According to the abstract released by the Intellectual Property India: "This invention discloses a Method and System for Wireless Power Transfer (WPT) employing Resonant Inductive Coupling, designed to overcome limitations in efficiency and adaptability. The system features a transmitter with multi-coil arrays driven by a variable-frequency oscillator, receivers with tuned secondary circuits, and an integrated control layer using machine learning for real-time optimization. Core elements include: (1) Position-sensing sensors (e.g., ultrasonic or magnetic) for detecting receiver locations; (2) Adaptive tuning via variable capacitors and inductors, adjusted by neural network models predicting optimal parameters from input data like distance and load; (3) Beamforming algorithms to focus magnetic fields on specific devices, enabling multi-receiver charging without power dilution; (4) A hybrid feedback protocol combining wireless communication (BLE) with in-band modulation for rapid response to environmental changes. Novel aspects encompass ML-driven dynamic resonance, achieving 92% average efficiency across 10-50 cm ranges, a 25% improvement over static systems. Prototypes demonstrate safe operation with EMI below ICNIRP limits and thermal rise 5 C. The method involves initialization, sensing, predictive tuning, power delivery, and continuous monitoring. Applications span consumer electronics, electric vehicles, and biomedical implants, fostering energy-efficient ecosystems. Evaluation on testbeds with varying loads shows robust performance, reducing global energy waste in charging infrastructures. This patent advances WPT by integrating intelligence, scalability, and safety, aligning with sustainable technology goals."
