Publication number: 20240115215Abstract: A display device configured to receive raw values, calculate smoothed values, and display the smoothed values only if the smoothed values satisfy a consistency check. In some embodiments, the consistency check may be satisfied if none of the smoothed values (i) corresponds to a raw value that triggered a first or second alarm and (ii) would not also trigger the first or second alarm. In some embodiments, if the smoothed values do not satisfy the consistency check, the display device may re-calculate the smoothed values such that the consistency check is satisfied. The display device may display the smoothed values in place of corresponding raw values in a historical trend graph.Type: ApplicationFiled: December 1, 2023Publication date: April 11, 2024Applicant: Senseonics, IncorporatedInventors: Barbara MONTGOMERY, Kamuran TURKSOY, Alex MARKOVIC, Shang ZHAO, Andrew DEHENNIS, Samanwoy Ghosh DASTIDAR

Patent number: 11864892Abstract: Systems, methods, and apparatuses for reducing error between calculated analyte levels and impractical analyte measurements using practical analyte measurements as reference measurements for calibration. Reducing the error may include converting a practical reference analyte measurement into an estimated impractical analyte level, updating a conversion function using the estimated impractical analyte level, and using the updated conversion function to calculate an analyte level. In some embodiments, the practical reference analyte measurement may be a capillary blood analyte measurement, and the estimated impractical analyte level may be an estimated venous blood analyte level. In some embodiments, the updated conversion function may minimize the error between analyte levels calculated using the updated conversion function and estimated venous blood analyte levels.Type: GrantFiled: November 25, 2020Date of Patent: January 9, 2024Assignee: Senseonics, IncorporatedInventor: Kamuran Turksoy
