Emergency message button and method on a wireless communications device for communicating an emergency message to a public safety answering point (PSAP)

1. A wireless communications device, comprising:

a housing;

a user interface disposed on said housing configured to enable a user to type text messages for communication over a communications network;

at least one illumination device comprising an electronic display;

an emergency message button selectable by a user; and

a processing unit in communication with said user interface and emergency message button, and configured to:

determine whether a user has selected said emergency message button, based on a determination that a force applied to the emergency message button exceeds a first threshold force, wherein the first threshold force is greater than a second threshold force required to actuate the user interface for typing text messages;

generate and send an emergency message to a public safety answering point in response to a determination that a user has selected said emergency message button; and

in further response to the determination that a user has selected said emergency message button, set said at least one illumination device into an emergency mode, the emergency mode reducing or eliminating illumination of said at least one illumination device; and

display an acknowledgement notification signal of the selection of the emergency message button as text on a black background on the electronic display.

2. The wireless communications device according to claim 1 , wherein said emergency message button is a hard-button disposed on said housing.

3. The wireless communications device according to claim 2 , wherein said emergency message button is recessed with respect to a surface of said housing.

4. The wireless communications device according to claim 1 , wherein said emergency message button is a soft-button displayed on said electronic display.

5. The wireless communication device according to claim 1 , wherein said processing unit is configured to identify a predetermined sequence of activations by the user to indicate an intentional emergency request.

6. The wireless communications device according to claim 5 , wherein the predetermined sequence is three activations within one second of time.

7. The wireless communications device according to claim 1 , wherein said emergency message button also functions as a power on/off button.

8. The wireless communications device according to claim 1 , wherein said processing unit is further configured to generate and send an emergency message to a public safety answering point in response to a user selecting said emergency message button and another button substantially simultaneously.

9. The wireless communications device according to claim 1 , wherein said emergency message button has a first threshold force for activation that is higher than a second threshold force for activation of buttons of said user interface.

10. The wireless communications device according to claim 1 , wherein said processing unit is further configured to:

determine whether the wireless communications device is currently powered on; and

in response to determining that the wireless communications device is currently powered on, perform an abbreviated power-up sequence.

11. The wireless communications device according to claim 10 , wherein the abbreviated power-up sequence includes turning on a limited number of components of the wireless communications device.

12. The wireless communications device according to claim 1 , wherein said processing unit is further configured to lower or eliminate volume of the wireless communications device.

13. A method for enabling a user to send an emergency message from a wireless communications device, said method comprising:

providing an emergency message button on the wireless communications device;

determining whether a user has selected said emergency message button, based on a determination that a force applied to the emergency message button exceeds a first threshold force, wherein the first threshold force is greater than a second threshold force required to actuate a non-emergency button on the wireless communications device for typing text messages; and

in response to a determination that a user has selected the emergency message button,

causing an emergency message to be generated and sent to a public safety answering point; and

setting at least one illumination device into an emergency mode, the illumination device comprising an electronic display, the emergency mode reducing or eliminating illumination of said at least one illumination device; and

displaying an acknowledgement notification signal of the selection of the emergency message button as text on a black background on the electronic display.

14. The method according to claim 13 , wherein providing an emergency message button includes providing a hard-button.

15. The method according to claim 14 , wherein providing the hard-button includes providing a recessed hard-button.

16. The method according to claim 13 , wherein providing an emergency message button includes providing a soft-button displayed on the wireless communications device.

17. The method according to claim 13 , further comprising identifying user selection of the emergency message button by identifying a predetermined sequence of activations by the user to indicate an intentional emergency request.

18. The method according to claim 17 , wherein the predetermined sequence is three activations within one second of time.

19. The method according to claim 13 , further comprising providing an emergency message button including enabling a power on/off button to additionally function as an emergency notification button.

20. The method according to claim 13 , wherein causing an emergency message to be generated is in response to the user selecting the emergency message button and another button substantially simultaneously.

21. The method according to claim 13 , further comprising turning on and off at least one illumination device in response to the emergency message being sent to notify the user that the emergency text message was sent.

22. The method according to claim 13 , further comprising:

determining whether the wireless communications device is currently powered on; and

in response to determining that the wireless communications device is currently powered on, performing an abbreviated power-up sequence.

23. The method according to claim 22 , wherein performing the abbreviated power-up sequence includes turning on a limited number of components of the wireless communications device.

24. The method according to claim 13 , further comprising lowering or eliminating volume of the wireless communications device.
