Patent number: 6625330Abstract: A method of doing meaningful modifications on an image is presented. These modifications can then be used in variety of applications related to image shape manipulation and similar shape retrieval. The method extracts macrofeatures and microfeature from a given shape. Deformations are done on the macrofeatures only. These deformations are either predefined, or are taken from a deformation library, or are calculated from the shape itself, The microfeatures are then added to the deformed macrofeatures to get a deformed shape. The shape deformations then allow user's perception of shape similarity to be learned, which is reflected in the values of parameters in a parameterized shape similarity metric. The user can use one of the deformed shapes as the initial query point, instead of the shape he or she started with.Type: GrantFiled: March 1, 2000Date of Patent: September 23, 2003Assignee: International Business Machines CorporationInventors: Pradeep Kumar Dubey, Sugata Ghosal, Ashutosh Kulshreshtha, Abhinanda Sarkar

Patent number: 6611834Abstract: A user at a client machine can customize components of a database search performed at a server. The user does this by sending executable code to the database server. Software code runs as middleware on the database server machine to communicate between the database server and the client and performs the functions of supplying the client with vital information required for generating code which will be used for customizing various processes of the database retrieval session. Typically, the server comprises a set of database servers and the middleware runs on each database server machine to communicate between the database servers and the client. The middleware provides a virtual machine on which the user-supplied code written in a virtual machine language is executed, giving a uniform interface across the set of database servers on which the same user-supplied code will be executed ensuring that the user-supplied code executes under database server specified access privileges.Type: GrantFiled: January 12, 2000Date of Patent: August 26, 2003Assignee: International Business Machines CorporationInventors: Gaurav Aggarwal, Deepavan Chakrabarti, Pradeep Kumar Dubey, Nitin Punamkumar Garq, Sugata Ghosal, Ashish Kumar Gupta, Ashutosh Kulshreshtha, Sreerama Kolluru Venkata Murthy

Patent number: 6560742Abstract: The present invention involves a method for generating a partial Cyclic Redundancy Checking (CRC) value of a first interval of data in a digital data stream. The method includes the step of loading a precomputed CRC value corresponding to a one bit followed by a predetermined number of zeros. The predetermined number of zeros correspond to the number of digits of a polynomial minus one. The first interval of data is partitioned into a plurality of bits. The precomputed CRC value corresponding to the one bit followed by the predetermined number of zeros is enabled, for each of the plurality of bits having a value of one. The enabled, precomputed CRC values are combined to generate the partial CRC value of the first interval of data. Advantageously, multiple copies of the process may be executed in parallel to achieve a large speed-up.Type: GrantFiled: December 9, 1999Date of Patent: May 6, 2003Assignee: International Business Machines CorporationInventors: Pradeep Kumar Dubey, Sanjay Mukund Joshi, Marc Adam Kaplan

Patent number: 6556281Abstract: A flexible chuck for supporting a substrate during lithographic processing is described. This flexible chuck includes an electrode layer, a piezoelectric layer disposed on the electrode layer, and a substrate support layer disposed above the piezoelectric layer. By providing electrical signals to the piezoelectric layer through the electrode layer, the support layer can be flexed, thereby changing surface topography on a substrate disposed on the flexible chuck. The contact layer can include projections, each of the projections corresponding to a respective electrode within the electrode layer. Furthermore, the substrate support layer can be formed of a conductive material and thus serve as the ground layer. Alternatively, separate substrate support and ground layers can be provided. The flexible chuck in accordance with the instant invention can be a vacuum chuck. Also described is a method of monitoring topographic changes in a flexible chuck in accordance with the instant invention.Type: GrantFiled: May 23, 2000Date of Patent: April 29, 2003Assignee: ASML US, Inc.Inventors: Pradeep Kumar Govil, Jorge Ivaldi

Publication number: 20030040897Abstract: A power management and control system having a dynamic data exchange (DDE) server simulator for simulating supervisory management and control of electrical distribution systems is presented. The DDE server simulator is an alternative DDE server which simulates device values rather than acquiring data from real devices. The DDE server simulator generates and calculates device data from user generated electrical property profiles and updates DDE compliant clients. The DDE server simulator accepts the actual topics and item names and power profiles are user configurable with an option to apply white noise to the data, which provides true-to-life values to the user. These simulated measured values are used to calculate derived parameters and pre-set arrays provide wave form data in the proper format. Device events and trips can be interjected by the user and properly interpreted by the simulator. The data is passed to the clients via DDE.Type: ApplicationFiled: March 8, 2001Publication date: February 27, 2003Inventors: Thomas Andrew Murphy, Kelley E.

Patent number: 6509952Abstract: Particular types of distortion within a lithographic system may be characterized by linewidth control parameters. Linewidth control parameters of any given line or feature within a printed pattern vary as a result of optical capabilities of the lithography apparatus used, particular characteristics of the reticle, focus setting, light dose fluctuations, etc. The instant invention uses focus offset coefficients to change the focus at points within a slot to compensate for the linewidth control parameter variations introduced by the factors contributing to such variations. Additionally, different focuses can be set dynamically along the scan for a particular slot point. A set, or sets, of focus offset coefficients is generated for a particular lithography apparatus, depending on the number of linewidth control parameters for which correction is desired.Type: GrantFiled: May 23, 2000Date of Patent: January 21, 2003Assignee: Silicon Valley Group, Inc.Inventors: Pradeep Kumar Govil, James Tsacoyeanes

Patent number: 6501757Abstract: An ATM switch having a plurality of input-ports and a plurality of output ports allowing a plurality of priority levels, which is highly modular allowing expansion of the number of cell buffers in a shared buffer pool, thus efficiently handling bursty traffic of one-to-one and one-to-many destination ports, using the bit slicing concept to reduce the operating speed of the switch, and decrease the cell buffer size requirement per slice along with reducing the number of shared queue memories per slice, aiding cost effective and efficient, very large scale integration (VLSI) implementation. It also allows configurability of input link speeds, taking care of the order of cell delivery to the output ports. The switch on receiving the input cell, searches for a free buffer in the shared pool, then routes the cell into this buffer and indexes the pointer into an output queue called the queue management module which uses a shared pool of queue memories.Type: GrantFiled: March 6, 2000Date of Patent: December 31, 2002Assignee: Centre For Development of TelematicsInventors: Muthusamy Kamaraj, Mariamma Joselin, Kalyanaraman Pattabhiraman, Satish Manohar Kulkarni, Jain Philip, Jayant Bhatnagar, Pradeep Kumar Bhatnagar, Kailash Narain Gupta, Adde Palli Gopinath Dixit
