POWER SUPPLIES MANAGEMENT IN AN ANALYTE DEVICE HAVING PRIMARY AND SECONDARY BATTERIES
First Claim
1. A method of managing power supplies in an analyte measurement device having a microprocessor coupled to a memory, the device including a primary battery and a secondary battery with the primary battery coupled to the microprocessor to power the microprocessor, the method comprising the steps of:
- evaluating with the microprocessor whether a measured capacity of the primary battery is greater than a first threshold;
in the event the evaluating step returns an indication that the measured capacity of the primary battery is less than the first threshold, ascertaining whether a capacity of the primary battery is greater than a second threshold;
in the event the ascertaining step returns an indication that the measured capacity of the primary is less than the second threshold, querying whether a measured capacity of the secondary battery is greater than the second threshold; and
in the event the ascertaining step returns an indication that the measured capacity of the secondary battery is greater than the second threshold, then connecting the secondary battery to the microprocessor to power the microprocessor.

Abstract
Described herein are systems and methods (including system and method) to allow users of analyte monitors to continue to perform analyte measurement tests by using a secondary battery when the main battery is exhausted. By using applicants'"'"' technique, the monitor can be used for twice as long as compared to a monitor that only relies on a single battery as the only power supply. Moreover, applicants have devised systems and methods to indicate to the user which of the primary and secondary batteries should be replaced without disrupting the utilization of the monitor.

11. An analyte measurement system comprising:
-
a biosensor unit that receives a physiological fluid of a use to allow for determination of an analyte in the fluid; and a portable physiological monitor unit comprising; a microprocessor in communication with the biosensor unit to receive a plurality of analyte measurements reflective of a health condition of the user, the microprocessor being coupled to a memory and at least one of a primary and secondary batteries;
the microprocessor being configured to;measure a capacity of the primary battery and if the measured capacity is less than a first threshold then evaluate a capacity of the primary battery with respect to a second threshold; annunciate a low battery condition if there is an indication that the measured capacity of the primary battery is greater than or equal to the second threshold; evaluate the capacity of the secondary battery with respect to the secondary threshold and if there is an indication that the measured capacity of the primary is less than the second threshold then prevent usage of the unit otherwise if there is an indication that the measured capacity of the secondary battery is greater than the second threshold then the secondary battery is connected to the microprocessor to power the microprocessor; measure a capacity of the secondary battery; determine whether a measured capacity of the secondary battery is greater than a third threshold; prevent a connection of the backlight to the secondary battery if there is an indication that the measured capacity of the secondary battery is less than the third threshold; evaluate whether the measured capacity of the secondary battery is greater than a fourth threshold if there is an indication that the measured capacity of the secondary battery is greater than the third threshold; and annunciate that the capacity of the secondary battery is low if there is an indication that the measured capacity of the secondary battery is less than the fourth threshold. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
