ABSTRACT:
Portable pulse rate detecting device for contact with human body tissue, including a light-emitting source for emitting radiant energy directed at through human body tissue; at least first and second light detectors for detecting intensity of radiant energy after propagation through human body tissue and for providing first and second input signals as a function of such propagation, a detecting device for providing a motion reference signal, and processing means for removing motion-related contributions from the first and second input signals and subtracting a calculated model based on the motion reference signal from each of the first and second input signals, wherein the processing means is also for removing measurement noise and residual non-modeled contributions from the first and second enhanced signals using a noise reduction algorithm.
