Abstract: An analyte monitoring system including an analyte sensor, a transceiver, and a display device. The transceiver may be configured to (i) receive measurement information from the analyte sensor, (ii) calculate an analyte concentrations using at least the measurement information, and (iii) convey the calculated analyte concentration. The display device may be configured to (i) receive the analyte concentration from the transceiver, (ii) receive one or more user selections for font or display-related settings, and (iii) display the received analyte concentration using default font or display-related settings that are different than the one or more user selections. The display device may be configured to compare the one or more received user selections to font or display-related criteria and display the received analyte concentration using the different default font or display-related settings in response to determining that the one or more received user selections do not meet the criteria.

Abstract: A system and method of extending the life of a battery. The system may include a display device and a transceiver. The transceiver may include the battery. The transceiver may be configured to perform a battery level reading function to determine a battery level of the battery. The transceiver may be configured to time performance of the battery level reading function such that it does not occur at the same time as a period of high current demand on the battery. The transceiver may be capable of executing concurrently two or more of the functions, and the transceiver may be configured to avoid executing concurrently one or more of: (a) a number of functions greater than a maximum number of functions; (b) functions including one or more high current demand functions; and (c) two or more functions that would have a combined current demand higher than a current demand threshold.

Abstract: An analyte monitoring system may include a display device configured to (i) receive and display analyte concentrations, (ii) select one of a plurality of meal types as a default meal type based on the current time of day, and (iii) display a meal event entry screen that includes a meal type selectable element for specifying a type of meal. The meal type selectable element may be initially set to the selected default meal type, and the meal type selectable element may be capable of being set to a different one of the plurality of meal types. The display device may enable a user to adjust default time intervals for selecting the default meal type, and the display device may display an event log screen that includes an add event selectable element for adding one or more events including one or more meal events based on the adjusted default time intervals.

Abstract: A detection system may include a moveable tray configured to hold a multi-cell container of one or more reagents and/or one or more samples. A driving mechanism may be configured to reciprocate the tray in the first linear direction to agitate contents of the container, and may be configured to conduct electrochemiluminescence or other measurements on samples located in the container. The system may include an apparatus for retaining a container, a device for detecting the presence of a container, an apparatus for training a probe to locate and aspirate one or more reagents and/or one or more samples, a latching mechanism for moving parts in the system, and/or a positive displacement pump. A controller may be configured to control linear reciprocation of the tray to have one of a piecewise constant velocity profile and piecewise constant acceleration profile in which the number of piecewise constants does not exceed 24.
