Title: Innovations by Andras Boross in Optical Pulse Detection
Introduction
Andras Boross is a notable inventor based in Fremont, California, recognized for his contributions to the field of non-invasive medical technology. He holds two patents that focus on improving the accuracy of pulse oximeters, which are essential devices for measuring blood oxygen levels.
Latest Patents
His latest patents include a method and apparatus for detecting optical pulses. This innovation enhances the calculation of oxygen saturation and other blood constituents by utilizing non-invasive pulse oximeters. The method allows for a more accurate determination of blood flow by collecting time-measures of the absorption signal at two or more wavelengths. The collected data is processed to obtain composite pulsatile flow information, from which artifacts have been filtered. The processing can occur in either the time domain or the frequency domain. In the preferred time domain embodiment, successive portions of periodic information are weighted and added together in synchrony to obtain the composite pulse information. In the frequency domain embodiment, the time-measure is Fourier transformed into its spectral components to form the composite information. Additionally, a new method for correlating the heartbeat and optical pulse is provided, where a product of the ECG R-wave and optical pulse signals corresponding to the same heartbeat is obtained. One signal is time-shifted relative to the other until a maximum waveform product corresponding to the heartbeat is determined.
