摘要:
The present invention provides multiple-luminophore silica nanoparticles for multiplexed signaling in bioanalysis. In specific embodiments, two inorganic luminophores, Tris(2,2′-bipyridyl)osmium(II) bis(hexafluorophosphate) (OsBpy) and Tris(2,2′-bipyridyl)dichlororuthenium(II) hexahydrate (RuBpy), or three organic luminophores 5-Fluorescein isothiocyanate (5-FITC), 5-carboxyrhodamine 6G, succinimidyl ester (5-CR6G, SE), 6-carboxy-X-rhodamine, succinimidyl ester (6-ROX, SE) can be simultaneously entrapped inside silica nanoparticles at controlled ratios, with desirable sizes and required surface functionality. Single-wavelength excitation with multiple emission endows the nanoparticles with optical encoding capability for rapid and high-throughput multiplexed detection.
摘要:
An automatically-activated laser scanning 2-D bar code symbol reading system employing a visible linear-type laser scanning pattern and an audible feedback signal during scan data capturing and buffering operations. The system includes a laser scanning 2-D bar code symbol reading mechanism that automatically produces a visible linear-type laser scanning pattern for scanning a 2-D bar code symbol structure on an object as its hand-supportable housing is manually transported past a 2-D bar code symbol along a height-wise direction by an operator, automatically capturing lines of scan data from the scanned 2-D bar code symbol structure, decode processing the scan data, and generating a symbol character data string representative of the read 2-D bar code symbol.
摘要:
In one embodiment, an application integration system collects business application information and generates and stores certain business flow and state information for the application, its involved users and shared business content within the system. This automation process defines the collaboration models between the content, process and users involved in the collaboration project. The automation process uses specific information pertaining to the involved users and applications of the system, the process flows of the application program, and the shared content to automate the integration of the distributed computer applications by defining the integration flow as a process checkpoint flow consisting of numerous checkpoints through which the business content transitions. Users of the collaboration hub platform are provided with an interactive console within a graphical user interface presented on their respective computing devices. The displayed graphical user interface elements are generated based on the shared business content and process flows of the distributed applications comprising the integrated project.
摘要:
A wireless bar code symbol reading system for use in both vertical and horizontal orientations in a work environment. The system comprises a wireless hand-supportable bar code symbol reading device in two-way RF communication with a base station that is installable within a work environment and includes a base station housing having a cradle portion provided with a pair of hinged support hooks for supporting the hand-supportable housing of the reading device in both vertical and horizontal orientations. The pair of hinged support hooks are arrangeable in a protracted position within the cradle portion so as to support the hand-supportable housing in the cradle portion mounted in a vertical orientation. The pair of hinged support hooks are arrangeable in a retracted position within the cradle portion so as to support the hand-supportable housing in the cradle portion mounted in a horizontal orientation.

The present invention relates to human waste collection bags for babies, children or adults to be attached to a wearer. More particularly it relates to a flange (12) for a human waste collection bag comprising an inner periphery and an outer periphery, where the flange (12) comprises slits (13) extending to said inner periphery.
摘要:
Novel reactions used to prepare phosphole and bisphosphole compounds are detailed. Novel phosphole compounds and metal coordination compounds of phosphole and bisphosphole compounds are also provided. These metal coordination compounds are useful as catalysts for the polymerization or olefins with carbon monoxide and for the polymerization of acrylic monomers.
摘要:
Blends of two or more polyethylenes are made by reacting ethylene with an oligomerization catalyst that forms &agr;-olefins, and two polymerization catalysts, one of which under the process conditions copolymerizes ethylene and &agr;-olefins, and the other of which under process conditions does not readily copolymerize ethylene and &agr;-olefins. The blends may have improved physical properties and/or processing characteristics.
摘要:
An absorbent material comprising a mixture of (1) a plurality of absorbent gelling particles comprising a water-insoluble, water-swellable polymer, and (2) an absorbent property modification polymer reactive with at least one component included in a urine. The mixture is made by (i) applying a solution containing an organic solvent, water and the absorbent property modification polymer onto the plurality of absorbent gelling particles, wherein the weight ratio of the organic solvent to the water is at least 50:50, and (ii) removing a portion of the organic solvent and water from the applied absorbent gelling particles. When a urine is applied to the absorbent material, the absorbent gelling particles are spontaneously connective through the absorbent property modification polymer. The absorbent material has at least one of the improved absorbent properties after swelling such as (1) liquid permeability, (2) porosity, (3) wet integrity, and (4) recovery property when subjected to external forces.
