Latest Patents

One of Xin Xu's latest patents is titled "Adaptive conferencing pod sidetone compensator connecting to a telephonic device having intermittent sidetone." This invention involves teleconferencing pods equipped with a microphone and loudspeaker for open-air conversations. These pods connect to a separate telephonic device that generates an intermittent sidetone, which can be distracting. The invention includes a sidetone suppressor that mitigates the echo produced by this sidetone and a compensator that detects transitions in the sidetone to prevent echo signals from being generated in the pod. The suppression methods may involve various adaptive controls, including delay factors and coefficients.

Another significant patent is the "Method of capturing constant echo path information in a full duplex speakerphone using default coefficients." This method focuses on optimizing echo cancellation by determining the best times to save default coefficients in an echo canceller. By constantly monitoring the error signal, the method ensures that the default coefficients are updated whenever the current coefficients perform better than the saved ones.
