MUMBAI, India, April 17 -- Intellectual Property India has published a patent application (202531092306 A) filed by Narula Institute Of Technology, Kolkata, West Bengal, on Sept. 25, 2025, for 'nonlinear state-space modelling of respiratory mechanics using bio-signals.'
Inventor(s) include Dr. Moupali Roy; and Dr. Sangita Roy.
The application for the patent was published on April 17, under issue no. 16/2026.
According to the abstract released by the Intellectual Property India: "The present invention provides a system and method for constructing a nonlinear state-space model of the respiratory system using measured bio-signals, such as pressure, flow, and volume. The method employs advanced system identification techniques to estimate nonlinear dynamics that characterize lung compliance, airway resistance, and tissue viscoelasticity. Unlike conventional linear models, this invention adapts to inter-patient variability, disease states (e.g., COPD, asthma), and external influences such as mechanical ventilation. The device includes real-time acquisition of bio-signals via sensors, followed by pre-processing, model structure selection, parameter estimation using optimization algorithms (e.g., recursive least squares, EKF, neural networks), and model validation. The resulting nonlinear model is capable of supporting adaptive control, diagnosis, and personalized ventilation strategies. The invention has applications in clinical diagnostics, telemedicine, implantable devices, and smart respiratory support systems."
