  • Publication number: 20190204258
    Abstract: Methods are disclosed for measuring an analyte concentration in a fluidic sample. Such methods further allow one to correct and/or compensate for confounding variables such as hematocrit (Hct), temperature or both before providing an analyte concentration. The measurement methods utilize information obtained from test sequences having at least one AC block and at least one pulsed DC block, where pulsed DC block includes at least one recovery potential, and where a closed circuit condition of the electrode system is maintained during the DC block. Also disclosed are devices, apparatuses and systems incorporating the various measurement methods.

  • Patent number: 10295494
    Abstract: Methods are disclosed for measuring an analyte concentration in a fluidic sample. Such methods allow one to correct and/or compensate for confounding variables such as hematocrit, salt concentration and/or temperature before providing an analyte concentration. The measurement methods use response information from a test sequence having at least one DC block, where DC block includes at least one excitation pulse and at least one recovery pulse, and where a closed circuit condition of an electrode system is maintained during the at least one recovery pulse. Information encoded in the excitation and recovery pulses are used to build within- and across-pulse descriptors to correct/compensate for hematocrit, salt concentration and/or temperature effects on the analyte concentration. Methods of transforming current response data also are disclosed. Further disclosed are devices, apparatuses and systems incorporating the various measurement methods.

  • Publication number: 20190102688
    Abstract: A method, device and system for estimating causality among observed variables are provided. The method for estimating causality among observed variables may include: in response to receiving expert knowledge for at least part of a plurality of observed variables, converting the expert knowledge into a constraint that needs to be satisfied by a causality objective function for the plurality of observed variables; and estimating the causality among the observed variables, by using observed data of the observed variables to optimally solve, through sparse causal reasoning, the causality objective function under a constraint of a directed acyclic graph and the constraint that needs to be satisfied and converted from the expert knowledge. With embodiments of the present disclosure, it is possible to incorporate the expert knowledge into the causal reasoning process in a simple manner to sufficiently utilize the expert knowledge and obtain a more precise causality.

  • Patent number: 10197524
    Abstract: Methods are disclosed for scaling body fluid analysis data to correct and/or compensate for confounding variables such as hematocrit (Hct), temperature, variations in electrode conductivity or combinations thereof before providing an analyte concentration. The scaling methods utilize current response data obtained from an AC block applied prior to a DC block to minimize the impact of such confounding variables upon the observed DC current response before creating descriptors or algorithms. The scaling methods therefore compensate the measured DC current by using data from the AC block made on the same sample. Also disclosed are devices, apparatuses and systems incorporating the various scaling methods.

  • Patent number: 9594045
    Abstract: Methods are disclosed for measuring an analyte concentration in a fluidic sample. Such methods further allow one to provide an error code or correct and/or compensate for interferents such as an antioxidant before providing an analyte concentration. The measurement methods utilize information obtained from test sequences having at least one DC block, such as a slow-ramped bi-polar waveform, where a closed circuit condition is maintained during the DC block. The methods use information relating to status of a redox mediator feature during the electrochemical analysis to provide an antioxidant failsafe if the antioxidant is interfering with the analyte concentration. Also disclosed are devices, apparatuses and systems incorporating the various measurement methods.
