A Method Of Reducing The Chances Of Service Interruption Due To Radio Link Failure, Shiangrung Ye

Defensive Publications Series

The operation of a user equipment is constrained during a prohibit time interval to reduce the likelihood of service interruptions due to a radio link failure. The constraints include preventing the user equipment from camping or connecting to the network via the cell during the prohibit time interval. The duration of the prohibit time interval is modified based on whether the radio link failure problem persisted (or reoccurred) following the prohibit time interval.

Just-In-Time Delivery Of Text-To-Speech Playback, Jared M. Zimmerman, Joe Ashear

Defensive Publications Series

In an interaction between a virtual assistant and a user, it is often the case that the responses of the virtual assistant arrive just after the passage of critical events in the user’s timeline. For example, navigational instructions to exit a freeway sometimes arrive just a bit too late to take the off-ramp. Some of this latency is attributable to the very nature of spoken audio playback: spoken audio playback being a linear medium, the length of time required for the spoken content to play can affect the accuracy of time-sensitive actions. This disclosure describes techniques that take into account …

Virtual Ambient Lighting For User-Interface Elements, Nick Bearman

Defensive Publications Series

This publication describes systems and techniques to adaptively apply virtual ambient lighting to user-interface (UI) elements on a portable electronic device. Portable electronic devices, such as smartphones, include a UI with passive elements and interactive elements. The UI generally presents elements, including interactive elements, as flat, two-dimensional objects. Because the UI does not intuitively differentiate interactive elements from passive elements, a user must rely on prior experience or trial-and-error to identify the interactive elements. This publication discloses a portable electronic device that captures and analyzes the lighting environment around the user of the device and displays onscreen elements as part …

Ad revenue associated with an ad impression is estimated and compared to the estimated direct cost. Based on the …

Memory Management Using Tab Discard And Reload Prediction, Jon Napper, Michael Giuffrida, Guoxing Zhao, Omri Amarilio, Grace Chung, Greg Granito

Defensive Publications Series

Browsers and other multi-tab applications discard tabs when there is insufficient memory. When a tab has been discarded, the user is forced to reload the tab to continue interaction. Selection of tabs to discard can be based on simple heuristics; however, such selection can lead to discarding tabs that the user is likely to use. Incorrectly discarded tabs are disruptive to users. This disclosure describes the use of machine learning techniques to generate more accurate predictions to select the tab to be discarded. Selectively discarding tabs in this manner can improve memory management while also providing a better user experience.

Lightweight Representation Of Multi-Origin Web Content, Ian Vollick, Calder Kitagawa, Robert Kroeger, Yaron Friedman, Sam Birch, Yusuf Ozuysal

Defensive Publications Series

Certain features such as browser tab previews, low-memory frame representations, etc., use low-fidelity snapshots of webpages. Low-fidelity snapshots can be created by rasterizing the webpage or by converting it to PDF format.

User Activity Prediction For Device Screen And Power Management, Jon Napper, Omri Amarilio, Dan Erat, Jia Meng

Defensive Publications Series

To save battery, consumer devices, e.g., laptops, smartphones, etc., enter low-power states based on user inactivity. Typically, a device enters a low-power state after a fixed time has elapsed since the last user activity, e.g., keyboard or touchscreen activity. However, a fixed timeout does not work evenly for all users; for example, it is found that a substantial fraction of users reactivate the device immediately after the device screen is dimmed or the device has entered sleep state. This disclosure describes machine learning techniques to predict the transition to a low-power state based on user activity patterns and the state …

Spatially And Temporally Directed Noise Cancellation Using Federated Learning, Shantanu Goel, Piyush T. Itankar

Defensive Publications Series

Machine learning models can be trained to cancel noise of diverse types or spectral characteristics, e.g. traffic noise, background chatter, etc. Such models are trained by feeding training data that includes labeled noise waveforms, which is an expensive and time-consuming procedure. Further, the effectiveness of such machine learning models is limited in canceling types of noise absent from training data. Trained models occupy significant amounts of memory which limits their use in consumer devices. This disclosure describes the use of federated learning techniques to train noise canceling models locally at diverse device locations and times. With user permission, the trained …

Illuminated Intra-Camera Privacy Mechanism, Anonymous

Defensive Publications Series

Conventional methods for providing a privacy shutter on camera devices have included external mechanical solutions, e.g., a physical lens clip or a physical lens cap that slides in front of a cover glass. These external solutions provide notification to a user that a privacy mode is active as the lens clip or lens cap can be seen by the user. However, these solutions are bulky and add mechanical complexity to the camera device design. Other methods include providing mechanical shutter inside the camera device. However, these fail to notify the user of the current privacy mode of the camera. This …
