  • Patent number: 10432543
    Abstract: Various embodiments of the present technology generally relate to systems and methods for packet-based communications. More specifically, some embodiments provide cause a machine (e.g., client device, data center, collaboration service, etc.) to receive data packets from a network. The data packets can include payloads that represent encoded data from a real-time communication between multiple devices and can be copied into multiple jitter buffers. The multiple jitter buffers can include a first jitter buffer having a first size and a second jitter buffer having a second size that is larger than the first size of the first jitter buffer. In some embodiments, the machine can decode the data packets or payloads from the multiple jitter buffers to create at least a first output signal from first jitter buffer and a second output signal from the second jitter buffer.

  • Publication number: 20190259404
    Abstract: An audio stream is encoded for transmission to a receiving device via a communications channel. The to-be transmitted audio stream is received at an audio encoder executed on a processor. The processor has an amount of available processing resources. An available bandwidth of the communications channel is determined. Based on the determined bandwidth, a portion of the available processing resources is allocated to the audio encoder. The allocated portion is greater if the determined bandwidth is below a bandwidth threshold. The audio encoder encodes the audio stream using the allocated portion of processing resources, and transmits the encoded audio stream to the receiving device via the communications channel.

  • Publication number: 20190207845
    Abstract: Disclosed are systems and methods for scaling Massively Scalable Data Center (MSDC) networks with a large number of end-point tunnels utilizing Equal-cost multi-path routing (ECMP). The systems and methods can use the NO-OP label operations to maintain single ECMP objects to switch a set of segment routing tunnels that share the same ECMP links. The forwarding engine can determine the use of the NO-OP label operation and update a received packet to enable the use of the single ECMP objects of the set of segment routing tunnels.

  • Publication number: 20190190112
    Abstract: An electromagnetic coupler includes a first transmission line connecting an input port to an output port and a second transmission line adjacent the first transmission line and connecting a coupled port to an isolation port. The electromagnetic coupler provides a coupled signal at the coupled port, which is representative of an input signal at the input port. The amplitude of the coupled signal is related to the amplitude of the input signal by a coupling factor. A tuning element is electromagnetically coupled to at least one of the first and second transmission lines. An adjustable impedance is coupled between the tuning element and a reference node. Varying resistive impedance components causes an adjustment to the coupling factor and reactive impedance components provide frequency filtering effects.

  • Patent number: 10240451
    Abstract: A tomographic imaging apparatus utilizes Compton backscattering to evaluate cement behind the casing. The imaging apparatus includes a slant-hole or pin-hole collimator coupled to a series of detectors in order to count the number of photons that backscatter off from the cement. The number of backscattered photons is proportional to the density of the cement behind the casing. Using the photon count, an image processing unit of the imaging apparatus generates a 2D or 3D tomographic image of the borehole.

  • Patent number: 10147415
    Abstract: Content is received at a receiving equipment from a transmitting user terminal over a network in a communication session between a transmitting user and a receiving user. The received content comprises audio data representing speech spoken by a voice of the transmitting user, and further comprises text data generated from speech spoken by the voice of the transmitting user during the communication session. At the receiving equipment, at least a portion of the received text data is converted to artificially-generated audible speech based on a model of the transmitting user's voice stored at the receiving equipment (and in embodiments in dependence on the receive audio quality). The received audio data and the artificially-generated speech are supplied to be played out to the receiving user through one or more speakers.
