IPC: H04L12/56
Filed: 2004-04-06
Granted: 2012-06-12
Abstract: A versatile and efficient technique for classifying packets in an intermediate node. According to the technique, criteria and rules associated with the packet are applied to one or more classification stages (700, 800, 560) containing content-addressable memories (800a, 800b) (CAMs). Each stage examines specific criteria associated with the packet, e.g., a packet field, and generates a rule and additional criteria. The additional rule and criteria are provided to the next classification stage. This process continues until a final rule is provided to a final classification stage (560). At the final classification stage, the final rule is used to generate an identifier, e.g., queue identifier(ID), associated with the classified packet.

Title: Trapped vortex combustor
Inventor: KENDRICK DONALD
IPC: F23R3/58
Filed: 2004-02-04
Granted: 2011-06-14
Abstract: A trapped vortex combustor for gas turbine engines. An annular combustor housing is provided having a plurality of inlet centerbodies disposed along a helical axis. The inlet centerbodies include a leading edge structure, opposing sidewalls, a pressurizable cavity, and a rear wall. Inlet centerbodies cooperate with adjacent structure and an aft bluff body to define a trapped vortex cavity combustion chamber for mixing an inlet fluid and burning fuel to form hot combustion gases. Mixing is enhanced by utilizing struts adjacent to the rear wall to create eddies in the fluid flow, and by injecting fuel and/or air in opposition to swirl created by the bulk fluid flow. Hot combustion gases are utilized in a turbine for extraction of kinetic energy, or in heat exchange equipment for recovery of thermal energy. High combustion efficiencies and less than 10 ppm emissions of oxides of nitrogen and of carbon monoxide are achieved.
