Title: Innovations of Ross Flewelling
Introduction
Ross Flewelling is a notable inventor based in Oakland, CA, who has made significant contributions to the field of non-invasive medical technology. With a total of 14 patents to his name, he has focused on developing innovative solutions that enhance the accuracy and efficiency of physiological measurements.
Latest Patents
One of Flewelling's latest patents is a motion-compatible sensor for non-invasive optical blood analysis. This advanced optical sensor utilizes motion signals to calculate the physiological characteristics being measured. For applications such as pulse oximetry, techniques like least squares or ratio-of-ratios can be applied to the motion signal itself. The innovation lies in selecting a site on the patient where variations in motion produce signals of two wavelengths that are sufficiently correlated. Notably, a sensor placed on a nail, particularly a thumbnail, has been found to exhibit characteristics that allow the red and infrared signals to correlate effectively when used for pulse oximetry. The resulting signals correlate directly to arterial oxygen saturation, showcasing the potential of this technology in medical diagnostics.
