Smoking substitute device

1. A smoking substitute device, comprising:

a control unit; and

an accelerometer, configured to detect an orientation of the smoking substitute device and provide data indicative of the detected orientation to the control unit;

wherein the control unit is configured to trigger an alert when it determines from the data indicative of the detected orientation that the smoking substitute device will function improperly; and

wherein the control unit is configured to determine from the data indicative of the detected orientation that the smoking substitute device will function improperly when the data indicative of the detected orientation indicates that a gravity fed heating device of the smoking substitute device has been located above a tank containing a vaporizable liquid for a predetermined period of time, wherein the predetermined period of time is at least 30 minutes.

2. The smoking substitute device of claim 1 , wherein the control unit is configured to determine whether the smoking substitute device is held in an inappropriate orientation whilst the heating device is being used, and to trigger the alert immediately when it is determined that the smoking substitute device is held in an inappropriate orientation whilst the heating device is being used.

3. The smoking substitute device of claim 1 , wherein triggering the alert includes disabling the smoking substitute device.

4. The smoking substitute device of claim 3 , wherein the predetermined period of time is a first predetermined period of time, wherein the control unit is configured to re-enable the smoking substitute device when it is determined, via the data indicative of the detected orientation, that the smoking substitute device has been held in an appropriate orientation for a second predetermined period of time.

5. The smoking substitute device of claim 4 , wherein the second predetermined period of time is at least 1 second.

6. The smoking substitute device of claim 1 , wherein the control unit is configured to re-enable the smoking substitute device when it receives a re-enablement signal from a remote device via a wireless interface of the smoking substitute device.

7. The smoking substitute device of claim 4 , wherein the appropriate orientation is one in which a gravity fed heating device of the smoking substitute device is located below a tank containing a vaporizable liquid.

8. The smoking substitute device of claim 1 , wherein triggering the alert includes sending a message via a wireless interface to a remote device indicating that the smoking substitute device will function improperly.

9. The smoking substitute device of claim 1 , wherein triggering the alert further includes activating an indicator light on the smoking substitute device.

10. The smoking substitute device of claim 1 , wherein the control unit is configured to determine from the data indicative of the detected orientation that the smoking substitute device will function improperly when the data indicative of the detected orientation indicates that a wick of the smoking substitute device is not saturated with a vaporizable liquid.

11. A system comprising a smoking substitute device and remote device, wherein the smoking substitute device comprises:

a control unit;

an accelerometer configured to detect an orientation of the smoking substitute device and provide data indicative of the detected orientation to the control unit; and

a wireless interface; and

wherein the control unit is configured to provide the data indicative of the detected orientation to the remote device via the wireless interface;

wherein the remote device or control unit is configured to trigger an alert when the remote device or control unit determines from the data indicative of the detected orientation that the smoking substitute device will function improperly; and

wherein the remote device or control unit is configured to determine from the data indicative of the detected orientation that the smoking substitute device will function improperly when the data indicative of the detected orientation indicates that a gravity fed heating device of the smoking substitute device has been located above a tank containing a vapourisable liquid for a predetermined period of time, wherein the predetermined period of time is at least 30 minutes.

12. The system of claim 11 , wherein triggering the alert includes disabling the smoking substitute device.

13. The system of claim 12 , wherein the control unit is configured to re-enable the smoking substitute device when it is determined, via data received from the accelerometer, that the smoking substitute device has been held in an appropriate orientation for a first predetermined period of time.

14. The system of claim 13 , wherein the appropriate orientation is one in which a gravity fed heating device of the smoking substitute device is located below a tank containing a vaporizable liquid.

15. A method of operating a smoking substitute device, having the steps of:

monitoring, via an accelerometer of the smoking substitute device, a detected orientation of the smoking substitute device;

determining, via the detected orientation, that the smoking substitute device will function improperly;

triggering an alert in response to the determination; and

determining from data indicative of the detected orientation that the smoking substitute device will function improperly when the data indicative of the detected orientation indicates that a gravity fed heating device of the smoking substitute device has been located above a tank containing a vaporizable liquid for a predetermined period of time, wherein the predetermined period of time is at least 30 minutes.

16. The smoking substitute device of claim 1 , wherein the predetermined period of time is within a range from 30 minutes to 180 minutes.

17. The system of claim 11 , wherein the predetermined period of time is within a range from 30 minutes to 180 minutes.

18. The method of claim 15 , wherein determining from the data is defined further as the predetermined period of time is within a range from 30 minutes to 180 minutes.
