Abstract

Methods and systems are provided for indicating battery information to cellular telephone users when a cellular telephone is near an associated battery charger. When a cellular telephone is within a predetermined range of the battery charger, the charger and telephone form a communication link The link allows the charger (or telephone) to analyze the status of the telephone'"'"'s battery, generate alert commands and/or generate sensory alerts as needed in order to warn a user to charge the battery. The charger can also be adapted to establish a communication link with a personal computer (“PC”) and to transmit similar commands to the personal computer via the link to allow the PC to generate sensory alerts.

Claims

1. A cellular telephone system comprising:

a battery charger adapted to generate an alert command when a cellular telephone is located within a predetermined range of the charger.

2. The system of claim 1, wherein the battery charger is further adapted to generate a sensory alert responsive to the alert command.

3. The system of claim 1, further comprising a cellular telephone adapted to generate a sensory alert responsive to the alert command.

4. The system of claim 1 further comprising a personal computer adapted to generate a sensory alert responsive to the alert command.

5. The system of claim 1 wherein the range is substantially 10 meters.

6. A cellular telephone system comprising:

a cellular telephone adapted to generate an alert command when the telephone is located within a predetermined range of a battery charger.

7. The system of claim 6, wherein the cellular telephone is adapted to generate a sensory alert responsive to the alert command.

8. The system of claim 6, further comprising a battery charger adapted to generate a sensory alert responsive to the alert command.

9. The system of claim 6, further comprising a personal computer adapted to generate a sensory alert responsive to the alert command.

10. The system of claim 6 wherein the range is substantially 10 meters.

11. A battery charger adapted to generate a sensory alert responsive to an alert command when a cellular telephone is located within a predetermined range of the charger.

12. The charger of claim 11 wherein the range is substantially 10 meters.

14. The telephone of claim 13 wherein the range is substantially 10 meters.

16. The personal computer of claim 15 wherein the range is substantially 10 meters.

18. The device of claim 17, wherein the device is further adapted to control the generation of a sensory alert responsive to the alert command.

19. The programmed device of claim 17 wherein the range is substantially 10 meters.

13. A cellular telephone adapted to generate a sensory alert responsive to an alert command when the telephone is located within a predetermined range of a battery charger.

15. A personal computer adapted to generate a sensory alert responsive to an alert command when a cellular telephone is located within a predetermined range of a battery charger.

17. A programmed device adapted to control the generation of an alert command when a cellular telephone is located within a predetermined range of a battery charger.

20. A programmed device adapted to control the generation of a sensory alert responsive to an alert command when a cellular telephone is located within a predetermined range of a battery charger.

21. The programmed device of claim 20 wherein the range is substantially 10 meters.

22. A method for indicating cellular telephone battery-charging information comprising:

generating an alert command when a cellular telephone is located within a predetermined range of a battery charger.

23. The method of claim 22, further comprising generating a sensory alert responsive to the alert command.

24. The method of claim 22 wherein the range is substantially 10 meters.

26. The method of claim 25 wherein the range is substantially 10 meters.

25. A method for indicating cellular telephone battery-charging information comprising:

generating a sensory alert responsive to an alert command when a cellular telephone is located within a predetermined range of a battery charger.
