  • Publication number: 20160370262
    Abstract: A system includes an analysis system at a first location and one or more remote sampling systems at a second location remote from the first location. A sampling system can be configured to receive a remote liquid sample. The system also includes a sample transfer line configured to transport gas from the second location to the first location. The sample transfer line is configured to selectively couple with a remote sampling system for supplying a continuous liquid sample segment to the sample transfer line. The system can further include a sample receiving line at the first location. The sample receiving line is configured to selectively couple with the sample transfer line and the analysis system to receive the continuous liquid sample segment and supply the sample to an analysis device.

  • Patent number: 9523700
    Abstract: A sample identification system for an automated sampling and dispensing device is described. In an example implementation, the sample identification system includes a sample probe configured to contact a sample positioned within a sample vessel. Further, the sample identification system includes an identifier capture device configured to measure a sample identifier associated with the sample vessel and generate a data signal in response thereto, where the data signal corresponds to an identity of the at least one sample. During operation, the identifier capture device scans a sample holder, a sample vessel, or a table top of the automated sampling and dispensing device to measure the sample identifier and to generate the data signal in response thereto.

  • Publication number: 20160305917
    Abstract: Systems and methods are described to determine whether a sample transmitted through a transfer line from a remote sampling system contains a suitable sample to analyze by an analysis system. A system embodiment includes, but is not limited to, a sample receiving line configured to receive a liquid segment a first detector configured to detect the liquid segment at a first location in the sample receiving line; a second detector configured to detect the liquid segment at a second location in the sample receiving line downstream from the first location; and a controller configured to register a continuous liquid segment in the sample receiving line when the first detector and the second detector match detection states prior to the controller registering a change of state of the first detector.

  • Publication number: 20160296158
    Abstract: Multi-frequency Diffuse Photon Density Wave (DPDW) methodology at near infrared wavelengths is used to non-invasively measure the optical absorption and reduced scattering coefficients of tissue at depths of several millimeters to quantify the depth and degree of tissue damage. A digitally-controlled stepper motor and variable RF generator enable the user to select the distance between the light source and detector and the modulation frequency through software. This allows for the collection of virtually unlimited number of data points, enabling precise selection of the volume and depth of tissue that will be characterized.

  • Patent number: 9438145
    Abstract: A magnet temperature estimating system for a synchronous electric motor having a permanent magnet includes: a superimposing unit configured to superimpose a voltage or current of a frequency different from a frequency of a fundamental wave driving the synchronous electric motor on at least a d-axis of the synchronous electric motor; a calculator configured to calculate an impedance of the synchronous electric motor from the superimposed voltage or current and a current or voltage obtained by the superimposing; and a magnet temperature estimating unit configured to estimate a temperature of the permanent magnet on the basis of the calculated impedance.

  • Patent number: 9341229
    Abstract: A dampening device for an automated sampling/dispensing device is described. In an example implementation, the dampening device includes a cylindrical body. The cylindrical body includes a first end and a second end, a first opening being defined within the first end and a second opening being defined within the second end. Further, the cylindrical body may include an inner diameter greater than an outer diameter of an automated sampling/dispensing device sample probe. During operation, the dampening device moves out of phase with the automated sampling/dispensing device sample probe allowing sample probe vibrations to be dampened during operation. The dampening device is configured to be magnetically attracted to the sampling/dispensing device. For example, the dampening device and/or the sampling/dispensing device can include a permanent magnetic material, a ferromagnetic material, a ferrimagnetic material, and/or an electromagnet.

  • Patent number: 9277410
    Abstract: A method and a device for optimizing the assignation of network activity of a cellular communications network to land areas in a simple and accurate way. This technique allows representing the activity of a cellular network on a set of tiles in a grid covering a certain land area, instead of representing it associated to antenna cells that might or might not overlap. The activity dispersed and assigned to non-overlapping grid tiles is much simpler and clearer to understand and allows visualizing how the network activity is distributed over the space and how it varies along time allowing therefore an efficient network design and management optimization.

  • Patent number: 9159031
    Abstract: Various technologies described herein pertain to automatic prediction of an anticipated audience response for scripting. A sub-document unit can be received, where the sub-document unit can be part of a script. The sub-document unit, for example, can be a sentence, a paragraph, a scene, or substantially any other portion of the script. Content of the sub-document unit and a context of the sub-document unit can be analyzed to extract features of the sub-document unit. A predictive model can be employed to predict an anticipated audience response to the sub-document unit based upon the features of the sub-document unit. Moreover, the anticipated audience response to the sub-document unit predicted by the predictive model can be output.

  • Patent number: 8489590
    Abstract: Embodiments are directed towards generating market-specific ranking models by leveraging target market specific pairwise preference data. The pairwise preference data includes market-specific training examples, while a ranking model from another market captures the common characteristics of the resulting ranking model. In one embodiment, the ranking model is trained by applying a Tree Based Ranking Function Adaptation (TRADA) algorithm to multi-grade labeled training data, such as editorially generated training data. Then, contradictions between the TRADA generated ranking model and target-market specific pairwise preference data are identified. For each identified contradiction, new training data is generated to correct the contradiction. Then, in one embodiment, an algorithm such as TRADA is applied to the existing ranking model and the new training data to generate a new ranking model.

  • Patent number: 7690275
    Abstract: An enclosure for an automated sampling and/or dispensing device for minimizing contamination to samples enclosed therein. Further, the enclosure may minimize user exposure to the enclosed samples allowing for the containment of potentially hazardous chemicals. In an embodiment, the enclosure includes at least one flexible panel which allows a user to efficiently access the device by retracting the at least one flexible panel. In addition, the at least one flexible panel allows the enclosure to be shipped efficiently for the enclosure may be disassembled into smaller pieces and thus, be shipped in a smaller box when compared to enclosures with non-flexible panels/doors. Moreover, the use of the at least one flexible panel allows the enclosure to be shaped to accommodate varying shaped automated sampling and or dispensing devices and assemblies.
