Abstract

A personal security device is disclosed that permits a person in distress to alert people adjacent the person that a problem has occurred. The device may include an alarm circuit that may be activated by the person in distress of when the device is removed from the person in distress. The alarm circuit may be an audible alarm (80-125 decibels) circuit, a visual alarm circuit, an odor alarm, an electronic signal generation circuit or may generate a tracking signal.

Claims

1. A watch, comprising:

a watch body;

a watch module located within the watch body that displays a time of day;

an alarm circuit located within the watch body;

a power source located in the watch body that provides power to the alarm circuit;

one or more alarm buttons located on the watch body wherein activation of the one or more alarm buttons generates an alarm signal; and

a controller circuit that, in response to the alarm signal, controls the alarm circuit to generate an audible alarm with a volume of between 80 and 120 decibels.

2. The watch of claim 1, wherein the alarm circuit further comprises one or more light sources that generate a visual alarm.

3. The watch of claim 2, wherein the one or more light sources further comprise light emitting diodes.

4. The watch of claim 2, wherein the light sources are controller by the controller circuit to generate a predetermined pattern of visual signals.

5. The watch of claim 1, wherein the alarm circuit further comprises a mechanism to generate an odor when the alarm signal is activated.

6. The watch of claim 1, wherein the alarm circuit further comprises a transmitter that generates an electronic signal when the alarm signal is activated.

7. The watch of claim 1, wherein the alarm circuit further comprises a tracking circuit so that the watch is trackable when the alarm signal is activated.

8. The watch of claim 7, wherein the tracking circuit further comprises a global positioning system unit.

9. The watch of claim 7, wherein the tracking circuit further comprises a cellular-based tracking unit.

10. The watch of claim 1, wherein the alarm circuit further comprises a removal circuit that detects removal of the watch from the user and generates the alarm signal.

11. The watch of claim 10, wherein the removal circuit further comprises a wire embedded into a strap of the watch.

12. The watch of claim 1, wherein the alarm circuit further comprises a piezo element that generates sound waves and a Helmholtz chamber that amplifies the sound waves to generate the audible alarm.

13. The watch of claim 12 further comprising a boost circuit within the watch body that boosts the voltage generated by the power source to drive the piezo element.

14. The watch of claim 12, wherein the Helmholtz chamber comprises:

a base; and

a sidewall having at least one hole to allow sound to travel out of the Helmholtz chamber.

15. The watch of claim 1, wherein the power source further comprises one or more of a battery, a solar cell and a combination of a battery and a solar cell.

16. A personal security device, comprising:

an alarm circuit located within the device;

a power source located in the device that provides power to the alarm circuit;

one or more alarm buttons located on the device wherein activation of the one or more alarm buttons generates an alarm signal; and

a controller circuit that, in response to the alarm signal, controls the alarm circuit to generate an audible alarm with a volume of between 80 and 120 decibels.

17. The device of claim 16, wherein the alarm circuit further comprises one or more light sources that generate a visual alarm.

18. The device of claim 17, wherein the one or more light sources further comprise light emitting diodes.

19. The device of claim 17, wherein the light sources are controller by the controller circuit to generate a predetermined pattern of visual signals.

20. The device of claim 16, wherein the alarm circuit further comprises a mechanism to generate an odor when the alarm signal is activated.

21. The device of claim 16, wherein the alarm circuit further comprises a transmitter that generates an electronic signal when the alarm signal is activated.

22. The device of claim 16, wherein the alarm circuit further comprises a tracking circuit so that the device is trackable when the alarm signal is activated.

23. The device of claim 22, wherein the tracking circuit further comprises a global positioning system unit.

24. The device of claim 22, wherein the tracking circuit further comprises a cellular-based tracking unit.

25. The device of claim 16, wherein the alarm circuit further comprises a removal circuit that detects removal of the device from the user and generates the alarm signal.

26. The device of claim 25, wherein the removal circuit further comprises a wire embedded into a strap of the device.

27. The device of claim 16, wherein the alarm circuit further comprises a piezo element that generates sound waves and a Helmholtz chamber that amplifies the sound waves to generate the audible alarm.

28. The device of claim 27 further comprising a boost circuit within the device body that boosts the voltage generated by the power source to drive the piezo element.

29. The device of claim 27, wherein the Helmholtz chamber comprises:

a base; and

a sidewall having at least one hole to facilitate sound travel out of the Helmholtz chamber.

30. The device of claim 16, wherein the power source further comprises one or more of a battery, a solar cell and a combination of a battery and a solar cell.

31. The device of claim 16 further comprising a watch module.
