HOW IS INNOVATIVE COMPETITIVENESS CREATED? an incredibly expansive area of business. Smart solutions, with capabilities for building intelligence into products and systems, are rapidly EDITORIAL growing. The conditions for creating new innovations have never been greater than they are now. We can also be quite certain that the rate of development will continue to increase, which means that next year, and the year after that, we’ll be able to make the same statement. WE’RE WORKING IN

For a country to transform these opportunities into competitiveness, a number of basic factors must be in place. We need good schools that nurture children’s natural curiosity and that impart knowledge and inspiration. This improves the conditions for attracting as many applicants as possible to our engineering schools and maintaining high standards in academic programs and research projects, which in turn generates a good recruiting base for businesses as well as expertise that can be strengthened and renewed. Companies also need a good operating environment, where rules and regulations are reasonable and fair. But additionally, as icing on the cake, we have to develop an innovative culture. In our complex world in continuous change, we need specialization as well as openness and responsiveness. We must specialize so that we can sufficiently immerse ourselves in the technology to achieve world class solutions. If we don’t listen to the needs of the market, we won’t find the right solutions. And if we’re not open to new and perhaps unconventional ways of looking at things, our ideas can be held back by outdated approaches. An easy and ingenious recipe for success is collaboration. In a more open collaborative atmosphere, with a thoroughly developed ecosystem, a brilliant idea can progress through the value chain and be refined into a successful innovation, ready for market. Here we can contribute with what we’re best at. This is how successful solutions are created in response to problems, challenges and needs. Solutions that make our world a better place to live. In this issue of Tech Trends, you can read about some excellent examples of just how much can be achieved through successful collaboration. ×

THERMAL CAMERAS – FROM IDEA TO FINISHED PRODUCT FLIR Systems’ goal is to develop thermal cameras and IR technology that improve and even save people’s lives. The products used by businesses and consumers all over the world are manufactured in Täby, Sweden. THE COMPANY PRODUCED its first thermal

camera more than 40 years ago, then under the name AGA Infrared Systems. More than 400 people now work at FLIR Systems’ new facilities in Täby, outside Stockholm. All operations – development, testing, verification, production and calibration – are gathered under the same roof. “We develop everything from simpler thermal cameras that can be used with smartphones, to advanced systems for research and development,” says Joakim Fjäder, who leads FLIR’s FPGA team. “The products are used in for example, crime prevention, energy saving, medicine and environmental protection.” As the prices of thermal cameras fall, the technology is becoming more accessible for both businesses and consumers. At the same time, customers expect the same performance and graphics experiences as they have in their smartphones, which puts pressure on product development.

“I’m proud that we’ve succeeded in achieving such a high level of imaging,” says Joakim. “There are relatively few of us developers behind these advanced products, but it works thanks to our experience and passion for what we do.” BASED ON FPGA TECHNOLOGY

FLIR uses FPGA circuits in their cameras and this is also what Joakim and his development team work with. An FPGA – field-programmable gate array – is a digital, integrated circuit that is programmed after manufacture to handle a specific function. The same circuit can be used for different tasks depending on how it is coded. In an FPGA circuit, all blocks can be run in parallel and its architecture provides high calculation capacity in relation to power consumption. In FLIR’s case, energy consumption and high data rates are important parameters. “Because our cameras measure and visualize heat, we have to minimize

self-heating,” Joakim explains. “At the same time, it’s essential to achieve high calculation speed as well as good battery life for systems that are handheld. FPGA programming is like putting together a complicated puzzle and it requires experience and thorough understanding of how the code is translated to FPGA primitives.” PREVAS STRENGTHENS THE TEAM

The FPGA team consists of ten developers – seven are employed at FLIR, one is a consultant working on-site at FLIR and two are working in Poland at the site of a collaborative partner. Prevas consultant Johan Degerman has been on the team since 2015. “FLIR’s thermal cameras incorporate incredibly exciting technology and FPGA plays a key role in the products,” says Johan. “Because product development and production are at the same location, we get immediate feedback on what we’ve done and we can make quick decisions. This makes the job interesting, dynamic and also lots of fun.” Johan, who has a degree in computer science from Umeå University, has worked at several consulting firms and been involved in development projects

for many different customers. He enjoys working at FLIR, and not just because of the interesting technology the company develops. “The working environment is relaxed and it’s easy to reach agreement with my colleagues,” says Johan. “Despite the high level of expertise, the company culture is free from prestige conflicts and you always feel like you can ask questions and speak your mind. I also feel that people want to hear my ideas and opinions, which isn’t always the case as a consultant.” The members of the FPGA team have broad collective expertise, encompassing among other things imaging, memory management and electrical interfaces. FLIR has worked with Prevas for several years to complement its own expertise. Besides FPGA, Prevas also provides expertise in electronics, mechanics, software and PCB layout. “When we’ve needed external resources, Prevas has always been able to provide truly good candidates. Senior experts with the right experience and skills,” says Joakim. “Many fulfill the same formal requirements, but the ability to quickly come up to speed in our operations has been decisive for us.”


General technical development and digitalization in industry and society are creating new application areas for FLIR’s products. An example is drones equipped with thermal cameras to monitor crops, inspect solar panels and obtain information on the spread of fires. In industry, thermal cameras are used in quality control and monitoring to avoid downtime, for example. “We develop market-leading products in a technical area where we are constantly discovering new opportunities. It feels especially good that we do everything here in Sweden, from preliminary studies to production. I can follow development from an idea to a finished product that I can hold in my hand,” says Joakim in closing. ×

WHEN TECHNOLOGY SAVES LIVES When Ambu decided to re-design their Ambu®Man resuscitation training manikin, it was Prevas they turned to for help. DEATH FROM SUDDEN CARDIAC ARREST

accounts for about 15% of all deaths in Western countries. With the worldwide increase in obesity and sedentary lifestyles, this figure is only likely to increase. A substantial amount of lives can be saved if more people are familiar with Cardio Pulmonary Resuscitation (CPR) techniques, and the use of high fidelity training manikins is key to achieving this.

For almost 80 years, Ambu, a company of over 2300 employees worldwide, has been dedicated to improving patient safety and saving lives through innovative

technology in the areas of Anaesthesia, Patient Monitoring & Diagnostics, and Emergency Care. The Ambu®Man training manikin, has over the years played a key part in training medical professionals, emergency services and the general public in the skills of resuscitation. As Fabian Sachs, Senior Corporate Product Manager at Ambu explains, the time had however come for a complete update, “we felt that with the current advances in mobile and sensor technology, along with changing medical guidelines, the time was right for the next generation of Ambu®Man”.

With a background as a street medic, nurse and a degree in medical engineering, Fabian has first-hand experience in knowing that technology can make a product more user friendly and save lives. “I know from my own past how important CPR-training is for the possibility to save lives in any environment. With the new Ambu®Man, we wanted a self-contained product that could be controlled from any available tablet, smartphone or computer, without the user having to install a dedicated app. It should also be robust, expandable and with exceptional battery life, enabling


long duration training scenarios to be performed”. It was Prevas with their expertise in embedded systems, that Ambu turned to for help. Ambu and Prevas’ engineers were quickly able to solidify the requirements and start prototyping solutions. ADVANCED TECHNOLOGY TO THE RESCUE

“Fabian’s requirements really pushed the state-of-the-art in what had previously been done with Single Page Web Apps for embedded systems”, says Christian Ward, Senior Product Manager at Prevas, “indeed, we believe this is the first time such a sophisticated, responsive and highly dynamic Web App has been used to control an embedded system. The power of modern web browsers allows us not only to offer a native app-like experience without downloading any dedicated software, but it also allows some of the data processing an embedded system would typically do, to be off-loaded to the user’s web browser”. Aside from the revolutionary user interface, the manikin also contains a multitude of sensors and actuators to enable the trainee’s resuscitation technique to be accurately evaluated. The sensors not only measure chest compression depth and ventilated air volume, but also for example, if the trainees have performed the compressions with their hands placed on exactly the right spot. The ability to simulate a carotid pulse and breathing sounds, whilst generating ECG waveforms that respond to high voltage defibrillations, enable highly realistic

training scenarios to be performed.

schedules”, says Christian Ward.

“Healthcare professionals, fire brigades and first aid trainers can set up realistic scenarios involving up to 6 manikins, allowing multiple casualty accidents to be simulated and practised”, says Fabian Sachs. “The instructor will be able to see the results from each of the trainees visualised in a single browser window and can instantly rate their technique, modifying the training session in real time. Without these manikins, it would have been impossible for the instructor to give this kind of feedback. The prelaunch field trials showed that people really like the new approach we have taken to the digital technology”.

“Together we have created a modular platform that not only brings resuscitation training right up to date, but also enables future enhancements via software updates – we are only scratching the surface of what soon will be possible”, says Fabian Sachs. ×


“We worked in a very close partnership with Prevas to ensure a high quality delivery on time. Together we set up realistic deadlines and had short communication paths, which allowed us to quickly solve any issues – the total development time was around 12 months, from our first discussions of the idea, to the commercial product announcement and market launch”, explains Fabian Sachs. “Developing a product containing precision sensors, an embedded control system with the ability to absorb kilovolt defibrillation pulses, whilst being physically rugged enough to allow training scenarios in extreme environments is no easy task, so the ability of our two teams to sit down and combine their different engineering expertise, allowed us to tackle problems together and maintain

HOW IT WORKS The product utilises the very latest mobile technologies running Prevas Industrial Linux (PIL), to create a powerful platform for the Web App control and user interfaces. The Web App interface enables training sessions to be controlled from any modern browser, without the need to download and install a dedicated app. A user merely connects to the manikin, for example via the WiFi access point it can create, and points their browser to the manikin’s homepage. The Single Page Web App built using the Angular framework, is loaded and automatically optimises itself to the screen size and rotation of the user’s device, displaying sophisticated real-time graphs and graphics that are dynamically generated and rendered in the browser, to give a native app like experience. At the same time, other nearby manikins are “discovered”, allowing the instructor to start and monitor multiple training sessions from the same user interface. A custom battery pack with built in charging and fuel gauge circuits gives over 15 hours run time, enabling accident scenarios that start on the top of the mountain and end up in the operating theatre, to be simulated and practised.

Bike helmet of the future The idea of an airbag for bike riders was studied in a degree project at Lund University. Development is now being conducted by the company Hövding with support from Prevas. The bike helmet has reached the market and independent tests are showing unprecedented protective capabilities. “THE GOAL WAS TO CREATE INVISIBLE PROTECTION FOR BIKE RIDERS, a product

designed to better match everyday clothing and that would hopefully attain the same performance as a bike helmet,” says Heino Wendelrup, lead developer at Hövding. “The result of our development efforts is a fantastic innovation that provides significantly better protection than a standard helmet.” The bike helmet from Hövding looks like a separate collar and works in about the same way as an airbag system for cars. The system consists of sensors – accelerometers and gyros – that constantly measure the rider’s movements. An algorithm that is “taught” with data from actual collisions and arranged accidents interprets the information from the sensors and makes decisions 200 times each second: trigger or don’t trigger. “When there’s a collision or fall, the helmet triggers in 0.1 seconds and forms a large protective enclosure that most closely resembles an air-filled integral helmet,” Heino explains. “The rider’s neck is immobilized and the head is protected.” UP TO EIGHT TIMES BETTER PROTECTION

A test conducted by the insurance company Folksam shows that the Hövding helmet has three times better impact absorbing capabilities than the best conventional bike helmet. Stanford University in California recently presented a study that clearly focuses on the medical effects, in other words, the level of protection various helmets provide against head injuries. The study shows that Hövding helmets provide up to eight times better protection against


concussions than conventional helmets. “The protection factor can be illustrated by an example in which a bike rider is travelling at 25 kilometers per hour,” says Heino. “In the event of a collision, the risk for serious head injury is 90 percent if the rider is using a conventional helmet. With a Hövding helmet, the risk decreases to just 2 percent.” Hövding helmets also dampen rotation in a fall since the larger physical protection absorbs forces in all directions. Less rotation means lessserious injuries but this aspect has not yet been included in independent testing of bike helmets. AN IMPORTANT PROJECT FOR PREVAS

Prevas was engaged to assist in development of the Hövding helmet in 2012. Three experienced engineers in electronics, test systems and mechanics were involved in development. From Prevas’ side, the assignment has been coordinated by regional manager Patrick Buschow. “It’s very stimulating to be along and help our client on this journey,” says Patrick. “Both the actual product and the commercial coupling are of interest to us and we do all we can so that their operations are as profitable and successful as possible.” The technology in the Hövding helmet is based on standard components, such as those found in smartphones and TV gaming controllers. Prevas’ job is to improve the system, in among other ways by optimizing the circuit board and software. The focus is on new adding functions, while at the same time, making the product

lighter, more pliant, more stable, more user friendly and less complicated to manufacture. “For us, the project has been a little different since we’re usually engaged in development projects for industry,” says Patrick. “As an exciting innovation for the consumer market, Hövding really stands out among our references. The work has been educational and collaboration with the client has gone really well throughout the entire project.” “We chose Prevas because they have extensive experience from product development and multidisciplinary collaboration,” says Heino. “They’ve shown considerable understanding of our situation as a smaller development company and they’re comfortable with working in an innovative environment where the frameworks aren’t always fixed. We value Prevas’ expertise and working together with them as an active partner.” INCREASED AWARENESS A KEY

For the time being, not many are aware of the Hövding helmet beyond the Swedish market. Increasing awareness of the product and the safety aspects – among both consumers and retailers – is therefore an important challenge for the continued development of the company. ×
