Patent number: 9331947Abstract: Systems and methods can provide for packet-rate policing and admission control with optional stress throttling. In some implementations, a broadband device can monitor bandwidth usage and respond after exceeding a maximum packet-rate threshold based on a per-channel basis. In other implementations, a broadband device can monitor bandwidth usage and respond after exceeding a maximum packet-rate threshold based on a per-service-flow basis. In additional implementations, a broadband device processor can feedback data to the packet-rate policer to throttle the packet rate based on processor utilization. Policing data traffic based on packet-rate instead of bandwidth can increase flexibility to service providers as an increasing number of services are deployed to users.Type: GrantFiled: October 5, 2010Date of Patent: May 3, 2016Assignee: ARRIS Enterprises, Inc.Inventors: Francis Joseph O'Keeffe, Thomas Cloonan, Mark Lynch

Patent number: 8898136Abstract: A database statement categorization system can enable DBAs or other users to more easily find tunable database statements by categorizing the database statements. The database categorization system can analyze a DBMS to identify the types of database statements executed on the DBMS and can then categorize the statements automatically, outputting the categorization for presentation to a DBA (or other user). This categorization can advantageously separate less relevant statements that warrant less tuning or investigation from more relevant statements that may have a measurable impact on the performance of the database. By allowing users to focus on statements that are more likely to warrant attention, in certain embodiments the database categorization system streamlines the tuning process.Type: GrantFiled: August 26, 2013Date of Patent: November 25, 2014Assignee: Dell Software Inc.Inventors: Ariel Nissim Weil, Douglas Chrystall, Patrick Joseph O'Keeffe

Patent number: 6580961Abstract: A closed loop controller (6) has a measurement server (11) which captures measurement data from a measurement machine (3) via a link (22). It also receives production data indicating which placement machine parts were involved in depositing inspected items, via links (20, 21). The server (11) correlates this data and transmits it via a link (23) to a closed loop client (10), which generates process engineer displays of the correlated data and generates a control signal for the placement machine (2). These are fed back via a link (24) for automatic closed loop control.Type: GrantFiled: January 9, 2002Date of Patent: June 17, 2003Assignee: MV Research LimitedInventors: William Diggin, Kevin Keane, James Mahon, Joseph O'Keeffe, John Milroy
