MUMBAI, India, June 27 -- Intellectual Property India has published a patent application (202547058875 A) filed by Google Llc, Mountain View, U.S.A., on June 19, for 'on-head detection and/or hearable-adjustment detection using active acoustic sensing.'
Inventor(s) include Fan, Xiaoran; and Thormundsson, Trausti.
The application for the patent was published on June 27, under issue no. 26/2025.
According to the abstract released by the Intellectual Property India: "Techniques and apparatuses are described for performing on-head detection and/or hearable-adjustment detection using active acoustic sensing. A hearable (102), such as an earbud, is capable of performing audioplethysmography (110). Audioplethysmography (110) is an active acoustic method capable of sensing subtle physiologically-related changes observable at a user's (106) outer and middle ear (108). The hearable (102) forms at least a partial seal in or around the user's (106) outer ear (108), which enables formation of an acoustic circuit involving the seal (118), the hearable (102), an ear canal (116), and an ear drum (120). By transmitting and receiving acoustic signals, the hearable (102) can recognize changes in the acoustic circuit to perform aspects of on-head detection (112) and/or hearable-adjustment detection (114). The size, cost, and power usage of the hearable (102) can help make these features accessible to a larger group of people and improve the user experience with hearables (102)."
The patent application was internationally filed on Mar. 15, 2024, under International application No.PCT/US2024/020238.
