20140324362 | SHIFT CORRECTION FOR SPECTRAL ANALYSIS - Techniques are described for resolving and identifying peaks of signal intensity in mass chromatograms so that the peaks may be associated with components (e.g., chemical and/or ionic species) representative of an analysis sample to identify the components. The techniques facilitate correction of shift errors in the peaks of signal intensity of the mass chromatograms. | 10-30-2014 |
20140274751 | CHEMICAL IDENTIFICATION USING A CHROMATOGRAPHY RETENTION INDEX - Provided herein is technology relating to identifying unknown compounds and particularly, but not exclusively, to methods and systems for identifying unknown compounds by gas chromatography-mass spectrometry by use of retention index as a second dimension for identification. | 09-18-2014 |
20140260536 | MASS SPECTROMETRY (MS) IDENTIFICATION ALGORITHM - A system includes a gas chromatograph configured to determine experimental chromatographic data including retention times associated with samples. The system also includes a mass spectrometer configured to determine experimental mass spectral data associated with samples. The mass spectrometer can include a quadrupole field ion trap that uses a non-classical detection technique. The system. determines a retention index for an unknown sample based upon retention times for a calibration sample and the unknown sample, and identifies reference mass spectral data using the retention index. The reference mass spectral data can include spectra measured using a classical detection technique. The system can compare the experimental mass spectral data to the reference mass spectral data using one or more comparison metrics, such as a percent fragment match and/or a variance match. A score can be determined to identify the unknown sample using one or more of the metrics. | 09-18-2014 |
20140252234 | TRANSMISSION RAMAN SAMPLE ANALYSIS - Systems and methods for analyzing samples in containers are provided, where an emitter emits radiation at a first location on the container, with a portion of the radiation passing through the container and into the sample, some of the radiation is reflected within the container, a detector receives a transmission Raman signal including Raman radiation from multiple portions of the sample, and a comparator compares the transmission Raman signal with the radiation emitted by the emitter. | 09-11-2014 |
20130335737 | ELECTRICALLY-AUGMENTED DAMPING - Provided herein are devices, systems, and methods for electrically-augmented damping of an actuator and associated devices. In particular, electrically-augmented damping derived from measurement of voltage across an actuator and current flowing through an actuator is provided. | 12-19-2013 |
20130159544 | METHOD AND SYSTEM FOR MULTICAST DELIVERY OF MULTIMEDIA CONTENT ON DEMAND - A server in connection with a plurality of multimedia sources that has a plurality of clients. The server determines if at least one of the clients is requesting to receive at least one of the sources. The server then multicasts these requested sources to the requesting clients, respectively. If none of the clients is requesting a particular source, the server does not multicast that particular source. If all of the clients cease requesting a particular source that the server is currently multicasting, the server terminates the multicast of that particular source. | 06-20-2013 |
20130158881 | AUTONOMOUS MONITORING METHOD AND SYSTEM USING SENSORS OF DIFFERENT SENSITIVITIES - A method and system of monitoring for chemical or other toxic agents includes operating a plurality of first type sensors having a first level of sensitivity to an agent in a monitored area. Concurrently a second type sensor is operated having a second level of sensitivity to the agent in the monitored area, where the second level of sensitivity is at least ten times more sensitive than the first level of sensitivity. Input from the plurality of first type sensors and the second type sensor is received and analyzed, at a central location, in order to determine the presence of the agent in the monitored area. | 06-20-2013 |
20130046485 | MULTI-DETECTOR GAS IDENTIFICATION SYSTEM - A novel gas analysis system and method of identifying analytes in a gas sample are provided. The system uses multiple gas analysis technologies and uses the combined qualitative and quantitative data obtained from the multiple gas analysis technologies to analyze a gas sample. | 02-21-2013 |
20120133933 | METHOD FOR REDUCING LOSS OF ELECTROMAGNETIC RADIATION IN DETECTION APPLICATIONS - The application provides a method for reducing the loss of electromagnetic radiation caused by passing electromagnetic radiation through material with a rough surface. The method comprises applying a surface layer, such as a liquid or plastic film, to the material. The surface layer masks or decreases the surface irregularities or effects therefrom resulting in decreased loss of electromagnetic energy. | 05-31-2012 |
20120100526 | IDENTIFICATION AND DIFFERENTIATION OF NUCLEIC ACID SEQUENCE USING TEMPERATURE-DEPENDENT HYBRIDIZATION - Oligonucleotide probes are provided that are capable of hybridizing to different target nucleic acid sequences in a temperature-dependent manner allowing for detection of more than one target sequence by the same probe or by different probes having reporter labels with identical or similar detection characteristics. Also provided is a method for detecting target nucleic acid sequences using an oligonucleotide probe capable of hybridizing to the sequences in a temperature-dependent manner or using different probes having reporter labels with identical or similar detection characteristics. | 04-26-2012 |
20110246086 | OPTICAL RESISTANCE COUPLED APPARATUS AND METHOD - A method and apparatus for detecting a particular chemical in a sample, includes placing the sample in contact with a semiconductive material provided on a flow cell. An electrical characteristic of the semiconductive material is detected by an interdigitated electrode, and a first signal indicative thereof of output. An optical characteristic of the semiconductive material is detected by a photodetector and a second signal indicative thereof is output. Based on the first and second signals, it is determined by a processor as to whether or not the particular chemical is present in the sample. | 10-06-2011 |
