The Features and Benefits of the Multisystem LCD TV

What is an LCD Display?

LCD is short for liquid crystal display, and while LCD technology has been around for quite some time, it has been only in the last decade or so that the technology became suitable for the high quality flat panel television and computer monitor displays we see today. The most notable feature of displays using LCD technology, of course, is the thinness of the unit, but the power behind that thin design is actually quite extensive.

The display on an LCD panel is comprised of picture elements, or pixels as they are known to computer geeks everywhere. The resolution the flat panel display is capable of is determined partially by how many pixels are contained in the display. A typical LCD panel display can range from hundreds of thousands of pixels to millions of pixels, and the higher the number of pixels the better the resolution will be. LCD televisions come in a number of different shapes and sizes, but they are typically designed to accommodate a 16 to 9 display ratio. This ratio makes them perfect for watching widescreen displays like DVDs, as well as traditional television shows.

What are the Differences between LCD and Traditional TVs?

LCD televisions, flat panel computer monitors and other devices have a number of built in advantages, and it is these advantages that have made them such a hit with technology buyers everywhere. Some of the many advantages of LCD technology include:

Brighter display – the displays on LCD televisions are brighter than those on a traditional CRT television, due to the special way these displays work. While a traditional CRT television or monitor uses a tube to create the display, the LCT TV uses pixels, providing for a brighter display.
Flicker free performance – the display of the LCD television or computer monitor will also be free of flicker, since the LCD display will have a constant source of light throughout the entire screen. Once the pixel is turned on it remains on. Contrast this to the design of the CRT television or monitor, which must refresh the screen periodically with a ray of light moving down the monitor or TV.
Low power consumption – another big advantage of the LCD TV is its superior energy efficiency. LCD televisions will be up to 65% more energy efficient than traditional televisions, helping to protect the environment while saving you money.
Ultra slim design – it is of course the thin and sleek design that turns heads and gets the attention of buyers. LCD displays can be as thin as 49mm (just over 19 inches), meaning that these TVs can be placed virtually anywhere.
Wall mountable designs – Many LCD TVs are so thin that they can be hung on the wall as you would hang a picture. It is important of course to purchase a wall mounting bracket that is suitable for holding the weight of the unit.
A Guide to Some LCD TV Terms

If you are in the market for an LCD TV, you will likely hear a number of new, and sometimes confusing, terms bandied about. It is important to understand what these words mean to you, the television technology shopper.

Aspect Ratio – the aspect ratio of the TV helps to determine its suitability for watching movies and television programming in true widescreen format. While the traditional television has always used a aspect ratio of 4:3, i.e. 4” wide, 3” high, the typical LCD television uses an aspect ratio of 16:9, providing a truer widescreen picture perfect for watching DVD and VHS movies, as well as traditional television programming.
Candela – one of those words you may hear from time to time is candela. Put simply, the candela is a standard unit of brightness, and it is equivalent to the number of candles that would be required to produce the same intensity of light. Therefore a rating such as 450 cd/m2 means that it would take a concentration of 450 candles in a square meter area to produce the same amount of light.
Contrast Ratio – the contrast ratio is simply the difference in intensity of light between the darkest black and the brightest white on the display. The higher the contrast ratio the sharper and cleaner the picture will be.
HDTV – high definition television, or HDTV for short, is quickly becoming the standard for television signal technology, and it is important to look for an LCD TV that is HDTV ready.
Inputs – the TV inputs are important if you plant to connect a DVD player, VCR, game console, computer or other device to the LCD display panel. There are many different types of inputs, and it is important that the TV you choose provide a number of different options for getting signals to the device. A TV with a great many inputs will allow you to connect a number of different devices to the TV, greatly enhancing its versatility and its value.
It is also important to make sure that LCD TV you choose has the proper tuner for playing the TV signal you have coming in to the house. Many plasma screen and LCD TVs will lack a built in tuner, meaning that they will need to pick up that television signal from a cable box, satellite TV box, DirectTV signal or other similar device. It is important to make sure you understand the type of tuner that comes with the TV you are considering, and it is important to purchase all the accessories you will need when buying the TV.

Speaking of accessories, it is important to buy only the highest quality component cabling to connect that LCD display to your DVD player, VCR, Laser Disk player, computer or other device. The highest quality cables will provide the best picture and sound quality, which will further enhance the display of the LCD TV you have chosen.

It is also important, of course, to get the very best price you can on the LCD TV you want. The suggested retail price of the typical LCD TV will vary according to a number of factors, such as the size of the display, the thinness of the display and the quality of the manufacturer. It is important to shop around as much as possible, and to read the reviews of all the models you are considering.

Flashlight Buying Guide

Gone are the days when buying a flashlight meant one would automatically seek out Maglite. Whilst recognising the impact and unprecedented success of the Maglite design, LED, HID (High Intensity Discharge) and Xenon technology along with ultra strong casing materials means that the flashlight has evolved to a state where the more powerful the beam does not necessarily mean the larger the flashlight.

When seeking out high performance, reasonably priced lighting tools it is easy to become swamped by the amount of brands on the market. Flashlight technology at the beginning of the 21st century offers a baffling variation of bulb type, body material, body size, power source and price range. This guide is a brief overview of the salient points worth consideration when buying any quality flashlight.

In the same way that feet measure length so lumens measure brightness. The higher the Lumen count the brighter and further the beam will show. Occasionally you may find brightness levels measured in Candlepower or Candelas, this describes a unit of light at source. One Candlepower/Candela is equal to 12.57 Lumens.

Perhaps the most significant breakthrough in lighting technology was the L.E.D. (Light Emitting Diode). The L.E.D. produces light on a molecular level as distinct from a normal bulb, which heats a filament therefore using more energy to produce less light. As a result an L.E.D. will last a lifetime and dramatically lengthen the life of a battery. They do, however, vary in purity. Like diamonds, at the point of production some produce clean white light whereas others have a very slight blue, violet or green tint.

Xenon Lights produce a broad spectrum of light (including infrared) and can be made to have a high maximum lumen output by the inclusion of Xenon gas in the bulb thus enabling light to be produced at a higher pressure, but they are comparatively less efficient users of power. H.I.D technology (High Intensity Discharge) uses a Xenon bulb slightly differently with the addition of a tubular outer bulb and an inner arc tube with a cerium-doped quartz partition in the bulb to block out most ultraviolet. HID torches have lumen output of approximately 500-1000. Lighting technology could be described as a battle between light and heat, as the energy to produce the heat detracts from that which produces the light. The undoubted master is the LED. It makes light without the need to heat a filament, thus lengthening bulb and battery life. However the power from a Xenon bulb can be astoundingly bright yet harder on the batteries.

Casing material has progressed so far as to be almost indestructible if dropped and virtually water resistant in very wet conditions. A good, quality flashlight will invariably have an Aerospace grade aluminium body and a rugged construction and design.

Manufacturers vary in quality and specialism. Surefire have a quality range of Xenon and LEDs with a comprehensive range of accessories. Ledwave produce excellent, powerful and reasonably priced LED and Xenon lights. Nextorch can boast the extraordinary Saint, capable of producing a massive 450 lumens, plus a range of ingeniously, versatile LED, Xenon and rechargeable torches.

Navigating the labyrinth of flashlight production is tricky and ultimately dependant on what job will be asked of it. Lumen output to size ratio, tough hardwearing casing material and bulb / battery life are essential elements to take into consideration when choosing a lighting tool to last and perform over time.

Buyers Guide to Home Theater Projectors

Over the years, I have grown really attached to my home theater system. I must say, of all the rooms in the house, my own little movie theater is the one I could not live without. I am absolutely in love with my home theater system and, if you are anything like me, I am sure you will love yours too. I found, when I was initially building my system, that there was so much information to absorb. Every product out there seemed better than the next, and I found myself unsure about which to buy. Here are a few things to keep in mind when shopping for a new home theater projector.

There are two main types of projectors on the market; DLP and LCD. DLP stands for digital light processing. It was invented by Texas Instruments, and utilizes a microscopic array of over 2 million mirrors. DLP has a higher contrast than LCD, but there are some unfavorable consumer reports that note something called the “rainbow effect”. The “rainbow effect” is noticeable when looking from one side of the screen to the other, and is characterized by a sudden burst of color.

LCD stands for liquid crystal display. These projectors have three distinct glass LCD panels inside; one for each component of the video signal (red, green, and blue). While DLP chips reflect light, the LCD panels allow light to pass through them. LCD projectors produce brighter images, and they are known for having excellent color saturation. In the end, you will be hard-pressed to notice a great difference between the two types of projection systems.

When shopping for a new projector, keep your particular needs in the forefront of your thoughts. As I mentioned above, it is really easy to lose yourself in the minutiae of each particular system. Connectivity is a definitely something to be mindful of. Make sure that you are able to connect all of your components, including your gaming system. Nothing beats playing Halo in real-life size! Contract ratio is another important factor; the higher the ratio, the better the picture will be.

The brightness of your projector is another thing to consider. Light output is measured in ANSI (American National Standards Institute) lumens. You will want to avoid a projector that produces anything shy of 1000 lumens. As you are likely aware, the projection resolution is extremely important. This refers to the number of pixels that can be displayed on the screen. Go for something that is no less than 1024×768, as this will allow you to fully appreciate the depth and quality of HDTV. In the end, you should buy the projector that is in line with your needs and your budget.

Four Easy Steps to Buy a Plasma Flat Screen Television

If you’re looking to purchase your first plasma flat screen television, there are 4 simple steps to insure a pleasant shopping experience.

First, you must decide how much money you want to spend. Take an inventory of your financial situation, and think about what you really want. If you’re on a budget and can’t afford to spend $2,000, you should begin your search with the lower priced models in the 37”- 42” range. Conversely, if you can afford more than $2,000 your screen choice is unlimited.

Second, decide the screen size and manufacturer you like. Plasma monitors are measured diagonally across the screen, as are other television sets and monitors. Plasma screens start at 32″ and increase in size up to 103″. The most typical sizes are: 37″, 42″, 43″, 50″, 61″, and 63″. The best selling plasma televisions are made by Panasonic, Pioneer, Sony, and Samsung.

Third, you should consider buying a plasma television from an online e-tailer. Here are some reasons to buy online:

• Convenience. No need to stand on line, or spend time talking to a sales person.

• Price savings. You save money by not having to pay sales taxes and we’re priced below big box retailers.

• Exclusives. They have a wider selection of plasma models to choose from all the major manufacturers.

Fourth, decide where to mount the plasma television. One of the major benefits of plasma TV is the flexibility they afford in mounting and installation options. Here are a few you might consider:

Flat Wall Mounts are the most common mounting option for Plasma TVs for home or business use. This option is the least expensive and allows the plasma monitor to remain closest to the wall, adding less than 2 inches to the depth.

Tilt Wall Mount is used when placing the plasma TV higher than the desired eye level. A tilt wall mount typically allows 15 to 20 of tilt, depending upon the brand.

Conclusion, buying a plasma television can be an exciting experience that will bring thousand of hours of entertainment if you follow these four simple steps.

Odyssey Batteries and the Odyssey Optimizer

Odyssey batteries are high performance batteries for anyone interested in any type of high speed motorized sporting. One brand has surpassed the rest in offering high performance batteries, and that is Odyssey.

Odyssey, which claims to be the Extreme Battery, offers batteries for motorcycles, ATVs, utility vehicles, and personal watercraft such as jet skis. Odyssey batteries are military grade and can withstand the abuse that comes from high speed motorized sports. While most batteries will succumb to vibration and mechanical abuse, Odyssey batteries do not.

Odyssey batteries are the original rechargeable battery containing lead acid. However, these batteries are sealed so they avoid spilling which is a hazard in traditional “spillable” lead-acid batteries. They are also referred to as sealed-MF, or maintenance free, because they are shipped fully charged and do not require activation.

Odyssey has developed its own tester and charger to ensure the proper maintenance of their batteries. Known as the Odyssey Optimizer, this charger and tester is one of the best of the market for sealed lead-acid batteries. The type of charger required depends greatly on how the motorized sporting equipment is used. If the battery must be discharged rapidly and then recharged rapidly, this requires a different charger than if the battery must stay at a high state of charge with multiple starts and stops.

Odyssey batteries are the way to for anyone involved in motorized sporting. These types of batteries hold all the advantages over their rechargeable counterparts. Though the price can vary greatly, it is well worth the investment to have a reliable and powerful battery.

Emerging Mobile Phone Technologies

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 doesn’t 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 mobile phones in banking transactions where they can send and receive money through phone.

Several high technology features are continuously being researched and applied to mobile phones. 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.

Satellite Communication Security

Communications Intelligence (COMINT) involving the covert interception of foreign communications has been practiced by almost every advanced nation since international telecommunications became available. COMINT is a large-scale industrial activity providing consumers with intelligence on diplomatic, economic and scientific developments.

Various communication intelligence equipments have been and are been designed in order to provide all with a secure communication channel. As satellite communications is growing day by day and is taking the major seat in the global communication network, products are being designed keeping the Security issue in mind.

One of the fast developing technologies in Communication industry provides secure solutions through VSAT Interception, Monitoring and logging systems.

The system is designed for real time collection and traffic analysis of VSAT Satellite Networks. It would provide for total traffic (Voice/ FAX, Data and Multimedia) analysis of TDM/TDMA and SCPC DAMA systems.

Further the system is based on a modular hardware and software architecture, allowing the end customer the flexibility of processing multiple channels simultaneously. The system also provides a GUI for all functions such as equipment control, monitoring, storage etc.

Such a system would be very beneficial and useful especially for the government organizations working for the Defense, as it would have the capability of monitoring the overall target VSAT systems traffic analysis of data, voice and multimedia.

The system is a total integrated and engineered solution for the purpose of monitoring, analysis and processing of multiple target VSAT stations from one remote site.

In case of TDM/TDMA networks, the system provides generic monitoring and processing capability for inbound/outbound traffic.

Such systems provide us with a Secure Gateway for any type of communication, let it be Voice, Data, Fax or multimedia.
