MUMBAI, India, June 30 -- Intellectual Property India has published a patent application (202641075638 A) filed by Amrita Vishwa Vidyapeetham on June 18, 2026, for A Smartphone-Based System For Analysis Of A Breathing Sound Signal Of A Subject.
Inventors include Rauniyar, Aman Kumar; Gupta, Abhishek; and Muthaiah, U..
The application for the patent was published on June 26, 2026, under issue no. 26/2026.
Abstract: The present disclosure provides a system (100) for analysis of a breathing sound signal of a subject and a method (300) for analysis of the breathing sound signal of the subject during sleep. The system (100) includes a microphone (102) of a smartphone, a signal conditioning unit (104), a transform unit (106) that yields a composite spectral representation from a Mel-scale spectral component (106-2), a Mel-scale cepstral component (106-4), and a pitch-class component (106-6) in combination, a convolution stack (108) that carries bypass paths between non-adjacent stages, a parameter set (110), and an inference unit (112) that yields an indication of a breathing interruption pattern. Unlike conventional arrangements that demand dedicated recording hardware under controlled clinical conditions, the system (100) renders acoustic assessment of breathing interruption patterns accessible across home-based sleep monitoring and telemedicine deployments.
