    摘要: An assay device is provided for use in determining the presence of a target analyte in a sample. The assay device comprises a solid platform comprising a fibrous mat, the solid platform impregnated with a first FRET chromophore. An antibody-FRET chromophore conjugate is immobilized on a surface of the solid platform, wherein the antibody-FRET chromophore conjugate comprises an antibody affixed to a second FRET chromophore. The first FRET chromophore and the second FRET chromophore are selected to provide an energy transfer from one to another when located within a Förster distance with respect to each other, thereby forming a FRET donor-acceptor chromophore pair. In a further aspect, a method of detecting a target analyte in a sample is provided. In yet a further aspect, packaging sheet materials and packaging articles employing the assay device under certain conditions are provided.

    摘要: Herein provided is a controller for a current inverter. The controller comprises a reference generator configured for obtaining source voltage and current values from an electrical source, generating a voltage error function based on source and reference voltages, and generating a current error function based on source and reference currents. The controller also comprises an output controller for receiving from the reference generator the voltage and current error functions and configured for producing at least one control signal based on the voltage and current error functions. The controller also comprises a state feedback controller configured for: adjusting the at least one control signal, based on parameters of the electrical source, to produce at least one adjusted control signal, and outputting the at least one adjusted control signal to the current inverter.

    摘要: Applicants have discovered a novel apparatus and method to aggregate and displace a plurality of magneto-responsive entities (steerable self-propelled entities or SSPEs) in three dimensions using time-multiplexing. The apparatus for controlling aggregation of SSPEs in a body comprises at least three sets of magnetic field sources arranged in three axes for generating a controlled magnetic field and a controller connected to at least one of said magnetic field sources to create a three dimensional convergence point. The method for aggregating the entities can comprise using a first set and a second set of said magnetic field sources to generate opposed magnetic field gradients in each said set to cause aggregation of said magneto-responsive entities in two axes and wherein the controller is configured to reverse a direction of said magnetic field gradient in a third set of magnetic field sources in a third axis according to a first predetermined program.
