Abstract

Sensor data indicative of a user'"'"'s environment is received from a sensor. A video signal is generated which comprises a visual representation of the sensor data. The video signal is combined with a night vision view of the user'"'"'s environment to overlay the visual representation of the sensor data over the nigh vision view of the user'"'"'s environment. The overlaid night vision view of the user'"'"'s environment is displayed to the user.

Claims

1. An apparatus comprising;

a display device configured to provide a night vision view of a user'"'"'s environment;

a sensor configured to generate sensor data indicative of the user'"'"'s environment; and

a video generator configured to receive sensor data from the sensor and provide a video signal comprising a visual representation of the sensor data to the night vision display device,

wherein the night vision display device is configured to display an image corresponding to the video signal overlaid with the night vision view of the user'"'"'s environment.

2. The apparatus of claim 1, wherein the sensor comprises a gunshot detector configured to generate sensor data indicative of the location of a gunshot.

3. The apparatus of claim 2, further comprising a global positioning system receiver, providing global positioning information to the video generator,

wherein the video generator is configured to provide the video signal in response to the location information for the gunshot and the global positioning information.

4. The apparatus of claim 1, wherein the sensor comprises at least one of a global positioning system receiver, a vehicle diagnostic sensor, or a light detection and ranging device.

5. The apparatus of claim 1, wherein the night vision display device comprises a night vision goggle.

6. The apparatus of claim 5, wherein the night vision goggle is configured to provide a binocular image to the user.

7. The apparatus of claim 5, wherein the night vision goggle is configured to provide a bi-ocular image to the user.

8. The apparatus of claim 1, wherein the night vision display is configured to provide a monocular image to the user.

9. The apparatus of claim 1, wherein an eye piece of the display is configured to block light emitted from the display from leaking into the user'"'"'s environment.

10. The apparatus of claim 1, wherein the sensor data comprises a digital serial signal.

11. The apparatus of claim 1, wherein the video generator is embodied in a smartphone.

12. The apparatus of claim 1, wherein the video generator is embodied in at least one of an application specific integrated circuit, a field programmable gate array, a microcontroller, or a microprocessor.

13. The apparatus of claim 1, wherein the sensor data comprises non-visual data.

14. The apparatus of claim 1, wherein the night vision display device comprises a phosphor screen and a transparent display, wherein:

the night vision view is displayed from the phosphor screen and the video signal is displayed from the transparent display, and

the transparent display is arranged on a user-side of the phosphor screen.

15. A method comprising:

receiving sensor data from a sensor indicative of a user'"'"'s environment;

generating a video signal comprising a visual representation of the sensor data;

combining the video signal with a night vision view of the user environment to over lay the visual representation of the sensor data over the night vision view of the user'"'"'s environment; and

displaying the overlaid night vision view of the user'"'"'s environment.

16. The method of claim 15, wherein receiving sensor data comprises receiving sensor data from a gunshot detector indicative of a location of a gunshot.

17. The method of claim 16, further comprising:

receiving global positioning information,

wherein generating the video signal comprises overlaying a location of the gunshot over the night vision view of the user'"'"'s environment in response to the location information for the gunshot and the global positioning information.

18. The method of claim 15, wherein displaying the overlaid night vision view comprises displaying a binocular image.

19. The method of claim 15, wherein receiving the sensor data comprises receiving non-visual data.

20. An apparatus comprising:

a display device configured to provide a night vision view of a user'"'"'s environment;

a gunshot detector configured to generate sensor data indicative of a location of a gunshot; and

a video generator configured to receive sensor data from the gunshot detector and provide a video signal comprising a visual representation of the sensor data to the night vision display device,

wherein the night vision display device is configured to display an image corresponding to the video signal overlaid with the night vision view of the user'"'"'s environment.
