This is the world’s first reference design for integrated solar and lithium-ion (Li-ion) battery power systems for small unmanned aerial vehicles (UAVs). By combining Alta Devices’ lightweight solar panel technology with PowerOasis’ expertise in hybrid power systems, small UAV developers can focus on leveraging their core expertise in aircraft design and performance.

“Up until now, it’s been nearly impossible to develop a hybrid solar/Li-ion UAV architecture for small aircraft because the solar technology compromised the design too severely. That is no longer true with Alta Devices’ solar technology,” said Pete Bishop, CTO of PowerOasis.

The reference architecture will target 2-4 meter (6.5-13 feet) span UAVs, using 5s-7s Li-ion batteries. Features include high efficiency, light weight, modular power systems, management of battery packs using a cell vendor agnostic, flexible battery management system (BMS), communication to ground control and on-board auto pilot with continuous real time power and energy data and conditioned power outputs for critical power and payload systems.

“In the past, a UAV manufacturer had to work with multiple companies to obtain the solar technology, downstream electronics, and power management software to create a solar/Li-ion hybrid powered system. Then, they had to design the system themselves,” said Alta Devices Chief Marketing Officer, Rich Kapusta. “By working together and providing a complete architecture for a well-crafted power system, PowerOasis and Alta Devices are streamlining the UAV development process. We are providing a complete system for electric aircraft and UAVs, eliminating the distraction and time required to focus on the intricacies of power design.”

Aircraft designers will be able to use the reference design to manage the complete energy generation, storage and power management system for a UAV. This is without having to bring this capability in-house, saving time and resources than can be better allocated to payload design and aircraft aerodynamics.

Many aircraft companies are turning to solar to provide added endurance to UAVs. A typical battery-powered UAV can normally stay aloft for only a few hours. With solar added to the wings, the same aircraft could fly all day.

The targeted release-date for the design is late 2017 and it will be available initially through Alta Devices and PowerOasis.

PowerOasis is the industry leader in 50W to 20kW hybrid power systems & energy efficiency solutions for a wide range of applications, from telecoms to transport and military deployments, combining in-house power electronics and software expertise enabling bespoke or high volume, high quality, leading edge power solutions.

XMOS in Bristol has launched a family of voice processors to provide far-field voice capture using arrays of MEMS microphones. The move marks a shift away from general purpose microcontrollers and AVB Ethernet controllers and into the market for voice controlled equipment such as Amazon’s Echo and Apple’s home speaker.

The XVF3000 has optional support for Sensory’s TrulyHandsfree technology, the industry’s leading voice-trigger solution and the Xcore architecture provides a flexible and cost effective always-on voice interface in a single device.

XMOS also announces the availability of a development kit (the XK VF3100 C43), which includes an XVF3000 processor card and a 4-mic circular microphone array. This kit provides a quick way to start developing far-field voice capture applications.

“Today is a very significant day for XMOS. We’re introducing XVF3000 and VocalFusion Speaker [development kit] as the first in a range of voice capture products. Based on our powerful and flexible xCORE microcontroller architecture, XVF voice processors open up new possibilities for designers looking to deliver high performance voice capture in a very cost-effective form factor,” said Mark Lippett, CEO at XMOS. “We’re excited to be at the forefront of the revolution driven by products like Amazon Echo and Google Home, which have shown the possibilities for voice interfaces. We are working worldwide with customers and partners to accelerate the adoption of voice as the interface of choice for the Internet of Things.”

The XVF3000 devices include speech enhancement algorithms that include an adaptive beamformer, which uses signals from four microphones to track a talker as they move, coupled with high performance full-duplex, acoustic echo cancellation. The controllers can be easily integrated with an applications processor or host PC via either USB for data and control or a combination of I2S and I2C. Developers can quickly add custom voice and audio processing using the XMOS free development tools.

XVF3000 devices are available immediately from XMOS, and the VocalFusion Speaker Development Kit will be available in July. Developers can register for early access to the Beta program and download further information at: www.xmos.com/xcorevocalfusion.

FreeRTOS moves to 64bit

June 27, 2017 by · Leave a Comment
Filed under: News 

The world’s most popular real time operating system, FreeRTOS, has updated to version 9, supporting 64bit microcontrollers for the first time

FreeRTOS V9.x.x, deveoped and maintained in Bristol, is a drop-in compatible replacement for FreeRTOS V8.x.x that still supports 32bit operation and adds new features, enhancements and ports.

Two new configuration constants that allow FreeRTOS to be used without the need for any dynamic memory allocation have been introduced. through the configSUPPORT_STATIC_ALLOCATION and configSUPPORT_DYNAMIC_ALLOCATION constants.

The Win32 demo located in the /FreeRTOS/demo/WIN32-MSVC-Static-Allocation-Only directory is provided as a reference of how to create a project that does not include a FreeRTOS heap at all, and therefore guarantee no dynamic memory allocation is being performed.

Other additions include:

  • Creating Tasks and Other RTOS Objects Using Statically Allocated RAM
  • Forcing an RTOS Task To Leave the Blocked State
  • Deleting Tasks
  • Obtaining a Task Handle from the Task Name
  • Enhancements to the GCC ARM Cortex-A port layer relating to how the port uses the floating point unit.
  • Update the ARM Cortex-M RTOS ports that use the memory protection using (MPU).
  • Added vApplicationDaemonTaskStartupHook() which executes when the RTOS daemon task (which used to be called the timer service task) starts running. This is useful if the application includes initialisation code that would benefit from executing after the scheduler has been started.

Bristol shows plans for major new university campus

June 26, 2017 by · Leave a Comment
Filed under: News 

The University of Bristol has revealed its plans for the new £300 million campus next to Bristol Temple Meads and is urging local businesses and industry to feed into a large-scale consultation.

The Temple Quarter Enterprise Campus development will be one of the city’s most significant regeneration projects in recent history, with 35,000 sq m of flexible space for teaching and innovation, including EngineShed 3.

One of its key goals is to work with industrial partners to develop a talent pipeline of graduates who will support the city’s successful digital cluster.

The University is encouraging businesses to share their views and help shape the new campus by taking part in a public consultation, which will run online from 19 June to 21 July.

There will also be exhibitions of the plans at Engine Shed by Bristol Temple Meads and Beacon House on the Triangle from 20 June to 7 July, plus special consultation events at Engine Shed and Paintworks.

The seven-acre site, which spans the derelict former Royal Mail sorting office and part of Arena Island, will be close to business incubation centre Engine Shed, home to the University’s award-winning Bristol SETsquared Centre, which will also be expanding into new premises within the Temple Quarter Enterprise Zone.

A range of new degree programmes will be designed and developed in collaboration with industry and other partner organisations, to ensure students educated on the Temple Quarter Enterprise Campus are equipped with the knowledge, skills, values and resilience to thrive and lead in a rapidly changing world.

“The new campus will focus on the digital technologies of the future and the skills, ethics, business models and infrastructure that turn digital opportunities into jobs, wealth and wellbeing that benefits the whole of society,” said Prof Dave Cliff, who is leading the academic side of the project. “We are working with partners, large and small, to put innovation at the heart of our campus and to build a talent pipeline of creative graduates who embrace social responsibility as well as opportunity. These graduates will be prepared to tackle global challenges that we can’t yet imagine.

“Our plan is for University staff and students to be co-located with partners from industry and commerce in the new buildings. We intend to work with our partners to co-design and co-deliver education and skills training in innovative new ways, better suited to the needs of employers and workers in the knowledge economy.”

Frofessor Hugh Brady, Vice-Chancellor and President of the University of Bristol, said: “We have been given a once-in-a-lifetime opportunity to reimagine the future of our University as one of the world’s great civic universities while also transforming a key site at the heart of our city.

“Our new campus is very much a work in progress and we would welcome people’s feedback, on everything from education provision, research and innovation to community engagement and transport links.  We don’t know exactly what it will look like yet, but we do know that we want it to feel welcoming to everyone and to be a place for the whole city to learn, explore and enjoy.”

Although designs for the campus are in their infancy and will be informed by the outcome of the consultation, there are ambitions to develop landmark buildings and public spaces which will provide a fitting welcome to those travelling into Bristol.

Fully developed, the Enterprise Zone has the potential to attract over 17,000 jobs over its 25-year lifetime and add a further £100 million a year to the city’s economy.

A second round of consultation will follow in September before an outline planning application is submitted to Bristol City Council later in the year. Applications for individual buildings will follow, with further consultation in 2018/19, when building work is expected to start. The new campus is planned to open for 2021, says Cliffe.

Filed under: News 

Startup Zeetta Networks has won a contract worth £1.8m to build a large-scale demonstrator of its Software Defined Networking (SDN) technology at the Ashton Gate sports stadium in Bristol, writes Nick Flaherty at TechSpark’s High Tech channel.

The contract from InnovateUK follows trials at the stadium last year and will see Zeetta’s NetOS software deployed throughout the stadium. Zeetta will build new business applications on top of the NetOS platform for the wide range of events at Ashton Gate alongside third-party providers, turning the stadium into a test lab for big data applications

The project has broader implications for Zeetta as NetOS can be applied to shopping centres, hospitals, airports and other venues with complex operating networks.

The project will connect tens of thousands of devices including mobile phones, cash tills, turnstiles,  display screens, air conditioning and heating as well as sensors and building management systems, all with software that is easy to set up, monitor and reconfigure in real time. Zeetta, a smart city spin-off from the University of Bristol, will also develop a programmable platform for new services by extracting data analytics from the network for new software apps.

“Stadia and other large venues, across the UK and beyond, are challenged by their consumer need for more data and faster response time particularly as they scale up their activities into new business areas,” said Vassilis Seferidis, CEO of Zeetta Networks. “This first-of-a-kind deployment forms a key part of our business plan by demonstrating our technological capabilities and the resulting commercial benefits for our customers.”

“We’ve been working with Zeetta Networks for the last 12 months and it is exciting to see the potential uses of this system unfold,” said Martin Griffiths, chairman of Ashton Gate. “Sports stadia across the globe struggle with connectivity and real-time evaluation of data. I believe we are just scratching the surface of what this NetOS platform can deliver and look forward to seeing its implementation over the coming year. Using Ashton Gate Stadium as a live test lab I’m confident that we will be able to drive greater fan engagement along with significant returns to our businesses.”

Bristol researchers help build 5G wireless network

June 2, 2017 by · Leave a Comment
Filed under: News 

Bristol researchers are at the heart of a £6m project developing the next generation of optical networks to support 5G wireless technology.

The three-year METRO-HAUL project includes software defined networking (SDN) startup Zeetta Networks and the University of Bristol’s High Performance Networking group in the Department of Engineering alongside 19 other organisations around Europe. These include operators BT, Telecom Italia, and 02’s Spanish owner Telefonica, equipment makers Ericsson and Nokia, and German research group Fraunhofer Institute.

The next generation 5G technology is currently being developed to provide up to 1Gbit/s of download speed, but that will need to be supported by higher performance optical networks. The aim of the project is to design and build smart, cost-effective, optical systems for urban areas that can support increased traffic coming from all kinds of 5G links, whether these are base stations, small cells or connections from the Internet of Things (IoT).

By 2019 the project will build a 5G network with a range of services in a test-bed, and the software developed will be released as a public repository while the project will actively participate in the standardisation of 5G, promoting the tested solutions to the wider industry.

“We are very proud to have played a key role in this successful EU funding bid and to be collaborating with such a group of leading researchers, telecoms operators, innovative SMEs, and influencers in 5G,” says Vassilis Seferidis, CEO of Zeetta Networks. “This project scored very highly with the judging panel recognising its importance and the huge implications it brings to the telecoms industry and the verticals they support. It is another validation of Zeetta’s growing global profile and positions our software-designed networking technology as a highly innovative solution enabling programmability in both current and future networks.”

This is just one of several 5G projects that include technology companies from the region. For example, Blu Wireless Technology is part of the XHaul project that is looking at other ways to provide the links that will be needed and recently hosted all the researchers involved to collaborate in Bristol.
