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.

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

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.

As the US frequency range of DOCSIS expands from 42 to 85 and beyond, there is a need to protect the input of the set top box from upstream bursts from in house or neighboring CMs, which would cause the RF input of the set-top box to saturate or for the AGC module to misbehave. A typical solution would be to use a switchable diplex filter, which is a solution that increases cost and backend support complexity.

Method to transform UML-based information models to various OSS components 7/31/14
When we create MIBs today (e.g., for DOCSIS), it is a very manual process. We first manually create a UML-based information model, then manually create a data model, then manually create MIBs, Yang Modules, TR-69/TR-181 models, etc. This is a slow, cumbersome, and error-prone process. Our invention would automate the creation of these models from the UML information model.

Offloading Logins 6/10/14
This invention allows for another entity to provide the credentials required for a login, without actually revealing them. Examples include a parent letting a child login use their credentials, and offloading authentication to a hardware box (like an STB), so that the user does not have to have credentials to login. Such a scheme can also be used for login by ‘applications’ which are not trustable with the user credentials.

Wireless Network Selection 6/10/14
One common problem encountered in community Wi-Fi networks is that as a broadband subscriber moves from out-of-range of private SSIDs to in-rage of private SSIDs, the subscriber device remains on a public SSID. One of the solutions provided so far is that the AP learns the MAC addresses of clients that have previously connected to its private SSID and once such clients are in its range, the AP blocks their association requests to the public SSID. In this disclosure, we propose an alternative solution.

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)

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.
