  • Patent number: 11988626
    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 compensates at least 50% of the total error in the output signal with a primary function and compensates a portion of the remaining error with a residual function. The amount of error compensation provided by the primary and residual functions may be adjusted with a weighing coefficient. The compensation method including a primary function and a residual function may be used to determine analyte concentrations having improved accuracy from output signals including components attributable to error.

  • Patent number: 10060874
    Abstract: Systems and methods for detecting dried test strips are provided, where a dried test strip may be one that has been re-inoculated with a biological sample after having already been previously inoculated with another sample at an earlier time (e.g., hours or days before). In various aspects, a biosensor such as an amperometric glucose biosensor (“meter”) may apply one or more input electrical signals to an inoculated test strip having at least a pair of electrodes in contact with the biological sample. The meter may measure output current value(s) resulting in response to the input electrical signals applied to the test strip. The meter may determine whether the test strip is a dried test strip by comparing a ratio of the measured output current value(s) with a boundary ratio value.

  • Patent number: 8649997
    Abstract: A system for a meter configured to determine an analyte concentration of a fluid sample includes a housing and a temperature sensor disposed within the housing. The system also includes a processor configured to receive temperature data from the temperature sensor upon the meter entering one of a charge state and a discharge state. The processor is further configured to predict a temperature value that approximates the ambient temperature outside of the housing. The predicted temperature value is based on historical temperature data received from the temperature sensor such that the predicted temperature value remains constant if a recently received temperature value remains within predetermined upper and lower temperature thresholds and the recently received temperature value exceeds the at least one predicted temperature value.

  • Patent number: 8614097
    Abstract: An assembly determines an analyte concentration in a sample of body fluid. The assembly includes a test sensor having a fluid-receiving area for receiving a sample of body fluid, where the fluid-receiving area contains a reagent that produces a measurable reaction with an analyte in the sample. The assembly also includes a meter having a port or opening configured to receive the test sensor; a measurement system configured to determine a measurement of the reaction between the reagent and the analyte; and a temperature-measuring system configured to determine a measurement of the test-sensor temperature when the test sensor is received into the opening. The meter determines a concentration of the analyte in the sample according to the measurement of the reaction and the measurement of the test-sensor temperature.
