Patent number: 11218767Abstract: Systems and methods for authorizing operations associated with blocked media assets using two-factor authentication. In some aspects, a media guidance application (e.g., executed by a set-top box or other user equipment used to store and display media assets) prompts a user for a password (e.g., a personal information number) in order to unlock the content for viewing. In response to receiving a second request from the user to perform an operation related to the media asset (e.g., delete), the media guidance application prompts the user for an additional factor confirming his or her identity, consistent with two-factor authentication protocol. If the user's identity is authenticated as a user that has authority to perform the operation related to the media asset (e.g., delete the stored media asset), the media guidance application performs the operation related to the media asset (e.g., deletes the media asset).Type: GrantFiled: October 8, 2020Date of Patent: January 4, 2022Assignee: Rovi Guides, Inc.Inventors: Harshith Kumar Gejegondanahally Sreekanth, Ashwini Dharwa, Sourabh Kumar, Sukanya Agarwal

Patent number: 10144172Abstract: The range of stretch-tunability of sinusoidal wrinkled surfaces that are obtained by compression of supported thin films is limited by the emergence of a period-doubled mode at high compressive strains. This disclosure presents a method to suppress the emergence of the period-doubled mode at high strains. This is achieved by compressing pre-patterned supported thin films, wherein the pre-patterns are substantially similar to the natural pattern of the supported thin film system. As compared to flat thin film systems, pre-patterned thin film systems exhibit period doubling behavior at a higher compressive strain. The onset strain for emergence of period-doubling is tuned by altering the amplitude of the pre-patterns.Type: GrantFiled: February 2, 2016Date of Patent: December 4, 2018Inventor: Sourabh Kumar Saha

Patent number: 9950462Abstract: Wrinkling of supported thin films is a strain-driven phenomenon that enables scalable and low-cost fabrication of periodic micro and nano scale structures. The morphology of wrinkles depends on both the magnitude and the nature of compressive strains that are applied to the thin film. This disclosure presents the methods to fabricate asymmetric 2-D wrinkled structures using biaxial compressive strains. The method relies on the dependence of wrinkle morphology on both strains and strain paths to generate asymmetric 2D wrinkles. Asymmetry is achieved by deliberately traversing the system through a strain state that creates cracks along a preferential direction. Fabricated patterns include non-uniform zigzag wrinkles that demonstrate period doubling only along one direction.Type: GrantFiled: December 17, 2016Date of Patent: April 24, 2018Inventors: Sourabh Kumar Saha, Martin Luther Culpepper
