Title: Usman Mahmood Khan: Radar-Based Identification and Soil-Moisture Sensing

Introduction

Usman Mahmood Khan is an inventor based in Raleigh, North Carolina. His work includes radar-based approaches to identifying people through vital signs and estimating soil moisture without contact. He has 2 patents.

Latest Patents

Khan’s patent, “Radar Identification of Persons via Vital Signs,” describes an apparatus that emits radar signals and analyzes their reflections to determine a person’s vital signs. A machine-learning model then compares those measurements with previously collected vital-sign data to calculate a similarity score for identification.

His patent, “Contactless Soil Moisture Estimation Using Radiofrequency Signals,” describes a system that transmits and receives radiofrequency signals to assess soil layers. The system analyzes signal attenuation, phase changes, and power-delay profiles to estimate layer depth and dielectric permittivity, then uses those measurements to estimate moisture content.

Career Highlights

Khan’s listed professional affiliations include North Carolina State University and Koko Home, Inc. His patent work applies radiofrequency sensing to both human identification and agricultural measurement.

Collaborations

Khan’s listed coworker is Muhammad Shahzad. The available information does not specify the nature or scope of their collaboration.

Conclusion

Usman Mahmood Khan’s two patents demonstrate applications of radar and radiofrequency sensing in distinct fields, from identifying people through vital signs to estimating soil moisture.
