Benefits of Using an Inverter Generator
Each day, new changes are being made when it comes to the generator technology. It is no longer the same when people were comfortable with the gasoline engine generators as they are now becoming obsolete with due to the new technological enhancement. The use of the new inverter generators has been on the rise due to the many advantages that people have realized. For instance, even though the inverter generators are a little more expensive than the traditional ones, they have changed the way the generator makes power. The following are other advantages that you will realize when you get to use the new technology generator at your home.
The one thing that you need to remember is that the inverter generator is of less weight than the traditional ones. It, therefore, means that even for those people who carry generators around, it will be much simpler for them to carry the new inverter generator. All you need to ensure is that you have identified the right place where you can purchase.
The other benefit is that the inverter generator is quieter in comparison to the traditional generators. The new technology does not produce much noise. You can agree that with the traditional generator, it works under the same high RPM even when the load is little, and it will make noise all through and all the same. When you do not need much noise in your surroundings, it is important to consider going for the inverter generator.
The other thing that as a buyer you need to know is that you will be using minimal gasoline to power the inverter generator. As said earlier, the new technology is able to monitor the load so that it adjusts the speed automatically. If the load … Read More..Read More →

Master of Embedded and Cyber-Physical Systems
The graduate program in Embedded and Cyber-Physical Systems is administered by faculty from two academic units: the Donald Bren School of Information and Computer Sciences, and the Henry Samueli School of Engineering. The program offers the Master of Embedded and Cyber-Physical Systems.
Embedded systems are now entrenched into almost every aspect of our daily life, rivaling in ubiquity anything that exists today. Currently, we have tools to help us design embedded systems, making good use of available technologies at a variety of levels and scales, from hardware to interface, operating system, middleware, and software. Cyber-Physical Systems (CPS) are systems-of-systems that tightly couple their cyber (i.e. computation, communication, and control), and physical components (sensing and actuation) in the context of applications such as (but not limited to): automotive and transportation, manufacturing, power distribution grid, medical and healthcare, robotics, civil infrastructure, avionics, etc.
Thus, these Cyber-Physical Systems marry knowledge from the fields of embedded systems, networking, sensors, real-time systems, and control, as well as domain-specific knowledge, to realize systems that are of untapped complexity and scale. The Master of Embedded and Cyber-Physical Systems (MECPS) program’s goal is to train students in the foundation, skills, and practices of embedded and cyber-physical systems design, optimization, and evaluation. MECPS draws primarily from Computer Science and from Engineering.
Applicants for the MECPS Program apply through the Office of Graduate Division and indicate on their applications their interest in the program. Applicants are expected to hold a bachelor’s degree in Computer Engineering, Computer Science, or Electrical Engineering.
Students from other disciplines may be considered for admission if they have sufficient background in the basics of embedded systems. Applicants are evaluated on the basis of their prior academic record and their potential for carrying out graduate-level work as demonstrated in submitted application materials. These materials include official university transcripts, letters of recommendation, and Statement of Purpose.
Of particular interest are students whose background is in one of the target application areas of CPS (e.g. mechanical engineering, civil, biomedical, etc.). Students with some industry experience will be considered favorably, especially if their experience is relevant to the areas emphasized by CPS. An admissions committee composed of senate faculty members evaluates the applicant files and makes admissions decisions based on the overall file presented by the student. Overall, students are admitted using criteria similar to those used in traditional M.S. degrees from relevant departments (Electrical Engineering and Computer Science and Computer Science).

Nvidia has purportedly announced that holders of the original Shield TV set-top box can now download Software Upgrade v5.0. The new download is a free over-the-air update which reportedly also boosts existing gaming capabilities alongside the viewing upgrades.
Nvidia CES 2017 announcement: Nvidia announces 4K Shield TV, cloud-based GeForce Now gaming service for PC and Mac.
Nvidia has purportedly announced that holders of the original Shield TV set-top box can now download Software Upgrade v5.0. The new download is a free over-the-air update which reportedly also boosts existing gaming capabilities alongside the viewing upgrades. The Nvidia Shield TV is said to be acclaimed for the additions it has taken to the somewhat neglected Android TV platform.
According to reports, the platform update also brings the older Shield TV unit to speed up with an upgrade to Android 7.0 Nougat. The update apparently adds everything found on the latest Shield TV unit launched early this year, such as 4K HDR streaming video support in Amazon Video, Netflix, YouTube, Google Play Movies, VUDU and many more.
There is apparently ample support also for upgraded GeForce Now game streaming. On the other hand, a new Nvidia Games app brings together all the available gaming sources, such as GeForce Now, GameStream and Android native games.
It is also reported that original Shield TVs can also be used as a smart home device in the future once the features are activated and probably with future software updates. It is also rumored that a new Shield TV comes with a controller that features a built-in ambient microphone, an addition that will be required for using voice recognition with Google Assistant. The microphones accordingly can be placed at various plugs throughout a house.
The new Shield apparently looks almost identical to its predecessor, but the controller has slightly longer handles. Performance wise, it is rumored that Nvidia claims it has three times the performance of any other streaming device on the market.
It is said to have digital assistant features, with a software update for SmartThings' smart home hub that is probably upcoming in the future. Accordingly, the only slight concern is that there is still no apparent sign of a follow-up to the Nvidia Shield tablet.

The following are some projects Vitech has completed or is currently working on:
The hydro-acoustics program operated by the Pacific Salmon Commission provides estimates of the daily passage of salmon at a site located near Mission B.C. The knowledge of species composition is critical in the estimation of sockeye and pink abundance for the Fraser River Salmon Fisheries Management. This knowledge has historically been derived from test fishing data, and may be subject to significant bias. Recent applications of the high-resolution sonar system (DIDSON) at Mission and upstream locations have provided a unique opportunity to examine this challenging problem.Vitech was funded by the Pacific Salmon Commission to conduct a feasibility study of deriving species composition estimation from DIDSON imaging sonar data. The project has been accomplished and the result shows considerable promise (Email us for a copy of the report).
The Institute of Ocean Sciences, Department of Fisheries and Oceans of Canada, deployed an intermediate range sonar system at at Chatham Point in southern Johnstone Strait of British Columbia, to monitor returning salmon with a goal to estimate the abundance of salmon passing through the area. The system can continuously collect acoustic data during the salmon season. Vitech was contracted to conduct numerical analysis of the acoustic environment in the observation area, and develop tracking algorithms and software, allowing automatic analysis of large database and estimation of fish abundance. The first phase of the project has been completed.
The Pacific Salmon Commission has been using split-beam sonar systems at a site located near Mission B.C, to provide estimates of the daily passage of salmon. This is a continuous program with the need to handle a large amount of data each day in the season. Vitech was contracted to develop a software system that allows users to visualize and analyze split-beam sonar data to derive an estimate of daily passage of salmon. The software system performs automatic tracking of sonar data and allows users to filter out unwanted tracks using a pattern recognition technique.The system has played a key role in the hydroacoustics program.

The SPRI Golf Sports Medicine Program includes the use of leading-edge biomotion technology, golf coaching and physical assessments. Below, learn more about the technology used for this innovative program:
SPRI’s Biomotion Laboratory is equipped with some of the world’s most advanced technology, including a 20-camera, 12-megapixel 1100 frames-per-second video motion analysis system, Bertec force-sensing platforms (embedded in the floor) and wireless electromyographic sensors for analyzing muscle function. This equipment provides detailed measurement of the kinematics (motion) and kinetics (forces) that generate movement. Combined with our advanced analysis software, the lab can comprehensively assess an individual’s biomechanical profile for nearly any activity or sport.
In addition to general assessments of movement quality, the lab software can provide detailed, sport-specific analyses. A specialized Qualisys module specifically assesses the biomechanics of the golf swing. This software provides an in-depth view into how an individual’s movement may impact their golf swing, providing detailed metrics on swing components such as the kinematic chain, ground reaction force, center of pressure and club motion. Applications for these technologies go well beyond simply helping the average golfer improve his or her game. Our unique, multidisciplinary team (combining orthopaedic biomechanics experts in the Biomotion lab, the leading orthopaedic surgeons and athletic trainers of The Steadman Clinic, the rehabilitation specialists from Howard Head Sports Medicine and a PGA Master Professional) can use this comprehensive data to guide those recovering from injury or with an underlying orthopaedic condition to improve their physical function and optimize their performance.
The Biomotion technology is complemented by a cutting-edge golf simulator from Foresight Sports. This simulator includes the most advanced and precise launch monitor (the GC Quad), which utilizes infrared object tracking and high-speed, high-resolution camera-based technology to precisely measure every aspect of club head and ball launch performance. By capturing thousands of images per second, building a virtual 3D model and then analyzing a multitude of data components, the technology creates the most accurate and complete picture of ball and club head performance, delivered in nearly real time.
The biomotion measurements can be performed within the golf simulator, providing a unique linkage between the whole-body motion assessment and the resulting ball trajectory. The golf pro and client can immediately see the real-world results of changes in swing biomechanics, in terms of both distance and accuracy. This unique combination of technologies ensures that individuals get the full picture of their golf performance, from inside out.
Add the unparalleled graphic technology and simulation experience to the most advanced biomechanical assessments available, and participants of the SPRI Golf Sports Medicine Program will enjoy a one-of-a-kind experience, supported by state-of-the-art technology backed by a legacy of research.
The Titleist Performance Institute-certified (TPI-C) physical therapists and golf specialists at Howard Head Sports Medicine (HHSM) conduct a full physical screen that includes top-of-the-line Keiser pneumatic machines to identify strengths and limitations. This helps determine how participants’ bodies affect their golf performance.
HHSM TPI-C therapists are musculoskeletal experts who are dedicated to understanding and solving for body limitations, dysfunction and prior injuries. The goal of the physical assessment at HHSM is to give participants actionable ways to improve speed, strength, balance and movement patterns while preventing injury.

Some patients with severe brain injury show short-term neurological improvements, such as recovery of consciousness, motor function, or speech after administering zolpidem, a GABA receptor agonist. The working mechanism of this paradoxical phenomenon remains unknown. In this study, Arnst and his colleagues used electroencephalography (EEG) and magnetoencephalography (MEG) to investigate a spectacular zolpidem-induced awakening, including the recovery of functional communication and the ability to walk in a patient with severe hypoxic-ischemic brain injury.
They showed that cognitive deficits, speech loss, and motor impairments after severe brain injury are associated with stronger beta band connectivity throughout the brain and suggest that neurological recovery after zolpidem occurs with the restoration of beta band connectivity. This exploratory work proposes an essential role for beta rhythms in goal-directed behavior and cognition. It advocates further fundamental and clinical research on the role of increased beta band connectivity in the development of neurological deficits after severe brain injury.

FUSES - MV HV MEDIUM VOLTAGE & HIGH VOLTAGE 11KV-33KV
Fuses are based on the type of circuit they are used in i.e. AC Fuses and DC Fuses. Again, AC Fuses are divided in to High Voltage (HV) Fuses and Low Voltage (LV) Fuses. High Voltage (HV) AC Fuses are used for voltages above 1000V and Low Voltage (LV) AC Fuses are used for voltages less than 1000V.


New Technology Allows ATC To Track Aircraft In Mountainous Areas That Are Outside Radar Coverage
– The Federal Aviation Administration (FAA) and Colorado Department of Transportation (CDOT) announced the activation of new NextGen technology that will help pilots address inclement weather around Montrose Regional Airport in western Colorado.
The technology, known as Wide Area Multilateration (WAM), improves safety and efficiency by allowing air traffic controllers to track aircraft in mountainous areas that are outside radar coverage.
“Safety is our highest priority, and this is an excellent example of state and federal governments working together to not only improve safety and efficiency, but also provide immediate economic benefits,” said U.S. Transportation Secretary Ray LaHood. “The new technology will help local businesses that depend on (...) aviation.”
The FAA and State of Colorado expect to complete the project by deploying WAM around Durango, Gunnison and Telluride in summer 2013.
“This system will allow pilots to fly search and rescue missions in weather conditions that would have previously kept them grounded,” said Acting FAA Administrator Michael Huerta. “It also will support Colorado’s tourism by enabling pilots to land in conditions that previously caused diversions or flight delays.”
WAM is a NextGen technology that tracks aircraft using a network of small sensors deployed in remote areas. Aircraft transponders receive and send back signals to these sensors. System computers immediately analyze those signals and determine the aircraft’s precise location.
The NextGen program uses technology to create a modern, satellite-based air traffic control system, transforming the national airspace to make it safer and more efficient.

News release about "IMS 2018 in Philadelphia"
The Secret of Junkosha revealed at IMS 2018 with the launch of two new millimetre wave interconnects for the 5G generation
IMS 2018 stand number: 2240
Friday June 8th 2018 at 09:00 GMT
As engineers respond to the challenge of millimetre waves to meet the demands of a 5G age; the performance of interconnects has come under close scrutiny. The need for phase stability is considered vital across R&D and Quality functions responsible for the development and maintenance of high-frequency networks that are at the core of increasingly sophisticated systems. Cables have a reputation as a weak link in test equipment like Vector Network Analyzers (VNAs) where instances of flexure and movement have an impact on the accuracy of results, which is accentuated as frequencies increase. At the forthcoming IMS event (June 10-15, Philadelphia, USA) interconnect pioneers Junkosha aim to challenge this view. Announcing the launch of a new range, the Japanese company will showcase an ultra-phase stable interconnect that endures in the field and the laboratory.
With its next generation MWX051 and MWX061 interconnects, Junkosha has designed mmWave cabling solutions up to 67 GHz to meet the higher frequency demands of tomorrow’s 5G networks. Available with ruggedized NMD connector assemblies to deliver reliable and robust connections to the VNA, these new interconnect solutions have been created to withstand the most rigorous of testing environments for periods of approximately three and a half years(*) . Featuring characteristics including high tensile strength, a low dielectric constant and high flex life thanks to Junkosha’s precision engineered expanded-PTFE wrapping technology, these new interconnects will test engineers’ resolve to stick with lower quality, lower cost alternatives.
“The demand for mmWave frequencies is no longer the preserve of military and research applications”, explains Joe Rowan, President and CEO of USA and Europe for Junkosha. “5G and high-speed data applications are now driving innovation. For those familiar with the ‘Secret of Junkosha’, it will be no surprise that we are at the forefront of the development of high frequency interconnects. Our expertise and pedigree in expanded-PTFE tape wrapping has enabled us to deliver a flexible phase stable cable that endures.”
The IEEE MTT International Microwave Symposium (IMS) is the premier annual international meeting for technologists involved in all aspects of microwave theory and practice. It consists of over 600 exhibiting companies that represent state-of-the-art technologies including materials, devices, components, and subsystems, as well as design and simulation software and test and measurement equipment. In addition, it comprises a full week of events including technical paper presentations, workshops and tutorials.

The bold goal of High Energy Physics is to understand the characteristics of the fundamental particles and forces that compose the universe; it strives to understand the ultimate nature of everything. High Energy Physics has made great progress in developing the Standard Model of particle physics, culminating with the discovery of the Higgs boson in 2012, a particle predicted by the Standard Model that gives matter its mass. Despite the great successes of the Standard Model, it is known to be incomplete. Of particular interest is the possibility of extending the Standard Model to incorporate dark matter. Compelling astronomical evidence points to the existence of dark matter, material that does not interact with photons and therefore is non-luminous, yet which constitutes 85% of all the matter in the universe. If this dark matter is composed of as-yet undetected subatomic particles, it will take a new generation of particle detectors to discover them.
This FIRE stream takes you on a journey to help create the next generation of particle detectors, ones that will be used by scientists all over the world to learn more about the basic building blocks of matter and the forces that govern their interactions. Along the way, you will learn fundamental physics as well as the computational and research skills needed to contribute to this exciting field. The only background needed for this stream is a high school physics course.
You will learn to optimize subatomic particle detector elements through calculation and simulation, investigate how detector design will impact data analysis, work with large data sets, and work in a team to organize, plan, execute, and present your research. Completing this FIRE stream should position you to compete effectively for Research Experiences for Undergraduates at Fermilab, CERN, and other institutions and government labs. The research skills you learn will be useful in many other fields dealing with large data sets, such as astrophysics, climatology, computer science, engineering, and economics.

The Condensed Matter Physics
The Condensed Matter Physics (CMP) is the largest research field in Physics, with 40% of the total research in Physics being generated by the CMP area. Within the last 20 years, 8 Nobel Prizes were awarded for discoveries in CMP, which make 40% of all Nobel Prizes in Physics.
The knowledge generated by CMP represents the foundations of modern electronics and has enabled breakthroughs in other areas of Physics. LEDs, semiconductor lasers, laser amplifiers, optical fibres, high-temperature superconductors, solid-state hard drives, superconducting qubits, integrated optics and optical microchips, etc… are based on discoveries by Condensed-Matter Physicists. Most of these discoveries led to Nobel Prizes. The recent experimental discovery of gravitational waves would not have been possible if CMP physicists had not discovered semiconductor heterostructures used in modern lasers. Quantum computers are based on either the superconductivity effect in metals or optical properties of solids. The accelerators of the Large Hadron Collider uses superconducting electromagnets to steer the particles.
Magnetism is a research area that belongs to Condensed Matter Physics. The modern physical research in this area is focused on behaviour of magnetic objects with characteristic sizes in the nanometre range (1 nanometre (nm) is one millionth of millimetre). These objects may be thin layers (“films”) of magnetic metals or much more complicated advanced chemical compounds, such as single-crystal films of oxides of magnetic-atom species. The characteristic thicknesses of these magnetic films are on the order of 1 nm or below. A Nobel Prize in Physics was awarded for this work in 2007, because of an extreme importance of the research into thin magnetic films for applications. Indeed, the modern cloud information storage would have been hardly possible without the discovery of the magnetic tunnel junction for which the Nobel Prize was awarded.
A large interest also exists for the magnetic behaviour of more complicated objects, having all three dimensional sizes in the nanometre-range. Examples of these are magnetic nanodots and magnetic nanoparticles. Theoretical and experimental research shows that reducing the sizes of magnetic objects to this scale drastically changes their behaviour. Many applications of the magnetic properties of those objects in Electronics and Bio-Medicine have been proposed.
In addition, Magnetism is an effect of quantum nature, and the quantum origins of the effect currently attract more and more researchers with interest in Quantum Information and Quantum Computing to this field. Significant breakthroughs in this area have been achieved recently, and our group has contributed to the breakthroughs (more detail below).
Magnetic microstructure to study properties of spin waves. Charles Weiss fabricated it during his visit to Strasbourg University, France. Charles took this electron-microscope image while in Strasbourg. The scale bar in the image is 20 micrometre long. The finest details of the structure have sizes of several hundreds of nanometre.
The current focus of the Condensed Matter and Magnetism research group is waves and oscillations in solids. Solids support propagation of different waves – sound (phonons), light (photons), light-like excitations called plasmons and waves of magnetic nature called spin waves or magnons. The latter waves exist in magnetic solids. In addition, multiple natural resonances exist in solids, for example plasmonic, electron-spin and ferromagnetic (FMR) resonances. We study these excitations both theoretically and experimentally. Our focus is on magnetic solids.
Theory of spin waves
Spin wave excitations exist in the microwave frequency range (0.5 Gigahertz to 100 Gigahertz). This is the same frequency range, where radios of mobile phones and GPS navigation operate. Therefore, one large area of spin wave research is exploring possibilities of using their properties to build novel microwave signal-processing devices [4,5]. Furthermore, spin waves are also used as way of probing characterise magnetic materials and to extract their magnetic parameters . Exploiting spin waves in those applications requires an important input from theoreticians . Theoreticians are able to predict how spin waves propagate in magnetic nanostructures, how they scatter from natural and artificially introduced non-uniformities of the wave-guiding medium, and how these waves can be excited and detected.
Theoreticians are also interested in spin waves as one of the most nonlinear wave objects known to science. Our group are world-leading experts in the theory of spin waves, and our theoretical papers on that matter are highly cited. Furthermore, we are constantly invited by world-leading experimental groups in the field to provide them with a theoretical explanation of their experimental data. This often requires constructing a new theory based on a theoretical approach that has never been exploited before by the spin-wave community . Our recent theoretical predictions include the use of spin waves in Quantum Information  and Quantum Computing . We have also built a theoretical model of the operation of a spin-wave based physical reservoir computer, which is a special type of a neural network.
Quantum Information, Quantum Computing and Artificial Neural networks based on magnons (experiment and theory)
Our recent discoveries include suggestions of using magnons in Quantum Information and Quantum Computing [12,13] and in artificial neural networks. Our latest proposal is a neural network called physical reservoir [6,9], which is based on very exciting Physics of Nonlinear Waves on the one hand. On the other hand, it is based on wave excitations of magnetic nature (magnons) in thin magnetic films. Therefore, we called this concept “Magnonic Reservoir Computer”. who is one of the proposers of this pioneering concept, was offered a postdoc at Oxford University, even before he started writing up his thesis.
Physics of nonlinear waves (theory and experiment)
The concepts of solitons (or solitary waves) is an important result of the physics of nonlinear waves. One example of a solitary wave is the tsunami wave. Theoretically, it is governed by the same equation as a wave in a wave pool. Spin waves in thin magnetic films are one more model medium to study solitary waves and other nonlinear effects, and you can do it on a desktop and without getting wet. Our group has contributed to this field significantly both theoretically and experimentally. One very interesting theoretical result we obtained is shown in the figure to the right.
A 3D visualisation of our theoretical prediction that spin wave bullets collapse via irradiation of caustic waves from them. The large peak in the figure is the spin-wave bullet. It is moving into the page. On its way, it irradiates two narrow beams backwards. The angle of 64 degrees between the beams is very specific and affected by the Doppler Effect, because the bullet speed is very high – about 2.5 km/s. The bullet loses its energy through this process and will eventually die, once it has run out of energy.
Magnetic approaches to Green Energy (experiment)
We have found that magnetism of some magnetic films that contain palladium metal responds strongly to the presence of hydrogen gas in the film environment. Since then we have been studying this interesting physical effect in detail [1,2,8,10,11]. Now this project is sponsored by local WA industry. The ultimate goal of the project is to develop an efficient hydrogen gas sensor for the hydrogen energy sector and eco-friendly automotive industry.
Applications of magnetic nanomaterials in Bio-Medicine
(experiment and numerical modelling)
We also look at the possibility to employ the FMR response of magnetic nanostructures as a physical principle for a sensor of magnetic nanoparticles. The nanoparticles are used in Microbiology and Medicine to detect anti-bodies that are produced by human bodies in response to infectious diseases (e.g. COVID) and tumours. In this way, the problem of diagnosing those conditions can be reduced to detecting nanoparticles introduced into a solution that contains a body liquid, e.g. blood. In our work, we strive to develop a new method of nanoparticle detection that employs magnetic properties of nanoparticles.
In order to efficiently detect a magnetic nanoparticle, the detector must have sizes that are also on the nanometre scale. Our discovery was that magnetic nanostructures called “anti-dots” are excellent candidates for the detectors. Anti-dots represent an array of nanoholes in a continuous magnetic film. We found that the FMR response of these nanomaterials is strongly affected by the tiny magnetic fields the nanoparticles create around them.
An array of holes (anti-dots) drilled in a thin layer of magnetic metal by Reyne Dowling. The hole diameter is about 300 nm. Reyne used a Focused Ion Beam setup at UWA’s Microscopy Centre (CMCA) to drill the holes. The small white objects with irregular shapes in the figure are magnetic nanoparticles captured by the nanostructure. Reyne took this electron microspore image at UWA’s Microscopy Centre (CMCA)
Design, fabrication and characterisation of magnetic materials
We have designed and fabricated a number of advanced magnetic materials. To fabricate them we use the clean room of the WA Node of the Australian National Fabrication Facility that is located on the UWA campus . In addition, we have a magnetron sputtering machine in our lab, and many films and multilayers we fabricated were made with this machine .
We use a number of experimental tools available in our lab to characterise these materials and ones fabricated for us by overseas-based collaborators. The tools include several FMR setups, a microscopic microwave probe based setup to investigate the propagation of spin waves on the micron and sub-micron scales, and a Magneto-Optical Kerr Effect setup.
We also employ neutron and X-ray beams to investigate our films. To this end, we travel to the neutron scattering facility of the Australian Nuclear Science and Technology Organisation (ANSTO), located in Sydney. Our group pioneered combining neutron studies with FMR by developing an FMR setup that can operate directly on the neutron beam line . In the photo to the left, Mikhail is loading a magnetic film sample into the sample holder of ANSTO’s Platypus instrument. The sample holder actually represents an FMR fixture that allows taking FMR and polarised-neutron reflectivity measurements simultaneously.

WHAT WE DO
This is the practice of using a laser beam to engrave on the targeted plastic surfaces. The process can be very technical and complex but very precise with engravings. Laser etching is widely used in telecommunications products such as handphone keypads, automotive power switch buttons, central console panels and audio products.
Laser marking technology creates lasting marks. With great precision, the laser can engrave, etch, anneal, or discolour surfaces. These marks are permanent, and you can easily read or scan them on any surface. As a result, this marking process is ideal for operations where permanency and accuracy are critical.

Nowadays, children everywhere spend more than 3 to 4 hrs. on digital devices like TV, computer and mobile.
These digital tools emit blue light which is harmful to kid’s eyes.
Light is made up of electromagnetic particles that travel in waves. These waves emit energy, which has range in length and strength.
The shorter the wavelength, higher the energy. The length of the wave is measured in nanometers (nm), with 1 nanometer equalling 1 billionth of a meter.
Blue Light has a very short wavelength so produces a higher amount of energy. Studies suggest that, over the time, exposure to blue Light could cause serious long-term damage to eyes.
Blue Light has a wavelength of between 380nm and 500nm; making it one of the shortest, highest-energy wavelength.
Blue Light waves are among the shortest, Because they are shorter, these "Blue" wavelengths flicker more easily than longer, weaker wavelengths.
This kind of flickering creates a glare that can reduce visual contrast and affect sharpness and clarity.
This flickering and glaring may be one of the reasons for eyestrain, headaches, physical and mental fatigue caused by many hours of sitting in front of a computer screen or other electronic devices.
Our eye’s natural filters do not provide sufficient protection against blue Light rays from the sun, let alone the blue light emanating from these devices or from blue Light emitted from fluorescent-Light tubes.
Blue Light penetrates deeper into the eye and has the potential to damage retinal structures through photochemical and photo- oxidative reactions in the retinal pigment layer. Short term exposure of blue Light manifests eye fatigue, eye strain and headache whereas long- term exposure may lead to gradual loss of visual function.
Almost all visible blue Light passes through the cornea and lens and reaches the retina. This Light may affect vision and could prematurely age the eyes.
Blue Light from computer screens and digital devices can decrease contrast leading to digital eyestrain, fatigue, dry eyes. Bad Lighting or how you sit in front of the computer can cause eyestrain. Symptoms of eyestrain include sore or irritated eyes and difficulty in focusing.

On Friday 24th of September Professor Ton Koonen received a royal distinction “Ridder in the Orde van de Nederlandse Leeuw” during the symposium “Optical Networks – communication fabric of our society”, preceding his valedictory lecture “Light work(s)”.
Optical technologies are permeating all layers of communication networks, from optical fibre links crossing the oceans to fibre connections to every home, and are now at the verge of entering our homes too. Without these, the internet as we know it would not have existed, neither all the lifelines which are keeping our society together in times of society lockdowns.
This article is based on Prof. Ton Koonen’s valedictory lecture, it contains some parts of the lecture and its goal is to give a short overview of the evolution of optical communication technologies.
“At the end of my formal appointment of more than 20 years as a full-time professor at TU Eindhoven, I would like to take you on a sight-seeing journey through what happened over all these years and how happy I have been to contribute my piece parts.
Before TU/e, I was in industry for another 20 years, the last nine years of which I was already partly involved in academia as a part-time professor at the University of Twente. All these years have been dynamic and it has been a great pleasure to be involved in the incredibly fast-evolving world of optical communication from its early years onward. When you enjoy your work, it does not feel heavy, it feels ‘light’… Hence the title of my valedictory lecture, ‘Light work(s)’, where ‘light’ has a dual meaning: ‘light’ as an adjective to indicate that the work in this domain has been a real pleasure and ‘light’ as a noun to describe how light really is a very important vehicle which has enormous power to carry information and thus keep our society together… Communication by means of light has been my ‘Leitmotiv’ all these years. It has been my drive for even more than 42 years.
In my valedictory lecture, I would like to introduce you to the wonderful world of optical communication. I plan to highlight, in particular, how optical communication evolved from a technology which connects big entities, like cities and industrial parks, to a technology which is reaching out to individual users, to their homes and offices, and even inside these buildings in order to extend the information highway all the way up to your devices. Fibre-to-the-Home has been installed in many cities in the Netherlands and ever more homes are being connected. As a next step, fibre will also enter the home, preferably in combination with technologies for connecting your devices wirelessly.”
On the global scale
Figure 1: Optical fibre networks – the fabric of our information society.
Over the last five decades, a very fast evolution of optical fibre networks has taken place. Whereas fibre links originally started as a powerful alternative to copper-based long-distance links between cities, they have expanded their territory a lot: at one end spanning across the whole globe and at the other end penetrating end user’s homes; see Figure 1. There are many fibre-optic cables crossing the oceans, such as those bridging the Atlantic Ocean from Western Europe to the US east coast over some 6000 km and those across the Pacific Ocean from the US west coast to Japan via Hawaii over some 9000 km .
The optical fibre was invented in 1966 by Charles Kao together with George Hockham at STL laboratories in the UK. I once met Charles Kao at a conference banquet in Hong Kong; it was truly unique to meet the founder of fibre optics in person. Kao received a Nobel Prize only in 2009, unfortunately a bit too late as he was not in a good mental health anymore. At Corning, USA, Donald Keck, Peter Schultz, and Robert Maurer produced the first optical fibre in 1970, but it still had large losses of about 20 decibels(dB)/km. Since then, enormous progress has been made in the purification of fibre glasses and in the control of production processes. Nowadays, fibre losses are as low as 0.17 dB/km, allowing a reach of more than 100 km. With its tiny single-mode core diameter of only about 9 mm, the transmission capacity of a single fibre has grown immensely to beyond 1 Tbit/s (i.e. 1000 Gbit/s) per wavelength, with room for over 100 wavelengths in the 1.5 mm wavelength bands where fibre losses are lowest.
Single-mode optical fibre has much lower losses than coaxial copper cables and also much higher bandwidth, so no wonder that they have taken over in long-haul transmission links. But maybe the most impactful difference which optical fibre brings with respect to copper cables, is that fibre offers an extra dimension for the transmission of signals, namely the wavelength dimension. In a fibre, photons carry the information. These light particles have a wide range of colours and each colour can be a separate transport channel within the same fibre. The fibre thus actually becomes a multi-lane highway in which each lane offers tremendous capacity and is independent of the other lanes. In copper cables, electrons carry the information and do not come in different colours.
Connecting the cities
Communication networks are obviously not only about transporting signals from A to B but also need to bring signals to many different places according to the required destination. So, the signals need to be routed in the nodes of the network. And again, the extra dimension of wavelength makes optical routers much more powerful than electrical ones.
In particular, we have done a lot of investigations into all-optical routers. By using tuneable wavelength conversion techniques, the incoming signals can be internally converted to other wavelengths and passive wavelength-routing devices then bring the signals to the desired output ports. The signals thus stay within the optical domain and are not first converted to electrical signals, switched and then converted back into optical ones; this would happen in electrical routing nodes. It may be compared to driving with your car to a roundabout and choosing the right exit: of course, you prefer to stay in your car and do not want to get out, walk to that exit and get into another car.
The traffic in telecommunication networks has predominantly become internet traffic, so traffic streams are therefore constituted by packets of data. These packets need to each be routed to their specific destination. Within the network nodes, very fast switching is needed to bring subsequent packets to the right addresses. The packet contains a label which indicates what its next address should be. The packet switching is controlled by the routing table, which reads the packet’s label and determines which new label should be attached to the packet in order to get it to the right next node. This so-called label swapping should be done without changing the data contents of the packet.
In our group, we have investigated a range of optical technologies for this label-controlled packet routing while keeping the data in the optical domain in order to avoid limiting the node’s throughput capacity. In the European Commission funded project STOLAS (Switching Technologies for Optically-Labeled Signals), which I was happy to lead, we have adopted a general architecture in which tuneable wavelength converters change the wavelength of each packet .
In the capitals of data
Besides routing packets in the network nodes, optical packet switching has become highly important in internet data centres which have to route massive amounts of packetized information among the huge number of servers inside the centre. The networks inside a data centre are also largely based on fibre, and optical routing between the servers without needing to do optical-to-electrical signal conversion and vice-versa can save a lot of energy and reduce internal delays. Data centres are consuming lots of energy and, with the booming growth of internet traffic, they have ever more work to do. So, saving energy and increasing speed through optical routing and signal processing techniques is highly relevant.
To and in the house
Fibre-to-the-Home (FttH) makes it possible to extend the optical superhighway all the way down to the user’s home so that the last connection to the home is no longer the bottleneck in getting broadband services to the user . Twisted pair copper cables were originally installed for telephony and have served as the final link to the user for decades, but these are inherently narrowband and need advanced signal processing to achieve higher data speeds.
Coaxial copper cables were originally installed for cable TV and have a pretty large bandwidth of about 1 GHz. But again, they have a limited reach and need intermediate amplifiers in street cabinets to reach out to users’ homes. Data transport at higher speeds can be achieved, up to some hundreds of Mbit/s. Both twisted pair copper cable access networks and coaxial copper cable access networks need to be upgraded each time when users require higher capacity and it is apparent that such networks are not future-proof as internet usage is increasing fast. The upper parts of these networks have already largely been replaced by optical fibre.
For twisted copper pair cables, the urgency is the highest, so KPN, Open Dutch Fibre (with T-Mobile) and (more recently) Delta have already spent much effort on installing fibre all the way to the home. They have ambitious plans to connect every home in the Netherlands before the end of this decade. With FttH, connection speeds of up to 1 Gbit/s are typically offered, which is satisfactory for many residential services. For example, downloading the Lord of the Rings trilogy of 61 gigabytes would require 5.4 hours with a 25 Mbit/s DSL line, whereas this can be done in 8.1 minutes with a 1 Gbit/s fibre line.
Light in each home
Although the information highway can be extended to each home with FttH, there is still a last bridge to cross in order to reach users: the indoor network. As of today, there may be a variety of cable networks in each home, each tailored to particular kinds of services: twisted copper pairs for fixed telephone and fax (although mostly obsolete by now…), coaxial copper cables for video and radio equipment, cat-5 or cat-6 cables for connecting Wi-Fi routers, desktop computers, servers, printers, scanners, etc. Communication may even run on the 220 V power supply lines by means of power-line-communication (PLC) units. This jungle of networks complicates the installation, maintenance and upgrading of services as well as the interactions among these networks. Optical fibre is a broadband medium which can carry many services independently of each other, making it an ideal candidate to unite all of these into a single network.
It is fully up to the users which network(s) they want to have inside a house and they are not restricted by public network operators. However, silica single-mode fibre, as used in FttH lines, cannot easily be handled by unskilled users; this is brittle and needs high-precision tools to join two fibres. Two decades ago, initiated by Djan Khoe, we had therefore already started to investigate plastic optical fibre (POF) which features a large light-guiding core as well as high ductility. POF is therefore easy to install in a do-it-yourself fashion. Due to its relatively large losses, its use is restricted to short links of a few tens of meters only, but this is sufficient in many home scenarios. It also has a limited bandwidth due to its large core. We have investigated advanced multitone signal processing techniques and managed to still get Gigabit/s Ethernet speeds over indoor links with these.
Increasingly, the user wants to not be bound by a wire, and indoor wireless communication by means of Wi-Fi and Bluetooth technologies is becoming more abundant. This is also driven by the upcoming Internet of Things wherever more home appliances need to be connected wirelessly. Typically, such wireless connections are made by radio technologies, notably Wi-Fi and Bluetooth. But these technologies have limited reach and need to be fed by a wired network for which fibre is the preferable future-proof unifying medium. A lot of research in our group is therefore being done on in-building optical fibre networks, through which we study how to transport and steer radio signals over fibre.
Just after I joined TU/e, we started to explore how we could combine the best of two worlds: freedom of movement through wireless connectivity enabled by radio techniques such as Wi-Fi and Bluetooth, and transparent broadband connectivity throughout the whole house by means of a fibre backbone network. We started radio-over-fibre research in 2001. In order to transport high-frequency radio signals over bandwidth-limited indoor large-core fibre, I proposed a technique which we called ‘optical frequency multiplying’. This technique, which we patented , can generate an extremely pure radio carrier wave at mm-wave frequencies, which can thus carry high data rate radio signals. This is dispersion-robust, so can readily be applied in dispersive indoor multimode fibre networks.
Moreover, we are at the verge of a new NWO (Dutch Research Council) Perspektief program ‘Optical Wireless Superhighways’ (OWC), which I am happy to lead together with Prof. Eberhard Gil of TU Delft, including for some time beyond my retirement. It will explore the opportunities of OWC at all length scales, ranging from ultra-long links between satellites to short links within indoor rooms. In this program, researchers from TU/e, TU Delft, the University of Twente, the University of Leiden and the Free University of Amsterdam and a range of industrial partners will work closely together.
Optical wireless is right around the corner. It is remarkable that optical communication itself actually started with optical wireless: in ancient history, the Greeks relayed the news of the falling of Troy to Athens by means of fires on mountain tops. Alexander Graham Bell and his assistant Charles Sumner Tainter invented the photophone in Feb. 1880 and Bell considered this as his most important invention. Ships use wireless communication between them via morse code with optical signal lamps. Today’s research on optical wireless communication may be seen as an exciting continuation of this journey, expanding it from its historical embryonic start into a powerful future of pervasive optical communication. Moreover, the Netherlands has been the cradle of Wi-Fi and Bluetooth, and our BROWSE technology  may prove to be another successful wireless technology from the Netherlands.
