High school student creates a smart wearable for Parkinson’s patients


OneRing monitors motor distortions and generates patient reports.


After school activities for the average high school student typically entails sports practices, music lessons and homework; but creating a smart medical device for a disease that affects 10 million people seems unlikely. That’s not the case for Cupertino High School sophomore Utkarsh Tandon. Tandon is the founder of OneRing, an intelligent tool for monitoring Parkinson’s disease.

OneRing is a wearable that captures movement data from a patient, algorithmically identifies Parkinson’s tremor patterns and classifies the severity. Tandon first became interested in studying the disease when he watched a video of Muhammad Ali, who has Parkinson’s, light the Olympic torch in 1996. After volunteering at a local Parkinson’s institute, the 15-year-old decided to build a company that focuses on improving the lives of those affected by this movement disorder. He began working on signal processing and machine learning algorithms, before evolving the concept and founded OneRing.

OneRing quantifies Parkinson’s disease movements and its mobile app leverages the data collected to generate smart patient reports that physicians can use to better prescribe medication. At the core of the device is its machine learning technology. The OneRing has been trained to model various Parkinson’s motor patterns such as dyskinesia, bradykinesia and tremors. A Bluetooth module encased inside the 3D-printed plastic ring allows it to communicate with its accompanying iOS app to provide time-stamped analytics about the patient’s movement severity during the day.

The ring itself currently comes in three sizes, each varying in diameter: 18mm, 19mm and 20 mm. Tandon and his team hope to develop a “one-size-fits-all” piece in the near future.

With this Kickstarter campaign, Tandon hopes to deploy OneRing to a local Parkinson’s institute where the device can be used in exams and sent home with patients. Ultimately he wants to bring OneRing to patients all around the world in hopes of suppressing the condition’s rapid progression. Interested in the cause? Head over to the OneRing project page, where Tandon and his team have already doubled their pledged goal of $1,500.

playDXTR is a new smart toy that monitors child development


Building blocks for kids just got cooler and smarter.


If there is one toy that has managed to be a staple in every kid’s play area, it’s probably building blocks. But in today’s screen-based world, digital devices lately have been the focus of playtime. Now, the analog building block just got a tech upgrade for the 21st century kid. PlayDXTR is a set of building blocks with embedded technology that can observe, monitor and quantify a child’s cognitive development.

Blocks1

PlayDXTR comes from the playful imaginations of Rene Lund, Mikkel Moos, Frederik Nielsen and Kenneth Madsen at DXTR Tactile. Their goal is to “bring toys toward the future by leveraging modern technology with good old-fashioned play,” and their latest product does just that.

27 different smart and magnetic blocks, called Kubits, make up playDXTR. With its built-in sensors, each Kubit can communicate with other Kubits by registering motion, direction, orientation and relative connections. An accompanying mobile app prompts children to construct things and arrange blocks in certain ways, which creates a stimulating and imaginative play experience for kids.

As the child plays with the blocks, the movement is monitored and analyzed, subsequently delivering data to parents about their child’s developmental progress. To name a few, parents will receive real-time information on their child’s critical thinking, problem solving, planning, memory, motor skills and attention span. Additionally, playDXTR offers insight to games and activities that can strengthen certain skills. What’s great about playDXTR is that it’s a fun toy for kids and a useful tool for adults.

Block2

Inside the waterproof, shock-resistant casing of the Kubit are RBG LEDs, a Bluetooth Low Energy module and motion sensors. Funds from the project will help the DXTR team assemble the next generation of hardware, which will include a 32-bit microprocessor, a low-power IMU and a rechargeable lithium polymer battery.

Intrigued? Head over to playDXTR’s Kickstarter campaign, where the DXTR Labs crew is seeking $50,000. Delivery is slated for April 2016.

SmartEgg connects all your remotes to your phone


A truly universal and eggscellent remote for the Internet of Things.


It seems like today we have remote controls for everything and keeping track of them can be a hassle. Our current home entertainment systems alone require more than one remote to rev up our TV, cable box, audio system and DVD player. Do we honestly use all the buttons on each of these remotes? Unlikely. The team at AICO Technologies are making things easier for us by replacing all of those remote controls with just one.

mbed eval boards showcase focus on IoT software and connectivity


Chipmakers like Atmel are joining hands with ARM to bring the entire ecosystem under one roof and thus facilitate the creation of standards-based IoT products.


ARM’s mbed operating system is winning attention in the highly fragmented embedded software space by promising a solid software foundation for interoperable hardware and thus scale the Internet of Things designs by narrowing the development time.

Atmel has put its weight behind ARM’s mbed OS by launching the single-chip evaluation board for the IoT ecosystem in a bid to ensure low software dependence for the embedded developers. The leading microcontroller supplier unveiled the mbed evaluation platform at the recent ARM TechCon held in Santa Clara, California.

The mbed OS platform is focused on rapid development of connected devices with an aim to create a serious professional platform to prototype IoT applications. So IoT developers don’t have to look to software guys for help. The mbed stack features a strong focus on enhancing the IoT’s connectivity and software components.

Atmel mbed Xpro board

ARM is the lead maintainer for the mbed OS modules while it adds silicon partners, like Atmel, as platform-specific dependencies for the relevant mbed OS modules. Silicon partners are responsible for their platform-specific drivers.

Atmel’s mbed-enabled evaluation board is based on the low-power 2.4GHz wireless Cortex-M0+ SAM R21 MCU. Moreover, Atmel is expanding mbed OS support for its Wi-Fi modules and Bluetooth Low Energy products.

The fact that Atmel is adding mbed OS to its IoT ecosystem is an important nod for ARM’s mbed technology in its journey from merely a hardware abstraction layer to a full-fledged IoT platform. Atmel managers acknowledge that mbed technology adds diversity to embedded hardware devices and makes MCUs more capable.

Solid Software Foundation

There is a lot of code involved in the IoT applications and software is getting more complex. It encompasses, for instance, sensor library to acquire data, authentication at IoT gateways and SSL security. Here, the automatic software integration engine like mbed lets developers focus on their applications instead of worrying about integrating off-the-shelf software.

The mbed reference designs like the one showcased by Atmel during ARM TechCon are aimed at narrowing the development time with the availability of building blocks and design resources—components, code and infrastructure—needed to bootstrap a working IoT system. Atmel managers are confident that a quality software foundation like mbed could help bring IoT products to market faster.

Atmel’s mbed-enabled IoT evaluation board promises harmony between hardware and software. Apparently, chipmakers like Atmel are joining hands with ARM to bring the entire ecosystem — OS software, cloud services and developer tools — under one roof, and thus facilitate the creation of standards-based IoT products. Atmel’s mbed evaluation board clearly mirrors that effort to deliver a complete hardware, software and developer tools ecosystem in order to bring IoT designs quicker to market.

The platform comprises of mbed OS software for IoT client devices like gateways and mbed Device Server for the cloud services. ARM launched the mbed software platform in 2014 and Atmel has been part of this initiative since then.

mbed in Communications Stack

Additionally, Atmel has tied the mbed association to its SmartConnect wireless solutions to make the best of mbed’s networking stack in the Internet of connected things. The IoT technology is built on layers, and here, interoperability of communications protocols is a key challenge.

For a start, Atmel’s SAM R21-Xpro evaluation board is embed-enabled and is built around the R21 microcontroller, which has been designed for industrial and consumer wireless applications running proprietary communication stacks or IEEE 802.15.4-compliant solutions.

Next up, the evaluation board includes SAM W25 Wi-Fi module that integrates IEEE 802.11 b/g/n IoT network controller with the existing MCU solution, SAM D21, which is also based on the Cortex-M0+ processor core.

XPLAIN
Furthermore, Atmel is offering an mbed-enabled Bluetooth starter kit that includes SAM L21 microcontroller-based evaluation board and ultra-low-power Bluetooth chip BTLC1000, which is compliant with Bluetooth Low Energy 4.1. Atmel demonstrated a home lighting system at the ARM TechCon show floor, which employed SAM R21-based Thread routers that passed light sensor information to an mbed-enabled home gateway. Subsequently, this information was processed and sent to the mbed Device Server using a web interface.

Gemio is giving friendship bracelets an IoT makeover


This piece of smart jewelry combines self-expression with the ability to connect with friends in-person.


Friendship bracelets first emerged on the wearable scene in the 1970s, and have remained pretty much the same ever since. In order to evolve with the times, one Seattle startup has unveiled more intelligent and interchangeable jewelry for today’s tech-hungry and fashion-savvy world.

Gemio3

Whereas most wearable devices have a uniform appearance, Gemio boasts modular Gemsets that can be snapped on and off with ease. These Gemsets can be programmed with various light and special effects from a palette of colors, so you can create an entirely new look each and every day. You can even swap out designs in a matter of seconds via its accompanying mobile app.

Crafted with a social component in mind, Gemio is the first wearable to focus on connecting people rather than the gadgets themselves. The bracelet employs much of the technology commonly found in existing trackers and smartwatches, such as Bluetooth, an accelerometer, a gyroscope and 20 LEDs, but applies them in a different manner.

Gemio2

Using BLE connectivity and a mesh network, wearers are able to sync their Gemios through gestures like high-fives and handshakes. Once paired, the bands alert its user to their friends’ proximity through the detachable Gemsets. The unit not only recognizes who you’re with and responds to what you are doing, it also illuminates when your friends are nearby, playing a signature “light tone.” (Think of it as a personalized ringtone, but in lights.)

What’s more, the responsive bracelet can detect various gestures and allows users to assign light effects to them. For example, wave hello and Gemio plays a light show, or twist your wrist to make it sparkle.

Gemio1

The startup was founded in 2014, with some of its earliest backers including Tricia Black, the first vice president of sales at Facebook. Gemio joins the likes of JewelBots and several others in developing wearable products that appeal to girls with hopes of enticing more to pursue STEM-related disciplines.

TrackR atlas locates your lost items


You’ll never misplace things (or pets) again!


Whether you’re an organized or messy person, you inevitably lose things or forget the last spot you saw it. What is more frustrating is that you make a bigger mess just trying to find it. You can keep a mental map of where you put things in your home, but wouldn’t it be much easier if your phone did that for you? Now with TrackR atlas, you can.

CUIVYFVUkAASqHP

Fittingly named, TrackR atlas maps out your home and enables room-based item monitoring of your BLE-based items. This is the second project to come from the team that created the successful TrackR bravo, a small Bluetooth tracking device that attaches to your valuable items. Atlas works with bravo and other wireless trackers to better organize your home.

The TrackR atlas plugs into a wall socket in each room of your home, and utilizes both Wi-Fi and Bluetooth Low Energy radios to detect the presence of items that have TrackR devices or third-party Bluetooth-based trackers attached to them. From the Android and iOS app, you can locate which room all of your items are in your home.

Atlas can also notify you when things move around or leave the house. This is perfect if you have pets that tend to wander off. Among its other features, atlas has remote ringing, Amazon Alexa voice-activation, and is backed by the Crowd GPS network so you can track your items when they are missing outside of your home. You never have to aimlessly search for things again!

The tiny unit has an 802.11 b/g/n Wi-Fi radio with a range of 230 feet (70 meters), and Bluetooth 4.0 with a range up to 98 feet (30 meters). It supports wall sockets for the U.S., UK, Australia and most of Europe.

Tired of misplacing things? Head over to TrackR’s Indiegogo campaign, where they have already more than tripled their $50,000 goal. You’ll be able to pinpoint the location of your valuables starting June 2016.

Introducing a personal assistant to help you remember your things


THE O will make sure you never leave your valuables behind again.


With people always on the go and in a rush these days, it’s easy to leave important things behind by accident. Even if you’re on alert, an item can slip out of your pocket or purse without your knowledge. But thanks to THE O, not anymore.

Billed as “a comprehensive virtual personal assistant,” the smart accessory will notify you as soon as you forget or misplace one of your belongings. THE O can easily attach to just about anything, from your keys and wallet to your jacket and briefcase. The wearable unit comes in three different models: original and octopus (gunmetal rhodium), luxury (gold plated), and light (rubber).

The accessory works by connecting to an accompanying mobile app via Bluetooth and alerting you only when it needs to, acting as a virtual leash when you’ve moved too far away from your item. THE O can also check your essentials for you before leaving the house in the morning or after getting up from lunch, storing GPS location and time then marking needed items on appropriate days.

Focusing on a minimized size and a waterproof feature, its creators have designed a custom PCB to fit into its special ABS shell. The devices are assembled through ultrasonic welding, and a small PET slip is used to connect to the circuit. THE O itself measures only 4mm x 39mm x 29mm in size, so it’s certainly mall enough to be slipped into a pocket, sewn onto an umbrella or clipped onto a bag. Aside from that, the device’s coin-cell battery boasts a life of around 18 months.

Currently live on Kickstarter, THE O team is seeking $48,606. Pending all goes to plan, the first batch of units will ship in February 2016.
