The replacement of projector bulbs is an all-too-frequent occurrence for anybody that has owned a home theater projector for any length of time. While a two thousand hour lifespan may sound like a lifetime to some people, rest assured it is not long before the projector lamp will need replacing. There are however, some general tips that can help to expand the life of a headlamp for the projection unit.Do not touch the lamp with bare handsOne of the most frequent problems encountered is people replacing the bulbs with their bare hands. While this is fine for an ordinary light bulb, it is not a good practice for a projector lamp. The lamp in a projection unit burns much hotter than any regular light bulbs. The effects of touching it with bare skin are equally magnified and problematic.Touching a projector bulb with the bare skin leaves traces of oil on the lamp surface. While this may seem a very minor detail, it is detrimental both to the bulb and the quality of the resulting multimedia display. The oils will get burnt onto the lamp and drastically reduce the lifespan. As the oil is baked into the surface, it actually diffuses the light being projected, reducing the lumens actually being sent to the refractive surfaces. The light will not be enough to project the image that has come to be expected from the home theater projection system. While the problem may not be noticeable at first, over the course of a little time, the quality will degrade to the point of not being viewable.Turn off the projector power after turning off the lampIt is highly recommended to turn the power on the projector to the off position only after having turned off the lamp and allowing it to cool. This will allow the cooling fans to do the job they were designed to do. While rapid cooling and heating result in repeated contractions and expansions of the bulb filament, it is much better that it be done more quickly with the cooling fans. Likewise, turning the projector on and allowing the cooling fans to run for a moment before turning on the lamp will help as well. This will add hours to bulb life expectancy and allow for longer hours of viewing pleasure on the home theater projection system.Constant MovementsConstantly bumping or moving the projector, especially while it is hot can be very detrimental to the projector lamp. The filament in the bulb loses almost all tensile strength when it is heated during normal usage. It is much the same as the filament in a camp lantern. The principle is the same; the filament effectively becomes almost the same consistency as ash, making it extremely vulnerable to damage when it is hot. Even after proper cooling, the lamp filament is very sensitive. Care should be taken when moving the projector for whatever reason. While it is always a good idea to be careful with electronic equipment, some aspects of the home projector are actually a bit more sensitive.It will usually be necessary to move the projector when cleaning the filters. As always, it is a good idea to move it carefully without jerking it around or bumping it any more than needed. Taking an extra moment or two to check the projector mount and make sure it is still securely fastened can also be beneficial and prevent slips and movement which may otherwise be harmful.With a little care and a little preventative maintenance, the projector lamps will still need to be changed, but not nearly as often.
Someone once said "It takes money to make money," and that is mostly true. Today, we might add, "It takes energy to make money," with reference to all the wondrous digital electronics we use every day to conduct business and create things. Problem is that it can take quite a lot of energy to run all the computers, peripherals, big screen display and multimedia installations in our homes and offices. And a bunch more to keep all those cell phones, digital cameras, GPS systems, iPods and handheld gaming systems charged and ready to go. So while the cost of energy keeps rising, and more and more people realize that climate changes, pollution and diminishing oil reserves demand a move towards renewable energy sources, we consume more and more with all of our beloved electronics.Does that mean that the very progress that brought us the wonderful world of digital electronics is also digging us into a deeper and deeper hole of energy dependence and spiraling monetary and environmental costs? It doesn't have to be that way. Business and the environment do not have to be at odds. There is, in fact, a green electronics movement that seeks to make our beloved electronics more energy efficient and environmentally friendlier. The movement covers the entire spectrum from huge international conglomerates pledging to recycle, reuse and conserve, all the way to electronics being more energy-efficient and either bio-degradable or easier to recycle, thus reducing what is now called "e-waste" from millions of tons of landfill to reused and recycled resources. Saving energy and recycling makes perfect sense, and it's no surprise that there are now companies devoting themselves to "green electronics" and energy sustainability. After all, it's good PR and makes economic sense. But it goes farther than that. There are now even companies that sell both digital electronics AND "renewable energy" products. It's easy to see how a firm belief in renewable energy, conservation and sound energy policies may drive an environmentally conscious business owner to sell items like solar and wind energy products as well as digital electronics made by companies that have realized that business and society are interdependent and thus embraced green technology. What is "green technology?" It can be products certified for low emissions, products certified to be more energy-efficient (like the Energy Star pledge and standard), or products using solar chargers or other energy saving technologies. It can also mean support of companies that are actively "going green" by increasing recyclable content, removing environmentally harmful substances, using renewable energy in the production cycle, and supporting environmental conservation causes and projects. Why would companies go green? Because it's not only the right thing to do, but also because it's an increasing competitive advantage to be seen as a green company that cares about the environment. Just like a lot of consumers reject pesticides and insist on organically grown food products, more and more consumers insist on buying green, energy-efficient technology from companies that care. It's good to know that megahits like iPhones and Wii gaming consoles are made by such companies. What we're seeing here is really an inevitable, accelerating trend towards smarter, greener and more efficient and conscientious consumption. We all must fight waste and embrace clean, sustainable, renewable energy.
If you are a cell phone customer, then you should also have a battery charger. The majority of "cell phone" s are accompanied by an AC adapter, which plugs directly into your cell phone and also into a standard electrical outlet for recharging. Depending on the type of phone, it may take up to 24 hours for the battery to fully recharge. But, what happens when you are on the road and your cell phones battery runs out? What will you do if there is no nearby electrical outlet to help recharge your phone? In this situation, the best accessory that you could own is a cable that allows you to connect your cell phone into the vehicles cigarette lighter slot for instant use and recharging. With this method, you can use your cell phone immediately or allow it to recharge if you see that the battery is low.When it comes to battery recharging, it is best to keep all connectors with you wherever you go. If you own a device that allows your cell phone to connect to your vehicle, carry it in a purse or place it in the glove box for easy access. There is nothing worse than having car trouble in the middle of nowhere and being stranded without any contact to civilization. By making sure that your cell phone battery is fully charged and/or by having a recharging cord for your automobile, you will always have the peace of mind in knowing that help is just a phone call away.If you are planning a vacation or business trip via commuter train, you will find that you can recharge your cell phone in one of the plug-ins next to your seat. Because the majority of passenger trains feature an electrical outlet next to the seats, recharging your [*_*]s battery will be a breeze. When traveling this way, also be sure to pack the recharging device for an automobile, which you can use in a rental car when you arrive at your destination.The approach for recharging camcorders is much the same. The only exception is that these units cannot be charged in an automobile, but instead must be recharged at home using an electrical outlet and an AC adapter. The convenience in charging your camcorder batteries is being able to comfortably use the device without worrying about it running down in the middle of a graduation, wedding ceremony or other special event that you happen to be recording. Prior to setting out to record a special event, make sure that your camcorder battery is fully charged and working properly.
Mobile phones have become indispensable and now play a big part in everyone's lives. With the current technology that has made people and nations closer, mobile and handheld devices can truly be considered great inventions and innovations. Gone are the days when one has to go home first before he can use the telephone or go to a public phone booth to place an all-important call to a loved one or business contact. With the presence of mobile phones, everyone has now gone wireless. Communication has, indeed, turned very easy for all.Mobile phone, as it name suggests, provides mobility. It is portable communication device. One can bring it anywhere. It is made possible by satellites that transmit signals for the phone to send and receive. It is very convenient as one can use it anywhere irregardless of time and region.People everywhere have seen the evolution of communication technology. From a phone that uses wires to one that no longer requires any. From the analog to the wireless. In some places, wireless phones were provided with signals by the network company. In other places, a simulated card in inserted in the phone to grab and receive signals and send as well. These phones use the concept of signal transmission and radio wave theories that enables a two-way communication with real time and clearer conversation. From the analog "mobile phones" that only allowed calling and voice conversation evolved the mobile phones that have text messaging features. It is another emergence in the world of mobile technology. A person may send a text message that will be received by another party. This message is sent through a signal passing to a gateway which transmits it to the receiving party. In the turn of the 20th century, mobile phones have become more of a trend and companies have started to make them appear more sophisticated. Mobile phones started with big sizes which transformed to smaller ones and then became bigger again. It has developed much like how computers have. Nowadays, mobile phones are not just for communication. Originally, it had the voice call function but since the technology is growing day by day, the mobile technology grows along with it. Mobile phones now have been created with different functions and usage which are beyond plain communication usage. These functions are constantly updated and additional features are created each day. Mobile phones also serve as mp3 players and/or audio, video file storage units where users may save audio files and listen to the music. Mobile phones now are also equipped with cameras that come in different pixels allowing people to take pictures anywhere and anytime. Almost all mobile phones of these times are designed with games, calculator, organizer, alarm clock, dictionary and many more. These are just now considered the basics. Some updated mobile phones may now take video clips and still photographs of which may be transferred to the computer for different purposes. Many mobile phones are also designed with touch screen features where a person doesnt need to touch the keypad anymore. The screen of the phone is designed to recognize commands as the finger tip touches the screen.Moreover, mobile phones are now used as computers. With the General Packet Radio Service (GPRS), surfing the internet is now made possible. GPRS is used to transmit IP packets which enable users to use the internet wherever they go. People also use their [*_*] in banking transactions where they can send and receive money through phone. Several high technology features are continuously being researched and applied to [*_*]. Not long ago when 3G system was developed. It enables users of the same networks call each other with real time camera. Through this system, one can actually see the person he is calling while talking to him. Long before people finally get familiar with the just launched 3G system, many companies are now researching on the higher system which is the fourth generation or 4G system. Researchers project the new system as faster with a connection speed reaching 100 Mb per second. This is seen to provide a better quality of call. Mobile phones are not only for personal use like it was in the past. With [*_*], reporters and journalists may now take and film news reports. Security system and surveillance are also possible. It is seen in the near future that [*_*] are most likely to replace laptops. With the new [*_*] coming out of the market, viewing and working on documents only found in computers are now possible. It is also seen to replace entertainment devices with all the entertainment features new [*_*] have. Mobile phones do not only play a big part in technology. Mobile phones also show fashion and style. Thus, to make these phones more appealing and attractive, manufacturers produce these phones in different colors, size, shape, and style. Mobile phones are indeed one of the greatest contributions of technology. It has gone far beyond what man can imagine. Now, with the emergence of mobile technology, everyone just cant live without one.
For those who have not yet settled on which high definition disc to invest in, this article will help bring several issues to light. First of all, the potential video and audio quality remain alike between both formats, HD-DVD and Blu-Ray. The difference lies in the laser that reads the disc; where the former uses the identical red laser used to read DVDs, the latter employs a blue laser that reads only Blu-Ray. Both lasers can decode an identical amount of information, called the bitrate. A bitrate can be labeled as the amount of "bits" decoded per second. Generally, the higher the bitrate the higher the quality of video/audio. So a bitrate of, say, 30mbs (megabytes per second) should be preferable to a meager 10mbs. The average hi-def picture, with its superior clarity and contrast, can maintain a bitrate between 15mbs-35mbs; compare this with an ordinary DVD, which averages 2mbs-7mbs.With its ability to store and transmit at a higher bitrate, hi-def media easily trumps the quality of DVD. This higher bitrate allows for less compression, and thus can retain most of the clarity from the original master print of a movie; whereas a DVD will look blown-up and fuzzy. But the differences between HD-DVD and Blu-Ray begin with how they can be played. HD-DVD players have the advantage of backward compatibility, as it can playback DVDs. Blu-Ray players cannot, due to their unique laser, which completely isolates it from older generation technology. But the advantages of Blu-Ray lay in its inherent differences.Blu-Ray players come equipped with Java software, which some believe to allow more interactivity with the user. This gives it the ability to have fancier menus and in-depth bonus options, such as picture-in-picture display. At the moment, bugs and slow performance have hindered some confidence in its support of Java, where Bill Gates complained that it was not user friendly enough to be used in PCs. Counter this with HD-DVD, which uses Microsoft's own HDi Interactive Format. It allows anyone to author simple content, where Java requires a more intimate knowledge of scripting.If all the information so far sounds redundant, it is. The only thing that can make or break a hi-def entertainment center does not stem from the format at all. In fact, it all depends on what you choose to display it on. Be weary of interlaced televisions. Rather than playing back video at 1080p (progressive), the user gets short-changed with 1080i (interlaced). Progressive scan means that the picture gets scanned upon each frame; this results in a properly displayed picture, like a solid photograph, with no aberrations. Interlacing occurs when no progressive scan exists in the television, and so the picture gets displayed as a series of individual lines rather than as a single, uniform "photograph." In short, the fine edges in a progressively scanned movie may otherwise appear to be jagged, or even fuzzy, on an interlaced display.The only reason to get invested in the so-called format war would be to avoid a costly personal investment if "your" format ever loses. Blu-Ray may be considered to be the superior technology, as its unique blue laser, while radically different and incapable of DVD playback, allows for exciting future developments. HD-DVD, largely compatible and user-friendly, is considered by some to be a static technology. Lately, however, Toshiba released its plan to market the format as cheaper, practical alternative to Blu-Ray. And, in the event that you still cannot make up your mind, there exists a combo Blu-Ray/HD-DVD/DVD computer drive that sells for less than $300.
