Abstract:
Systems and methods are provided herein for improving the selectivity and productivity of sensors via digital signal processing techniques. According to one illustrative embodiment, in an electrochemical method for monitoring of a select analyte in a mixed sample with an interfering analyte, an improvement is provided that includes applying a large amplitude potential stimulus waveform to the sample to generate a nonlinear current signal; and resolving a signal contribution from the select analyte in the generated signal by a vector projection method with an analyte vector comprising a plurality of real and imaginary parts of one or more Fourier coefficients at one or more frequencies of a reference current signal for the select analyte.

Abstract:
Methods and apparatuses are provided for assembling a structure on a support having a pattern of binding sites. In accordance with the method, a first fluid is provided on the surface of the support with the first fluid being of a type that that increases viscosity when heated, the first fluid having first micro-components suspended therein each adapted to engage the binding sites. The first fluid proximate to selected binding sites is heated to increase the viscosity of the responsive fluid proximate to the selected binding sites so that the first micro-components suspended in the first fluid are inhibited from engaging the selected binding sites.

Abstract:
A support and a method for fluidic assembly are provided. The support has a surface having binding sites adapted to receive micro-components of a type that are applied to the surface using a fluid; and energy absorbing heat producers at selected binding site. Each energy absorbing heat producer is adapted to receive energy and to transduce a portion of the received energy to heat the fluid proximate to the selected binding sites; so that when the micro-components are applied using a fluid that increases viscosity when heated, the heat generated by the energy absorbing heat producers increases the viscosity of the fluid proximate to the selected binding sites to prevent the micro-components from attaching to the selected binding sites.
Abstract:
A method of transferring organic material from a donor element to a substrate includes providing a radiation source; and selecting the power of the radiation applied to the donor element by the radiation source to cause the transfer of organic material to the substrate wherein the time that one or more positions of the donor element receives radiation is greater than 1 millisecond.
Abstract:
A digital film grain (20) comprises a phototransistor (40) which produces an electrical signal having a strength which is related to an input radiation flux. A transponder receives commands and power from a base station (80) and transmits information quantifying the radiation observed by that digital film grain. An image accumulator (84) connected to the base station (80) assembles an image from the profile of radiation reported by a distribution of digital film grains correlated to the locations of those grains.
