Abstract

A semi-covert emergency transmission device and methodology for soldiers and other such personnel requiring pick-up or rescue is disclosed. The device has a flashlight mode and a transmit mode. In flashlight mode, an LED is turned on to provide an illumination source that can be used in numerous applications. In transmit mode, the device uses the same LED to transmit a coded message that includes information relevant to the user. The coded message can be preprogrammed and stored in the device, or translated in real-time. The transmit mode is further configured so as to confirm that the intended user is the one requesting the transmission of the coded message. The light emitted from the LED can be seen for up to a mile or so away by friendly forces or other potential rescuers.

Claims

1. A semi-covert emergency transmitter device, comprising:

a microphone for receiving verbal input, and converting that verbal input to an electrical signal;

a voice recognition module adapted for verifying the verbal input was spoken by an intended user;

a processor adapted to provide a coded message in response to the voice recognition module verifying the verbal input was spoken by the intended user; and

an light emitting diode (LED) for transmitting the coded message provided by the processor.

2. The device of claim 1 further comprising:

an analog to digital converter adapted to convert the electrical signal from the microphone into its digital equivalent and to provide that digital signal to at least one of the processor and voice recognition module.

3. The device of claim 1 further comprising:

a translation module adapted to convert the verbal input into a coded form that can be at least one of stored in a memory of the device and transmitted by the LED.

4. The device of claim 1 wherein the processor is further adapted to provide the coded message only in response to the verbal input being spoken by the intended user a pre-defined number of times.

5. The device of claim 1 wherein the processor has a transmit mode and a flashlight mode, with each mode being initiated by a user input requesting a particular mode.

6. The device of claim 5 wherein in the flashlight mode, the processor turns the LED on to provide an illumination source.

7. The device of claim 1 wherein the coded message is stored in a memory accessible by the processor.

8. The device of claim 1 wherein the voice recognition module is integrated into the processor.

9. A semi-covert emergency transmitter device, comprising:

a microphone for receiving verbal input, and converting that verbal input to an electrical signal;

a verification module adapted for verifying the verbal input was provided by an intended user;

a processor adapted to provide a coded message in response to the verification module verifying the verbal input was spoken by the intended user; and

a light source for transmitting the coded message provided by the processor.

10. The device of claim 9 further comprising:

an analog to digital converter adapted to convert the electrical signal from the microphone into its digital equivalent and to provide that digital signal to at least one of the processor and verification module.

11. The device of claim 9 further comprising:

a translation module adapted to convert the verbal input into a coded form that can be at least one of stored in a memory of the device and transmitted by the light source.

12. The device of claim 9 wherein the processor is further adapted to provide the coded message only in response to the verbal input being spoken by the intended user a pre-defined number of times.

13. The device of claim 9 wherein the processor has a transmit mode and a flashlight mode, with each mode being initiated by a user input requesting a particular mode.

14. The device of claim 13 wherein the light source is an light emitting diode (LED).

15. The device of claim 9 wherein the coded message is stored in a memory accessible by the processor.

16. The device of claim 9 wherein the verification module is integrated into the processor.

17. A method for semi-covert emergency transmission, comprising:

receiving an electrical signal representative of a verbal input;

verifying the verbal input was provided by an intended user; and

in response to verifying the verbal input was spoken by the intended user, transmitting a coded message using a light source, thereby signaling a need for help in a semi-covert manner relative to radio frequency transmissions.

18. The method of claim 17 further comprising:

converting the verbal input into a coded form that can be at least one of stored in a memory of the device and transmitted by the light source.

19. The method of claim 17 wherein verifying the verbal input was provided by an intended user includes performing voice recognition on the verbal input.

20. The method of claim 17 wherein verifying the verbal input was provided by an intended user includes ensuring the verbal input was spoken a pre-defined number of times.
