Digital picture frames will likely completely change the way we display photos in our homes, offices, and public places in a matter of years. This LCD technology is on the path of similar recent ones like flat screen TVs, laptops, and cell phones. As the technology advances, prices become more affordable, and people realize the obvious benefits over the long-standing previous technology, digital photo frames will become ubiquitous. 

Displaying photos in frames is virtually as old as the camera and photography itself. In fact the business and art associated with picture frames has become a huge market itself. Photo frames come in all shapes, sizes, costs, and décor. But until these new digital frames came along, traditional photo frames had one distinct limitation: they are static. 

Digital picture frames build on the concepts of traditional frames and albums but use 21st century LCD technology to move them from static to dynamic. Now by simply transferring pictures in their digital state from your camera or computer to a digital frame, pictures can be displayed in a slide show format in what looks like a traditional frame. 

Digital Photo Frames have become possible through improvements in display technology, storage and memory, and transfer methods. LCD technology has become better and cheaper, so 5-inch, 7-inch, 8-inch, 10-inch, 11-inch, and 12-inch size frames that are crystal clear are possible and affordable. Digital pictures can be stored and transferred via affordable SD memory cards, SmartMedia Cards, Memory Sticks, and USB flash drives. Changing pictures on your frame easily via one of these devices, sometimes wirelessly with select digital frames, is the magic of dynamically changing frames. 

Major consumer electronics manufacturers are capitalizing on the market for these digital photo viewers, including such players as Kodak, Smartparts, and Portable USA, and highly performing frames with many features. Digital frames also come in many décor and colors such from black, brown, white, cherry, espresso, and all kinds of wood. Soon endless new features such as variable frame decors and auto on/off features will become standard. 

It was only a matter of time before the world of picture frames moved into the digital ag

WAAS (Wide Area Augmentation System) was developed by the Federal Aviation Administration to augment the Global Positioning System to improve its accuracy, integrity, and availability. WAAS was originally intended to enable aircraft to rely on GPS for all phases of flight, including the precision approach to airport's within its coverage area. The WAAS system typically provides better than 1.0 meters laterally and 1.5 meters vertically throughout most of the contiguous United States and large parts of Canada and Alaska. This accuracy is capable of provideing aircraft with the precision needed for safe approaches and inflight navigation for all weather conditions. Integrity of the WAAS information is no more than 3 seconds of bad data per year allowing the system to be considerd safe by the FAA for instrument flight rules. 

Although orignally developed for aviation, WAAS is not just limited to the aviation industry, any GPS receiver that is capable of receiving the WAAS signal will be able to benefit from it's correction data, making the GPS positioning more accurate. In fact a WAAS-enabled GPS receiver can even give you directions right down to the lane your car is traveling in (as long as the maping program supports "lane assist" directions). Because the Wide Area Augmentation System is quickly becoming standard in the GPS industry, most new GPS receivers today are WAAS-enabled. Just like with the conventinal GPS, the WAAS system doesn't come with any extra cost or fees to use. All that is required is that the GPS receiver be WAAS-enabled so it can receive and decode the data then be able to apply corrections to it's position. Currently the WAAS service is limited to the U.S.A., Canada, Alaska and Hawaii. Although independant from WAAS, Europe and Asia are working on their own supplemental GPS correction systems. Europe has the "Euro Geostationary Navigation Overlay Service" (EGNOS) and Japan is working on their "Multi-Functional Satellite Augmentation System" (MSAS) . 

How The WAAS System Works 

WAAS uses a network of approximately 25 ground based Wide-area Reference Stations (WRS) in North America and Hawaii, to measure small variations in GPS satellite signals in the western hemisphere. These precisely surveyed ground stations monitor and collect information on the GPS signals and send their data to the three Wide-area Master Stations (WMS). The WMS's generate two different sets of corrections: fast and slow. The fast corrections are for errors that are changing rapidly and are a primary concern to the GPS satellites instantaneous positions and clock errors. These corrections are user position independent, which means they can be applied instantly by any receiver in the WAAS broadcasting area. The slow corrections are for long-term ephemeric and clock error estimates and ionospheric delay information. 

Once these corrections are generated, the Master Stations sends them to two pairs of Ground Uplink Stations (GUS) that transmit the correction messages to a series of geostationary satellites that broadcast their correction data back to earth. Then WAAS-enabled GPS receivers use this information to make corrections to the original GPS signial, giving WAAS-enabled GPS receiver a more accurate position. GPS receiver's use the information broadcast from each GPS satellite to determine their location and the current time. Depending on the GPS device, a GPS receiver only needs to receive a signal from 3-4 satellites (out of the 31 satellites currently transmiting a signal for civilan users) to be able to calculate it's position. In addition to the GPS signal, a WAAS-enabled GPS receiver can also receive the geostationary WAAS satellite signal. 

The two different types of correction messages from the WAAS system (fast and slow) are used by the GPS receiver in different ways. The fast type of correction data includes the corrected satellite position and clock data to determine its current location using normal GPS calculations. Once an approximate position fix is obtained the GPS receiver begins to use the slow corrections to improve its accuracy. Slow correction data Includes the ionospheric delay. When the GPS signal travels from the satellite to the receiver, it passes through the ionosphere. The receiver calculates the location where the signal pierced the ionosphere and, if it has received an ionospheric delay value for that location, it corrects for the error that the ionosphere created. Unlike the fast data, the slow data doesn't need to be updated frequently because the ionosphere conditions don't change rapidly. While the slow data can be updated every minute if necessary, they are only updated every two minutes and are considered valid for up to six minutes. 

Limitations of the WAAS System 

(1) The WAAS system is currently only available to United States and large parts of Canada and Alaska but there plans to expand the system to other countries and continents. (2) Because the WAAS broadcasting satellites are geostationary causes them to be less than 10° above the horizon for locations north of 71.4° latitude. This means aircraft in areas of Alaska or northern Canada may have difficulty maintaining a lock on the WAAS signal. (3) In order to calculate an ionospheric grid point's delay, that point must be located between a satellite and a reference station. The low number of satellites and ground stations limit the number of points which can be calculated. (4) Aircraft conducting WAAS approaches must possess certified GPS receivers.

Here's the list of some common mistakes for buyers and owners of HDTV sets. 

1. Keep chemicals away from TV, ammonia in Windex can damage coatings. Liquids sprayed on the screen can seep in between the bezel and panel and cause all kinds of problems. Best to use a damp cloth preferably not wood-based paper products like newspaper or paper towels which can create tiny scratches. 

2. Don't buy a Plasma TV if you're going to be watching it in a brightly lit room with a lot of windows. Unlike LCD TVs plasma TVs have thick glass panels which can create lots of glare. On the other hand, don't be afraid of Plasma "burn-in" which was a more common problem on older Plasma TVs . Most of today's Plasma TVs have circuitry to prevent burn-in or ghosting. 

3. Don't pay too much attention to those formulas that use room size to determine screen size. Buy the biggest TV that fits with your furnishing. Also keep in mind if you don't have an upconverting receiver or upconverting DVD player, a lot of programming that comes from DVDs and standard def programming shows up on your screen with big black borders around it so a bigger TV might be better if you're going to be watching a lot of standard def programming. 

4. Don't turn down a great deal on a 1080i TV. Even though we recommend buying a future-proofed 1080p TV, Bruce Berkoff of the LCDTV Association points out that it is difficult to tell the difference between 1080i and 1080p on a set capable of displaying all the pixels. He adds, "If a TV is rated at 1920 x 1080 resolution it shouldn't matter if the program is in 1080i or 1080p." Currently none of the programming coming in over the air, on cable, or satellite is 1080p. More so, you can't really tell the difference on anything smaller than a 37 inch TV or if you sit far enough away from a larger set. 

5. Don't leave the brightness up too high. Many TVs ship with the brightness setting 21 in "showroom" mode. In a normally lit living room a lower brightness level is perfectly adequate and saves energy too. If you want to get the most out of your HDTV set, you should consider having it calibrated by an expert like someone from Geek Squad or do it yourself with a DVD like Digital Video Essentials. 

6. Don't get fooled into buying expensive add-ons from the salesperson at your local big box retailer. Most HDMI cables work just fine for most programming. The one reason to spend the extra money is for a high speed (Category 2) capable cable used for "Deep Color," and lossless audio. 

7. Pay Attention to Audio. You may think the sound on your TV is just fine but if you haven't heard 5.1 (or more) surround sound on a quality audio system you haven't experienced HDTV. Some things to keep in mind when shopping for an audio system are; be cautious when buying speakers from a brand not necessarily known for speakers like some major consumer electronics brands (you know who they are), make sure you listen to the speakers before buying them, don't hide the speakers in furniture, and make sure the receiver has enough ports for future expansion. 

Now that you have some general idea of what to look for and what to avoid, the last step in finding the perfect TV set for your home is to read reviews. Good places to start are with known vendors like Vizio, Toshiba, and Samsung.

It is obvious, we are absolutely in the Computer Age. that it was the norm to be without a computer at home, now the opposite is typical. Apparently, each home has at least one computer, and should you admit to not having one, the likelihood is no one will believe you! 

While the first computers were big, room-sized goliaths capable of only very limited routines, now we are empowered with micro machines that multitask easily as music players, cameras, web browsers, phones, word processors and email clients. 

The standard used to be that you had a desktop computer at home or the office to manage the important tasks, a cellular phone that could merely make and take calls, and a large Netbook with brief battery life that would just allow you to check your email or work on a spreadsheet or document. 

But, that is not the fact any longer. Today’s Netbooks are sleek, lightweight, and extremely varied, with longer battery lives and even built-in wireless modems to allow the user to access the Web anywhere a ‘hotspot’ is found. 

Depending on what you want, you can acquire a Netbook to satisfy your desires. You can even personalize your ideal Netbook with just the programs you want. 

But even better than being able to find or personalize your Netbook is the fact that the costs of the movable machines are sinking speedily. Where once they were more expensive than a more functional desktop computer, even as much as $3000, today Netbooks having plenty of memory and powerful programs can be purchased for less than some desktops. 

>From writing the next great American novel to surfing the Web, for watching movies or making your own videos, to managing your household finances and sharing your thoughts online, current Netbooks are the complete answer to daily computing as well as the necessities of most commercial enterprises. 

With the amount of choices available and the reasonable costs, there is no longer a need for anyone to be shackled to a desk to use the ability and velocity of a high-performance machine.

This camcorder fits comfortably in your pocket and is easy to use with one touch recording and a flip out USB port that plugs directly into your computer and charges the lithium ion battery. 

The Flip MinoHD comes in the minimalistic packaging that all other Flips come in. This packaging remind me of the iPhones it is very similar. Hopefully Flip will rectify this situation in future incarnations of the MinoHD. Basically the MinoHD camcorder is all about pushing the red button to start and stop recording and hit the playback button to see what you recorded and thats pretty much it. 

It weighs a mere 3.3oz and is smaller than my mobile phone. Flip camcorders have earned a reputation for high quality video and MinoHD combines that signature Flip quality with the latest in HD technology. Its 4 GB of built in memory lets you capture an hour of brilliant HD video even in low light situations. The MinoHD does much better when held steady (Amazon is currently bundling it with a mini tripod for a reason). The camcorder also has some focus issues such as choosing the ground rather than the animal scampering across it and you can't get too close to your subjects or they will be out of focus. 

The Flip MinoHD's intuitive controls compact package and quality video capture that now goes to HD make it an appealing competitor among camcorders that can come along for any ride. While that means you have one less USB cable to carry around it causes the camera to dangle awkwardly off the computer when connected and as a result the MinoHD may block other ports. Overall I think the flip out USB connector is a good thing annoyances aside. So you lose that option with the MinoHD but still good battery life overall. The camera does react a little slow though taking 3-4 seconds to power up and be ready to shoot. 

The Flip Mino HD billed as the worlds smallest HD camcorder is worth its weight in gold. If I had to choose one con for this camera I would say that I wish they would've added an external microphone jack to it but thats really reaching. Minor issues I can handle a single dud unit I can understand but a product that consistently fails at it sole function is completely unacceptable. About the size of a small cell phone the MinoHD can easily be controlled with one hand. Theres no menu to worry about. 

You have to charge it in a few hours on your computer USB port and it will run out of hours recording time long. The flip out USB arm plugs directly into your computer to launch built in FlipShare software or for simple file transfer. The included software provides tools to save and organize your videos, edit individual clips, make custom movies, email your videos, and upload them for sharing with friends. Simply flip out the USB arm plug in to any PC or Mac and start sharing your videos in mere seconds. Upload them to YouTube, MySpace, and AOL Video with the click of a button. 

The size of the flip allows for more spontaneous captures also as it takes about 3 seconds to take out of your pocket turn on and press record. No unpackaging, no complicated setup, and no lost footage opportunities. Also the screen is so small that its difficult to see what you're recording which is necessary when the video is in 720p. And as you're recording you can get a sense of how the finished product will appear on a 1.46 inch LCD display that looks clear even in daylight.
