Patent number: 12268980Abstract: Reusable filters for personal protective equipment (PPE) may prevent shortages of PPE and save fabrication time, resources, and money. Disclosed is a method and system for fabrication of nanofiber filter media for PPE. The method includes positioning a substrate to receive nanofibers thereon, providing a voltage gradient in a region of the substrate, and electrospinning nanofibers onto the substrate. The methods and associated systems allow autoclaving of the filter medium at temperatures of up to 300 degrees for sanitizing the filter medium. Additionally, the methods and associated system allow for the inclusion of an anti-pathogen agent in the nanofiber filter media.Type: GrantFiled: September 30, 2020Date of Patent: April 8, 2025Assignee: UCHICAGO ARGONNE, LLCInventors: Yuepeng Zhang, Devon J. Powers, Krzysztof Pupek, John N. Hryn, Gregory K. Krumdick, Santanu Chaudhuri

Patent number: 11461795Abstract: A method and system for detection, classification and prediction of user behavior trends using correspondence analysis is disclosed. The methods and systems reduce the n-dimensional feature space to a lower dimensional space for easy processing, improved quality of emerging clusters and superior prediction accuracies. Further, the method applies the correspondence analysis so that each user is assigned with a new coordinate in the lower dimension, which maintains a similarity, difference and the relationship between the variables. Once the correspondence analysis is completed, clustering or grouping of the coordinates based on the similar trends of the users is performed. Further, unlabeled cluster members are assigned class membership proportional to the labeled samples in the cluster. Finally, the method predicts the future actions of the users based on the past trends that are observed from the labeled clusters.Type: GrantFiled: September 20, 2018Date of Patent: October 4, 2022Assignee: FLYTXT B.V.Inventors: Noopur Jain, Santanu Chaudhury, Jobin Wilson, Prateek Kapadia

Patent number: 10178396Abstract: A video compression framework based on parametric object and background compression is proposed. At the encoder, an object is detected and frames are segmented into regions corresponding to the foreground object and the background. The encoder generates object motion and appearance parameters. The motion or warping parameters may include at least two parameters for object translation; two parameters for object scaling in two primary axes and one object orientation parameter indicating a rotation of the object. Particle filtering may be employed to generate the object motion parameters. The proposed methodology is the formalization of the concept and usability for perceptual quality scalability layer for Region(s) of Interest. A coded video sequence format is proposed which aims at “network friendly” video representation supporting appearance and generalized motion of object(s).Type: GrantFiled: December 30, 2011Date of Patent: January 8, 2019Assignee: STMICROELECTRONICS INTERNATIONAL N.V.Inventors: Santanu Chaudhury, Subarna Tripathi, Sumantra Dutta Roy

Patent number: 9813731Abstract: A video compression framework based on parametric object and background compression is proposed. At the encoder, an embodiment detects objects and segments frames into regions corresponding to the foreground object and the background. The object and the background are individually encoded using separate parametric coding techniques. While the object is encoded using the projection of coefficients to the orthonormal basis of the learnt subspace (used for appearance based object tracking), the background is characterized using an auto-regressive (AR) process model. An advantage of the proposed schemes is that the decoder structure allows for simultaneous reconstruction of object and background, thus making it amenable to the new multi-thread/multi-processor architectures.Type: GrantFiled: August 6, 2014Date of Patent: November 7, 2017Assignee: STMICROELECTONICS INTERNATIONAL N.V.Inventors: Santanu Chaudhury, Mona Mathur, Aditya Khandelia, Subarna Tripathi, Brejesh Lall, Sumantra Dutta Roy, Saurabh Gorecha

Patent number: 9219623Abstract: A method, system and apparatus to self-determine equalization parameters for a channel. An initiator sends an equalization insensitive signal (EIS) to a responder on channel to be equalized and begins a count. A responder responds with an EIS. When the initiator receives the response EIS the count is terminated. The count, which constitutes a measure of delay in the channel, may be used to determine desirable equalization parameters for the channel.Type: GrantFiled: September 30, 2004Date of Patent: December 22, 2015Assignee: Intel CorporationInventors: James A. McCall, Klaus Ruff, David Shykind, Santanu Chaudhuri

Patent number: 8578086Abstract: Link initialization techniques to decouple the read training from the write training. Read training may be accomplished in a robust manner before write training is performed. These techniques may provide significantly improved link initialization times. A user-programmable register within a dynamic random access memory (DRAM) module may be utilized by the decoupled read training and write training processes. The decoupling may result in shorter and more robust training segments that may support faster training and/or increased link speeds.Type: GrantFiled: September 25, 2009Date of Patent: November 5, 2013Assignee: Intel CorporationInventors: Santanu Chaudhuri, Klaus Ruff
