Title: Innovations of Zhenyong Zhang in Sound Recognition Technology

Introduction

Zhenyong Zhang is a prominent inventor based in San Jose, California, known for his significant contributions to sound recognition technology. With a total of 14 patents to his name, Zhang has developed innovative systems that enhance the way audio signals are processed and recognized.

Latest Patents

One of Zhang's latest patents is titled "Time-based frequency tuning of analog-to-information feature extraction." This invention includes a sound recognition system that utilizes time-dependent analog filtered feature extraction and sequencing. The system features an analog front end (AFE) that receives input analog signals, such as those from a microphone. The invention extracts features from the input signal by measuring attributes like zero crossing events and total energy in filtered versions of the signal, which have different frequency characteristics at various times during the audio event. In one embodiment, a tunable analog filter is controlled to change its frequency characteristics at different times during the event. In another embodiment, multiple analog filters with distinct characteristics filter the input signal in parallel, allowing for the extraction of signal features from each filtered signal. A multiplexer then selects the desired features at different times during the event.
