Abstract: 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 audio input to identify the background noise portion of the main audio signal. A noise reduction algorithm suppresses the identified background noise in the main audio signal. The one or more reference microphones defining the acoustic perimeter may be included in separate microphone devices placed in proximity to the main desktop phone, microphones within other nearby desktop telephone devices, or a combination of both types of devices.

Abstract: A method includes generating first audio data based on sound detected by a sound sensor at a first time. The method further includes transmitting, via one or more communication interfaces, the first audio data to another device during a communication session based on a determination that the sound sensor is unmuted with respect to the communication session at the first time. The method further includes generating second audio data based on sound detected by the sound sensor at a second time. The method further includes refraining from transmitting the second audio data to the other device during the communication session based on a determination that the sound sensor is muted with respect to the communication session at the second time. The method further includes initiating a natural language processing operation on the second audio data based on detecting a wake phrase in the second audio data.

Abstract: A novel universal bridge (UB) can handle and conduct multimedia multipoint conferences between a plurality of MREs and LEPs without using an MRM, an MCU and a gateway. Further, a UB can be configured to allocate and release resources dynamically according to the current needs of each conferee and the session.

Abstract: A circuit having a dynamically adjustable common mode rejection ratio. The circuit has a high common mode rejection ratio without the need for input transformers. The circuit's ability to adjust the circuit's common mode rejection ratio is enhanced by the circuit's high input impedance. The circuit includes first and second input terminals, and output terminals. A positive leg runs from the first input terminal to the first output terminal, the positive leg including a resistor, and a negative leg runs from an input terminal to an output terminal. The digital signal processor controls a potentiometer on one of the legs to dynamically adjust the common mode rejection ratio of the circuit.

Abstract: A controller has a basic GUI formed of HTML5 and Javascript including elements to control a system as a whole. The controller receives GUI HTML5 and Javascript from each connected hardware module, such as a camera, microphone, lighting controller and the like. The controller adds the received HTML5 and Javascript from each hardware module to the base code and sends the combined GUI to the user. Data is returned from the user to the controller and then forwarded to the proper hardware module.

Abstract: A videoconferencing system has a videoconferencing unit that use portable devices as peripherals for the system. The portable devices obtain near-end audio and send the audio to the videoconferencing unit via a wireless connection. In turn, the videoconferencing unit sends the near-end audio from the loudest portable device along with near-end video to the far-end. The portable devices can control the videoconferencing unit and can initially establish the videoconference by connecting with the far-end and then transferring operations to the videoconferencing unit. To deal with acoustic coupling between the unit's loudspeaker and the portable device's microphone, the unit uses an echo canceller that is compensated for differences in the clocks used in the A/D and D/A converters of the loudspeaker and microphone.

Abstract: A system for matching audio-to-video spatial presence in a teleconference, which includes capturing video stream with a camera of a teleconferencing unit at a local endpoint. The teleconferencing unit has a first end and a second end, and a camera located midway between. The system determines a visual stage based on the video stream, and captures audio using microphones on both sides of the camera. The system determines a sound stage based on the audio captured by the microphones, and matches the sound stage to the visual stage, based on the direction of a sound source relative the parameters of the visual stage. The visual stage and matching sound stage can by output for rendering by one or more devices at a second endpoint.

Abstract: A telepresence system which includes at least one display device and a beacon coupled to the display device. The beacon emits a signal so as to be discoverable by electronic devices nearby such as in a meeting location. The system also includes a receiver-controller coupled to the beacon, the receiver-controller configured to enable such electronic devices to be recognized and to join a collaborative session in which content from one electronic device can be shared with other electronic devices. The receiver-controller can and will share some or all of its functions with one or more of the joined devices simultaneously, if security and identity protocols are satisfied.
