  • Publication number: 20070281369
    Abstract: Detection systems and methods for detecting target biological analytes within sample material using acousto-mechanical energy generated by a sensor are disclosed. The acousto-mechanical energy may be provided using an acousto-mechanical sensor, e.g., a surface acoustic wave sensor such as, e.g., a shear horizontal surface acoustic wave sensor (e.g., a LSH-SAW sensor). A variety of techniques for modifying the effective mass of the target biological analytes in sample material are disclosed, including fractionating or disassembling the target biological analytes in the sample material (e.g., lysing the target biological analyte), adding a detectable mass to the target biological analyte or enhancing coupling of the target biological analyte (e.g., through the use of magnetic particles), exposing the sample material to a reagent that causes a change in at least detectable physical property in the sample material if the target biological analyte is present (e.g.

  • Publication number: 20070245810
    Abstract: Detection cartridges and associated components, as well as methods of using the same that provide sample materials to a sensor for detection are disclosed. Among the components that may be used in connection with the detection cartridges of the present invention are, e.g., input modules, fluid flow front control features, and volumetric flow rate control features. The modules may include one or more chambers containing different constituents for mixing and/or delivery into a detection cartridge.

  • Publication number: 20070212266
    Abstract: The present invention provides a detection article including at least one fluid control film layer having at least one microstructured major surface with a plurality of microchannels therein. The microchannels are configured for uninterrupted fluid flow of a fluid sample throughout the article. The film layer includes an acquisition zone for drawing the fluid sample into the plurality of microchannels at least by spontaneous fluid transport. The film layer also includes a detection zone having at least one detection element that facilitates detection of a characteristic of the fluid sample within at least one microchannel of the detection zone. The detection article may be formed from a plurality of film layers that are stacked to form a three-dimensional article.

  • Publication number: 20060141328
    Abstract: A flexible flow field separator includes a substrate layer formed of a flexible material and having first and second surfaces. A structured flow field pattern is defined on the first surface of the substrate layer. The structured flow field pattern defines one or more fluid channels. The separator includes a first layer formed of one or more metals and disposed on the first surface of the substrate layer. The first layer is formed of an electrically conductive material. The separator further includes a second layer disposed on the second surface of the substrate layer. The second layer is formed of a flexible electrically conductive material. The first layer contacts the second layer at one or more locations to define an electrical connection between the first and second layers.

  • Publication number: 20050203919
    Abstract: A data optimization method transforms an input Data File containing an Arbitrary Order Signal Sequence into a Streamable Signal Sequence having the same or compatible format as the original input Data File. The Streamable Signal Sequence, which represents the same information as contained in the original Arbitrary Order Signal Sequence, can be sequentially processed using less memory. In one embodiment, a Data File containing a PDF (portable document format) file, i.e., an Arbitrary Order Signal Sequence document is transformed from an arbitrary order organization into a Streamable Signal Sequence organization, more suitable for printing. Reordering an Arbitrary Order Signal Sequence into a Streamable Signal Sequence reduces the memory required to print a document as compared to the same document represented by an Arbitrary Order Signal Sequence.
