Title: Innovations of Robert Smith in Photoplethysmography
Introduction
Robert Smith is an accomplished inventor based in Corona, California. He has made significant contributions to the field of photoplethysmography, holding three patents that showcase his innovative approach to medical technology. His work focuses on improving the accuracy and efficiency of detecting blood flow and other vital signs.
Latest Patents
Smith's latest patents include groundbreaking technologies in photoplethysmography. The first patent, titled "Photoplethysmographics using phase-division multiplexing," describes a method where first and second carrier signals are applied to infrared and red energy emitters. This allows a detector to receive the sum of the energy after modulation at these wavelengths. The signal is then demultiplexed, enabling the determination of both infrared and red modulation components. The preferred phase difference of 90 degrees enhances the effectiveness of this technology.
The second patent, "Photoplethysmographics using component-amplitude-division multiplexing," involves multiple carrier signals that are distinguishable by their amplitudes. These signals are applied to various energy emitters, allowing a detector to receive the modulated energy. The output is demultiplexed to determine the modulation components at each emitter wavelength. This innovation provides sufficient information to detect and correct errors caused by ambient light and other interferences.
