Abstract
A system utilizing time tracking is disclosed. The system includes a real time clock, a time component, and a controller. The real time clock is configured to track time. The time component is configured to measure a time value without an additional power source. The controller is configured to determine an elapsed time using the time value and calibration information and to update the real time clock using the elapsed time in a restart mode.
Claims20
A system utilizing time tracking, the system comprising:
- a real time clock configured to track time in an ON mode and deactivate in an OFF mode;
- a time component configured to track a time value during the OFF mode;
- and
- a controller configured to determine the elapsed time using the tracked time value and to update the real time clock using the elapsed time in a restart mode prior to the real time clock transitioning to the ON mode.
A system utilizing time tracking, the system comprising:
- a removable battery power source configured to generate a main supply;
- a real time clock configured to utilize the main supply to track time, wherein the real time clock uses an elapsed time to generate a current time in a restart mode;
- and
- a time component configured to track the elapsed time on removal of the battery power source from the real time clock in an OFF mode, wherein the time component is self powered.
A method of operating a system having time tracking, the method comprising:
- tracking time with a real time clock in an ON mode;
- developing calibration information in a calibration mode;
- using a time component to track a time value in an OFF mode;
- and
- developing an elapsed time of the OFF mode using the calibration information and the time value.
