Patent number: 7935499Abstract: The invention relates generally to methods, systems, and devices for measuring the concentration of target analytes present in a biological system using a series of measurements obtained from a monitoring system and a Mixtures of Experts (MOE) algorithm. In one embodiment, the present invention describes a method for measuring blood glucose in a subject.Type: GrantFiled: June 30, 2008Date of Patent: May 3, 2011Assignee: Animas CorporationInventors: Timothy C Dunn, Yalia Jayalakshmi, Ronald T Kurnik, Matthew J Lesho, Jonathan James Oliver, Russell O Potts, Janet A Tamada, Steven Richard Waterhouse, Charles W Wei

Patent number: 7699775Abstract: The present invention relates to methods to increase the number of analyte-related signals used to provide analyte measurement values, e.g., when two or more analyte-related signals are used to obtain a single analyte measurement value a “rolling” value based on the two or more signals can be employed. In another aspect, interpolation and/or extrapolation methods are used to estimate unusable, missing or error-associated analyte-related signals. Further, interpolation and extrapolation of values are employed in another aspect of the invention that reduces the incident of failed calibrations. Further, the invention relates to methods, which employ gradients and/or predictive algorithms, to provide an alert related to analyte values exceeding predetermined thresholds.Type: GrantFiled: October 13, 2004Date of Patent: April 20, 2010Assignee: Animas Technologies, LLCInventors: Shashi P. Desai, Timothy C. Dunn, Matthew J. Lesho, Russell O. Potts, Janet A. Tamada, Charles W. Wei

Patent number: 7024236Abstract: The present invention relates to methods of formulating analyte data databases, the databases themselves, and methods of manipulating the same. In one aspect the present invention includes the formulation of analyte data points, derived data, and data attributes databases comprising data points collected using an analyte monitoring device capable of frequent monitoring of analyte concentrations or amounts. Such data points may comprise acquired data (e.g., values corresponding to analyte concentrations or amounts as measured by said analyte monitoring device). These data points are then associated with one or more relevant data attributes. The resulting databases may be manipulated to determine relationships among the components of the database.Type: GrantFiled: April 8, 2004Date of Patent: April 4, 2006Assignee: Animas Technologies LLCInventors: Russell Ford, Matthew J. Lesho, Russell O. Potts, Michael J. Tierney, Charles W. Wei
