New application discovered for LED’s… to help see through flames!

Usually seeing through the flames of a fire is nearly impossible, which poses a big challenge for firefighters and the manufacturers of building materials. It’s interesting to discover that researchers have now uncovered a way to see through the flames produced by a fire with just two readily available pieces of equipment. These are a Camera fitted with an optical filter and a light source which emits a blue light using LED’s (Light emitting diodes). So, Good news for LED Circuit Design enthusiasts.

The task given to the researchers was to understand how a fire destroys a structure, these tests were run in their own laboratory and on test buildings. Previously, measurements were taken before and after the fire, furthermore following the fire a model would be produced by them showing how the fire progressed to achieve the measurement taken after the fire. The problem which the researchers found with this approach is that a high degree of guess work was involved during the duration of the fire where they simply couldn’t see what was going on beyond the flames. It is critical to know how and exactly when certain items are destroyed by a fire.

Another problem faced by the researchers was that most tools and sensors do not work reliably when subject to extreme heat, even at a distance. Also a camera alone with an optical filter to provide an image of the fire was still unclear and mainly drowned out by flames and created an overwhelmingly red theme. So, the image was pretty useless for the objectives of the researchers which was to see inside the fire in real-time.

This is where the blue light source comes into play, Blue lights have previously been used to view hot materials but never in this extreme application. Researchers discovered that whilst illuminating the fire with these powerful LED’s and recording at the same time with the camera they could actually see beyond, through the flames. This has proved to be a ground breaking discovery and now is being used to determine how building materials are affected by the flames.

Here at Arrow Technical we regularly work with LED’s in numerous lighting applications from LED Circuit Design to various electronic volume manufacturing solutions which incorporate the use of lighting LED’s. So, it is eye opening to see the various other applications in which they can potentially be used. We will be keen to follow how this technology could be formed to potentially aid our fire services.   We have already designed other products for advanced firefighting such as head-up displays, breathing monitoring to prevent hyperventilation and advanced inertial guidance systems to lead fire crews through environments when traditional compass and GPS instruments will not work. Please view our Services page to see if we could be of any assistance.

We are so much more than just an electronic design house!

We are so much more than just an electronic design house!

Many people know Arrow Technical as just an Electronic Design company, being a designer of advanced new electronic products, but we are so much more than simply that. As well as designing new products we also manufacture them in-house and all under one roof. And, it doesn’t stop there.  Many times we are required to design products which interface by wire or wirelessly to other systems located either locally or remotely.  We are regularly asked to develop and supply the entire system at both ends so it’s a single point of contact to get the whole job specified and done.

In this respect, we do PC and mobile phone apps.  We also design and supply advanced PLC based control panels (and simple ones) and write advanced industrial control and monitoring software to run on them, e.g.

  • Connection to SCADA – no problem
  • Connection to remote servers and platforms – no problem
  • IoT based products and Cloud services to interface to them – no problem.
  • Battery power – no problem
  • High power, even very high power – no problem

Go to our service page and see the full range of services we provide to our clients.  You might be surprised with the range of services we can offer.

We have had over 20 years developing class leading solutions for industry, science, medicine, military and the home.  We have a huge library of functions and features we can put together to define a new product for a specific market, quickly, reliably and very cost effectively.  If its electronic and you need it, we have probably already done it before, or something very similar.

Give us a call and don’t hesitate to get in contact.  Get in touch if you would like to learn more on our Contact us page.


New Technology emerges from Apple to reduce tech-induced distractions!

New Technology emerges from Apple to reduce tech-induced distractions! 

As Product Development Consultancy its nice to see new technology has been announced from Apple Inc. with a new range of features aiding users to monitor their own Mobile device. This new feature will be featured as a part of the forthcoming IOS 12 Software. It will compromise of a weekly report that shows users in which areas they are most using their devices. This data will then help the user to identify in what ways their mobile device is most distracting them. As Product Development consultants Arrow Technical regularly monitor the inspiring ongoing developments at Apple to ensure the technology we develop is in tune to the leading market trends.

Apple have also enabled the feature to send out reports to any parents’ phone from their children’s and to set time constraints on application usage. With Mobile devices being such a big part of today’s society it has been recognised that usage can affect the mental health of users, particularly children. Here at Arrow we work within the Medical Product design industry amongst others so we know just how much of an impact this simple yet effective innovation could have.

More features include a new updated Do not Disturb feature, a new bedtime mode which will enable user to dim their screen and hide notifications until morning. As well as new group calling capabilities on Face time for up to 32 people.

It’s great to see Apple offering innovative products with the consumer’s mental health at the forecourt. With most of society being geared towards a features arms-race, offering technology which trumps other mobile device manufacturers, the actual long term health effects of extensively using their products for the consumer can often be overlooked. You can’t change what has happened, you can only control how you react in future.

We support these kind of considerations in advanced product developments.  It’s in tune with Arrow Technical’s inherent design philosophy that technology should work in harmony with the human race and make us better people and not be worse off for the experience.

Eggcellent news! Eggs offer surprisingly good electrical performance

electrical research
electrical performance from egg

Egg-based electronics’ offer surprisingly good electrical performance. Egg white also known as egg albumen is not only good-tasting, it also has very good dielectric properties. It boasts a high transparency and high elasticity. This makes it a promising material for fabricating transparent, flexible electronic devices. In a new study, researchers have shown that when egg albumen is mixed with hydrogen peroxide a series of chemical reactions occur that transforms the bio material into an active film. This can then be used to make transparent, flexible resistive memory devices.

This is not the first time that egg albumen has been incorporated into electronic devices. Previously, the albumen from chicken and duck eggs has been used in transistors and other devices as the dielectric (insulating) layer. However, the new work marks the first time that egg albumen has been used to make resistive memories. These memories are being developed as a next-generation alternative to the silicon-based memories that dominate today’s electronics.

Here at Arrow we will be keen to get our hands on them and test against the silicone based products, if they do come to market that is!.
The Research is ongoing at the Southwest University in China. If you want to find out more about this electrical breakthrough follow the link below.

July this year is a year which Arrow celebrates, as it marks the 10th Anniversary of our move to the Advanced Manufacturing Park in Sheffield.  We have seen windmills and companies come and go and buildings go up all around us.

It was a very new idea when we first arrived and took a lot of vision and initiative from the Sheffield and Rotherham support agencies to get it off the ground.  Back then, who knew what a storming success it would have become by now and still growing rapidly.

We are so proud to have played our small part in its journey and are still the only electronics product design and sub-contract electronics Assembly Company on the whole park.

Who knows what the future for the next ten years holds but its looking bright. For more information on the Advanced manufacturing park visit their website here…


Premature births predicted using ‘smart electronic pen’

A new test using a smart electronic pen promises to revolutionise the prevention of premature births by accurately predicting the chances of pre-term delivery up to three months in advance.

The “pencil-looking” device which uses state of the art digital signal processing techniques, will save the NHS £1 billion a year and can alert doctors to tell-tale accumulations of moisture in the cervix, giving them the chance to intervene and artificially prolong pregnancy.

The new test, which has been trialled at an NHS hospital in Sheffield, takes a maximum of 15 seconds and is so simple it could be used by GPs or nursing staff.

Gynaecologists currently rely on time-consuming and expensive procedures such as ultrasounds or foetal fibronectin swabs, which yield many false positives and, even when accurate, can only predict premature birth a few days hence.

By contrast, the new device can detect tiny amounts of moisture on the outside of the body and uses wireless technology to send a signal to a computer which give the medic a “red, amber, green” result indicating how likely a premature birth is.

The test, which could be ready to roll out across the NHS within three years, can accurately predict premature birth from as early as 20 weeks gestation.

Arrow Technical Services Ltd are involved in using advanced electronic techniques to develop this project further for more complex applications as well as several other related medical devices in partnership with the teams at The Sheffield Hallamshire Hospital and Sheffield University.  We are proud to be part of this technology development program.
