Using artificial lights to grow plants has been happening since the 1970s. At first, this was with fluorescent or incandescent lightbulbs, although as time moved on, and research and experimentation took place, it became obvious that LEDs were the way forward. Research conducted by NASA in the 1980s and 90s proved that not only the intensity of light used had an effect on growing crops, but also the wavelength, or colour, of the light involved.
The way LEDs are designed means that their light output is down to a fairly narrow wavelength band, meaning that they would typically give out only one colour of light. This meant that scientists could find out exactly what each type of light did to the plants they were trying to grow.
The results showed that plants grew well when subjected to red light wavelengths, yet did even better when this red light was mixed with a small amount of blue light. As well as being used in photosynthesis, blue light also regulates the opening of stomata, the tiny holes in the leaves of a plant used for water and carbon dioxide intake. This is why red light, being the main driver of photosynthesis, with a little blue added makes for a great combination for growing plants.
This is the reason why horticultural lighting is often purple in colour. It’s a combination of blue and red LEDs working together to promote growth.
American Bright have developed LED horticultural lighting that are not only tuned to precise wavelengths to stimulate growth, but can also be adjusted, to ensure you provide the perfect light for your plants, no matter how new they are.
As we move through the festive season and prepare to approach 2020 we, as always, would like to remember those less fortunate than ourselves. In keeping with our tradition, rather than spend money on cards, for our valued customers and suppliers we have once again purchased charitable gifts from the CAFOD World Gifts collection. This year we have chosen gifts relating to business, food, health and education, which include helping a family start a new bee keeping business, creating vegetable gardens as well as drought resistant crops and to set up a fruit tree nursery – enabling them to both feed themselves and provide income. Each year we try to purchase mosquito nets to protect babies and children – Peter loves nothing more in the world than his 6 year old Granddaughter, Grace, and can’t begin to imagine how the parents, grandparents and families feel when mosquito-borne diseases take effect on their loved ones! Finally this year, having had a breakthrough with Grace’s reading ability, we’ve chosen the gift of teaching someone to read – opening up endless new possibilities for them and their families.
We are, as always, delighted that such gifts have been well supported by our business colleagues for more than a decade since we started celebrating the Christmas and New Year period this way.
Everyone at Steadlands would like to wish our customers and suppliers an enjoyable and peaceful Christmas and we look forward to working with you all towards an exciting and prosperous 2020!

The paperless revolution in which we now find ourselves is not so much a revolution as a slow burning movement anchored primarily by the logistics involved in changing systems and a lingering resistance to wholly trust technology. But the technology is there. Waiting. In fact the E-Ink concept was originally penned way back in the 1970’s and ironically there it stayed, on paper, until a couple of boffins from MIT filed a flurry of patents in the mid to late nineties and early noughties, finally bringing life to the idea.
The technology behind E-Ink is beautifully simple. Floating in a clear oil you have positively charged black particles and negatively charged white particles. This, housed within a small transparent capsule, forms a single pixel, tens of thousands of which are meshed behind a clear screen. Each pixel is placed between electrodes and a charge is given to the electrode to determine the position of the charged black and white particles and thus the image presented on the screen. As per the first law of electrostatics, particles with like charges repel and those with opposing charges attract so when an electrode is given a negative charge, it attracts the positively charged black particles, simultaneously displacing and repelling the white particles. The result is that the white particles are then forced to the top of the screen and that pixel is now a white pixel. Conversely, when the electrode is given a positive charge, it attracts the negatively charged white particles, repels the black particles and we see the pixel as being black. For even greater image sharpness the charge can be bifurcated such that a single pixel (microcapsule) can present as black on one side and white on the other, or vice versa.
In many ways e-ink is simply an advancement of the old etch-a-sketch children’s toy, except where a magnetic stimulus is used to change the state of a pixel, e-ink uses an electrostatic charge. Crucially, there is one further key commonality; once an image is created on the screen, there it stays even with the device powered down. This vital feature is quite unlike almost all other forms of electronic screen where displaying an image requires ongoing power. Whether LCD, LED, AMOLED, QLED, plasma et al, once the power goes, so does the image. With E-Ink, it takes no power to maintain the image on the screen. Until a new charge arrangement is input by the user, the image will remain visible with no degradation.
E-ink isn’t suitable for every application. You wouldn’t, for instance, want your TV to use e-ink. It does, however, excel in some very specific areas. First to mind is of course Amazon’s Kindle device where e-ink brings about incredible battery life, a screen that can be used in bright sunlight and a paper-like reading experience that can be less stressful on the eyes and less stimulating for those who read at night. Digital paper is gathering momentum with some major players like Sony driving the market forward with their 10 and 13 inch tablets. Here, not only can you read text on the screen, but you can also edit text, highlight it, format it, etc, all the while still benefiting from the incredible battery life and the user friendly screen, etc. Sony, amongst others, are also using the technology to try and solve one of the key problems smartwatches have with their incessant demand for charge. With most smartwatches typically yearning to suckle from the national grid daily, watches using E-ink technology can have battery lives of 30 days, 3 months or even a reported 2 years in one case. And the same is happening with smartphones with a recent release boasting a battery life in excess of two weeks. And that’s not to mention the number of small home use medical devices that use an E-Ink screen. Every diabetic, for instance, will be familiar with that monochromatic display.
But surely there’s more to be had from this technology? With it’s incredible flexibility, power efficiency, high visibility and eco friendliness, American Bright agree wholeheartedly and eagerly introduce their E-Paper Display range.
Imagine a supermarket where every item on every shelf is mated to a small E-Paper display showing the product details, the price and the barcode. When the price changes, there’s no more printing labels. When an item goes out of stock, there’s no more stickers to apply or signs to place. It’s just a case of updating that screen through the press of a few keys, locally in the store, centrally from head office or nationally by the group. With full control and immediacy of action, finally the price display mechanism can catch up with the rest of the frenetic paced dynamism of the supermarket industry.
Hospitals have multi-million pound scanning machines, highly trained staff, robotic operations and cellular even genetic manipulation at their fingertips. Yet what is the first thing that happens when you go into a hospital bed? Your name is scribbled on a white board or written on a sticker above your bed. Sometimes. A colleague of mine visited his sister after her gallbladder operation to find that, according to the board, she’d aged 20 years, grown a beard and changed her name to Geoffrey. Imagine if all hospitals simply had American Bright’s E-Paper technology. Every bed clearly signed, every patient added at the touch of a button along with special notes, allergies, dietary requirements, etc. Every time a shift changes, the doctor’s name is automatically updated in line with the roster. How many mistakes could be avoided? How much time could be saved?
And what about café’s constantly changing their menus? Restaurants and their smudges-of-chalk specials boards, vending machines, kiosks and luggage manufacturers? Oh and what about … well, you get the gist. Anything that needs to be regularly updated and displayed is a prime target for American Bright’s E-Paper.
With almost zero power consumption, sizes from a credit card to a wall display and ongoing software support, the future of signage has arrived and it’s called E-Paper from American Bright.

Force Sensing Resistors are used in many different applications worldwide, from helping people walk, to detecting the depth of water. Here we are going to take a look at some of the more unusual, or ingenious, uses they have seen.
Fall Sensing Resistors
FSRs are seeing use in the medical industry, to detect when patients fall out of bed or a chair. FSRs under the mattress or cushion allow a nurse to see how a patient is lying or sitting, how long they have stayed in that position, and can set off alarms when the patient leaves the place in question or doesn’t move for too long. This could be they get up to wander off from the chair they’ve been sat in, or it could be they have managed to fall out of bed. Either way though, the nurses will quickly know, and be able to remedy the situation.
Foot/Fist Sensing Resistors
This application is actually seeing use in two very different, but still related fields. In the robotics industry, FSRs are used for grip and/or feet sensors, to allow a robot to, for example, pick something up, without crushing it. In the same manner, FSRs are used in robot feet for the same purpose. Once a step has been taken, the robot needs to know it’s foot is clearly on the floor so it doesn’t keep trying to step and knock itself over. This also allows a robot to detect if it has stood on something it shouldn’t, and allow it to correct before breaking that something.
The other industry which is seeing very similar use is the prosthetics market, allowing recipients of prosthetic limbs a far finer control over their new limbs than was previously possible.
Front Sensing Resistors
A number of vehicle manufacturers are now using FSR technology in front and rear bumpers, to help with collision detection. If anything sets off the sensors, that will send a signal to start other automatic processes, emergency braking, for example. Vehicles aren’t the only things seeing this use of FSRs though. Collision detection is also useful in automatic doors, warehouse conveyors, and weigh stations, to name but a few examples.
Fertility Sensing Resistors
I had to save the most unusual use of an FSR for last, of course, and I’m fairly sure I don’t want to know how this use was discovered. Apparently, it is possible to determine the best time of insemination using vibrations of a vagina wall. Now, this is not done on people, but has been discovered to offer huge savings in the cattle industry, allowing farmers to know exactly when they should bring their stud bull in to, well, do his thing.
Where once the bull had to be brought in day after day to ensure fertilization, each time costing the farmer stud fees, now, thanks to force sensing resistor technology, the farmer can tell when is the perfect time to bring him in. Great news for the farmer, not so much for the bull!
Davies Molding have recently expanded their offerings of knob toppers to include a new, softer rubber handle. The natural rubber used to make them has a high tensile strength and excellent impact resistance while, at the same time, providing a comfortable, yet sturdy grip. These new handles are available in a variety of sizes and threads to better suit your applications.
In other Davies Molding news, thanks to international business increasing demand, Davies have now started offering their their knobs in metric sizes. These new choices apply to all models of knob on offer, in both thermoset and thermoplastic materials.
Whether you’re in a back office, or going door-to-door, whatever your application, Steadlands has an electronic signature solution that suits you perfectly. From a simple signature pad to sit on a quiet desk to sign letters, we can offer you a selection of esignature devices that reaches up to a completely portable solution capable of converting hand-completed forms into electronic documents.
At the entry level, we offer the ePad, ePad II, and STU-300B. All are suitable for simple signature capture, although the STU-300B also boasts a small LCD screen that allows a signer to see their signature appear under the “pen”. The ePad II also has an identifier code that is unique to each separate pad, allowing an administrator to determine exactly which ePad II was used to capture a specific signature. All three of these units are small and light, and so will easily slip into the side of a laptop case for easy transport, although do still need to be plugged into a computer to work.
The PHU-111KO Clipboard, on the other hand, is a rechargeable, portable solution that lets you complete entire forms (in ink, no less!), and have them automatically transcribed into electronic documents. Those documents are then saved on a local storage device, usually a mobile phone or tablet, and can later be transferred to a company network. Clever use of barcodes also means that the Clipboard can handle multiple documents at once.
For the public, customer facing application, we would recommend you look at Wacom’s DTU-1031X, the DTU-1141B, the DTH-1152, and the DTK-1651. All of these models plug into a PC and are used as you would a second screen. But, thanks to the electromagnetic resonance technology used in the screen and stylus, these tablets are far more useful than simple monitors. The ability to act as a second screen, but with touchscreen capability, means that these tablets are ideal for use in a customer facing environment that requires the customer’s input. Completing entry forms at hotels, or selecting seats at the cinema, are just a couple of examples of where the DT* series will come in useful, and they are, of course, fully capable of handling handwritten signatures on their electronic documents.
In the middle of the range, you will find our most popular esignature solutions. The final two pieces in the ePadLink range are the ePad-Ink, and the ePad Vision, and from Wacom, the STU-430, STU-430V, STU-530, STU-540, and STU-541. All have screens and are suitable for customer facing applications, although they do not have the “full page” capabilities of the DT* series. They can all, however, be used to display simple marketing messages, or even ask questions of the person using the pad. The STU-430 pads, and the ePad-Ink are limited to black and white images, while the Vision, and the higher end STUs are fully capable of displaying colour images with remarkable detail.
All of our esignature solutions come with their own developers’ kits, drivers, and software. For the ePad range, this comes in the form of IntegriSign Desktop, an application which incorporates the SDKs and holds ready-made plug-ins for Microsoft Word and Excel, and Adobe Acrobat. Also available is a standalone piece of software called pDoc Signer which allows for the signing of PDF documents without the need for a full blown version of Acrobat.
The Wacom series of signature pads also has a standalone piece of software for PDF signing, this one named SignPro PDF. The rest of the download for the Wacom pads is all contained in a pair of SDKs, designed to allow you to integrate Wacom’s signature solutions into your own software.
Whatever your application, we can help you find the right solution. For more information, or to arrange a demonstration, please contact us.
As autonomous and self-driving vehicles are perfected and start to see use on the roads, it is natural to wonder, what will the occupants do, now they no longer need to pay attention to the road? This is where IEE‘s latest innovation comes in.
