Thermal Downlink Throttle Ue Specific Approach, Blake Kragten, Shivank Nayak, Siddharth Ray

Defensive Publications Series

During operation, temperatures of a mobile communication device of an end user (user equipment or “UE”) can increase to high levels. In particular, UE temperatures can rise when receiving large amounts of data during downlink communication with a network. Generally, there is no ability to limit the amount of downlink throughput when the UE device is in single carrier mode. However, downlink throughput throttling can be used to thermally mitigate increasing UE temperatures. As the temperature of the UE increases, the network can be notified to decrease the amount of downlink throughput, thus reducing the power levels and the temperature …

Auto-Recovery Of Micro-Services In A Large Distributed Appliance Model, Kshitij Tanay, Raghu Rajendra Arur, Taj Uddin

Defensive Publications Series

In large distributed application-based systems, an ensemble of co-existing micro-services perform individual functions and communicate with other micro-services. As these interactions and individual behaviors can be complex, it may be necessary to monitor micro-services for any abnormalities. Manual monitoring of all such micro-services, or establishing individual rule-based alerts for micro-services can be time-consuming. In addition to maintaining functionality of micro-services, it is important to prevent micro-services from becoming a performance bottleneck for other micro-services. In such situations, an alert may not suffice. For example, if a micro-service serves as a data store for all other services, a bottleneck at that …

Screen Brightness Adjustment Using Machine Learning, Sandro Feuz, Thomas Deselaers

Defensive Publications Series

Mobile devices, e.g., smartphones, tablets, etc., often include a light sensor that senses ambient light. Data from this sensor is used to set the screen brightness. During ordinary usage of such devices, the light sensor sometimes gets covered, e.g., by the user's fingers, which leads to a quick decrease in screen brightness. This makes for a poor user experience. This disclosure describes machine learning techniques that determine whether a detected change in ambient light is due to a true decrease in ambient light conditions or due to an occlusion of the light sensor. Screen brightness adjustments can be made on …

Design Of Neural Networks Based On Cost Estimation, Yair Movshovitz-Attias, Andrew Poon, Ariel Gordon, Elad Edwin Tzvi Eban

Defensive Publications Series

Certain automatic designs of neural networks not only minimize prediction error but also shrink or prune the network to reduce inference latency. Targeting inference latency directly is difficult; hence, FLOP-count is often used as a proxy for inference latency. However, FLOP-count is only loosely correlated with inference latency.

This disclosure describes techniques for direct computation or measurement of targeted costs such as inference latency, energy consumption, throughput, model size, etc. By integrating such targeted costs into design procedures, high performance neural networks of low inference latency, model size, and energy consumption can be obtained. The techniques find application in domains …
