Core Viewpoint - Huawei Technologies Co., Ltd. has recently published a patent application for a "signal processing method and related device" applicable in the field of brain-computer interface (BCI) technology [1] Group 1: Patent Details - The patent involves acquiring a first signal, which is collected from brain tissue, and obtaining downstream feedback signals [1] - The method processes the first signal based on the feedback signal, rather than directly inputting the first signal into a decoding device, ensuring long-term stability in signal encoding and decoding [1] - This approach helps to avoid the degradation of signal encoding and decoding stability due to non-stationarity of the first signal [1]
