20110175517 | High-Definition Cathode Ray Tube and Electron Gun - A high-definition CRT is provided having an electron gun to produce high beam current without increasing spot size and to provide lower electrical power requirements at high beam-modulation frequencies. The electron gun includes beam-forming electrodes and a lens. Each beam-forming electrode has several aperture clusters operable to form several collimated beams of electrons. In addition, the lens is operable to focus the several collimated beams of electrons onto a display screen. | 07-21-2011 |
20120241590 | Method for Assembly of Spectroscopic Filter Arrays Using Biomolecules - Spectroscopic filter arrays and methods for making spectroscopic filter arrays are provided. The arrays are formed using a dispersion of filter particles having selected moieties attached to the surface of the particles and a microarray having complementary moieties formed in an array on a substrate, such that each filter particle is attached to a selected region of the microarray. The moiety on the substrate may be RNA or DNA or other molecule. The substrate may be a surface of a photodetector array, a transparent plate that may be placed in registration with the photodetector or a stamp used to transfer the filter array to a photodetector array. | 09-27-2012 |
20130153767 | Wavelength-Selective, Integrated resonance Detector for Electromagnetic Radiation - Embodiments of the invention are directed to integrated resonance detectors and arrays of integrated resonance detectors and to methods for making and using the integrated resonance detectors and arrays. Integrated resonance detectors comprise a substrate, a conducting mirror layer, an active layer, and a patterned conducting layer. Electromagnetic radiation is detected by transducing a specific resonance-induced field enhancement in the active layer to a detection current that is proportional to the incident irradiance. | 06-20-2013 |
20130218241 | Membrane-Supported, Thermoelectric Compositions - Thermoelectric devices and methods for making and using the devices and their intermediates are provided. Membrane-supported thermoelectric modules are fabricated by dispensing thermoelectric powder into select locations of a membrane to form electrically-isolated columns of thermoelectric material. The powder is then sintered or fused to form thermoelectric elements, which are then electrically connected and combined with thermal interface films to form the modules. The modules are the building blocks of electrical current generating, thermoelectric cooling and heat scavenging thermoelectric devices. | 08-22-2013 |

20080219853 | Multi-alloy turbine rotors and methods of manufacturing the rotors - A dual alloy turbine rotor is provided and includes an integrally formed blade ring and a disk. The blade ring is made of a first alloy and includes a ring portion and a plurality of airfoils extending therefrom, where the ring portion includes an inner surface, and each airfoil includes an internal cavity formed therein. The disk is made of a second alloy and may have a beveled outer peripheral surface. The disk is disposed within the ring portion such that the disk outer peripheral surface contacts at least a portion of the ring portion inner surface. Methods of manufacturing the turbine rotor are also provided. | 09-11-2008 |
20130280036 | AXIALLY-SPLIT RADIAL TURBINE - An axially-split radial turbine includes a forward rotor section and an aft rotor section being mechanically and abuttingly coupled to one another along an annular interface that resides within a plane generally orthogonal to a rotational axis of the axially-split radial turbine. The axially-split radial turbine can be provided as part of a gas turbine engine. | 10-24-2013 |
20140241906 | AUXILIARY POWER UNITS (APUs) AND METHODS AND SYSTEMS FOR ACTIVATION AND DEACTIVATION OF A LOAD COMPRESSOR THEREIN - Auxiliary power units and methods and systems for activation and deactivation of a load compressor therein are provided. Auxiliary power unit includes the load compressor having an impeller, APU engine, coupling member, pre-spinning means, and APU controller. APU engine is adapted to be mechanically engaged to load compressor to drive load compressor to provide pneumatic power and to be disengaged when the need for pneumatic power ceases. Coupling member couples load compressor and APU engine and is configured to be controllably moved between an engaged position in which the APU engine is mechanically engaged with the load compressor, and a disengaged position, in which the APU engine is disengaged from the load compressor. APU controller is operably coupled to load compressor, APU engine, coupling member, and pre-spinning means and adapted to receive and be responsive to rotational speed signals for controlling movement of coupling member between engaged and disengaged positions. | 08-28-2014 |
