Abstract: A subject's heart rate is determined. A heart rate monitor receives a Doppler signal reflected from an artery of a target, performs demodulation and heart beat recognition techniques to determine a set of features in each frame of the signal. Pattern classification is performed to determine if the extracted feature sequence is associated with 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. Or, a heart beat candidate is determined using frame energy and dynamic thresholding followed by computing the probabilities between the feature sequence and each stored heart beat model or additional noise models. Or, heart beat candidates are determined using frame energy and dynamic thresholding which compute the similarity between the feature sequences and each of the stored heart beat templates.

Abstract: 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. Once a true heart beat is identified, the subject heart rate is updated based on the detected heart beat and displayed for a user.

Abstract: A heart rate monitor for calculating heart rate based upon EKG signals. The monitor preferably utilizes 3 electrodes to pick up EKG signals and a differential amplifier to cancel common mode signals in the output of the electrode. An analog bandpass filter comprised of a low pass and high pass filter in series each with different rolloffs filters out low and high frequency components. The signals are digitized and digital filtering to remove power line hum and remnants of low and high frequency noise is performed. Then the EKG signals are digitally enhanced by differentiating and squaring the results of the differentiator then being averaged in a moving average computation so as to generate enhanced digital data. The enhanced digital data is then processed to learn the EKG characteristics, and a heart rate arbitrator processes the incoming signals to select out actual EKG complexes from EMG noise and other noise. The EKG isolation process is done using rules of reason and the learned characteristics of the EKG signal.

Abstract: A monitor provides a wireless signal with respective pulses, based on a heartbeat, repetitive physical movement, or other repetitive bodily action of a user. The pulses include longer duration pulses whose duration identifies the monitor, and distinguishes it from other monitors which may provide crosstalk interference. The longer duration pulses are interspersed among short duration pulses to reduce power consumption. The pulses are transmitted in successive cycles, where the number of the longer duration pulses is set adaptively in each cycle based on a detected rate, or rate of change, of respective instances of the bodily action. A receiver unit processes the signal to determine a rate of the bodily action and provide a corresponding output. The receiver unit can synchronize with two or more consecutive longer duration pulses. The pulse duration can be fixed or determined dynamically, e.g., non-deterministically.

Abstract: A heart rate monitor with analog and digital input mechanisms is provided with electro static discharge (ESD) protection which protects electrical components within the monitor. The heart rate monitor input mechanisms may include externally exposed sensors comprised of a conducting material, such as metal. The sensors may include push buttons, a dial, and one or more sensors for retrieving a heart rate signal, such as a case back for the monitor device. Internal circuitry such as an integrated circuit (IC) performs operations to provide time, a heart rate, and other information through a display. The ESD protection prevents any voltage discharge accumulating on the externally exposed sensors from reaching the one or more ICs and interrupting or negatively affecting performance of the monitor.

Abstract: A heart rate monitor implements power saving algorithms while monitoring a subject's heart rate. The monitor continuously monitors a subject during an initial period to determine an initial heart rate. After the initial heart rate is acquired, power may not be provided for portions of the monitor until a heart beat is expected to occur. At some point before the expected heart beat occurs, power is returned to the components which have not received power. The expected heart beat is then detected, and power to selected portions of the monitor is terminated again until another expected heart beat approaches in time. By providing power to monitor components just before an expected heart beat, the monitor may still detect the heart beat and determine the corresponding heart rate of the user. The period of time during which power is terminated for some components may be determined from the detected heart rate. The number of heart beats during which power is terminated for selected monitor components may vary.
