Patent number: 12742651Abstract: The present disclosure relates to a system (300) for providing route guidance using augmented reality, the system includes a processor (502) to obtain a set of orientation parameters of a subject (304) based on one or more sensors accommodated in a computing device (302) associated with the subject and determine one or more motion parameters associated with the subject to reach the destination from a target location. The processor generates a set of arrows indicating at least one direction of the path from the target location of the subject to the destination, wherein when the set of orientation parameters deviates from the one or more motion parameters, the processor configured to calculate a degree of rotation to align the set of arrows indicating the at least one direction of the path along the desired direction to reach the destination to facilitate route guidance.Type: GrantFiled: December 7, 2023Date of Patent: September 22, 2026Assignee: CENTRE FOR DEVELOPMENT OF TELEMATICSInventors: Sudipta Roy, Avinash Kumar, Deepak Kumar Gupta, Lata Kiran Dey, Rajendra Kumar, Biren Karmakar, Shikha Srivastava

Publication number: 20170143207Abstract: Disclosed is an apparatus and method for detecting a brain lesion in a magnetic resonance (MR) image, and computer-readable recording medium for implementing the method. The apparatus includes an image area selector for receiving an MR image and creating an image of a brain portion (brain portion image) in which the brain portion is selectively presented; and an image processor for receiving the brain portion image and performing contrast adjustment on the brain portion image to obtain an image for diagnosis in which an area with a suspected lesion is emphasized.Type: ApplicationFiled: December 23, 2015Publication date: May 25, 2017Applicant: SUNGSHIN WOMEN'S UNIVERSITY INDUSTRY-ACADEMIC COOPERATION FOUNDATIONInventors: Sudipta Roy, Sanjay Nag, Samir Kumar Bandyopadhyay, Debnath Bhattacharyya, Tai-Hoon Kim

Patent number: 8840846Abstract: An apparatus for catalytic cracking of feedstock includes a first channel in which a feedstock is treated with an adsorbent to obtain a treated intermediate. The apparatus further comprises a separator-reactor vessel. The separator-reactor vessel includes an adsorbent separating region to remove the adsorbent from the treated intermediate. The separator-reactor vessel further includes a second channel connected to the adsorbent separating region. The treated intermediate is contacted with a catalyst in the second channel to produce a cracking yield. The second channel terminates in a catalyst separating region of the separator-reactor vessel. The catalyst is removed from the cracking yield in the catalyst separating region. The separator-reactor vessel further includes a physical partition disposed between the adsorbent separating region and the catalyst separating region to separate the two regions.Type: GrantFiled: March 30, 2011Date of Patent: September 23, 2014Assignee: Indian Oil Corporation Ltd.Inventors: Debasis Bhattacharyya, Gadari Saidulu, Arumugam Velayutham Karthikeyani, Pankaj Kasliwal, Bandaru Venkata Hari Prasad Gupta, Ram Mohan Thakur, Jagdev Kumar Dixit, Sudipta Roy, Ganga Shanker Mishra, Satyen Kumar Das, Santanam Rajagopal
