  • Patent number: 11218767
    Abstract: 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).

  • Publication number: 20210001540
    Abstract: The present disclosure relates to a method for performing an additive manufacturing operation to form a structure by processing a photopolymer resist material. A laser beam is directed at a tunable mask. At least one emergent beam is collected from a plurality of emergent beams emerging from the tunable mask. The at least one emergent beam is collimated to create a collimated beam. Each emergent beam from the tunable mask has a plurality of beam lets of varying or identical intensity, and each beam let emerges from a unique subsection or region of the tunable mask. The collimated beam is focused into a laser beam which is projected as an image plane onto or within the photopolymer resist material, such that the same optical path length is created between the tunable mask and the focused image plane for all optical frequencies of the focused laser beam.

  • Patent number: 10144172
    Abstract: 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.

  • Patent number: 9950462
    Abstract: 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.
