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.
