  • Patent number: 11336586
    Abstract: A method for communicating in real-time to users of a provider of Internet access service, without requiring any installation or set-up by the user, that utilizes the unique identification information automatically provided by the user during communications for identifying the user to provide a fixed identifier which is then communicated to a redirecting device. Messages may then be selectively transmitted to the user. The system is normally transparent to the user, with no modification of its content along the path. Content then may be modified or replaced along the path to the user. For the purposes of establishing a reliable delivery of bulletin messages from providers to their users, the system forces the delivery of specially-composed World Wide Web browser pages to the user, although it is not limited to that type of data.

  • Patent number: 11265031
    Abstract: Systems, methods, and computer program product embodiments are disclosed for removing any fixed frequency interfering signal from an input signal without introducing artifacts that are not part of the original signal of interest. An embodiment operates by using a virtual buffer with a length that matches a length of one cycle of an interfering signal. The embodiment extracts the interfering signal into the virtual buffer. For a sample in the next cycle of the interfering signal that corresponds to a virtual memory location for the virtual buffer, the embodiment can update one or more physical memory locations of the virtual buffer that are in the vicinity of the virtual memory location. This use of virtual buffer can remove any interfering signal without creating the artifacts associated with conventional notch filters.

  • Patent number: 11212394
    Abstract: The transmit power level of a transceiver coupled to a digital subscriber line (DSL) line is reduced from a first transmit power level sufficient for the transceiver to transmit data on the DSL line at a first bit rate to a second transmit power level below the first transmit power level sufficient for the transceiver to transmit data on the DSL line at a second bit rate that is lower than the first bit rate. The reduction in transmit power is limited so that the change does not induce time-varying crosstalk sufficient to destabilize a nearby DSL line. While the transmit power level of the transceiver is reduced to the second transmit power level, the transceiver is suspended from transmitting data on the DSL line for repeated periods of time. Suspending the data transmission is controlled to avoid further time-varying crosstalk sufficient to destabilize the nearby DSL line.

  • Patent number: 11005577
    Abstract: Circuits and systems may be operable to provide improved wireless networking performance in the presence of a high speed wired interface. Filter circuits may be applied to wired interface leads to suppress frequency content that may interfere with wireless home networking. High speed digital wired interface systems on a chip may similarly be altered to suppress interfering frequency content before it leaves the chip. Systems with reduced radiated energy from wired interface circuits in frequencies of interest to wireless networking have improved wireless range and throughput characteristics.

  • Patent number: 11005618
    Abstract: Determining when to provide a Proactive Grant Service (PGS) scheduling grant. A plurality of PGS grants are issued to a cable modem (CM). The PGS grants that were utilized by the CM are monitored as well as those PGS grants that were not utilized by the CM. A compromise PGS grants pattern for that CM is generated based on the observations of which PGS grants the CM utilized and which PGS grants the CM did not utilize. The compromise PGS grants pattern for that CM optimizes a projected experienced latency and jitter for particular data flows of the CM verses a projected wasted upstream capacity.
