Know About Tire Alignment Of A Car

Sean — Wed, 19 May 2010 05:59:30 +0000

Tire alignment is a little known car maintenance which can improve life span and directionality of a car. This is a most important car repair jobs which is mainly ignored by the new car owner. Friction and heat are the two major factors that cause wear and tear in car. Friction damages mechanical part of the car where as heat damage the physical part of the body. In simple terms, lack of lubrication in car is the major factor for frictional damage.

Tire alignment is necessary because it restores the orientation of car tires and reduces the friction. This reduced friction will avoid any wear and tear of a car. A regular tire alignment checkup is necessary because it helps to maintain long life of a car tire. Precise control in terms of directionality while steering a car is another benefit of tire alignment.

Tire alignment is considered on three parameters which deal with the angles at which the tires are oriented with respect to each other and with respect to suspension. These are Camber, Castor and Toe.

Camber - Angle made by the wheel diameter line with a perpendicular drawn from the ground is called Camber. Error in this mechanism can cause major wear and tear of tires.
Castor – This type of angle can be made by steering pivot while looking the wheel from sideways. These types of misalignments can cause steering control problems and rapid wear and tear of a tire.
Toe – This mechanism shows how much the front and back tires are aligned with each other. For better result tire should be in parallel style.

Excessive wear and tear of a tire and non-central alignment of the steering wheel while driving straight is the major indicator for tire alignment problem. According to a car mechanic car wheel alignment is necessary after about 10,000 miles of running or about one year.

Hence, tire alignment is a major repair issue and a car owner always should take care of it. This small repair will help to avoid major problem and other issues of a car.

How To Clean A Barcode Print Head

Sean — Fri, 02 Apr 2010 13:53:54 +0000

The problem with ribbon and adhesive labels is that residue increases and blocks the print head. The increased residue after some time needs the print head to operate harder to generate the image. The harder the components in the print head have to function, the fast they burn out. A print head that is intended to print nearly ten million labels can burn out just after a million if there is no proper care taken. This generates a huge working expense.

Most printers will consist of a release which allows the print head to open. Once the head is open, the apparent method is to clean it with a rag and alcohol. A little amount of alcohol is put on a rag and the print head and platen roller should be wiped clean. After it is done, all the label material and ribbon should be reloaded.

An other option instead of alcohol and a rag is cleaning kits which consist of pads and swabs pre-loaded along with alcohol. In this method, the pad should be removed and should be inserted into the open print head. After this, the print head should be closed and then pad should be pulled through. This helps in cleaning both the head and the platen roller simultaneously.

Features Of Hybrid Cars

Sean — Mon, 08 Mar 2010 12:06:59 +0000

Hybridization of cars can be mild and full and even depends on different drivetrains (components between the engine and driving wheels, also clutch and axle, and components of the driveline).

Features of Hybrid cars are:
Idle-Off: This feature makes the vehicle to shut down its gasoline engine when vehicle is stopped, which saves fuel. In a well-planned system, the engine will turn on and be able to go in very less time (less than time taken to move foot from the brake to the gas pedal).

Regenerative Braking: In a conventional car, mechanical brakes are used (friction) to stop. It transforms the kinetic energy into hot brakes and thereby wasting the energy. Regenerative braking maintains some of the stopping tasks which are done by friction brakes and uses the electric motor to stop the car.

Power Assist and Engine Downsizing: A vehicle has a big motor and battery pack, so that motor can improve the engine to accelerate the vehicle during driving. The power assist ability decreases the requirements of the gasoline engine, and helps in utilizing a smaller, more effective gasoline engine at the same time providing the same performance as that of a larger engine. Engine downsizing can be obtained by using physically smaller engines consisting of less cylinders or limited displacements, or can be gained by using more effective combustion cycles.

Electric-only-drive: This feature makes the car to drive by utilizing only the electric motor and battery pack. This provides complete benefit of electric side of the dual system. At low speeds and at the time of start, the electric motor and battery energizes the car ,and at high speeds the engine maintains car.

Extended Battery-Electric Range: This feature makes the hybrid car to operate completely as a battery-electric vehicle for nearly 20-60 miles, thus enhancing their environmental functioning, provided they are using good sources of electricity.

Hybrid cars are very expensive because they need bigger motors and battery packs to guarantee good vehicle performance and enough all-electric range.

What Is A Barcode Printer?

Sean — Sat, 20 Feb 2010 12:59:15 +0000

Barcode printers have become very important ever since bar codes came into existence. They are utilized in grocery stores, hospitals, farms, and departmental stores.

Barcode printers develops bar codes in printed form by using a symbology which is a language in bar code technology which favors the printer to understand the information that must be converted into a label. Symbologies are mostly machine readable bars and lines which stores information. There are printers, which can print complex bar code symbologies.

These printers will have features like copying and scanning facilities, color printing, data storage using integral memory, cutters and application software. They may also consist of a digital interface, which is necessary to get connected to integral part of PCs and front office equipment.

Flexographic printers are generally used to print on plastic, cardboard and paper. Pad printers are used to print small bar code images on molded and plastic surfaces. Plotters utilize a pen to create line art on paper and other media. There are special printers, which are used for printing bar codes on fan fold, single sheet or corrugated paper. Some printers are particularly designed to print on glass, metals, wood, fabrics, and electronics and semi conductors. Barcode printers, which can generate industrial field bus protocol complying that signals are also available.

What Is Application Software?

Sean — Sun, 14 Feb 2010 07:15:12 +0000

The two major classes of software are application software and system software. System software consists of low level programs and it includes operating systems, compilers, and utilities for managing computer resources. Application software is also called as end-user programs. This software includes database programs, word processors, and spread sheets etc.

Application software is a program that runs on the computer. The good application software is based on the how well it performs the tasks and how easy it is for the users. The term application refers to the application software and its implementation.

Functions of application software:

Application software provides high level service such as send or receives email, and browse information archives.
The major functions of application software are internet functionality, and client server paradigm.
Communication requires a pair of application programmes. Application software initiates the interaction by interacting with protocol software.
The client and server both are two applications. Client application actively initiates the contact. Where as the server application passively waits for a contact.

Which Operating System Is More Functional – Windows Or UNIX?

Sean — Thu, 10 Sep 2009 12:49:42 +0000

Choosing the efficient Operating System is depends on several factors. Whether it is for personal use or for office use, choosing the OS platform is the vital part of long-term plan, as it can’t be changed often. You need to consider your requirements both short-term and long-term and the features of Windows and UNIX before choosing the OS.

The following are the some of the important features and properties of the two Operating Systems that will help you to understand them better.

1.Multi-User System: Windows OS is designed to be used by one person at a time, whereas multiple persons can share UNIX OS at a time in a network.

2.Security: Windows users are burdened with the need for anti-virus and anti-spyware software. On the other side, for UNIX it is not required, as it is more secure than Windows.

3.Bugs: UNIX has a reputation for fewer bugs (programming mistakes) than Windows.

4.Performance: Under low-stress conditions, both have similar performance. However, under high load, UNIX is superior to Windows.

5.Simplicity: To operate UNIX OS we need a little knowledge of Character User Interface, whereas it is very simple to operate Windows OS.

6.Compatibility: If you designed a website under a UNIX server you can easily host it on the Windows server, but the reverse is not always possible.

7.Website Hosting: If you want to use MySQL as backend then go for UNIX. If you need MSSQL as backend then Windows OS is a better option.

8.Application Software: You will get Application software along with UNIX OS package, whereas with Windows you won’t get it.

9.Run the OS without installing it: UNIX can be run with Live CD even without installing it. Windows cannot run until it is installing into hard disk.

10.File System: UNIX protects data with Journalized file system, while Windows uses both journalized and non-journalized file systems. There is less protection of data with the non-journalized file systems.

11.Fragmentation: UNIX file system doesn’t suffer from file fragmentation but Windows file system will be, which results a single file may scatter all over the hard disk as fragments.

12.Crossing the OS boundary: Some Application softwares written for UNIX will not run under Windows and vice versa.

13.Placing User Data: UNIX stores all user data in the home directory making it much easier to migrate from an old computer to new one. On the other hand, Windows stores data anywhere in the hard disk making it hard to backup files when switching to a new computer.

14.Hardware Compatibility: UNIX can run on different hardware platforms but Windows can’t.

15.Supported hardware devices: UNIX supports less hardware devices than Windows.

16.Ability to run without GUI: UNIX can run without Graphical User Interface so it needs less hardware horsepower than Windows.

17.Price: You can get a copy of genuine UNIX free of cost, whereas you have to buy Windows OS.

The two Operating Systems serve different purposes. The above information helps you to choose the better one that suits your requirements.

GPS Cars

Sean — Tue, 01 Sep 2009 09:49:45 +0000

Cars with GPS facility are the latest trend when it comes to the security is concerned. If you have a job that requires as much traveling as mine does, or if you want to ensure your personal well-being wherever you go, you should look at your options for installing a GPS tracking system in your car.

Nowadays, the tracking system is being included in cars directly from the manufacturer. If your car was made before the wave of GPS standards, there are many outlets on the internet through which you can locate a online provider of GPS system that will fit your needs.
One of the best things about GPS technology is its ability to always find out on what road you are if you get lost. You can get a GPS, which will tell you your exact speed, where you are and your average time to destination at the present rate and accumulated time, speed and distance, WOW.

Another important feature about the GPS is the anti theft system. You can trace your car wherever on earth, in case it was stolen.

I found great use of the GPS when I was stranded in a traffic jam and don’t know how to reach my destination. In such cases this is really a godly gadget.

What a Solar storm means to us?

Sean — Tue, 14 Apr 2009 12:37:15 +0000

People on stormy areas really have much volatile life. Storms can occur at any time, and they might have to leave their places and take refuge in some unknown place till storm calms down. When they reach their house, they see that it doesn’t exist any more. Everything destroyed and slashed down; they can’t even recognize the place where they used to live. If just storms on earth can have so much impact on us, what about the storms on our mighty Sun?

These are called solar storms and don’t impact us directly as storms on earth do. The main causes of solar storms are explosions on the surface of the Sun. They impact us more when they occur in the direction of the earth.

The major impacts of a solar storm include disruption in the radio signals, surges in oil pipelines, blackouts.

It is very dangerous for our satellites orbiting around the earth. Our earth, after receiving heat from solar storms, expands its atmosphere causing satellites to re-enter the expanded atmosphere and burn up.

Google Gives Access to Offline Emails

Sean — Thu, 29 Jan 2009 12:15:41 +0000

After innovating many services in the web, Google is set to bring its innovation, which doesn’t include web.

Google has announced its new offline Gmail service. Using this service, people can access to their gmail account even on offline. This new feature is yet to add up to the gmail accounts and once it is done, people can get access to this offline gmail service.

Gmail labs developed a set of programming tools named Gears. This tool facilitates web developers to create off line versions of web-based applications. This very tool is to be used in the new Gmail offline version.

When gmail user accesses to his account his hard drive is synchronized with Gmail servers. Thus, the Gmail’s usual tools become functional offline. When the connection is lost, Gmail automatically switches to offline mode. Here you can perform all the other functions except sending or receiving mails.

For example, you can compose a mail but it isn’t delivered. Instead, it is stored in your outbox. Once the connection is reestablished, your composed mail will be delivered.
