Publication number: 20240015088Abstract: A CMTS may instruct one or more cable modems to transmit an upstream test signal with a particular preamble (and or any other type of signature) in the upstream transmission bandwidth. The preamble may be within a significant band of the upstream transmission bandwidth. A leakage detection device may be brought in the vicinity of the cable network to listen for various signals. The leakage detection device may filter received signals to retain the portions thereof within a desired limited band and further filter the band-limited signals to reduce noise, e.g., removing the payload following the preamble. A correlation filter in the leakage detection device may compare the pattern in the band-limited filtered signal with a stored preamble. If there is a match, the leakage detection device may generate an indication that leakage is detected in the upstream transmission.Type: ApplicationFiled: July 11, 2022Publication date: January 11, 2024Applicant: VIAVI SOLUTIONS INC.Inventors: Daniel K. CHAPPELL, Adam D. GRAY, Brett EMSLEY, Loren R. EGGERT

Patent number: 11650266Abstract: Systems and methods for detecting leakage in a cable network system are disclosed. In at least some illustrative embodiments, a system may include a digital tagger operable to generate a digital tag including a chirp signal configured to be placed on a downstream signal path of the cable network system, and a cable network test instrument configured detect the digital tag in wireless signal data received from the cable network system when a point of ingress is presented in the cable network system. The network test instrument may be operable to provide a user-perceptible indication when the digital tag is detected to inform a technician or other user that a flaw in the cable network system is nearby.Type: GrantFiled: August 10, 2021Date of Patent: May 16, 2023Assignee: Viavi Solutions Inc.Inventors: Adam D.

Patent number: 11303509Abstract: Implementation resources are operated in a manner furthering a particular purpose while excluding use of the implementation resources for other purposes. At least some of the implementation resources have capacity that is usable to implement multiple other resources. The capacity of the implementation resources is allocated in a manner that satisfies one or more conditions on the capacity of the implementation resources that is used. Generally, the capacity is allocated in a manner that reduces the likelihood that resources initiated close in time will fail together should underlying implementation resources fail. The implementation resources may be hardware devices that implement virtual computer systems.Type: GrantFiled: July 31, 2017Date of Patent: April 12, 2022Assignee: Amazon Technologies, Inc.Inventors: Marc J. Brooker, Cornelle Christiaan Pretorius Janse Van Rensburg, Abhinav Agrawal, Adam D. Gray, Marvin M. Theimer, Peter N. DeSantis

Patent number: 10901791Abstract: Techniques are described for providing clients with access to functionality for creating, configuring and executing defined workflows that manipulate source data in defined manners, such as under the control of a configurable workflow service that is available to multiple remote clients over one or more public networks. A defined workflow for a client may, for example, include multiple interconnected workflow components that are specified by the client and that each are configured to perform one or more types of data manipulation operations on a specified type of input data. The configurable workflow service may further execute the defined workflow at one or more times and in one or more manners, such as in some situations by provisioning multiple computing nodes provided by the configurable workflow service to each implement at least one of the workflow components for the defined workflow.Type: GrantFiled: April 30, 2019Date of Patent: January 26, 2021Assignee: Amazon Technologies, Inc.Inventors: James P.

Patent number: 9893764Abstract: Apparatus and method are provided for obtaining an upstream signal spectrum as it was during a time of transmission of a received upstream data packet. The apparatus includes an analog-to-digital converter (ADC), a packet detector coupled to ADC, and a spectrum calculation unit coupled to the ADC and the packet detector. In operation, the spectrum calculation unit computes a spectrum of the digitized upstream signal as it was between the start and end times of the first packet. As a result, the obtained spectrum is representative of a condition of the transmission path during transmission of the upstream data packet.Type: GrantFiled: April 26, 2017Date of Patent: February 13, 2018Assignee: VIAVI SOLUTIONS INC.Inventors: Adam D.

Patent number: 9774847Abstract: A dual-port testing apparatus is provided for testing a cable network at two test points. The testing may comprise demodulation of a same data packet at the test points, decoding the data packet, performing spectral analysis of the signal, etc. Testing results may be correlated with one another, both visually and by using pre-defined test metrics comprising a weighted sum of demodulation and decoding parameters such as modulation extinction ratio and a codeword error.Type: GrantFiled: May 20, 2016Date of Patent: September 26, 2017Assignee: VIAVI SOLUTIONS INC.Inventors: Daniel K.
