Smart chip gives instant food analysis

Published

on

Si-Ware Systems (SWS) has announced its NeoSpectra Micro, a chip-scale, near infra-red (NIR) spectral sensor that analyses materials onsite without the need to send samples to a lab.

Si-Ware Systems (SWS) has introduced the first integrated micro-spectrometer for broad industrial and consumer use. The product, NeoSpectra Micro, is a small, chip-scale, near infra-red (NIR) spectral sensor that quickly analyses materials onsite without the need to send samples to a lab, enabling dramatic time savings and accurate, actionable data in the field or on the plant floor.

The device is small enough and thin enough to be incorporated into a smart phone case or designed into an existing mobile product. Product applications include scanning for food safety, and evaluating soil health, oil and gas composition, and pharmaceutical purity. Delivering the same functionality as conventional “bench-top” spectrometers in labs, the integrated NeoSpectra Micro brings to end-users the ability to immediately quantify composition, detect impurities and ascertain quality, speeding analysis of samples from days to minutes without the need for offsite lab verification.

NeoSpectra Micro builds on the success of the popular and cost-effective NeoSpectra spectral sensing module used by system integrators for development of industry-specific hand-held and inline spectrometer applications. The device is currently in use in agriculture, petrochemical, and healthcare industries.

A Real Spectrometer — at Component Size

NeoSpectra Micro for the first time brings high performance spectroscopy to the size and cost of a sensor component.  At 18x18mm and only 4mm thick in a self-contained package, it can now be easily incorporated into consumer electronic products. Until now, spectroscopy and material analysis have been notoriously absent from consumer applications due to size, form factor and cost concerns.

“Now with NeoSpectra Micro, high performance material analysis can be a reality in the consumer electronics world,” said Scott Smyser, executive vice president at Si-Ware Systems. “In the same way that inertial sensors, accelerometers and gyros became small enough and low-cost enough for consumer electronic products — enabling a host of applications for motion sensing — NeoSpectra Micro will open up new and unprecedented applications for material analysis.”

Large Unmet Need for Material Analysis

According to Paris-based market research firm Tematys, market size for compact spectrometers is estimated at $655 million for 2016 and will grow to almost $1B in 2021. The research firm forecasts that consumer applications will see have some of the largest growth at a 54% Compounded Annual Growth Rate (CAGR) from 2015 to 2021.

NeoSpectra Micro can be an effective solution for original equipment manufacturers (OEMs) targeting the consumer markets, since the integrated device is very similar to components in terms of size and cost. The tiny package includes all the system components: the MEMS interferometer, the photodetector, the light source, and also the electronics chips that perform system control and data processing. This facilitates integration, reduces development risks for system developers, and enables faster testing in different application environments.

Versatility is Key

NeoSpectra Micro not only offers an unprecedented wide spectral range that makes it suitable for many industries, but it is also the only chip-sized solution that operates at higher NIR wave length ranges (higher than 1,150 nm up to 2,500 nm). This extended range enables measurement of more materials with higher accuracy. In addition, it allows measuring samples in different form factors including particles, flat surfaces and even ground samples with no need for sample preparation.

“There is a pressing unmet need for rapid material analysis and actionable data in a broad range of applications, from consumer and wearables to industrial in-line and on-site quality control and scientific applications,” said Bassam Saadany, Optical MEMS business unit manager at SWS. “Developing a tiny spectrometer at a sensor price point, for out-of-the-box use across many sectors, requires a wide spectral range at the higher end of Near InfraRed. This places NeoSpectra above and beyond any other offerings on the market.”

NeoSpectra Micro Enabling Smartphones, Wearables and IoT

Having a low-cost, miniaturized NIR spectral sensor opens the door for a new wave of usage models for NIR spectroscopy. To showcase the potential of NeoSpectra Micro at Photonics West at the end of January, SWS has designed it into an iPhone case and developed a demonstration iPhone app. The demo app will scan and measure food and coffee to accurately detect and quantify such elements as gluten and caffeine levels.  The iPhone case was developed by XPNDBLS, and the spectral analysis algorithms were developed by GreenTropism.

“We are excited to add NeoSpectra Micro to our product portfolio. We believe it will change the way we perceive spectroscopy, taking it out of the lab environment and bringing it into consumer hands.” said Smyser. “Unlike other spectral sensor solutions out there, NeoSpectra is the first chip-scale spectral sensor with the high performance and reliability known for FT-IR spectrometers, the de-facto standard of high precision spectroscopy.”

In addition to smartphone-based spectrometers, NeoSpectra Micro can also be designed in to wearable devices, where NIR spectroscopy can non-invasively measure biochemistries in the body including glucose and ethanol/alcohol.  NeoSpectra Micro’s size and cost now enables NIR spectroscopy for the next wave of sensing for the human body, or even as smart sensors in Internet of Things (IoT) applications.

How NeoSpectra Works

NeoSpectra products are a built around low-cost, miniaturized, Fourier Transform InfraRed (FT-IR) spectral sensors that are based on MEMS technology. The sensors determine the spectral content of the input light, and generates spectrum data corresponding to the measured light. Today, NeoSpectra sensors operate in the NIR spectral range between 1,100nm and 2,500nm, enabling material composition analysis and identification in a wide range of application areas.  NeoSpectra technology allows for operation in the mid infra-red (MIR) and future-generation products will offer sensing in the MIR.

Prepare your cam to capture the Blood Moon

On 27 July 2018, South Africans can witness a total lunar eclipse, as the earth’s shadow completely covers the moon.

Published

on

Also known as a blood or red moon, a total lunar eclipse is the most dramatic of all lunar eclipses and presents an exciting photographic opportunity for any aspiring photographer or would-be astronomers.

“A lunar eclipse is a rare cosmic sight. For centuries these events have inspired wonder, interest and sometimes fear amongst observers. Of course, if you are lucky to be around when one occurs, you would want to capture it all on camera,” says Dana Eitzen, Corporate and Marketing Communications Executive at Canon South Africa.

Canon ambassador and acclaimed landscape photographer David Noton has provided his top tips to keep in mind when photographing this occasion.   In South Africa, the eclipse will be visible from about 19h14 on Friday, 27 July until 01h28 on the Saturday morning. The lunar eclipse will see the light from the sun blocked by the earth as it passes in front of the moon. The moon will turn red because of an effect known as Rayleigh Scattering, where bands of green and violet light become filtered through the atmosphere.

A partial eclipse will begin at 20h24 when the moon will start to turn red. The total eclipse begins at about 21h30 when the moon is completely red. The eclipse reaches its maximum at 22h21 when the moon is closest to the centre of the shadow.

David Noton advises:

  1. Download the right apps to be in-the-know

The sun’s position in the sky at any given time of day varies massively with latitude and season. That is not the case with the moon as its passage through the heavens is governed by its complex elliptical orbit of the earth. That orbit results in monthly, rather than seasonal variations, as the moon moves through its lunar cycle. The result is big differences in the timing of its appearance and its trajectory through the sky. Luckily, we no longer need to rely on weight tables to consult the behaviour of the moon, we can simply download an app on to our phone. The Photographer’s Ephemeris is useful for giving moonrise and moonset times, bearings and phases; while the Photopills app gives comprehensive information on the position of the moon in our sky.  Armed with these two apps, I’m planning to shoot the Blood Moon rising in Dorset, England. I’m aiming to capture the moon within the first fifteen minutes of moonrise so I can catch it low in the sky and juxtapose it against an object on the horizon line for scale – this could be as simple as a tree on a hill.

 

  1. Invest in a lens with optimal zoom  

On the 27th July, one of the key challenges we’ll face is shooting the moon large in the frame so we can see every crater on the asteroid pockmarked surface. It’s a task normally reserved for astronomers with super powerful telescopes, but if you’ve got a long telephoto lens on a full frame DSLR with around 600 mm of focal length, it can be done, depending on the composition. I will be using the Canon EOS 5D Mark IV with an EF 200-400mm f/4L IS USM Ext. 1.4 x lens.

  1. Use a tripod to capture the intimate details

As you frame up your shot, one thing will become immediately apparent; lunar tracking is incredibly challenging as the moon moves through the sky surprisingly quickly. As you’ll be using a long lens for this shoot, it’s important to invest in a sturdy tripod to help capture the best possible image. Although it will be tempting to take the shot by hand, it’s important to remember that your subject is over 384,000km away from you and even with a high shutter speed, the slightest of movements will become exaggerated.

  1. Integrate the moon into your landscape

Whilst images of the moon large in the frame can be beautifully detailed, they are essentially astronomical in their appeal. Personally, I’m far more drawn to using the lunar allure as an element in my landscapes, or using the moonlight as a light source. The latter is difficult, as the amount of light the moon reflects is tiny, whilst the lunar surface is so bright by comparison. Up to now, night photography meant long, long exposures but with cameras such as the Canon EOS-1D X Mark II and the Canon EOS 5D Mark IV now capable of astonishing low light performance, a whole new nocturnal world of opportunities has been opened to photographers.

  1. Master the shutter speed for your subject 

The most evocative and genuine use of the moon in landscape portraits results from situations when the light on the moon balances with the twilight in the surrounding sky. Such images have a subtle appeal, mood and believability.  By definition, any scene incorporating a medium or wide-angle view is going to render the moon as a tiny pin prick of light, but its presence will still be felt. Our eyes naturally gravitate to it, however insignificant it may seem. Of course, the issue of shutter speed is always there; too slow an exposure and all we’ll see is an unsightly lunar streak, even with a wide-angle lens.

 

On a clear night, mastering the shutter speed of your camera is integral to capturing the moon – exposing at 1/250 sec @ f8 ISO 100 (depending on focal length) is what you’ll need to stop the motion from blurring and if you are to get the technique right, with the high quality of cameras such as the Canon EOS 5DS R, you might even be able to see the twelve cameras that were left up there by NASA in the 60’s!

How Africa can embrace AI

Currently, no African country is among the top 10 countries expected to benefit most from AI and automation. But, the continent has the potential to catch up with the rest of world if we act fast, says ZOAIB HOOSEN, Microsoft Managing Director.

To play catch up, we must take advantage of our best and most powerful resource – our human capital. According to a report by the World Economic Forum (WEF), more than 60 percent of the population in sub-Saharan Africa is under the age of 25.

These are the people who are poised to create a future where humans and AI can work together for the good of society. In fact, the most recent WEF Global Shapers survey found that almost 80 percent of youth believe technology like AI is creating jobs rather than destroying them.

Staying ahead of the trends to stay employed

AI developments are expected to impact existing jobs, as AI can replicate certain activities at greater speed and scale. In some areas, AI could learn faster than humans, if not yet as deeply.

According to Gartner, while AI will improve the productivity of many jobs and create millions more new positions, it could impact many others. The simpler and less creative the job, the earlier, a bot for example, could replace it.

It’s important to stay ahead of the trends and find opportunities to expand our knowledge and skills while learning how to work more closely and symbiotically with technology.

Another global study by Accenture, found that the adoption of AI will create several new job categories requiring important and yet surprising skills. These include trainers, who are tasked with teaching AI systems how to perform; explainers, who bridge the gap between technologist and business leader; and sustainers, who ensure that AI systems are operating as designed.

It’s clear that successfully integrating human intelligence with AI, so they co-exist in a two-way learning relationship, will become more critical than ever.

Combining STEM with the arts

Young people have a leg up on those already in the working world because they can easily develop the necessary skills for these new roles. It’s therefore essential that our education system constantly evolves to equip youth with the right skills and way of thinking to be successful in jobs that may not even exist yet.

As the division of tasks between man and machine changes, we must re-evaluate the type of knowledge and skills imparted to future generations.

For example, technical skills will be required to design and implement AI systems, but interpersonal skills, creativity and emotional intelligence will also become crucial in giving humans an advantage over machines.

“At one level, AI will require that even more people specialise in digital skills and data science. But skilling-up for an AI-powered world involves more than science, technology, engineering and math. As computers behave more like humans, the social sciences and humanities will become even more important. Languages, art, history, economics, ethics, philosophy, psychology and human development courses can teach critical, philosophical and ethics-based skills that will be instrumental in the development and management of AI solutions.” This is according to Microsoft president, Brad Smith, and EVP of AI and research, Harry Shum, who recently authored the book “The Future Computed”, which primarily deals with AI and its role in society.

Interestingly, institutions like Stanford University are already implementing this forward-thinking approach. The university offers a programme called CS+X, which integrates its computer science degree with humanities degrees, resulting in a Bachelor of Arts and Science qualification.

Revisiting laws and regulation

For this type of evolution to happen, the onus is on policy makers to revisit current laws and even bring in new regulations. Policy makers need to identify the groups most at risk of losing their jobs and create strategies to reintegrate them into the economy.

Simultaneously, though AI could be hugely beneficial in areas such as curbing poor access to healthcare and improving diagnoses for example, physicians may avoid using this technology for fear of malpractice. To avoid this, we need regulation that closes the gap between the pace of technological change and that of regulatory response. It will also become essential to develop a code of ethics for this new ecosystem.

Preparing for the future

With the recent convergence of a transformative set of technologies, economies are entering a period in which AI has the potential overcome physical limitations and open up new sources of value and growth.

To avoid missing out on this opportunity, policy makers and business leaders must prepare for, and work toward, a future with AI. We must do so not with the idea that AI is simply another productivity enhancer. Rather, we must see AI as the tool that can transform our thinking about how growth is created.

It comes down to a choice of our people and economies being part of the technological disruption, or being left behind.
