Patent number: 8170838Abstract: The process of modeling a complex two-dimensional periodic structure is improved by selectively truncating the Fourier expansion used in the calculation of resulting scatter signature from the model. The Fourier expansion is selectively truncated by determining the contribution for each harmonic order in the Fourier transform of the permittivity function and retaining the harmonic orders with a contribution that is above a threshold. The Fourier space may be compressed so that only the selected harmonic orders are used, thereby reducing the required memory and calculation times. The compressed Fourier space may be used in a real-time analysis of a sample or to generate a library that is used in the analysis of a sample.Type: GrantFiled: April 27, 2009Date of Patent: May 1, 2012Assignee: Nanometrics IncorporatedInventors: Silvio J.

Patent number: 8160096Abstract: Methods and systems for reserving bandwidth in communications networks (e.g., time-division multiplexed (TDM) networks). A bandwidth request on a forward path of the communications network is temporarily held without any fixed slot timings. The bandwidth request is held for a time long enough for the request to travel the forward path end-to-end. Once the request reaches the destination of the forward path, the temporary bandwidth is confirmed by sending a bandwidth confirmation message back from destination to the source of the path. Each slave node along the path performs an allocation confirm with its associated master node, which responds by converting the temporary holds to full allocations by fixing slot timings.Type: GrantFiled: December 6, 2006Date of Patent: April 17, 2012Inventor: Michael Anburaj

Patent number: 8095507Abstract: A computer is programmed to parse a network that interconnects databases in a distributed database system, into a number of paths, wherein each path starts in a source database that is a source of changes and ends in a destination database that uses the changes to replicate the source database. The computer identifies databases that occur within each path in the network, and queries the identified databases to obtain statistics for each path. Statistics along each path are analyzed automatically, to identify a component in each path as a candidate for further investigation. The identified component may be marked as a bottleneck e.g. if there are no other paths connected to it. Alternatively the identified component may be a source of changes for another path that has a bottleneck or that has another candidate for further investigation. The identified bottleneck is displayed to the user with recommendations for improvement.Type: GrantFiled: August 8, 2008Date of Patent: January 10, 2012Assignee: Oracle International CorporationInventors: Jingwei Wu, Nimar S Arora, Lik Wong

Patent number: 8073826Abstract: A data stream management system (DSMS) is designed to support a new user-defined function, by creating and using at least two structures as follows. A first structure (“metadata entry”) is created in response to a command for creation of the new function, and maps a single instance of a class to the function's name. A second structure is created with creation of an operator on receipt of each new continuous query that uses the new function. The second structure (“operator specific data structure”) contains a path to the newly-created instance, which path is obtained by looking up the first structure. Additional second structures are created on receipt of additional continuous queries which use the new function, but all second structures contain the same path. All continuous queries use the same instance. Repeated use of a single instance to compile and execute multiple queries eliminates repeated instantiation of the same function.Type: GrantFiled: October 18, 2007Date of Patent: December 6, 2011Assignee: Oracle International CorporationInventors: Anand Srinivasan, Namit Jain, Shailendra Kumar Mishra
