Acoustic perimeter for reducing noise transmitted by a communication device in an open-plan environment
Granted: December 1, 2020
Patent Number:
10856077
The amount of far-field noise transmitted by a primary communication device in an open-plan office environment is reduced by defining an acoustic perimeter of reference microphones around the primary device. Reference microphones generate a reference audio input including far-field noise in the proximity of the primary device. The primary device generates a main audio input including the voice of the primary speaker as well as background noise. Reference audio input is compared to main…

Long-term reference for error recovery without back channel
Granted: October 27, 2020
Patent Number:
10819976
A video encoding method eliminates the need for back channel feedback by using long-term reference frames for recovering data transmission errors. A videoconferencing endpoint captures image data and designates a first frame as a long term reference (LTR) frame. Subsequent intra frames us the LTR frame for reference. When a new LTR frame is designated, subsequent frames use the newly designated LTR frame for reference only after it is determined that the newly designated LTR frame is…
Gradient micro-electro-mechanical (MEMS) microphone assembly
Granted: October 27, 2020
Patent Number:
10820074
MEMS microphone assembly which is formed by the combination of front and rear single piece boots, which are configured to mate, and a MEMS microphone. The front boot includes two ports for receiving sound waves which are provided to ports of the MEMS microphone. The front boot includes two collars to form the ports and which are used to align the MEMS microphone assembly in a housing containing the MEMS microphone assembly. Acoustic tubes transfer the sound waves from the ports to the…
Minimizing echo due to speaker-to-microphone coupling changes in an acoustic echo canceler
Granted: October 27, 2020
Patent Number:
10819857
An endpoint receives audio from a remote endpoint. A first signal corresponding to the audio is received at an adaptive filter, and a filtered signal is generated. First audio is emitted at a loudspeaker based on the first signal. A microphone collects second audio which is based on the first audio. The microphone signal emits a signal based on the second audio. The filtered signal is subtracted from microphone signal to generate an adapted signal, the adapted signal having an energy…
