Now on bbc news, click. This week, portable ultrasound scanners, brain music, and robot dogs that clean up after themselves. Theme music. Over the years on click we have seen devices get smaller and smaller. Yet with more storage and more processing capabilities. This miniaturisation of devices has touched everything from our computers to phones and even revolutionising areas of medicine. One area of medicine which has a lot of demand and could potentially benefit from miniaturisation is medical imaging. In the uk, over 41 million scans take place every year in the nhs using x rays, mri and ultrasound. In an emergency, at the bedside or even in an ambulance, it can be complicated to get a patient to one of these large machines. But now, portable medical devices made in the uk could change our lives, giving doctors and patients instant access to ultrasound at a reduced cost. The intensive care unit of southampton Childrens Hospital admits hundreds of patients each year, with a range of medical conditions from Heart Disease to trauma and neurological emergencies. Effie was admitted with a lung infection and needs constant monitoring with tests, x rays and ultrasounds. Usually these are performed by expert radiologists and they arent always immediately available. This ward has four point of care ultrasound machines. These two cost over £50,000 each. But now the same test can be carried out using a Smartphone App and probe, which fit into a doctors pocket and cost a fraction of the price. She had heart surgery yesterday for a condition which is a problem in the heart where there are four different issues. One of the complications of that is sometimes fluid around the lungs. So at southampton we routinely do an ultrasound scan of childrens chests before taking out chest drains and to make sure that all the fluids gone. This ultrasound system is called the butterfly, and consists of a hand held probe which attaches to an i0s smartphone or tablet. This is now filming where the lung meets the diaphragm. Well, that lung looks completely normal. There is no fluid around the lung, there is no fluid in the lung, the lung is moving well. It costs only £1699 a fraction of the cost of the larger machines. And its small footprint means its less invasive at a childs bedside. One of the problems with most ultrasound machines is that theyre designed with adults in mind. And so all of the presets are designed for adults. What weve actually got here is a whole variety of paediatric settings as well. So i can select paediatric lung, paediatric heart, paediatric abdomen, but i could also flip and standard adult lung, it nowjump between one probe with the press of a button rather than changing the probes in that ultrasound machine over and over to get the right probe. Lets get rid of the jelly. Well done. Traditional ultrasound machines use piezoelectric crystals, individuals crystals cut into different shapes and sizes as different frequencies are used to image different parts of the body. But this also means that different probes are needed. The butterfly uses ultrasound on a computer chip and needs only one probe for different body parts. We are the worlds first ultrasound on chip, a single probe whole body imaging system, instead of the typical 124 imaging elements that are in a pzt probe, there are almost 9,000 elements in this. And so we can recreate all the different types of probes with just one. And that becomes really important as you scan different areas of the body in an emergency, you dont have to keep shifting probes. Just a simple change within the application itself you can go from heart and lungs very quickly and make rapid decisions on whats actually wrong with the patient. The information from the app can be anonymously sent to a secure server for different doctors to review quickly. The implications for Global Health for a portable and relatively cheap solution for scanning are clear. An estimated 5 billion people around the world dont have access to medical imaging of any kind. In sub saharan africa, the device is being used to check for pneumonia, the leading infectious cause of death in children under five. In fact, the companys chief medical officer made his own alarming discovery when scanning himself during the devices testing. When we were doing the studies for fda clearance, i noticed some fullness in my neck, i put the probe up to my neck and looked at my phone and i shockingly saw a very large mass which ultimately turned out to be a metastatic cancer. Yeah. So im patient number one of the butterfly and living proof that having an immediate access to an image can change your health and your life. Southampton has bought four of the devices and plan to always have one available in its childrens ambulance. When you are in front of a child that is critically unwell and you desperately need information, and you are relying on a third person, and youre watching a child deteriorate and you feel powerless. Actually, this gives you the power. This gives you the information to look inside to keep the kids chest. It gives information to look at their heart. You can decide for yourself within seconds. And suddenly, looking after Sick Children is a bit less scary. For now, the butterfly is only available to medical professionals. But tests are currently underway with a group of cardiac patients scanning themselves at home. The Artificial Intelligence built into the device will help guide the patient of the right area to scan, and perhaps with regulatory approval, one day, at home ultrasound scans could be a reality. Tate modern in london opens a major show of the work of the korean visionary nam june paik, which brings over together 200 of his pieces. Here is someone who made a career of being ahead of his time. He was the ultimate early adopter. He came up with the idea of wearable tech, codeveloped the first video synthesiser in 1970. He coined the term electronic superhighway in 1976. And, he vjed a live global videocast via satellite in 1974. Hang around, and later well have a closer look at this strange experience. Although paik was korean, he spent an awful lot of time injapan. And a lot of his work is influenced by japanese culture. I mean, no one loves a robot more than the japanese, am i right . And in fact, japan is where we are heading now for its annual tech extravaganza ceatec. Dan simmons and emily bates are waiting for us on the show floor. Modulated hello, and welcome back to ceatec. This is ridiculous. Some things that japans annual tech shindig can leave visitors speeches, unfortunately, not so for emily. I have no idea what im doing. Laughs. Now, over to the kitchen, is your robot dog trying to tell you something . Sonys aibo is now faithful to hitachis appliances. If you leave the fridge door open or the washing machine finishes its cycle, he will come over and find you and bark and wag his tail because an alarm going off isnt as cute and wont sell products. He even rides the robot cleaner, just like real dogs. And with these transparent tv screens from sharp, shop windows may never be the same again. Ok, this is something im personally quite interested in and excited about. Its something i think its something many of us have been waiting for four years. And murata think that theyve cracked it. How do we know whether weve got a cold or weve got a virus or maybe whether its a bacterial infection . 0ften our doctors take best guesses but they dont really know. And part of the reason for that is any sample they take, if they do, takes a few hours or maybe even a couple of days to tell us what weve got. Murata and Osaka Prefecture University have created a portable device that gathers bacteria, making it quicker and easier to analyse. A laser is pointed underneath the sample that is on a substrate, basically a plate that is based on this device, and we can see here what the microscope is seeing. Now, look closely and you will see the movement of the water that surrounds the sample. The sample can be food if we want to detect something that could cause food poisoning, or something in blood or in urine or spittle or any sort of substance that we might analyse from the human body. The movement of water is causing a concentration of the bacteria, or indeed the virus, down towards the bottom towards that plate. So theres no need to grow anything. Theres no need to look too closely because everything is concentrated ina smallarea. This is about the size of a mobile phone. The idea is that could be deployed into field clinics, into our gp surgeries, and the results of that, they are saying, would come back within minutes 7 not ours, they are saying, would come back within minutes, not hours, not days, but within a few minutes. Its still early stages, so dont expect anything for two years or 0. It is easy to see the impact it could make. Sony devoted its entire stand to health tech this year. Including this cell analyser that tracks biomarkers which can help detect cancer and uses lasers that may be familiar to you. We are actually using the blu ray players technology. We are detecting the cancer by laser and then detecting the scattered light from the cells. That is exactly the same as blu ray players. Dan, what on earth is going on over here . Just trying a little bit of surgery. Surgery . Mmm. Are you a brain surgeon now . With these 3d glasses and a 3d screen there, this is one of the best resolutions for any surgery. This is actually used, this camera here is actually used in surgeries. And the trick is not to look down at what you are doing inside this brain, for example, it is to keep looking up at the screen and still youve got the peas that you want. Very good and then, look at how small that is that is absolutely tiny. Look at this. That is so small. Im no brain surgeon, emily, i can tell you. Im busted. This is childs play. And finally, dan found a visible way to converse with the locals here they didnt involve flapping his arms around. Konichiwa, hajimemashite. No idea what that means, but with a swipe of the finger, theres the japanese. And theres the english. Hello, nice to meet you. Hello and welcome to the week in tech. It was the week that a robotic hand solved a rubiks cube. Developed by open ai, it took about four minutes to complete the challenge. The uk government dropped plans to use strict vilification checks to use strict age verification checks to stop under 18s viewing porn online. And nasa unveiled their newest line of spacesuits. An engineer showed off the flexibility of the prototype suit by twisting and bending at the waist, unlike suits in the past. It was also the week that fortnite disappeared and came back again for its new season. Over the weekend a meteor shower took place in the popular game, with a black hole being the only thing on screen. But the game finally became able to play again 48 hours later as the next season launched. Facebooks proposed cryptocurrency project libra has seen 7 of the 28 original Member Companies pull out. Booking. Com was the latest to leave on monday. However, a spokesperson from the social Media Company says they are still planning to launch next year if approval from finance regulators worldwide is granted. And finally, theres now a robotic solution to help you move a box from one place to another. Agility robotic are showing off their newest version of digit. Using cameras and lidar, it can identify a package by reading barcodes on it, sense and avoid obstacles as it walks, and place it at its final destination. Now, google held an event in new york where it gave more details about its latest pixel phone, as well as a few other things. The pixel 4 and 4 xl have been announced. Shipping on 2a 0ctober, their latest and most powerful generation of phones feature an astrophotography camera mode, to take pictures of the night sky. They say it works by automatically creating a mix of 15 Long Exposure shots. The whole process can take about four minutes to complete. Google also announced a new smart speaker, the nest mini, which includes an extra chip. The company says it allows it to process more commands within the device rather than on remote computer servers. The latest version of pixel bud earphones were revealed, which google says will connect to the new phones from a distance of up to a football pitch away. And their Video Game Streaming Service stadia also got a shout out, with a release date of 19 november. 0k, back to tate moderns retrospective on the work of korean born namjune paik, one of the first artists to use electronic terminology in his art. Nam june paik was one of the artists who worked with mainstream entertainment figures, like david bowie, and he was very interested in showing no boundaries between high art and mass culture. So in a way he has shown a lot of things like mtv before it was available, but also youtube and other things. He understood those personal connections and communications were important in bringing people together beyond any national or cultural boundaries. Electronics superhighway was one of the terms he coined as early 3519711, and he thought that connecting different cultures and connecting different people in Different Countries could actually help people understand and avoid conflict. Although paik is well known as being a pioneer of video art, he is also a pioneer of interactive art. This from the 1960s is three camera participation, where the there viewer of the work necessarily becomes part of it. Way back in 1963, namjune made a work called random access, which showed that a linear medium like audio recordings could be non linear. It consisted of strips of audiotape and a portable cassette player with an extended magnetic tape head that could be dragged over the strips in any direction. He employed tvs as an artistic medium for the first time. Tvs were very expensive electronic machines then, and only a few families could actually afford tvs in their household. Paik was certainly way ahead of his time, so i wonder what he would have made of what emily and dan have found injapan . What could possibly go wrong . This is a single seater, sort of, flying ship. You have got to want to make this happen, people this is brilliant hello. That was amazing the team takes part in a global competition, for real, in the us in february. In summer we saw nec lift off its flying taxi. After the excitement of that initial launch, it feels like things are slowing down here. And that is because things like the infrastructure to actually get these off the ground in cities simply isnt in place at the moment. Nec say they are working with the japanese government to hopefully get uncrewed version of these off the ground and in cities by 2023, which would be pretty impressive. Last week we were talking electric cars and heres an idea to recycle the batteries. 0ne autumnal nissan leaf can still store enough solar energy to power 12 of these reborn streetlights. 200 are planned for next year. You can also charge your phone from them, which is useful in disaster situations, like the one japan had last weekend with the typhoon. Now take a look at these, underneath my feet. They are solar panels, and they are charging that electric car. It seems like a bit of a no brainer, these can hold up to 20 tons, very useful, and i think the company producing them believe that by 2022, we could have roads made of these, so you can be charging up while youre driving. Murata showed off a clever holographic style image that you can actually feel. 0h laughs. That is really weird. I wouldnt normally stroke a jellyfish. Dozens of piezoelectric actuators and micro blowers direct vibrations through the air to match up with where the image appears to be. Over at Mitsubishi Electric you had a holographic sign you could jump through, but how about this a projection that replaces a vending machine or atm . It is more hygienic, and all they need to do now is make the money appear out of thin air. Meanwhile, i am riding a dustbin lid. Itjust doesnt like Going Forward tdks 6 axis sensor gaming disc could be the future, but i am not so sure. I am really not very good at this. Emily and dan injapan. Now when we are feeling joyous, sad, angry, we try and find music to fit the mood. Not sure that is it right now if i am honest, but what if you could guarantee to find the right song for the moment . Well that is what lj rich has been looking at. Here is a personalised station of party songs. Voice activated technology is finally good enough to capture our imagination, and with smart speakers letting us hear virtually any song on command, it has made music more consumable than ever before. Today, sonos are showing off their products with some Unexpected Technology art installations totally up my street. My favourite part of this exhibition is the chance to see what my brain does when listening to music. Now, normal brains emit lots of electrical activity reduced down to the basics, you could say, they have five main states. For example, normal alertness would likely generate beta waves. And being relaxed or in a light meditation, alpha waves. Willing participants wear an eeg for a rudimentary real time scan. Sensors pick up the dominant waveform and use that data to inform the visuals. Now as we all experience music differently, the visuals change across each person, based on how each mind processes the stimulus. So with the help of this brain headset, i can find out what my feelings look like. It feels like staring at our brainwaves could offer a way to change our moods, much like choosing what to eat at a restaurant, so i am not surprised to be offered a menu by gabe, one of the brains behind the installations. Gentle piano music plays. It is incredibly fulfilling, watching notjust my brain, but others as well. It is quite hypnotic, actually. What would you recommend as a dessert . Laughs. As the intensity is increased, as the amplitude of the wave gets stronger, that flow pattern will change and it also controls other aspects of that swarm of colour particles, the scale of the particles will change and also the bloom and decay and blur of a lot of those colours as well. So as all these waves are meandering between each other then you get this Movement Type of animation that plays out. With Something Like this we are able to show how easy it is to access things you are interested in, particularly music, but as voice becomes more common and ubiquitous, i think there will be, it will change how we listen and how we interact with the content that we are really interested in. And experience is everything when it comes to music many of us use it as a drug free way to change our mood. And i cant wait for more choices on the menu. That was lj having her brainwaves read more action in her head than mine, it has been said. And thats it for this week, apart from our big announcement, which is tickets for this years click live the show, are now available. This year we are coming to dundee in scotland, and we would love to see you there. So if you would like to see us in the flesh, you can apply for tickets now at bbc. Co. Uk showsandtours. Its happening next month, we cant wait, and as i say, we would love you to be there too. In the meantime, thanks for watching and we will see you soon. Hello there. Saturday was a day of contrast. We finally got some much needed sunshine across central and southern england and, in fact, in hampshire, we had over seven hours of sunshine. Thats not bad for this time of year. It was a different story though further north, across the scottish borders. There was some heavy, persistent rain at times, and some blustery winds and, in fact, edinburgh had 34mm of rain, around an inch and a half of rain, throughout the day. So the radar shows where that rain tended to sit, through much of saturday. It is starting to weaken off now, as the area of kow pressure is drifting into the north sea, and its allowing a northerly flow to start to dominate across the country. So as the showers fade away and the northerly air kicks in, we will start to see those temperatures falling away, so it could be potentially a chilly start to sunday. Particularly in rural parts of scotland and lincolnshire, in south east england, we are going to see low single figures, maybe low enough for some pockets of frost. So we start off on a chilly note. That low pressure sitting out in the north sea could feed a little more cloud along those east coasts and a few scattered showers. So here it could be cold and disappointing, but further south and west, away from the low, we should see the cloud breaking up, the sunshine coming through and highs peaking at 9 111 degrees. So thats the story on sunday. Just need to draw your attention to whats happening across the near continent. This frontal system may well move towards the essex and kent coast, overnights sunday into monday, and produce some wet weather, but the High Pressure is building in from the atlantic, so that is the dominant force to the weather story on monday, as you can see. Largely fine and dry but we will need to keep a close eye on events down into the south east. That could be a little bit of a fly in the ointment. Generally speaking though, highs are likely to peek, again, at 9 111 degrees. Now, as we move out of monday into tuesday, that area of High Pressure pushing in from the atlantic willjust slip its way steadily southwards, and thats going to allow weather fronts to topple across the high and push into the far north west. So potentially bringing the risk of some more wet weather and certain windy weather at times as well. So only up into the far north of scotland potentially on tuesday. Elsewhere, with a south westerly feed, might be a little more cloud along west facing coasts, but a little bit milder with it as well. You can see the theme is generally a dry one across the country, with highs of 11 15 celsius. So as we you move out of tuesday into wednesday and thursday, its a similar feel to things. We keep the potential for some wetter weather up into the far north. Much of england and wales stay dry and a little milder. Take care. This is bbc world news, im james reynolds.
