Abstract: A focusing distance (e.g., a distance between a focal plane of a camera used when n image was captured and the actual focal plane for an in-focus image) in a visual analysis system may be determined by subjecting one or more images captured by such a system to a multi-layer analysis. In such an analysis, an input may be subjected to one or more convolution filters, and the ultimate result of such convolution may be provided to a dense layer which can provide the focusing distance. This focusing distance may then be used to (re) focus a camera or for other purposes (e.g., generating an alert).

Abstract: Techniques for the sensitive detection of analytes which combine the benefits of solution/suspension phase assay formats and the simplicity of solid phase/lateral flow assays are described. The assays can be performed in the solution/suspension phase using magnetic microspheres as a solid support. Subsequently a magnetic separation can be performed to separate the bound analyte from the remainder of the solution. After a wash step, the fluorescence signal can be directly read from the magnetic particle surface. Portable biodetection systems which employ fluorescent polymer superquenching and methods for detecting bioagents therewith are also described.
