Abstract: 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.

Abstract: A device and a method for extracting information from detected characteristic signals are provided. A data stream (26) derivable from electromagnetic radiation (20) emitted or reflected by an object (10) is received. The data stream (26) includes a continuous or discrete characteristic signal (68) including physiological information (30) indicative of desired object motion to be detected and utilized so as to extract at least one at least partially periodic vital signal of interest. A plurality of characteristic index elements (60) can be derived from the data stream (26) through a dimensional reduction (66). The plurality of characteristic index elements (60) includes a directional motion component (70) associated with a disturbance-reduced index element (40) having a determined orientation substantially aligned with a reference motion direction (41) indicative of the desired object motion. Consequently, dimensional reduced data can be utilized for detecting the vital signal of interest.

Abstract: The invention relates to a control system (100) for an ambient light environment in a room in a hospital environment. The control system is configured to time and synchronize light effects of the ambient light environment (170, 190) in response to sensor signals (111-113) from patient location sensors (121) or other sensors (122,123) for detecting if a clinical instrument is activated, moved or taken into use or for detecting heart rate. Light effects may be used by the clinical personnel to improve quality and speed of the examination and to create a calming atmosphere for the patient. However, different light effects are required at different times and for different durations. Therefore, timing of the light effects relative to sensor signals may improve workflow and patient comfort.
