20090043216 | HEART BEAT SIGNAL RECOGNITION - A subject's heart rate is determined by recognizing heart beat patterns in a heart beat signal. A heart rate monitor receives a Doppler signal reflected from an artery of a target, performs demodulation and heart beat recognition techniques on the received signal to determine a set or sequence of features in each frame of the signal. Once a feature sequence is extracted from the signal, pattern classification is performed to determine if the extracted feature sequence is associated with one or more heart beats. The pattern classification may include finding the optimal state sequence by calculating the probability of each allowable state sequence based on the extracted feature sequence and heart beat models or additional noise models. Another pattern classification technique may determine a heart beat candidate using frame energy and dynamic thresholding methods followed by computing the probabilities between the feature sequence and each stored heart beat model or additional noise models. A further pattern classification technique may identify heart beat candidates using frame energy and dynamic thresholding methods and compute the similarity between the feature sequences and each of the stored heart beat templates. Post-processing is applied to heart beat candidates to determine if the candidates are associated with a true heartbeat, noise or some other signal source.
