Definitions
- This invention relates to products with inbuilt batteries, which may inadvertently be left powered on.
- the invention relates to mobile communication devices such as mobile phones, which could be left powered on with no SIM card inserted.
- the invention is also applicable to other devices which may inadvertently be left powered on.
- a mobile communications device could inadvertently be left powered on, for example, when a mobile phone with a built in battery is manufactured, and is shipped from the factory without a SIM card, but could accidentally be switched on, or could inadvertently be left switched on after testing or other procedures in the factory.
- the device is provided with software or hardware which detects that the power is connected to the product.
- the software or hardware detects that the SIM card is not inserted in the device. If the SIM card is not inserted, the software or hardware starts a timer. After the expiry of a preset time period, the software or hardware will check to confirm whether the relevant emergency call digits (e.g. 112, 999, 911, etc) or any other digits have been dialled, or if an emergency call is in progress .
- relevant emergency call digits e.g. 112, 999, 911, etc
- the software or hardware will automatically remove power from the product and power down in the normal manner.
- the invention is generally applicable to portable radio communication equipment or mobile radio terminals, such as mobile telephones, pagers, communicators, electronic organisers, smartphones, personal digital assistants (PDAs), or the like.
- portable radio communication equipment or mobile radio terminals such as mobile telephones, pagers, communicators, electronic organisers, smartphones, personal digital assistants (PDAs), or the like.

- FIG. 1 is a block schematic diagram of a mobile communications device in accordance with an aspect of the invention.
- FIG. 2 is a flowchart illustrating a process in accordance with another aspect of the invention.
- FIG. 1 shows a mobile communications device, specifically a mobile phone 200.
- the phone 200 may be generally conventional, except as described herein, with only those features which are essential for an understanding of the invention being described.
- the phone 200 includes a built in battery 210, which provides power for the phone .
- the phone includes a controller 215, which receives user inputs from a keypad 220, for example, and also includes radio frequency transceiver circuitry 230, which receives and transmits signals via an antenna 240.
- the controller 215 is also connected to any SIM card, which may be present in a SIM card holder 250.
- the controller is also able to start a timer, and judge the expiry of a specified time period from the start of the timer.
- control process according to the invention is carried out in software within the controller 215.
- at least some aspects of the process could be carried out in hardware, under the general control of the controller 215.
- FIG. 2 is a flowchart illustrating a control process in accordance with the present invention.
- step 5 the power to the mobile communications device is switched on.
- the process proceeds to step 10 where the power is detected.
- step 15 a check is carried out to determine the presence of a SIM card. If a SIM card is found to be present then the process passes to step 20, where the validity of the SIM card is checked. If the SIM card has not expired, then the process goes to step 100 and ends .
- step 15 determines there is no SIM card present, or the test at step 20 determines that any SIM card which is present has expired, then the process moves to step 25 where a timer is started.
- step 30 it is tested whether any key on the keypad of the device has been pressed. If a digit has been dialled, then the process moves to step 40 where the timer is restarted. If no digits have been dialled, then the process moves to step 35 where the status of a call is checked.
- step 40 In the event that a call is found to be in progress, the process moves to step 40 and the timer is restarted. If it is found that no calls are in progress then the process moves to step 45 where the elapsed time is checked. If a preset time X has not yet elapsed, then the process returns to step 30. If a preset time X has elapsed, then the process moves to step 50 and the power is disconnected from the mobile communications device. The process then ends at step 100.
- the power is automatically switched off. This occurs after a time period X, which is preferably set to be several minutes, preferably 10 minutes or more. In one preferred embodiment, the time period is 30 minutes. After the power is automatically switched off, it remains possible to repower the device in the normal way.
- the invention is described herein with reference to a control procedure in which the power is disconnected in the event that the power is switched on when no SIM card is present.
- the invention also relates to a control procedure in which the power is switched off (after the preset time period) if the SIM card is removed while the power source, is connected.
- These procedures both have the advantage that a device with an internal battery can not be left on without a SIM card inserted. This prevents transmissions that may interfere with other systems, or battery drain.
- the problem solved by the present invention namely that the mobile communication device could inadvertently be left powered on and could then emit transmissions which could interfere with other communication systems or could drain the power source, can also arise in other situations. If it can be determined in other ways that the device has been left powered on inadvertently, then the device can also automatically be powered down in such situations.
