Came from it. >> and how does this make for a better bike ride for you? >> well, for me, i commute over the bridge to manhattan ever every morning and it is interesting to see the hot spots, and what intersection or the street that does not have a bike lane that needs one. >> and you were saying that you like it when the light turns red and tell us why. >> well, definitely. it is different for every psyche clis, but for me in particular i will see a lot more red when im more energetic and in a w...

Disobedience. in beijing today there is a real sense of historical amnesia. >> reporter: back then the students demonstration against corruption and inequality and lack of basic political freedom was crushed by the military. and the men who ruled china from the buildings around the famous square also known as the gate of heavenly peace. these days the tanks are replaced by an army of digital sensor whose wipe out any public mention of the tiananmen square crackdown. >> an incredibly massive unde...

Patty has that. >> it was almost a tragedy. an alaska airline jet carrying 148 people was about to land in the anchor age international airport. they were ordered to do a go around. the plane veered right. the prop jet was taking off and came within a quarter mile at the same height. the boeing 737 collision avoidance sensor went off. they are trying to find out what went wrong. this comes of another near mess on houston. >> the jets came a mile from taking off in george buchlt international air...

You dont have to run back and forth to the doctor all the time. >> how does it work exactly? >> well, essentially the same way theyve always worked only its taking the computer out of the device youre wearing. so any time you have a heart monitor, theres a sensor and a computer. now we all carry computers in our pockets. so they are building sensors that are small enough to be woven into fabric which cuts down the barrier to entry for any of us too lazy to go buy a heart monitor, right? >> it is...

And silt, how challenging is it for the search? >> reporter: don, you can see were out on the boat, i want to introduce you. just -- the indian ocean weve there.how rough it is to work can you put it in perspective for us? >> from a sonar perspective it is actually a good environment, it is very deep, you want to get the sonar down very deep. but the complexity of the depth, to get the sonar down deep you have to put it on the auv. it has to have navigation, communications and dive down deep. it...

How it works. >> right, this is side scan sonar, what the sensor is doing is put sound out. it generates an image of what is on the sea floor. >> and so anderson, it is interesting because the closer down they get the better that image can be, but the higher up the more they can see what is underneath them. so it can be a tedious process of changing the mission to get a better idea of what is down there. >> i have a question, are they getting realtime images or just data. i thought it was data t...

Theyre using sonar that is made by your company. its a different kind. but can you show whats this mapping looks like when they get that image back? can we go inside and look at that so we get an idea. >> first of all, theyre building a -- weve already seen this mow the lawn pattern. thats what weve been doing here today. we have a grid pattern here. the boat is over here. weve been mowing along. and slowly building up a map of different things that are on the sea floor. this is what the mission...

Its very challenging. >> lets go inside. i want to take a look at how this looklooks. once the sonar is down there it has got to take some data back. >> the idea is to move the sensor back and forth in a regular grid pattern. were moving along now. you see that we did one line previously. as you do youre building up a map of whats on the sea floor. were seeing in realtime the auv. they only see it at the end of their mission. >> they are sort of flying blindly? >> in a way, yes. they will make t...
