Publication number: 20240040348Abstract: Embodiments described herein include a data receiving device for an analyte monitoring system. The data receiving device detects a disconnect between the data receiving device and a sensor control device of the analyte monitoring system. The data receiving device sets a duration of a scan window for receiving connection data packets from the sensor control device to a current length and initiates the scan window. In response to determining that a connection between the data receiving device and sensor control device has not been established based on connection data packets received during the scan window, the data receiving device performs iterations of a process to adjust the scan window, involving increasing a duration of the scan window to a new length that is greater than the current length and initiating the scan window based on the duration of the scan window at the new length.Type: ApplicationFiled: July 18, 2023Publication date: February 1, 2024Applicant: ABBOTT DIABETES CARE INC.Inventors: Xuandong Hua, Danny Chan

Publication number: 20230281111Abstract: An application program stored in a ROM includes a function lookup data structure in which functions called by the application program have identifiers and memory addresses at which the function is located and can be executed. Upon startup, the function lookup data structure is copied to a RAM as a revised lookup data structure and is compared to a revision lookup data structure also written to that RAM or elsewhere. If the revision lookup data structure contains replacement functions having the same function identifiers but new memory addresses, these new memory addresses are written over the existing addresses in the revised lookup data structure for those replacement functions. The application program refers to the revised lookup data structure to find and execute the functions; thus the original application program on the ROM can continue to be used with revised functions.Type: ApplicationFiled: October 12, 2022Publication date: September 7, 2023Inventors: Xuandong Hua, Kurt Leno
