20150050743 | METHOD AND DEVICE FOR SENSING HUMIDITY WITH REVERSIBLE MOLECULAR DIMERIZATION - The present invention relates to the use of reversible dimerization of methylene blue (MB) for sensing humidity. The invention preferably uses titanate nanowires coated with MB. The self-organizational properties of MB on the surface of this nanostructured material studied by spectroscopic means revealed that the light absorption properties of the MB molecules are humidity dependent. Based on the observed humidity dependent metachromasy, we fabricated a humidity sensor using optical fiber technology which is adapted for medical, industrial or environmental applications. The sensor operates with excellent linearity over the relative humidity (RH) levels ranging from 8 to 98%. The response and recovery time can be reduced to 0.5 s while the device exhibits excellent reproducibility with low hysteresis. These performances allow the implementation of the sensor in a breathing monitoring system. Furthermore, the metachromasy was observed for other dyes. This calls for a detailed study of molecular configuration on functional surfaces since it can substantially modify the sensitization efficacy of dyes, e.g. in light conversion. | 02-19-2015 |

20140220692 | EARLY WARNING SYSTEM FOR HYDRATE OR CLATHRATE MATERIALS - A method of detecting hydrate formation includes monitoring a gas phase of interest. The gas phase is a mixture of gases comprising at least one hydrate forming gas. The monitoring includes determining the concentration of at least one component of the mixture of gases, or determining a ratio of concentration between two components of the mixture, at least one of which is the hydrate forming gas. When a change in the determined concentration or in the determined ratio of concentration is detected, relative to an earlier determination or relative to a pre-established base level concentration or base level range of concentration then formation of a hydrate is indicated. Apparatus for carrying out the method and methods for estimating the location of hydrate formation in a pipeline are also described. | 08-07-2014 |
20150093833 | METHOD OF PRE-TREATING A FILTER USED IN A SMALL-SCALE WATER SEPAROMETER - The safety and proper performance of jet aircraft engines requires that any contamination of jet fuel, for example by water or by improper contaminants, be filtered (removed) before delivery of the fuel, through hoses, to the fuel tanks of the aircraft. Coalescing devices and filters in the fuel delivery system are used to attain this result. A typical problem is that filter materials chemically react with surfactants, and this causes the filter subsequently to “disarm” or fail to perform its function of removing water, which can lead to delivery of fuel containing excessive water. A solution to this problem is to pre-test the fuel for such surfactants by feeding a small fuel sample that has been mixed with “challenge water” through a smaller ‘representative’ test filter and monitor the performance. Using a fluorescent dye in the “challenge water,” the amount of water that passes the test filter is detected, compared with a baseline data and fuel quality determination is made. From the result of the small-scale test, the fuel condition can be inferred and, based thereon; action can be taken to treat the fuel, prior to further distribution, such that it will not disarm field filter-coalescers in a typical fuel distribution system. The use of a fluorescent dye enhances the ability to make this determination of very small representative fuel filters. The fuel evaluation process is fully automated, thereby avoiding human-factor variables and assuring repeatable results. | 04-02-2015 |
