Poland-based supplier Modulowo has introduced an embedded development board for Intel’s small form factor IoT module, known as Edison.

Modulowo Explore E

It takes the form of a breakout board for Intel Edison Compute Module providing interfaces and connectors to additional modules, such as sensors, touch switches, motor controllers and LED drivers and GPS.

It is likely to be used for IoT design prototyping but can also be used as an educational aid.

Called Explore E the breakout board includes two proprietary duoNECT connectors for expansion modules – GPIO, SPI, UART and I2C interfaces connectors, two micro USB (USB OTG and USB/UART converter).

There is also a 12-bit analogue-to-digital converter for measuring analog signals, voltage logic level translators (tolerates +3,3V/+5V signals).

The IoT module also supports a GPS peripheral.

Edison is a built around a dual-core Intel Atom processor and will run various maker operating systems such as Arduino, Linux, and Python. It is also compatible with C, C ++ and JavaScript.

Cisco’s corporate venture capital arm is making an investment in Kii, the Japanese cloud services provider used by internet of things (IoT) device developers.

Cisco sees potential in Kii's cloud software approach to facilitating the development of both business/industrial and consumer-focused IoT applications.

A new Kii cloud software, dubbed the Thing Interaction Framework, focuses on common IoT use cases around sensor-cloud-app interactions (like sensor state registration/retrieval, trigger-driven command execution on devices).

Kii claims this results in a reduction in the amount of server code needed to implement them.

According to Kii, which has more than 140 million users and data centres in in Japan,US and China, IoT device manufacturers and mobile app developers can adapt and customise the framework through new and updated SDKs.

Masanari Arai, CEO of Kii, said: the investment will help the firm to introduce our platform and various IoE solutions throughout the world and help us execute on the larger IoE vision.”

Miyuki Suzuki, president and general manager, Cisco Systems G.K, believes the investment will "support the development of a platform that offers the ease of use, features and scalability needed to bring IoE solutions to market rapidly.”

Kii becomes the second company in Japan to receive a direct investment from Cisco Investments.

“Cisco Investments continues to capture innovation in Japan with our investment in Kii,” said Hideaki Yajima, Head of Corporate Development, Japan, Cisco Systems G.K. “Startups expanding into other markets are a key component of Cisco Investments’ strategy globally.”

Connected cars with wireless communications links, telematics and vehicle advanced driver assistance systems (ADAS) will require increasing levels of electronic test, write John Russell, Bill Mckinley and Matt Hodgetts

Figure 1 gives an idea of how the percentage that the electronics content contributes to the total cost of a car has been steadily rising, and is expected to keep rising.

The technological sophistication of modern automobiles means that they are very different from the models of the past.

In many areas conventional mechanical systems have been replaced by sophisticated electronics. This is allowing substantial improvements in their operational efficiency, as well as enabling a wider range of new features and functionality to be benefited from.

In many ways the cars that are being introduced onto the market today have much more in common with computing devices than they do with their predecessors. They will, in some cases, need to process in excess of 25Gbyte of data per hour in order to fulfil all their assigned tasks.

Until now the impetus for implementing digital technology into automotive designs has been mainly for the purpose of eliminating mechanical elements. Through this, marked reductions in vehicle weight are now happening, which in turn improves fuel economy figures.

This is just one aspect. Vehicle manufacturers are moving ever closer to their goal of the ‘connected car’. Such vehicles will integrate systems supporting a broad array of different communication technologies - and through these it will be possible to address issues relating to driver/passenger comfort and safety, as well as vehicle security.

It will also make it easier to ensure the vehicle is kept in good working order and that maintenance/repair requirements are identified in a timely manner.
Industry analysts firm Gartner has forecast that by 2020 there will be over 250 million connected cars on our roads. These vehicles will employ various different wireless protocols. These include Wi-Fi, LTE mobile, Bluetooth, NFC and ZigBee, to name just a few.

This presents vehicle manufacturers and their technology partners with a sizeable and multifaceted challenge. Not only do they need to derive an accurate benchmark of each of these protocols in isolation, on top of this they must gain a firm grasp of how the wireless signals will interact with one another and also what influence the extremely difficult automotive environment in which they are located is likely to have on performance.

There are several different parts of a vehicle’s operation where the heightened degree of connectivity now envisaged is destined to have real value. These include: infotainment and communications; telematics; and vehicle advanced driver assistance system (ADAS).

Car makers want to provide all these extra capabilities, but given the highly competitive market they need to be able to do this in a way that doesn’t bring excessive additional costs with it. It is crucial, therefore, that testing activities do not slow down the production process or require allocation of extra engineering resources.

Figure 2 gives further details about some of the different applications that are encompassed in each of these three areas

Main test requirements

Though in the telecoms sector, data rates are the overriding concern, for connected cars it will be low latency and elevated reliability that matter.

Through the test equipment they have sourced, engineers need to be able to not only verify performance of the automotive wireless technologies being utilised, but in addition carry out comprehensive interference and interoperability tests. So, in addition to rapid throughput, a breadth of test parameters is basically mandatory.

Scalability is also of great importance. Testing within a laboratory scenario is just the beginning. The product lifecycle as a whole has to be adequately attended to, not just isolated elements. Once the necessary tests have been accomplished during the development phases, these activities need to be ramped up to meet mass production demands. It is important that the specified equipment is able to deal with this migration.

The role of 802.11p in connected cars

802.11p is set to form the foundation on which much of the functionality in connected cars will be constructed. This is an approved amendment to the universally recognized 802.11 WLAN standard. It deals with wireless access inside an automotive setting and will support Intelligent Transportation System (ITS) applications as they start to emerge.

Occupying the 5.9GHz frequency band, 802.11p utilises a series of 10MHz wide channels (six service channels, plus an addition channel for control purposes). The priority with this protocol is not offering a high data capacity, it is about establishing a highly reliable, low latency wireless data link.

This more deterministic technology will make it possible for vehicle-to-vehicle or infrastructure (V2V/V2I) communication to be implemented. A vehicle will be able to broadcast data relating to its current position and the speed/direction in which it is travelling. This data may then be picked up and, if necessary, acted upon by other vehicles that are in the vicinity.

Qualcomm and Intel have announced interoperability between their WiGig products.

This will help pave the development of 802.11ad WiGig devices that connect at speeds of up to 4.6 Gbps.

Bringing spectrum in the 60 GHz band to Wi-Fi 802.11ad will address rising dimageata demand in homes, enterprises and carrier networks.

802.11ad enables 4K display connectivity to tri-band (2.4 GHz, 5 GHz and 60 GHz) Wi-Fi networking and high-speed cellular offload.

If you think CES is an obvious place to showcase Bluetooth innovation, the Bluetooth Special Interest Group agrees. The SIG has announced the winners for the 2016 Bluetooth Breakthrough Awards, which were held in Las Vegas, off the back of CES.

This one caught Gadget Master’s eye – or should I say, ear? – as I remember hearing about aptX for the first time at a CSR audio demo a couple of years ago. Anyway, Qualcomm has officially unveiled aptX HD, an enhanced version of the codec that offers 24-bit music data, over low-power wireless links, compared with the 16-bit (“CD-quality”) of the original aptX.

The original CSR VibeHub demo, back in 2014, was effectively a CES Preview, and the latest Qualcomm announcement was also timed with CES 2016 in mind.

"Today consumers enjoy the benefits and freedom of wireless audio on the wide variety of aptX enabled devices available but demand for higher resolution audio is growing to fulfil the desire for the most premium listening experience possible," said Anthony Murray, general manager, Qualcomm Technologies International. "With aptX HD, we are helping device manufacturers to reduce development time and quickly meet demand."

CSR8675

aptX HD is immediately available as part of the CSR8675 Bluetooth audio SoC, says Qualcomm (which bought CSR last October). The chip features:

• Integrated high performance stereo DAC & ADCs
• 24 bit digital audio support
• 2 x I2S interfaces
• 1 x SPDIF interface
• 2 x additional GPIOs (over CSR8670)
• Bluetooth v4.1 support
• 16Mb internal eflash and up to 64Mb external serial flash
• 6 x Capacitive touch sensor inputs
• Up to six digital microphone inputs
• Support for ANC feed-forward architecture

A diagram of the chip is pictured, above right.

The same challenge remains, of course: sending high quality audio wirelessly over Bluetooth by compressing the large audio files so that they can be transmitted through the wireless pipeline without affecting the listening experience quality. With low power usage.

Qualcomm says the new codec retains backward compatibility with all Bluetooth devices containing 'classic' aptX.

You can read more about aptX HD on the Qualcomm website - Introducing aptX HD: meeting the need for hi-resolution wireless audio.

As well as accepting a 24-bit audio input, 24-bit audio resolution is maintained by using an extra two bits in each of the four sub-bands of processing. This results in lower signal-to-noise ratio (the signal strength relative to background noise) through the encode/decode cycle and less distortion, making aptX HD ideal for use as part of a high-resolution audio solution.

SVS

Just to be precise, CSR itself acquired the technology, buying the Belfast-based audio codec firm APT Licensing back in 2010.

Interestingly, the audio coding algorithm originated from PHD research at Queens University Belfast by Dr. Stephen Smyth in the late 1980's and was adopted by Hollywood and the radio industry.

More recently, in 2004 he setup Smyth Research LLC to promote and market the SVS algorithm, his latest invention. This is described as "A revolutionary audio process that emulates, in headphones, the complete experience of listening to actual loudspeakers in an actual room, in up to eight-channel surround sound."

The emulation includes the precise localisation of all the speakers in the room, the room acoustics, and the response of the speakers and all electronics in the emulated system.

The emulation is essentially perfect, meaning that in immediate A/B comparison between the actual speakers and the headphones, listeners say the two are indistinguishable.

Products include the Smyth Realiser A8.

High Def Bluetooth audio

Getting back to High Def Bluetooth audio, a couple of interesting reads can be found here (Can aptX give you better sound over Bluetooth?) and here (Does Bluetooth Audio Still Suck?) for the interested.

What are your thoughts on Bluetooth and high-quality audio? A contradiction in terms? Or are you a convert, perhaps? Leave a comment below.

Check out this video, which Sony claims is the “world’s first 48K 360° video”. Its filmed with the Sony Xperia Z5 Compact, which supports 4K imaging. It’s 360° but is it 4K or 48K?

It was filmed at the Rise Ski & Snowboard Festival in Les Deux Alpes, France, with the 360 degree video shot on twelve Xperia Z5 Compact devices. Each device filming simultaneously in 4K. By Sony's count that makes it a 48K video!

In a post on the official Sony blog, Anthony Devenish writes:

 

The short film is the result of an ambitious, creative R&D experiment, where each Xperia Z5 Compact device was mounted on a custom 3D printed rig. We set about capturing scenes from the slopes, including freestylers performing jaw dropping tricks in the park, high-speed racers on a giant slalom course and the stunning panorama looking out across some of the Alp’s best known peaks. The footage from each phone was edited together to create our first 360 degree video, showcasing the unique capabilities of Xperia Z5’s camera technology.

You can interact with the video to pan around and explore the environment. That's a cue for yet another mention of Cardboard - you could watch the video with the Google Cardboard headset and the YouTube Android app, for the fuller immersive effect.
