Abstract: The subject invention provides methods and assays for multiplexed detection of analytes using nanocrystals that are uniform in morphology, size, and composition based on their unique optical characteristics. The described methods and assays are particularly useful for detection of microbes and/or microbe-based agents in a complex environmental sample.

Abstract: A system for monitoring and analyzing data in a distributed process control system is provided. The system includes a user interface having a set of user controls for selecting and configuring data blocks to create a data diagram representing a data model. The data blocks are associated with data operations, such as data analytics functions, and may be configured by the user for particular instances of general blocks. The data blocks are interconnected by wires conveying outputs or inputs of the blocks, which may also connect data sources to the data blocks. The data sources may include on-line data (i.e., data streams) or off-line data (i.e., stored data) from the process control system. Additional user controls may be used to evaluate the data diagram or convert the data diagram from an off-line to an on-line version.

Abstract: A technique is provided for providing early fault detection using process control data generated by control devices in a process plant. The technique determines a leading indicator of a condition within the process plant, such as a fault, abnormality, or decrease in performance. The leading indicator may be determined using principal component analysis. A process signal indicating a process variable corresponding to the leading indicator is then obtained and analyzed. A rolling fast Fourier transform (FFT) may be performed on the process signal to generate time-series data with which to monitor the process plant. When the presence of the leading indicator is detected in the time-series data, an alert or other prediction of the condition may be generated. Thus, process faults may be identified using fluctuations and abnormalities as leading predictors.

Abstract: A data analytics service for performing data analytics functions within a distributed process control environment is provided. The service may provide a user interface for creating a first diagram, representing a data model. The first diagram may be configured, compiled, and evaluated using off-line (i.e., historical) data from a distributed process control system, which may include data stored in distributed data engines (DDEs). Following evaluation, the first diagram may be automatically converted into a second diagram that is bound to on-line (i.e., real-time) data sources within the process control environment, which may then be compiled and executed to generate performance or predictive analytics data for the process. The diagrams may comprise a plurality of configurable function blocks or modules, connected logically via wires conveying outputs or inputs of the blocks or modules.

Abstract: Distributed industrial process monitoring and analytics systems and methods are provided for operation within a process plant. A plurality of distributed data engines (DDEs) may be embedded within the process plant to collect and store data generated by data sources, such as process controllers. Thus, the data may be stored in a distributed manner in the DDEs embedded throughout the process plant. The DDEs may be connected by a data analytics network to facilitate data transmission by subscription or query. The DDEs may be configured as a plurality of clusters, which may further include local and centralized clusters. The local clusters may obtain streaming data from data sources and stream selected data to a data consumer. The centralized cluster may register the local clusters, receive data therefrom, and perform data analytic functions on the received data. The analyzed data may be further sent to a data consumer.

Abstract: Techniques for requesting and providing process plant data using a source-independent standardized query are provided. A requesting device generates a standardized query to obtain data from one or more data sources, such as relational or non-relational databases. The query utilizes a standardized format that does not depend upon the data source, which query may be generated as a JSON file. The standardized query may not be directly usable for any data sources. Instead, a data device generates one or more source-specific queries upon receipt of the standardized query. The source-specific queries utilize syntax native to each data source to obtain data. In some instances, the received data must be further processed to adjust for different sample times or sampling rates, such as by interpolation. The resulting data from all data sources may be aggregated into a data frame prior to being returned to the requesting device.

Abstract: A method for communicating between a surface containing a rare-earth oxide phosphor, which emits a second wavelength photon when excited by a first wavelength photon, and an article mounted on a device, wherein the method includes exciting the phosphor with a source that emits a first wavelength photon to produce a second wavelength photon response in the surface; and detecting the second wavelength photon with a means in communication with the article, wherein the article is capable of emitting a signal based upon receipt of the second wavelength photon.

Abstract: A method for inducing a visible light response in a material comprising combining an up-conversion phosphor, which emits visible light wavelengths when stimulated by non-coherent infrared wavelengths, with the material and activating the phosphor with a source that emits non-coherent infrared wavelengths to produce a visible-light response in the material.

Abstract: An air spring suspension damper assembly includes a first housing and a second housing which telescope relative to each other. An actuating member such as a cable is connected to a height leveling valve contained in one of the housings and attached to the other housing. The actuating member moves a member such as a rotating cam, a rotating valve plate and/or a rotating valve such that changes in the suspension height rotate the member. Rotation of the member selectively opens inlet and exhaust flow paths to control the air pressure in the damper assembly and maintain air suspension height at a predetermined height.

Abstract: An inexpensive breathable protective outer garment is produced from a breathable laminated fabric having a breathable film adhesively bonded to a nonwoven fabric. The film constitutes the outer layer of the garment and the nonwoven layer is on the inside. The seams of the garment are ultrasonically bonded such that the film sides of the laminate are in contact with each other during seaming.

Abstract: Enhanced barrier protection for rear closure surgical gowns is provided by improved garment pattern design. The surgical gown of the present invention is formed from a garment blank having a first part, a center part and a second part wherein the first part and the second part are joined to the center part. The first part includes a pair of side edges spaced apart by a bottom edge. The second part includes a pair of side edges spaced apart by an upper edge. The upper edge of the second part is of greater length than the bottom edge of the first part. Portions of the center part define a neck opening. The side edges of the second part extend inwardly from the upper edge towards the center part. A slit, defined by edges in the second part, extends from the upper edge to the neck opining. In this way, when joining the side edges of the first and second parts to from the surgical gown, portions of the second part near the edges defining the slit overlap.

Abstract: A combination luggage case, stand to remove contents without stooping over, a table with an extension that can be used as an ironing board or a display table. It has an open topped compartment and a hinged cover for the compartment. Foldable supporting structure includes a fork shaped support for one end and a nose panel for a support in position when opened parallel to the fork shaped support on the other end, thereby forming a stand to remove the contents or to be used as a table. The second position is made by raising the nose to be horizontal and parallel to the floor and supported by an auxiliary leg structure on the nose panel and the case, thus forming an extension table or to be used as an ironing board.
