This application is the National Stage under Section 371 of International Patent Application PCT/GB2013/050796 filed on Mar. 27, 2013, which application claims the benefits of priority of prior filed U.S. Provisional Patent Application Ser. No. 61/618,601 filed on Mar. 30, 2012, which prior applications are hereby incorporated by reference as if fully set forth herein.
Referring back to step 206, where the process has determined that the battery level is greater than the first threshold, the system moves to step 214 to perform a start-up check process for the system. After the system start up check, a battery status change is detected by way of query 216 in which both the battery level and the low battery flag are evaluated together. Specifically, the logic determines in step 216 whether both the battery level is above a second threshold and the low battery flag is turned on. If step 216 returns a true or affirmative then this means that a new battery has been inserted due to the battery level being greater than the second threshold, which is higher than the first threshold. Because the battery low flag has been set, the inference here is that a fresh new battery has been inserted or in the case of rechargeable battery, the battery was fully recharged. Consequently, the logic moves to step 218 to record the battery condition status (e.g., date, time, voltage level, amperage level, electrostatic events, or any other parameters) in a section of the memory separate from the measurement data. Optionally, the system may annunciate this change to the user in step 220. Thereafter, the low battery flag is turned off. The logic then moves back to step 224 for the processor to proceed with the physiological measurement. At step 226, the system checks the battery level to see if the level is greater than the first threshold. If the check or query at step 228 returns a true or affirmative then the system can proceed to annunciating the result of the measurement test at step 230 and the result, along with the battery level (e.g., voltage or power) and other data are stored in the measurement test record memory. On the other hand, if the check at step 228 returns a false or negative (i.e., the battery level is below the first threshold), the system moves to step 208 to annunciate a low battery warning along with setting the low battery level flag on and terminating the process in step 212 to conserve any battery level that remains. As used herein, the term “annunciated” and variations on its root term indicate that an announcement may be provided via text, audio, visual or a combination of all modes or mediums of communication to a user.
