Patent number: 10621383Abstract: A computer-implemented method and system automatically detects stress singularity in a three-dimensional (3D) computer-aided design (CAD) model. A potential area of high stress is detected. A finite element mesh of the 3D CAD model is refined, at least in the potential area of high stress, after which, whether the high stress value converges is determined. A user is alerted that the potential area of high stress is an area having one or more elements of stress singularity. Suggestions are made regarding how to eliminate the stress singularity and the user is enabled to modify the design of the 3D CAD model to eliminate the stress singularity.Type: GrantFiled: June 16, 2017Date of Patent: April 14, 2020Assignee: Dassault Systemes SolidWorks CorporationInventors: Li-Ling Huang, Prasad Nimmagadda, Subbi Reddy Chirla, Nandish Datti

Patent number: 7911942Abstract: Methods and systems for use in connection with an asymmetrical digital subscriber line (ADSL) system being available to provide voice service and data service to the customer's premises. One service of the voice service or the data service is in use at the customer's premises, and the exemplary methods and systems detect a request for provision of the other service. In response to the detection, impact information may be provided on performance of the one service in light of concurrent use of the other service. A list of modes of operation of the other service is provided. The subscriber may consider the impact information and the list of modes and respond with a selected mode of operation of the other service. The selected mode is detected and the other service is operated pursuant to the selected mode to the customer's premises.Type: GrantFiled: December 11, 2006Date of Patent: March 22, 2011Assignee: AT&T Intellectual Property I, LPInventor: Prasad Nimmagadda

Patent number: 6748069Abstract: A method and system for routing Calling Name queries in a locally competitive environment includes the creation of a Calling Name query having both the calling party number and the called party number. The query is routed to a service control point of the local exchange carrier, where the called party number is extracted to determine the Calling Name service provider for the called party. The service control point accesses a series of databases to route the Calling Name query to the proper service provider/destination. The databases include a database storing a table of subscribers and their choice for Calling Name service, a database storing porting status of telephone numbers, and a database storing information about distribution of other local number portability databases.Type: GrantFiled: September 19, 1997Date of Patent: June 8, 2004Assignee: BellSouth Intellectual Property Corp.Inventors: Prasad Nimmagadda, Anita H.

Patent number: 6477546Abstract: Recording transactions using a chronological list superimposed on an indexed list. A transaction log of transaction entries is maintained as a chronological list superimposed on an indexed list. Preferably, each transaction entry includes a transaction descriptor field, a time stamp field, a chronological list pointer field and an indexed list pointer field. A first chronological list pointer points to the oldest transaction entry in the transaction log and a last chronological list pointer points to the latest transaction entry in the transaction log. The chronological list pointer field of a transaction entry points to the next oldest transaction entry. The indexed list includes a number of indexed list entry pointers. Each indexed list entry pointer corresponds to an index and points to a transaction entry with the same index. The indexed list pointer field of a transaction entry points to another transaction entry with the same index.Type: GrantFiled: August 6, 1999Date of Patent: November 5, 2002Assignee: BellSouth Intellectual Property CorporationInventors: Syama S. Velamuri, Julia Torbert, Prasad Nimmagadda

Patent number: 6286011Abstract: Recording transactions using a chronological list superimposed on an indexed list. A transaction log of transaction entries is maintained as a data structure logically organized as a chronological list superimposed on an indexed list. In one aspect of the invention, the transaction log is implemented in an element of a telecommunications network. In another aspect of the invention, the transaction log is implemented in a computer system. Preferably, each transaction entry includes a transaction identifier field, a time stamp field, a chronological list pointer field and an indexed list pointer field. A first chronological list pointer points to the oldest transaction entry in the transaction log and a last chronological list pointer points to the latest transaction entry in the transaction log. The chronological list pointer field of a transaction entry points to the next oldest transaction entry. The indexed list includes a number of indexed list entry pointers.Type: GrantFiled: April 30, 1997Date of Patent: September 4, 2001Assignee: BellSouth CorporationInventors: Syama S.

Patent number: 6130941Abstract: A method and system for controlling access to information stored in an information database includes an unbundled port service control point coupled to an unbundled port information database. A signal transfer point routes line information database, calling name information, and other queries from an originating network to the unbundled port service control point. The unbundled port information database stores an unbundled port identifier that includes a dialing number for an unbundled port and a service provider identifier. The unbundled port information database also stores an information service identifier that includes a location for the database storing the service provider's information and access rights to that information for various networks. The unbundled port service control point extracts the originating network identity from the query and determines access rights to the requested information based upon the access rights for the information as stored in the database.Type: GrantFiled: January 29, 1998Date of Patent: October 10, 2000Assignee: BellSouth Intellectual Property CorporationInventors: Prasad Nimmagadda, Anita H.
