Abstract: Biological activity in holding pens in a micro-fluidic device can be assayed by placing in the holding pens capture objects that bind a particular material of interest produced by the biological activity. The biological material of interest that binds to each capture object can then be assessed, either in the micro-fluidic device or after exporting the capture object from the micro-fluidic device. The assessment can be utilized to characterize the biological activity in each holding pen. The biological activity can be production of the biological material of interest. Thus, the biological activity can correspond to or arise from one or more biological cells. Biological cells within a holding pen can be clonal cell colonies. The biological activity of each clonal cell colony can be assayed while maintaining the clonal status of each colony.

Abstract: An electrical submersible pumping system (“ESP”) for use in a wellbore includes an electrical motor, a pump, a shaft coupled between the motor and pump, and a lubricant pump for circulating lubricant within the ESP. The lubricant pump includes a diffuser and an impeller that mounts onto and rotates with shaft rotation. A portion of the impeller has a frusto-conical outer surface, which is circumscribed by a portion of the diffuser profiled complementary to the frusto-conical portion of the impeller. The pump directs lubricant flow in a single direction irrespective of the rotational direction of the shaft.

Abstract: System and method for interfacing with digital 3D representations of real-world locations. Embodiments of the present invention are directed to allowing for remote monitoring and digital traversal of building or facility interiors with real-time GPS integration.

Abstract: A method is disclosed for evaluating a damaged blade in a compressor or turbine using a computer system accessing a database of blade repair information, where the method includes: selecting a blade damage geometry category corresponding to the damage of the blade from a plurality of blade damage geometry categories; measuring the blade damage, and generating a repair geometry for the blade based on the blade damage measurements and the selected blade damage geometry category.

Abstract: A method of cooling a person by evaporation, comprising providing a liquid-retaining composite material, and a bladder that stores a liquid; hydrating said multi-layered composite with a liquid; and employing said multi-layered, liquid-retaining composite material as a garment or a flat sheet and evaporatively cooling said person.
