Wireless Interface For Out-Of-Band Communication With Data Center Equipment, N/A

Defensive Publications Series

Organizations routinely invest in costly infrastructure such as switches and cabling to provide access to infrastructure devices like servers, network devices, storage, etc. Current management access techniques leverage local area network (LAN) on motherboard (LoM) to interconnect devices. However, LoM requires investment in additional cabling and infrastructure and can be quite costly. This disclosure describes techniques to reduce or eliminate infrastructure cabling between servers, network devices, storage, etc. Per the techniques, network interfaces to a physical cable and switch from a motherboard are supplanted or augmented with wireless connectivity options, e.g., WiFi, Bluetooth, etc.

Product Error-Correcting Codes That Span Nand-Flash Dies, N/A

Defensive Publications Series

NAND-flash memories include a matrix of pages. Each column of the matrix is located in one physical semiconductor die. Because errors are correlated such that they occur in groups within a die, error-correcting codes (ECC) are optimally constructed across dies (matrix rows), a principle known as cross-die design. A product ECC is a type of code that encodes rows to one parity and columns to another. Although the row-constituents of product codes are cross-die, the column-constituents are not so. This disclosure describes product ECCs where both constituent codes span semiconductor dies. The described cross-die product codes provide better performance for …

Shoulder Tap In Ambient Video Communications, Colvin Pitts, Aaron Donsbach

Defensive Publications Series

Many virtual meeting or virtual office apps provide users with a focus zone. Avatars of users in a focus zone are visible to other participants; however, users in the focus zone are shut out from ongoing conversations in their vicinity in the virtual office. A problem arises when a first participant desires to talk to a second participant that is in a focus zone or is otherwise engaged, e.g., in a separate conversation or simply away from their desk. This disclosure describes soft-alerting techniques to gently obtain the attention of individuals in a focus zone within an ambient video communications …

Crown-Based Authentication For Smartwatches, N/A

Defensive Publications Series

At present, a smartwatch can authenticate a user by using a nearby phone controlled by the owner of the smartwatch. However, requiring a nearby phone defeats portability. Also, a watch that retains authentication for purposes of payment constitutes a security risk. This disclosure describes techniques that leverage the haptic crown of a smartwatch to enter numbers in a rotary fashion on the smartwatch screen to authenticate the user for payment or contexts where authentication is necessary. Authentication can be retained on the device until the watch is removed.

Secure Wireless Localization Using Trusted Execution Environments, Avinash Kalyanaraman, Eric Voit

Defensive Publications Series

Through wireless localization, the position of a device (user) can be computed in a world coordinate system using wireless signals. Wireless localization systems for estimating device/user location typically involve fusing measurement data obtained from multiple access points (APs) by compute end-point, such as a cloud/edge-node. Such systems, however, are prone to attacks that can be launched against a compute end-point. To address such issues, techniques herein involve running wireless localization algorithms on a new paradigm of computing involving secure enclave technology through which localization algorithms can be protected from tampering. As a result, applications that may be vulnerable to location …

Improving Uniformity And Repeatability For Production Environments: Printer Calibration Focused On Manufacturing Applications, Hp Inc

Defensive Publications Series

The final energy adjustments on the MJF printing process are a key element to cover for the

known machine to machine variabilities. MJF 3D printers need to be energy calibrated to fine

tune part quality and, currently, it uses a job with seven levels of the same parts. In

each level, the printer changes the energy delivered by the fusing lamps and, after printing,

the user chooses the level with the best part quality. The energy corresponding to that level

is then applied to the printer as a standard to print the following production jobs.

Bug Management Using Machine Learning, Megha Jindal, Richa Gupta, Subham Mishra, Carlos Arguelles, Babu Prasad Elumalai

Defensive Publications Series

Automated tests of software can often independently log different bugs for the same underlying problem (root cause). Manually identifying duplicate bugs is a source of toil for engineers. A related problem of bug management is that of bug routing, e.g., determining the right team or person to route a bug report to for the purposes of debugging. This disclosure describes techniques for bug deduplication and bug routing based on machine learning (ML). Per the techniques, a binary machine classification model is trained to aggregate bugs with a common root cause. Bugs in a class of bugs with a common root …

Integrating Bug Deduplication In Software Development And Testing, Carlos Arguelles, Megha Jindal, Babu Prasad Elumalai, Subham Mishra, Richa Gupta

Defensive Publications Series

A bug deduplicator identifies independently discovered bugs that have the same underlying cause. Deduplication of bugs reduces toil for the software team by reducing the number of bugs that developers need to examine. However, if a bug deduplicator incorrectly classifies a bug as a duplicate, human developers might ignore the bug, allowing it to escape to production. A tradeoff exists between toil reduction and risk tolerance. This disclosure describes techniques that enable a software team to trade off the effort to remove bugs (e.g., auto-close bugs so that humans save toil and time) against the risk of errors in a …

Credit Card Selection Interface, Diane Spengel, Joao Menano

Defensive Publications Series

In financial services, consumers are offered a wide array of confusing options. Whether selecting a credit card, a debit/credit account, or other types of accounts, each typically has different benefits, restrictions, complex award programs and a plethora of other options. The best choice may depend on the consumer's own spending patterns and personal preferences or situation. It would be most desirable to have a user interface that clearly surfaces these different available options in an easy to navigate fashion.

Another difficulty for consumers arises in the activation of their financial instrument. It would be ideal to, at the close of …

Handover operations within a 3rd Generation Partnership Project (3GPP) fifth generation (5G) telecommunications environment may be inefficient and unnecessarily consume resources. To address such challenges, techniques are presented herein that optimize handovers through, for example, improving handover latency, avoiding unnecessary N4 interactions, and avoiding additional resource allocations in a User Plane Function (UPF). Additionally, in a home routed roaming case the presented techniques avoid extra resource allocations on a Home UPF (HUPF).

Method To Overcome Pdn Session Deletion During 4g To 5g Idle Mode Handover, Pavan Kumar Devulacheruvu Nageswararao, Anjaneyulu P.V.M.K.P, Jis Abraham

Defensive Publications Series

In some 4G/5G networks, 4G to 5G or 5G to 4G handovers are facilitated using Idle-mode handover techniques due to an unavailability of radio network element readiness to deploy Connected-mode handovers. However, Idle-mode handovers can lead to incorrect Packet Data Network (PDN) session deletion by a Session Management Function (SMF) during an Idle-mode 4G to 5G handover. Techniques herein address this issue by providing a solution in which an Access and Mobility Management Function (AMF) is to wait for the session management (SM) context creation procedure to complete before performing registration of a user equipment (UE) on a Unified Data …

Substrate Lateral Skew Measurement Using Two Line Sensors, Hp Inc

Defensive Publications Series

In most Large Format printers, loaded substrates to be printed may present a defect

called skew, in which the substrate is not aligned in the paper axis. This implies that

the substrate advance and printing directions are not perpendicular and thus the

resulting image orientation is slightly wrong. It might cause paper jams in the printer,

as well as different image quality issues derived from corrections wrongly applied.

An Optical Line Sensor is mounted on the carriage facing downwards and consists of

a light source and a densitometer. It can obtain a numeric value representing the

darkness or lightness reflected …
