Classification: CPC A | IPC A

Claim 13:
14. A method comprising:
generating a physiological signal by a sensor coupled to a power source;
detecting events from the physiological signal;
delivering electrical stimulation pulses based on at least the events detected from the physiological signal;
determining a voltage of the power source;
determining a first current drain including electrical current required from the power source for at least one of: generating the physiological signal and detecting the events from the physiological signal;
determining that the determined voltage of the power source has reached a first voltage;
starting a timer to track an elapsed time in response to determining that the determined voltage of the power source has reached the first voltage;
determining an estimated time from a first voltage of the power source until a second voltage of the power source based on the first current drain and a power source capacity difference, where the first voltage of the power source corresponds to a first power source capacity, the second voltage corresponds to a second power source capacity less than the first power source capacity, and the power source capacity difference is the difference between the first power source capacity and the second power source capacity;
determining a value of the timer when the estimated time is determined;
adjusting the estimated time by the value of the timer; and
generating an output based on the adjusted estimated time; and
storing in memory data corresponding to the adjusted estimated time in response to the generated output.
