Abstract

Described embodiments include a real-time system, method, and apparatus. A system includes an incoming object sensor configured to be worn by a human and to acquire data indicative of a trajectory of an incoming projectile. The system includes a warning device configured to be worn by the human and to provide a notification to the human. The system includes a processing circuit configured to (i) receive the data indicative of a trajectory of the incoming projectile; (ii) predict a spatial relationship of the trajectory of the incoming projectile relative to the human; and (iii) initiate a notification by the warning device suggesting a movement by the human to evade the incoming projectile.

First claim

The invention claimed is:

1. A real-time system comprising:
an incoming object sensor configured to be worn by a human and to acquire data indicative of a trajectory of an incoming projectile relative to the human;
a warning device configured to be worn by the human and to provide a notification to the human; and
a processing circuit configured to:
receive the data indicative of the trajectory of the incoming projectile;
predict a spatial relationship of the trajectory of the incoming projectile relative to the human;
initiate a notification by the warning device suggesting a movement by the human to evade the incoming projectile;
receive data indicative of a movement by the human after the notification of the suggested movement to evade the incoming projectile;
compare the suggested movement with the data indicative of the movement by the human occurring after notification of the suggested movement to evade;
determine an updated suggested movement by the human to evade the incoming projectile; and
initiate a notification by the warning device of the updated suggested movement by the human to evade the incoming projectile.

2. The system of claim 1 , wherein the incoming projectile includes a ballistic projectile or a rocket propelled projectile.

3. The system of claim 1 , wherein the incoming object sensor is configured to be carried by the head of the human.

4. The system of claim 1 , wherein the incoming object sensor includes at least one of an imaging system, a lidar system, a sonar system, or a radar system.

5. The system of claim 1 , wherein the incoming object sensor includes an optical sensor, an infrared sensor, an audio sensor, or a millimeter radar sensor.

6. The system of claim 1 , wherein the incoming object sensor includes a multi-frequency radar sensor.

7. The system of claim 1 , wherein the incoming object sensor includes a Doppler radar sensor.

8. The system of claim 1 , wherein the incoming object sensor is configured to acquire data indicative of a closest approach to the human by the trajectory of the incoming projectile.

9. The system of claim 1 , wherein the incoming object sensor is configured to acquire data indicative of a trajectory of an incoming projectile and a location of a ground impact by the incoming projectile.

10. The system of claim 1 , further comprising:
a head protection gear, wherein the incoming object sensor is coupled to the head protection gear.

11. The system of claim 1 , wherein the warning device is configured to be carried by the head of the human.

12. The system of claim 1 , wherein the warning device is configured to be worn on an appendage of the human.

13. The system of claim 1 , wherein the warning device includes a haptic element configured to generate a stimulus tactilely perceivable by the human.

14. The system of claim 1 , wherein the warning device includes a speaker.

15. The system of claim 1 , wherein the warning device includes a vibratory element.

16. The system of claim 1 , wherein the warning device includes a plurality of warning modules.

17. The system of claim 1 , further comprising:
a head protection gear, wherein the warning device is coupled to the head protection gear.

18. The system of claim 1 , wherein the processing circuit is further configured to predict a proximity and spatial relationship of the incoming projectile relative to the human.

19. The system of claim 1 , wherein the processing circuit is configured to predict a closest approach to the human by the incoming projectile.

20. The system of claim 1 , wherein the processing circuit is configured to predict a trajectory of an incoming projectile and a location of a ground impact by the incoming projectile.

21. The system of claim 1 , wherein the processing circuit is configured to predict a temporal relationship of the trajectory of the incoming projectile relative to the human.

22. The system of claim 1 , wherein the notification by the warning device includes a suggested movement of the human away from the trajectory of the incoming projectile.

23. The system of claim 1 , wherein the notification by the warning device includes an indication of a direction of the incoming projectile.

24. The system of claim 1 , wherein the notification by the warning device includes a generalized notification of the incoming projectile.

25. The system of claim 1 , wherein the notification by the warning device includes an indication of a velocity of the incoming object.

26. The system of claim 1 , wherein the notification by the warning device includes a haptic output.

27. The system of claim 1 , wherein the notification by the warning device includes a vibratory output.

28. The system of claim 1 , wherein the notification by the warning device includes an audible output.

29. The system of claim 1 , wherein the notification by the warning device includes a visual output.

30. The system of claim 1 , wherein the notification by the warning device includes a notification of the incoming projectile and a suggested movement by the human to evade the incoming projectile.

31. The system of claim 1 , wherein the notification by the warning device includes a suggested movement by the human to evade the incoming projectile in advance of a predicted impact of the incoming projectile.

32. The system of claim 1 , wherein the notification by the warning device includes a suggested movement by the human to evade a future incoming projectile responsive to the predicted spatial relationship of the trajectory of the incoming projectile relative to the human.

33. The system of claim 1 , wherein the notification by the warning device includes a suggested movement by the human to evade an incoming projectile on a round-by-round basis (e.g., for mortars and grenades, or for bullets) responsive to the predicted spatial relationship of the incoming projectile relative to the human.

34. The system of claim 1 , wherein the notification by the warning device includes a suggested movement by the human to evade an incoming projectile on an aggregate basis (e.g., for a burst of bullets) responsive to the predicted spatial relationship of the incoming projectile relative to the human.

35. The system of claim 1 , further comprising a body orientation sensor configured to acquire data indicative of a current orientation of a body part of the human.
