Publication number: 20250144873Abstract: 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.Type: ApplicationFiled: January 9, 2025Publication date: May 8, 2025Applicant: Lawrence Livermore National Security, LLCInventors: Sourabh Kumar SAHA, Robert Matthew Panas, Shih-Chi Chen

Publication number: 20250106472Abstract: 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: ApplicationFiled: October 31, 2024Publication date: March 27, 2025Inventors: Harshith Kumar Gejjegondanahally Sreekanth, Ashwini Dharwa, Sourabh Kumar, Sukanya Agarwal

Publication number: 20220379235Abstract: 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.Type: ApplicationFiled: September 23, 2020Publication date: December 1, 2022Inventors: Ari Glezer, Thomas M.
