Abstract
Some embodiments of an infusion pump system can employ a number of power management techniques to avoid using substantially excessive power during operation of the pump drive system. Thus, the infusion pump system can draw upon the energy supply in an efficient manner that extends the useful life on the power supply. Furthermore, the infusion pump system can be configured estimate an amount of power remaining to operate the pump system without the requirement of directly detecting the remaining charge on power supply device (e.g., without detecting the remaining charge on a battery). As such, the infusion pump system can readily inform a user of a particular estimated amount of time remaining for medicine dispensing operations.

2. A wearable infusion pump system, comprising:
-
a pump device including a drive system to dispense medicine from the pump device; an energy storage source to deliver electrical energy to the drive system to initiate actuations of the drive system to perform a medicine dispensing operation; and a controller device to initiate the medicine dispensing operation by supplying energy to the drive system, the controller detecting an actuation time, period, or frequency for one or more actuations and adjusting the supplied energy for one or more subsequent actuations of the drive system based on the actuation time, period, or frequency. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12)

13. A method of administering medicinal fluid to a patient, the method comprising:
-
initiating, by one or more controllers of a wearable infusion pump system, one or more actuations of a drive system of a pump device of the wearable infusion pump system;
the drive system configured to dispense medicine from the pump device;detecting, by the one or more controllers, an actuation time, period, or frequency for the one or more actuations of the drive system; adjusting, by the one or more controllers, electrical energy supplied for one or more subsequent actuations of the drive system based on the detected actuation time, period, or frequency. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)
