20110277540 | Micro-Optical Sensor for Electric Field Detection - A novel micro-optical electric field sensor exploits morphology-dependent shifts of the optical modes of dielectric cavities to measure temporally- and spatially-resolved of electric field with extremely high sensitivity. The measurement principle is based on the electrostriction effect on the optical modes of dielectric micro-resonators (or micro-cavities) and exploits recent developments in optical fiber and switching technologies. The optical modes are commonly referred to as “whispering gallery modes” (WGM) or “morphology dependent resonances” (MDR). By monitoring the WGM shifts, the electric field causing the electrostriction effect can be determined. Different sensitivities and measurement ranges (maximum measured electric field) can be obtained by using different cavity geometries (for example solid or hollow spheres), polymeric materials (PMMA, PDMS, etc) as well as poling the dielectric material. | 11-17-2011 |

20130145823 | System and Method for Measuring the Concentration of Impurities Mixed with Hydrogen Gas - A system and method for taking a sample of hydrogen gas and conditioning that sample so that extremely low levels of contamination can be more accurately detected. Initially a sample of hydrogen gas is captured and isolated in a collection chamber. A hydrogen permeable membrane is provided having a first side and a second side. The first side of the hydrogen permeable membrane is exposed to the gas sample held within the collection chamber. The hydrogen gas contained within the gas sample begins to permeate through the hydrogen permeable membrane and exit the collection chamber. This causes the pressure of the gas sample within the collection chamber to decrease. Since contaminants remain in the collection chamber, the concentration of contaminants within the remaining sample increases exponentially. The residual pressure within the collection chamber is measured and converted into a contaminant level reading. | 06-13-2013 |

20140165705 | Sample Line Management In A Fluid Analyzer System - In a first mode, a monitoring system inputs humidified gas through at least a portion of a conduit. At least a portion of the water in the humidified gas adheres to the inner surface of the conduit, inhibiting contaminants in the gas sample from adhering to the inner surface. The water in the humidified gas may also push any contaminants adhered to the surface of the sample line back out the sample line. In a second mode, after previously passing the humidified gas through the conduit, the monitoring system controls a flow of a gas sample including the contaminants through the conduit to a gas analyzer. The one or more layer of water on the inner surface of the conduit prevents or reduces a buildup of undesirable contaminants on an inner surface of a conduit that conveys gas samples. | 06-19-2014 |

20150355069 | METHOD FOR MONITORING AND PURIFYING AIR - An air purifier is presented with a sensor controlling a motorized fan, wherein the sensor continuously and automatically adjusts the sensitivity setting of the sensor as the quality of air being purified changes. The average air quality readings of the air passing through an air purifier are monitored over a designated time period and, as the quality fluctuates, the sensitivity of the sensor is automatically adjusted. If the air quality is poor (i.e. a high particulate count), the sensitivity of the sensor will be adjusted to a less sensitive setting (i.e. allowing higher fan speeds so that more air can be moved through the filter) and, if the air quality is good (i.e. a low particulate count), the sensitivity of the sensor will be adjusted to a more sensitive setting (i.e. setting a lower maximum fan speed because not as much air needs to move through the filter). | 12-10-2015 |
