Types of Barcode Readers

Scanning methods are differentiated by the amount of operator manipulation needed:

  • Pen or wand type readers: needs the operator to filch the pen over codeBarcode scanners
  • Semi-automatic handheld readers: the operator doesn’t need to filch but it need to position the reader close to the label.
  • Fix-mount readers for the purpose of automatic reading: this reading is done by passing the label over the reader.
  • Reader gates for doing automatic scanning: placement of code should be under the gate for short time, letting the scanner sweep to get the code target effectively.

Here is some of the type of readers:

  • Pen type readers

This type of readers has a light source and a photodiode which are placed next to each other on the tip of a wand or a pen. For reading the barcode, the tip of pen swings across the bar in a stable proposition. Photodiode measures the intensity of light which is reflected back from the source of light and get to generate a waveform which is used to measure the width of bars and space in the bar code. Dark bars which is placed in the bar code is used to absorb light and the white spaces is used to reflect light so that the voltage which is created by the generation of waveform by the photodiode is an representation and pattern of space in the bar code.

  • Laser Scanners

The working of laser scanners is same as the working of pen type readers except the fact that they use a laser beam as the source of light and engage a reciprocating mirror or a rotating prism for scanning the laser beam back and forth across the bar code. In case of pen type readers, photodiode is used for measuring the light intensity. While in laser scanners, laser beam is used.

  • CCD readers

CCD readers take into account use of plenty of tiny light sensors which are lined up in a row in front of the reader. Every sensor measures the light intensity instantly in front of it. Every individual light sensor in the CCD reader is very minute and as there are plenty of sensors lined up in a row, a pattern of voltage which is similar to the pattern in bar code is created. The main difference between CCD reader and the pen readers and laser scanner is that CCD measures the emitted light from the bar code and pen and laser measures the reflected light frequency.

  • Camera based readers

The newest and the most unique type of bar code reader which is available are camera based readers. It takes into use a small video camera to take an image of a bar code.  The reader then makes the use of high qualitative digital image processing techniques for decoding the bar code. This video camera uses the same technique as in the CCD bar code reader but instead of having single sensor row here it has plenty of rows of sensors for the generation of image.


Common Misconceptions about Phone Battery

Battery misconceptionAlmost each and every person will be complaining about quick battery loss. And almost each and every person will be having different reasons to specify their battery loss. Some of them would be true but some of them would just be myths. And these myths will spread and it will become the ultimate conclusion for the battery loss. Here are some such misconceptions about quick battery loss of the phone.


  • Batteries have memory

It’s a very big misconception that batteries have memory. It’s a wrong notion that you need to train your battery to conform that it would take the moist charge.  For this, people generally drain the battery of the phone and then charge it. And also people would never plug the phone to charge when it is over 50%. The belief behind it is that the phone battery will develop a habit and it will keep the memory and it will allow just a percent of the charge.

  • Off brand chargers will damage your battery

Again a wrong believed myth that other brand charger will damage the phone battery. It may be possible that it take more time to charge then your’s one but it will not damage your battery unless and until it is not defective. Thus it is perfectly safe to use the other cheap chargers when your original charger which came along with phone is not working. But make sure that when you replace your charger purchase those which are specifically made for that device, if it is not so you might not enjoy the delight of 15 min charge yielding hours of battery run.

  • Overnight charging will damage your battery

The name smart phones are not just given usually, it has feature of smartness in it. So they are smart enough to stop charging when the battery is at its capacity. For better and long lasting battery life, what you can do is to keep your phone charged between the 40 and 80% most of the time instead of full or overnight charging.

  • Don’t use phone while charging

Generally the thought of people is that using the phone while charge will reduce the quality of the charging your phone gets. This is not totally true unless you are using the charger of low quality. Your battery will charge normally only whether you use it or not. So go on using your phone even if it is in charge without any fear.

  • Switching off your phone can damage your battery

False, there is not a bit of truth lying in this fact. Yes, if you leave your phone shut for an extended period of time battery will be drained, but it is ok if you shut the device once in a while. If possible you can also shut the phone and remove the battery is possible. It will not at all harm your battery. In fact in some of the phones a simple reboot can make battery run functionally.

You can remove or add the server from the cloud without any application and devoid of the clear architecture. Contextually, cloud hosting does not involve any physical object which can be labelled as the cloud. Of course, it is a structure of the electronic variant where the storage of data is set up in the different computers. One big processor of storage is what the farms of the server behave like. Many hard drives which are connected together in a sync and building up of the space of cloud with booting methodology takes place.

The working of the cloud hosting is based on the internet but cloud hosting is a piece of the entire system involved in the internet. The urge is to simplify the process in a given framework. The working is essential and ideal for those who are in dire need of communication. Freely connecting with the ideas, stories and data also the sharing process takes place by communication. In no time the entire world can connect through the flow of data to the global hierarchy of internet.

There are many apps which are available in the form of digital media storage. Company of the book seller also collaborated with the server of the cloud based. Large investment has been placed with the cloud server. Options of the quick sharing of data be it the dropbox, app of the cloud and other apps simplifies the process with easy sharing of the files to the friends. It is through the servers of the cloud that you get a private IP and then scaling begins with resizing option from the control panel, in fact snap shot of the server of the cloud will lead to a new version of it.

The cloud servers are tied to the CPU with specification along with the storage and memory. You cannot mount the level of storage which is blocked. For offloading server of the cloud is used. The hosting of the server of cloud is a notable improvement to the farms of the server but the knowhow about is still in its archaic form. The web storage of the mystical ‘cloud’ is filled with connectivity. It is an innovation for the next generation. The system of cloud service is growing in size.

The processor:

The wow factor of this phone is its processor which is a Quad Core Snap Dragon 805 that runs at a blazing 2.5GHz speed. Unlike the S4 model, the S5 will not come out with octo-core, at least not in the recent future. Add a RAM of 2GB to it, and you are pretty much sorted. With this speed, throw any app at it and it will run as smoothly as ever.

The Operating System:

The power packed device comes with the most recent version of android, 4.4 KitKat and newer version of TouchWiz interface.

Battery Backup:

The Samsung Galaxy S5 comes with a battery of 2800mAH which should be enough to give you backup of a day at least. Samsung assured a continuous twenty one hour of backup.


The phone will be available in two versions 16GB version and a 32GB one. The storage is expandable up to 64GB via a micro SD card. For quick transfer of data the phone comes with a 3.0 microUSB port.

Look Wise:

As far as the look is concerned the S5 matches Samsung standards of super chic, slim, light weight phones. It is expected to feature a metal body unlike its usual polycarbonate body. The back is going to be matt soft touch and dimpled all over, which looks better than the faux leather finish other higher range phone features. The phone also features IP67 waterproofing, unlike its last version. This feature prevents it from any water and dust damage. You can submerge the device for as long as half an hour without any damage to it. It will be available in different colors namely Charcoal Black, Electric Blue and Copper Gold and Shimmery White.

The screen:

The device features a 2560×440 quad HD touch screen. The S5’s AMOLED screen is larger than previous version at 5.1 inches.

The blazing .03 seconds autofocus speed of the device is worth on mention.

Best printer for your office

office printerThere are many printers available now days in the market. To choose the best among them is indeed a difficult job. The best printer that is suggested for official purposes is the laser printer. It is a multi purpose gadget which is best suited for all your needs. With the passage of time the price of the printers falls and the choices that are available increase. It must be noted here that the printers with the lowest price is not always the best one to choose. On the contrary the one which is the most expensive is of no use either.

One of the first steps that you must take before purchasing a laser printer is to set a budget. You must conduct a full fledged research and find out the average range of the printers and the features that accompanies each one of it. You must take into account the toner cartridges as they are important for determining cost printing. Color laser printers are costlier and so are the color toner cartridges.

The price of the printers may vary a lot when colored and monochrome models are taken into consideration. If you run a graphic designing or a printing company then, you may require a color laser printer. In order to produce high quality print outs the cartridges will be required in large quantities that may drain it quickly and you will have to incur more costs.

If you require laser printers for text document printing, then you must opt for a standard monochrome printer. This will require less toner and will save on some money. For the purpose of printing color documents a cheaper inject printer can be bought which need not be of a very high quality. Inject cartridges can be bought at cheaper rates and this will conveniently do your job for occasional color prints instead of buying color laser printers.

You must have an idea about the number of pages and the number of times you will be requiring the printer in a month. Slow printing can cost you less but at the same time can take around 10 seconds for the printing of one page. But if you are working in a busy office then a laser printer can do the job quickly at a slightly higher cost.
