Multiple HDMI Connections
HDMI stands for High Definition Multimedia Interface and allows you to get the very best out of High Definition pictures and sound. Choosing three HDMI connections means that you can connect to SKY HD, and HDMI DVD player and a games console simultaneously. With this in mind you may choose to purchase an HDMI CEC. This is a Consumer Electronic Control that allows you to control all of your components through one TV remote control. It is preferable, when using this system to use same brand product, however, mixed brand products can still be controlled by a single remote on a basic level.
100HZ Technology.
100Hz is the perfect choice when viewing sports of fast action movies. When you consider that your average television displays at only 50Hz it’s easy to see why the picture can judder, especially when it is slowed down. With 100Hz and extra frame is added which is an average of the frame either side of it, these frames are then added back to the real time footages creating a clear, judder and blur free motion, essential when you are looking for perfection in fast moving TV.
Other Technology
With today’s Techno terms it can be very easy to become totally confused as to what else to buy when you are considering upgrading to a TV, Home Cinema system and DVD. Let’s look at a few examples, why for instance would you want to by a Component lead? Well, this lead will produce a better analogue picture from your DVD player than using a standard lead. Choosing a TV with DV input means you can add a digital devise such as a video camera and then record from that devise straight onto a DVD. S-video is a high quality analogue video connection cable and a scart lead is an Analogue connector that transfers pictures and sound to your TV.
Some other terms
Aspect ratio is the ratio of image width to image height. Auto tuning will automatically tune in aerial received channels. A digital Comb Filter will separate combined colour and black and white picture information resulting in a much sharper picture. Progressive scan is where all horizontal lines of the frame are shown in one go, this method delivers a superior picture from a DVD or video player. Especially useful for a household of different televisual tastes is the Picture in Picture system which allows programmes from different inputs to be viewed simultaneously, one on the full screen and one in a smaller window, so now you can watch the match and your favourite soap at the same time!
A few final terms.
Dolby digital 5.1 allows you to hear all five channels of sound via a home cinema system for a true surround sound effect. Fastext is an updated version of teletext that uses coloured keys on a remote as short cuts to the pages. Freeview is a free digital service of 41 channels that you can view via an integrated digital television or a separate set top box. And Finally HDTV is High Definition television broadcasting that provides exceptional picture quality and true surround sound.
We hope that this has helped you find your way around some of today’s technology. Now all you have to do is choose your system and sit back and enjoy the superior viewing now available to you at 1staudiovisuals very special prices. Enjoy!

Laser technology is used in almost every scope of life, from the miniscule lasers in CD players to the lasers used to scan groceries in the checkout line to the massive lasers in aeronautics design. The discovery of laser technology and the subsequent building of ever-improving lasers have benefited the human race tremendously, particularly through medical advances. Medical lasers cause medical procedures to be quicker, better, and easier than their traditional counterparts. The only drawback is increased cost.
In 1917, Albert Einstein was the first person to suggest the basics of what would become lasers, by discussing the theory of Stimulated Emission, which is a type of electron transition in which a photon is emitted from an atom causing a chain reaction with other atoms to repeat the action. In fact, the word laser is an acronym for Light Amplification by the Stimulation Emission of Radiation. Charles Townes, an American physicist, further developed the idea with microwave (invisible) light in the mid- to late-50’s and Theodore Maiman built the first working optical (visible) light laser in 1960. Improvements and variations on hundreds of kinds of lasers continue to be made since the 1960s. Those involved in quantum mechanics have been studying some form of lasers, either in theory or in reality, since the 1920s. Uses for laser technology are widespread and are included in such important fields as medical/surgery, communications, design, manufacturing/industry, and research.
Medical/Surgery
The advancement of medical lasers has vastly improved the ease and success of surgery. The cost, however, is greater than that of other treatments, though scarring is much less with lasers and lasers work much more quickly than older surgical options. Incisions are more precise and easier to control. Some medical areas in which lasers have deeply refined treatment options are in laser eye surgery, oncology, neurosurgery, cardiology, dermatology, veterinary surgery, and dental surgery.
Communications
Televisions, telephones/ cellular phones, and computer systems all benefit from the use of lasers. Lasers are able to carry the huge amounts of channels and frequencies required by these high-tech devices. Lasers have proven the best communication device to have in the space age.
Design
Lasers have transformed the world of design by making it possible for designers to perform with precision that was previously unavailable. Lasers are used to design digital and three-dimensional objects with much more ease and accuracy through scanning, cutting, copying, and digital archiving. From designing a building to designing landscape, lasers prove to be the best option for fast and easy design.
Manufacturing/Industry
Lasers have improved the manufacturer’s ability to produce tenfold. For example, with a laser cutter, a clothing manufacturer can have fabric patterns cut much more quickly and more accurately in no time. A jeweler has much more precision on his side when employing lasers to work on fine gems. Airplane designers can construct an aircraft much more efficiently and with greater results using laser technology.
Research
The use of lasers in research enables scientists to uncover much more detail and detect very slight movement when studying matter. The lasers can be tailored to only respond to certain colors or movements and, in that way, they provide much more specialized work in research environments.
The world of laser technology is always expanding by producing new applications and ways to benefit people. The dependence that the modern culture has on lasers is amazing considering that it was not prevalent until the past forty years.

And doing so through an online Information Technology degree program is a convenient and cutting edge way to gain the tools you need in this fast-paced field.
Information Technology professionals have become one of the biggest assets to any organization that relies on computer networks. IT professionals are troubleshooters when systems go down; they are lifesavers when files get lost. Information Technology is a hands-on profession that requires skill and training. Having an Information Technology degree will show an organization that you have the tools to help keep their networking machine running smoothly. And if you already have an IT degree, continuing your education is a great way to keep up with new technologies, and achieve your greatest career aspirations.
There are many advantages to earning an Information Technology degree online. Proximity is not a factor in choosing the right college or University for you. Attending classes and submitting coursework online eliminates the need for commuting or relocating, so you can keep working while you attend school. Convenience is another factor in earning a college degree online. A college may be able to offer many convenient sections of certain courses, allowing you more choices as to when to attend classes. Night and weekend sections of courses are usually offered as well, which is ideal for you if you work full time and/or care for a family. Further, if you are considering returning to school after several years, seeking your Information Technology degree online is a great way to ease into the routine of class work and projects again, and can reduce the pressure of feeling the need to fit in with younger students. In addition, who wouldn’t find it appealing to attend college from the comforts of home?
Whether you are seeking a degree (Associate’s, Bachelor’s, or a graduate degree) or if you are seeking certification in specific skill areas, there are several options if you are considering receiving your Information Technology degree online. There are several online-only institutions that are fully accredited and offer many degree and certification programs. Accreditation is an important factor to consider in choosing an online college.

Understanding how fiber optics are made and function for uses in everyday life is an intriguing work of art combined with science. Fiber optics has been fabricated from materials that transmit light and are made from a bundle of very thin glass or plastic fibers enclosed in a tube. One end is at a source of light and the other end is a camera lens, used to channel light and images around the bends and corners. Fiber optics have a highly transparent core of glass, or plastic encircled by a covering called “cladding”. Light is stimulated through a source on one end of the fiber optic and as the light travels through the tube, the cladding is there to keep it all inside. A bundle of fiber optics may be bent or twisted without distorting the image, as the cladding is designed to reflect these lighting images from inside the surface. This fiber optic light source can carry light over mass distances, ranging from a few inches to over 100 miles.
There are two kinds of fiber optics. The single-mode fiber optic is used for high speed and long distance transmissions because they have extremely tiny cores and they accept light only along the axis of the fibers. Tiny lasers send light directly into the fiber optic where there are low-loss connectors used to join the fibers within the system without substantially degrading the light signal. Then there are multi-mode which have much larger cores and accept light from a variety of angles and can use more types of light sources. Multi-mode fiber optics also use less expensive connectors, but they cannot be used over long distances as with the single-mode fiber optics.
Fiber optics have a large variety of uses. Most common and widely used in communication systems, fiber optic communication systems have a variety of features that make it superior to the systems that use the traditional copper cables. The use of fiber optics with these systems use a larger information-carrying capacity where they are not hassled with electrical interference and require fewer amplifiers then the copper cable systems. Fiber optic communication systems are installed in large networks of fiber optic bundles all around the world and even under the oceans. Many fiber optic testers are available to provide you with the best fiber optic equipment.
In fiber optic communication systems, lasers are used to transmit messages in numeric code by flashing on and off at high speeds. This code can constitute a voice or an electronic file containing, text, numbers, or illustrations, all by using fiber optics. The light from many lasers are added together onto a single fiber optic enabling thousands of currents of data to pass through a single fiber optic cable at one time. This data will travel through the fiber optics and into interpreting devices to convert the messages back into the form of its original signals. Industries also use fiber optics to measure temperatures, pressure, acceleration and voltage, among an assortment of other uses.

If you’re a tech head like me then choosing the right bits if kit to take with you traveling is a very important decision. I like to be wired into the world and well entertained when I am sitting on a 12 hour train ride or some hotel room on a stopover – it makes the time pass much faster and I can actually get some stuff done. But what should you consider packing for your trek and how can you possibly fit it all in?
As with any type of packing for travel, selecting which pieces of technology to take with you should be determined by weight, size and utility. Less is more! That means taking the smallest and lightest of everything you need.
If you want some computing power on your travels, then a laptop would be the obvious choice. But do you need all the computing power that a laptop can give you or could you escape with just using a tablet or a PDA? When you are lugging around 6 pounds of laptop for miles and miles, the thought of a nice little 200 gram PDA become mighty attractive. If word processing the main reason for taking a computer then consider a PDA with a fold out keyboard. You will be thankful for the weight and space it saves. Alternatively some tablets are more powerful than many laptops and offer the same software options so that might be one other consideration.
Your camera is another consideration. Do you need the 35mm SLR with 4 spare lenses? Unless you are going somewhere that justifies the weight of that, then you might be better off with any of the myriad of small digital cameras available on the market. Many of the newer models are up around the 6 megapixel and above mark meaning the quality of shots is getting very good.
If you desperately need music, then consider any type of MP3 player that can double as a digital photo storage device. iPods are a good choice and nice and light and the fact that you can store any data such as digital photos on them means you can cut down on packing other storage devices.
One of the big things that you are really going to need for all of your gadgets is insurance. Aside from the fact that a person with a lot of gadgets has a lot more to lose when they get robbed, stuff also gets knocked around a lot when you travel. Make sure you get insurance that covers you for the cost of a new replacement of anything that is lost, damaged or stolen.
A few minor considerations at the time of purchase can save a traveler a lot of heartache with gadgets. If you can describe your gear as small, light, useful and insured then you should have a pleasant trip!

Dateline: Tuesday, July 13, 2010
Location: Teterboro, New Jersey
The Schedule: N714JA, a Gulfstream V in Jet Aviation’s Private Fleet, is scheduled to take off at 0830 for LAX. Crew of three with fourteen pax.
Backgrounder: Kay Hughes, flight attendant for today’ s non-stop coast-to-coast flight is busy checking her catering order and prepping the cabin. Bob Harmon is the captain and Jeff Mortowski is his first officer. Both are situated in the cockpit going over the pre-flight checklist. The pax are from various companies in the New York area or individuals on personal business who have bought seats on his flight.
The Story: Kay woke up with a start as the alarm on her clock radio blared. Reaching across her pillow, she noticed the time, 5:15, and hammered the snooze button in the hopes of grabbing another five minutes of sleep. Tired as she was, her mind began to race as she considered the day ahead. In less than four hours she would be enroute to L.A. with an aircraft full of passengers. Slowly the thought of additional sleep became less important as she considered all that she had to do before leaving Teterboro. Quietly she slipped on her robe and slippers, poured herself a cup of coffee, and slinked into the shower.
As Kay walked across the tarmac, she saw the fuel truck pulling up to her aircraft and the caterer at the gate waiting for a security clearance. It was 6:48 and already she could feel the heat lifting off of the pavement. Another scorcher she thought; at least L.A. will be cooler.
Kay greeted Jeff who was busy overseeing the fuel delivery; she then climbed onboard the G-V and gave a similar greeting to Bob who was occupied with updating paperwork. Bob finished what he was doing and briefed Kay with the day’s schedule. Minutes later Kay turned to assist the approaching caterer with the day’s order. Within the hour, the first of the passengers began to arrive. Each sat in the lobby of the FBO waiting to be boarded. At precisely 8:00 a.m., Kay left the aircraft and walked down the ramp to the FBO. She whispered to the waiting security agent who signaled to the FBO customer service representative to make the boarding announcement. “Ladies and Gentlemen, Jet Aviation Flight #001 departing TEB for LAX is now boarding. Please present your identification card and boarding pass to the security agent. Once you are cleared, you will be boarded. Thank you for flying Jet Aviation and enjoy your flight.”
Kay turned and left the FBO and walked back to the aircraft. Both pilots were onboard completing their preflight preparations. Kay stood at the bottom of the steps leading up to the aircraft waiting for the security agent to bring the passengers to the plane. She knew that with fourteen passengers the security clearance would take a bit longer than normal.
Kay considered waiting inside the cabin to keep cool, but knew that it was important that she greet the passengers at the base of the steps in case one of them needed assistance climbing up.” It must already be 85 degrees out here,” she thought as she watched the heat vapors rise off the pavement.
After what seemed like an inordinate delay — Kay’s hair was slowly losing style in the heat — Bob poked his head out of the cockpit and said, “Sorry for the delay, but we caught another one.” Startled, Kay stammered, “You mean one of the passengers failed security clearance?” Bob replied, “Not only that but he is on the FBI’s wanted list of suspected terrorists. The remaining passengers checked out okay, but we’ll be delayed until the agents finish interviewing them to see if they knew the guy.” Despite the heat, Kay shivered as she thought of the potential chain of events a terrorist onboard the aircraft might unleash.
Her fears gradually subsided when Jeff reminded her that the VOICE RECOGNITION IDENTIFICATION TECHNOLOGY (VRIT) unit in the FBO was flawless in the nearly six months of use. Over that time, twenty-six people with a criminal element were pulled, most of whom had been charged previously with petty crimes [such as tax evasion] and were either on the run or would be in violation of their parole restrictions had they left the state. Today marked the first time that a suspected terrorist was caught and as the squad car sirens wailed, Kay knew that this day would be anything but normal.
The above account is fiction, but it pre-supposes a couple of things that could occur in the intervening years that would bring about similar results, i.e., additional and more widespread terrorist attacks being a primary consideration. In addition, a change in the way we do business, i.e., selling seats to individuals instead of selling the entire flight to a company or an individual would have to occur — no longer would you have a lead passenger who could identify all of the other passengers. VRIT is now within reach and will, more than likely, become the norm of the day. Essentially, it works this way: a person speaks into a device that immediately matches the voice pattern with one in the database. The database identifies the person and when a match is made, the person is cleared [unless the database turns up a warrant for their arrest].
Naturally, in order to get onboard a flight we would require passengers to be part of that database. This could occur if VRIT becomes as mandatory as holding a social security number or a driver’s license. Foreign nationals would have to be keyed into the same system to make it work, so the potential for a worldwide Orwellian-type system would be great.
Recently, I had the opportunity to meet with Russ Cooper, a managing partner with COMPUTEK, a Wall Street company that has developed the latest generation of VRIT. He shared with me that both the FBI and CIA use an older generation of VRIT and his company is marketing the current one. Their customer base potential is impressive: government agencies, security firms, airports, airliners, automobile manufacturers, you name it. Wherever a positive i.d. on a person is needed, their technology might be utilized.
According to Russ, the technology is fail-safe. When I mentioned that a voice impersonator like a Richard Little type could sneak by, he claimed that VRIT would still know who he was even with the “Richard Nixon” voice. Apparently, voice patterns are distinguishable even when disguised.
We did not discuss “price” as he was not marketing his product directly to me. I can only imagine that the costs involved would be significant, but then I began to think that they could possibly be offset by lower insurance premiums if insurance companies see the benefit of “guaranteeing” passenger security.
So what role could the flight attendant play in utilizing VRIT? Perhaps in lieu of a security agent [especially in out of the way places like Bozeman, Montana], a VRIT unit would be assigned to your aircraft — much like a cardiac defibrillator monitor — and you would greet each passenger as they boarded the aircraft. Before the aircraft could be cleared for takeoff, the passengers would speak into the handheld VRIT and be given a security clearance on the spot.
Let’s return to our story and amend it with the security check being placed directly in the flight attendant’s hands:
Kay walked down the G-V’s steps carrying her mobile VRIT device and waited as the passengers exited the FBO and made their way to the aircraft. She announced, “Welcome onboard Jet Aviation flight #001 bound for Los Angeles. Please speak your name into the VRIT unit. Once you have been cleared, you may proceed up the steps. The first officer will take your boarding pass and you may be seated. If you need additional assistance, the captain will be glad to help you.”
One by one the passengers filed by, stating their name and waiting for the green clearance light to flash. As they spoke, a signal was transferred to an orbiting satellite and then beamed to VRIT headquarters in Washington, DC. As the last of the passengers approached, Kay continued to greet each one and wait for clearance. Finally, when all passengers were cleared, she climbed the steps and had both pilots speak into the VRIT unit. At last, Kay placed the unit in the First Officer’s hands in order to have him run clearance on her. Kay cleared her throat, spoke her name, but after an extended pause, the VRIT beeped loudly and signaled red. The color in Kay’s face drained away and she turned to flee. Within moments several arms reached forward to apprehend her as sirens wailed in the background.
All she could think about was running away…
Startled, Kay awoke from her dream as the snooze alarm blared away.

If you are in the market for a computer, there are a number of factors to consider. Will it be used for your home, your office or perhaps even your home office combo? First off, you will need to set a budget for your new purchase before deciding whether to shop for notebook or desktop computers. Many offices use desktop computers because they are not intended to be moved around a lot. In addition, affordability often plays a large role in someone’s decision as to whether to purchase notebook or desktop computers.
While you are shopping around, it’s important to keep in mind some of the benefits that go along with owning different types of computers. To that end, this article provides five important reasons to purchase desktop computers.
- Desktop computers are typically much more affordable than notebook computers. With notebooks, you are paying more for the convenience of portability. For as little as $299.00, desktop computers can be purchased from one of the leading manufacturers and a notebook computer for as little as $499.00.
- Unlike notebook computers, replacing a keyboard, mouse, speakers or even a monitor does not require having your computer serviced by a professional repair shop. Because notebook computers have everything built in, including the aforementioned features, it is more difficult to replace a keyboard or monitor as opposed to desktop computers, which operate on external connections.
- In the event of an unlawful entry into your home, desktop computers are not as likely to be stolen because of their weight and bulk. Notebook computers, on the other hand, are small and portable. This, alone, makes them more appealing to a thief than desktop computers.
- Desktop computers are stationary by nature. Unlike a notebook computer, which can easily be moved from room to room, they are less likely to be dropped or broken because they are not moved as often.
- The vents on desktop computers are located on the back of the tower, which allows for proper ventilation that will help to prevent the computer from overheating. Notebook computers, on the other hand, feature only one vent on the back with the remaining underneath the base. If placed on a table, the air vents can become blocked and the computer may overheat. If prolonged use leads to overheating, damage may result.
When choosing from the many desktop computers on the market, always make sure that you purchase from a manufacturer who has experience in creating computers. Even though they are more affordable than notebooks, desktop computers are not cheap. With an investment that involves several hundred dollars, you will want to consider the length of time the manufacturer has been in business, their reputation with customers and their warranty.
Additionally, when choosing any system, including desktop computers, always look at the potential for future upgrading. As you grow, you will want your computer to grow with you and a part of that will include a slight upgrade from time to time. This is the only way to get the best use of your desktop computers and make sure that your investment is one that lasts for years to come.
