20140072720 | PATTERNED NANOPARTICLE STRUCTURES - Aspects relate to patterned nanostructures having a feature size not including film thickness of below 5 microns. The patterned nanostructures are made up of nanoparticles having an average particle size of less than 100 nm. A nanoparticle composition, which, in some cases, includes a binder material, is applied to a substrate. A patterned mold used in concert with electromagnetic radiation function to manipulate the nanoparticle composition in forming the patterned nanostructure. In some embodiments, the patterned mold nanoimprints a suitable pattern on to the nanoparticle composition and the composition is cured through UV or thermal energy. Three-dimensional patterned nanostructures may be formed. A number of patterned nanostructure layers may be prepared and suitably joined together. In some cases, a patterned nanostructure may be formed as a layer that is releasable from the substrate upon which it is initially formed. Such releasable layers may, in turn, be arranged to form a three-dimensional patterned nanostructure in accordance with suitable applications. | 03-13-2014 |

20090063383 | Real-time reasoning system using natural language-like rules - A reasoning system with a reasoning engine that uses a rule set created from a rule representation language that has an English/natural language-like rule syntax and format is discussed. The reasoning system employs a real-time selection algorithm that chooses the rules used to analyze complex data (e.g.: bio-medical research, e-commerce, Customer Relationship Management (CRM), environmental research & engineering, bio-chemical research and product development, Investment and money management, anything related to research and product development) without suffering exponential performance decreases as the complexity of the analysis increases. The use of the rule representation language enables different domain users to review, create and modify rules without requiring the users to possess an advanced knowledge of programming languages. | 03-05-2009 |
