Abstract

A battery-powered device comprising: a memory storing software essential to the provision of normal functions of the device; a first processing section (16) comprising a data processor capable of executing the software, the device being capable of operating the first processing section in a normal mode in which it can execute the software and a low power mode; a second processing section (5) having a clock (6) for maintaining a time, and being capable of triggering behaviour of the device in response to the time of the clock preceding a user-set time by a pre-set advance interval; the device being configured to, in response to triggering by the second processing section when the first processing section is in the low power mode, cause the first processing section to enter the normal mode and to load the software.

Claims

1. A battery-powered device comprising:

a memory storing software essential to the provision of normal functions of the device;

a first processing section comprising a data processor capable of executing the software, the device being capable of operating the first processing section in a normal mode in which it can execute the software and a low power mode;

a second processing section having a clock for maintaining a time, and being capable of triggering behaviour of the device in response to the time of the clock preceding a user-set time by a pre-set advance interval;

the device being configured to, in response to triggering by the second processing section when the first processing section is in the low power mode, cause the first processing section to enter the normal mode and to load the software

2. A device as claimed in claim 1, wherein the pre-set advance interval is such as to allow the software to be loaded prior to the user-set time.

3. A device as claimed in claim 1, wherein the software is at least part of an operating system of the device.

4. A device as claimed in any preceding claim 1, wherein the first processing section comprises a data processor and a volatile memory for storing software when it has been loaded.

5. A device as claimed in claim 4, wherein in the low power mode the processor receives insufficient power to operate normally.

6. A device as claimed in claim 4, wherein in the low power mode the volatile memory receives insufficient power to store software.

7. A device as claimed in any preceding claim 1, wherein the device is a portable device.

8. A device as claimed in any preceding claim 1, comprising a communication interface for downloading data and a data store for storing a list of one or more user-set data locations, and wherein the device is configured to, in response to triggering by the second processing section download data from the or each user-set data location via the communication interface.

9. A device as claimed in claim 8, wherein the pre-set advance interval is such as to allow the data to be downloaded prior to the user-set time.

10. A device as claimed in claim 8, wherein the communication interface is capable of receiving the data by a wireless data link thereto.

11. A device as claimed in claim 10, wherein the communication interface is capable of receiving the data by radio.

12. A device as claimed in claim 11, wherein the device is a mobile phone and the communication interface is capable of communication with a mobile phone network for downloading the data.

13. A device as claimed in claim 8, comprising a memory for storing the downloaded data.

14. A device as claimed in claim 1, comprising a user interface for presenting the downloaded data to a user.

15. A method for operating a device comprising a memory storing software essential to the provision of normal functions of the device, a first processing section comprising a data processor capable of executing the software, the device being capable of operating the first processing section in a normal mode in which it can execute the software and a low power mode;

and a second processing section having a clock for maintaining a time, and being capable of triggering behaviour of the device in response to the time of the clock preceding a user-set time by a pre-set advance interval;

the method comprising;

in response to triggering by the second processing section when the first processing section is in the low power mode, causing the first processing section to enter the normal mode and to load the software.
