MUMBAI, India, July 5 -- Intellectual Property India has published a patent application (202517054887 A) filed by Dolby Intellectual Property Licensing, Llc, San Francisco, on June 6, for 'foreign object detection and friendly metals.'
Inventor(s) include Kanakasabai, Viswanathan; Ganesh, Jayanti; Tatikonda, Subbarao; and Narayana Bhat, Suma Memana.
The application for the patent was published on July 4, under issue no. 27/2025.
According to the abstract released by the Intellectual Property India: "This disclosure provides systems, methods and apparatuses for object detection by a Power Transmitter (PTx) that supports both induction heating and wireless power transfer. An object detection assessment is based on a measurement value obtained while the PTx transmits an object detection pulse (also referred to as an object detection signal). When the PTx determines that a Power Receiver (PRx) is present in the magnetic field of the PTx, the can also compare the measurement value to various thresholds to determine whether a foreign object is also present in the magnetic field. The various thresholds include a PRx threshold range. In some implementations, the PRx threshold range can enable the PTx to discern between a foreign object and a PRx that contains friendly metals that would otherwise be detected as foreign objects. In some implementations, an object detection assessment can be combined with a coupling factor measurement to concurrently detect for a foreign object and calculate the coupling factor between the PTx and the PRx."
The patent application was internationally filed on Nov. 14, 2023, under International application No.PCT/US2023/079619.
