  • Apparatus and method for battery passivation compensation in a medical device
    Patent number: 11532826
    Abstract: A method for operating a medical device includes activating a processor in the medical device in a low-power operating mode, measuring a first voltage level of the battery, applying at least one discharge pulse to the battery in response to the first voltage level of the battery being greater than a predetermined passivation minimum voltage threshold and less than a predetermined passivation maximum voltage threshold, measuring a second voltage level of the battery after the at least one discharge pulse, and operating the processor in the medical device in an increased-power operating mode to continue operation of the medical device only in response to the second voltage level being greater than or equal to a predetermined operating voltage threshold, the predetermined operating voltage threshold being greater than the predetermined passivation minimum voltage threshold and less than or equal to the predetermined passivation maximum voltage threshold.
    Type: Grant

    Date of Patent: December 20, 2022
    Assignee: Roche Diabetes Care, Inc.
    Inventors: Larry Lewis Lockridge, Duane Patrick Fridley, Kurt Gerard Klem, Michael Joseph Blackburn, Nathan Eugene Manlove, Steven Kent Moore, Marshall M. Parker
