One data processing equipment is disclosed for vital signs needed for extracting one, include the physiological information component from sensor information, it includes that first sensor data related to time include physiological information component and at least one motion artifact component, it includes second sensor data related to time, a position, a speed or the acceleration in the region that the function representation as the time senses. One decomposition unit decomposes second sensor data at decomposed sensor information and at least two components based on decomposed second sensor data, at least provides two different sets of the motion reference data at least two different motion reference data channels. One artifact removal unit determines vital signs, at least one two motion reference data of a linear combination and motion reference data channel from first sensor data are formed.
