 colleague, John, that is calling from the bay. So we are back to the West Coast with John, and he will talk about flight sense technology that can really enable touchless button. So very, let's say, on time for the difficult period that we are living. So, John, I will turn to you if you are connected and I see you here. Eddo, I am. Thank you very much for introducing me. And I'd like to talk to everyone about the touchless button. This is not a new sensor, but a new application for this sensor. I'm from the SD Imaging Group. Most of us are in Europe, but I'm in California. And with that, we'd like to get started. We have a result. Oh, thank you. About half of you have used the time of flight and the rest of you want to know about it, which is great. And I'll spend a little more time on that slide as we get to it. But let me introduce the topic at the moment. The applications for a touchless button are pretty varied, but it turns out during the day you touch an awful lot of things. You touch vending machines, you touch elevators, you touch parking meter buttons, you touch ATM screens, you touch all kinds of things. And they would be just a little bit better in this age of COVID if you could just come close to the button and not actually physically touch it. We can enable this very easily. It's a sensor that's been around for a while and it's just we proved it works quite well. And I'm going to show you how to do it. The key advantage to a touchless button is that you don't have to touch it. It's obviously very sanitary, but it also when you clean it, you know, one quick swipe of a rag, there is no cracks or crevices. It's completely behind a solid piece of glass. And you can just work acrylic and you can just wipe it down very quickly. It's very reliable. It's all solid state. There's no moving parts. And it's very secure. If you built an ATM out of one of these things, you could hit it with a hammer and still wouldn't be problem. Acrylic is a great material for being vandal proof. And we can strike for that. So how does it work? For those of you who didn't know about it, time of flight, this blue graphic here shows one photon going out of the emitter and hitting a target and coming back. But that's not exactly how we use it. The emitter is a vertical cavity, surface emitting laser. It's a VIXL and it shoots millions of photons out and hits that target. And when the sensors come fly or the photons come flying back, they're captured by a spad, a single photon avalanche diode that has to be pretty much invented. And that stops the stopwatch. Knowing that time, you measure, you take the time, divide it by two and multiply by the speed of light and you get the travel time. You get that answer in millimeters and it's pretty darn accurate. And with that, you can determine when the finger actually comes within a few millimeters or a few inches depending on your application of the button. So what can you do with it? Well, traditionally, these types of things do the G-detect on your phone. It does the autofocus assist on your phone, but you can also use it to turn faucets on and off, open garbage cans, even start a coffee maker if you wanted to. And oddly, there's a picture of a mirror there that the sensor can be used to determine how far your face is and adjust the brightness of the mirror, the light on the mirror, clearly, and to see what's going on. But used in a different application, we can take the STM development kit that we have on our website and determine how to build a touchless button. So I'm going to push a little video here and show you how it works. As you see the, maybe you don't see it. There you go. As you see my hand go up, down, back, forth, you can see how fast it is, switching on, off, and all that works by shooting the photons out, detecting the hand is there, detecting the hand went away, and that's the way it works. In another mode, we can take the same thing and prove it works with dimming. Should you want to do that? As my hand, come on, there we go. Thank you. As my hand comes in and out, watch the numbers go from 99 to 31. See it? And then determine how close my hand was, set in just dimmer adjustment, and then move my hand away. And it also works as an on-off switch. So under the covers, how does it work? The red line in this graph shows 255, the artificial maximum. And as my hand comes closer and closer, you can see the red line drops closer and closer to zero. And then as I take my hand away, it drops back to 255. I took this graph in a bright California sun outside. And as you might well imagine, that's the worst case possible. And the little black line here that you see is the signal strength coming from my hand. What you see are four very quick button presses. In a different graph, this is indoor. This is a lot easier to do. And you can see somewhere around, as on my finger, it's closer, somewhere around 15 or 20 millimeters, you can kind of see where you can actually see the finger getting close. Outdoors, you pretty much say it's close, but much more accurate indoors. And again, four simple button presses. If you are considering a high voltage like a light switch, ST's got a development board. This one will plug underneath the bottom of that setup I just showed you. And it has the ability to control up to three lights. I'm not sure how you'd actually implement that, but that'd be the way to build a mock-up of a light switch. And you could be testing in a matter of hours. All my flight sensors, time of flight sensors can do this. They can do tap detection, double tap detection, swipe direction, level control. Additional features you can do left and right swipes if you use the more advanced VL53L1 or L1CB in a multi-zone scanning mode. And all of them can do different ranges. So basically from the smallest to the largest, you can get distance. And I'm not sure why you'd need a switch that works at four meters, but I suppose you can do it. Gesture recognition is good for music control, IoT functions, hands-free tub Bluetooth on your earphones, and VR glasses were used for that. And it works in all these applications. If you're trying to do a right, left swipe, you can see, maybe you can't see, it's pretty small. But as you can see, my hand swiping back and forth, there's a zone one and a zone two. And these two zones allow you to detect whether the hand was swiped to the right or to the left. If you don't want to use the development board we have out of the imaging group, you can buy a discovery kit available from ST. And it has all the sensors that you want to use in addition to my time of flight, which is that little circle there in the lower left. And with that, perhaps we have some questions. Okay, yes, John, you have been quick and I think the videos work very well. So, you know, this was also the beauty to try videos with a live event. And maybe if I just can add, John, these IoT discovery kit, just correct me if I'm wrong, these provide not all the sensors including time of flight, but basically we are providing also the sensor to cloud connectivity, right? What has been described before, so perfect. So, people can really bring time of flight, the sensor data to the cloud easily thanks to this IoT discovery kit.
