Publication number: 20140342700Abstract: System and method for seamless switching between operator networks is disclosed. The present invention relates to communication networks and, more particularly, to switching between operators in communication networks. A network element termed as the service aggregator is provided that resides in the operator's network and acts as an intermediate between the mobile user and the operator. In addition, a switching module is provided on the mobile device of the user that interacts with the service aggregator to perform switching. Base station continuously broadcasts signaling information to the mobile device. Based on such signaling information received, the mobile device decides if it wishes to switch to another operator's network. The service aggregator establishes connection with the service gateway of the new network. Further, service aggregator sends handover signal and the mobile device switches seamlessly to the new operator's network.Type: ApplicationFiled: September 17, 2012Publication date: November 20, 2014Applicant: ALCATEL-LUCENTInventors: Vikram Srinivasan, Supratim Deb, Kanthi Nagaraj

Patent number: 8833653Abstract: A system detects a transaction outcome by obtaining video data associated with a transaction area and analyzing the video data to obtain at least one video transaction parameter concerning transactions associated with the transaction area. The transaction area can be a video count of items indicated in the video data as detected by an automated item detection algorithm applied to the video data. The system obtains at least one expected transaction parameter concerning an expected transaction that occurs in the transaction area, such as a scan count of items scanned at a point of sale terminal. The system automatically compares the video transaction parameter(s) to the expected transaction parameter(s) to identify a transaction outcome that may indicate fraudulent activity such as sweethearting in a retail environment.Type: GrantFiled: February 3, 2012Date of Patent: September 16, 2014Assignee: Stoplift, Inc.Inventors: Malay Kundu, Vikram Srinivasan, Joshua Migdal, Xiaowei Chen

Patent number: 8798896Abstract: A method and system for increasing accuracy in estimating average time taken to travel through a chosen road segment is provided. The method includes determination of time taken by one or more vehicles to travel through the road segments. Further, correlated road segments for which time taken to travel through the correlated road segments is correlated with the time taken to travel through the chosen road segment, are identified. A data repository stores a list of the one or more correlated road segments. Among the correlated road segments, one or more preferred road segments that increases the accuracy in determining the average time taken to travel through the chosen road segment, is determined by at least one processor. Further, the processor estimates the average time taken to travel through the chosen road segment using, data corresponding to time taken to travel through, the preferred road segments and the chosen road segment.Type: GrantFiled: October 27, 2009Date of Patent: August 5, 2014Assignee: Alcatel LucentInventors: Vikram Srinivasan, Avhishek Chatterjee, Samik Datta, Supratim Deb, Sharad Jaiswal

Publication number: 20140153503Abstract: Systems and methods for beaconing and management in bandwidth adaptive wireless networks are disclosed. The present invention relates to bandwidth allocation for access points and, more particularly, to bandwidth allocation for access points in wireless networks. The method employs mechanisms for beaconing and management to associate clients with Access Point (AP). The beaconing mechanism allows the client to discover part of the spectrum over which an AP operates efficiently. Periodic beacon messages are sent by AP to the client over the bandwidth of operation of the channel. The client then sends a client association request and gets associated with the AP. Further, critical information is conveyed to the AP in the beacon message. The AP further allocates the client to one of its radios of operation. The system is configured to handle disruptions and switching the AP to different parts of the spectrum during such disruptions.Type: ApplicationFiled: March 23, 2012Publication date: June 5, 2014Applicant: ALCATEL LUCENTInventors: Vikram Srinivasan, Supratim Deb, Kanthi C N, Piyush Gupta

Publication number: 20140112275Abstract: QoS aware multi radio access point for operation in TV whitespaces is disclosed. The present invention relates to operation of access points and, particularly, to operation of access points in TV whitespaces. The AP is configured to intelligently choose the radios, determine available whitespaces in the spectrum and allocate radios to the available whitespaces in the spectrum. The method determines clients that need to be serviced by the AP and assigns each client associated with AP to one of the radios. In addition, the method also takes care of QoS requirements for different services and hence every service is addressed to satisfy its QoS requirements. The method ensures that there is maximum utilization of available whitespace spectrum by accounting for the spectrum specific characteristics. The method considers bands for operation are spread across the spectrum and allocates the clients based on the availability of bands throughout the spectrum.Type: ApplicationFiled: April 8, 2011Publication date: April 24, 2014Applicant: ALCATEL LUCENTInventors: Supratim Deb, Piyush Gupta, Kanthi C N, Vikram Srinivasan

Patent number: 8570375Abstract: The present disclosure includes a system in which a video displayer, having access to video surveillance data and point-of-sale transaction data, provides random-access review of point-of-sale transactional video. Embodiments herein provide a new method of reviewing security video of a transaction taking place at a retail establishment's point-of-sale transaction area, or register. Embodiments herein enable random and instantaneous access to any number of transaction events that may be of interest to a loss prevention investigator. In one embodiment, a video displayer obtains video data comprising a point-of-sale transaction occurring at a point-of-sale transaction area, and transaction data from a point-of-sale terminal. The video displayer displays video of individual transaction events from a larger transaction, and visually modifies displayed video at a moment in the video when a transaction event occurs.Type: GrantFiled: December 4, 2008Date of Patent: October 29, 2013Assignee: Stoplift, Inc.Inventors: Vikram Srinivasan, Malay Kundu, Joshua Migdal, Matthew Farrow

Publication number: 20130265433Abstract: Methods and apparatus provide for a Cart Inspector to create a suspicion level for a transaction when a video image of the transaction portrays an item(s) left in a shopping cart. Specifically, the Cart Inspector obtains video data associated with a time(s) of interest. The video data originates from a video camera that monitors a transaction area. The Cart Inspector analyzes the video data with respect to target image(s) associated with a transaction in the transaction area during the time(s) of interest. The Cart Inspector creates an indication of a suspicion level for the transaction based on analysis of the target image(s). Creation of a high suspicion level for the transaction indicates that the transaction's corresponding video images most likely portray occurrences where the purchase price of an item transported through the transaction area was not included in the total amount paid by the customer.Type: ApplicationFiled: April 29, 2013Publication date: October 10, 2013Inventors: Malay Kundu, Brian Frank O'Donnell, Matthew K.

Patent number: 8448858Abstract: A system performs video identification of items involved with transactions, as captured in video data, and compares this item identification information with transaction data obtained from a transaction terminal such as a point-of-sale register to identify situations that are suspicious and may indicate fraudulent activity or operator error. In particular, the system as disclosed herein utilizes unique camera positions, and can use video data from more than one camera, to perform robust detections of fraudulent or suspicious activities associated with transactions in the transaction area. By obtaining video data originating from at least one video camera that monitors a transaction area, the system can automatically (i.e. no human involvement needed) analyze the video data to track items involved in a transaction in the transaction area.Type: GrantFiled: June 22, 2009Date of Patent: May 28, 2013Assignee: Stoplift, Inc.Inventors: Malay Kundu, Joshua Migdal, Vikram Srinivasan, Matthew Farrow
