  • Publication number: 20250144873
    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 beamlets of varying or identical intensity, and each beamlet 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.

  • Publication number: 20250106472
    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: 20240251123
    Abstract: Systems and methods are presented herein for generating an augmented reality (“AR”) display with user interface (“UI”) elements that respond to changes in pupil characteristics in response to detecting device streaming content. A media stream playing on a device that is within a threshold distance of the AR device is detected. The source of the media stream is identified. The AR device queries the source of the media stream for a consumption option. An AR overlay is generated and comprises selectable UI elements corresponding to the consumption options. In response to receiving an input at a UI element, the AR overlay is generated based on the consumption option.

  • Publication number: 20240123506
    Abstract: Disclosed herein are systems and methods of use thereof. For example, disclosed herein are systems and methods for printing using superluminescent light. For example, disclosed herein are methods of printing with superluminescent light, the methods comprising: generating a patterned light sheet from superluminescent light, with the proviso that the superluminescent light is not generated by a femtosecond laser; and projecting the patterned light sheet at an image plane onto or within a sample comprising a photosensitive material; thereby simultaneously illuminating a selected portion of the photosensitive material within a layer of the sample corresponding to a selected pattern, thereby causing a simultaneous photoreaction that prints structures in the selected pattern.

  • Patent number: 11880838
    Abstract: Systems and methods are provided for identifying an account via a hash key specific to the account and presented to a third party, in connection with a network interaction. One example method includes receiving, by a computing device, from the third party, the hash key in connection with the network interaction, determining a primary account number (PAN) for the account based on the hash key, and identifying an issuer of the account based on the determined PAN. The method also includes transmitting a verification request to the issuer, to verify details of the account, and receiving a code from the issuer indicative of the verification. The method further includes intercepting an authorization request for the network interaction based on the authorization request including the hash key and, in response to the authorization request further including said code, directing the authorization request to the issuer.

  • Publication number: 20220379235
    Abstract: Low Reynolds number forced convection heat transport within the fin channels enhanced by deliberate formation of unsteady, small-scale vortical motions using elastically fluttering thin-film reeds. The vortical motions substantially increase the local heat transfer coefficient at the channel walls and mixing between the wall thermal boundary layers and the cooler core flow. The flow mechanisms associated with production, advection and dissipation of these small-scale motions are investigated in a modular, high aspect ratio channel using micro-PIV, video imaging of the reed motion, and hot-wire anemometry. The global heat transfer enhancement in a modular heat sink prototype shows that the reed-induced small scale motions increase the turbulent kinetic energy of the flow even when the base flow undergoes transition to turbulence, leading to an increase in the local and global Nusselt number that is sustained at higher Re and a minor relative increase in losses.
