Patent number: 9344777Abstract: Methods, systems, and devices for short-range low-power wireless communication of analyte information are provided. In some implementations, short-range low-power wireless communication of analyte information may include receiving an electromagnetic wireless communication signal and harvesting energy from the electromagnetic wireless communication signal. In some implementations, short-range low-power wireless communication of analyte information may include enabling capabilities associated with an external sensor in response to detecting the external sensor. In some implementations, short-range low-power wireless communication of analyte information may include detecting an analyte sample; determining an analyte concentration associated with the detected analyte sample; and transmitting an indication of the analyte concentration to an external device.Type: GrantFiled: December 20, 2012Date of Patent: May 17, 2016Assignee: ABBOTT DIABETES CARE INC.Inventors: Lei Lawrence He, Marc B. Taub

Patent number: 9317657Abstract: An embodiment may be in the field of glycemic analysis and control. More specifically, an embodiment or approach may provide a novel method, system, and computer program for the visual and quantitative tracking of blood glucose variability in diabetes from self-monitoring blood glucose (SMBG) data and/or continuous glucose monitoring (CGM) data. More particularly, an embodiment or aspects thereof may use glucose measurements obtained from self-monitoring data and/or CGM data of an individual or a group of individuals to track and analyze blood glucose variability.Type: GrantFiled: November 24, 2009Date of Patent: April 19, 2016Assignee: University of Virginia Patent FoundationInventors: Marc D. Breton, Boris P. Kovatchev

Patent number: 9316609Abstract: A sensor utilizing a non-leachable or diffusible redox mediator is described. The sensor includes a sample chamber to hold a sample in electrolytic contact with a working electrode, and in at least some instances, the sensor also contains a non-leachable or a diffusible second electron transfer agent. The sensor and/or the methods used produce a sensor signal in response to the analyte that can be distinguished from a background signal caused by the mediator. The invention can be used to determine the concentration of a biomolecule, such as glucose or lactate, in a biological fluid, such as blood or serum, using techniques such as coulometry, amperometry, and potentiometry. An enzyme capable of catalyzing the electrooxidation or electroreduction of the biomolecule is typically provided as a second electron transfer agent.Type: GrantFiled: May 19, 2014Date of Patent: April 19, 2016Assignee: Abbott Diabetes Care Inc.Inventors: Benjamin J. Feldman, Adam Heller, Ephraim Heller, Fei Mao, Joseph A. Vivolo, Jeffery V. Funderburk, Fredric C. Colman, Rajesh Krishnan

Patent number: 9289164Abstract: Generally, methods, devices, and systems for generating a hybrid analyte level output are provided. The uncompensated analyte levels lag in time with respect to the lag-compensated analyte levels, and the hybrid analyte level output tracks between the uncompensated analyte levels and the lag-compensated analyte levels according to predetermined criteria.Type: GrantFiled: June 29, 2012Date of Patent: March 22, 2016Assignee: Abbott Diabetes Care Inc.Inventor: Gary A. Hayter
