1. A method of monitoring power in a portable physiological measurement device that has at least a battery coupled to a processor and memory, the method comprising the step of:
- turning on the device;
measuring with the microprocessor power of the battery;
determining if the power level of the battery is greater than a first threshold;
if the power level is less than or equal to the first threshold then setting a flag for low battery as true otherwise performing start up checking process of the device;
after the performing of the startup checking process, evaluating the battery to determine if both the power level of the battery is greater than a second threshold and the low battery flag is set as true;
if the evaluating step is affirmative then recording the time and date of the evaluating step to memory and setting the flag for low battery as false and annunciating a status of the battery in the device;
if the evaluating step is negative, then conducting an analyte measurement;
checking the power level of the battery against the first threshold;
if the checking indicates that power level is greater than the first threshold then annunciating a result of the physiological measurement otherwise ending the checking step.

Abstract
Described herein are systems and methods to determine when a new or fresh battery has been replaced in a medical monitoring device and store a record of such battery replacement so that the battery records of the medical monitoring device can be reliably kept over the life of the monitoring device.

10. A physiological measurement system comprising:
-
a biosensor unit that provides physiological data of a user; and a portable disease management unit comprising; a microprocessor in communication with the biosensor unit to receive a plurality of physiological measurements reflective of a health condition of the user, the microprocessor being coupled to a memory and a battery;
the microprocessor being configured to;set a low battery flag as true when a power level of the battery is lower than a first threshold; evaluate whether both a power level of the battery is greater than a second threshold and the low battery flag is true; store in the memory a time and date when an evaluation is affirmative for both the power level of the battery is greater than a second threshold and the low battery flag is true; set the low battery flag as false when the time and date of the evaluation is stored in memory; and annunciate that a status of the battery has changed at the time and date stored in memory. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A method of monitoring battery power in a portable electronic medical device that has at least a battery coupled to a processor and memory, the method comprising the steps of:
-
measuring a power level of the battery; determining if the power level of the battery is greater than a first threshold; if the power level is less than or equal to the first threshold then setting a flag for low battery as true otherwise performing other process step for the device; after the performing of other process step, evaluating the battery to determine if both the power level of the battery is greater than a second threshold and the low battery flag is set as true; if the evaluating step is affirmative then recording the time and date of the evaluating step to memory and setting the flag for low battery as false; and annunciating a change in status of the battery in the device. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)
