  • Patent number: 10812120
    Abstract: Indication of an amount of processing performed in detection and removal of ingress noise may be provided. A frequency domain representation of a narrowband region of a digital input signal may be received. The received frequency domain representation of the narrowband region may be compared with a predetermined threshold. Results from the comparison of the received frequency domain representation of the narrowband region with the predetermined threshold may be aggregated. Based on the aggregated results, an indication of an amount of processing performed by an ingress exciser in removing the ingress noise may be provided.

  • Patent number: 10796311
    Abstract: A method and system include receiving a request to initiate a purchase transaction with a payment card product; generating a message to verify an authenticity of a cardholder of the payment card product, wherein the message includes a request for data about a previous transaction executed with the payment card product; receiving, in response to the generated message, input from the cardholder; comparing the input from the cardholder to stored data associated with the previous transaction; and one of confirming the cardholder as a true owner of the payment card product or denying the cardholder as the true owner of the payment card product based on the comparison. Numerous other aspects are provided.

  • Patent number: 7839773
    Abstract: In one embodiment, a first ranging timing description describing at least a duration of time during which a subject cable modem (CM) may burst and a duration of time during which the subject CM and other CMs in a multiple access network are not permitted to burst is translated into a second ranging timing description describing a duration during which a burst from the subject CM is expected to be received by a cable modem termination system (CMTS). The CMTS is conditioned to receive a burst from the subject CM during the duration of time described by the second ranging timing description. A timing offset is determined from at least an actual time a burst from the subject CM is received by the CMTS and the duration of time during which the subject CM and other CMs in the multiple access network are not permitted to burst to produce a determined timing offset. The determined timing offset is reported to compensate for delay in the multiple access network and the subject CM.
