摘要:
An compact hydraulic manifold for transporting shear sensitive fluids is provided. A channel network can include a trunk and branch architecture coupled to a bifurcation architecture. Features such as tapered channel walls, curvatures and angles of channels, and zones of low fluid pressure can be used to reduce the size while maintaining wall shear rates within a narrow range. A hydraulic manifold can be coupled to a series of microfluidic layers to construct a compact microfluidic device.

In one embodiment, a storing and dispensing cap is provided and includes a housing movably couplable to a container neck having a lip, a dispensing platform coupled to the housing, and a dispenser opening between an exterior edge of the dispensing platform and the housing. The dispenser opening is configured to be plugged by the lip of the container neck when the housing is coupled to the container neck, and the dispenser opening is configured to be unplugged when the housing is not coupled to the container neck. A storing and mixing system including such a cap, and a method of storing and mixing using such a cap are also provided.

An embodiment of the invention is directed to a method and apparatus for automatically providing network services in a way that improves upon the prior art. Systems implementing aspects of the invention can, for instance, provide developers with a mechanism for creating Web Services without having to write low-level SOAP, XML, or WSDL code. The system utilizes a rule-based approach to provide a mechanism for dynamically reconfiguring the system with requiring redeployment of the entire system.
摘要:
A storing and mixing system having a container and a cap is presented. The container includes a reservoir and a neck having a lip. The cap removably couplable to the neck of the container and has: a housing movably couplable to the neck by engaging an interior screw thread of the housing with the neck; a dispensing platform coupled to the housing by a plurality of ribs; and a plurality of peripheral dispenser openings between an exterior edge of the dispensing platform and the housing. The plurality of dispenser openings is configured to be plugged or unplugged by the lip of the neck. In an axial direction of the neck, a length of the lip is larger than or equal to a length of the interior screw thread of the container. Optionally, there are provided contact surfaces between the cap and the container to seal the dispensing platform from the ambient environment and from the interior of the container, when the cap is securely screwed onto the container.

摘要:
The invention provides an interface assembly for delivering an ionized analyte from an ionization apparatus into an ion mobility spectrometer. This allows analysis of biological and non-biological samples, even non-volatile solids, via differential mobility spectrometry, without fragmentation of molecules. The invention also provides portable sample analysis systems that operate at ambient pressure. Systems of the invention may be used for high molecular weight species detection, for example, drinking water contaminants, pathogenic biological agents, bio-organic substances, non-biological material, peptides, proteins, oligonucleotides, polymers, bacteria, and hydrocarbons.
