Title: Innovations by Eric D Helfenbein
Introduction
Eric D Helfenbein is an accomplished inventor based in Sunnyvale, CA. He has made significant contributions to the field of medical technology, particularly in the area of cardiac monitoring. With a total of 4 patents to his name, Helfenbein's work focuses on innovative techniques for detecting and analyzing cardiac and respiratory signals.
Latest Patents
One of Helfenbein's latest patents is titled "Intramyocardial anomalous activity detection by subtracting modeled." This technique provides a method for detecting repeating patterns of anomalous intramyocardial Wenckebach electrical activity in patients. The method involves processing electrical potential signals that include both cardiac and respiratory components. By estimating the respiratory component through regression curve-fitting techniques, Helfenbein's method determines the presence or absence of intramyocardial anomalies. A generalized inverse of a matrix representing Wenckebach basis functions is utilized to analyze the differences between the electrical potential and the estimated respiratory component.
Another notable patent is the "Apparatus and method for determining respiratory effort from muscle." This invention includes a device for acquiring electrocardiographic (ECG) signals that contain both pure cardiac signals and respiratory muscle tremor (RMT) signals. The apparatus processes the ECG signal using a filter to reduce the cardiac signal, allowing for the determination of a waveform that represents the magnitude of oscillations in the filtered ECG signal. This waveform is then related to the respiratory muscle tremor, providing an estimation of the patient's respiratory effort derived entirely from the ECG signal.
