The application for the patent was published on September 25, 2026, under issue no. 39/2026.
Abstract: A portable multi-parameter physiological monitoring system comprises an ADS1293 ECG analog front-end (15) for acquiring electrocardiogram signals, an AFE4490 PPG analog front-end (17) for acquiring dual-wavelength photoplethysmography signals, and a DS18B20 temperature sensor (13) for acquiring body-temperature data. A Raspberry Pi 5 (12) synchronously acquires and processes the physiological signals through respective digital signal-processing pipelines. ECG processing includes filtering and morphology-preserving smoothing (62–67) to generate a filtered ECG output (68) and R-peak detection (69). PPG processing (72–77) generates a filtered PPG output (78) and enables pulse peak detection (79) and SpO2 ratio computation (70). A trained deep-learning model performs local cardiac-condition classification using processed ECG signals. Processed physiological parameters, waveforms and classification outputs are communicated to a remote computing platform (41) for visualization through web and mobile interfaces.
