20100255484SAMPLE PREPARATION CONTAINER AND METHOD - A system and method for preparing and collecting samples for analyte testing. The system can include a sample preparation system and a sample collection system coupled to the sample preparation system. The sample preparation system can include at least one of a deformable self-supporting receptacle comprising a reservoir and a freestanding receptacle comprising a reservoir. The reservoir can be adapted to contain a liquid composition. The sample collection system can be positioned in fluid communication with a reservoir of the sample preparation system, and can be adapted to capture an analyte of interest. The method can include providing a fluid path defined at least partially by the sample preparation system and the sample collection system, positioning the liquid composition in a reservoir of the sample preparation system, and moving at least a portion of the liquid composition in the fluid path to the sample collection system.10-07-2010
20100285520SAMPLE PREPARATION FOR ENVIRONMENTAL SAMPLING - A system and method for preparing samples to test an environmental surface for an analyte of interest. The system can include a deformable self-supporting receptacle comprising a reservoir, and a loaded substrate positioned in the reservoir of the deformable self-supporting receptacle. The loaded substrate can include a substrate and a source collected from the surface. The method can include combining the loaded substrate and a diluent in the reservoir, and agitating the loaded substrate and the diluent to form a liquid composition comprising the source and the diluent.11-11-2010

20110094943MAGNETIC SEPARATOR - There are provided devices, systems and processes to treat slurries that include magnetic and nonmagnetic particles suspended in water in such a fashion as to separate certain valuable elements and/or minerals from less valuable minerals or elements. A high intensity magnetic separator includes at least one large rotatable turntable that defines at least one circular channel therethrough in which a matrix material is positioned. The turntable is configured to rotate in a generally horizontal plane about a generally vertical virtual axis, causing the at least one circular channel to rotate through a plurality of intermittent magnetic and nonmagnetic zones generated by a plurality of permanent magnet members. A treatment slurry is directed into the channel or channels in one or more of the magnetic zones as the turntable rotates. A tailings fraction passes through the channel or channels in a generally downward direction in the magnetic zones and is collected in tailings launders. Magnetic particles are attracted to the matrix material in the magnetic zones and remain in the channel until it passes into an adjacent nonmagnetic zone, where the magnetic particles are washed form the channel into concentrate launders.04-28-2011

20090222760Method, System and Computer Program Product for Automating the Selection and Ordering of Column Data in a Table for a User - A method, system, and computer program product for automating the selection and ordering of column data in a table for a user are presented. In an exemplary manner, when a selected column is received, at least one available column related to the selected column is automatically recommended for display in an active table view. In response to the selected column being placed in the automatic data manipulation mode, a manipulation relationship between the selected column and the available column(s) is identified. When the selected column is manipulated (e.g., sorted, filtered), the available column(s) related to the selected column are automatically manipulated. The related available column(s) that are automatically recommended are concurrently displayed and grouped with the selected column in an active table view. Moreover, if a sort relationship exists between the available column(s) and the manipulated selected column, the related available column(s) are displayed according to the sort relationship.09-03-2009
20090259930Dynamically Selecting Properties to Display in a Table Based User Interface - Dynamically selecting which properties to display for a group of resources is provided. A selection of a group of resources is received to be viewed in a graphical user interface. A determination is made as to whether the group of resources is one of a plurality of previously saved groups of resources. Responsive to the group of resources being one of the plurality of previously saved groups of resources, a determination is made as to whether the previously saved group of resources has an associated saved group of properties. Responsive to the previously saved group of resources having the associated saved group of properties, a table is generated that comprises the previously saved group of resources and the associated saved group of properties. The table is then displayed to a user via a graphical user interface.10-15-2009

20080320120APPARATUS AND METHOD FOR VISUALIZATION OF WEB SERVICES DISTRIBUTED MANAGEMENT (WSDM) RESOURCES - An apparatus and method provides visualization of IT resources that are exposed as WSDM resources. A management system with a console provides visibility and functionality for WSDM resources by employing a visualization mechanism that processes standardized visualization metadata that is sent from a WSDM resource. The visualization mechanism uses standardized information to enable the management system console to display a robust presentation of the resource without needing to update the management system and console code when new types of resources are added.12-25-2008
20090327319HYBRID DATA MODEL AND USER INTERACTION FOR DATA SETS IN A USER INTERFACE - A first data model in which a large dataset is stored is maintained, wherein a first set of operations is allowed to be performed on the first data model. The first data model is reduced to a second data model that is of a smaller size than the first data model. Selected operations of the first set of operations are restricted from being performed on the second data model. A second set of operations is performed on the second data model, wherein the second set of operations is a subset of the first set of operations, and wherein the second set of operations does not include the selected operations that have been restricted from being performed on the second data model.12-31-2009
