20100122564 | Liquid sample evaporator for vapor analysis - Preparation methods for introducing liquid samples to gas analysis instruments include 1) complete evaporation of a liquid sample in a sample chamber, and 2) allowing the sample vapor in the sample chamber to equilibrate for a predetermined time. An inert carrier gas (e.g., dry nitrogen or zero air) is also admitted to the sample chamber. After equilibration, the sample vapor is admitted as a conditioned sample to an analysis instrument. Preferably, the predetermined equilibration time is sufficiently long that the sample vapor in the sample chamber becomes substantially homogeneous with respect to both concentration and isotopic ratio. Vapor derived from a liquid calibration standard in this manner can be employed as an accurate gas-phase calibration reference. | 05-20-2010 |

20100055802 | Analysis using separation combined with chemical conversion followed by optical spectroscopy - The present invention relates to the separation, quantitative measurement, and analysis of trace species using a combination of three steps in succession. First, trace species are separated from other species that are present. Second, the trace species are chemically modified to convert them into specific species that are advantageous for the third and final step. In this last step, cavity enhanced optical detection of the converted species is performed to detect and measure the concentrations of the species of interest. Because the last step has spectroscopic resolution, the concentration of isotopologues in each converted species can be determined. Further processing can provide the ratios between pairs of isotopologues, in particular the ratio of the rare isotopologues to the most abundant isotopologue. | 03-04-2010 |
20140026641 | Methods for gas leak detection and localization in populated areas using isotope ratio measurements - Improved gas leak detection from moving platforms is provided. Automatic horizontal spatial scale analysis can be performed in order to distinguish a leak from background levels of the measured gas. Source identification can be provided by using isotopic ratios and/or chemical tracers to distinguish gas leaks from other sources of the measured gas. Multi-point measurements combined with spatial analysis of the multi-point measurement results can provide leak source distance estimates. These methods can be practiced individually or in any combination. | 01-30-2014 |

20150047416 | Scanned 1-D Gas Plume Profile and Flux Measurements Using Multiple Analysis Instruments - A gas concentration image (i.e., concentration vs. position data) in a cross section through a gas plume is obtained. Such measurements can be obtained by moving a 1D array of gas sample inlets through the gas plume. By combining a gas concentration image with ambient flow information through the surface of the gas concentration image, the leak rate (i.e., gas flux) from the leak source can be estimated. Multiple gas analysis instruments can be employed in connection with sweeping a 1-D array of measurement ports through the gas plume in order to reduce analysis time. | 02-19-2015 |

20130253365 | APPARATUS AND METHOD FOR TREATMENT OF PAIN WITH BODY IMPEDANCE ANALYZER - A patient treatment unit and method analyzes and treats pain in tissues by applying an electrical pulse train to the affected tissue. The impedance of the affected tissue is measured, and the measured impedance is correlated to a level of pain in the patient. The pulse train is further applied in response to the measured impedance to reduce the patient's pain. The patient treatment unit includes a probe stimulus generator that outputs the pulse train. The treatment unit also includes a pair of probes for contacting the patient's body and receiving the pulse train. The pulse has improved shaping based on isolation of high voltage from a low voltage control. The unit further includes a body impedance analysis circuit that senses voltage and current via the probes when the probes are contacting the patient and observe the impedance. A monitor is electrically coupled to the body impedance analysis circuit and provides an indication of the measured impedance indicative of the patient's level of pain in real-time. | 09-26-2013 |

20110166622 | SPHERICAL VIBRATING PROBE APPARATUS AND METHOD FOR CONDUCTING EFFICACY ANALYSIS OF PAIN TREATMENT USING PROBE APPARATUS - A patient treatment unit and method analyzes and treats pain in tissues by applying an electrical pulse train and a galvanically isolated stimulus voltage to affected tissues using vibrating spherical tip probes. A range of probe diameters is used to provide a range of applied current densities. The impedance of the affected tissue is measured, tracked, and correlated to a level of pain while treatment is in progress. Impedance is used as real-time feedback, and current and voltage applications are adjusted accordingly. A patient treatment unit includes a probe stimulus generator connected to the spherically tipped probes. The unit further includes an impedance analysis circuit that senses voltage and current via the probes when they are contacting the patient. A monitor is electrically coupled to the body impedance analysis circuit and provides an indication of the measured impedance indicative of the patient's level of pain. | 07-07-2011 |

20150013099 | AUTOMATIC LARGE SURFACE CLEANING MACHINE - The apparatus consists of liquid/gas reservoirs and a movable reciprocating outlet nozzle connected to a pressure pump and connected to a vacuum unit, all of which are mounted on a small movable machine and all of which are driven by one engine of the small movable machine. The pressure pump is connected in some fashion to the drive shaft of the engine such that the power of the surface cleaning system automatically adjusts depending on machine speed. Also the nozzle systems sucks dirty liquid or dirt collected from the liquid/gas through a filter into a trash receptacle and moves the clean liquid into the mounted reservoir for use again by the pressure pump. | 01-15-2015 |

20110080021 | Quick Mounting for Protective Plates for Vehicles - Using multiple hook-type anchor bolts the user can quickly mount and remove a protective plate on or under vehicles by hooking onto the frame and/or parts of the body of the vehicle. Hook-type anchor bolt mounting avoids costly, labor-intensive, complex, and risky drilling into the body and/or frame of the vehicle as required by conventional mounting process requiring bolt holes to be drilled into the frame and/or body of the vehicle and secured by bolts. With this new method of mounting a protective plate the user can mount or remove a protective plate in a few minutes instead of taking 2 hours or more. This new method also avoids the need to disassemble parts of the vehicle to drill the mounting holes in remote locations on the frame and/or body of the vehicle. | 04-07-2011 |
