| 20080302211 | LINEAR HEARTH FURNACE SYSTEM AND METHODS REGARDING SAME - Systems and methods for use in processing raw material (e.g., iron bearing material) include a linear furnace apparatus extending along a longitudinal axis between a charging end and a discharging end (e.g., the linear furnace apparatus includes at least a furnace zone positioned along the longitudinal axis). Raw material is provided into one or more separate or separable containers (e.g., trays) at the charging end of the linear furnace apparatus. The separate or separable containers are moved through at least the furnace zone and to the discharging end where the processed material is discharged resulting in one or more empty containers. One or more of the empty containers are returned to the charging end of the linear furnace apparatus to receive further raw material. | 12-11-2008 |
| 20080307960 | Air Pollutant Removal Using Magnetic Sorbent Particles - Absorbent magnetic particles are used to remove air pollutants. The adsorbent magnetic particles can adsorb various air pollutants, including nitrogen oxides, sulfur oxides, and mercury, and may be regenerated for reuse. | 12-18-2008 |
| 20100107818 | SYSTEM AND METHOD FOR PRODUCING METALLIC IRON NODULES - A method for producing metallic iron nodules by assembling a shielding entry system to introduce coarse carbonaceous material greater than 6 mesh in to the furnace atmosphere at location(s) where the temperature of the furnace atmosphere adjacent at least partially reduced reducible iron bearing material is between about 2200 and 2650° F. (1200 and 1450° C., the shielding entry system adapted to inhibit emission of infrared radiation from the furnace atmosphere and seal the furnace atmosphere from exterior atmosphere while introducing coarse carbonaceous material greater than 6 mesh into the furnace to be distributed over the at least partially reduced reducible iron bearing material, and heating the covered at least partially reduced reducible iron bearing material in a fusion atmosphere to assist in fusion and inhibit reoxidation of the reduced material during fusion to assist in fusion and inhibit reoxidation of the reduced material in forming metallic iron nodules. | 05-06-2010 |

| 20110100162 | METHOD AND SYSTEM FOR PRODUCING METALLIC IRON NUGGETS - A method and system for producing metallic iron nuggets may include providing multiple layers of agglomerates, such as briquettes, balls and extrusions, of a reducible mixture of reducing material (such as carbonaceous material) and of a reducible iron bearing material (such as iron oxide) on a hearth material layer (such as carbonaceous material) and providing a coarse overlayer of carbonaceous material over at least some of the agglomerates. Heating the agglomerates of reducible mixture to 1425° C. or 1400° C. or 1375° C. results in formation of an intermediate product of one or more metallic iron nuggets, which may have a sulfur content of less than 0.03%, and slag, which may have less than 5% mass MgO, which may have a ratio of percent by weight sulfur in the slag over percent by weight sulfur in the metallic nuggets of at least about 12 or at least about 15. | 05-05-2011 |

| 20090045317 | OPTICAL CAVITY EMITTER ARRANGEMENTS WITH SPECTRAL ALIGNMENT AND METHODS THEREFOR - Aspects of the disclosure are directed to optical microcavities and emitters that are spectrally aligned in an arrangement having an array of such microcavity-emitter combinations. The spectral alignment can be selective, in that a portion of the array of microcavity-emitter combinations, or a single microcavity-emitter combination, can be individually spectrally aligned. In specific examples, light is coupled within a semiconductor device having wavelength-dependent structures and optical cavities optically couple to the wavelength-dependent structures. One of the optical cavities and a wavelength-dependent structure are spectrally aligned, independent of another of the optical cavities. | 02-19-2009 |

| 20100119193 | Ultrafast and ultralow threshold single emitter optical switch - Electrical control of the emitter of a coupled quantum emitter-resonant cavity structure is provided. Electrodes are disposed near a semiconductor quantum dot coupled to a semiconductor optical cavity such that varying an applied bias at the electrodes alters an electric field at the quantum dot. Optical input and output ports are coupled to the cavity, and an optical response of the device relates light emitted from the output port to light provided to the input port. Altering the applied bias at the electrodes is capable of altering the optical response. Preferably, the closest electrode to the cavity is disposed between or away from angular lobes of the cavity mode, to reduce loss caused by the proximity of electrode to cavity. The present approach is applicable to both waveguide-coupled devices and non-waveguide devices. | 05-13-2010 |

| 20110231272 | Retail mobile point-of-sale (POS) software application and retail middleware software application - A portable electronic device includes a memory and processor. The memory stores instructions, which are part of a retail mobile software purchase software application. The instructions, which when executed by the processor cause the portable electronic device to first transmit a search request for an item. The device receives item information including item description and item price and also receives a selection to purchase the item from a purchaser. The retail mobile software creates an order including the selected item and adds other selected items to the order. The retail mobile software application displays payment options for the order and receives a payment option selection for the order including the selected item. The retail mobile software application receives payment confirmation for the order including the selected item and displays receipt options for the order including the selected item. The retail mobile software application receives a selection of a receipt option and generates an electronic receipt for the order. | 09-22-2011 |

| 20110184588 | SYSTEM AND METHOD FOR ESTIMATING AND DETECTING SPEED - A system for determining instances when a vehicle's indicated speed exceeds a governing speed includes a receiver to receive information from which a vehicle's location envelope, indicated direction of travel, and indicated speed can be derived, and a processor. The processer is configured to ascertain a location envelope in which the vehicle is located, an indicated speed of the vehicle, and a direction of travel of the vehicle at a sample time. It is also configured to select the governing speed for the vehicle at the sample time, which includes ascertaining possible road segments with at least a portion within the location envelope, eliminating road segments with a road segment direction of travel inconsistent with the indicated direction of travel, and selecting as the governing speed a speed associated with a remaining road segment. The processor will then determine if the indicated speed exceeds the governing speed. | 07-28-2011 |

| 20090015101 | Embedded circuits on an ultrasound transducer and method of manufacture - One or more chips, integrated circuits, or semiconductors are embedded within a backing block. Planar sheets of backing material are formed with integrated circuits within holes in the sheets. Traces connect the integrated circuit to electrodes or exposed conductive surfaces. A plurality of the planar sheets may be manufactured using wafer processing, such as pick and place of chips in a wafer of backing material and IC redistribution for forming the traces. The different sheets are cut from the wafer and stacked adjacent each other. The transducer connects with the exposed electrodes or conductive surfaces of the backing. | 01-15-2009 |
