  • Publication number: 20170230167
    Abstract: We disclose an optical receiver for direct detection of an intensity-modulated optical signal, the digital signal processor of which employs a clock-recovery circuit capable of reliably recovering the internal clock of the received optical signal without relying on dispersion-compensation processing even if the signal's eye pattern is substantially closed. In an example embodiment, the clock-recovery circuit comprises a frequency-domain phase detector that operates to determine and track in time the sampling phase using only a subset of the digital spectral components corresponding to the received optical signal. The determined sampling phase is then used to synchronize the digital electrical samples of the received optical signal with the internal clock thereof by way of digital interpolation or through appropriate control of the sampling frequency and phase of the receiver's analog-to-digital converter.

  • Patent number: 9729407
    Abstract: VoIP networks and methods are disclosed for distributing media resources in a VoIP network for providing services. VoIP endpoints, media gateways, and/or other network nodes in the VoIP network report available media resources (i.e., available processing capacity) that are able to provide services, such as providing announcements, DTMF digit collection, etc, to a distributed resource server. The distributed resource server then assigns the available media resources among the VoIP endpoints and/or media gateways to perform services for calls in the VoIP network in order to distribute the tasks of performing services among different nodes of the VoIP network.

  • Patent number: 9727055
    Abstract: Systems and methods for video processing and display are provided. In one aspect, a workstation is configured to determine a position of a remotely controlled vehicle when an image of the surroundings of the vehicle was captured, and to transform the image into a transformed image based on an estimated real-time position of the vehicle. In another aspect, a workstation is configured to identify an image captured prior to the time a remotely controlled vehicle changed its configuration. The workstation estimates a real-time position of the vehicle, and transforms the identified image into a transformed image based on the estimated real-time position of the vehicle, such that the transformed image represents at least a portion of a view of the surroundings of the vehicle at the estimated real-time position after the vehicle changed its configuration.

  • Patent number: 9729361
    Abstract: A fractional delay estimation module estimates a delay of a section of a forward processing path between a first point and a second point. The fractional delay estimation component determines an integer component and a fractional component of a first path delay based on a transform of a first vector inserted into the forward processing path at the first point and based on a transform of a first feedback vector received from a feedback path, determines an integer component and a fractional component of a second path delay in the forward processing path based on a third transform of a third vector inserted into the forward processing path at the second point and based on a fourth transform of a second feedback vector received from the feedback path, and further determines the estimated delay of the section based on a difference between the first and second path delays.

  • Patent number: 9712392
    Abstract: VoIP networks and methods are disclosed for configuring SIP endpoints of VoIP networks. An application server of a VoIP network identifies an endpoint configuration for the SIP endpoints, and generates a configuration command based on the endpoint configuration. The application server formats a SIP message to include the configuration command, and transmits the SIP message to the SIP endpoints. Responsive to receiving the SIP message, the SIP endpoints process the SIP message to identify the configuration command, and set local configuration parameters based on the configuration command.

  • Publication number: 20170201066
    Abstract: We disclose a vertical-cavity surface-emitting laser (VCSEL) whose optical resonator can support multiple transverse resonator modes. The VCSEL has a plurality of electrodes that can apply individually controllable electrical currents to the active semiconductor region of the optical resonator and be configured to excite, e.g., a single selected transverse resonator mode or a desired linear combination of transverse resonator modes. In some embodiments, the VCSEL's optical resonator may have an effective lateral geometric shape that causes the excitable transverse resonator modes to correspond to the waveguide modes of a cylindrical optical fiber.

  • Patent number: 9692513
    Abstract: System and method to extend the upstream data capacity of an HFC CATV system by extending a “shadow” optical fiber network deeper into the various CATV cable neighborhoods, with coax fiber terminals (CFT) spaced roughly according to the distribution of CATV active devices such as RF amplifiers. The CFT can intercept local upstream data from various neighborhood sub-regions and transform this upstream data into upstream optical data, thus relieving upstream data congestion in the 5-42 MHz CATV frequency region. The system can produce an order of magnitude improvement in upstream capability, while maintaining high compatibility with legacy HFC equipment. The CFT may exist in multiple embodiments ranging from low-cost “dumb” CFT to sophisticated CFT that can additionally provide GigE to the home (GTTH) service. Methods to maintain good compatibility with legacy CMTS devices, and methods to utilize DOCSIS MAP data for more efficient data transmission are also discussed.

  • Patent number: 9692612
    Abstract: Distributed CMTS device for a HFC CATV network serving multiple neighborhoods by multiple individual cables, in which at least some and often all of the QAM modulators that provide data for the individual cables are remote QAM modulators ideally located at the fiber nodes. A CCAP set of IP/on-demand data is transmitted to the nodes using an optical fiber, often using digital protocols such as Ethernet protocols. Optionally a basic set of legacy CATV QAM data, transmitted using RF waveforms transposed to optical frequencies, may also be transmitted to the nodes using either the same or different optical fiber. The nodes extract the data specific to each neighborhood, and inject this data into unused cable QAM channels along with any optional legacy CATV QAM waveforms as desired, thus achieving improved data transmission rates through finer granularity. A computerized “virtual shelf” control system for this system is also disclosed.
