Abstract: Presented herein are techniques for controlling the level of ultrasound pairing signals generated in a teleconferencing environment. The levels of ultrasound pairing signals transmitted in a meeting room are adjusted automatically based on the ultrasound signal levels received at one or more of the sound receiving devices that can communicate with a teleconferencing endpoint in the meeting room.

Abstract: A processing system can include a processor that includes circuitry. The circuitry can be configured to: receive far-end and near-end audio signals; detect silence events and voice activities from the audio signals; determine whether an audio event in the audio signals is an interference event or a speaker event based on the detected silence events and voice activities, and further based on localized acoustic source data and faces or motion detected from an image; and generate a mute or unmute indication based on whether the audio event is the interference event or the speaker event. The system can include a near-end microphone array to output the near-end audio signals, one or more far-end microphones to output the far-end audio signals, and one or more cameras to capture the image of the environment.

Abstract: Techniques are presented herein for a server to automatically determine the locations of collaboration endpoints and user devices throughout a building, and then provide the user devices with directions to the endpoints. The server collects air pressure and GPS readings from the user devices over a period of time. The readings may be collected from user devices that are paired or unpaired with endpoints at the time of the readings. Over a period of time, the plurality of readings may be used by the server to calculate user device offsets, endpoint offsets, floor level offsets, and endpoint relative orientations within the building. The server may then, in response to a notification of an upcoming meeting, provide the user device with directions to the meeting based on the collected readings.
