Introduction

Sara Mariani is an inventor associated with Cambridge, Massachusetts, and Koninklijke Philips N.V. Her work includes a patent for measuring respiration rate over long distances using noisy, irregularly sampled sensor signals.

Latest Patents

Mariani is listed as an inventor on 1 patent, titled “Methods for Long-Distance Respiration Rate Measurement Using Noisy and Irregularly Sampled Sensor Signals.” The invention describes a system that processes a sensor signal to estimate a person’s breathing rate.

The system normalizes the sensor output and applies four Discrete Prolate Spheroid window functions. For each windowed signal, it computes a Lomb–Scargle periodogram, then combines the periodograms using a weighted average. It identifies the frequency corresponding to the peak estimated spectral density and uses that frequency to produce breaths-per-minute data.

Career Highlights

The patent reflects work on signal processing methods designed to estimate respiration from sensor data that may be noisy or collected at irregular intervals. Such methods can support remote physiological monitoring.

Collaborations

The provided information identifies Ikaro Garcia Araujo Da Silva as a coworker. It does not specify their role in the patent or the nature of their collaboration.

Conclusion

Sara Mariani’s listed patent focuses on using signal-processing techniques to derive respiration-rate measurements from challenging sensor signals, highlighting an approach to long-distance respiratory monitoring.
