Patents by Inventor Calin N. Bugnariu

Calin N. Bugnariu has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • System and method of battery capacity estimation
    Patent number: 8655613
    Abstract: A method includes measuring an operating parameter of a battery of a mobile device. The measured operating parameter is translated into an equivalent series resistance (ESR) value. The ESR value is adjusted by a correction factor to generate a corrected ESR value. The capacity of the battery is determined based on the corrected ESR value. The correction factor is automatically calibrated based on the measured operating parameter.
    Type: Grant

  • System and method of battery capacity estimation
    Patent number: 7983863
    Abstract: In accordance with the teachings described herein, systems and methods are provided for battery capacity estimation. A profile table may be used that relates a plurality of battery profile values with a plurality of operating parameter values. The profile table may be accessed to translate one or more measured operating parameters into one or more corresponding battery profile values. One or more of the battery profile values may be adjusted by a correction factor to generate a corrected battery profile value. The available capacity of the battery may be calculated using the corrected battery profile value. The correction factor may then be automatically calibrated by using an estimated battery profile value calculated from the one or more measured operating parameter.
