Patent number: 11091790Abstract: A biosensor system determines an analyte concentration of a biological sample using an electrochemical process without Cottrell decay. The biosensor system generates an output signal having a transient decay, where the output signal is not inversely proportional to the square root of the time. The transient decay is greater or less than the ?0.5 decay constant of a Cottrell decay. The transient decay may result from a relatively short incubation period, relatively small sample reservoir volumes, relatively small distances between electrode surfaces and the lid of the sensor strip, and/or relatively short excitations in relation to the average initial thickness of the reagent layer. The biosensor system determines the analyte concentration from the output signal having a transient decay.Type: GrantFiled: December 14, 2018Date of Patent: August 17, 2021Assignee: ASCENSIA DIABETES CARE HOLDINGS AGInventors: Huan-Ping Wu, Steven C. Charlton, Amy H. Chu, Andrew J. Edelbrock, Sung-Kwon Jung, Dijia Huang

Patent number: 10921278Abstract: 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.Type: GrantFiled: May 22, 2018Date of Patent: February 16, 2021Assignee: Ascensia Diabetes Care Holdings AGInventors: Dijia Huang, Huan-Ping Wu

Patent number: RE45384Abstract: An electrochemical test sensor adapted to assist in determining the concentration of analyte in a fluid sample is disclosed. The sensor comprises a base that assists in forming an opening for introducing the fluid sample, a working electrode being coupled to the base, and a counter electrode being coupled to the base, the counter electrode and the working electrode being adapted to be in electrical communication with a detector of electrical current, and a sub-element being coupled to the base. A major portion of the counter electrode is located downstream relative to the opening and at least a portion of the working electrode. The sub-element is located upstream relative to the working electrode such that when electrical communication occurs between only the sub-element and the working electrode there is insufficient flow of electrical current through the detector to determine the concentration of the analyte in the fluid sample.Type: GrantFiled: September 9, 2013Date of Patent: February 24, 2015Assignee: Bayer HealthCare LLCInventors: Matthew K. Musho, J. Oakey Noell, Andrew J. Edelbrock, Dijia Huang
