Abstract

A method for the dynamically determining utilization of remote device applications based on historical application usage patterns, application power requirements, and available power reserves stored on a remote device, wherein the method includes defining a set of individual applications and activities on a remote device; determining a rate of power consumption per unit of time for each of the set of individual applications and activities; determining usage patterns of the set of individual applications and activities; determining a total expected power usage; comparing the total expected power usage to the available power reserves; and implementing a power budget if the total expected power usage exceeds the available power reserves.

Claims

1. A method for dynamically determining utilization of remote device applications based on historical application usage patterns, application power requirements, and available power reserves stored on a remote device, wherein the method comprises:

defining a set of individual applications and activities on a remote device;

determining a rate of power consumption per unit of time for each of the set of individual applications and activities;

determining usage patterns of the set of individual applications and activities;

determining a total expected power usage;

comparing the total expected power usage to the available power reserves; and

implementing a power budget whenever the total expected power usage exceeds the available power reserves.

2. The method of claim 1, wherein implementing a power budget comprises:

determining the required operating time of the remote device;

determining user defined power saving measures;

implementing power saving measures initiated by the remote device.

3. The method of claim 2, wherein:

determining the required operating time of the remote device is based on the user determining the period between recharging the remote device.

4. The method of claim 2, wherein:

determining the required operating time of the remote device is based on the remote device determining the period between recharging based on its operational history.

5. The method of claim 2, wherein determining user defined power saving measures comprises:

the user setting priorities and limits on the remote device'"'"'s applications.

6. The method of claim 2, wherein implementing power saving measures initiated by the remote device comprises:

the remote device setting priorities and limits on the remote device'"'"'s applications.

7. The method of claim 2, wherein implementing power saving measures initiated by the remote device comprises:

the remote device providing usage feedback to the user, wherein the usage feedback further comprises;

altering ring tones to indicate incoming calls that should be kept short in duration;

recommending incoming and outgoing call durations based on a user determined priority list; and

altering notifications and providing user alerts.

8. The method of claim 2, wherein implementing power saving measures initiated by the remote device comprises:

canceling or deferring scheduled applications within constraints provided by the user.

9. The method of claim 2, wherein implementing power saving measures initiated by the remote device comprises:

adjusting the remote device'"'"'s display screen brightness and resolution.

10. The method of claim 2, wherein:

implementing a power budget is facilitated by a user interface that provides graphics illustrating application usage, application power consumption, and estimates of time of available charge based on historical usage patterns.

11. An article comprising machine-readable storage media containing instructions that when executed by a processor enable the processor to perform a dynamic determination for the utilization of remote device applications based on historical application usage patterns, application power requirements, and available power reserves stored on a remote device, wherein the remote device comprises:

laptop computers, mobile computing devices, mobile communication devices, and personal digital assistants (PDA);

wherein the instructions comprise algorithms for implementing a power budget; and

wherein the algorithm further comprises;

defining a set of individual applications and activities on a remote device;

determining a rate of power consumption per unit of time for each of the set of individual applications and activities;

determining usage patterns of the set of individual applications and activities;

determining a total expected power usage;

comparing the total expected power usage to the available power reserves; and

implementing the power budget whenever the total expected power usage exceeds the available power reserves.

12. The article of claim 11 wherein implementing the power budget comprises:

determining the required operating time of the remote device;

determining user defined power saving measures;

implementing power saving measures initiated by the remote device.

13. The article of claim 12 wherein determining the required operating time of the remote device is based on a user determining the period between recharging the remote device.

14. The article of claim 12 wherein determining the required operating time of the remote device is based on the remote device determining the period between recharging based on its operational history.

15. The article of claim 12 wherein determining the required operating time of the remote device is based on the remote device determining the period between recharging based on its operational history.

16. The article of claim 12 wherein determining user defined power saving measures comprises:

a user setting priorities and limits on the remote device'"'"'s applications.

17. The article of claim 12 wherein implementing power saving measures initiated by the remote device comprises:

the remote device setting priorities and limits on the remote device'"'"'s applications;

canceling or deferring scheduled applications within constraints provided by the user;

adjusting the remote device'"'"'s display screen brightness and resolution; and

the remote device providing usage feedback to the user, wherein the usage feedback further comprises;

altering ring tones to indicate incoming calls that should be kept short in duration;

recommending incoming and outgoing call durations based on a user determined priority list;

altering notifications and providing user alerts;

18. The article of claim 12 wherein implementing a power budget is facilitated by a user interface that provides graphics illustrating application usage, application power consumption, and estimates of time of available charge based on historical usage patterns.

19. The article of claim 18 wherein the user interface recommends interim minimal remote device charging times that provide adequate operating power for required user remote device usage intervals between full device charges.

20. The article of claim 18 wherein the user interface provides prompts and user advisories when remote device charging is required, as well as alerts when imminent remote device shut down will occur.
