System and method for obtaining vital sign related information of a living being

The present invention relates to a device, system and method for obtaining vital sign related information of a living being. The proposed device comprises an input unit for receiving an input signal generated from light received in at least one wavelength interval reflected from a skin region of a living being, said input signal representing vital sign related information from which a vital sign of the living being can be derived, a processing unit for processing the input signal and deriving vital sign related information of said living being from said input signal, an orientation estimation unit for estimating the orientation of said skin region, and a control unit for controlling an illumination unit for illuminating said skin region with light to illuminate said skin region based on the estimated orientation of said skin region and/or for controlling said processing unit to derive vital sign related information from said input signal obtained during time intervals selected based on the estimated orientation of said skin region.</p

The present invention relates to a device, system and method for obtaining vital sign related information of a living being (3). The proposed device comprises an input unit (12) for receiving an input signal (32) generated from light (31) received in at least one wavelength interval reflected from a skin region (2) of a living being (3), said input signal representing vital sign related information from which a vital sign of the living being can be 5 derived, a processing unit (14) for processing the input signal (32) and deriving vital sign related information (36) of said living being from said input signal (32), an orientation estimation unit (16) for estimating the orientation of said skin region (2), and a control unit (18) for controlling an illumination unit (40) for illuminating said skin region (3) with light (41) to illuminate said skin region (2) based on the estimated orientation of said skin region 10 (2) and/or for controlling said processing unit to derive vital sign related information (36) from said input signal obtained during time intervals selected based on the estimated orientation of said skin region (2).</p

Device and method for extracting information from characteristic signals

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)
