  • Patent number: 10852235
    Abstract: A fluorometer may be used to measure ultralow concentrations of fluorescing species, such as ultralow concentrations of fluorescent tracer passing through a reverse osmosis membrane into a permeate stream. In some examples, the fluorometer may be recalibrated by resetting some but not all of the calibration parameters used to determine the concentration of fluorescent tracer in the permeate based on the measured fluorescent response of the fluorometer. For example, an intercept of a calibration curve may be reset or recalibrated for the fluorometer in situ, potentially providing significant accuracy improvements even though the fluorometer has not undergone a full recalibration.

  • Patent number: 10088462
    Abstract: This document describes a gas sampling device. The gas sampling device is capable of housing sensors printed on thin film (e.g., paper) and is operable to expose the sensors printed on the thin film to air for a brief period of time to sample the air for smells. The exposure causes a chemical reaction between the sensors and the sampled air and differs depending on the smells of the sampled air. After exposure, an image of the reacted sensor is captured. The image is analyzed according to image processing techniques to recognize the smells of the sampled air. The gas sampling device is also capable of concurrently sampling air from a surrounding environment along with sampling air from a specimen of interest. By analyzing both samples, the smells of the specimen of interest can be distinguished from those of the surrounding environment. Once the smells are ascertained, a profile of chemical groups in gases of the sampled air is output.

  • Patent number: 8924024
    Abstract: A controller determines and adjusts system parameters, including cleanliness levels or sootblower operating settings, that are useful for maintaining the cleanliness of a fossil fuel boiler at an efficient level. Some embodiments use a direct controller to determine cleanliness levels and/or sootblower operating settings. Some embodiments use an indirect controller, with a system model, to determine cleanliness levels and/or sootblower settings. The controller may use a model that is, for example, a neural network, or a mass energy balance, or a genetically programmed model. The controller uses input about the actual performance or state of the boiler for adaptation. The controller may operate in conjunction with a sootblower optimization system that controls the actual settings of the sootblowers. The controller may coordinate cleanliness settings for multiple sootblowers and/or across a plurality of heat zones in the boiler.

  • Patent number: 8916097
    Abstract: A controller for an automated immunoassay system is provided to manage the system resources and control the flow of samples under test. The controller allows tests to be run dynamically instead of in a serial, first in first out flow. The controller evaluates the set of tests to be run and generates a sequencing strategy. The sequencing strategy is based on the paths specified for each type of assay, the numbers of tests to be run, the priority of each test and the resources required for each test. In addition, the controller can resolve resource allocation conflicts and modify the sequencing strategy as test conditions change during operation.

  • Patent number: 8850903
    Abstract: A liquid aspirating and dispensing apparatus and method of using the apparatus. Among other elements, the apparatus includes a liquid handling device having one or more channel members, each of which has a removable liquid holding tip attached, and a signal transmitting device. A signal transmitted from the signal transmitting device may be used in a variety of ways to yield information regarding the performance of the apparatus. This information may be provided via direct detection of the signal by an operator of the apparatus. Alternatively, the signal may be detected by a programmable signal detecting device, interpreted by the apparatus, and then displayed in a form that is understandable to the operator. Furthermore, the liquid holding tip may be modified to enable different forms of signal transmission.
