| 20130321824 | Optical Detection of Airfoil Axial Position with NSMS - A method for determining axial location of rotor blades is provided. The method may monitor an output signal of a sensor configured to detect the proximity of the rotor blades, wherein at least one of the rotor blades being marked with a position marker that is configured to cause a recognizable inconsistency in the output signal only when the rotor blades rotate at a known default axial position. The method may further determine the axial displacement of the rotor blades if the inconsistency is not detected in the output signal for at least one full revolution of the rotor blades. | 12-05-2013 |
| 20140269817 | Phosphor Thermometry Fiber Sensor - A high precision phosphor temperature sensor is disclosed. The sensor includes a light source that emits an excitation light through a first optical fiber to a Y-coupler or splitter that connects the first optical fiber to a second optical fiber and a third optical fiber. The second optical fiber connects the Y-coupler to a detector and the third optical fiber connects the Y-coupler to a sensing end of the third optical fiber that is coated with a phosphor that produces a fluorescent emission when engaged by excitation light generated by the light source. The third optical fiber then transmits fluorescent emissions from the phosphor through the Y-coupler whereby at least some of the fluorescent emission passes through the second optical fiber to the detector. The lifetime of the fluorescent emission can be measured and the temperature at the phosphor can be calculated from said lifetime. | 09-18-2014 |

| 20110177772 | VAPOR REMOVAL SYSTEM - An apparatus for the evacuation of warm, moist air or vapor from a dishwasher cabinet or other washing machine interior. A centrifugal fan draws the hot air and water vapor out of the washing cavity through a flue riser and discharges it into a cooling chamber with one or more cooling spray nozzles. The cooling spray nozzles spray a fine mist of cold water into the stream of heated air and vapor, and may spray at angle to the flow of the stream of heated air and vapor. As the heated air and vapor from the dishwasher and the cooling spray mix, heat is transferred from the heated air and vapor to the cold water or mist being sprayed into the air stream. This reduces the temperature of the vapors and air that was extracted from the dishwasher. As the temperature is reduced, the water vapors condense and form droplets which accumulate on the sides and bottom of the cooling flue. This reduced temperature and moisture air is then discharged to the room at an opening, which may be located slightly above the bottom of the flue cabinet, along with the condensate. | 07-21-2011 |
| 20120186614 | ADDITIVE ALERT SYSTEM - An apparatus and system for detecting the delivery or nondelivery of a cleaning and sanitizing agent or chemical in automated dishwashers, warewashers, and laundry machines. A detector comprising one or more sensors or two or more electrical electrodes are positioned outside the ends of the delivery tube or tubes for the sanitizing agent or chemical. As the sanitizing agent or chemical liquid is released from the delivery tube or tubes, the liquid forms a stream of flow through the air. The flow passes within sensing range of the sensor or sensors, or encompasses the electrical electrodes thereby completing an electrical circuit. When the sensor detects the flow and the sensor is activated, or the circuit completes, a control unit prevents an alarm from sounding. | 07-26-2012 |

| 20140052285 | METHOD FOR SPECIFYING AND FABRICATING AN OBJECT, ASSOCIATED APPARATUS, AND APPLICATIONS - A method for specifying and fabricating non-homogeneous, anisotropic, truly functionally graded objects. The objects may have defined spatial heterogeneity (e.g., a gradient in material concentration) with local randomized distributions. This local randomness is designed in such a way that global averaging results in the specified spatial heterogeneity. The fabrication of structures is an additive process in which a material is deposited in defined patterns. | 02-20-2014 |

| 20090014056 | Micro concentrators elastically coupled with spherical photovoltaic cells - With small dimensional optics, small photovoltaic cells have heat distribution surfaces, very high concentrations and subsequently high utilization of the semiconductors can be achieved. Discrete photodiodes can be formed as spherical and other geometric shaped, cells with high performance characteristics, precision dimensions, and low cost. This invention positions discrete photovoltaic cells by using their geometric shape, elastic electrical mounts, couples them to small optical concentrator systems of refractory and or reflective optics and makes electrical network connections to those photodiodes, reliably, adjusting for thermal expansion, and at low cost to form low cost and reliable electrical power arrays. The electrical connectors and network can form part of the reflective optics and heat removal system. The electrical interconnection system can also form a reliable network that is self-correcting and tolerant of point failures. | 01-15-2009 |

| 20120231138 | Field-Ready Oven - A field-ready oven has reinforced telescoped side walls that extend and hold a base, shelf, tray support and cover spaced apart. A low air intake and a semipermeable membrane deliver air and vapor fuel to catalyst pads on the shelf. Radiant heat from exothermic reaction is diffused over a bottom of a tray. Hot gas circulates around the diffuser and tray with a chimney effect before exhausting. A lid on the cover lifts for access to the tray. A fuel container in the oven forces fuel through a capillary restriction to limit fuel flow. A spring in the container is released to start fuel flow. | 09-13-2012 |

| 20140290720 | Photovoltaic Module Mounting to Rubber Tires - A photovoltaic panel mounting system utilizes rubber tires to anchor and position photovoltaic panels to face the sun and resist wind forces. The shaded interior cavity of the rubber tires physically and thermally protects electronics and batteries. The tires may be filled with soil, concrete, water, or aggregate to provide further ballasting, enabling a photovoltaic mount system to withstand high velocity winds. Telescoping conduits may house wiring for the system and allow for resizing and reshaping of the mounting system. The mounting system decreases used tire waste and provides low cost components and portability. | 10-02-2014 |

| 20090189479 | Brush Assembly - A brush assembly is provided that facilitates a longer usable brush life and permits easy brush assembly replacement. The brush assembly includes an arc-shaped brush and a pivot arm, with the mounting end of the arc-shaped brush bound or otherwise mounted with respect to one end of the pivot arm. The end of the pivot arm that is not bound to the arc-shaped brush typically includes a female cylindrical slot for mating with a male shaft that is prefabricated in the motor housing, parallel to the rotor's axis. When the disclosed brush assembly is installed into an electric motor, the pivot arm slot is slidably positioned onto the shaft in the motor housing, enabling the brush assembly to pivot about the shaft on a plane that is perpendicular to the rotor's axis of rotation. A biasing spring force impels the brush assembly to pivot inward toward the rotor in the longitudinal direction of the brush, and maintains the operating end of the arc-shaped brush in contact with the rotating faces of the commutator. A single biasing spring is adapted to act upon both the brush and an interrupter device that is activated when the brush life is exhausted. | 07-30-2009 |
