RFID Tags: Passive, Active And Hybrid

Posted on September 6th, 2010 by Owen Jones

All RFID tags are used to store and ultimately send data. They can best be thought of as the replacement for the bar code. However, they have significant advantages over bar codes. For instance: RFID tags can hold much more data than bar codes; they can be scanned from further away and they can in point of fact send data, not only store data.

There are three varieties of RFID tags: passive, active and hybrid. Passive RFID tags are the least expensive, because they are less complex. They need to be induced to disclose their data by taking power from an RFID reader. When the reader’s radio waves hit them, they reflect back their data. This is the kind of tag used in goods in a retail outlet or on crates in a warehouse.

On the other hand, active RFID tags have a battery, a transmitter and an aerial so that they are always transmitting. These devices are clearly a lot more expensive and so are used only on more costly items like a container, a battle tank, an airplane, on criminals ankle bands or on an animal of an endangered species.

The hybrid RFID tag is capable of transmitting, but it needs to be told to transmit; it has to be turned on by a signal. This signal could be a satellite passing over head. These hybrid RFID tags are also costly, but the battery lasts longer because they are not ‘always on’. These tags have the same applications as the active tags, but are appropriate for use where it is not critical to know where something is every minute of the day: for instance cattle in a field or goats on a mountain.

Passive tags can be attached permanently by sewing them into linings or putting them under skin because they do not have their own power source and do not wear out. This is a cause of anxiety to some people who worry about an invasion of their privacy or the erosion of their human rights.

Active and hybrid tags are most often clearly visible so that the batteries can be replaced as and when necessary. If this is going to unlikely to happen, as in the case of wild animals, the tag can have a biodegradable clasp which will break sometime after the probable life of the battery.

Some uses for RFID tags are on season tickets so that the owner can pass through the style more quickly than a customer paying by cash. It has applications in security; most of the ID badges you see pinned to shirts have RFID built into them so that security guards do not have to stop and query everybody.

They can be put into wagons that repeatedly cross frontiers so that they do not have to stop for identification. They can be put on windscreens so that, as you pass through a motorway toll post, either your credit card is billed or the charge is added to your company’s monthly statement.

Hospitals utilize them on patients so that they do not misplace anyone or misidentify them. RFID tags are useful in our daily lives but people are concerned about criminals being able to read all this information too easily as well.

Methods Of Asset Management

Posted on August 24th, 2010 by Owen Jones

How does one go about taking care of one’s assets – one’s worldly belongings? Well, the majority of people keep their money in a bank, put the jewellery in a strongbox and insure the remainder. But insurance is not really taking care of your possessions, is it? It is taking care of yourself so that you do not have replace them with your own money.

In the old days, and even now, I presume in some places, you would employ a boy to watch over your sheep or cattle or bring them in at night for fear of big cats, wolves or rustlers. These were an early kind of security guard and indeed rich people had and frequently still do have personal body guards.

What if you had a large office with a hundred laptop computers – laptops because employees had to do field work too? How would you keep track on all those? A car is another good case in point and construction site machinery is being stolen all the time even from under the noses of (or with the help of) private security firms.

So what can you do? Get dogs? That works usually, but they can be poisoned. Install video cameras and passive infra-red movement sensors connected to a control centre? That works and a lot of firms and private houses have it, but it is very expensive.

As a low-priced alternative, the police were handing out free pens in the UK, which wrote in invisible ink. The idea was to put your postcode and house number. This ink became visible under a special kind of light. That is all very well if you have a suspect or found property.

Bar codes are not practical, the pen is better. It all comes back to insurance or security.

However, there is another technique that is becoming affordable. The concept has been around for about 85 years, but it was too expensive to use on anything less significant than an airplane or a battle tank.

I am talking about radio frequency identification or RFID for short. The idea is the same one that aircraft have been using since during the Second World War – a transponder emits precoded information in answer to a demand from an RF reader.

Details regarding ownership and particulars of what the item is can be written to an RFID chip also called a tag and the tag can then be glued inside the item that it is to protect.

There are two varieties of tag: the passive and the active. Passive tags will only reply if information is requested by a reader, whereas an active tag is always broadcasting.

Many business people use RFID tagging to keep track of their assets. In the instance of farm animals, most cattle are tagged these days. Most large offices have their IT goods tagged as well and we all know that fashion stores have been tagging clothes for years, although maybe you did not know what that button was that they were taking off at the till.

People are already tagging their dogs, cats and cars and it will not be long before these asset management routines will be used extensively at home too. Insurance companies may insist on it.

How Hybrid Electric Vehicles Work

Posted on August 8th, 2010 by Owen Jones

Filed under Uncategorized | No Comments »

Have you ever wondered about hybrid cars? They definitely look stylish and modern, but what is it about them that makes them so different and so extraordinary? After all, many cars look the same these days, do they not? They are all designed by computer to be aerodynamic and aerodynamic is aerodynamic, so they all end up looking indistinguishable to anyone who is not an aficionado.

Well, the fact is that the difference between a hybrid car and a standard car lies under the bonnet. There are different kinds of hybrid vehicles as well, but the most widespread kind has a hybrid electric engine. Therefore, you could say that what makes hybrid cars special from most other, ordinary cars is their engine.

Or engines actually, because hybrid electric cars essentially have two engines. One, the internal combustion engine, runs on gasoline, LPG or diesel and the other, the electric motor, runs off electricity stored in an array of powerful batteries. On the other hand, normal cars only have an internal combustion engine. It is a good idea to examine these two types of engine separately.

First of all the electric motor. Electrical energy is generated by several components on the car and stored in a large bank or array of powerful batteries. The electricity is created by the turning of the internal combustion engine, just as with a standard car, when it is in use, but also by the wheels or / and the car’s braking system. Different models have different methods of generating this electricity, but they are all very hi-tech and very efficient.

When the car’s internal computers decide that the car no longer needs the strength of the internal combustion engine, it will turn it off and switch to the electric motor instead. The conditions where this might happen are, for example, when you are driving slowly in inner-city traffic, when you are cruising at moderate speed on a flat road or when you are going down hill. This saves a considerable amount of fuel, which is clearly a great saving to you.

However, there are times when you have to have more power than the batteries can supply you, for instance, when accelerating hard, when overtaking or when climbing a hill. At times such as these, the electric motor will shut down and the combustion engine will take over and start supplying power to the accelerator and electricity to the batteries. When the requirement for extra power has ceased, the batteries will take over again.

These decisions are all taken by the hybrid electric vehicle’s (HEV’s) on board computer system and you will not notice much other that a surge of power or a quietening of the propulsion system. This works very well in most scenarios, but some drivers of HEV’s would like to have a manual override for unusual circumstances, such as an undulating landscape.

All in all, cars with hybrid electric engines work very well at reducing fuel bills but they are still too dear to be much more than a gimmicky toy and a salve to the conscience for the rich.

E-Book Reader Price Cuts Could Signal Big Changes In The World Of Digital Publishing

Posted on July 28th, 2010 by Hamish Hayward

Filed under Uncategorized | No Comments »

Amazon, using their Kindle reader family as a vehicle, has been a major player in the development of both the e-book reader and e-book market. The first Kindle was released in November of 2007. In February of 2009, the updated and enhanced Kindle 2.0 hit the market, quickly followed by the large format Kindle DX in the summer of the same year.

The Kindle readers dominated the market with a 60% share of all American e-book reader sales. Sony’s PRS reader – which was actually available in 2006, some time before the Kindle – followed in second place with a 35% market share. Other companies quickly saw the huge potential of the rapidly developing e-book reader market and either launched or updated their own readers in order to get a share of the available sales.

Companies such as Sony, Barnes and Noble, Bookeen, Plastic Logic and iRex did their best to get their share of the new and fast developing e-book market, but the Kindle’s dominance looked to be pretty much unassailable. It wasn’t until the launch of the Apple iPad that the Kindle had any credible competition – even although the two devices were very different and would appeal, you would imagine, to different audiences.

Nevertheless, since the release of the iPad, e-book reader prices have pretty much gone into free fall. The Kindle 2.0, which retailed for $ 359 at its February 2009 launch is now priced at just $ 189. The Kindle DX, which has just had a mini makeover and now sports a new higher contrast screen, has had its price slashed from $ 489 to $ 379. Still a pricey piece of kit, but a lot cheaper than before and also way cheaper than even the entry level iPad (which also has a monthly connection fee associated with it). The price of the Barnes and Noble Nook reader has also dropped to just $ 199.

Whilst the price of e-book readers may be falling, the same cannot be said about the price of the e-books which these devices are used to read. Again, Apple had a hand in this. Apple had, in advance of the launch of the iPad, set up their own book store and negotiated a pricing deal with the major publishing houses which basically allowed them to fix the price of their e-book editions at whatever level they wished. The only rider being that they could not offer the same e-book version at a lower price on any other platform. This effectively put paid to Amazon’s policy of pricing e-books at $ 9.99 or lower and was very popular amongst the publishing companies.

Although Amazon had to modify their approach, it wasn’t all bad news for them – or for Barnes and Noble either. Amazon had always given the impression that they were much more interested in book sales – and e-book sales – than they were in hardware sales. How else to explain the fact that they had bent over backwards to make it possible to read Kindle books on such a wide variety of different devices? It’s possible to read Kindle books on the PC, the Mac, the iPod Touch, the iPhone, the iPad, the Blackberry and any mobile device that runs Android. The latest price movements mean that Amazon, and other companies such as Barnes and Noble – and now Apple – who have a significant stake not just in the sale of hardware but also in the sale of e-books, can adopt a policy of selling the hardware cheap and making their profit in the sale of e-books over the life of the reading device.

It may be that the future pricing of e-book readers and e-books will tend to favor such companies over manufacturers who are involved only in hardware production. Looking at the number of different devices which Kindle books can be read on, you would have to suspect that, whether or not the iPad becomes the reader of choice for many users, Amazon will continue to have a huge say in the future of books and e-books for the foreseeable future.

Conserving power and electricity should be everyone’s concern. We must not disregard the fact that our Mother nature is starting to collapse. We must act and let us start on the simple things we can do.

By caring for our environment, we can actually conserve the energy in simple ways such as lowering electric consumption. By building your own solar power, you will be able to produce cleaner energy. There are no known harmful side effects that may impose threat to uses and the environment.

The use of solar panels at home is advantageous and convenient. Since photovoltaic panels are now commercially available, producing solar power became easier. Solar power has been playing a major role even on the old times in providing the needs of early people. The common solar power installation was able to cover the passive heating needs, hot water supplies, and the occasional active heating system.

Aside from using it at home, solar power can also be used commercially. Even businesses resort to the use of solar power system because it is a practical way. Due to the powerful heat of the sun, people makes use of its energy for different uses.

The alternative form of energy is obviously the answer to the growing domestic needs of every nation. Solar power works good in generating electrical energy needed by homes and businesses. It can be possible by using batteries for storage purposes.

Solar power produces supplementary type of electricity to power up household appliances and electronic devices throughout the day. It also covers the night time through the efficient banks of batteries that hold the “charge” received from the heat of the sun.

Some DIY solar power installation provides mutual benefits to the users and providers. It makes use of “net metering” that actually “sells” the electric power back to the utility company resulting to a lower monthly bill.

The awareness about solar power bring more consumers of this system therefore increases the chances of saving our mother Earth. Some solar power system does not work 24 hours straight but it is not an issue since it can still help in slowly decreasing the electric consumption.

You can seek for professional guidance if you are confused with the different DIY solar power manuals. Some installation still needs supervision to ensure that it will work. Using is a very good investment and guarantees positive result.

Learn how to create diy solar panels on your home? It can save you lots of money. Find out more here about solar energy for homes and create your own panels now.

The Main Characteristics Of A Good Ironing Board

Posted on July 23rd, 2010 by Hamish Hayward

Filed under Uncategorized | No Comments »

An ironing board is, without doubt, a mundane item of household equipment to which the majority of people give very little thought. However, it is an essential item for any household and, if you choose the wrong one, then you might end up with badly pressed garments, take more time than you need to when ironing and even put unnecessary strain on your back.

Most people use steam irons these days – or possibly even steam generator irons, which are becoming popular due to the fact that they can reduce the amount of time spent ironing by 50%. For either of these types of irons, an ironing board with an open mesh surface construction is a good choice. This allows the steam to pass through the garment being pressed, through the cover of the ironing board and through the mesh surface of the board itself. When a lot of items are being ironed in one session, this helps to avoid any build up of condensation which might otherwise cause both the garments and the cover of the board to become soggy.

Ironing will be easier if the cover of the board is smooth. It should be secure and with no tendency to slip or move whilst pressing your garments. A cover which is elasticated around the edges, possibly with a couple of cross ties under the bottom surface of the board, will be unlikely to move around on you when you’re ironing. Choosing a metalised cover will mean that some of the iron’s heat is reflected. This will help to smooth the underside of the garment whilst you are passing the iron over the top surface and may reduce ironing time.

The shape and size of the board will depend upon what you generally iron. A smaller board may be easier to manipulate and store – but it will generally require more repositioning of the item being ironed. A good taper on the pointed end will be useful for getting into corners – the shoulders of shirts and blouses for example – and will also be good for collars.

Scissor action legs are pretty much the norm. It should be possible to adjust the height to a level that suits you and doesn’t cause any back strain. If you like to iron from a seated position then legs which have a curve on them – so that you don’t bang your knees on them – are a good idea. The legs should provide good support. A broad T-piece, or legs that splay to a good width and have a connecting bar, are usually good options.

The support for the iron itself should be sturdy enough to take the weight of the iron. Wire type extension platforms are usually okay for standard steam irons. The extra weight presented by a steam generator iron may mean that a longer board which just features a heat resistant plate on a slightly extended surface is better. Alternatively, the base unit of steam generator irons may be positioned on the floor – as long as the connecting hose between base unit and iron is long enough to permit this.

Cut your ironing time in half with a steam generator iron – you’ll wonder how you managed without one.

Does A Hard Water Supply Impact Upon The Effectiveness Of Your Domestic Appliances?

Posted on July 23rd, 2010 by Hamish Hayward

Filed under Uncategorized | No Comments »

The majority of homes are fed with a domestic water supply which provides “hard water”. Hard water is simply a designation which is applied to water which has a relatively high level of dissolved minerals in it. The two most important minerals are calcium and magnesium. There is absolutely no health risk associated with hard water – but it can have an impact on both the efficiency and lifespan of domestic appliances.

Mineral deposits can build up in water pipes, heating systems and in domestic appliances. Appliances which use hot water – kettles, steam irons, dishwashers and washing machines are especially susceptible to this. This is due to the fact that heating the water liberates many of the minerals which then reform as “scale”. As well as domestic appliances, the central heating system may be affected.

A number of different variables have an influence upon how much scale is generated. One of the strongest influences is the temperature of the water. The higher the water temperature, the greater the amount of mineral deposits that will be freed and the more scale that will form. Lowering the operating temperature of household heating systems, dishwashers and washing machines will tend to reduce the amount of deposited scale and will ensure that these appliances operate more efficiently and have an extended lifespan. Choosing a detergent that includes anti-scaling agents can also help.

With appliances such as kettles, coffee makers and steam irons, it’s not really practical to operate at lower temperatures. However, some kettles include filters – which can help to prevent various minerals getting into the sensitive heater elements. Many modern irons now come complete with removable anti-scale traps which gather the scale deposits for easy cleaning just by flushing it under running water. It’s also possible to get a variety of anti-scale chemicals and cleaners which can be used to clean your appliances periodically.

Although there are no health problems associated with a hard water supply, many people will dislike the resulting taste of hot drinks or boiled and steamed food. On the other hand, some people actually prefer the taste of tea that is made using hard water to that made using soft water – it is, in the truest sense of the word, a matter of taste. If you don’t like the taste of your hot drinks and food, then you can make use of a water filter. A simple, but effective, jug filter will work – or you could install an under sink or whole house filter if you prefer.

It may seem like an inconvenience, but it’s well worth the effort to counter the effects of a hard water supply. In addition to the improved operational efficiency of your domestic appliances, use of the correct detergents and the selection of a lower operating temperature, combined with scale removal from time to time, will save you money by extending the life of your appliances.

Take a quick look at our Tefal steam generator iron buyer’s guide and learn how you can snap up a bargain and cut the amount of time you spend ironing.
