Techniques To Improve Downlink / Uplink Decoupling For Citizens Broadcast Radio Service (Cbrs) And Other Shared Spectrum Wireless Systems, Mukesh Taneja

Defensive Publications Series

With downlink and uplink decoupling (DUDe), downlink (DL) and uplink (UL) need not be associated with the same base station in a wireless network. It helps to maximize DL and UL data rates, which and can lead to significant capacity, power, and outage gains.

There are limitations with using DL/UL decoupling for CBRS and other wireless systems where resources (such as channel bandwidth, maximum equivalent isotropically radiated power (maxEIRP), etc.) for some base stations are controlled by a Spectrum Access System (SAS) or an SAS-like entity. For example, SAS in current Citizen Broadband Radio Service (CBRS) systems (LTE-TDD Band 48, …

Uniform Tension Loading Toolkit (Utlt), Hp Inc

Defensive Publications Series

Uneven / wrong loading of material can be the source of many defect in print quality such as media skew. This

statement is particularly true in the textile printing business, where the customers are led to print on thin paper

or textile with challenging mechanical properties. In addition to that, the wider the print swath is, the more likely

printing defects due to loading material are to happen. For all these reasons, 3.2m wide printer such as the Stitch

S1000 have an increased risk of having print quality defect due to wrong loading of the media.

Intent-Based Service Automation For 5g Core Network Function Slicing, Viktor Leijon, John Mullooly, Scott Wainner, Fredrik Jansson

Defensive Publications Series

The techniques presented herein maintain network function (NF) resource adjacencies regardless of the shared or dedicated nature of the NF and independent of the segmentation of the NF's cluster resources across geographic management domains. To achieve this, the techniques use intent-based networking models in order to create NF resources that facilitate the network slice creation and resource allocation. More specifically, the techniques utilize a Yet Another Next Generation (YANG) model representation of a network slice to facilitate creation and state management of all NFs associated with a network slice instance. The YANG model enables inter-site and intercluster adjacencies where cloud-native …

Fused Filament Fabrication Printer With Integrated Bath, Jaime Van Kessel, Ruben Dulek

Defensive Publications Series

We designed an FFF printer with a heated print bed and a special bath arranged in the build volume. The bath can be filled with e.g. a mineral oil up to the nozzle height. As an object gets printed, the printed object gets submerged in the oil by lowering the print bed down into the oil, or in an alternative embodiment, by increasing the oil level. The mineral oil can transfer heat well and has a high surface energy. The oil will get heated up by the heated print bed. Because the oil has a high heat capacity (compared to …

Enabling Parallel Conversations In A Group Video Call, Gabriel Diniz De Faria

Defensive Publications Series

In a multi participant video conference (VC), it can be intimidating to start socializing or open a new subject. The sequential nature of microphone-passing obliges a participant uninterested in the present topic to wait it out before attempting to change topics. On the contrary, in a physical gathering, small groups of people form naturally to discuss topics of local and temporary interest, evolve, then disband. This disclosure describes techniques to simulate within VCs the natural social behavior of humans. A virtual conference hall is defined where avatars of VC-attendees are displayed. An attendee can whisper to nearby avatars. Two or …

Eliminating Redundant Media Uploads Using A Media Api, Thomas Deselaers, Victor Carbune

Defensive Publications Series

Users that share media such as pictures or videos via smartphones or other devices with cellular data connectivity often end up reuploading the same media via duplicate channels, e.g., multiple instant messaging apps, email, photo gallery, etc. This is costly and can cause excess consumption of the user’s data plan. This disclosure describes a media API, implemented in a device operating system, that reduces such redundant media uploads. When a user attempts an action that requires media upload via an application, the application invokes the API to determine whether the media was previously uploaded via another application. If a prior …

Granting Traceability Of Assemblies By Ensuring Visual Accessibility Of Assembly Parts Labels Through A Virtual Vision System Implemented At Build Preparation Stage, Hp Inc

Defensive Publications Series

The ability to produce already assembled parts is a remarkable advantage of additive manufacturing

technology over traditional manufacturing. We define an assembly as a collection of parts that are

physically linked and share a common functional goal. Traceability of produced assemblies/parts is a must

for some key manufacturing verticals such as automotive, aerospace and medical. Meaning that all parts

must have proper and reliable identification system, thus enabling production and quality management

systems. Traceability of assemblies using part labels is challenging due to several factors. For instance,

some assembly part labels may not be visually accessible, thus blocking automated/manual quality …

Translating Between Realtime Bi-Directional Conversations And Push-To-Talk Systems, Faisal Siyavudeen, Sanjay Sinha, Ram Mohan R

Defensive Publications Series

The techniques presented herein provide an artificial intelligence (AI)-based conversational agent to allow communications between (i.e., “translate for”) a push-to-talk (PTT) client and endpoints that support real-time, bi-directional conversation, including voice over Internet Protocol (VoIP) endpoints (also referred to as IP telephony endpoints) and endpoints running multimedia applications that allow bi-directional, real-time conversation. These techniques are applicable when PTT deployments allow direct calls between endpoints that support real-time, bi-directional conversation (e.g., VoIP endpoints) and PTT endpoints. During these calls, the techniques may allow a caller from the real-time, bi-directional conversation endpoint to have a real-time or nearly real-time conversational experience …

Algorithm To Dynamically Recalculate The Ink Linearization Tables In Printing Direction Based On The Position Of Images On The Media, Hp Inc

Defensive Publications Series

Some PageWide array printers use two different ink linearization tables in the printing direction (and a

transition table between them) to address the color density problem caused by the interaction between the

airflows and the vacuum. All these tables are generated assuming zero-margin between the printed image

and the leading edge of the media. Therefore, when printing with different margins or when images are

clipped, the default ink linearization tables and the transition table are not valid. To overcome this

limitation, we propose a method that dynamically recalculates the transition table so that the ink

linearization tables are applied correctly.

Saving And Recalling Interaction Sequences Of In-App Actions, Victor Carbune, Matthew Sharifi

Defensive Publications Series

When using apps, users can encounter difficulties in figuring out or remembering how to perform action sequences pertaining to specific tasks, especially tasks that are complicated or rarely performed. After successfully performing such tasks, it is cumbersome for the user to remember the details at a later time when they need to perform the task again. Currently, apps or devices do not provide users with the ability to capture and save these details for later recall and use. This disclosure describes techniques that, with user permission, save sequences of actions performed with an app on their device. The user can …
