Patent number: 11966391Abstract: Systems and methods are disclosed for executing a query that includes an indication to process data managed by an external data system. The system identifies the external data system that manages the data to be processed and generates a subquery for the external data system indicating that the results of the subquery are to be sent to one worker node of multiple worker nodes. The system instructs the one worker node to distribute the results received from the external data system to multiple worker nodes for processing.Type: GrantFiled: January 31, 2023Date of Patent: April 23, 2024Assignee: Splunk Inc.Inventors: Sourav Pal, Arindam Bhattacharjee

Publication number: 20240086471Abstract: Disclosed is a data fabric service system that can be implemented in a distributed computer network, such as a data intake and query system. The data index and query system can receive a search query and define a search scheme for applying the search query on distributed data storage systems including internal data storage and external data storage. The data index and query system may provide a portion of the search scheme to a search service of the data fabric service system, which can cause worker nodes of the data fabric service system to perform various functions—including applying the search query to the external data storage based on the portion of the search scheme in order to obtain search results.Type: ApplicationFiled: September 19, 2023Publication date: March 14, 2024Inventors: Sourav Pal, Christopher Pride, Arindam Bhattacharjee, Xiaowei Wang, James Alasdair Robert Hodge, Mustafa Ahamed

Patent number: 11921672Abstract: Systems and methods are described for executing a query of raw machine data that is stored at a remote data store that may store heterogeneous data. The system can determine the directories or file types that may store event data and may instruct one or more worker nodes to access files that may store events based on the determined directories of file types. Further, the system may exclude files at the remote data store that may not be identified as potentially storing events enabling a query that implicates a heterogeneous data store to be efficiently executed.Type: GrantFiled: October 18, 2019Date of Patent: March 5, 2024Assignee: Splunk Inc.Inventors: Sourav Pal, Arindam Bhattacharjee, Timothy Tully

Patent number: 10948926Abstract: Systems and methods of the present disclosure address the capacity constrained vehicle routing (CVRP) problem that may be applied to a warehouse scenario wherein multi-robot task allocation is required. Conventional methods can solve CVRP instances up to 100 nodes. In the present disclosure, a nearest-neighbor based Clustering And Routing (nCAR) approach is provided that makes the systems and methods of the present disclosure scalable wherein the number of nodes can be in the range of several hundreds to several thousands within an order wave.Type: GrantFiled: June 28, 2018Date of Patent: March 16, 2021Assignee: Tata Consultancy Services LimitedInventors: Chayan Sarkar, Himadri Sekhar Paul, Arindam Pal, Arijit Mukherjee

Patent number: 10909462Abstract: A multi-dimensional sensor data analysis system and method is provided. The multi-dimensional sensor data analysis system receives indoor and outdoor location, online and physical activity, online and physical proximity and additional a plurality of inputs (specific to a user), for example, surrounding of the subject, physiological parameters of the subject and recent social status of the subject, both online and offline. The multi-dimensional sensor data analysis system processes these inputs along with the knowledge of past behavior and traditional parameters of location, proximity and activity by performing a multi-dimensional sensor data analysis fusion technique, producing one or more outputs, for example, predicting or determining a human behaviour to a given stimuli.Type: GrantFiled: May 20, 2016Date of Patent: February 2, 2021Assignee: TATA CONSULTANCY SERVICES LIMITEDInventors: Avik Ghose, Arpan Pal, Arindam Pal, Tanushyam Chattopadhyay, Santa Maiti

Patent number: 10296996Abstract: Systems and methods for planning location-sensitive probabilistic behavior based evacuation paths, in a building, from source nodes to sink nodes in a network of routes including a plurality of vertices and edges are disclosed. For example, input parameters including layouts, number of evacuees at each source node, transit time, predetermined time period and maximum capacity associated with each edge and vertex are received. Further, weak evacuation schedules at a state of the evacuees are defined based on the layouts of the building, number of evacuees, transit time and predetermined time period. Furthermore, a strong evacuation schedule is defined based on the weak evacuation schedules and maximum capacity associated with each edge and vertex. Moreover, a mapping is defined from the strong evacuation schedule to the weak evacuation schedules to obtain a probabilistic behavior model. Also, an evacuation path is planned, in real-time, based on the probabilistic behavior model.Type: GrantFiled: July 19, 2016Date of Patent: May 21, 2019Assignee: Tata Consultancy Services LimitedInventors: Arindam Pal, Francesco Parisi, Venkatramanan Siva Subrahmanian, Subhra Mazumdar

Patent number: 9972176Abstract: Methods and systems for planning evacuation paths are provided to identify an optimum path for evacuation of every evacuee from a region of interest. Methods of the instant disclosure ensure that for each suggested evacuation path, the capacity of any edge on the path is not exceeded and the evacuation time is minimum. A path once identified is maintained. A randomized behavior model is employed to re-distribute evacuees in emergency situations. This provides optimum evacuation time that employs an improved technique with optimized run time and evacuation time after taking into consideration herd behavior.Type: GrantFiled: July 19, 2016Date of Patent: May 15, 2018Assignee: Tata Consultancy Services LimitedInventors: Arindam Pal, Gopinath Mishra, Subhra Mazumdar
