Simulated resolution of stopwatch
View Patent ↗There is described a mobile device comprising a display screen for displaying an image of a clock having a resolution of at least a first digit representing a tenth of a second and a second digit representing a hundredth of a second; and a processor having an internal clock, the processor adapted to update at least the first digit of the image of the clock on the display screen with true elapsed time, and to update the second digit with a non-true number.
1. A computer-implemented method for providing a stopwatch feature on a mobile device comprising:
displaying an image of a digital clock on a display screen of the mobile device, the digital clock having a resolution of at least a first digit followed by at least a second digit;
receiving an activation trigger to begin the clock;
determining true elapsed time up to and including the at least second digit;
removing a true number representing the at least second digit from the true elapsed time and replacing it with a non-true number; and
updating the display screen with the true elapsed time up to and including the first digit, and the non-true number for the at least second digit.
2. The method of claim 1 , further comprising:
repeating the steps of determining true elapsed time, removing the true number, replacing with a non-true number, and updating the display screen until a deactivation trigger to stop the clock is received; and
displaying a fixed image of the clock on the display screen in accordance with a most recent update of the true elapsed time.
3. The method of claim 1 , wherein the first digit represents a tenth of a second and the second digit represents a hundredth of a second.
4. The method of claim 1 , wherein the non-true number is a pseudo-random number incremented by 3 at every update iteration.
5. The method of claim 1 , wherein the non-true number is a randomly generated number.
6. The method of claim 2 , wherein the displaying a fixed image comprises updating the display screen once more with the true elapsed time to the second digit.
7. The method of claim 3 , wherein updating the display screen is done at a rate of every tenth of a second.
8. The method of claim 1 , wherein determining true elapsed time comprises:
accessing an internal clock of the mobile device;
subtracting a last recorded time since a previous update, and
obtaining the true elapsed time.
9. A mobile device comprising:
a processor coupled to a memory and a display screen and adapted to run software for:
displaying an image of a digital clock on a display screen of the mobile device, the digital clock having a resolution of at least a first digit followed by at least a second digit;
receiving an activation trigger to begin the clock;
determining true elapsed time up to and including the at least second digit;
removing a true number representing the at least second digit from the true elapsed time and replacing it with a non-true number; and
updating the display screen with the true elapsed time up to and including the first digit, and the non-true number for the at least second digit.
10. The mobile device of claim 9 , wherein the software is further adapted for:
repeating the steps of determining true elapsed time, removing the true number, replacing with a non-true number, and updating the display screen until a deactivation trigger to stop the clock is received; and
displaying a fixed image of the clock on the display screen in accordance with a most recent update of the true elapsed time.
11. The mobile device of claim 9 , wherein the first digit represents a tenth of a second and the second digit represents a hundredth of a second.
12. The mobile device of claim 9 , wherein the software is adapted to increment the non-true number by 3 at every update iteration.
13. The mobile device of claim 9 , wherein the non-true number is randomly generated for every update iteration.
14. The mobile device of claim 10 , wherein the displaying a fixed image comprises updating the display screen once more with the true elapsed time for the second digit.
15. The mobile device of claim 9 , wherein updating the display screen is done at a rate of every tenth of a second.
16. The mobile device of claim 9 , wherein determining true elapsed time comprises:
accessing an internal clock of the mobile device;
subtracting a last recorded time since a previous update, and
obtaining the true elapsed time.
17. A mobile device comprising:
a display screen for displaying an image of a clock having a resolution of at least a first digit representing a tenth of a second and a second digit representing a hundredth of a second; and
a processor having an internal clock, the processor adapted to run software to update at least the first digit of the image of the clock on the display screen with true elapsed time, and to update the second digit with a non-true number.
18. The mobile device of claim 17 , wherein the software is adapted to increment the non-true number by 3 at every update iteration.
19. The mobile device of claim 17 , wherein the software is adapted to, after having received a deactivation trigger, update the display screen once more with the true elapsed time to the hundredth of a second.
20. The mobile device of claim 17 , wherein updating the display screen is done at a rate of every tenth of a second.
