Publication number: 20110289922Abstract: An apparatus includes an electric generator having a stator and a rotor. A first turbine wheel is coupled to a first end of the rotor to rotate at the same speed as the rotor. A second turbine wheel is coupled to a second end of the rotor opposite the first end, and configured to rotate at the same speed as the rotor. The first and second turbine wheels may rotate in response to expansion of a working fluid flowing from an inlet side to an outlet side of the turbine wheels.Type: ApplicationFiled: May 28, 2010Publication date: December 1, 2011Applicant: Calnetix, Inc.Inventors: Scott R.

Publication number: 20110283702Abstract: A turbine wheel is rotatable in response to expansion of a working fluid flowing from near an inlet side towards an outlet side of the turbine wheel. The turbine wheel may receive the working fluid radially into the inlet side of the turbine wheel and output the working fluid axially from its outlet side. A generator has a stator and a rotor. The rotor may be coupled to the turbine wheel and may rotate at the same speed as the turbine wheel when the turbine wheel rotates. In certain instances, the generator is adjacent the inlet side of the turbine wheel.Type: ApplicationFiled: May 19, 2010Publication date: November 24, 2011Applicant: Calnetix, Inc.Inventors: David J. Huber, Scott R. Myers

Patent number: 7991196Abstract: Methods and systems for image processing are provided. A method for processing images of a scene includes receiving image data of a reference and a current frame; generating N motion vectors that describe motion of the image data within the scene by computing a correlation function on the reference and current frames at each of N registration points; registering the current frame based on the N motion vectors to produce a registered current frame; and updating the image data of the scene based on the registered current frame. Optionally, registered frames may be oversampled. Techniques for generating the N motion vectors according to roll, zoom, shift and optical flow calculations, updating image data of the scene according to switched and intermediate integration approaches, re-introducing smoothed motion into image data of the scene, re-initializing the process, and processing images of a scene and moving target within the scene are provided.Type: GrantFiled: June 17, 2010Date of Patent: August 2, 2011Assignee: Lockheed Martin CorporationInventors: Gene D. Tener, Barry Mattox, Jennifer K. Park, John Cowan, William R. Herzog, Hai-Wen Chen, James P. Kane, III, David J. Huber, Timothy Alderson

Patent number: 7898101Abstract: A gas turbine engine used to produce electric power is supplied with a fuel from a alcohol fuel producing process. A high pressure syngas left over from the alcohol fuel producing process is passed through a small turbine to drive an electric generator and produce electric power. The low pressure syngas from the turbine is then passed into a combustor of the gas turbine engine to power the gas turbine, which drive a larger electric generator to produce more electric power. The high pressure syngas can be passed through a heat exchanger to preheat the syngas prior to be burned within the combustor. By using the small turbine to reduce the pressure of the high pressure syngas, energy from the high pressure syngas can be extracted instead of wasted.Type: GrantFiled: November 29, 2007Date of Patent: March 1, 2011Assignee: Florida Turbine Technologies, Inc.Inventor: David J.

Patent number: 7740441Abstract: A small twin spool gas turbine engine with a bearing support arrangement in which the bearings are dampened by O-rings secured between the bearing races and the support structure, the bearings are arranged in series so that a cooling air can be passed through the bearings to prevent overheating, and the bearings are dry lubricated. The aft end of the engine includes high speed and low speed ball bearings supported with preload springs to add additional damping capability. The end bearing support assemblies form a cooling air path for the cooling fluid to flow through a passage within one of the guide vanes, through the bearings and a hole in the low pressure turbine rotor disk and out the exhaust of the engine. A snorkel tube extends into the bypass air channel drawing air for the bearings, and has a slanted opening preventing dirt particulates from entering the bearing cooling passage.Type: GrantFiled: August 1, 2008Date of Patent: June 22, 2010Assignee: Floride Turbine Technologies, Inc.Inventors: David J Huber, Cheryl A Schopf, Jack W Wilson, Jr.
