Abstract

An apparatus for providing a boot-up capability signal for a portable electronic device, the apparatus configured to determine an amount of charge provided to a battery of the device by a charging process, based around one or more powering events, in order to provide for the boot-up capability signal.

Claims

1. An apparatus for providing a boot-up capability signal for a portable electronic device, the apparatus configured to determine an amount of charge provided to a battery of the device by a charging process, based around one or more powering events, in order to provide for the boot-up capability signal.

2. An apparatus according to claim 1, wherein the apparatus is configured to determine the amount of charge provided to the battery from a charging initiation powering event.

3. An apparatus according to claim 1, wherein the apparatus is configured to determine the amount of charge provided to the battery from a boot-up powering event.

4. An apparatus according to claim 1, wherein the apparatus is configured to determine the level of current provided to the battery over a particular period of time associated with the powering event to determine the amount of charge provided to the battery.

5. An apparatus according to claim 1 wherein the apparatus is configured to determine the level of current provided to the battery over a particular period of time associated with the powering event to determine the amount of charge provided to the battery, and wherein the apparatus is additionally configured to determine the corresponding level of voltage supplied to the battery to determine the power supplied to the battery, such that the amount of energy provided to the battery over the particular period of time associated with the powering event can be determined.

6. An apparatus according to claim 1, wherein the apparatus is configured to determine at least one instantaneous current level provided to the battery, based around the powering event, and integrate this instantaneous current over at least one non-measured particular period of time, to determine the amount of charge provided to a battery.

7. An apparatus according to claim 1, wherein the apparatus is configured to additionally determine the corresponding battery voltage to provide for the boot-up capability signal.

8. An apparatus according to claim 1, wherein the apparatus is configured to use the boot-up capability signal and a criterion to provide for control of boot-up of the portable electronic device.

9. An apparatus according to claim 8, wherein the apparatus is configured to determine a temperature to provide for the boot-up capability signal/criterion.

10. An apparatus according to claim 9, where the apparatus is configured to determine one of the ambient temperature, and the battery temperature, to provide for the boot-up capability signal/criterion.

11. An apparatus according to claim 1, comprising circuitry configured to measure the level of current provided to the battery over a measured particular period of time associated with the powering event to determine the amount of charge provided to the battery.

12. An apparatus according to claim 11, wherein the circuitry comprises a measurer to determine the amount of charge, to provide for the boot-up capability signal.

13. An apparatus according to claim 11, wherein the circuitry comprises a controller configured to receive the boot-up capability signal and use with a particular criterion to provide for control of boot-up of the portable electronic device.

14. An apparatus according to claim 11, wherein the circuitry comprises a processor to determine the amount of charge to provide for the boot-up capability signal and to provide for control of boot-up of the portable electronic device.

15. An apparatus according to claim 11, wherein the circuitry is further configured to determine the battery voltage and a temperature to provide for the boot-up capability signal.

16. An apparatus according to claim 15, wherein the circuitry is configured to determine one of the ambient temperature, and the battery temperature, to provide for the boot-up capability signal.

17. An apparatus according to claim 11, wherein the circuitry is further configured to determine the battery voltage to provide for the boot-up capability signal.

18. An apparatus according to claim 1, wherein the apparatus is a module for a portable electronic device.

19. An apparatus according to claim 13, wherein the apparatus further comprises a processor, configured to receive power from the battery, and to receive a control boot up signal from the controller, so as to provide for boot-up of a portable electronic device.

20. An apparatus according to claim 19, wherein the controller is configured to delay boot-up of the portable electronic device, until receipt of an affirmative boot-up capability signal.

21. An apparatus according to claim 19, wherein the controller is configured to delay boot-up of the portable electronic device, until a received boot-up capability signal satisfies a predetermined criterion.

22. A portable electronic device comprising the apparatus according to claim 1.

23. A portable electronic device according to claim 22, wherein the device is one of:

a mobile phone;

Personal Digital Assistant;
