How Embedded Systems Transforms the Healthcare Industry?

Imagine how cumbersome healthcare used to be in the past. Back then, a person not feeling well had to approach a doctor, who then proceeded to prescribe medicines based on his external symptoms. How accurate can the diagnosis be in such cases? The reason why a few decades ago a disease that we take for granted today could kill masses was because the diagnosis wasn’t thorough. Then the technology advanced. We got X-ray, ECG, EEG, MRI, CT, pulse oximeters, GlucoWatches, electronic defibrillators, and a large number of sophisticated gadgets (embedded systems) and acronyms that the general public has no idea about. Now, the technology is even more advanced. New microchips, nanotechnology, and embedded systems have managed to revolutionize the healthcare industry.General Electric – A Premier Provider of Medical Embedded SystemsLook at General Electric, the multi-billion dollar vendor of all kinds of electric systems. GE is the premier provider of medical embedded systems in the world. All kinds of technologies–from scanning machines, imaging systems, and diagnostic equipment–are there in GE’s range. Behind all these advanced systems is embedded technology. Take a look at this image of a huge PET scanner from GE, a perfect example of an embedded system:[Image Source: General Electric]Sensors for NewbornsI was perusing the acme of technology IEEE Spectrum, and I stumbled upon an article that describes what the future has in store for us. In the next few years, newborn babies will get tiny sensors within the first few minutes of their birth. A chip that is planted in the body of the infant continuously monitors its health condition, and the biometric data generated and stored in the cloud by the child through this chip within two years will be more than the entire amount of data created by everyone combined in the world today. In essence, this data can be used by medical professionals to track every aspect of the health of the child.Soon, medical gadgets will turn out to be more glittering and sophisticated than the ones in the books of Ian Fleming. A few days ago, BBC reported of a gadget–a tiny ring–that reports and catalogs a person’s medical conditions. This is a perfect wearable that comes handy in emergency situations as a microchip embedded inside this ring alerts paramedics during an emergency.[Image Source: BBC]Electronic TattoosYou have probably heard already about electronic tattoos that dilate with your skin. These temporary electronic tattoos are powered by solar energy and replace those bulky gadgets, such as a pacemaker, to monitor the health conditions of individuals. Since the material used is stretchable, sturdy, and highly flexible, you will not even know you are wearing a health monitor.When it comes to advanced robotics for intricate surgical procedures, check out the da Vinci Surgical System, manufactured by Intuitive Surgical, Inc. This is the only robotic surgery system with approval from the US Food and Drug Administration (FDA).But now, a team of geeks from University of California, Santa Cruz and the University of Washington have successfully created a set of seven robotic surgery systems for use by medical research labs across the US. These systems use open-source approach for software development, cutting the cost of ownership to the bare minimum.When it comes to embedded technology within gadgets, you probably know about a number of technologies. There are real-time operating systems in the embedded world that find applications in military-grade equipment.Examples like QNX (acquired by BlackBerry), OSE, VxWorks, ucLinux, and LynxOS come into mind.From small embedded systems that monitor the heart rate or identifies a blockage in an artery, the technology seeped into intricate surgical procedures. It is quite possible that in the future you can own your own robot doctor, with or without remote assistance from a real one. As the functionality of embedded systems in use in healthcare increases, one thing that decreases is their size. A recent article in Discover suggests a possible device–a “microbot”–about a decade from now that can be inserted into your body by making a tiny surgical incision. The microbot can travel through your blood vessel and reach the area of concern. It can fix minor issues, such as blockage in an artery, and collect tissue specimens for testing. A tiny camera attached to this device can send high-definition images and videos to the doctor about what is happening in your body. The futuristic microbot can be powered by a tiny motor about the width of two human hairs.ConclusionAs you can see, medical technology has advanced quite a bit with the help of embedded technologies. Stretching the limits of the Moor’s law, semiconductors, processors, and chips are going down in size in an exponential fashion, while the number of transistors in each chip is growing by leaps and bounds. SoCs, embedded operating systems, and software that power these devices undergo some serious R&D. Aziro (formerly MSys Technologies) also has quite a bit of experience in embedded technologies and real-time OS (RTOS) making us a perfect innovator for the technology of tomorrow.

Internet of Things: What the Future Has in Store!

Imagine your washing machine calling on your smartphone and telling you in a Siri-like voice that it’s time to wash your socks. Imagine you receiving texts on your phone about your garage door being left open, your car out of fuel, or your toaster finishing its work. In the near future, this may no longer be science fiction; it is very much possible that any object you have in your home will start talking to you–in fact, not only to you but to any other objects around. What enables this is a technology known as Internet of Things (IoT).What is this revolutionary new technology? What is Internet of Things? This term has existed and been hackneyed since the early ’90s so as to breach the boarders of cliché. People have come forward with certain other terms to substitute “Internet of Things,” but most of them turned out to be just bush-league. Internet of Things refers to a future in which your commonplace objects—things that you normally do not associate with technology—start to communicate as part of a network. This concept radically augments our idea of the smart planet, because you can communicate to not just computers but every object in your home over the Internet.IoT and the Fascinating FutureIf you are a fan of popular sitcom Big Bang Theory, it has an interesting episode in which the characters light lamps and turn down stereos using their laptops by sending signals across the Internet. After a while, by giving open access, unknown people start playing around with the lamps in their apartment. This kind of development is highly invigorating as well as slightly intimidating for many people.While on one side people are talking about the advantages of IoT, a discussion is looming large on the horizon about the security concerns surrounding the concept. For instance, what if the bad guys hack into your smartphone to disable your home’s security system and open the doors of your house while you are away in Hawaii on a vacation?One area IoT is going to transmogrify is the automotive industry. Already, the cars are as smart as you want them to be. A few days ago, I was watching the Audi keynote in the International CES (watch it below), and wow! The cars can not only park themselves but drive you through busy streets. The technology is that sophisticated now. Last week, Fox News published a piece on V2V (Vehicle to Vehicle) communication system that helps cars communicate with other cars in the vicinity to convey important information, such as whether or not the driver is applying breaks properly to avoid a possible collision.The US department of transportation is considering a regulatory proposal for vehicle to vehicle communication. You can go to BBC Top Gear and be literally flabbergasted at the automotive technology that is emerging. In essence, cars have advanced through technology in the last decade more than they ever did in a century led by mechanical engineering. Embedded computing technology is at the helm of all these developments.When IoT comes to our world, these cars will be well connected, through 4G technology. They will communicate fluently to bring assistance to you wherever you are.Cisco has done quite a bit of research on Internet of Things (which they call Internet of Everything in their vernacular). Check out that site; it’s a goldmine of information on IoT. According to Cisco’s findings, released in Feb 2013, IoT globally will be worth 14.4 trillion dollars in the next decade. I happened to look at the data concerning our country too, and the value at stake seems to hover around 35 billion USD. When it comes to the zenith of information technology, the United States, the total value at stake seems to be 473 billion dollars.IoT: How It Changes Your World?I have given you a slight idea of how IoT is going to change your future in the beginning of the article. While some of the ideas may be a bit out there, there is virtually no bounds to the way applications can be developed to incorporate things. Embedded systems will be subsumed into almost every object to make it more intelligent. That’s where the washing machine that talks and texts comes in. These developments can significantly improve your lifestyle.Just as the lot of geeks in the Big Bang Theory, IoT will exhilarate the techies amongst us. They will come up with specialized applications that do everything from garage-door-opening to toilet-seat-lifting. The way IoT can uplift the services in certain industries today is bound only by your imagination. Surveillance, security, healthcare, education, retail, etc., are some of the industries that will taste the massive benefits of Internet of Things.There is a minor problem. And that concerns software development. For an analogy, consider today’s mobile app development. While a developer needs to concentrate on only one device (or two) in case of iOS development, he has to consider a plethora of hardware configurations, resolutions, processors, and OS versions when it comes to Android. Imagine if a developer needs to create an app that controls refrigerators or washing machines? There is more diversity there than the number of verses in the King James Bible, figuratively speaking.This development intricacy has also been discussed by a recent podcast in GigaOM. They also discuss the rampant privacy concerns surrounding the subject. Play the podcast to listen:How IoT redefines our world is well illustrated in this image:As a first step of inventorying everything to be managed better, you can use technologies such as RFID (Radio-frequency ID) and NFC to tag each object. Then, they can be managed through a network, and locating and securing the inventoried objects become a piece of cake.There is, however, one little issue concerning IoT: the standardization. We should come up with a way to standardize the tagging technologies that we use—RFID, NFC, barcodes, or QR codes. It should not be as wayward as in the case of 4K resolutions (wherein there are six different resolutions and no fixed standard).In essence, for coherence and congruence, everything from development to nomenclature should follow a standard.How far are we in realizing IoT in our cities? Well, when it comes to Ubiquitous Cities (aka smart city, wherein everything is connected with computers), Songdo IBD of South Korea is probably the first. It is a smart city where everything is connected, not just computers.ConclusionI could go rambling on and on about IoT as it is quite an interesting topic. Aziro (formerly MSys Technologies)’s development teams have expertise in embedded computing technologies, which is right there at the brink of IoT. It is inspiring to know that we are part of a global team working toward the future of technology.
