Intelligent And Dynamic Permission Model For User Permissions, Neil Dhillon, Tanmay Wadhwa, Young Lin

Defensive Publications Series

A permission model is described that provides a set of user modifiable default application permissions for user devices. A user interface enables the user to easily observe services and permissions being utilized by various apps and to update permission settings. Upon request, the user can grant permissions not granted by default at app initialization. With user consent, user actions to grant or deny access are logged to provide telemetry data regarding the user’s app usage patterns. App telemetry data from multiple user devices of consenting users are aggregated and combined with data obtained from app sources. The collected data are …

Dynamic Visual Indicators For Indicating Destinations Of Web Links, Spencer Johnson

Defensive Publications Series

Clicking on a web link sometimes takes the user to an unexpected destination or results in an unexpected operation, possibly exposing the user to undesirable content and resulting in a frustrating user experience (UX).

Non-Interfering Sequence For Massive Data Traffic In Low-Power Lossy Networks, Caijun Jiang, Dapeng Zhu, Yiyun Meng, Xiaopu Zhang

Defensive Publications Series

Techniques are described herein for generating a non-interfering sequence. This mechanism mainly comprises two steps. The first step involves computing and generating a schedule, and the second step involves receiving metering data from all nodes. After the second step ends, the head end system builds a residual node set containing all nodes that failed to report data in a given schedule, and then the first and second steps are repeated until the residual set is empty. The two steps are performed serially. The techniques described herein optimize these two steps. In particular, first a system mathematical mode is built from …

Improving Network Throughput Of Connected Grid Router Wireless Personal Area Network For Master And Slave Case, Yajun Xia, Yinfang Wang, Lele Zhang, Li Zhao

Defensive Publications Series

Techniques are described herein to cause a Master and Slave Wireless Personal Area Network (WPAN) to share the same 64-bit Extended Unique Identifier (EUI64) address. In response, the first hop dual-phy node transmits most of the upward data flow to the router via the Radio Frequency (RF) link, and the router transmits most downward data flow via the RF link. Because the RF link has much more bandwidth than the Power Line Communication (PLC) link, this mechanism takes full advantage of network resources and extends the network throughput.

Tileable Large-Scale Proximity Or Touch Sensor, Ian Muldoon, Patrick Gunderson

Defensive Publications Series

Large-scale touch or proximity sensors, e.g., sensors that span the wall of a home or office, have recently been described in research publications. Such wall-scale touch sensing technologies enhance a wall (or room) with sensing, interactivity, and computation, while retaining the look-and-feel of an ordinary wall. Wall-scale touch/proximity sensors that have been proposed thus far are not made of modular components. As such, each wall that is to be enhanced with touch/proximity sensing abilities is custom-treated based on the size of the intended display, using a labor-intensive process. This disclosure presents a design for a large-scale touch sensor that is …

Distributed And Collaborative Test Scheduling To Determine A Green Build, Keun Soo Yim

Defensive Publications Series

In the parlance of software testing and verification, a green build is a software build that passes tests on all reference devices. A green build is typically determined by a centralized test-scheduler. The centralized test-scheduler has a database of parameters, e.g., build-artifacts, build-branches, etc., corresponding to each device. The centralized scheduler uses the database to efficiently schedule tests. Centralized scheduling is computationally intensive, and maintenance of the database is a significant burden.

Per the techniques of this disclosure, devices in a pool collaboratively pick a new build to test. The first device to start within a given scheduling interval picks …
