You didn’t know that you could prevent chronic diseases like heart failure, obesity and stroke using the Internet. With tech and healthcare you can.
“Prevention is better than cure.” That’s why we’re encouraged to eat more vegetables than meats, exercise, more than sit, and sleep more than play videogames.
But do these things really help? How would we know for sure that we’re actually becoming healthier with the lifestyle changes we’re making, and not staying the same, or even getting worse?
Juliett Starrett is a CrossFit athlete and the co-founder of San Francisco CrossFit. After giving birth and receiving a blood transfusion, Starrett kept feeling fatigued and getting chronic headaches.
The doctors put her on antibiotics, and thought it was just temporary. But even though Starrett was both extremely health-conscious and fit, she didn’t get better. To help her get through the day, Starrett resorted to drinking eight cups of coffee a day.
Starrett started working with WellnessFX. WellnessFX is a webbased service that combines traditional blood tests with intuitive online data tracking and phone consultations with physicians. Using WellnessFX, Starrett discovered that her iron, vitamin B12 and D levels — indicators of physical energy — were extremely low.
Thanks to WellnessFX’s ability to track biomarkers over time, Starrett changed her lifestyle, diet and supplements to attack her deficiencies. Over the next few months, her energy levels improved significantly, and she could cut her coffee down to a cup a day.
Not only did she feel better, Starrett could actually measure her improvements, using WellnessFX’s regular blood tests and online data tracking, to quantify how her biomarkers changed over time.
Tracking your biomarkers over time isn’t just something for elite athletes — according to the Center for Disease Control and Prevention (CDC) in the United States, chronic diseases and conditions, such as heart disease, obesity and arthritis, are among the most common, and preventable of all health problems.
By monitoring your blood over time, you can track and stop markers like cholesterol, inflammation and blood sugar before they hit unhealthy levels.
Internet-connected health services aren’t just good for preventive care. In 2014, the University of California, San Francisco, began offering patients the use of a miniature wireless device called the CardioMEMS HF System implant.
The CardioMEMS is a battery-free device that’s smaller than a coin. It monitors the patient’s heart rates and artery pressures, and transmits them in real time to the hospital. Not only does it help doctors measure how patients are responding to different treatment therapies, it can tell doctors that a patient’s heart condition is getting worse, even before the patient feels any symptoms.
While having your personal health data online can be convenient, and in some cases, life saving, the one major concern is how secure and private your data can remain once it’s shared. The University of California, Los Angeles (UCLA) Health recently experienced a cyberattack, which may have compromised as many as 4.5 million patient records.
But online healthcare might be a case where the potential rewards will far outweigh the risk — the stakes are as high asthey can ever be when lives are at stake.
Today, there’s a lot of talk about bringing our everyday appliances online, a concept that’s commonly called the Internet of Things; Internet-connected refrigerators and washing machines are real products you can go out and buy right now.
The logical extension of that is surely when our bodies join the Internet of Things. With services like WellnessFX, devices like the CardioMEMS, and consumer wearables becoming more adept at tracking our everyday activity.
The activity tracker you have on your wrist can do more than just count the number of steps you have taken and the hours you have slept. It has the power to change the way medical research is conducted.
MEDICAL RESEARCH IS A PARAMOUNT COMPONENT of medical studies and is crucial to our understanding to how people react to symptoms, how diseases work, and how effective a particular drug is in the real world.
One of the biggest challenges facing medical researchers is the lack of subjects. The truth is that methods for conducting medical research haven’t really changed in decades. Researchers would try to recruit subjects by putting up flyers, or attract them by offering small rewards for participation. In some cases, university might even make it compulsory for undergraduates to participate. Needless to say, these methods do not provide an accurate a cross-section of the population, thereby limiting our understanding of diseases.
Apple wants to change this. There are already hundreds of millions of iPhones out there and millions of users wearing Apple Watches and other activity trackers. So how can they harness this? The answer is ResearchKit, an opensource software framework that will allow researchers and developers to create apps for medical research.
n a nutshell, ResearchKit will allow researchers and doctors to gather more data by using apps and taking advantage of the millions of iPhones and Apple Watches that are already out there.
For example, one common way to assess Parkinson’s disease is the Parkinson’s Gait Test, where a doctor rates a patient on his walk on a scale of 0 to 4. It’s highly subjective and also troublesome to conduct as it requires patients or subjects to come in and walk in front of a doctor. But by using the accelerometer in the iPhone and Apple Watch, ResearchKit lets researchers and developers create apps that can accurately measure the gait of a patient or subject. It also lets subject do the test wherever they are and whenever they want.
Beyond Parkinson’s disease, ResearchKit will also allow for other apps to be created that can be used to measure and test for other conditions and diseases, allowing research subjects and patients to self-diagnose and take part in research without traveling to a clinic and without the presence and guidance of doctor. It makes things much more convenient and simpler.
Since ResearchKit pulls data out of the Health app, it’s not limited to just the Apple Watch, it will work with any wearable that uses an app that syncs with Apple Health – and that’s a list that includes popular wearables like Jawbone’s Up activity trackers, Withings Activité smartwatches and Polar’s running watches and activity trackers. This allows researchers to gather a larger, more diverse and meaningful amount of data.
Beyond Apple and ResearchKit, Google also wants to use wearables to advance medical research and studies. In June earlier this year, Google’s Google X research division announced a wristband that was
designed specifically for medical research. It will be more accurate than consumer grade activity trackers and it can measure heart rate, heart rhythm, skin temperature and even ambient light exposure and noise levels by the minute.
The intended use of this wristband is for doctors to prescribe them to patients or for use in clinical trials. in future, devices like Google’s wristband will be given to everyone, so that doctors can be alerted to problems and people can catch signs of diseases early.
Like Apple with ResearchKit, Google is hoping that its new wristband will let doctors track their patients more accurately and reliably, especially when they are away from hospital, thereby giving them deeper insights into their conditions and their lives, and also alerting them to any major complications before they can occur.

With a seemingly countless number of connected devices, the Internet of Things (IoT) will be a gigantic growth market in the coming years. With the right solution, developers can concentrate on their core competencies and access the required specialist know-how in the shape of affordable, reliable and pre-validated modules.
The Internet of Things is growing steadily and rapidly. These intelligent objects have their own IP address and are constantly connected to each other over the internet, making them able to communicate freely with each other. Sensitive data and devices must be protected from unauthorised access.
The first requirement for a network of machines and devices of any kind is secure IoT access. This can be provided either directly or via a gateway. In the first case, a gateway will already be implemented in the individual device. A protocol conversion between the internal and external network is often useful and necessary. Security is a complex issue and involves safety’ (broadly referring to safe operation) and ‘security’ (meaning safe from attacks by outsiders).
Intel quickly realised that this is a major obstacle for widespread access to the IoT. In cooperation with its subsidiaries Wind River and McAfee, Intel set out to develop a secure end-to-end solution available from one source. This seamless and secure solution combines the individual products and special expertise from each company for selected platforms such as the Intel Atom-38xx family. Wind River supplies the Wind River Intelligent Device Platform XT which includes the operating system (Wind River Linux5.0), prevalidated software stacks, hardware drivers and matching libraries and tools. Functions such as administration, communication, connectivity and security as well as runtime environments such as Java, Lua and OSGi are all supported.
Fig 1 congatec’s current offering on the hardware and software sides of the IOT topology, with the Intel
processor selection on the left, and the matching form factors on the right.
McAfee’s security software, McAfee Embedded Control, provides features such as dynamic application whitelisting (only registered and verified applications can run) and change control (all modifications of the code and the environment must be explicitly approved before execution). Intel provides the hardware platform itself plus hardware feature enhancements such as TPM (tamper proof module) and matching hardware-related software and stacks. The essential point here is that Intel validates the end solution as a whole; the complete processor board including all firmware.
For those who neither want to rely on finished, commercially available devices nor go through the complicated and time-consuming process of certifying their own developments with Intel, the use of pre-certified function blocks makes good sense. Many industry sectors already use modular computer systems that are highly scalable for the specific application and based on proven standards such as Qseven or COM Express. The use of modules that are precertified for the Intel solution not only saves time and cost when implementing secure Internet connectivity, they also open up all the advantages of modular computer systems. Important criteria when selecting a module supplier includes support of the relevant standards, quality of the modules and the ability of the module manufacturer to effectively support the system manufacturer in the development of its own systems.
The the conga-QA3 Qseven module from congatec with processors from the Intel Atom E3800 family is particularly well suited for connecting to the Intel Gateway Solutions for the Internet of Things. It enables the use of Intel Atom processors with up to four cores and clock speeds from 1.33 to 1.91GHz. Depending on the system and its application, the total power consumption ranges between as little as 4.5W to 12W. This enables the development of very economical and extremely powerful embedded PCs, that can be hermetically sealed and operate fan lessly in an extended temperature range. The maximum RAM size is 8GB DDR3L memory, and the integrated Intel HD graphics can support two independent Full HD displays via DisplayPort, HDMI or LVDS. Numerous interfaces and functions (including Gigabit Ethernet and USB3.0), enable fast and cost effective realisation of high-performance embedded systems with low power consumption such as Box PCs or other customised solutions.

The combination of reliable hardware and a consistent software package, including everything from firmware to operating system and applications, provides a totally secure root of trust for IoT gateway applications. Thanks to outstanding performance, it is possible to carry out additional demanding tasks such as evaluation, consolidation, storage and visualisation of data, as well as sophisticated protocol conversions between the individual connection levels.
QSys is a modular embedded PC from TQSystems based on the Intel Atom E38xx. The combination of the MB-Q7-2 mainboard and thecongatec conga-QA3 module provides a highly compact embedded computer system and an ideal platform for use with the Intel Gateway Solutions for the Internet of Things.
The compact box design, with external dimensions of only 100x100x23mm³ and many interfaces and functions, is an example of how to quickly and cost-effectively implement a high-performance, passively cooled embedded system for gateway applications. Hardware security features such as TPM 1.2/2.0, the Sentinel HL Security Controller and integrated secure EEPROM enable the realisation of embedded systems with an exceptional level of security. The example has shown how quick and easy it is with congatec’s modular system to build concrete solutions for secure IoT gateways. The right know-how and technology can, however, bring further benefits. Thanks to the 70x70mm compact form factor of the Qseven module it is easy to transfer the system layout to a customised system, making the development of complete single board computer systems a simple and inexpensive task. The re-validation effort is relatively low because key components, such as processor, I/O system, network peripherals and firmware, require no or little modification. congatec has, for example, already implemented a complete mini- ITX single board solution.
As an ODM (Original Device Manufacturer) congatec can also develop complete customised systems and validate them for the customer, or use its know-how to help customers validate their own developments. The cost optimisation of this approach is particularly interesting where large production runs are concerned.
Modular systems consisting of pre-integrated hardware and software modules enable manufacturers of IoT-enabled systems to develop secure solutions quickly and costeffectively, without having to deal in any detail with the complex security issues. On the one hand, security is safeguarded by a global player such as Intel bundling its expertise with that of its subsidiaries Wind River and McAfee in an end-toend, validated solution. On the other hand, they can rely on the manufacturer of the appropriate certified standard module, who is responsible for high manufacturing quality and practical support during the implementation of the complete solution. It is important to select the manufacturer carefully to avoid unwelcome surprises later on.
While current modules are primarily designed to provide gateway functionality for applications in the areas of industrial electronics, mechanical engineering, energy supply and transportation, subsequent modules and validation packages will cover additional functionalities and industry segments. The possibilities offered by the IoT are virtually unlimited and hold a rich potential for further development
The estimates of how many connected devices will constitute the Smart Home market are all over the map. This sector is going to be big and will be extremely important to the future of the electronics industry
Smart Home: let us define the Smart Home as being a network of Sentrollers – sensors, controllers and actuators, connected to a central home control box and from there to an intelligent dashboard in the cloud that can be monitored and controlled by web connected devices like smart phones.
Currently, there are 600m connected homes in the world- connected homes have some kind of internet connection. Of these, on the average, each has about ten connected wifi devices. This includes computers, laptops, phones, games, entertainment systems etc.
As the number of connected homes grows, there will be an increasing movement to incorporate sentrollers into the home. Whereas there are about 10 WiFi devices in the home today, within
ten years, we expect to see about 100 or more sentroller devices within each home.
This will include a network of different kinds of sensors spread throughout the home- temperature, motion, position, security, humidity, etc. that will track the life activity of those in the home. This includes position sensors for measuring whether a door or window is open or closed, motion sensors that track where in the house a certain occupant may be, temperature sensors to ensure that the house is at the proper temperature, while at the same time ensuring optimal use of energy (i.e. not heating or cooling the house when nobody is home. This can also include humidity sensors adjacent to plumbing fixtures to provide alerts in case of leaks.
Intelligence can enable many of these sensors to provide dual uses, i.e. when no one is in the home and the security system is on, a motion sensors can send an alarm, if it detects someone moving around. However, when the However, when the residents are home, the motion sensors can turn on lights to illuminate a path during the night or customise temperature for the room in which the person is in. The motion sensor could even activate the appropriate music selections to follow the person as they move from room to room.
Depending on their function, these sensors can communicate among themselves and to a central home control unit, which connects all the home’s systems to the internet and allows control and monitoring of the home via cloud intelligence, smart phones, tablets or other web connected devices.
Within the homes however, the devices need to talk to each other and to the central home router/network. There are a variety of wireless technology standards that can be used to tie together these sentrollers and make sure that they can reach the home control box (i.e. the router).
We believe that there will be three open standard based networks within the home. For example, WiFi – with its wide bandwidth (and power hungry) requirements, will be used for big data applications, like video streaming, music, phones, gaming, etc. In contrast, Bluetooth will be used for short range communications between low data rate devices like wearables and medical health (heart rate monitoring, fitness band). However, for most sensor applications in the home, IEEE 802.15.4 based protocols like
ZigBee will be the most suitable.
Operating in the 2.4GHz frequency range, able to transmit through walls, floors and furniture, and cover an entire house, IEEE 802.15.4 based wireless offers an ideal convergence of robustness, bandwidth, power requirement and cost.
Designers can essentially consider ZigBee as low data rate, low power WiFi. Most consumers have grown accustomed to charging their portable WiFi devices every day or so. In contrast, no one will want to
regularly change batteries on the hundred or so sensor devices in the Smart Home of the future.
ZigBee offers the ability for a battery powered device to run for up to ten years without having to change or recharge the battery. Because ZigBee only needs to send small data packets on an occasional basis, it
does not require the power used by WiFi which continually transmits millions of data packets.
ZigBee offers various other advantages to the device developer. As an international standard, it enables design engineers the knowledge that their device can be used anywhere in the world, unlike some other non-standard wireless solutions like Zwave and EnOcean. Also, as it is an open international networking standard, there are many different companies offering ZigBee radio chips – this enables manufacturers to multisource the radio chips, not locking them into a single provider.
The new Smart Home – the Intelligent smart home – will be composed of a network of sensors, actuators and controllers – all connected by a reliable, robust and power efficient wireless connectivity standard, provides a path to the next generation, multi trillion dollar electronic component and smart home devices market.
