Publication number: 20230147768Abstract: A system for behaviour mapping and categorization of objects and users in an 3D environment for creating and learning user behaviour map is provided. The system includes a robot 102, a network 104 and a central AI system 106. The robot 102 is embedded with an array of acoustic sensors 108 and visual sensors 110 for behaviour mapping and categorization the objects and users in the 3D environment and generates an auditory behaviour map and a visual behaviour map based on sensory inputs from the acoustic sensors 108 and visual sensors 110. The robot 102 transmits the acoustic source sensory input and the visual source sensory input to the central AI system 106 over the network 104 for generating a global behaviour map. The central AI system 106 tunes the global behaviour map to a specific user by tuning the detection and classification model to data obtained from a specific 3D environment that corresponds to the specific user.Type: ApplicationFiled: February 21, 2021Publication date: May 11, 2023Inventors: Sneh Vaswani, Prashant Iyengar, Chintan Raikar, Ravi Vaidyanathan

Patent number: 8768167Abstract: A single step routing and wavelength assignment method and system for automated provisioning of services on DWDM networks is presented. This novel single step solution automates design and assignment of services in DWDM networks. For an automated provisioning platform that can handle the routing and wavelength assignment in a single step, the solution avoids reconfiguration of existing services. It also takes into consideration practical aspects of DWDM transponder availability at termination sites and regeneration sites along the selected route. The methodology includes iterative computation of common channel sets to avoid multiple shortest path computations for each of the wavelengths.Type: GrantFiled: October 28, 2011Date of Patent: July 1, 2014Assignee: Telcordia Technologies, Inc.Inventors: Harshad Tanna, Sudha Ramesh, Ravi Vaidyanathan

Patent number: 7117030Abstract: A method and computer program product comprising an algorithm adapted to execute a method of identifying the spatial coordinates of a sustaining source of fibrillatory activity in a heart by computing a set of point-dependent dominant frequencies and a set of point-dependent regularity indices for a set of products of point-dependent unipolar discrete power spectra and point-dependent bipolar discrete power spectra, derived by spectral analyses of corresponding unipolar and bipolar cardiac depolarization signals simultaneously acquired from a set of points of the heart. A maximum dominant frequency is selected whose associated coordinates identify the point of the sustaining source of fibrillatory activity. The magnitude of the regularity index is interpreted to verify the identification of the spatial coordinates of the sustaining source of fibrillatory activity. When indicated, surgical intervention is directed to the spatial coordinates of the sustaining source of fibrillatory activity.Type: GrantFiled: December 2, 2004Date of Patent: October 3, 2006Assignee: The Research Foundation of State University of New YorkInventors: Omer Berenfeld, Jose Jalife, Ravi Vaidyanathan
