Title: Innovations of Raj Kumar Rakshit

Introduction

Raj Kumar Rakshit is a notable inventor based in Kolkata, India. He has made significant contributions to the field of radar technology, particularly in applications related to cardiopulmonary monitoring and machine health assessment. With a total of eight patents to his name, Rakshit has demonstrated a commitment to advancing technological solutions that address real-world challenges.

Latest Patents

One of his latest patents is titled "Method and system for optimum channel selection in twin radar for cardiopulmonary signal monitoring." This innovation focuses on selecting the best channel in twin radars to efficiently detect cardiopulmonary signal rates. Traditional solutions require continuous calibration and are affected by the distance of the radar from the monitored subject. Rakshit's approach enhances monitoring by utilizing a time domain method that considers only the data reflected off the radar. This solution is adaptive to time windows and employs radar physics-based methods to improve the detection of respiration and breath rates.

Another significant patent is "Method and system for monitoring machine health using radar-based segregation for induced machine vibrations." This invention addresses the need for monitoring vibrations in non-rotational components of machines, which is crucial for ensuring safe operational limits. Existing sensor-based approaches may not be practical in extreme environments. Rakshit's method offers a model-free, data-driven approach that processes micro Doppler signals captured by radar to estimate both rotational and translational frequencies of induced vibrations. A rule engine is then applied to alert users when vibrations exceed defined standards.
