Patent number: 10846605Abstract: An approach for detecting a transient error in a body fluid sample based on the shape of a response curve of a sensor is provided. The response curve is represented by an equation including at least one coefficient describing a curvature or slope of the response curve. The approach includes comparing the coefficient to a range of coefficients which includes coefficients of response curves corresponding to known analyte concentrations. The approach further includes detecting a transient error based on the comparison. In some examples of the approach, the comparison and detection are performed by a processing transient error detector executing computer readable instructions embodied in a non-transitory computer-readable medium. Other examples of the approach determine a concentration of the analyte based on the equation. Advantageously, various examples of the approach can expedite detection of transient errors at the time of measuring and before reporting sample result.Type: GrantFiled: January 22, 2018Date of Patent: November 24, 2020Assignee: Instrumentation Laboratory CompanyInventors: Sohrab Mansouri, Jose Maria Cervera

Patent number: 9910966Abstract: Technologies for increasing sample throughput by predicting the end point response time of a sensor for the analysis of an analyte in a sample are disclosed. In one aspect, a system includes a sensor that generates data signals associated with the measurement of an analyte within the sample. A processor records appropriate data points corresponding to the signals, converts them to a logarithmic function of time scale, and plots the converted data points. The processor then determines a curve that fits the plotted data points and determines a curve fitting equation for the curve. Once the equation is determined, the processor extrapolates an end point response of the sensor using the equation. A value, such as analyte concentration, is then calculated using the extrapolated end point response.Type: GrantFiled: July 16, 2015Date of Patent: March 6, 2018Assignee: Instruments Laboratory CompanyInventors: Sohrab Mansouri, Jose Maria Cervera, Ashley Moraski
