20160033159 | AIR FLOW MIXER - An air flow mixer that mixes two or more air streams that may enter air moving equipment at significantly different temperatures. In particular, methods, systems and apparatuses are disclosed that are directed to an air flow mixer that is structured and arranged to promote cross flow of portions of the air streams relative to each other through the air flow mixer. The cross flow resulting from the structure and arrangement of the air flow mixer avoids sharp delineations or fluid borders between the air streams that can be caused, for example, by a relatively higher temperature of one of the air streams and a relatively lower temperature of another one of the air streams. | 02-04-2016 |

20150325055 | DISPLAY APPARATUS - The present invention relates to a compact display apparatus providing similarly sized but much brighter virtual 3D images to a viewer, the apparatus comprising an enclosure; LED illumination based electronic display device; partially transparent and partially reflective viewing surface; and contrast/interference filter screen. The enclosure houses the LED illumination based electronic display device, filter screen and the partially transparent and partially reflective viewing surface. The filter screen is positioned close to the surface of the LED illumination based electronic display device. The LED illumination based electronic display device projects a primary real image onto the filter screen and is optically transmitted onto the partially transparent and partially reflective viewing surface. The partially transparent and partially reflective viewing surface reflects a secondary virtual 3D image perceivable on the opposite side of the partially transparent and partially reflective viewing surface to the LED illumination based electronic display device. | 11-12-2015 |

20150039452 | Consolidated Retailer-Operated Electronic Payment System - A consolidated electronic payment system operated by a retailer exclusively for its customers is disclosed. Otherwise independent and limited authentication and payment resources are consolidated within the unified system, facilitating broader access at retail checkout to several payment instruments. System functions are executed jointly by a customer-facing checkout facility and backend network resources comprising an authentication agent and a payment processor. Individual customers registered within the system are assigned a primary customer account, which is recorded within the network's data storage facility. Associated with these accounts are all available payment instruments and certain existing authentication accounts. For retail transactions, personal identification information and payment instructions submitted by the customer are transmitted to the network from checkout, with pertinent authentication and payment signals generated and transmitted back in response thereto. | 02-05-2015 |

20080201133 | SYSTEM AND METHOD FOR SEMANTIC CATEGORIZATION - There is disclosed a system and method for automatically performing semantic categorization. In one embodiment at least one text description pertaining to a category set is accepted along with words that are anticipated to be uttered by a user pertaining to that category set; lexical chaining confidence score is attached to each pair matched between the anticipated words and the accepted text description. These confidence scores are used subsequently by a categorization circuit that accepts a text phrase utterance from an input source along with a category set pertaining to the accepted utterance. The categorization circuit, in one embodiment, creates word pairs matched between the accepted text phrase utterance and the accepted category set. From these word scores, the category pertaining to the utterance is determined based, at least in part, on the assigned lexical chaining confidence scores as previously determined. | 08-21-2008 |

20130262175 | RANKING OF JOBS AND JOB APPLICANTS - A ranking system ranks applicants for a job. Eligible applicants are selected from a pool of applicants and are ranked based on business rules applied to information about the eligible applicants and information about the job. Scores are calculated for the business rules based on how well the applicant information matches the job information in areas such job skills, educational background, availability and pay. Additional information such as whether an employer or applicant does not wish to work together, and staffing firm expenses associated with eligible applicants can also be considered in the ranking process. The business rules can be weighted to achieve various ranking objectives, such as increasing staffing firm revenue or awarding higher rankings to applicants whose skills and educational background better match an employer's needs. The ranking system can also be used to rank jobs for an applicant. | 10-03-2013 |

20130181231 | MICROPIPE-FREE SILICON CARBIDE AND RELATED METHOD OF MANUFACTURE - Micropipe-free, single crystal, silicon carbide (SiC) and related methods of manufacture are disclosed. The SiC is grown by placing a source material and seed material on a seed holder in a reaction crucible of the sublimation system, wherein constituent components of the sublimation system including the source material, reaction crucible, and seed holder are substantially free from unintentional impurities. By controlling growth temperature, growth pressure, SiC sublimation flux and composition, and a temperature gradient between the source material and the seed material or the SiC crystal growing on the seed material during the PVT process, micropipe-inducing process instabilities are eliminated and micropipe-free SiC crystal is grown on the seed material. | 07-18-2013 |
