MUMBAI, India, April 10 -- Intellectual Property India has published a patent application (202421075352 A) filed by Tata Consultancy Services Limited, Maharashtra, on Oct. 4, 2024, for 'methods and systems for channel identification using manifolds of an earelectroencephalography (ear-eeg) signal.'
Inventor(s) include Muralidharan, Kartik; Jayas, Tanuja; Gubbi Lakshminarasimha, Jayavardhana Rama; Anand, Adarsh; Rajalingam, Jhanavi; Kumar, Bhartendu; Sampathkumar, Vivek; and Pal, Arpan.
The application for the patent was published on April 10, under issue no. 15/2026.
According to the abstract released by the Intellectual Property India: "Brain monitoring is performed using an Ear-electroencephalography (Ear-EEG) which records synchronized electrical behaviour of neurons in brain at high temporal resolution using a wearable ear device. For proper functioning of the wearable ear device, sensor electrodes need to be within the ear to remain in constant contact with the skin. However, body movements tend to disrupt extent of contact, leading to noisy signals being captured, which are often difficult to distinguish from a valid EEG signal. Thus, identification of channels that are capturing EEG is necessary. The present disclosure provides a method and system for channel identification using manifolds of an Ear-EEG signal. In the present disclosure, a plurality of manifold features are extracted from a signal received from the wearable ear device. The plurality of manifold features are further classified as EEG and non-EEG channels using an unsupervised clustering model across real-world stimuli in the wearable ear device."
