Heater Embedded Heat Sink/Cold Plate For Thermal Interface Material (Tim) Heating, N/A

Defensive Publications Series

A phase change material (PCM) is used as thermal interface material (TIM) to mount a heat sink or cold plate on an electronic chip. The TIM can improve thermal conductivity and heat dissipation between the semiconductor chip and heat sinks. In the manufacturing process, the PCM is heated right after heat sink/cold plate installation during which it undergoes melting or softening, effectively filling the air gaps between the chip and the surface of the heat sink or cold plate. The heating of the PCM can be performed using passive heating or active heating, which requires wasteful heating of the entire …

Managing Spatial Affinity For Edge Application Development And Deployment, Myungjin Lee, Brianna Marie Barrow, Ramana Kompella

Defensive Publications Series

Current approaches for associating edge devices with the correct application instance as edge devices are on the move often require changing end device configuration/policy, which can be inefficient and burdensome. In order to address such issues, techniques proposed herein provide a library of tools, including an affinity manager, to enable scalable edge application development, deployment and management. The affinity manager facilitates communication between service instances and edge devices by registering service instances and providing edge device with information on the service instances. When an edge device moves to a new area, the proposed techniques leverage a local area translation function …

Intelligent Provisioning Of Digital Experience Monitoring Agents Based On Observed Network Service Flows, Jay Kuhne, Peter Clayton-Luce, Steve Holl

Defensive Publications Series

Current network observability discovery and design of network monitoring tools for a network operator is often dependent upon the analysis of a network configuration and anecdotal input from the operator indicating their perceived service-level assurance needs. Specifically, the placement of monitoring agents within a network for such designs is fairly subjective and may not be reflective of the actual usage patterns and utilization of the network for traffic initiated by end-users or applications. This proposal leverages actual network behavior in order to generate recommendations for agent placement, as well as to optimize agent placement and, optionally, to auto-deploy an agent …

Passive User Satisfaction Monitoring For Performance Evaluation Of Natural Language Interface Systems, Sofia Karygianni, Yannick Weibel, Timothy Stirling

Defensive Publications Series

Proposed herein is a novel, passive approach for monitoring user satisfaction for interactions with a Natural Language Interface (NLI) system. Specifically, a novel architecture or system is proposed through which satisfaction metrics can be leveraged to actively monitor NLI performance. In some instances, automatic retraining processes may be activated, if necessary. Thus, the system may ensure a continuous enhancement of an NLI, which may lead to an elevated user experience without the need of external user or administrator intervention.

Optimizing Llm-Based Queries And Responses Using Secure, Portable, And Personalized Encoded User Profile, Cameron Lui, Aizhan Ibraimova, David C. White, Rajeshri Prashant Survase, Bachir Chihani, Tiffany K. Pham

Defensive Publications Series

Current large language model (LLM)-based platforms offer interactive user experiences with limited personalization. Although these LLM-based platforms can leverage publicly available and trained data to provide contextual responses to user queries, they cannot securely leverage private data about the user to personalize the experience. As a result, current systems lack the ability to provide context-sensitive and personalized content that meets specific user requirements or preferences. Moreover, robust privacy safeguards are needed to properly leverage and optimize a user’s private data for content delivery. To address these issues, proposed herein are techniques for providing an application programming interface (API) service that …

Stack Control Masking, Hp Inc

Defensive Publications Series

In some scanning printers one possible image quality issues is dark light zone banding, where regions whose intended tone is constant smoothly (rather than abruptly) oscillate in lightness, with a period equal to the media advance. The causes behind it can differ and depend on the type of ink and substrate. For some types of inks, drying can also play a crucial role. The printing process must be robust against dot-placement variations, including those due to variations in media advance, and ink-media interactions. The ink on media interaction in particular can also be correlated to the drying performance, to have …

LTE Cat-M1 is a Low-Power, Wide-Area Network (LP-WAN) designed specifically for purpose-built devices (like trackers) that transmit small to medium amounts of data over wide ranges.

While implementing the LTE Cat-M1 into the laptop, it would periodically report the position and device status to the cloud server even the laptop is in power save mode (S4/S5) without OS operation.

In this disclosure, we are going to further enhance the low power feature, minimize the total amount of data transfer (within a fixed period), and further enhance the trajectory accuracy of Cat-M1 module in the laptop.

Expediting Evpn Bgp Graceful Restart Using Route Type Info In End Of Rib Messages, Anonymous

Defensive Publications Series

This innovation solves issues in EVPN BGP Graceful Restart (GR) by adding EVPN Route type Information in a BGP update carrying an End of RIB (EOR) message in such a way that BGP speaker sends separate EOR for each EVPN Route Type, enables faster convergence. The Normal EOR message does not selectively work on EVPN Route Type. This adds delay in BGP GR convergence. Since some EVPN route types are part of different BGP RIB tables, it is more logical to have separate EORs for different Route Types.

Diffractive Waveguide Grating For Improved Image Sharpness In Augmented Reality Displays, Thomas Hoekman, Jun Yang

Defensive Publications Series

Diffractive, waveguide-based, augmented-reality displays couple light from a light engine into an optical waveguide while enabling environmental light to enter the eye. Phase discontinuities at diffraction-grating boundaries of the waveguide can cause a drop in image quality. This disclosure describes techniques to mitigate phase discontinuities between adjacent regions of a grating structure by adjusting the difference in residual layer thickness (RLT) of the waveguide between its blank regions and its input coupler. The RLT can be adjusted by controlling the spacing/size of inkjetted droplets in an inkjet nanoimprint lithography process; by secondary etching/ablation/polishing of the RLT; by introducing a depth …

Improved Image Quality In Near-Eye Displays Via Pre-Imprint Surface Modification, Thomas Hoekman, Joe Lowney, Kang Luo

Defensive Publications Series

Inkjet nanoimprint lithography, a technique for fabricating waveguide combiners used in near-eye displays (NEDs), can introduce predictable surface variations (ripples) in the diffractive waveguide combiner. The ripples diffract and scatter light, reducing image quality. This disclosure describes techniques to reduce surface undulations in near-eye displays using waveguide surface modification and/or stamp surface modification. The techniques reduce the surface energy of the droplets deposited on the waveguide by the inkjet, causing them to spread out more and producing a smoother final surface, in turn resulting in better image quality with lesser scattering and diffraction. Surface modification can be made using surface …

Enhancing Retrieval-Augmented Generation With Permissions Awareness, Kishore Jagannath

Defensive Publications Series

The baseline capabilities of LLMs are not always optimally suited to respond to queries within organizational contexts that involve internal, proprietary content with domain-specific language and jargon. While retrieval-augmented generation (RAG) can enable LLMs to deliver responses that take into account proprietary content of an organization as query context, there is no well-defined approach to deploy RAG while safeguarding content. This disclosure describes techniques that enhance RAG to enable any user affiliated with an organization to perform semantic queries limited to the context of the documents the user has the rights to access. Permissions-aware RAG is implemented by retrieving the …
