Wireless-Connection Drop Prediction, Warning, And Protection, Jim Sun, Aaron Lee

Defensive Publications Series

This publication describes systems and techniques directed to wireless-connection drop prediction, warning, and protection. A wireless-communication device, such as a smartphone, includes a wireless-connection manager application. The wireless-communication device, having a wireless connection to an access point of a wireless network, performs operations under the direction of the wireless-connection manager application to predict, warn, and protect a user of instances where the wireless connection may drop. The operations include determining that a quality metric of a signal supporting the wireless connection to the access point does not meet a threshold, determining that another access point to the wireless network is …

Selective Data Access In Dual-Sim Dual-Standby Devices, Robert Greenwalt, Sooraj Sasindran, Balaji Sampath, Xiangyu Chen, Shivank Nayak

Defensive Publications Series

In dual-SIM dual-standby mobile devices, two protocol stacks share one radio transceiver. Thus, only one SIM can task the radio transceiver at a time, with voice calls having priority over data calls. On such devices, a default data SIM is identified and the other SIM is a voice SIM by default. When using the voice SIM to make a voice call, the radio transceiver is tasked by the voice SIM, and data services, being provided by the other SIM, are suspended. It is advantageous to continue data services in parallel to the voice call. This disclosure describes techniques that enable …

Fingerprint-Matching Algorithms, Firas Sammoura, Kuntal Sengupta, Jean-Marie Bussat

Defensive Publications Series

This publication describes a fingerprint-matching algorithm that uses a fusion of minutiae and pattern-correlation matching. Instead of extracting minutiae points, the algorithm extracts small patches from the fingerprint image and transforms them into rotationally-invariant vectors. The algorithm divides each image to be evaluated, herein called an “enrolled” image, into “M” number of patches with a sliding distance of one (1) pixel. The algorithm also extracts “N” number of random patches from a stored image, herein called a “verify” image, and calculates the similarity between the “verify” rotationally-invariant vectors and the “enrolled” rotationally-invariant vectors. At this stage, the algorithm merges vectors …

Audio-Recording Techniques Using Machine Learning (Ml), Snehitha Singaraju, Moonseok Kim

Defensive Publications Series

This publication describes audio-recording techniques, which allow a user equipment (UE) to determine a user’s intent and apply audio beamforming and wind-noise filtering based on the determined intent. This provides the user with an enhanced user experience (UX) by enabling the user to focus on the moment and use the UE to record or capture the acoustic signals that best-represent the auditory scene. Among other aspects, the invention uses machine learning (ML) to analyze the auditory scene and the environment of the user.

Transferring Application Software From One User Equipment (Ue) To Another, Victor Carbune, Daniel Keysers, Thomas Deselaers

Defensive Publications Series

An operating system (OS) of a user equipment (UE), such as a smartphone, supports various first-party and third-party application software. Many application software offer personalized user experience (UX) depending on user settings. A user may spend a considerable amount of time and effort downloading the application software and configuring their settings. The user, however, periodically replaces the smartphone, and often they download and configure the settings of various application software again on the new UE, same as they had done on the previous UE. This leads to a lengthy process of migrating from one UE to another. This publication describes …

Serverless Cybersecurity Training

Defensive Publications Series

Training students and professionals in cybersecurity practices is expensive due to the complex laboratory environments required to properly isolate the trainees. Traditional methods include downloading and executing a virtual machine locally or accessing cloud-based virtual machines. In this work, this cost is reduced by obtaining static files from server that cause a user’s browser to execute an HTML5 Service Worker and a Web Worker. The Service Worker intercepts browser requests to one or more domains and redirects them to the Web Worker. The Web Worker, which provides the vulnerable services the trainee interacts with, responds to the user.

Identifying And Correcting An Edge-Fattened Area Generated By Stereo-Matching Techniques, Onur Guleryuz, Ambrus Csaszar

Defensive Publications Series

This publication describes an image-boundary manager used in an image-capture device. The image-boundary manager uses a low-complexity algorithm to compute an edge-fattened area of a foreground object included in an image of a scene generated by the image-capture device. After computing the edge-fattened area of the foreground object, the image-capture manager assigns correct depth values to the edge-fattened area such that the image-capture device renders the foreground object, in a modified image of the scene, accurately and without the edge-fattened area.

An Optimized Producer And Consumer Design Pattern To Control Data Congestion, Hp Inc

Defensive Publications Series

Exponential growth in computer networks has resulted in a tremendous amount of traffic variability in time scales ranging

from a few milliseconds to several hours. This leads to network traffic congestion which, if persistent, could lead to

significant data losses. Congestion losses cannot be avoided by modest increases in buffer capacity, it requires far more

creative solutions. Missing data points can result in misleading inferences which can, in turn, lead to wrong engineering

and/or business decisions. It is therefore important to identify ways to avoid loss of data packets at the receiving end and

thereby ensuring data integrity. Currently available …

Efficient Queue Management In A Packet Buffer Between Processes, Ian Wells, Kyle Andrew Donald Mestery

Defensive Publications Series

Techniques are described herein for queueing between multiple threads and processes. These techniques provide for a low-lock queue to allow multiple transmitters and receivers to successfully use a single queue efficiently. In particular, the techniques presented herein provide tactics for passing packets in a shared memory area from one process with threads to another process with a potentially different number of threads, requiring different transmitter (Tx) and receiver (Rx) queue counts on the two sides of the connection and avoiding stalls in the multiple workers as they operate on shared data structures.

Customizing User Interfaces Based On Usage Preferences And Practices, Matthew Urquhart

Defensive Publications Series

User interfaces (UI) of applications are designed to provide elements connected to all of the various features regardless of their frequency of use. The inclusion of features rarely used by a user within the application UI can lead to a cluttered interface that wastes screen real estate and makes it difficult for the user to select the elements for frequently used operations, thus slowing the user down. Applications sometimes provide users the option to control the visibility and grouping of the menu options and/or toolbar buttons; however, these options require manual input from the user. This disclosure describes adaptive UI …

Load Balancing Of Phone Traffic Generated From Web Interactions, Jared M. Zimmerman, Travis Neilson

Defensive Publications Series

Click-to-call actions, e.g., provided in online advertisements, enable users to call businesses by clicking on a link. When a number of users simultaneously perform click-to-call actions, such simultaneous requests can outstrip the capacity of a business to respond to queries. The techniques of this disclosure detect click-to-call attempts in excess of the capacity of a business and distribute caller load amongst multiple businesses that offer similar goods or services.

Guide Pin Holes For Blind Mating Of Connectors, Kiavash Faraji, Gordon Chan

Defensive Publications Series

Portable electronics have a charging port to which a user can connect a power cable. In situations where a large number of devices are being charged, e.g., at airports, schools, etc., a clutch of cables forms near the charging station that causes visual clutter and inconvenience. Some devices have a female charging port that can be mated with a male charger without a cable, e.g., by visually aligning the male and female connectors before mating. However, when a user is visually impaired, or where there are several simultaneous devices being charged, the mating of connectors is a difficult task that …
