What changed

The USPTO granted Patent US12588859B2 to the Education University of Hong Kong for a system and method for interacting with human brain activities using EEG-fNIRS neurofeedback. The patent, invented by Kin Chung Michael Yeung, includes 12 claims covering an integrated system with EEG electrodes, fNIRS detectors, an information receiver, a computation module, and a report generator. The computation module processes signals from both EEG and fNIRS modalities, calculates score information, selects the minimum score, and discards alternatives to provide a single representative score for a shared target objective.

This is a patent grant notice and does not impose compliance obligations or deadlines on third parties. Companies developing neurofeedback technology or brain-computer interface systems should review this patent to assess potential licensing needs or freedom-to-operate considerations. The patent claims cover specific technical implementations for combining EEG and fNIRS signal processing in neurofeedback applications.

Abstract

An integrated EEG-fNIRS neurofeedback system for interacting with participant's brain activity includes EEG electrodes, fNIRS detectors, at least one information receiver, a computation module, and a report generator. The EEG electrodes collect EEG signals. The fNIRS detectors collect fNIRS signals. The at least one information receiver receives and processes the collected EEG and fNIRS signals. The computation module executes an EEG and fNIRS signal processing pipeline with the EEG electrodes, the fNIRS detectors, and the information receiver. The computation module is further configured to: calculate score information based on received EEG and fNIRS signals; select a minimum score from the calculated score information; and discard an alternative score that is not selected as the minimum score, so as to enable the computation module to choose a single representative score for the shared target objective from both EEG and fNIRS signals. The report generator provides a report of the selection.
