representing the detected light with the different polarization. A processor (15) is operative to scale the CP value and the PP value to respective dynamic ranges, to determine a Minimum Intensity Projection (MIP) value by selecting the lowest value of the scaled CP value and the scaled PP value and to discriminate between the skin surface (12) and the hair (11) based on the minimum intensity projection.
