A Software Method To Solve Wavy Line Effect While Drawing Slash Line On Touch Screen, Hp Inc

Defensive Publications Series

When we draw slash line on touch screen slowly for example 1inch/second, we will not able to get a

straight line on the screen like drawing in the direction of vertical or horizontal. From experiment, it is a

common defect of touch controller in the market. We can both find the defect in products as well as the

other laptop. Though that, feedback from IHV is it is the limitation of their algorithm of their ASIC. Here

we introduce a method to improve the quality by a software module and algorithm.

Finding (Partial) Code Clones At Method Level In Android Programs Without Access To Source Code To Detect Copyright Infringements Or Security Issues, Armijn Hemel

Defensive Publications Series

Nearly all programs for Android devices are distributed without source code being made available. This means that it is a lot harder to do audits of these programs for for example copyright infringement detection or security issue detection. By examining individual methods inside an Android program and comparing these to a database of methods from known programs it is possible to make an educated guess of which programs or program fragments are used in the program, and possibly detect copyright infringements or trojaned versions of programs.

Device To Apply Heat To Burn Hairs And Dirt That Clog Wheels Of Suitcases/Walkers/Strollers/Rollators/Chairs, Armijn Hemel

Defensive Publications Series

Suitcases, strollers, walkers, rollators, chairs and other objects with wheels often suffer from hairs and other dirt getting wrapped around the axles of a wheel, reducing functionality of the wheel, which will run less smooth, or even be blocked. Many objects do not allow easy replacement of wheels or axles to fix the problem. One solution is to mechanically remove these hairs, using scissors, knives or other sharp tools. The drawback of this method is that it could damage the object. Another method is to apply heat to melt the hairs. People have suggested to briefly heat the wheels using …

Fingerprint-Matching Algorithm Using Polar Shapelets, Firas Sammoura, Jean-Marie Bussat

Defensive Publications Series

An image, such as a fingerprint, can be decomposed into a linear combination of polar shapelet-base functions. This publication describes a fingerprint-matching algorithm that uses polar shapelet-base functions. Using polar shapelet-base functions, a fingerprint image block can be separated into components with explicit rotational symmetries. Polar shapelet-base functions can represent the fingerprint image through compact parameterization or encoder representation due to their interpretation in terms of the rotational angle 𝜃, and due to their separability by a distance r. Therefore, the use of polar shapelets enables a convenient and robust method to perform fingerprint image manipulation, analysis, and matching. Polar …

Improving Efficiency Of Citizens Broadband Radio Service Dual Connectivity And Citizens Broadband Radio Service / Wireless Local Area Network Radio Level Integration And Interworking, Mukesh Taneja, Indermeet Gandhi

Defensive Publications Series

Techniques are described herein for using Citizens Broadband Radio Service Dual Connectivity (CBRS-DC) to improve per-user throughput and mobility robustness. With CBRS-DC, a CBRS User Equipment (UE) can exchange data via a Master CBRS Device (CBSD) and a Secondary CBSD simultaneously, but control plane packets for both these CBSDs are sent only via the Master CBSD. In CBRS networks, the Spectrum Access System (SAS) may change the channel bandwidth allocated to a CBSD. The SAS could even remove all the resources allocated to a Master CBSD, which can create problems with DC operation in CBRS networks, particularly for denser deployments. …

Protecting User Privacy By Monitoring Api Queries, Matthew Sharifi, Bernhard Seefeld

Defensive Publications Series

This publication describes a method for protecting user privacy from targeted application interface program (API) queries made to a prediction service on a computing device. More specifically, the method involves utilizing an API Query Manager to monitor API calls made by applications to the prediction service. If the API Query Manager determines a lack of positive feedback (e.g., screen content presented on a display of the computing device does not match the personalized prediction returned from an API call), then the API Query Manager can throttle further API calls made by the application to protect user privacy.
