MIT is developing shape-shifting interfaces


Thanks to MIT’s Tangible Media Group, interfaces that bend, hinge and curl will soon be a reality. 


Imagine if your iPad case automatically lifted up each time you received a message, or your Post-It notes folded down as you checked an item off your to-do list. Well, that may soon be a reality thanks to a team from MIT’s Tangible Media Group who has unveiled a technology for the rapid digital fabrication of customized thin-film shape-changing interfaces.

By combining the thermoelectric characteristics of copper with thermally sensitive polyethylene, the researchers were able to actuate the shape of the flexible circuit composites directly. The development of UniMorph can be broken down into a few steps, which begins with designing a digital model of the pattern in CadSoft EAGLE or Adobe Illustrator and then fabricating the structure using a standard printer, copper etching, hydrogen peroxide and hyrdochloric acid — the entire process is explained in great detail here.

The base of the interface is made up of two thin layers of material: Kapton on top, plastic polyethylene on the bottom. When these are heated up either using a third layer of copper conduits or exposure to light, they expand at different rates. This will cause the bottom layer to pull up the edges of the top, thereby creating a curling effect.

Layer Composition

Passive actuation can leverage access heat, like that given off from a lightbulb or the sun, to create simple shape transformations. Meanwhile, more complex and active shape-actuation can be achieved by designing resistive heating patterns into a flexible circuit. The uniMorph composite also allows for the embedding of additional electronics such as sensors, LEDs and MCUs.

Not only can the film bend, curl, twist and open like a flower, but uniMorph’s unique capabilities unlock the potential for things like the aforementioned smart Post-It notes and iPad covers, as well as responsive bookmark/reading lights that bend into place as you navigate the page.

According to Creative Applications, the listed examples each run on custom Arduino-compatible boards, and in some cases, the flexible circuits are produced in such a way that the ATmega328P can be soldered right on top. Intrigued? You can read all about the project in its paper here, or simply check out its video below.

Secured SAMA5D4 for industrial, fitness or IoT display


To target applications like home automation, surveillance camera, control panels for security, or industrial and residential gateways, high DMIPS computing is not enough.


The new SAMA5D4 expands the Atmel | SMART Cortex-A5-based family, adding a 720p resolution hardware video decoder to target Human Machine Interface (HMI), control panel and IoT applications when high performance display capability is required. Cortex-A5 offers raw performance of 945 DMIPS (@ 600 MHz) completed by ARM NEON 128-bit SIMD (single instruction, multiple data) DSP architecture extension. To target applications like home automation, surveillance camera, control panels for security, or industrial and residential gateways, high DMIPS computing is not enough. In order to really make a difference, on top of the hardware’s dedicated video decoder (H264, VP8, MPEG4), you need the most complete set of security features.

Life-Fitness-F3-Folding-Treadmill-with-GO-Console-2_681x800

Whether for home automation purpose or industrial HMI, you want your system to be safeguarded from hackers, and protect your investment against counterfeiting. You have the option to select 16-b DDR2 interface, or 32-b if you need better performance, but security is no longer just an option. Designing with Atmel | SMART SAMA5D4 will guarantee secure boot, including ARM Trust Zone, encrypted DDR bus, tamper detection pins and secure data storage. This MPU also integrates hardware encryption engines supporting AES (Advanced Encryption Standard)/3DES (Triple Data Encryption Standard), RSA (Rivest-Shamir-Adleman), ECC (Elliptic Curves Cryptography), as well as SHA (Secure Hash Algorithm) and TRNG (True Random Number Generator).

If you design fitness equipment, such as treadmills and exercise machines, you may be more sensitive to connectivity and user interface functions than to security elements — even if it’s important to feel safe in respect with counterfeiting. Connectivity includes gigabit and 10/100 Ethernet and up to two High-Speed USB ports (configurable as two hosts or one host and one device port) and one High Speed Inter-Chip Interface (HSIC) port, several SDIO/SD/MMC, dual CAN, etc. Because the SAMA5D4 is intended to support industrial, consumer or IoT applications requiring efficient display capabilities, it integrates LCD controllers with a graphics accelerator, resistive touchscreen controller, camera interface and the aforementioned 720p 30fps video decoder.

hmi-panels-sama5d4-atmel-processor

The MCU market is highly competitive, especially when you consider that most of the products are developed around the same ARM-based family of cores (from the Cortex-M to Cortex-A5 series). Performance is an important differentiation factor, and the SAMA5D4 is the highest performing MPUs in the Atmel ARM Cortex-A5 based MPU family, offering up to 945 DMIPS (@ 600 MHz) completed by DSP extension ARM NEON 128-bit SIMD (single instruction, multiple data). Using safety and security on top of performance to augment differentiation is certainly an efficient architecture choice. As you can see in the block diagram below, the part features the ARM TrustZone system-wide approach to security, completed by advanced security features to protect the application software from counterfeiting, like encrypted DDR bus, tamper detection pins and secure data storage. But that’s not enough. Fortunately, this microprocessor integrates hardware encryption engines supporting AES/3DES, RSA, ECC, as well as SHA and TRNG.

The SAMA5 series targets industrial or fitness applications where safety is a key differentiating factor. If security helps protecting the software asset and makes the system robust against hacking, safety directly protects the user. The user can be the woman on the treadmill, or the various machines connected to the display that SAMA5 MCU pilots. This series is equipped with functions that ease the implementation of safety standards like IEC61508, including a main crystal oscillator clock with failure detector, POR (power-on reset), independent watchdog timers, write protection register, etc.

Atmel-SMART-SAMA5D4-ARM-Cortex-MPU-AtmelThe SAMA5D4 is a medium-heavier processor and well suited for IoT, control panels, HMI, and the like, differentiating from other Atmel MCUs by the means of performance and security (not to mention, safety). The ARM Cortex-A5 based device delivers up to 945 DMIPS when running at 600 MHz, completed by DSP architecture extension ARM NEON 128-bit SIMD. The most important factor that sets the SAMA5D4 apart from the rest is probably its implemented security capabilities. These will protect OEM software investments from counterfeiting, user privacy against hacking, and its safety features make the SAMA5D4 ideal for industrial, fitness or IoT applications.

IoT, digital mesh and smart machines among Gartner’s top tech trends


A look at the 10 technology trends that Gartner believes will be strategic for organizations in 2016.


During its annual Symposium/ITxpo, Gartner reveals the top 10 technology trends that will be strategic for organizations to implement in the coming months. This year, you’ll once again notice some rather familiar names on the recently-revealed list, along with a few newcomers that are expected to have an impact on the enterprise in 2016. According to the research firm, these notable trends include the Internet of Things (of course!), the Information of Everything, 3D printing and digital mesh.

Social_SS_137156231-2

Let’s take a closer look…

The Device Mesh

The device mesh refers to an expanding set of endpoints people use to access applications and information or interact with people, social communities, governments and businesses. Think of it as the glue between the countless mobile, wearable, consumer, home, automotive and environmental devices that make up the IoT.

Ambient User Experience

The device mesh creates the foundation for a new continuous and ambient user experience. Immersive environments delivering augmented and virtual reality hold significant potential but are only one aspect of this experience, which seamlessly flows across a shifting set of devices and interaction channels blending physical, virtual and electronic environment as the user moves from one place to another.

3D Printing Materials

Advances in the next-gen technology have already paved the way for 3D printers to spit out a range of materials, including everything from carbon fiber and glass to conductive ink and electronics. These innovations are driving user demand, as the practical applications for such equipment begins to expand into more sectors. According to Gartner, the extensive lineup of 3D-printable materials will drive a CAGR of 64.1% for enterprise 3D printer shipments through 2019.

Information of Everything

More devices, more information. Everything in the digital mesh produces, uses and transmits information. And this goes well beyond just textual, audio and video, but encompasses sensory and contextual as well. The so-called “Information of Everything” will address this influx with strategies and technologies that link data from all these different sources. As the research firm puts it, information has always existed everywhere but has often been isolated, incomplete, unavailable or unintelligible; now, the advent of semantic tools and other emerging techniques will finally give proper meaning to it all.

Advanced Machine Learning

In advanced machine learning, deep neural nets (DNNs) move beyond classic computing and information management to create systems that can autonomously learn to perceive the world — all on their own. The explosion of data sources and complexity of information makes manual classification and analysis infeasible and uneconomic. DNNs automate these tasks and make it possible to address key challenges related to the information of everything trend. This area is rapidly evolving, and organizations must assess how they can apply these technologies to gain the competitive edge.

Autonomous Agents and Things

Machine learning gives rise to a spectrum of smart machine implementations, which includes robots, autonomous vehicles and virtual personal assistants, that act in an autonomous (or at least semi-autonomous) manner. While advances in physical smart machines such as robots receive some mainstream attention, the software-based smart machines have a more near-term and broader impact. In fact, VPAs like Google Now, Microsoft’s Cortana and Apple’s Siri are becoming smarter and are precursors to autonomous agents. The emerging notion of assistance feeds into the ambient user experience in which an autonomous agent becomes the main user interface. Instead of interacting with menus, forms and buttons on a smartphone, the user speaks to an app, which is really an intelligent agent.

Adaptive Security Architecture

The complexities of digital business and the algorithmic economy combined with an emerging “hacker industry” significantly increase the threat surface for an organization. Relying on perimeter defense and rule-based security is inadequate, especially as organizations exploit more cloud-based services and open APIs for customers and partners to integrate with their systems. Gartner points out that IT leaders must focus on detecting and responding to threats, along with more traditional blocking and other measures to prevent attacks. Application self-protection, as well as user and entity behavior analytics, will help fulfill the adaptive security architecture.

Advanced System Architecture

The digital mesh and smart machines require intense computing architecture demands to make them viable for organizations. Providing this required boost are high-powered and ultraefficient neuromorphic architectures. Fueled by field-programmable gate arrays (FPGAs) as an underlining technology for neuromorphic architectures, there are significant gains to this architecture, such as being able to run at speeds of greater than a teraflop with high-energy efficiency.

Mesh App and Service Architecture

Monolithic, linear application designs are giving way to a more loosely coupled integrative approach: the apps and services architecture. Bringing mobile and IoT elements into the app and service architecture creates a comprehensive model to address back-end cloud scalability and front-end device mesh experiences. Looking ahead, application teams must devise new modern architectures to deliver agile and flexible cloud-based applications with dynamic user experiences that span the digital mesh.

IoT Platforms

The Internet of Things will play an integral role in the digital mesh and ambient user experience, and the emerging and dynamic world of  IoT platforms is what makes them possible.

Atmel Studio 7 is now live!


Atmel Studio 7 accelerates MCU designs for both developers and Makers alike, bridging the gap between the MakerSpace and MarketPlace.


For those who may have attended the recent World Maker Faire in New York, this announcement should come as no surprise. However, if you were unable to get to the New York Hall of Science to swing by the Atmel booth or sit in on one of our panel discussions over the weekend, we’ve got some great news. The highly anticipated Atmel Studio 7 is now live!

Studio7__Google+_1160x805

Atmel Studio is a comprehensive, free integrated development environment (IDE) for microcontroller design using both Atmel | SMART ARM-based and AVR MCUs. What’s more, we are also excited to be launching Atmel START — a new, extremely intuitive graphical platform for creating and configuring embedded applications that allow developers to build custom software platforms.

Due to increased complexity and more demanding requirements, embedded developers are turning to IDEs to deliver more intelligence, performance and ease-of-use. Based on the latest Microsoft Visual Studio Shell, Atmel Studio 7 dramatically reduces overall design time by delivering significant performance enhancements for developing and debugging with a simple user interface, improved responsiveness for consumer, industrial and Maker markets, and much more. Plus, the brand-spankin’ new IDE provides real-time application data and power visualization to better optimize application performance and power utilization.

Ideal for the Maker community, the IDE lets Arduino developers quickly port their sketches created in the Arduino environment as C++ projects, and seamlessly migrate their prototypes into the professional Studio 7 environment. This will further streamline a Maker’s ability to help migrate their projects from ‘the MakerSpace to MarketPlace.’

Given the rise of the Internet of Things market and the projected billions of devices to follow, high quality, well integrated embedded software is key to enable designers to devise robust, smart solutions based on today’s connectivity and security standards. Cognizant of this, we are pleased to launch Atmel START which is a web-based tool that helps developers easily integrate basic software building blocks and focus on their own applications rather than having to deal with the headache of configuration and integration.

“Atmel Studio 7 IDE and Atmel START extend our commitment to bridge the gap between the Maker and professional environments, accelerating time-to-market for developers of all levels,” says Steve Pancoast, Atmel Vice President of Applications, Software and Tools. “Our new, innovative development tools and software provide Atmel’s customers with solutions for embedded system designs in low power and wireless communications such as our power visualizer and Atmel START. We are committed to bringing the best tools to market, enabling developers of all levels — from professionals to students, hobbyists and Makers — to get their projects quickly to market.”

Atmel START gives software developers the ability to graphically select software components and configure them for Atmel’s large family of evaluation boards or for their own custom hardware. Developers can build software platforms consisting of low-level drivers, advanced middleware, Real Time Operating Systems (RTOS), high-level communication stacks and more, as well as download the configured software package into their own IDE and make their application.

Atmel START supports graphical configuring of pin-muxes, along with clock trees, and the configured software package can be downloaded for a variety of supported development environments, such as Atmel Studio 7, IAR Embedded Workbench and Keil µVision. In addition to all that, the tool is entirely web-based so no installation is required before you get started — and the downloaded code will always be up-to-date.

“The Atmel START platform makes it easy for developers to get projects off the ground quickly and obtain the most benefit from working with ARM Keil MDK tools,” adds Reinhard Keil, ARM Director of Microcontroller Tools. “By using CMSIS, Atmel has once again proven the value of creating a platform built on a standards-based approach. Atmel START creates a robust and portable software management system that makes it easy for developers to deploy applications in any environment.”

Interested? Atmel Studio 7 is free of charge and is integrated with the Atmel Software Framework (ASF) — a large library of free source code with 1,600 project examples. Those wishing to get started with the IDE can head over to its official page here, as well as explore Atmel START in more depth by downloading the latest white paper on the platform.

Angee is an autonomous home security system


This smart system doubles as both your security guard and personal assistant.


Did you know that every 13 seconds, a home is broken into in the United States? In fact, 41% of burglaries happen when a system isn’t armed. Although it’d be nice to have guards protecting our homes, not all of us have that luxury or the convenience.

972a0c953870584c65e8dc47a83c622b_original

Angee is an advanced security and communication system that changes how you protect and connect to your humble abode. The device provides a 360-degree view of your household and is loaded with several valuable features, including voice recognition, at-the-door identification, motion-detecting rotation, advanced learning and cordless portability. By learning the daily habits of your family members, Angee can autonomously arm and disarm herself.

Setting up Angee is easy — you simply connect the device with your smartphone and add security points around throughout your rooms to secure your home. The unit provides full perimeter protection by using security tags on your doors and windows so the system knows exactly who comes and goes. In fact, it can determine suspicious activity such as movement by someone it doesn’t recognize through detecting entry and exit patterns, changes in background noise, Bluetooth signal in phones and voice differentiation. If Angee happens to sense suspicious activity, a notification is sent to your smartphone (or smartwatch) via its accompanying app so you can stream video in real-time. Plus, you can receive updates on temperature, humidity or just take a look around, if you so choose.

81581e38ccaeb35b5c91e1a36f96d899_original

At roughly five by three inches, Angee boasts an ARM processor at its core and weighs about 1.3 pounds. Angee’s camera rotates to provide full coverage of a room and employs an array of six passive infrared sensors for 360-degree motion detection. The security tags are powered by two AAA-batteries and feature Bluetooth connectivity, which is not only used to wirelessly communicate with Angee, but also sense nearby phones to identify who is home. And should the power go out, not to worry. The gadget’s built-in battery enables it to sustain energy, and more importantly, continue monitoring. Similarly, if your Wi-Fi goes offline, Angee will alert you while still recording any activity and saving the footage to its local storage.

The makers of Angee built the system by learning from people’s experience with early versions of smart security systems. The team has focused on creating the smartest home security system ever — one that is useful, convenient, and tailored to each individual’s needs. And that’s not all. It can double as a personal assistant by recording all-too-often missed moments for a family member who is away, answering calls, checking the calendar and even reminding you to close the windows if rain is in the forecast.

2743b5d54eb560c36a6750ed1cf0785a_original

“In the future, smart hardware and technologies will be omnipresent. They will be easy to use and perfectly integrated into our environment.

CUJO guards all connected home devices from hackers


CUJO protects your home networks against hacks, viruses, malware and other virtual intrusions.


From Ashley Madison to Sony, the latest string of data breaches have demonstrated the significance of security in our increasingly electronic world. The days of protecting your home with just an alarm system or some anti-virus softwre are over; in fact, anything that is connected to the Internet has become a fairly easy target for malicious hackers. With this in mind, a California-based startup has introduced a gadget, called CUJO, that will guard all smart home devices against the most sophisticated virtual intrusions, from malware to phishing attempts.

CUJO-DEVICE

One of, if not, the most intriguing attributes would have to be its simplicity. CUJO acts as a plug-and-play gatekeeper on the front end of your router with an Ethernet cable, blocking hackers and other threats before they can reach a home network and everything connected to it. The elegantly-designed unit will inspect all of the packets of data leaving and entering your home, and even analyze your device behavior so that it can detect anomalies as soon as they occur.

“CUJO goes beyond traditional security by using a multilayer approach that combines firewall, antivirus, and malware typically found in separate devices,” the startup writes. “Unlike traditional solutions, CUJO adapts and reacts when your home is attacked and does not rely just on libraries of known malware issues. We analyze a humongous amount of behavioral data in our cloud and push learnings from one home to all CUJO protected homes.”

3051124-slide-s-2-cujo-is-more-than-a-web-security-avatar

Another thing you will notice about CUJO is that it decided to forgo a display and replaced it with an ambient interface. Instead, you can easily monitor activity from afar using its accompanying mobile app. And should your network ever be attacked, a notification will be immediately sent to your smartphone with more details.

In terms of hardware, CUJO boasts 4GB of Flash memory, two 1GB Ethernet ports, 256-bit AES encryption and cryptographic hardware acceleration.

“We use bank-level security to protect the communication between your CUJO and the CUJO cloud,” its creators add. “Our device will contain several layers of hardware security, making it difficult to break into it even with direct physical access to it.”

Ready to safeguard your home devices from hackers? Head over to CUJO’s Indiegogo campaign, where the team is seeking $30,000. Delivery is expected to begin in March 2016.

Secure your Raspberry Pi and Linux applications with ZymKey


ZymKey makes it easy to secure your IoT applications and manage them in the real world.


More times than not, developers are faced with two bad options: either deliver a substandard product quickly, or reinvent the wheel and miss the market altogether. Luckily, one Santa Barbara-based startup has come up with a solution, not just a band-aid but a true fix to the all too common conundrum. Introducing ZymKey, a tiny, low-cost piece of hardware for authenticating and encrypting data between Internet of Things devices.

68c7c9312f7e58953657dbc953040581_original-1

The key integrates silicon and software into a simple, ready-to-go package that will automatically work with Raspberry Pi and other Linux gadgets. What’s nice is that the ZymKey integrates seamlessly with Zymbit’s existing IoT platform, which includes Zymbit.Connect software, the Zymbit.City community and the Zymbit.Orange secure IoT motherboard that was on display back at Maker Faire Bay Area.

Your touchscreen can now seamlessly transition between hover, finger and glove touch


The new maXTouch mXT641T family is the industry’s first auto-qualified self- and mutual-capacitance controller meeting the AEC-Q100 standards for high reliability in harsh environments.


Optimized for capacitive touchpads and touchscreens from five to 10 inches, Atmel has expanded its robust portfolio of automotive-qualified maXTouch controllers with the all-new mXT641T family. These devices are the industry’s first auto-qualified self- and mutual-capacitance controllers meeting the AEC-Q100 standards for high reliability in harsh environments.

Glo1

The maXTouch mXT641T family incorporates Atmel’s Adaptive Sensing technology to enable dynamic touch classification, a feature that automatically and intelligently switches between self- and mutual-capacitance sensing to provide users a seamless transition between a finger touch, hover or glove touch. As a result, this eliminates the need for users to manually enable ‘glove mode’ in the operating system to differentiate between hover and glove modes. Adaptive Sensing is also resistant to water and moisture and ensures superior touch performance even in these harsh conditions.

The latest family of devices support stringent automotive requirements including hover and glove support in moist and cold environments, thick lens for better impact resistance, and single-layer shieldless sensor designs in automotive center consoles, navigation systems, radio interfaces and rear-seat entertainment systems. The single-layer shieldless sensor design eliminates additional screen layers, delivering better light transparency resulting in lower power consumption along with an overall lower system cost for the manufacturer.

Glove

“More consumers are demanding high-performance touchscreens in their vehicles with capacitive touch technology,” said Rob Valiton, Senior Vice President and General Manager, Automotive, Memory and Secure Products Business Units. “Atmel is continuing to drive more innovative, next-generation touch technologies to the automotive market and our new family of automotive-qualified maXTouch T controllers is further testament to our leadership in this space. Atmel is the only automotive-qualified touch supplier with over two decades of experience in designing, developing, and manufacturing semiconductor solutions that meet the stringent quality and reliability standards for our automotive customers.”

Disney researchers found a way for devices to communicate using LEDs


Visible Light Communication enables the interaction between objects using only LEDs.


If devices are going to communicate with one other, more times than not it’s going to be done through Bluetooth or Wi-Fi. However, wireless networks aren’t always available and Bluetooth can drain battery life. Knowing this, a Disney Research team has come up with an alternative way for Internet of Things objects to ‘talk.’ How, you ask? Through LED lights.

1423280201312294436

Unlike incandescent or fluorescent bulbs, the brightness of LEDs can be controlled with extreme precision. Meaning, they can be turned on and off at very high frequencies that are faster than the human eye can detect. Aside from that, LEDs can even be used as receivers just like photodiodes.

Similar to how two ships passing in the night can communicate via Morse code, a couple of IoT gadgets can now secretly converse through the visible light generated by an LED — a method that the team calls Visible Light Communication, or VLC. Not only can it illuminate a room, but the MCU inside each bulb is capable of transmitting and receiving data.

“VLC creates opportunities for low-cost, safe, and environmentally friendly wireless communication solutions. We focus on connected toys and light bulb networks,” the team writes. “Our work targets a full system design that spans from hardware prototypes to communication protocols, and applications.”

Though the concept of “Li-Fi” has been around for a while, as expected, it would appear that many of VLC’s initial examples are focused primarily on toys. (It is Disney, after all!) Among them included a toy car that can turn on its own lights and come to life when placed near a lamp, as well as a princess dress whose embedded LEDs are activated whenever a wand with its own light comes near.

“LED-to-LED Visible Light Communication allows interaction between toys by only using LEDs. No dedicated hardware is required. When multiple devices are networked with each other, we organize the communication with our software protocols,” the researchers add.

However, the technology has other potential applications as well, with an adapter connected to the headphone jack of a smartphone or tablet to receive signals from overhead lights operating at wavelengths unnoticeable by the human eye. This, for instance, opens the door for LED emitters to be placed around a store to beam notifications to the smartphones of shoppers.

Using a simple mobile app on the device, the lightbulb data can be used to tell a story and visualize both pictures and text. When off, no data is transmitted. When switched back on, the storytelling continues.

As you can see in the photo above, the researchers employed various Arduino Uno boards (ATmega328) as part of the study’s testbed. Read all about the project here.
