Those were our headlines. Now on bbc news click. This week healing without hospitals. Building an e bike. And would you trust an alto keep you fit . That looks exhausting. Welcome to click, hope you are doing 0k. Last week lara ventured into her garden. This week we have both been let loose into the outside world. How was it for you . Oh, it was great i have been on an electric bike and i managed to not fall off, unlike last time. How was it for you . I have to say, i really enjoyed filming out and about again. We have both done this bike then, which you will see later in the programme. One other thing i have done this week is i have been to a comedy gig online, which was really funny. Good thing is that the front row of the audience, if you like, had their mics live throughout so you could hear some of the laughter, which really helped, and i really enjoyed it. That sounds great, and who would want to be on the front row of a comedy gig normally . No, not me. Anyway, as we start to move toward some sort of sense of normality, one of the things that was delayed during lockdown was non emergency surgery. In england, the nhs had to free up 12,000 beds for covid i9 patients. And that meant the delay of 2 million operations. It means that people are waiting to get surgeries like joint replacements, and have been left in pain, and the nhs itself has been left with a huge backlog of surgeries that could reach ten million by christmas. So how is that going to happen and what can people do while they are waiting . Here is jen copestake. Trying to be the fittest old age pensioner in the country. 80 year old brian lewis has been waiting for a hip replacement in his home near manchester since the lockdown began. Like millions of others, brian was on the list for elective surgery before coronavirus, but since march everything is on hold. He could cope with the pain for a few months and has been doing zoom calls with his physiotherapist, but is now finding it very difficult. This side here has completely gone from here to there, the pain has just been in the hip and now it is the whole leg. I have these big muscles in my leg that i cant move. I have always been a very fit guy, you know, but. This excruciating pain. And i have reached the stage now where deterioration has been so great and the last three weeks ive been put onto a stick. Doctors around the country are looking at ways they can remotely assist the thousands of patients that are waiting forjoint surgeries. This includes the creation of new apps and tools that can monitor them in new and detailed ways. Welcome to our lab. Whoever you are, wherever you are. This free app provides free access to some of the Orthopaedic Services a person could expect to have in person. Downloading this app is a great way to recover from your surgery. Great first step. It is part of a service that allows surgeons to monitor their patients at home. The coronavirus pandemic has accelerated the teams work to design more advanced ways to generate useful patient data for doctors. These are infrared cameras, and they are all tracking, triangulating off of these dots. So these are typically used in the computer Game Industry or the film industry. Using datasets from analysis labs around the world, they are training algorithms on millions of data points to create a new camera system that could one day be used with a simple Smartphone Camera connected to the internet. This could recreate the sophistication of a fully fledged Gait Analysis Lab in anyones pocket, and enable a surgeon the ability to confidently assess a range of motion in the patients knee, post surgery, without anyone having to leave home. To create the algorithm it has to be on someones phone, it has to be small and unique and quick, but to make that algorithm we have had to process a lot of data over a lot of years. Because of the vast amounts of training the algorithm has gone through, it can accurately identify the anatomy and range of movement to a degree similar to wearing a morph suit in an expensive gait lab. We are particularly interested in human motion capture, so we have taken lots of inspiration from the gaming world. What we are doing is a very accurate version of this, using Artificial Intelligence to accurately measure joint function. So for a surgeon, can this technology through a Smartphone Camera tell a surgeon if that patients leg is straight after surgery . One of the hospitals advocating the use of these tools is in wrightington. Birthplace of the modern hip replacement, the team here want to see more daycare surgeries to shorten the time people spend in hospital and help clear the backlog. There is an app in development, a specific version to support there is an app in development, a specific version of the myrecovery app to support the day case patients. You can get a lot of information just by talking. But in some cases you have to have a lot of examination, some system to be able to measure the range of movement of a joint, accurately, which would be of benefit. Artificial intelligence could be used in other ways to clear the backlog of cases. C2 ai, an approved user of the nhs dataset is offering a system of triaging surgiers, aiming to prioritise patients based on their operative risk in order to rank them in order of priority. They have identified 14 key variables that correlate with the risk of mortality and will be able to look at the whole countrys surgical backlog at once. We have a version of this where we can upload the full elective surgical list in one, so we can see everybody against everybody. If youre a patient, how would people react to Something Like this . Would some people feel neglected if it ai is doing this . People would want to know there is a logic to it. If they are waiting behind people, it is because they have a greater need. Rather than being done in an inefficient manner, it is being done with a reason. There are large numbers of people on the list, records of their comorbidities, other problems which might mean they are higher risk. Artificial intelligence could be used to scan all that data and come up with a list of patients that fit a certain category, a certain priority, rather than, you know, clerks having to go through that or clinicians having to go through all that data to try and prioritise patients. I think the algorithm could be more sensitive and useful than somebody, sensible. Because they will use the pain thing, one to ten, the Old Fashioned thing. Whereas the algorithm can take so many other things into account that a human being cant take into account. Brian and millions of other patients who signed up to elective surgery still have months to wait. But using patient data and powerful computing systems can help the process and get them in and out of the hospital faster. Hello and welcome to the week in tech. This was the week in which a ag internet Balloon Service from googles Sister Company lune was finally launched in kenya. It was announced two years ago and has been fast tracked now to keep people connected during the pandemic. Facebook was heavily criticised in its own civil rights audit. The report called on facebook to do more to tackle organised hate against minorities and religious groups. The social network said it would make some but not all of the changes recommended. A new video codec was revealed that could put an end to. Well, this, basically. Companies including apple, microsoft and huawei have worked on the h. 266 codec, which uses half as much data per video as its predecessor, so you can record twice as many videos before your phone gets full. If you have had enough of video calls, meetings and catchups and pub quizzes. Theres a new way to get together in microsoft teams, together mode cuts everybody out of their video and put them in a virtual room. Microsoft says it makes video calls feel more natural. Light up drones have been used to promote social distancing in south korea. 300 drones were used in this display above seoul, which reminded people to wear a mask, wash their hands and included message of thanks to key workers. It wasnt advertised in advance, to avoid drawing a big crowd. Here in the uk, things are opening up. But were still being told to only get public transport when its essential. And thats led to a surge in sales of e bikes. The leap has been unprecedented. In may, as an example, we sold more bikes than we did in the entire year in 2018. A decent e bike can easily cost well over £1,000. And there are hundreds of brands to choose from. But the vast majority of them run on tech from just one manufacturer. The number of bosch powered electric bikes in the uk would be somewhere between 60 80 . But the big difference between e bikes is how theyre powered. Some have hub drive motors which track your pedal rotations and power the wheels. Today though im using an even smarter crank drive bike. This uses a Torque Sensor to respond to how hard i press the pedals, and this monster of a battery means it can ride up to 100 miles, not that i am planning on going that far. I have got my high vis, i have my hat and i have my bike, lets go. Oh, wow, i can feel the power. This suddenly feels so light, i cant believe i am going uphill. Hitting 15. 5mph, thats the legal speed limit for e bikes in the uk, was pretty effortless, too. Some countries do have higher speed limits for pedal assist bikes, but if youve seen cyclists putting in zero legwork at all, theyre likely to be using a throttle system. These are less common and in most eu countries you need special registration and insurance to ride them legally. I was excited about the fact that this could go fast, but i didnt think i would have the confidence to do it. Actually, once i got going, the weight of it made me feel so much more confident. Why did they have to speed limit it . But all this comes a price tag. £4,706. It is shocking, really. But spencer has been looking at a far cheaper solution. You might like the idea of a e bike but you may only have a perfectly nice bike already, thank you very much. The good news is you can retrofit your bike to make it electric using a conversion kit like this. Switch is a new front wheel with a 250 watt motor in the middle. It also comes with a power pack and a pedal sensor. This isnt cheap, but it is cheaper than our e bike, and the price you pay is also your time, which will be dependent on how confident you are at taking off wheels, tyres and brake discs. If you think you are going to get stuck then you can pre book a support video call. Obviously, i only called them to demonstrate the service, and not because im a completely clueless dingbat. Switch say they will make these kits to fit any size of bike, basically you discuss with them what you need and they will build the wheel to order. And there is a special adaptor for a folding bike like this one. It is a bit fiddly, but to be honest, i did find it perfectly manageable, and thats saying something because its me attire and a new will. Have tire and a new wheel. Top e bikes use a crank driven system. This is a hub driven system. This magnetic sensor monitors how fast the pedals are going around and then it takes that into account along with things like acceleration to try and work out how much power to deliver. Its not quite as seamless an experience, but is a lot cheaper and a lot lighter. But you do have to accept that they will be some extra cables on your frame after this, and a power pack attached to the handlebars. But assuming that wont upset your chi or your aerodynamics too much, you switch it on, select your power assist level and youre ready to go. First pleasant surprise, it wasnt a complete disaster. And being a total novice i did expect it to be harder to fit than it was. Secondly, it is outrageously fast. I cant actually have it on the highest setting, not on the flats, its just too fast. I hardly touched the pedals and im away. The only thing is that the power assistance doesnt always behave itself. Sometimes cutting out when i need it, and sometimes kicking in when im not even pedalling. Switch say the problem is most likely the pedal sensor not being perfectly aligned, and in fact a new design of sensor is going to be available in a few weeks. If you do want to return your bike to a normal, non electric, you can take the powerpack off, which will leave it only about one kilogram heavier than it was before. Although, i think thats enough exercise for one lockdown, dont you . Wheee great stuff you tested pre made e bikes before, how did this compare . I have to be honest, i know it is the more expensive option but i do prefer the system that looks at how hard you are pedalling and applies power accordingly, rather than the system which looks at how fast your pedal are growing around and having a guess, albeit a good guess at how much power to apply. The system is cheaper, so, you know, it is your money, take your choice. And the spending may not stop atjust the bike. Before lockdown Simon Hancock put to the test some of the latest cycling gadgets. With public transport, shall we say, not as attractive as it used to be, the bike has become the favoured way for a whole new wave of cyclists to get around town. But be you first timer, or old timer, safety will remain a major worry. Surprise surprise, our old Friend Technology has a few gadgets which claim to help. Take this, garmins varia bike light its half light, half radar. Its a really simple idea, you have your phone or your bike computer strapped to your handlebars like this, and the radar here, as a car approaches behind you, gives you a visual and audio indication that its doing so. Now, the question may be whether or not that is a good substitute for listening with your ears, but its an extra bit of awareness as to what is going on around you. But you might also, when you are buying one of these, want to take into account that it cost £170. Some much needed reassurance or a classic bit of tech overdesign . You decide. Its notjust bike lights that are going smart of course. There are also smart helmets or smart airbags as the hovding likes to describe itself. Put it over your head, zip it up and then activate it. And now, as im cycling along, if i have an accident and fall off, it will sense that and it will inflate to protect my head. Weve had this on the programme a few times before but this is the latest generation and comes with an app of course it does. Well be able to collect data off the life of everyday cyclists in the tens of thousands of hours and provide that to cities around the world who are looking for ways to improve the safety of cyclists in their city. Cycling accessories getting connected is a big trend and bringing them all online opens up some interesting possibilities. This is the see. Sense light it came out of a Kickstarter Campaign and what sets it apart from a standard light is that its smart. The light uses an accelerometer to monitor the environment up to 800 times a second. The type of data we are bringing into that analysis is things like the condition of the road, the orientation of other cyclists, the cadence, the speed, the breaking. What this means is that the lights do some clever things while youre cycling. 0n the front light, as youre going around a corner, they seem to flash at a different speed. And with the back light, as you slow down, it acts more like a brake light than a traditional bike light. If you pair the light with a phone, the user gets some extra features. If you have got one on your bike and you go and get a coffee somewhere and leave your bike outside and someone tries to make off with it. You get an instant alert with your phone, which can be quite useful. In exchange, your cycling data is uploaded to the cloud so see. Sense can analyse how people are cycling. 0ne place that has been experimenting with this is the city of london. There are some really interesting examples that have come out of this already. 0ne tells us which bridges people are using, where this data is showing for example, on London Bridge compared to suffolk bridge, the User Experience may be less good because on suffolk bridge there is a better cycling experience in terms of braking and less swerving which could indicate a propensity for accidents. Data helps politicians justify logical decisions because they can show that they are logical and it helps planners make decisions. If you measure where cyclists go now using see. Sense lights or apps or watches, whatever it is they use, they are measuring what they are doing now so you cant go, well, thats where they want to go so ill build infrastructure that protects people who go there. They might be going there because the place they want to go is a two lane motorway and they just cant. A careful interpretation of the data is as critical as gathering it. The humble bike light then has turned bike accessory makers first into Tech Companies and now into data analysts. All cyclists will care about is that some of this will now genuinely help make the streets of our cities safer to ride. That was simon. It might be that you cant get on a bike where you are, maybe youre just not ready to get out and about yet. But you can still get fit on an exercise bike and lara can help you. The things i do for this programme. I have been doing some high intensity interval training, a spot of hiit. Are you into that, spencer . This is when you do incredibly short bursts of insanely intense exercise. Its horrible. It does get the exercise over with quicker though. Then you collapse . Hopefully not. Ive been testing an ai bike called car. 0. L that is based on the concept of doing two sets of 20 seconds going at full intensity amidst an eight minute gentler cycle will give you the benefits of a 45 minute run. No sweating needed. It replicates what is known as laboratory hiit high intensity interval training that would usually be carried out in a lab with scientists. They will be able to look at your data and understand your fat muscle balance creating a personalised formula and the resistance that you need. Here, the ai becomes the scientist. A few setup rides evaluating your physiology before optimising the workout for you. Its not about how long you spend exercising, its not about volume, how much you sweat is not linked to effectiveness. The way exercise works is what it does to you at a molecular level. It is hard to keep going as hard as you can for the 20 seconds. As soon as its over, its really easy again, it feels like it was absolutely pathetic. What youre trying to achieve is something called rapid glycogen depletion. And that only happens when you hit your maximum power that you are literally capable of. We will know if you hit super maximum or not based on the amount of time you have held your peak power for. Its impossible to hold it for more than a fraction of a second. I am no scientist so all i can do is tell you how i felt. And even though i am sure my heart rate has been pushed to the right limits, i was certainly going as hard as i could for those 20 second bursts. I still didnt feel like i had done a workout afterwards. So each time i did this, i went for a good run after. Ok, so this didnt fulfil my workout desires but there is some science to the 20 second bursts. You only have to look at world athletics records to back up the idea that the bodys ability to maintain maximum power deteriorates after the first 20 seconds of pushing to the limit. No matter who you are. The average pace maintained for 100 and 200 metres cannot be continued for sprints that are longer than 20 seconds. So for car. 0. L, this means that the user is going to do the bits that they will work the hardest at and get the greatest benefit from, and the rest is pretty easy. Even if you only repeated it say, four to six times, over the course of a couple of weeks, you can see improvements in fitness that are kind of equivalent to what you would get with much longer, typical endurance, continuous training. It tends to have a clearer effect on the heart and circulation system. As an example, this wont help you lose weight. Weight loss with exercise is about energy expenditure. Wow, i have found a whole other side to car. 0. L. 60, 8 second sprints in 20 minutes and i have never worked out like it. Ok, lets do this speed up, sprint the only thing that did disappoint me a little bit though was that the ai works based on your last workout rather than in real time. If youre feeling a bit tired, its not really going to respond to that. I cant deny being pushed to my limits though, and in the longer term, the aim is for the al to be able to react better in the moment, maybe telling you just by holding onto the handlebars that youre too tired today. I guess we can only hope. Do you need much more . We just need a few more shots, lara. Can you pedal full pelt again . Stop it, i have been working so hard on that bike for weeks the things you do, like you say. That is it for this week. Ifeel like i need a lie down after watching that. You need a lie down . You can keep track of the team throughout the week on facebook, youtube, instagram and twitter at bbc click. Thanks for watching and we will see you soon. Buh bye it isa it is a fine day for most of us but for some of us the sunshine was this morning and what comes after that cloud and rain, similar picture in western scotland before the end of the day as well because low pressure is quite a long way as well you will find the centre of that but weather fronts trailing from that is bringing in the cloud in the rain across Northern Ireland and into much of scotland, going deeper onto the evening, whereas for england and wales a dry day, certainly increasingly hazy in places, and much of that night dry although some outbreaks of rain de pushing towards Northern England and north wales, and it is a much milder night compared with the last few temperatures. Last night, for example, parts of wales drop down to just one celsius. Tomorrow a much cloudier day across the uk. Northern ireland and scotland seeing some patchy rain around in the morning for many others, though, trying to get a for many others, though, trying to geta name, some for many others, though, trying to get a name, some sunny for many others, though, trying to get a name, some sunny spells around, plough. 0utbreaks get a name, some sunny spells around, plough. Outbreaks of rain across england and wales, not much across england and wales, not much across south east england at all, Late Afternoon and into the evening still 23 celsius but elsewhere it is not cold but were talking high teens are 20 degrees and it will be a breezy day tomorrow. That would have won with cloud and patchy rain continues across south east england overnight and into tuesday, may still have an area of cloud and some patchy rain first thing before that pulls away, what we are left behind thatis pulls away, what we are left behind that is quite a bit of cloud, some sunny spells coming through on tuesday, and a few showers around, perhaps another weather front approaching Northern Ireland, and each i was turning into another speu each i was turning into another spell of persistent rain, especially the further west you are, and it will feel a bit cooler on tuesday as we turn the wind around to more of a north westerly direction. This weather front just pushes north westerly direction. This weather frontjust pushes on through overnight and into wednesday, not a huge amount of rain on it, and behind that for the rest of the week, High Pressure is Building Back in. There will be a loss of cloud, there may be the odd shower, just a few sunny showers but what many of us few sunny showers but what many of us may notice during the second half of the week is this temperature is creeping up a few degrees and for some parts of england in particular approaching the mid 20s later in the week, so for mid week, then, High Pressure building and a lot of dry weather. I think it will become a bit warmer. Hello, good afternoon. The governments announced more than £700 million is to be spent on the uks border systems, as they prepare for the end of the brexit transition period on january 1st next year. It follows a leaked letter from International Trade secretary liz truss raising concerns about the readiness of britains ports. Labour has accused the government of complacency in its post brexit preparations. 0ur Political Correspondent nick eardley reports. Change here, britains border, is coming
