Latest Patents

Rong Hu's latest patents showcase his innovative approach to technology. One notable patent is for a system designed for **dereverberation and noise reduction**, which enhances audio processing during communication sessions. This system employs a deep neural network (DNN) to perform speech enhancement, positioned after an Acoustic Echo Cancellation (AEC) component. The DNN processes isolated audio data from the AEC to effectively mitigate both additive noise and reverberation. Moreover, it includes configurations for acoustic interference cancellation that eliminate the need for residual echo suppression processing by jointly handling additive noise, reverberation, and residual echo. This system utilizes complex-valued spectrograms to optimize audio quality during communications.

Another significant patent by Rong Hu is for an **integrated haptic system**, which features a digital signal processor (DSP) and an amplifier integrated within the system. This innovative design is capable of responding to force sensor signals to generate haptic playback signals. The amplifier then drives a vibrational actuator, enhancing the user's tactile experience by providing responsive feedback to applied forces.
