Patent number: 8331270Abstract: In one embodiment a method is provided for requesting and receiving network statistics in-band of a data replication exchange. The method includes receiving, at a switch, a request packet, initiated from a data replication system, for in-band delivery of network statistics, modifying the request packet to include a command that can be processed by a data storage device that is periodically accessed in connection with the data replication system, sending the request packet including the command to the data storage device, receiving from the peripheral device, in response to the request packet including the command, a response packet that includes data responsive to the command, deleting from a data field of the response packet the data responsive to the command and adding to the data field network statistics data available to the switch, and sending the response packet including the network statistics data to one of another switch or a host device from which the request packet was sent.Type: GrantFiled: October 14, 2010Date of Patent: December 11, 2012Assignee: Cisco Technology, Inc.Inventors: Michael D. Blair, Praveen Jain, Cheyne Monroe Womble, Glenn C. Ferris, Mangesh Shingane

Patent number: 7653066Abstract: In network systems for transporting GFP-encapsulated FICON frames across a SONET/SDH transport network between FICON ports, the transport interfaces for the FICON ports operate to drop duplicate and out-of-order frames transported across the SONET/SDH network. The transmitting transport interface inserts a sequence number incremented with each FICON frame into said one or more transport frames, whereby the sequence number is used as an index for determining duplicate and out-of-order frames after transport over said SONET/SDH network. The receiving transport interface compares sequence numbers with each FICON frame to determine duplicate and out-of-order FICON frames, drops the duplicate and out-of-order FICON frames; and sends the balance of the compared FICON frames to the receiving FICON port.Type: GrantFiled: November 4, 2004Date of Patent: January 26, 2010Assignee: Cisco Technology Inc.Inventors: Ganesh Sundaram, Hitesh Amin, John Diab, Thomas Eric Ryle, Charles Allen Carriker, Jr., Marc Bennett, Michael D.

Patent number: 6705075Abstract: A method and device for producing a controlled combustion by placing a combustion chamber in communication with a feed chamber that contains a solid propellant/body, introducing at least a portion of the body into the combustion chamber, isolating the combustion chamber from the feed chamber, and igniting the solid propellant in the combustion chamber while the combustion chamber is isolated from the feed chamber.Type: GrantFiled: October 30, 2000Date of Patent: March 16, 2004Assignee: Alliant Techsystems Inc.Inventors: Thomas K. Highsmith, Michael D. Blair, Steven R. Wassom, William D. Starrett, Joel Dever

Patent number: 6220779Abstract: A joint is disclosed for connecting extruded segments to form a container, such as a pressure vessel for storing liquid propane. In cross section, joint includes a pair of symmetrical tabs, each tab configured at the end of adjacent arcuate outer wall segments. Tabs are configured for contiguous engagement to form a boss having a proximate neck portion and a distal body portion. Joint also includes a retaining member configured at the end of an internal web segment. Retaining member is configured to capture boss. A sealing weld is utilized to seal the adjacent tabs at exposed seam.Type: GrantFiled: March 5, 1999Date of Patent: April 24, 2001Assignee: Cordant Technologies Inc.Inventors: Mark J. Warner, Michael D Blair

Patent number: 6095367Abstract: A pressure vessel for holding a pressurized fluid such as compressed natural gas ("CNG") includes two end cells and zero or more interior cells. The cell geometry ensures that the cells meet one another at tangential circular surfaces, thereby reducing the tendency of adjacent cells to peel apart. A web secured about the cells includes two sheets that are tangent to the cells. Unused volumes between the cells and the web contain wedges of foam or rubber. A valve provides fluid communication between the interior of the pressure vessel and a pressurized fluid line. The filled weight of one pressure vessel does not exceed the filled weight of a conventional gasoline tank that occupies substantially the same space as the pressure vessel. The pressure vessel may be configured with exterior recesses for engaging conventional gasoline tank straps.Type: GrantFiled: September 23, 1996Date of Patent: August 1, 2000Assignee: Cordant Technologies Inc.Inventors: Michael D. Blair, Richard Kunz, Mark J. Warner, Kevin Davis, Edward Wolcott, Darrel Turner, John Bennett
