Patent number: 8352344Abstract: A network device coalesces data received from an exchange, and provides a user with the opportunity to receive fewer, but up-to-date, data updates from an exchange when duplicate prices become available or a large volume of prices becomes available suddenly. Accordingly, the trader can be assured of receiving non-duplicated prices that are fed at a rate that is cohesive with that trader's connection speed. The present invention is designed to conserve on bandwidth thereby increasing the likelihood that bandwidth will be available to receive desirable market information.Type: GrantFiled: June 19, 2012Date of Patent: January 8, 2013Assignee: Trading Technologies International, Inc.Inventors: Jens-Uwe Schluetter, Stephen A.

Patent number: 7925679Abstract: Disclosed is a technique for result set management. One or more result sets are stored. Each result set was generated by executing a query. When at least one of a number of result sets that may be stored and a number of bucket tables that may hold result sets is modified, it is determined whether any of the one or more result sets are to be removed. When it is determined that one or more of the result sets are to be removed, those result sets are removed.Type: GrantFiled: September 5, 2008Date of Patent: April 12, 2011Assignee: International Business Machines CorporationInventors: Michael Stephen Schwartz, Naga A.

Method and system for resolving memory leaks and releasing obsolete resources from user session data
Patent number: 7472144Abstract: A software program (12) is configured to initiate, process, and terminate user sessions (22, 26). A resource deallocation module (50) is linked to the software program (12) to deallocate allocated external resources of each object of a user session responsive to an impending termination of said user session. An automatic memory management module (40) is invoked by the software program with respect to said user session subsequent to the deallocation performed by the resource deallocation module (50) and prior to the termination of said user session.Type: GrantFiled: July 28, 2003Date of Patent: December 30, 2008Assignee: International Business Machines CorporationInventors: Naga A.

Patent number: 7430741Abstract: The present invention is an application-aware method for allocating resources to applications based on a set of predefined policies comprising a Resource Allocation Program (RAP). The RAP is application-aware in that the RAP does not arbitrarily allocate resources to requesting applications. Instead, the RAP allocates resources to requesting applications based on predefined policies. The RAP allows a user to define the resource allocation for each policy in a Resource Allocation Table and associate the applications with the policies in a Policy Application Table. When an application requests resources, the RAP looks to the Policy Allocation Table to determine the policy associated with the application and looks to the Resource Allocation Table to determine the permissible amount of resources to allocate to the application associated with the policy. The RAP then allocates the resources to the requesting application.Type: GrantFiled: January 20, 2004Date of Patent: September 30, 2008Assignee: International Business Machines CorporationInventors: Naga A.

Publication number: 20070154037Abstract: A method and system is described to improve the reproduction of sound of an acoustic musical instrument. According to one embodiment, a first microphone is placed at a proximate location to the musical instrument to pick up the sound of the musical instrument. The sound as picked up by the first microphone is compared to a reference sound of the instrument (e.g., the sound of the instrument as perceived at a normal listening position). Based on this comparison, a tailor-made equalizer is designed to compensate for the differences between the sounds as picked up by the first microphone and the reference sounds of the musical instrument. Accordingly, using the tailor-made equalizer allows the reproduction of sound from the first microphone to have a quality similar to that of the reference sound of the musical instrument. In an implementation of the above system, a filter arrangement is provided having a low-pass and a high-pass filter that allows separate control of the frequency and/or gain for each filter.Type: ApplicationFiled: January 9, 2007Publication date: July 5, 2007Inventor: Stephen Schwartz

Patent number: 7231396Abstract: An abstraction layer (50) is provided for facilitating accessing a database (10) containing database records each including a plurality of fields stored in one or more tables (12, 14). The abstraction layer (50) includes a control table (52) containing control records corresponding to database fields. Each control record contains metadata associated with the corresponding database field. The abstraction layer (50) also includes at least one additional table (54, 56, 58, 60, 62, 64, 66, 70, 72, 74, 80) containing additional metadata. Each database field is selectively associated with one or more selected portions of the additional metadata through metadata contained in the control record corresponding to the database field. A user database application (30) accesses the database (10) using metadata obtained from the abstraction layer (50).Type: GrantFiled: July 24, 2003Date of Patent: June 12, 2007Assignee: International Business Machines CorporationInventors: Naga A.

Publication number: 20060106945Abstract: A system for enabling client software applications to interface with peripheral devices over a network. An application connection layer interfaces with a programming language of a client software application. A simple object access protocol (SOAP) client processor communicates with the application connection layer and a client software application using the application connection layer. The SOAP client processor includes an eXtensible mark-up language (XML) processor for converting data provided in XML format to a form usable by the client software application. A transport layer for interfaces with the SOAP processor and peripheral devices connected to the network.Type: ApplicationFiled: November 3, 2004Publication date: May 18, 2006Inventors: Robert Westervelt, Jayant Bhatt, Alan Curtis, Stephen Schwartz, Arturo Becerra

Publication number: 20060072768Abstract: A method and apparatus are described which reduce the presence of an unwanted signal. According to one embodiment, a first signal is provided from a desired location that includes an unwanted signal while a second signal is provided from an alternate location (e.g., one where the unwanted signal is less of a proportion of the total signal). The first and alternate signals are provided to respective signal processors. A level for a selected frequency band of the first and alternate signals is adjusted so that an increase in one results in a decrease in the other. Doing so allows the frequency band that includes the unwanted signal to be reduced in the desired first signal and filled in with a similar frequency band from the alternate signal.Type: ApplicationFiled: October 28, 2005Publication date: April 6, 2006Inventors: Stephen Schwartz, John Osmand, Damian Kulash
