摘要： Monitoring of infants in an incubator may use cameras to measure vital signs and other medical parameters, including oxygen saturation of arterial blood. However, the images obtained by these cameras suffer from a reduced signal-to-noise ratio due to specular reflectance from light reflecting off the skin of the infant. By including radiation scattering structures within the incubator walls and light sources arranged along the edges of the incubator walls, diffuse illumination may be achieved, specular reflectance may be reduced, and the above-mentioned adverse affects on the signal-to-noise ratio of the camera images may be avoided and/or reduced.

摘要： The present invention relates to a device and a method for extracting information from detected characteristic signals. A data stream (76, 78, 80, 82) derivable from electromagnetic radiation (14) emitted or reflected by an object (11) is received and a plurality of characteristic index elements (50) varying over time can be extracted therefrom. The index elements (50) comprise physiological information (48) indicative of at least one at least partially periodic vital signal (12), and a disturbing signal component (58). For eliminating the disturbing signal component (58) to a great extent, the characteristic index elements (50) can be projected to a disturbance-reduced index element (64) having a distinct orientation in relation to a presumed orientation of the disturbing signal component (58). The disturbance-reduced index element (64) is chosen so as to reflect a dominant main orientation and length of the disturbing signal component (58) over time. Consequently, the mainly genuine physiological information (48) extracted from the data stream (76, 78, 80, 82) in this way can be utilized for determining the at least one at least partially periodic vital signal (12).
