Title: Innovations of Beng Huat Chua

Introduction

Beng Huat Chua is a notable inventor based in Singapore, known for his contributions to the field of digital communication and audio technology. With a total of 8 patents, he has made significant advancements that enhance the performance and efficiency of audio systems.

Latest Patents

One of his latest patents is the Voice Energy Detection (VED) system. This innovative system utilizes a VED circuit along with a capture buffer to improve performance and reduce power dissipation. By assigning a VED to each microphone, the system combines the outputs of multiple VEDs to enhance detection probability and minimize false alarms. The dynamic selection of VED circuits based on background energy and detection performance further optimizes the post-detection signal-to-noise ratio. Additionally, a digital VED algorithm adjusts the oversampling ratio (OSR) and passband bandwidth according to the loudness of background noise and desired signal levels. This ensures efficient power usage while maintaining high-quality audio processing.

Another significant patent is the Digital Wireless Audio Communication System employing Time Diversity. This system effectively transfers digital data over a fixed frequency channel in the presence of interference. It includes a time diversity generation circuit that compresses data frames and replicates them for transmission. The communication receiver is equipped with a time diversity data recovery circuit that buffers the received data frames and evaluates their integrity. If any data frame is compromised, the system utilizes the duplicate to recover the lost information.
