Embedded Backup Path Information For Stateless Srv6 Micro Segment Identifier Node Protection, Nagendra Kumar Nainar, Kamran Raza, Carlos M. Pignataro, Rajiv Asati

Defensive Publications Series

Techniques presented herein provide for the ability to improve Topology Independent Loop-Free Alternate Fast Re-route (TI-LFA) with node protection by embedding backup path information (on a per segment basis) in a stack itself. In particular, techniques herein introduce a Node protected Prefix/Adjacency Segment Identifier (NP-SID) with a new (yet simple) forwarding semantic that can be used to embed backup path information directly in a segment stack. The NP-SID is always followed by the backup node information in the segment stack and the forwarding semantic to the NP-SID will involve a lookup on the backup information only if a protected node …

Bgp-Mvpn Source Discovery For Multiple Rendezvous Points, Aswin Kuppusami, Vengada Prasad Govindan, Mani Panchanathan

Defensive Publications Series

In multi-site Border Gateway Protocol (BGP) Multicast Virtual Private Network (MVPN) deployments, it is common to have site local Rendezvous Points (RPs) behind each of the Provider Edge (PE) nodes that participate in MVPN communications. Multiple RPs are necessary for de-centralized management and are used to make receivers join the RP most suited to them in multicast. However, it has always been a problem in such topologies that have multiple RPs for receivers to find sources. Presented herein are techniques that provide a mechanism for MVPN source-discovery that can greatly improve the efficiency of source discovery. In addition, techniques herein …

Reducing Stress In 3d Objects Made Using Fused Filament Fabrication, Tim Kuipers, Johan Versteegh

Defensive Publications Series

We propose a new 3D printing method to lessen the effects of tension in FFF printed objects. By simply changing the toolpaths of the outer wall traces we can print materials that otherwise would need a heated chamber and strict temperature control to avoid deformations.

Sacrificial Process For Silicon Microchannel Wafer Enablement, N/A

Defensive Publications Series

Techniques are described for the enhancement of structural integrity of wafers that include microchannels. Silicon wafer microchannels are filled with sacrificial materials that can easily flow and fill the microchannel gaps, maintain their structural integrity during wafer processing, e.g. withstand wafer dicing, survive reflow temperatures, and possess deformation properties sufficient to absorb the stress and strain induced during wafer processing. In one option, a carrier wafer is attached to the bottom surface of the wafer to cap the channels. The microchannels are filled with filler materials, e.g. using a vacuum inducing or compressive process. In another option, the sacrificial molding …

Autonomous Monitoring Of Blood Alcohol Content, Yun Sun Lee, Luke Brantingham, Aaditya Kandibanda, Kavinaath Murugan

Defensive Publications Series

A system may autonomously monitor the blood alcohol content (BAC) and/or degree of intoxication of a user by using a machine learning module. The machine learning module may include a machine learning classification model trained on data relating to the user. The system may collect data relating to the user about a first set of characteristics, such as heart rate, body temperature, physical coordination, physical appearance, and speech quality.

Health And Safety Reminders Via Augmented Reality Glasses, Ruofei Du, Shengzhi Wu

Defensive Publications Series

With the proliferation of personal electronic devices, the time individuals spend using their devices is an increasing concern. In particular, users may unconsciously spend too much time looking at a screen; their eyes may be too close to a screen, leading to eye strain; their posture may be suboptimal, leading to back or neck strain; etc. This disclosure describes techniques to leverage depth information detected with user permission via one or more sensors to determine when such situations occur and to provide suitable reminders to users, e.g., via augmented reality (AR) glasses.

Remote Creation And Editing Of Augmented Reality Content Using Cloud Anchors, Yen-Lin Chen, Shengzhi Wu, Peter Tan

Defensive Publications Series

Adding augmented reality content, such as virtual objects, at a physical location currently requires the creator to be present at the location to capture a video of the scene and to add AR content. This disclosure describes the use of cloud anchors that enable a user to record a video at a location along with AR metadata such that AR content can be added to the location (or modified) at a later time when the user is at a different location. The cloud anchor can also be used for real time or offline with other users who are not at …

Dynamic Acoustic Transparency Control System, Guohua Sun, Leng Ooi, Jae Lee

Defensive Publications Series

A dynamic acoustic transparency control mechanism for audio devices such as headphones or earbuds is described. The acoustic transparency level for the device is adjusted based on ambient sound detected using an external microphone. In some configurations, an automatic gain control (AGC) block is utilized in the signal path to automatically boost ambient sound to a designed level. In some configurations, a sound pressure level (SPL) is determined based on sound received at the external microphone and a lookup table is utilized to determine a gain based on the received SPL. In some configurations, the applied gain is determined based …

Identifying Speakers And Limiting Displayed Transcription To Select Speakers, N/A

Defensive Publications Series

Machine-generated speech transcriptions are helpful for people that are hard of hearing or individuals who don’t understand the spoken language to understand conversations that take place near them. Augmented reality glasses can display speech transcriptions to help users understand such conversations. However, the display of transcriptions can be distracting when the user wearing the AR glasses is herself speaking. This disclosure describes techniques to automatically identify speakers in a conversation and only display live transcriptions of speech from conversation participants other than the person to whom the transcription is being provided. Speakers may be identified using user-permitted factors, e.g., by …

An Accelerated Peer-To-Peer (P2p) Communication Method Facilitated By Reusing Existing P2p Paths For Low-Power And Lossy Networks, Huimin She, Harbor Dong, Wenjia Wu, Nan Yi

Defensive Publications Series

The Wireless Smart Utility Networks (Wi-SUN) alliance promotes interoperable wireless standards-based solutions for Internet of Things (IoT) deployments, such as distributed automation (DA). For some applications, such as smart utility or smart city applications, it is desirable to provide optimized peer-to-peer (P2P) routing. However, for P2P traffic within a Destination Oriented Directed Acyclic Graph (DODAG), packets either have to be routed through a root in a non-storing mode or through a common ancestor in a storing mode. Techniques herein provide for locally reusing and distributing projected directed advertisement object (P-DAO) tracks. For example, when a node receives a P-DAO track …

Predicting Content Views Using Finite Integrals, Brian Mulford, Michael De Ridder, Colby Ranger, T. J. Gaffney, Jay Mithani

Defensive Publications Series

Video hosting and sharing services enable creators and advertisers to create campaigns that engage viewers. To price the advertisements, and to give advertisers on the campaign an idea of the popularity of the content, the viewership is predicted. Both under- and over-prediction of views are associated with penalties, respectively of wasted inventory and capacity crunches. View estimations based on channel average suffer from sample bias and invisible trends. This disclosure describes techniques of in-flight view prediction, e.g., predictions of views done after the launch of a campaign for the remaining days of a campaign. The predictions of the total views …

Gesture Disambiguation In Operating Systems, Jaeheon Yi

Defensive Publications Series

A visual operating system features multiple simultaneous clients displayed over a system user interface (UI). Examples of simultaneous clients are the accessibility client, the system UI, browsers, map-applications, etc. A touch gesture made by the user can be intended to be directed towards any one of the clients. However, in an architecture where no single component or client has global knowledge or ownership of all gestures, the client towards which the gesture should be directed is sometimes unclear. This disclosure describes techniques to disambiguate user gestures which can be incorporated in an operating system. The techniques enable simultaneously-running clients to …
