You see the transducer, the light blue.

When I'm sitting in a submersible though,

This is us chasing it in the submersible.

We went up to them with our submersible.

There's water in between the skull and the transducer.

On the right hand side, you see an ultrasonic transducer.

We attach a transducer, in this case, to the brain, but if it will be a different organ, it will be a different transducer attached to the patient.

But even more incredible was the footage shot from the Triton submersible.

So the ultrasonic transducer emits basically an ultrasonic beam that focuses inside the phantom.

So it consists of two parts, what we call an encoder and a transducer.

The bad news is, this is a semi submersible run by drug cartels.

So we had to chase this in the submersible for quite sometime, because the top speed of this fish is one knot, which was the top speed of the submersible.

But that could just be because the submersible has a wider field of view.

So, when we did this for responses from the standard method and from our encoder and transducer.

Now I want to share with you a little video that I shot from a submersible.

Which means that really is what you would see if you took a dive in a submersible.

I find myself in a Russian submersible two and a half miles down in the north Atlantic,

But the key one really is the encoder alone, because we can team up the encoder with the different transducer.

And the first time I figured out that way was in this little single person submersible called Deep Rover.

I don't know of any other submersible, or even remote, that just takes advantage that this is a three dimensional space.

In 1979 I had a chance to put my footprints on the ocean floor while using this personal submersible called Jim.

So on the left is the encoder alone, and on the right is from an actual blind retina, so the encoder and the transducer.

Since my my first dive in a deep diving submersible, when I went down and turned out the lights and saw the fireworks displays,

So if any of you ever get a chance to take a dive in a submersible, by all means, climb in and take the plunge.

You don't see luminescence until the submersible begins to move forward through the water, but as it does, animals bumping into the screen are stimulated to bioluminesce.

So if you ever, ever get an opportunity to take a dive in a submersible, say yes a thousand times, yes and please turn out the lights.

And then the transducer then makes the output cells send the code on up to the brain, and the result is a retinal prosthetic that can produce normal retinal output.

I first developed this technique working from a little single person submersible called Deep Rover and then adapted it for use on the Johnson Sea Link, which you see here.

You can see, in her case, she's wearing her transducer arrays, one of the front of her chest, one on the back, and then the second pair side to side over the liver.

We capture it in a very special device on the front of the submersible that allows us to bring it up in really pristine condition, bring it into the lab on the ship.

So, you know, here I am now, on the deck of Titanic, sitting in a submersible, and looking out at planks that look much like this, where I knew that the band had played.

The top one is from a normal animal, the middle one is from a blind animal that's been treated with this encoder transducer device, and the bottom one is from a blind animal treated with a standard prosthetic.

The whole notion, then, is one that at the interface there are physical properties in that transducer in this case it's pressure and touches that allow you to present things to the user that you could never present before.

This came out of hundreds of dives I have made, farting around in the dark using these platforms, and my impression that I saw more animals working from the submersible than I did with either of the remote operated vehicles.

So as you can see, the firing patterns from the blind animal treated with the encoder transducer really do very closely match the normal firing patterns and it's not perfect, but it's pretty good and the blind animal treated with the standard prosthetic, the responses really don't.

And then he got so excited, he turned on his flashlight because he wanted to see better, and the giant didn't run away, so he risked turning on the white lights on the submersible, bringing a creature of legend from the misty history into high resolution video.
