MUMBAI, India, April 17 -- Intellectual Property India has published a patent application (202641043372 A) filed by Bapatla Surendra Babu; and Irukumalli Priyanka, Tenali, Andhra Pradesh, on April 5, for 'stress-relaxation overtone-ratio aging-trajectory self-prognosticating oscillator apparatus exploiting anharmonic kinetics.'
Inventor(s) include Bapatla Surendra Babu; and Irukumalli Priyanka.
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: "A self-prognosticating oscillator apparatus executes proactive frequency compensation by utilizing residual stress relaxation as an active diagnostic metric. Conventional oscillators suffer unpredictable long-term frequency drift requiring costly external recalibration. The proposed solution includes a piezoelectric resonant element (110) possessing multi-timescale residual stress (120), driven by sustaining circuitry (130). A ratio measurement circuit (140) tracks a frequency ratio between the fundamental and a higher-order vibrational mode. As stress relaxation (210) drives logarithmic frequency aging (220), the ratio drifts. An aging prognosis processor (320) extracts an overtone ratio drift rate (330) to determine a current aging rate (340). Comparing the ratio to an asymptotic overtone ratio (310) yields a remaining ratio deviation (350) and remaining aging potential (360). The processor computes a predictive future aging trajectory (410). A proactive compensation engine (420) applies pre-calculated corrections, yielding a stabilized output signal (430) demonstrating holdover improvement (440) during GPS outages, enabling intelligent recalibration scheduling (450)."
