Title: Innovations of Alessandro Guazzi
Introduction
Alessandro Guazzi is a notable inventor based in Oxford, GB. He has made significant contributions to the field of signal processing and vital signs measurement, holding a total of 3 patents. His work focuses on developing methods and apparatuses that enhance the accuracy of physiological signal analysis.
Latest Patents
One of his latest patents is a signal processing method and apparatus. This invention estimates the frequency of a dominant periodic component in an input signal by modeling the input signal using auto-regressive models of various orders. It generates candidate frequencies for the periodic component and calculates the cross-correlation of synthetic signals with the original signal. The frequency with the highest cross-correlation is taken as the estimate for the dominant periodic component. This method can be applied to any noisy signal with a suspected periodic component, such as physiological signals like photoplethysmogram signals, aiding in the estimation of heart rate and breathing rate.
Another significant patent is a method and apparatus for vital signs measurement. This invention monitors changes in oxygen saturation by analyzing a three-color channel video image of the exposed skin of a subject. It involves obtaining normalized signals from each color channel and averaging them across multiple regions of interest. The changes in the ratio of amplitudes from different color channels are output as a measure of changes in blood oxygen saturation.
