  • Patent number: 10739350
    Abstract: A biosensor system determines analyte concentration from an output signal generated from a light-identifiable species or a redox reaction of the analyte. The biosensor system adjusts a correlation for determining analyte concentrations from output signals with one or more index functions extracted from the output signals. The index functions determine at least one slope deviation value, ?S, or normalized slope deviation from one or more error parameters. The slope-adjusted correlation between analyte concentrations and output signals may be used to determine analyte concentrations having improved accuracy and/or precision from output signals including components attributable to bias.

  • Patent number: 9459202
    Abstract: A collision-computing system detects and amplifies the energy associated with a feature signal to determine occurrences or absence of events, such as ultrasonic and/or geophysical events, or to determine presence and/or concentrations of substances such as blood glucose, toxic chemicals, etc., in a noisy, high-clutter environment or sample. To this end, a conditioned feature, obtained by modulating a carrier kernel with a feature signal, is collided with a Zyoton—a waveform that without a collision can travel substantially unperturbed in a propagation medium over a specified distance. The conditioned feature and the Zyoton are particularly constructed to be co-dependent in terms of their respective dispersion velocities and the divergence of a waveform resulting from the collision. The collision operation can transfer at least a portion of the feature energy to the resulting waveform, and the transferred energy can be amplified in successive collisions for detecting/measuring events/substances.

  • Patent number: 9164076
    Abstract: A biosensor system determines analyte concentration from analytic and/or secondary output signals. The biosensor system adjusts a correlation for determining analyte concentrations from output signals with one or more index functions extracted from the output signals. The index functions determine at least one slope deviation or normalized slope deviation from one or more error parameters. The slope-adjusted correlation between analyte concentrations and output signals may be used to determine analyte concentrations having improved accuracy and/or precision from output signals including components attributable to bias.

  • Patent number: 9114398
    Abstract: A method and device for digital multiplex PCR assays employ a microfluidic chip for performing real-time, continuous flow PCR within microchannels of the chip. A stream of sample material is introduced into each microchannel and alternating boluses of assay-specific reagents and buffer are introduced into the stream to form sequentially configured test boluses. A PCR procedure is performed on the test boluses followed by a thermal melt procedure. During the thermal melt procedure, fluorescent output is detected and fluorescence vs temperature data is collected and compared to expected normal correlations. The results, positive or negative, are converted to digital format, with positive results designated as “1” and negative results designated as “0”, or vice versa.
