In Data Visualisation I looked at the general concept of using a Visualisation Method to make the meaning of data more apparent and gave 2 examples. In this post I look at how we use this is our own business creating new Electronics Products.

Engineering Data is the information used by Engineers to do their work. In our case the Engineering Work is Electronics Design. Data Visualisation is used at both the Engineering Design phase of a project and also the Test and Verification phase. For this post we will look at how test results can be better understood visually.

3D Gravitic Sensor

The first example is a 3D gravitic sensor used for Solar Tracking. We were required to keep the panels on sun using an almanac and had to maintain this within 0.5° because this was a concentrated solar system. The cradle angle was not simple to measure because the panels are on an angle to suit the lattitude of the installation. But we had to now the cradle angle within 0.25° to be sure we were on sun within 0.5°. This was our share of the error budget, another Engineering Concept.  Here are the results in tabular and graphical form. 

First the table:

 Then the graph:

Gravitic Error Versus Angle

In this case the graph makes it immediately apparent that the unit passes the test. It would have been even easier to see if there were solid red lines at +0.25° and -0.25°. 

Precision Temperature Measurement

The second example is a set of PT1000 RTDs used for precision temperature measurement. For this project the required accuracy was 0.5°C absolute and 0.2°C relative to each probe. A simple test was done where we put the probes into recently boiled water and recorded the temperature using a precision temperature data logger we had developed . We knew that the near step change would cause initial divergence in the results but we wanted to see how quickly they settled. So the options were 3 columns of data points 16,000 readings high, or graph it. Guess which was easier to understand!

Here is the end of the numerical results with the initial 15,992 rows not shown:

And this is the graph of all the RTD temperature readings:

Temperature Graph

 And finally, this is a graph of just the differentials between RTDs:

Temperature Differential Graph

 This last graph makes it much easier to see that the probes settle to within 0.2°C of each other almost immediatley and stay there or below for the rest of the graph.

The 3 sets of results are the same data. But how we look at it changes how easily we can understand it.

There are many other examples possible but this is enough to show the idea in action.

My previous post on Information Overload identified the problem we have with handling all the data that is being created in our modern Information Age world. This post has 2 simple examples of the power of information and how it can be more easily understood using Data Visualisation techniques.

I recently received an email showing the expected growth trends in the Australian economy in 2012. One of the things I found hard to make sense of from the article was exactly which sector was doing better so I decided to pull the information from the post for the sectors that had it, put it into excel and do a graph. This is the essence of Data Visualisation. Here is what I came up with.

Data Visualisation

So from this we can now see, that is the point, that the Resources and Energy sector is expected to grow very strongly whereas Advertising and Marketing is shrinking. I sent a copy of the graph to our business mentor Dr Marc Dussault, The Exponential Growth Strategist, as I thought he would be interested. He reworked it slightly and sent back this:

Better Data Visualisation

So there are 2 changes here. The first is that the data is ordered so the trend is clearer. So organising the data better can improve the understanding you get from the same data using the same Visualisation Method.

The second change is that the formatting of the data is more attractive which makes it more likely the information will be looked at. Marc says that is because he did his graph using a Macintosh computer whereas I used a PC running Windows. That is a long running debate but in this case the visual results are clearly better. So formating the visualisation also helps.

Seeing Connections

Sometimes it is the relationship between pieces of information that is important. This second example is our website. This is done using a HTML Tag Diagram Viewer which is free and you can play with it yourself. My thanks again go to  Dr Marc Dussault, The Exponential Growth Strategist for providing this link. The link redraws our primary domain but you can just put your own in if you want to see what that looks like. It was created by Marcel Salathe so my thanks also go to him for creating and making freely available such a useful tool.

Here is what the graph for http://www.successful.com.au looks like.

www.successful.com.au Website Visualisation

This shows how the tags on the pages relate to each other and how the pages link from the home page in the centre to the rest of the pages on the domain. The blog shows as a cluster only in this view. Here is the legend for understanding the colours.

• Blue: for links (the A tag)
• Red: for tables (TABLE, TR and TD tags)
• Green: for the DIV tag
• Violet: for images (the IMG tag)
• Yellow: for forms (FORM, INPUT, TEXTAREA, SELECT and OPTION tags)
• Orange: for linebreaks and blockquotes (BR, P, and BLOCKQUOTE tags)
• Black: the HTML tag, the root node
• Gray: all other tags

So this information is both graphically represented and also Colour Coded, another Data Visualisation technique.

I then decided to see what just this blog would look like http://www.aharef.info/static/htmlgraph/?url=http://www.successful.com.au/blog 

www.successful.com.au/blog Website Visualisation

 So the blog is a lot more complicated. And that aso makes sense. There are more outgoing links and more interlinking since I also reference other posts.

As an Electronics Design company we use Data Visualisation all the time to help us analyse both research results and test results. So I plan to show a few examples of that in my next post.

According to IBM, 90% of the data created in the history of the world, was created in the past 2 years. The article was looking at Social Media Information but the claim was generic. Talk about Information Overload. How do we keep up with this?

There are sceptics that believe this Data Deluge is overstated but even if they are out by a factor of 10, it seems we are in danger of moving from the Information Age to drowning in data.

I worked with a very fast thinker once. Working with him was like trying to see ahead underwater while travelling in the wake of an outboard motor engine. The trick was to decide what to ignore so you could just address the important things. He used it as a tactic to get his own way during meetings. I was reminded of this while thinking about this topic. It seems the whole human race is about to face the same dilemma. How to sort the important information from the huge volume of total information being produced.

Information Overload

Information Relevance

Not all of information produced is of the same quality, usefulness or relevance. Assessing Information Relevance will become increasingly more important. A post on Facebook letting us all know that someone’s dog just farted is not as valuable to know for most of us compared to the passing of a new law that puts a carbon tax on high carbon emitters.

The CERN Large Hadron Collider (LHC) is expected to produce data equal to 1% of the worlds production rate when it is running. This required a new approach to data storage. For those who aren’t familiar with it, the Large Hadron Collider is a higher energy version of the Australian Synchrotron which has specialised detectors that examine the fine details of how the matter of the universe is constructed. The intent is to look for evidence that the Higgs Boson exists as predicted by the Standard Model of particle physics.

Test Everything

I mention it here because they have to record the experimental data knowing that it may be some time before they can fully interpret it. They have planned for the Information Overload as well as the long term Information Storage.

In fact it is a great example of long term planning with the original proposal in 1985 and the construction beginning in 1994 and being complete in 2008. You see the steps involved in LHC Milestones.

Stephen Wolfram has put together a timeline of the Advance of the Data Civilisation and if you are keen you can also buy the  Historical Timeline of Systematic Data from them.

Information Storage

So how do you store all that data?

If we used DVDs it would produce a stack that goes to the Moon and back. That’s too big to store as DVDs.

The increase in data comes from 3 sources:

• new data sources such as ubiquitous sensors, LHC, business metrics, research…
• increased data creation from existing sources such as social media, blogs, web publishing…
• unprecedented processing power

So far the storage solution is the growth of server farms and while many higher density storage technologies are being investigated, most data is stored on conventional hard disks. Redundacy and data security are of course hot topics.

Hard Disk Storage

Information Processing

The other major issue is how do we make sense of all this data. Traditional data Integration tools are considered to be not ready for Big Data, and this is likely to get worse before it gets better. Information Processing is going to be one of the opportunity areas of the next decade.

According to CNN, Data Scientist will be one of the hot jobs in 2022.

Even in the much smaller world of Successful Endeavours where we develop new products and have to do the Innovation, research, Prototypes and testing associated with them; managing all the data requires both discipline and planning.

One of the areas where there seems great promise, but also great confusion, is the Quatum Computer. I’m not going to try and sort that all out here. You can follow the links to get a better idea of the topic. However there is one aspect that does interest me. In my post on Music Electronics I looked at how I got started in my career. One of the things that I spent a great deal of time working on was getting cleaner, clearer and Low Noise Amplification for microphone pickups. So I read a recent IEEE article on Quatum Noise and amplification with great interest.

Quantum Amplification

The full article on Quatum Quiet Amplification covers a range of topics but I am going to focus on the amplification mechanism as this shows some very innovative ideas in operation, and also the nature of research.  What we have below is a microscopic view of the amplification device with the main area of interest on the right and half way down. You are looking at is the core component of a mechanical resonator that amplifies microwave signals.  That’s right, a mechanical structure to amplify a microwave signal.

Quantum Amplification

A more complete picture showing all the components is shown below. Both images are from the original IEEE article.

Quantum Resonator

Research and Discovery

 Now there is a lot of conjecture about whether this will allow them to get to a low enough noise amplification or not, and there is a good argument that the mechanical resonator will have all of the same primary Quantum Noise issues an electronic amplifier has. But it also has the potential to remove, or at least reduce, the effects of Flicker Noise, which is a problem with existing electronics based amplification systems based on the Josephson Junction. It will take some time to see whether this novel approach really does deliver a long term advantage. However it is also a great example of good research and the relationship between Research and Discovery.

They were looking for a way to cool a mechanical resonator when they noticed that under cetain conditions it amplified microwave signals . So they found something new looking for something else. This is the nature of science. And a great example of following a new path of great promise.

Professor Goran Roos

As well as being the Thinker in Residence for South Australia, Professor Goran Roos is considered one of the 20 most significant thinkers of the 21st Century. This morning he was presenting his views on Australian Manufacturing to a combined breakfast meeting of the South East Business Network and SEMMA.

So what did I learn?

Here is the short list on what manufacturing does for an economy:

• R&D is driven by it
• Innovation is primarily manufacturing related
• Value added exports are usually manufactured
• Creates more indirect jobs per direct job than other sectors
• Many service companies have a manufacturing core
• Is the fastest knowledge growth domain
• Is essential for a highly competitive economy

His primary point is that “A healthy manufacturing sector is a must for any advanced economy with ambitions to maintain both economic and social wellbeing“.

Now he has my attention big time. Because this is something I have inherently believed my entrie working life. Australia needs manufacturing.

Manufacturing creates employment

Next  he looked at the contribution of manufacturing to employment and why we have employment issues in Australia. Yes I know the official unemployment figure is low, but that is because many people looking for work are not included in the official figure. So here is how is pans out for employment:

• For each manufacturing job, there are 2.5 other jobs created around it
• In Australia where there are 1 million jobs in manufacturing, that means there are 3.5 million jobs in total associated with manufacturing
• For each working person, there is a dependent person relying on them for income. These can be relatives, children, spouse etc.
• So in total there are 7 million people in Australia dependent on manufacturing

Now lets look at mining:

• For each mining job, there is another job created around it
• In Australia where there are 200 thousand jobs in mining, that means there are 400 thousand jobs in total associated with mining
• For each working person, there is a dependent person relying on them for income. These can be relatives, children, spouse etc.
• So in total there are 400 thousand people in Australia dependent on mining

So the current government policies and industry practices of reducing manufacturing and increasing mining for direct export are actually economic suicide.

The service industry is even worse for indirect job creation though it does employ more people than mining ever will:

• For each service industry job, there is  0.5 jobs created around it
• The ABS statistics for 2010 show roughly 3 million people working in service industries in total including the 0.5 jobs created
• For each working person, there is a dependent person relying on them for income. These can be relatives, children, spouse etc.
• So in total there are 6 million people in Australia dependent on service industry jobs

What this means is that manufacturing is actually the most critical sector in Australia in terms of job creation and future prosperity.

 So lose manufacturing, and you lose a huge number of jobs.

The USA has shed 5 million manufacturing jobs since 2000, primarily to offshoring manufacturing to lower cost economies. These jobs were replaced by low paying personal service jobs. The net result is record levels of unemployment and a trade deficit in every manufacturing category.

He also spoke of the hidden categories, particularly in industrial products, that lead to high export incomes and have been strength of many European Manufacturers. The following diagram shows the  attributes that make these products possible. Note that 4 are to do with knowledge, and 4 to do with strucutre and relationship. This implies you need both.

Invisible Middle Market

Economic Growth and Competitiveness

Economic growth is a measure of how well you have been doing up to now. It is a meaure of the past performance. It applies to yesterday.

Competitiveness is a measure of how well you will keep doing. It is a measure of likely performance. It applies to tomorrow.

So it is more important for the future to be positioned to be competitive, than it is to have had past economic growth. Ideally you will have both.

Some examples of countries that are highly ranked for competitiveness and also economic growth are:

• China
• Singapore
• Switzerland
• Sweden
• Finland

That was a surprise.  Australia ranks at number 15 for competitiveness and growth according to this analysis. The red line is the frontier of highest competitiveness. Australia is a long way from it.

Future Economic Success

Innovation

Goran Roos also had an interesting take on innovation and this fits in nicely with the view of Edward De Bono on Creating Value. He defines 2 types of innovation that are required to addess Australia’s lack of competitiveness:

• Innovate to create value
• Innovate to retain value

Based on this, offshoring is a really bad idea. It is only done to reduce overheads for cost based activities. For value based activities where we retain the value anhd the income from that value in Australia, we should be onshoring!

Knowledge

Manufacturing is the fastest knowledge growth domain. This is an interesting claim and one that had a case put for it to demonstrate the validity. Here is the case:

• Manufacturing generates 15 times the knowledge that mining does per unit of economic activity
• Manufacturing generates 3 times the knowledge that service industries do per unit of economic activity

Professor Goran Roos also pointed out that knowledge is like a race. If you slow down for a bit, then you can’t catch up if the other runners keep going full steam ahead.

Onshoring

It now makes sense that mining for export is not that great an option. Take something of huge potential value, and give it away at the lowest point you can in the value chain.

Onshoring means we pull value creating back in Australia so we get paid for it. And making stuff, and providing the service industries to support that should be our primary strategy for the future.

The other point Professor Goran Roos made is that Australia is not a scale based economy. We don’t have a large local market by world standards and so we should focus on product categories which do not require scale. Or in my language: lower volume, higher value add products. This is also know as Niche Electronics Manufacture.

Thinker in Residence

His speech on the future of South Australian manufacturing is also worth watching and listening too. Here it is:

I went to the open day for the Australian Synchrotron at the Monash Science Park on Sunday. As a member of SEMIP I already knew about the Australian Synchrotron but had never actually visited it. I am very glad I did.

Australian Synchrotron

On the open day I went to 2 sessions. The first was titled “Synchrotrons for Dummies” which was very well presented and gave a good overview of the Australian Synchrotron but more importantly, gave excellent examples of how it is used and what it can be used for.  Here is a short list from one of their brochures, by no means exhaustive:

• Improving fertility
• Examining forensic evidence
• Helping premature babies breathe without getting lung damage
• Improving energy storage
• Improving industrial processes
• Nano-scale material science
• Improving cement

The Australian Synchrotron uses very high energy electrons to create electromagnetic radiation that can be used to either select specific frequencies for analysing, or for getting access to much higher energy or finer resolution imaging. It runs 24 hours a day when in operation and multiple experiments can be run at the same time on what they refer to as Beamlines. Each Beamline can run in parallel with the others as they are independent. The higher energy allows better penetration and the finer resolution which means you can go down to features comparable to a single molecule. So you can think of it as either:

• A very bright light (1 million time brighter than the sun before you filter it back to what you want)
• A very high resolution microscope
• A very high resolution and finely tuned X-Ray imaging system

The Australian Synchrotron website has an excellent set of explanations including How the Synchrotron Works.

Synchrotron Science

The second session was on Synchrotron Science and included a detailed guided tour through the entire complex starting from the electron gun where the initial 90KeV electrons are generated then into the booster ring where the energy is kicked up by a factor of over 30,000 and finally through to the main storage ring where they are circulating at 3GeV energy and as close to the speed of light as we know how to make them.  In fact, they are going so fast that adding more energy makes them heavier just as Einstein predicted. The energy and the equipment involved are staggering. I was reading the individual steering magnet ratings and they are water cooled 6KW devices. And there are hundreds of them, all colour coded according to their specific function.

Australian Synchrotron Science

The guided tour included both a detailed up close view of the equipment and also a trip over the top to see the complex from above.  The entire device is the size of a football oval.

Australian Synchrotron Science Valves

Beam Time

And the commercial arrangements are very attractive. If you have a great idea for a project and it meets the selection criteria, it costs you nothing. If not, you can rent Beam Time as they call it for $400 per hour and usually get a slot within 8 weeks. Given that this is a $300M device, that is an absolute bargain.

Australian Synchrotron Open Day

Now I am thinking about what my clients might be able to do with this amazing facility.

With the recent passing of Steve Jobs, the world has had a reason to reflect on the significant impact some people have. Someone who made everything Steve Jobs did possible also passed away recently. On the 12 October 2011, Dennis Ritchie, the father of The C Programming Language, died at his home in Berkley Heights, New Jersey.

Beginning in 1970 and with the help of Ken Thompson, Dennis Ritchie began the design and construction of a new programming language. It was based on a language developed by Ken Thompson dubbed B. So the next language was called C. And the reason they wanted to create a new language? They wanted to write the kernel for the powerful multi-user operating system UNIX. that was to replace MULTICS which Bell Labs were ending their involvement with in 1969, the same year man first stepped on the moon. And in doing so, Dennis Ritchie and Ken Thompson created the framework on which all our modern computer and communications infrastructure are based.

Dennis Ritchie

The C Programming Language

The importance of The C Programming Language cannot be underestimated. Not only did it make UNIX possible, but it made UNIX possible on multiple computing platforms. It was also the foundation for higher level languages such as C++ and Java as well as most of the core infrastructure of the Internet is based on programs written in C.

A few additional reasons why C is so important:

• Microsoft used it to create their initial software offerings
• UNIX is the origin for OSX and iOS
• 80% of all embedded software is still written in C
• Our business writes the Embedded Software we create in C

The C programming language, Brian Kernighan & Dennis Ritchie

The C Programming Language, Brian Kernighan & Dennis Ritchie, was the language manual for C and was so well written that it made picking up the language easy and was one of the reasons for the rapid uptake of the language.

So much of our modern world depends on the work of Dennis Ritchie. And I along with many others are grateful. He may not have been the public figure that Steve Jobs was, but he is leaving a larger and more enduring legacy.

Here are some further accolades for Dennis Ritchie:

• Without Dennis Ritchie there would be no Jobs
• Dennis Ritchie: The Shoulders Jobs Stood On
• Dennis Ritchie, The Father Of C And C0-Developer of UNIX
• Father Of C And UNIX, Dennis Ritchie
• Dennis Ritchie, Computer-Programming Pioneer
• Dennis Ritchie, Trailblazer
• What we can learn from Dennis Ritchie
• Dennis Ritchie: the other man inside your iPhone
• Dennis Ritchie: Remembering another Computing Genius
• Dennis Ritchie Biography
• Dennis Ritchie Bell Labs

And finally the 1998 USA National Medal for Science and Technology received by Dennis Ritchie and Ken Thompson for their creation of the UNIX operating system and The C Programming Language.

And Ken Thompson and Dennis Ritchie explain what was behind the development of the UNIX operating system

We stand on the shoulders of giants. And Dennis Ritchie was a giant amongst giants.

Have you ever wondered just how green an iPhone really is?

Well today’s blog post was sent to me by Dr Marc Dussault, The Exponential Growth Strategist. It’s an Infographic taken from DailyInfographic.com. At Successful Endeavours, we’re always interested in recycling and sustainable technologies and solutions. You will have seen some of that is past posts on how to be greener with the Electronics Design including Electronics Design for Green Manufacture? , Green Electronics Strategies – Reduce Power While Awake and Green Electronics Strategies – Sleep Saves Energy .

For this post we will use the infographic to specifically look at how GREEN the iPhone 4 is versus the iPhone 3G from the perspective of the production, use and disposal of the phone.  Some key figures I noted or calculated are:

• Production Emissions are 57% of all emissions in the iPhone 4 product lifecycle
• 58.9% of the weight of the iPhone 4 is in materials that are easily recycled
• Packaging Reductions save 14% in transport fuel

The Packaging Reductions are an excellent example of simple things we can all do to save on emissions. And Apple offer a full recycling service that is aimed at being environmentally friendly which is also a great thing to put in place.

Electronics Manufacturing Energy

The area that stands out for me is the energy that is consumed in production of the iPhone 4. This is not an iPhone 4 specific problem but a general problem for Electronics Manufacture. If we want to talk about Green Electronics, then this has to include not just the product we use and the Electronics Waste and Recycling / WEEE, but we also have to get to the point where the Production Emissions, the energy to produce a product, is way less than the energy to use the product. This is a huge issue for Battery Operated Products, such as the emerging Electric Vehicle market, where the Production Emissions for just the battery can be close to half of all the Production Emissions.

Enjoy the infographic from the dailyinfographic Keeping it Green.

10 years ago, LED Lighting was set to revolutionise the general illumination market. LEDs, also known as Light Emitting Diodes, had already taken over are the role as indicator panel illuminators and user interfaces on industrial, commercial and consumer products.  All the trend lines indicated that they would eclipse the incandescent light globe for cost per watt within a decade.

So what went wrong?

LED Lighting - Purple LED Diffused

More power without more light

As the technology was scaled up, the power levels rose and the expected requirements of more heatsinking were being dealt with and all seemed on track for LEDs to take over the world of lighting. But then a snag was hit. The technology got to a point where the efficiency dropped off as more current flowed through the diode. Companies like CREE, LumiLEDs and OSRAM pursued different and moderately successful strategies to try and overcome these limitations but the pace of progress slowed dramatically.

All of this points to a technical barrier we still don’t fully understand but are chipping away at.

Same light less cost

The other issue is the cost per watt in terms of the manufacturing cost of LEDs. The manufacturing process typically uses Sapphire or Silicon Carbide substrated which makes LEDs more expensive to manufacture than conventional semiconductors.  There are several ways to improve this and they are all being pursued in parallel.

The first is the move toward organic semiconductors as covered in my recent post on Printed Electronics I looked at much lower cost techniques for making semiconductors and organic LEDs are one of the possible end products from these techniques. The CSIRO are world leaders in these technologies and are actively pursuing research into flexible electronics including organic displays and lighting. Here the challenge is creating a robust manufacturing technique that produces high volume, low cost lighting. The efficiency may not be as high but the cost per watt is much lower. Organic Semiconductors and organic LEDs will continue to be part of the solution. You can read about their efforts in CSIRO Flexible Electronics.

CSIRO Flexible Electronics

The second move is toward reducing the costs of conventional LED manufacture by eliminating the more costly steps of the process. A recent breakthrough was announced by Bridgelux and reportied in IEEE Spectrum will permit the manufacture of LEDs on silicon substrates.  In Silicon Is Key to Quest for $5 LED Lightbulb the breakthrough is described and the promise is good. This also does not address the efficiency problem but again reduces the cost per watt.

Bridgelux Silicon Substrate LED

Efficiency is the final frontier

The final chapter is yet to be written because the breakthrough we have all hoped for has not yet arrived. In the meantime the problem is being tackled from many sides and advances are being made on multiple technical fronts. LED lighting is an important part of the strategy to reduce our Carbon Footprint.

In a previous post on Printed Electronics we looked at new product opportunities that were being created using new fabrication techniques for semiconductors. But advances are also being made that benefit both conventional or new product concepts.  In The Plastic Processor we get an insight into how you can make a microprocessor using Organic Transistors on plastic film.

The steps look simple, as is often the case on the other side of Research and Development for a new concept:

• the substrate is a plastic film with similar mechanical properties to cling wrap
• print a layer of gold to make electrical connections
• place an plastic on top of that to make the dielectric
• print a layer of gold to make electrical connections
• the organic semiconductor goes on top

And the circuit is complete.  And at less than 10% of the cost of doing a similar process using Silicon.  And of course there are variations on that theme. And better approaches will be developed rapidly now that a first successful attempt has been made.

Organic Transistor

Of course there is still a lot of work to do on getting the reliability and reproducibility up to the levels we expect from Silicon Semiconductors but this is a significant step forward.

And in the latest news, The Plastic Processor, we get an insight into how you can make a microprocessor using Organic Transistors on plastic film. This is certainly getting more interesting quickly.
