Latest Patents

Peng Zhou holds a patent for a divisive normalization method, device, audio feature extractor, and a chip. This invention aims to enhance the robustness against variations in background noise. The proposed per-channel divisive normalization method involves obtaining an average number of input spikes over an averaging window using a low-pass filter to produce a threshold parameter. It then decides whether to enable an integrate-and-fire (IAF) counter counting over a clock period of a divisive normalization module. When the count value of the IAF counter reaches the threshold, it resets the IAF counter and produces a single spike at the output. Compared to prior art, this method does not require any Linear Feedback Shift Register (LFSR) and is easier to implement. It features a simpler structure, higher accuracy, better statistical performance, lower cost, and reduced power consumption.
