Latest Patents

Among his latest patents, one noteworthy innovation is the "Demodulating a signal from intermittently illuminated region." This invention revolves around a system that can intermittently illuminate a specified area, detect incoming light to generate a detected signal, and subsequently process this signal with a specialized demodulator. The demodulator is designed with a capacitor and a resistor, along with a switch that connects to ground when the area is not illuminated. This design effectively produces a high-pass filtered output during illumination, while maintaining a stable ground signal during periods without light, thereby mitigating the impact of low-frequency noise sources such as background light and other interferences.

Another significant patent filed by Pickett is the "Frequency domain adaptive motion cancellation filter." This innovation involves various systems and methods for implementing adaptive filters that operate in the frequency domain. The method employs an optical signal associated with a physiological function and integrates motion data obtained from an accelerometer. Through the use of gradient descent techniques, the method calculates coefficients representing the relationship between the optical signal and motion spectrum, ultimately generating a cleansed optical signal free from motion artifacts.
