Latest Patents
Among his latest patents, two notable inventions stand out:
1. **Photoplethysmographics using phase-division multiplexing** - This invention applies first and second carrier signals that are distinguishable by phase to infrared and red energy emitters. A detector captures the modulated energy, which allows for a thorough analysis of both the infrared and red components. The invention utilizes time-varying periodic signals with identical frequencies, a preferred 90-degree phase difference, and strategically chosen carrier frequencies to minimize ambient light interference.
2. **Photoplethysmographics using component-amplitude-division multiplexing** - This patent describes a system where multiple carrier signals, differentiated by their amplitude, are used with various energy emitters. The system is designed to receive modulated energy from each emitter wavelength and enables precise demultiplexing, which can uncover signal components and mitigate errors caused by external light sources during the detection process.
