Latest Patents

One of Bhavin B Shah's latest patents is titled "Separating motion from cardiac signals using second order derivative of the photo-plethysmogram and fast fourier transforms." This invention is directed toward a pulse oximetry system designed to determine physiological parameters while effectively removing motion artifacts from physiological signals. The system comprises both a hardware subsystem and a software subsystem. The software works in conjunction with the hardware to perform a method that removes multiple motion artifacts from photo-plethysmographic data and obtains a measure of at least one physiological parameter. The method involves acquiring raw photo-plethysmographic data, transforming it into the frequency domain, and analyzing the transformed data to locate candidate cardiac spectral peaks. The process continues with reconstructing a photo-plethysmographic signal in the time domain, computing the second order derivative of the reconstructed signal, and analyzing it to determine the presence of cardiac physiologic signal characteristics. Finally, the best physiologic candidate is selected based on a second derivative scoring system, which can also be applied using other derivative processing analyses.
