. >> those same microwave signals were redesigned at jpl for an even more urgent endeavor here on earth. do search for, for a trapped survivor by detecting their beating heart. >> the return signals were looking for small changes due to the motion of the victim, the breathing and the heart beat causes one centimeter to one millimeter movements. we look for the reflexes of that. so we are looking for the changes of that due to the heart beats. >> finder or finding individuals for disaster and emergency response is the remarkable new technology resulting from the collaboration between jpl, female, and homeland security. it is capable of recognizing a victim's heart bate and res pration through 30 feet of concrete and debris. >> basically measuring how far it is from the finder unit to the victim's heart and then back. finder works on an unconscious victim. as long as your heart is beating and your breathing, we can detect you. >> within a year, two prototypes were up and running and ready for field testing. >> tell me what it is? >> this is finder. it's a victim detention radar that uses

the value of iran's currency has decreased by about 7% since the jpl a was announced last december. it has lost about $120 billion in oil revenues. it lost about 120 billion in the first few months. it stands to lose more in the next four months. iran's economy today is 25% smaller than it would have been had it remained on its pre-2011 growth trajectory. when we just -- when we entered into the jpoa, some argued that iran's economy would rebound. our sanction regime remains above and iran's economy continues to struggle. we remain confident that four months from now, our sanctions will continue to bite and iran's economy will continue to be in distress. it may provide iran -- may pale compared with what iran needs to dig itself out of the deep economical. firms have good reason to remain reluctant about doing business in iran. the overwhelming majority of sanctions remain in place. iran remains to be cut off from the international financial system and is largely unable to attract foreign investments. iran is still shut out of the united states, the world's largest and most vibrant

the science was so wonderful that that's what they wanted to talk about, the jpl. not about the damage that the pictures were there. they are our craters every solid object. >> host: it's an amazing thing. such universal process. obviously if you have a very thick atmosphere that keeps craters from being formed and there are some places that are just volcano world but that's a minority. most places are pelted by these objects all the time. all of these objects all the time and in fact it's an amazing tool because things get hit at a certain rate and once we have figured out what that rate was by measuring the ages of the feature on the moon by the apollo program you could extend that to all the other objects that were being pelted. so this is sort of like how do you look at the surface of a planet and tell how old it is? without going down and picking up a sample and dating the rocks. you can just look at it and it's a wonderful tool. so yeah you have your volcano world's. you have got your impact worlds and the moon has gone back and forth. they thought it was vol

there are lots of academic labs and most notably jpl out in california is trying to develop what they call terrain-relative navigation. but all of these budgets, i hate to beat that horse, but all of these budgets just took a recent big hit, and unless this country puts more emphasis into terrain-relative navigation or gps-free technologies, we're not going to be able to get over that hurdle. but, again, it's not just an unmanned vehicle hurdle, this is also a commercial aircraft hurdle. >> yeah, you raise an important point which i won't comment on just now, but, i mean, we are constraining what we can do in the future by our decision making. you said that you weren't much of an expert on arrives, but i want -- on privacy, but i want you to make yourself one for the moment and reflect on what you've heard here today. >> well, i didn't say i wasn't an expert on privacy, i knew there would be so much discussion about it today that i didn't want to jump on that bandwagon too soon. i do think all these privacy issues are important. but, again, i think we lose sight of the drones as a tec
