Real-time Media Analysis Architecture & Protocol 9/18/23
Value Proposition: The future of devices requiring real-time application interaction will be enabled by an architecture based on a consistent set of protocols, high speed, low latency connections, and edge caching. This innovation positions the cable industry to enable and realize this future for these devices and users by building a standardized set of protocols and architecture for any application to work with any device over a highspeed network. An architecture such as this will allow for off-loading processing from the devices allowing device manufacturers to create innovative devices in the market. This will increase competition and ultimately benefit the subscribers. In addition, this architecture opens a wide range of new business strategies and opportunities for revenue generation to cable operators by creating the ability to sell preferences to apps through an innovative media analysis server and app cache.
Extensions to Network Grafting 9/18/23
Detect signal level changes to indicate that a switch has occurred and worked. Likewise, monitor for a drop or raise in profile initiated. Depending on which CMs change and how, which experienced outage before the switch and which just switched, one can localize the fault.
Detecting Nonlinear Distortion In Cable Spectrum Using a CM or SDR and Method and System to Find Distance to a PIM (Passive Intermod) Diode in Wiring 9/18/23
Sources of CPD can be discovered by their characteristic 2nd order distortion products which cable amplifiers do not normally produce. Previously, a wide block of frequencies was captured in the time domain and analyzed by DSP (digital signal processing) to determine if 2nd order or 3rd order nonlinear distortion was present in a vacant frequency band. This alternate method is for a two-input software defined radios (SDR) to capture on one input the portions of the downstream signal where some distortion products are created and on the second input a resulting distorted spectrum. The two captured signals are processed together to determine if harmonics of a lower-frequency source signal are contained in a higher-frequency target signal. Distance to CPD source can be determined using a cross correlation between the distorted signal giving time difference, if any. A mathematically produced “measured” distortion signal created by squaring or cubing the distortion-producing waveform and this is processed with a captured distortion-producing signal.
MAC NE in n:N Failure Protection 9/13/23
All forms of MAC NE (RMD, RMC, RPD) could be designed and configured to allow full pass through or to act as a PHY repeater if instructed to do so. By specifying messaging to the MAC NEs from the MAC Manager or Core, and/or a peer to peer signaling method between MAC NEs, a system of n redundant spares protecting N actives can be established. Then, if there is failure of one active NE, there is a close enough backup that can serve to replace it, if the failed NE can fail with pass through. In simplest forms, they can be set in 1:1 protection; but there may be situations where 1:N or even n:N are possible.
Holographics Over 10G 9/13/23
Depth-based media is an emerging market for users and enterprise that has recently witnessed a sharp uptick in growth and investment. With the rising demand for remote communication in virtual spaces, automation in transportation, maintenance, supply chain, and visualization techniques in healthcare, defense and simulation industry, startups and large companies are competing in this nascent market with the launch of fixed and wearable display units, free and propriety immersive content, developer tools, and a host of ecosystems to integrate, co-ordinate accelerating development among software professionals and industry experts. Despite growing support, challenges to content generation and transmission include developing an interchange format to support compatibility and an evolved network infrastructure to satisfy bandwidth and latency requirements to reliably and securely deliver immersive content.
Informative CM Display 7/18/23
Expand and perhaps standardize the display (like a cheap calculator crystal display) on a CM to indicate a message from the service provider. Messages could include known outages, planned maintenance, details of cause of issues, expected repair time, suggestions to check in home wiring, when and who to call, billing reminders and details, even special offers if opted into. The messages could be indicated by a simple upstream tone during an outage or planned maintenance, through internal troubleshooting capabilities added to the CM (Murphy), messages from the CMTS via MIBS or other signaling mechanisms, or a combination.
Wi-Fi Adaptative 5/6 GHZ Band Selection 7/18/23
This idea proposes a new mechanism to dynamically select the best band between the 5 GHz and the 6 GHz bands.A process running on a Wi-Fi gateway will record what clients support the 5 GHz and/or the 6 GHz band, the behavior of each client (traffic type and traffic pattern throughout the day and the week) and the airtime utilization of the 2.4 and 5 GHz channels. Once the client behaviors are learned, the AP can dynamically select the 5 GHz or 6 GHz band for the best QoE across all users.
Method of Detecting End-user Private Data Leakage 7/18/23
End-users may be able to specify their privacy preferences (e.g., CableLabs project: User-Centric Privacy – D5102) but figuring out if an entity is violating those preferences is extremely difficult. This is challenging because traffic between and end-user’s computer or mobile device is encrypted at the application-layer (e.g., HTTP (SSL)) and tracking what private information is transmitted to which application provider.
A Federated Learning Appliance for Constrained Devices 7/18/23
We propose a novel federated learning appliance that can plug into any embedded device with a USB serial port to perform custom federated machine learning with minimal coding and configuration required.
Explainable AI for PNM 7/18/23
AI and ML solutions experience friction with adoption in part due to their lack of explainability. While there is much research and development to add explainability to these solutions, they mostly rationalize a black box algorithm, or suggest monitoring of the inner model components, neglecting the value of the input space as a form of explainability. Further, for AI and ML solutions applied to PNM, including our CableLabs anomaly detector (AD), a black box explainer would be redundant and with questionable value, while monitoring the inner model components gets complicated and does not explain well to the user, which does not provide confidence and reduce friction in acceptance of the decision provided by the AI or ML.
Intelligent Bandwidth Allocation in Access Network by Using Machine Learning for Latency Management 7/18/23
This disclosure describes a novel method for intelligent bandwidth allocation in PON by using machine learning for latency management. The specific method uses reinforcement learning scheme to proactive update the bandwidth allocation policy to control or manage the latency for specific users. The proposed method uses the traffic information as well as network parameters as the State input to the core control unit Agent. The Agent updates the bandwidth allocation policy accordingly, which will be the output Actions to the OLT in PON. These Actions may include updates of the network bandwidth allocation algorithms, adjusting ONU priorities or changing the bandwidth allocation parameters and so on. As a result, the PON will measure the network performance such as latency, throughput or efficiency and return these results to the Agent as the Reward feedbacks. The Reward can be positive or negative based on the results. The training process is based upon the input of the Rewards, and the reinforcement learning algorithms will decide to reward or punish the model based on its output Actions.
Orthogonal OFDM Subcarriers Between DOCSIS and LTE/5g Networks 7/18/23
DOCSIS and mobile networks share a large portion or spectrum that generate interference for each other if there is a leakage point in a cable plant. DOCSIS 3.1 uses 25 or 50 kHz subcarrier spacing while LTE uses 15 kHz subcarrier spacing. If DOCSIS subcarrier spacing could be adjusted to 15 or 30 kHz, along with synchronization between DOCSIS and mobile networks, the mutual interference could be reduced by orthogonality of OFDM.
Frequency Domain Equalization Using Overlapped Fourier Transforms 7/18/23
A linearly distorted signal can be equalized in the frequency domain using a single complex multiply for each component subcarrier frequency. This method is now used for deghosting received multicarrier signals, such as OFDM (orthogonal frequency division multiplex) and OFDMA (orthogonal frequency division multiple access) with cyclic prefixes (CP), and on single carrier signals such as SC-FDMA (single carrier frequency division multiple access), also employing a cyclic prefix. However, by using an overlapped Fourier transform, the requirement for an embedded cyclic prefix can be eliminated, and a pseudo-prefix can be created in an overlapped portion of a Fourier transform. The overlapped time portion is later discarded. This improved equalization method can be used for any type of modulated or baseband signal. The advantages of FD (frequency domain) equalization are lower transmission time overhead from the cyclic prefix removal, and improved computational efficiency in the frequency domain. The computational efficiency is improved relative to a FIR (finite impulse response) filter when the signal’s bandwidth is wide and the echo is relatively long, because FIR filter structures can become very long with many taps. If employed for a burst-type signal, quiet time can be used for the pseudo-CP.
Network Access Virtual Experience Device Acceleration (NAVEDA) 7/18/23
Access virtual device acceleration – for gamers or anyone running applications that do not perform well on their edge devices, enable an edge application to know the device, assess its capabilities toward a use case (based on past experience from this and potentially other users, or based on tests or manufacturers (hw, sw) recommendations or service level) and determine when it is lacking to enable cloud or neighbor compute capabilities to step in and improve the service.
Software Method to Prevent Connected Device Service Theft 6/6/23
Software solution to prevent connected device service theft.
Methods To Prevent Connected Device Service Theft 6/6/23
Cable modems may be stolen in a variety of ways. While DOCSIS prevents unauthorized modems from accessing the network, iterations of DOCSIS before DOCSIS 4.0 do not prevent modems from accessing networks of other operators. If a given operator chooses to do so, they do not have to pay the non-recurring costs for CMs (and neither do their customers). This puts operators with more sustainable business models at a competitive disadvantage, at least in the short term.
This invention addresses this by providing a variety of mechanisms implementable in software to prevent a modem from registering, on-boarding, or connecting to a 3rd party’s network.
Enhanced Wireless Emergency Mobile Alert System 6/6/23
The WEA is a good mechanism to broadcast emergency alerts. Enhancements to make this system more effective, reliable, integrated and flexible will significantly speed up the delivery of potentially critical and life-saving information and response.
Since the alerts are broadcast messages, the UE may receive the paging information with the ETWS indication but the user may be away from the phone or the Mobile phones can be switched off (at night), or not be heard in a noisy environment or be in silent mode or do not disturb mode or have notifications turned off. Even if the User receives the alert, there is NO indication/acknowledgement to the first responders/disaster relief agency that the user received the alert message. An acknowledgement can significantly help improve the search and rescue operations and the response of the first responder’s team.
Datalyft – System and Method for Sharing Network Data
Bandwitdth With a Service 6/6/23
Network access convergence technologies created an opportunity to provide better user experience to end customers. A data sharing service platform built on converged access will allow a customer device to share network bandwidth among the end customers. This allows a true ubiquitous network connectivity and experience to end customers.
Create a simple protocol to allow bootstrapping of telemetry in support of installation and troubleshooting of network devices, or devices that are not normally networked, or sensors, either as a one to one (network or telemetry device to reader) or as part of an ad-hoc sensor network, etc.
Method to Support Multi-service, Multi-datalink Box 6/6/23
An aggregation method is provided for multiple disparate access network data communications systems collocated in a shared enclosure. These multiple disparate access network data communications systems have traditionally used different protocols for communications and this method proposes a common network system so these disparate technologies can be operated in a common fashion.
DH Group Based 2nd Factor Authentication for Access Networks 5/15/23
Identities and Cryptography are always evolving. To manage uncertainty, one of the possible option for Access Network is to deploy 2nd Factor Authentication. When combined with identities (e.g., in the form of certificates or otherwise verifiable format), the use of a 2FA together with a trusted source of time can lower the risk of device cloning and possible weakness in the public-key algorithms used.
OCSP and CRL Proxy Signer 5/15/23
In this invention, the CRL and OCSP Proxy uses a special certificate that allows it to provide CRLs and OCSP responses for any (or well-identified) PKIS. The produced responses can override the revocation status from the original CA for NetOps purposes (e.g., OCSP not reachable, Ignore of Revocation Status, etc.)
Frictionless Self Install 5/15/23
This document captures in summary the findings, decisions, and choices made by the Frictionless Self-Install Working Group (FSI-WG) at CableLabs, exploring solutions to the key problems that cause friction in the self-installation process.
This Working Group (WG) brainstormed the major problems, and then the potential areas to explore for technology development, trialing, and research. As of the time this report is released, the group has explored many topics in three main areas: radio frequency (RF) detection, frictionless gateway, and avoiding RF. Each area is briefly explained, then the area is broken down into subtopics and specific solutions. Some additional areas were looked at too. Some solutions are under investigation still, some are tabled until the timing is more appropriate, and others are decided to not pursue further.
Networked Defense Sensors 5/15/23
This is a call to develop small sensors that can detect the use of drones in the area. By creating small sensors that can be on the communication network and complimentary sensors that can connect to the power network, we have redundant capabilities to sense when a drone is in the area, and thus can sound alarms, track information for post attach analysis, and enable fast reaction.
Rapid Coax Cutover 5/15/23
Rapid tap connector for cutover maintenance to reduce outage time. Develop a modular, snap cover, sealed tap that allows rapid cutover to new hardline and maybe taps too. This tap can be made a part of existing taps, amplifiers, nodes, or anywhere that coax needs to connect.
Method for Determining Optimal Wi-Fi Extender Placement 5/15/23
A method for comparing relevant KPIs to determine optimal Wi-Fi extender placement. By capturing the median, non-control MCS rates on the fronthaul and backhaul, it is possible to compare the values and determine if the extender needs to move closer to or further away from the gateway. The end goal is to have equally “good” links on every hop, as the overall throughput of the system will be limited to the MCS of the “worst” link.
Software to Make a Software Defined Radio (SDR) Into a Vector Network Analyzer (VNA) 3/20/23
This idea is to use a SDR as the RF engine to power a VNA. Attached with this disclosure, you will also find reading material and slides on conventional VNAs and S-parameters.
Improving Wireless MIMO With a Dispersive Signal Gathering “Lens” or Reflector 3/20/23
With wireless MIMO spatial diversity, having more potential signal paths with spatial diversity means that a space can support more information transfer by using more signal streams, or RF paths. A signal interfering with other signals at a receive antenna element is actually a desired property. This is because the signals are mathematically separated by performing an inverse matrix comprised of complex transmission coefficient elements, assuming an inverse matrix can be computed. If the inverse solution cannot be computed, a matrix is singular. This idea is to make a radio-wave gathering parabolic lens to produce a large effective aperture and then locate a multi-element phased array at a point which is moved slightly from the focal point. This “blurring” causes spatially diverse signals to overlap. Blurring can also be enhanced by making the surface of the parabolic reflector slightly irregular.
Method for Mac Address Uniqueness Checking via Hierarchical Ranges 3/20/23
Many protocols use MAC addresses as identifiers for devices – devices with different MAC addresses are considered separate entities. In the PKI world 0, CAs may be required to check for uniqueness of values – i.e., checking if a MAC address was already used in a different certificate. These checks can take quite some time because of the large dimension of the search space (48-bits). This invention reduces the lookup procedures requirements by leveraging the concept of constrained ranges of addresses.
Predictive Wi-Fi Behavior in NR-U Environments 3/20/23
Wi-Fi operation in unlicensed spectra will require to coexist with NR-U access technology in the 5/6 GHz bands.
While NR-U adopted a number of measures to coexist with 802.11ac/ax nodes, this coexistence may not be optimal. The implementation of a single ED threshold will drive to a more aggressive NR-U behavior towards Wi-Fi.
This solution addresses an adaptive Wi-Fi behavior implemented intended to increase the WiFi air time access to 50% (or other ratios) when in the presence of coexistent NR-U traffic.
Automatic Certificate Revocation Process With Service Assurance Notification 3/20/23
When a PKI certificate is revoked, impacted subscribers are unable to connect to peers or servers. IT or service provider staff should be made aware of this circumstance so the device can be corrected and service disruption is minimized. Furthermore, to the degree possible, automation of the revocation process can be supported in most circumstances. This invention outlines a process for automatic revocation processing with alerts to support service assurance.
Data Definition and Procedures to Verify Compliance With Certificate Templates 3/20/23
In many ecosystems, because the flexibility provided by digital certificates, the contents of digital certificates need to be regulated to provide interoperability within the deployment environment. Today, no standard exist that provide the required data definitions and procedures to (a) describe a profile (or template) for a certificate, and (b) to validate the compliance of a certificate to a particular profile. This invention addresses this problem by providing a solution to both aspects of certificateprofile validation.
IoT Certificates Registration For Cloud Providers 3/20/23
This method allows the Certificate Service Provider to securely register the certificates and enable them for usage under the customer’s account without exposing the SubCA’s authentication token in the customer’s account directly.
Enable Wi-fi Device Identity With Mac Randomization Enabled
A solution that addresses all network types, including open networks, that in the AP request for the unique STA MAC address, the AP would generate a unique key pair and provide the public key to the STA. The STA then encrypts the unique MAC address with the public key and then returns the encrypted unique MAC address. Since over an open
network monitoring can see happen, the encrypted unique MAC address string is exposed and would not change if the public key remains the same. To overcome this the AP would randomly update the key pair thus resulting in a differing encrypted unique MAC address string being sent.
Methods Of Coupling Hollow-core Fiber With Integrated Photonics For Optical Networks 3/20/23
In the last decades, great progresses have been made to the integration of optical components on a single chip, also known as photonic integration circuit (PIC). However, optical coupling between PIC chip and optical fiber components is still relatively challenging, due to the large size and optical mode mismatch between the optical fibers and the integrated optical waveguides. Coupling light from HCF, a special designed optical fiber with large mode area, into the integrated waveguides on PICs can be more challenging. In this invention, we proposed multiple spot size converter (SSC) designs targeting low-loss optical coupling between HCFs and PIC waveguides, including both edge and vertical coupling configurations.
Using DOCSIS Downstream Codewords for a Quality of Service/Outage Indicator 1/24/23
DOCSIS 3.0 downstream carriers are 6MHz wide in the US and deliver data codewords at a constant rate. There are MIBs, listed in background, that report unerrored, uncorrectable, and correctable codewords. If those numbers are read, timestamped, and summed, a delta calculation can be made between two time intervals. If the delta total number of codewords is not as expected, an outage percentage in the delta time interval can be calculated. Note this may have occurred on a CM because of power cycling. If the uncorrectable to total codewords ratio is calculated, another predictor can be made about downstream signal quality.
Novel AI-based Framework for Balancing Traffic Demand and Service Processes in Unlicensed Bands 1/24/23
This idea proposes methods for balancing traffic demand and service processes for systems operating in unlicensed bands. Unlicensed channels are shared opportunistically by many heterogeneous systems, prohibiting them from providing guaranteed QoS service. We introduce an artificial intelligence (AI)-based framework for classifying and predicting future traffic demand and service processes as well as controlling channel access parameters to meet QoS requirements. We characterize the traffic demand process based on traffic streaming statistics and characterize the traffic service process based on buffer occupancy and queue dynamics. Predictions of future streaming statistics and buffer occupancy dynamics are leveraged to control various channel access parameters and provision various QoS applications and/or meet a harmonious cross-technology coexistence among systems sharing unlicensed bands.
Methods for Resource Reclamation in Unlicensed Mobile Wi-Fi 1/24/23
In the associated invention (described in other invention disclosures and patent filings), rather than associating with a physical piece of hardware, identified by its MAC address, the Wi-Fi client associates with a virtual AP identified by a logical MAC address or Basic Service Set Identifier (BSSID). In order to perform this operation, the WTP hardware or software needs to support multiple BSSIDs, so it can dynamically instantiate a Service Set Identifier (SSID) specific to the client device.
Cable Plant RF Level Verification 1/24/23
In thinking about RF Level verification impairments and problems, we are able to bring to the table solution ideas.
Secure Device Identification 1/24/23
This invention is the outcome of the use of randomized MAC Address starting to be used within Wi-Fi. This move to use MAC Address randomization has trigger a lot of concern of how current systems that relay on the device’s MAC Address for various functions/features.
In thinking about the issue and the solution this solution it occurred that it could be used for the DOCSIS CMs, thus the expansion from just association that is used in the Wi-Fi realm to include registration as well. Then the topic of the DHCP issue came to mind and this continued to how is could be applied to DHCP to prevent IP pool exhaustion

From Barter to Currency – Creating Transparency in the Market for Personal Data 1/24/23
Automatic Traffic Smoothing for Low Latency (ATSLL) 1/24/23
The invention here is to automatically identify this type of traffic flow and apply smoothing to the rate of packets before they hit the cable modem. Since the overall data rate might only be 1Mbps, far below the allowable 5Mbps default congestion rate of Low Latency DOCSIS, this video data should be able to be delivered via the low latency queue without any of the packets being redirected to the classic queue.
Revocation of Compromised SIM Secrets via OCSP Responses and CRLs 1/24/23

Easy Wi-Fi QoE Framework 1/24/23
The Framework provides a comprehensive set of tools to assess the user Quality of Experience (QoE) and assist the user and ISP to enhance the QoE. It also includes a set of to defined the number of Mesh AP needed in a home and to best position the Mesh APs.
Temporary High Priority Access Based on Geographical Location and Time of Day 1/24/23
Access Class Barring (ACB) is a congestion control mechanism designed for limiting the number of simultaneous access attempts from certain UEs. The amin purpose of ACB is to redistribute the access request of UEs over time to reduce the number of access requests per Random Access Opportunity (RAO) window. This helps avoid massive-synchronized access requests to RACH. In order to implement the above, all UEs are assigned to 16 access classes (AC) from 0 to 15, which is stored in the UE’s SIM/USIM information (EF_ACC field in the USIM).
AR Assisted AP Placement 1/24/23
Use AR to overlay a channel-specific antenna pattern on an access point (AP) in order to guide installation. The AR device will capture the channel and band in-use by the AP and apply the correct pattern. Additionally, the user can select any channel or band in order to compare performance and coverage.
Multi-use Method and System for Capturing PNM Data Interpretation ExpertiseGridmetrics/EMP – Space Weather – Magnetic Pulse Sensor 1/24/23
Anomaly detectors need training data, which means it has to be tagged by experts. But the experts in this case don’t always agree on the impairment classifications. We developed a solution that allows groups to tag impairments in data in a group, thus learning together. But also, individuals can take the tool and data to tag on their own. This allows gage capability analysis to be done on individuals, group expert agreement on several examples, and thus the ability to confidently train others, train anomaly detectors (usually machine learning methods), and form a reference database for other purposes. By extending to collect information about the likely causes too, including failure modes, effects, and criticality, we extract more useful information at the same time for more capabilities, automation, and discovery.
Method for Extender Placement in Homes Using Smartphone App 1/24/23
Placing wireless backhauled extenders in the home is difficult, as finding a good location that provides coverage desired while not creating an additional wireless bottleneck is not straightforward nor intuitive.

A framework of APIs, processes, information models, and data models that provide a path to providing holistic patient and outcome centric care experiences. The framework provides a specification to implement a centralized or distributed architecture for a multi- stakeholder health care delivery system.
Gridmetrics/EMP – Space Weather – Magnetic Pulse Sensor 1/24/23
Following development of the Joint Strategy, both DOE and EPRI committed to developing separate, but coordinated, Action Plans that would implement the five strategic goals. EPRI’s plan focused on those actions that industry would undertake to mitigate EMP risks; DOE’s plan (this Action Plan) delineates the steps that DOE will take to address EMP risks. Although the two Action Plans were developed independently, DOE and EPRI collaborated closely to ensure the plans complement one andother and avoid duplication effort.
Method for Visualizing Media Usage 6/28/2016

Garage sale (location and items) advertisement through Community Wi-Fi networks 6/28/2016
Many homes have operator-managed Wi-Fi, which, is primarily used to provide connectivity. This innovation disclosure defines a system and method for operators to use community Wi-Fi network to advertise garage sale items as people walk or drive by a house.
Security Camera Activation Method 6/28/2016
Security cameras in the homes are common place today. Many of these activate independently without any coordination with home networks or other cameras nearby after detecting motion. In addition, a subset of these cameras also have in-built motor to change the angle of view of the camera. The present idea contemplates a coordination between the security cameras and home Wi-Fi network to allow proactive (in some cases before motion detection) filming by the camera. Most people have phones on them, which in many cases include Wi-Fi and Bluetooth. In the situation where an unknown person (carrying a device with MAC address not know to the AP) approaches the home, the AP in the home detects this and inform the appropriate camera to start filming. Based on the granularity of the location information available to the AP, it can also instruct the camera to change the angle and purview of filming. Many homes have multiple APs, the APs can coordinate between each other to get an understanding of the location and direction of the subject client.
Use of Flooring Sensors to Determine Activity and Location 6/28/2016
Obtaining the specific location where individuals are within an environment (home/office/hospital/elderly care facility) as well as activity tracking within that locale could be communicated to systems designed to facilitate the operation of services within that locale or to alert based on activity or inactivity. This would be accomplished by laying a special substrate (in tiles or rolled substrate) under carpeting or hardwood floors.
Personalized QoS 9/15/2015
Network policies for things such as QoS (when used) are not individualized. Today, operators provision similar policies on all residential gateways without any regard to individual preferences. Thanks to social networks such as Facebook, in the last decade or so, a lot of data on individual preference is publicly available and many companies (e.g. Netflix, amazon) are using it to make all kinds of recommendations. In this disclosure, I propose operators use of publicly available data about individual to assign customized network policies per subscriber.
PNM Grouping Algorithm Based on Tap Subtraction 9/15/2015
Summary: Process two sets of equalization coefficients by subtracting taps. Then restore the main tap in the difference. A decrease in a MTR (main tap ratio, the ratio of energy in the main tap to all other taps combined) relative to the minuend coefficients or the subtrahend coefficients indicates a good match.
Gestures for mosaic window management 9/15/2015
Summary: This invention provides a set of gestures that allow you to subdivide a main window into an arbitrary set of sub-windows that completely cover the area of the main window. The process divides the main window into a set of rows or columns and continues by subdividing these rows/columns until the user achieves the window layout they desire.
Device for determining presence of cable service on a jack 9/15/2015
Summary: Our device makes it easy for a customer to tell whether cable service is available on a jack. We attach a cable line to an amplifier (e.g., op-amp, log-amp, or similar) and a 3-5 V battery. This apparatus is then attached to an LED. If signal is present, the LED lights. In the absence of signal, the LED is dark. See the attached circuit diagram and photo.
This could also be attached to a cell phone via the USB port, and the signal could be interpreted by a phone app, rather than the LED. We expect that this invention could also use an Arduino or Raspberry Pi instead of the amp. Other signaling devices are also possible.

Online meetings are increasingly becoming more common and replacing the traditional F2F meetings. The proposed access resolution methods enhance the online meeting experience by improving the efficiency of medium access among the participants.
Distributed scalable Floor Control Model for Audio & Video Conferencing 04/06/2015
This invention disclosure proposes an improved, distributed and scalable algorithm for determining the loudest N speakers in an A/V conference. We propose multiple scalable approaches for granting so-called floor access to a particular speaker (being the speaker in the A/V conference whose volume control is turned up while others are muted). Our approach is particularly well suited for (but not limited to) conferencing systems that are hosted in cloud computing environments. Furthermore, the distributed approach proposed here facilitates hosting of A/V conferences by different cloud providers more easily than a strict centralized model.
Novel space- and power-efficient ONU for MDUs 04/06/2015
Broadband customers increasingly start to consume video content (video, audio) either via an IP-based offering from their provider or via many of the available options for Over The Top (OTT) services. In addition, many subscribers no longer require voice service via their incumbent carrier, broadband provider or ISP, preferring to go with a mobile solution. MSOs and telcos are likely to respond by offering data-only services. In order to facilitate more effective ways to provide data-only services, we propose a new type of ONU. This so-called “Super-ONU” offers data-only services to subscribers via an integrated home networking technology.
Wireless signal strength and characteristic mapping using drones 04/06/2015
With wireless becoming pervasive (including Cable Wi-Fi everywhere initiative), drones could be used to measure wireless (including, but not limited to Wi-Fi or LTE) signal strength and characteristics in 3-dimensions, within or outside a building.
Using PacketCable for Non-Telephony QoS-Sensitive Applications and Services 04/06/2015
MSOs typically use PacketCable to deliver Dynamic Quality of Service for VoIP telephony, guaranteeing minimum parameters for IP traffic such as jitter, latency, and bandwidth. With adaptations, a Cable Modem can utilize PacketCable DQoS technology to provide prioritized packet flow for other services such as gaming, videoconference, and OTT video. Packaging this service as “GQoS,” or Guaranteed Quality of Service, can drive additional revenue by prioritizing packet flow for premium subscribers.
Cable plant repair via drones 04/06/2015
This invention describes ways in which cable plant equipment could be repaired in the field using drones. It involves drones attached with landing / gripping gear and a robotic arm to perform mechanical tasks. The extra power required by the drone during such an operation could be supplied via an external detachable probe, which can supply power during the operation. Three of these invention combine drones with robotics.
Character input method for one-handed remote controls 04/06/2015
We propose to add a touch-sensitive pad (called touchpad from here on) to a single-handed remote control. The touchpad and the associated circuitry have the capability to recognize letters that are being drawn on it. This input method is far faster and more convenient than selecting individual characters from a large grid of characters, using the arrow and other navigation keys.

Method To Determine Complex Frequency Response of Downstream Cable Plant 10/27/11
Two signal generators are locked up to a precise time standard, one at a hub site and the other at a test site that might be a home or a tap location. The generator at the hub site is offset from the generator by a frequency, such as 30 MHz that can propagate upstream. With common command and control, both generators step their way through a frequency band that needs to be tested for complex frequency response. A mixer in the hub site mixes the received test signal with the local offset signal. This generates a signal (e.g. 30 MHz) that is sent back upstream where it is demodulated in the hub site for amplitude and differential phase response. A number of methods are disclosed to provide a frequency reference for the two generators. In an alternative embodiment the demodulation can take place in the field, which saves returning the signal over the upstream band. The field demodulation can be done by synchronous conversion down to baseband I and Q, or by conversion to an intermediate frequency (IF)

Pre-Equalization Based Pro-active Network Maintenance Process Model for CMs Transmitting on Multiple Upstream Channels 6/24/09
This disclosure extends the process for analyzing the pre-equalization information to determine the gravity of the network problem and geographically isolating the source of the problem when the CM is transmitting on multiple upstream channels. Using multiple channels for upstream transmission is a feature in DOCSIS 3.0 to increase the transmission speeds. Though the pre- equalization parameters on multiple channels provide more comprehensive information on the spectral distortion, additional complexity is introduced in the analysis of these parameters. This disclosure and the attached paper explains the methodology used to address the frequency dependency of the micro-reflection and correlating this information across multiple channels.
A Method for Seamless Channel Change (DCC) in a Plant With Strong Linear Distortion 9/11/08
This invention proposes a mechanism to effect a fast and optimized change to a new channel using DCC (DOCSIS 2.0 Dynamic Channel Change) in a strong micro-reflection environment. In this environment, the CM will be forced to perform initialization technique 2 that requires the CMTS to recalculate the pre-equalization coefficients after receiving the ranging request on the new channel and provide it in the ranging response. By deriving the pre-equalization coefficients for the new channel from the values used by the current channel, this proposal will eliminate the step where CM sends ranging request and CMTS communicates the pre-equalization coefficient using an unsolicited ranging response. The seamless approach defined in this disclosure will be useful in supporting business services where stringent SLA requirements are placed. In addition, it will improve reliability and service assurance of voice services by decreasing the number of dropped calls.
A Method for a CM to Optimize Initial Ranging of Multiple Channels for DOCSIS 3.0 in a Plant With Strong Linear Distortion 9/11/08
Similar to storing the power level, this invention proposes storing the pre-equalization coefficients along with upstream channel ID in non-volatile memory at the CM This invention proposes a mechanism for DOCSIS 3.0 CMs to optimize the performance of initial ranging in a strong micro-reflection environment when multiple channels are supported by applying the pre-equalization values extrapolated from the first channel in the ranging request for the subsequent channels as long as there are no stored pre- equalization coefficients. In the case of re-initialization of the modem, if the upstream channel has not changed, using the stored pre-equalization should be given precedence over the values used for the first channel. A benefit of this proposed mechanism is to reduce the burden on the CMTS in massive outage situation as the modems are brought back on-line. An added benefit of this mechanism is in reducing the time for the cable modem to achieve high fidelity transmission in both scenarios: massive outage or normal CM initialization process. The same approach is also valid in the case when the frequency of a channel in a MD-US-SG is changed or a new channel is added to the MD- US-SG.
