Helicopter hoist systems, devices, and methodologies

1. A method for disseminating helicopter-hoist information on a display device, comprising:

measuring with a range measuring device a height of a helicopter relative to ground or water directly under the helicopter;

measuring with a load sensor a load on a rescue cable;

measuring with the range measuring device a height of a rescue hook above the ground or water;

receiving streaming video from a camera of a target rescue area including the rescue cable and the rescue hook;

displaying on the display device the received video stream;

overlaying on the display device of the streaming video a first virtual marker indicating the height of the rescue hook above the ground or water on the video stream in proximity to a hook end;

overlaying on the display device of the streaming video a second virtual marker indicating the height of the helicopter relative to the ground or water on the video stream proximity to the helicopter; and

overlaying on the display device of the streaming video a third virtual marker indicating the load on the rescue cable on the video stream in proximity to the rescue cable.

2. The method of claim 1 , further comprising: measuring a hook location in three-dimensional coordinate space relative to the helicopter and displaying a fourth virtual indicator in proximity to the hook location indicating the three-dimensional coordinate space.

3. The method of claim 1 , further comprising overlaying a first virtual color over an image of the rescue cable from the received streaming video when the measured load is below a maximum weight limit on the rescue cable.

4. The method of claim 1 , further comprising overlaying a second virtual color over an image of the rescue cable from the received streaming video when the measured load is below a maximum weight limit on the rescue cable and over a threshold representing that the load on the rescue cable is near the maximum limit.

5. The method of claim 1 , further comprising overlaying a third virtual color over an image of the rescue cable from the received streaming video when the measured load exceeds a maximum weight limit on the rescue cable.

6. The method of claim 1 , further comprising displaying rescue checklists on the display device.

7. The method of claim 1 , further comprising displaying virtual arrows on the received video stream indicating a direction of travel of the rescue cable.

8. A method for helicopter rescue, comprising:

providing a housing having a cable end for attachment to a rescue cable, and a hook end for attachment to rescue equipment, the housing further including an outer surface and at least one lighting device disposed on the housing;

measuring with a load sensor a load between the hook end and the cable end;

measuring with a range measuring device an altitude of the housing above the ground or water;

illuminating the at least one lighting device with at least one of an illumination pattern, flash frequency, and color emitted from the lights based on at least one of the measured load on the cable and altitude of the housing relative to the ground.

9. A helicopter-hoist system comprising:

hoist equipment including a motor and a cable configured to be mounted to a helicopter;

an illumination system for illuminating areas below the helicopter;

range-measuring equipment, for measuring distance between the helicopter and surfaces below the helicopter;

one or more cameras for recording images below the helicopter;

a processing system configured to control an operation of the one or more cameras, the range-measuring equipment, and the illumination system;

a smart-hook containing a load cell configured to measure a load on the smart-hook, the smart-hook further comprising a plurality of lights associated with the housing thereof, wherein the processing system is further configured to modify at least one of the following:

an illumination pattern, flash frequency, and color emitted from the plurality of lights based on the measured load on the smart-hook; and

one or more display devices in communication with the processing system, configured to display real images received from the one or more cameras;

wherein the processing system is further configured to record the measured parameters appurtenant to a location of the smart-hook and the load on the smart-hook, and render virtual information proximate to or over the real images.

10. The helicopter-hoist system of claim 9 , further comprising an aerodynamically-shaped cowling for encasing the hoist equipment, the illumination system, the range-measuring equipment, the processing system, and the one or more cameras.

11. The helicopter-hoist system of claim 9 , further comprising an active load control system wherein the processing system is configured to receive real-time load and acceleration data from the smart-hook and adjust a payout of the cable to actively dampen vibrations imparted to the hoist equipment and the helicopter.

12. A method for disseminating helicopter-hoist information on a display device, comprising:

measuring with a range measuring device a height of a helicopter relative to ground or water directly under the helicopter;

measuring with a load sensor a load on a rescue cable;

measuring with the range measuring device a height of a rescue hook above the ground or water;

receiving streaming video of a target rescue area including the rescue cable and the rescue hook from a camera;

overlaying on a display device at least one of the following: a first virtual marker indicating the height of the rescue hook above the ground or water on the video stream in proximity to a hook end; overlaying a second virtual marker indicating the height of the helicopter relative to the ground or water on the video stream in proximity to the helicopter; overlaying a third virtual marker indicating the load on the rescue cable on the video stream in proximity to the rescue cable; and

displaying, the received video stream combined with at least one of the following: overlaid first, second and third virtual indicators.

13. The method of claim 12 , further comprising: measuring a rescue hook location in three-dimensional coordinate space relative to the helicopter and displaying a fourth virtual indicator in proximity to the rescue hook location indicating the three-dimensional coordinate space.

14. The method of claim 12 , further comprising overlaying a first virtual color over an image of the rescue cable from the received video stream when a measured load is below a maximum weight limit on the rescue cable.

15. The method of claim 12 , further comprising overlaying a second virtual color over an image of the rescue cable from the received video stream when the measured load is below a maximum weight limit on the rescue cable and over a threshold representing that the load on the rescue cable is near the maximum limit.

16. The method of claim 12 , further comprising overlaying a third virtual color over an image of the rescue cable from the received video stream when the measured load exceeds a maximum weight limit on the rescue cable.

17. The method of claim 12 , further comprising displaying rescue checklists on the display device.

18. The method of claim 12 , further comprising displaying virtual arrows on the received video stream indicating a direction of travel of the rescue cable.
