Patent number: 9766198Abstract: Testing of the performance of an electrochemical meter used to measure the presence of an analyte in a biological sample, particularly glucose in whole blood, includes introducing a control solution containing a predetermined amount of the analyte and a predetermined amount of an internal reference compound. The internal reference compound is selected such that it is oxidized at a potential greater than that used to oxidize the analyte, thereby making it possible to distinguish the control solution from a biological sample.Type: GrantFiled: December 10, 2015Date of Patent: September 19, 2017Assignee: ASCENSIA DIABETES CARE HOLDINGS AGInventors: Greg P. Beer, Huan-Ping Wu

Patent number: 9658188Abstract: An electrochemical test sensor includes a lid and a base. The base has a length and a width. The length of the base is greater than the width of the base. The base includes at least a working electrode, a counter electrode and at least three test-sensor contacts for electrically connecting to a meter. The at least three test-sensor contacts are spaced along the length of the base from each other. The base and the lid assist in forming a fluid chamber for receiving the fluid sample. The electrochemical test sensor further includes a reagent to assist in determining the concentration of the analyte in the fluid sample.Type: GrantFiled: February 11, 2014Date of Patent: May 23, 2017Assignee: Ascensia Diabetes Care Holdings AGInventors: Greg P. Beer, John P. Creaven

Patent number: 8877035Abstract: A sensor system, device, and methods for determining the concentration of an analyte in a sample is described. Gated amperometric pulse sequences including multiple duty cycles of sequential excitations and relaxations may provide a shorter analysis time and/or improve the accuracy and/or precision of the analysis. The disclosed gated amperometric pulse sequences may reduce analysis errors arising from the hematocrit effect, variance in cap-gap volumes, non-steady-state conditions, mediator background, under-fill, temperature changes in the sample, and a single set of calibration constants.Type: GrantFiled: March 28, 2013Date of Patent: November 4, 2014Assignee: Bayer HealthCare LLCInventors: Huan-Ping Wu, Christine D.
