Patent number: 10489577Abstract: One or more users (42) are identified based on typing pattern and/or behavior in a computerized system. A typing input is generated by one or more authorized users (42) by touching a touch sensitive input interface (12) at a touch coordinate that is linked to a given interface element displayed by the input interface (12). Collected touch coordinates are processed to generate a typing pattern specific of the authorized users (42), and the user-specific typing pattern is stored in a database (20). Touch coordinates generated by an un-identified user are processed to generate a typing pattern specific of the un-identified user (42), and the typing pattern of the un-identified user (42) is compared with the user-specific typing pattern stored in the database (20). The un-identified user is identified as (42) as one of the authorized users or as a non-authorized user.Type: GrantFiled: August 11, 2016Date of Patent: November 26, 2019Assignee: ONENIGMA LLCInventors: Faris Majed Toqan, Robert Maciej Pieta

Patent number: 9181812Abstract: A combustion device used in gas turbine engines to produce propulsion or rotate a shaft for power generation includes a can-annular combustor with a system of fuel and air inlet passages and nozzles that results in an optimal combustion environment of premixed fuel and air. The fuel-air inlets are placed at various longitudinal locations and circumferentially distributed, and direct the flow tangentially or nearly tangent to the can liner. The combustion device provides effective mixing of fuel and air, creates an environment for combustion that reduces pollutant emissions, reduces the need for costly pollution control devices, enhances ignition and flame stability, reduces piloting issues, and improves vibration reduction.Type: GrantFiled: May 3, 2010Date of Patent: November 10, 2015Inventors: Majed Toqan, Brent Allan Gregory, Jonathan David Regele, Ryan Sadao Yamane

Patent number: 9091446Abstract: A combustion device used in gas turbine engines that produces propulsion or rotates a shaft for power generation includes an annular combustor with a system of fuel and air inlet passages and nozzles that results in a flameless combustor, such that there is not an anchored flame as in typical gas turbine combustors. The fuel and air inlets are placed at various longitudinal locations and circumferentially spaced, and take on several different configurations where some nozzles inject only air and others inject a rich fuel-air mixture. The combustion device provides an optimal mixing of fuel and air as well as creates an environment for combustion that reduces pollutant emissions reducing the need for costly pollution control devices, and enhances ignition and flame stability, reduces piloting issues and improves vibration reduction.Type: GrantFiled: April 30, 2010Date of Patent: July 28, 2015Inventors: Majed Toqan, Brent Allan Gregory, Jonathan David Regele, Ryan Sadao Yamane

Patent number: 9052114Abstract: A combustion device used in gas turbine engines to produce propulsion or rotate a shaft for power generation includes an annular combustor with a system of fuel and air inlet passages and nozzles that results in a staged combustion of premixed fuel and air. The fuel and air inlets are placed at various longitudinal locations circumferentially, and can take on different configurations where all nozzles inject a fuel-air mixture or some may inject only air. The combustion device provides an optimal mixing of fuel and air, creates an environment for combustion that reduces pollutant emissions reducing the need for costly pollution control devices, enhances ignition and flame stability, reduces piloting issues, allows increased fuel flexibility, decreases the required size of the first stage nozzle guide vane (NGV), and improves vibration reduction.Type: GrantFiled: April 30, 2010Date of Patent: June 9, 2015Inventors: Majed Toqan, Brent Allan Gregory, Jonathan David Regele, Ryan Sadao Yamane

Patent number: 8904799Abstract: A combustion device used in gas turbine engines includes an annular combustor that contains the combustion process of air and fuel and then guides the hot gas products to a first stage turbine subsection of a gas turbine engine. The annular combustor has an inner/outer shell having corrugated surfaces that extend radially outward and inward across an entire hot gas stream inside the annular combustor. The corrugations twist about the engine centerline in a longitudinal direction of travel of the engine. The resulting flow path accelerates and turns the hot gas stream to conditions suitable for introduction into the first stage turbine blades, which eliminate the need for first stage turbine vanes. The annular combustor is configured with a system of fuel and air inlet passages and nozzles that results in a staged combustion of premixed fuel and air.Type: GrantFiled: May 25, 2010Date of Patent: December 9, 2014Inventors: Majed Toqan, Brent Allan Gregory, Ryan Sadao Yamane, Jonathan David Regele

Patent number: 7901203Abstract: A combustion chamber (1), in particular in a gas turbine, has at least two burners (A-H) that are connected to a fuel supply (3) via controllable fuel valves (2? and 2). Each burner (A to H) is assigned at least one optical measuring device (4) for detecting chemiluminescent radiation, and the combustion chamber (1) is assigned a pressure sensor (7) for detecting a combustion chamber pressure. The optical measuring device (4) and the pressure sensor (7) are connected to a computing and control device, which calculates a correlation value from the incoming measured values. A high correlation value signifies that the associated burner is prone to pulsation. The computing and control device (6) is designed in such a way that it determines the burner or a burner group with the highest correlation and controls the associated fuel valve(s) in such a way that more fuel is fed to the respective burner or the respective burner group, and the pulsation tendency thereof is thereby reduced.Type: GrantFiled: February 20, 2007Date of Patent: March 8, 2011Assignee: ALSTOM Technology Ltd.Inventors: Alexander Ni, Valter Bellucci, Peter Flohr, Bruno Schuermans, Majed Toqan, Ken-Yves Haffner
