20150127595 | MODELING AND DETECTION OF ANOMALY BASED ON PREDICTION - Embodiments relate to determining likelihood of presence of anomaly in a target system based on the accuracy of the predictions. A predictive model makes predictions based at least on the input data from the target system that change over time. The accuracy of the predictions over time is determined by comparing actual values against predictions for these actual values. The accuracy of the predictions is analyzed to generate an anomaly model indicating anticipated changes in the accuracy of predictions made by the predictive model. When the accuracy of subsequent predictions does not match the range or distribution as anticipated by the anomaly model, a determination can be made that the target system is likely in an anomalous state. | 05-07-2015 |

20120228236 | PHOTOCHEMICAL PURIFICATION OF FLUIDS - Apparatus and methods for the photochemical purification of fluids are disclosed. Fluids containing organic, inorganic and/or microbiological contaminants are treated by photochemical processes in a hybrid photoreactor incorporating a photocatalyst bonded to a light transmissive fiber substrate within at least a portion of the fluid and light sources to illuminate the fluid and photocatalyst. Photochemical processes include photocatalytic oxidation, photocatalytic reduction, photoadsorption, photolysis and photodisinfection. Some aspects of the disclosure include optimization of distribution of photocatalyst within the fluid, optimization of mass transport of contaminants by distribution of randomly-oriented fiber substrate, optimization of photoefficiency by control of light source wavelengths, use of LEDs to achieve optimized light source wavelengths, optimization of light delivery from light sources to fluid, and use of a microprocessor to optimize system performance. | 09-13-2012 |

20130118995 | SOLAR-ACTIVATED PHOTOCHEMICAL PURIFICATION OF FLUIDS - Disclosed herein are embodiments of a solar-activated photochemical fluid treatment system, some of which comprise a fluid vessel, a porous enclosure positioned inside of the fluid vessel, a porous enclosure positioned inside of the fluid vessel, a fiber substrate contained within the enclosure, and a semiconductor photocatalyst coupled to the fiber substrate. The fluid vessel can be configured to contain a fluid in contact with the photocatalyst such that the fluid treatment system, responsive to solar radiation applied to the photocatalyst and to the fluid in the vessel, induces photochemical modification of contaminants and living organisms in the fluid. Related methods are also disclosed. | 05-16-2013 |
