20140177051 | Holographic Display System - A holographic display system for producing three-dimensional virtual images that are similar those of a real object seen through a conventional glass window. A basic display element comprises a lens and an image element such as conventional display screen, film, slide, or photograph. For this embodiment, the distance between the image element and the lens is approximately equal to the focal length of the lens. This setup means that different viewing angles correspond to different physical locations on the image. The apparent magnification of the image element increases as the observer moves away from the lens, which simulates the reduction in viewing angle of a real window. Selecting a distance between the lens and display that is less than the focal length of the lens allows for more accurate representation nearby objects. Other embodiments use mirror or diverging lenses. Also a variety of configurations for producing, recording, and transmitting images are described that use single or multiple cameras. While a single display element can produce a useful image, multiple display elements can seamlessly create an image with binocular vision effects and realistic display of objects from multiple viewing angles. | 06-26-2014 |

20130098039 | EXHAUST DIFFUSER ADJUSTMENT SYSTEM FOR A GAS TURBINE ENGINE - A turbine exhaust diffuser adjustment system for a gas turbine engine capable of altering the flow of turbine exhaust gases is disclosed. The turbine exhaust diffuser adjustment system may be formed from one or more flow ramps positioned in a flowpath. The flow ramp may include a downstream, radially outward point that extends radially outward further from the ID flowpath boundary than an upstream, radially outward point that is positioned upstream from the downstream, radially outward point. The flow ramp may be adjustable such that an angular position of a radially outer surface of the flow ramp may be adjusted relative to the ID flowpath boundary, thereby enabling the flowpath to be changed during turbine operation to enhance the efficiency of the turbine engine throughout its range of operation. | 04-25-2013 |

20100076776 | Fundraising and Recruitment Methods - A computer-based system collects performance information, e.g., grades, submitted by students. The system automatically searches its database to see if the performance information satisfies any sponsorship pledges contained in the database. If so, the system executes the pledge and rewards the student for the good performance. The system can also be used to sponsor education programs, and to find suitable job candidates with the right performance records and credentials. | 03-25-2010 |

20080304954 | Highly Supercharged Gas Turbine Generating System - A highly supercharged gas-turbine generation system include a gas turbine power plant that is supercharged to a high inlet pressure, preferably over about 1.15 pressure ratio and preferably includes a transmission system with refrigerated transformers for increased output. The gas turbine power plant includes a precompressor that supercharges to a design pressure ratio of about 1.20 to 10, with a preferred pressure ratio of about 2. For high supercharging pressures, a pressure-reducer is located downstream of the gas turbine to maintain turbine outlet pressure that is close to the inlet pressure. The pressure-reducer is preferably an expander, but can alternatively be an orifice. A torque-limiting coupling on the shaft between the gas turbine and the generator prevents transient overload of the shaft. Capacity of the gas turbine plant is preferably controlled by varying supercharging pressure. The expander preferably has variable-pitch blades to allow efficient variation of turbine outlet pressure. For combined-cycle embodiments, a heat-recovery steam generator (HRSG) may be placed between the gas turbine and a downstream expander. For highest combined cycle output, a single-pressure steam system with high inlet temperature to the HRSG is preferred. The high temperature is preferably provided by supplemental firing between the gas turbine and the HRSG. An expander may be inserted between the supplemental firing and the HRSG to further improve cycle efficiency and to reduce pressure in the HRSG. For retrofit applications with limited supercharging, a refrigeration system for generator cooling may be added to increase generator output to match that available from the supercharged gas turbine. | 12-11-2008 |
