Publication number: 20220378337Abstract: In implementations of adaptive systems for continuous glucose monitoring (CGM), a computing device implements an adaptive system to receive glucose data describing user glucose values measured by a sensor of a CGM system, the sensor is inserted at an insertion site. The adaptive system accesses orientation data describing forces measured by an accelerometer of the CGM system, and the adaptive system identifies a location of the insertion site based on the orientation data. Modified glucose data is generated by modifying the user glucose values based on the location of the insertion site. The adaptive system generates an indication of the modified glucose data for display in a user interface of a display device.Type: ApplicationFiled: May 17, 2022Publication date: December 1, 2022Applicant: Dexcom, Inc.Inventors: Stephen Vanslyke, Arturo Garcia, Andrew Parker, Peter Simpson, Leif Bowman, David Price, Richard Kelley, Zebediah McDaniel, Andrew Pal, Nicholas Polytaridis, Sumi Mikami, Apurv Kamath, Lauren Jepson

Publication number: 20220202319Abstract: Meal and activity logging with a glucose monitoring interface is described. A glucose monitoring application is configured to display a user interface that includes a glucose graph that plots glucose measurements of a user over time. The glucose measurements, for example, may be obtained from a glucose monitoring device that collects glucose measurements of the user at predetermined intervals, e.g., every five minutes. Unlike conventional event logging approaches, the glucose monitoring application displays representations of logged events in the user interface along with the glucose graph. The logged events, for example, may include meals consumed by the user, and/or various activities performed by the user, such as exercise, meditation, sleep, and so forth. Notably, the glucose monitoring application controls the display of the event representations to be presented at positions on the glucose graph that correspond to times associated with the respective events.Type: ApplicationFiled: December 20, 2021Publication date: June 30, 2022Applicant: DexCom, Inc.Inventors: Margaret A.

Publication number: 20220202320Abstract: User interfaces for glucose insight presentation are leveraged. A glucose monitoring application is configured to process glucose measurements to determine one or more glucose insights, e.g., about a user's glucose. The glucose measurements, for example, may be obtained from a glucose monitoring device that collects glucose measurements of the user at predetermined intervals, e.g., every five minutes. The glucose monitoring application configures a user interface, based on configuration data, to present one or more visual elements representative of the one or more glucose insights. For example, the glucose monitoring application may configure the user interface to include a visual element in the form of a color field which represents whether the user's current glucose measurement (e.g., the most recent glucose measurement obtained from the glucose monitoring device) is below, within, or above a glucose range.Type: ApplicationFiled: December 28, 2021Publication date: June 30, 2022Applicant: DexCom, Inc.Inventors: Alexander Michael Diener, Stacey Fischer, Shaw Strothers, Justin Yuen, Chad Patterson, Apurv Kamath, Drew Terry, Margaret A.

Patent number: 9585607Abstract: Systems and methods for minimizing or eliminating transient non-glucose related signal noise due to non-glucose rate limiting phenomenon such as interfering species, ischemia, pH changes, temperatures changes, known or unknown sources of mechanical, electrical and/or biochemical noise, and the like. The system monitors a data stream from a glucose sensor and detects signal artifacts that have higher amplitude than electronic or diffusion-related system noise. The system processes some or the entire data stream continually or intermittently based at least in part on whether the signal artifact event has occurred.Type: GrantFiled: April 4, 2012Date of Patent: March 7, 2017Assignee: DexCom, Inc.Inventors: Apurv Kamath, James H.

Patent number: 7996071Abstract: Cardiac methods and devices that separate signals using at least two composite signals acquired at least at two input impedances. A target source impedance may be selected, and a cardiac signal may be separated from composite signals using the selected target source impedance. Medical systems include a cardiac device having a housing that provides amplification circuitry configured to have a first amplifier input impedance and a second amplifier input impedance, such as using two separate circuits or switching between two input impedances. One or more electrode assemblies are coupled to the amplification circuitry. A signal processor is provided in the housing configured to separate a source signal using a first composite signal detected at the first input impedance and a second composite signal detected at the second input impedance. The phase response of the first input amplifier circuit is about equal to that of the second input amplifier circuit.Type: GrantFiled: June 30, 2009Date of Patent: August 9, 2011Assignee: Cardiac Pacemakers, Inc.Inventors: Apurv Kamath, Darrel Orvin Wagner, Paul Haefner, Marina Brockway
