Class, Let’s Review The Xd2200 Sanyo LCD Projector

The PLC-XD2200 Sanyo LCD projector is a portable XGA (1024 X 768) multimedia module that produces first-rate color for nearly the lowest price in its class. It’s your basic no-frills projector, lacking digital input and PC-free or network presentation ability with only a single watt speaker built-in. But if you are primarily looking for an attractive price, portability and fantastic color rendition in every image mode, then the XD2200 has got you covered.

Setup is a snap thanks to the XD2200’s “Auto Setup Function”. This feature automatically performs keystone correction of the input signal by detecting the inclination angle of the device. This model is extremely power efficient when placed into standby mode, drawing a mere 0.4 watts in comparison to the 2-3 watts drawn by other projectors. Another sweet feature is the estimated 6000-hour lamp life you will achieve when using Eco mode. Since a brand new lamp can amount to almost one-third of the cost of a new projector, it helps to know that if you can operate mostly in Eco mode (which is in excess of 1000 lumens), you will receive a few eons of projection time out of your bulb.

You would be correct to assume based on the size and weight of the XD2200 that it is a remarkably portable device. Unlike much of its competition, this Sanyo LCD projector does not come with its own travel bag. Perhaps this is because it easily fits into most soft briefcases.

If a simple and clean appearance is appealing to you, the XD2200 will be a delight. Beginning at the front panel, the recessed lens is located on the left side of the front face, keeping it protected even in the absence of the tethered lens cap. Right behind the lens, in the recess above the projector face, you will conveniently find the focus and zoom adjustments. You also have an infra-red receiving eye to the left of the lens. On the other side of the lens you will find two stacked air intake vents. A removable filter on the bottom of the projector, which slides out from the front, is located in the bottom intake vent. There is a single front height adjustment foot in the middle with the standard push-button release. Fine-tuning of the height adjustments are done by screwing the foot out or in. A small downside is fact that you have no adjustment feet in the rear, so make sure you’re using a fairly level surface for table mounting.

Taking a look at the top of this Sanyo LCD projector from the front face, you will see a cover in the right rear for accessing the bulb. This allows for simple lamp replacement if the device is mounted from the ceiling, since there is no need to dislodge it just to replace a lamp. In the left back corner you have a control panel with the most-commonly used functions, including power indicators, lamp status and warnings if the unit has any problems such as overheating. You have you buttons for Power, Auto Setup, Input Search, Auto PC adjustment, and Auto Keystone.

The next set of buttons you have are for bringing up and selecting from the on-screen menu, as well as menu navigation buttons. The Left and Right menu navigation buttons will additionally perform as your Volume Down and Up respectively.

The built-in one-watt speaker is found on the left side (if you’re facing the front of the unit), toward the front. The power cord connector is located on the right side, toward the front, as are the two heat exhaust vents and the screw for opening the lamp cover.

Continuing on to the back panel from the left, you will find two more heat exhaust vents. To the immediate right of that are an RS-232 port and a Kensington lock. Then you have your two computer input terminals. This first input will also act as the input for component video and S-video. You may need to purchase the appropriate adapters. The second input can serve dually as a monitor output when not being used as an input. In this same area you have your stereo audio inputs, one PC audio input, a composite video input and an audio output which is adjustable for output volume level from the remote. Lastly, there is a LAN jack for a network connection. Below that is another air intake vent with a slide-out dust filter.

It’s worth noting that even though the lamp cover is smartly located on the top of the projector, the two dust filters may be a bit tight to remove for a ceiling mounted unit. Since filters should be removed for cleaning way more often than the bulb will need to be replaced, you may want to take this into consideration if you want to mount your XD2200 Sanyo LCD projector on ceiling.

You can check the XD2200’s video display capabilities by the DVD playback on your laptop computer. Beginning in Real mode, you can review scenes from your favorite movies like “Batman Begins” or “The Swan”. In either case, you will find that skin tones are quite natural and the overall color balance is quite solid. Sometimes a low contrast ratio and reduced black levels may occur if you are viewing darker scenes. The gamma adjustments should help with black levels. This is hardly atypical for a projector in this class, much less one in the price range of the XD2200. Since it is often preferable to have more accurate colors, the solid color reproduction of this model makes it an ideal selection for video presentations in the classroom. So if you have a video presentation that contains audio, you may want to consider using some external powered speakers. The built-in 1-watt speaker of the XD2200 Sanyo LCD projector is not intended to achieve a volume level required by some larger conference rooms or classrooms.

Protect Your Data and the Environment Through Drive Recycling

I find myself sitting in the second floor of a huge public library in a good-sized college town. I came here for the quiet and solitude, for a change of scenery that was different from my home office. What I got was an overwhelming sense of how technology has changed our lives. Even though I am sitting amidst long, tall rows of books on every conceivable subject, I look around and see folks at tables, clicking away on laptops and netbooks.

This particular library has over sixty public computers scattered throughout its two-story repository. There is even a computer lab for patrons to use. In addition, I am connected to the virtual world outside through their free Internet WIFI connection. Do you remember the card catalog cabinets and the Dewey Decimal System? It’s all on computer now, thank goodness. You don’t get just a shelf location; you get a map!

As I gaze out the window to the street below, I see college students walking, or rather, dancing down the sidewalk with tiny headsets stuck in their ears, harnessed to a tiny mp3 player. I think back to my vinyl LP record collection that took up two shelves that were six feet long. There is more music stored on those tiny devices than I could ever fit in my house.

When I walked in the door to get my new library card, I was advised to put my cellphone on silent. I can remember back when our telephone was on a party line and we had to wait our turn to use the service. These days, the tether of the handset cord to the phone is gone; we have free rein to roam anywhere in the world and still be able to phone home.

Unfortunately, those technological advances that have enriched our lives have a downside: electronic waste. According to a recent Environmental Protection Agency study, our electronic waste is having a negative impact, not just locally, but globally. In the United States, the EPA estimates that 1% of our municipal waste streams are composed of electronic waste. They also estimate that 30 to 40 million computers will be scrapped each year for the next couple of years as they reach their end of usable service. Technology and software advances are making computers obsolete, almost before they are sold off the shelf.

Recycling old computer parts, such as hard drives, may not eliminate the problem, but it can surely help. Data loss that requires a hard disk file recovery service often means that the hard drive is toast. Physically damaged drives can be repaired enough to perform NTFS file recovery, but they are no longer reliable. The next time you need internal or external hard drive data recovery, look for a company that has a hard drive recycling program. Those folks care, both about your data and about our environment.

Using an Inversion Table for Back Pain and Overall Stress Relief and Relaxation

When done properly and regularly, using an inversion table can give significant relief to back pain, particularly lower back pain, and provide stress relief and overall relaxation. The inversion table allows a person to comfortably and safely have varying degrees of being head down and feet up. Some people may feel uneasy with the idea of being inverted, but they can allay that fear by starting at a very small inversion angle and working up to more and more as the comfort level increases. While on an inversion table, the person is in complete control of the amount and speed of the inversion. The inversion table works on the pendulum theory and whatever end the most weight is on is the end that will tilt. The table is adjusted to the height of the person and when he gets on the table, leaning back and raising and lowering the arms can control the amount and rate of inversion. Also, bending the knees changes the center of gravity and brings the table back to upright position. There is a strap, or tether, that can control the maximum inversion desired. Having another person available until one become familiar with the inversion table may be advisable.

Everyone has Mother Earth’s constant gravitational pull on the body, so inversion is actually prudent for most anyone and can promote overall health and stress relief. That constant downward pressure, over time, even without evidence of back problems, serves to pull down on the body’s muscles and spine. The inversion technique simply allows the whole body including the muscles of the legs, spine, shoulders and neck a momentary reprieve from the constant downward pull as well as improving circulation helping the skin and hair. The gentle stretch that it gives the body is unparalleled.

The fact that the inversion table is primarily sought by people who suffer back pain is not surprising. Back pain has many different causes including stress, injury, nerve problems, and disc compression. The back pain can rank from a mild annoying discomfort to being severely debilitating. Regardless of the cause of the back pain, muscles tighten and inflammation may be present which decreases the amount of blood flow to the affected area. The decrease in blood flow diminishes the delivery of oxygen and nutrients to the area and also diminishes the release of waste from the area. Thus the problem can keep compounding itself. If a disc is ruptured or ballooning out causing pain, the pain can be excruciating.

Using the inversion table allows the muscles in the back to have a gentle stretch promoting increased circulation, allows the discs between the vertebra to have the pressure released and move back into a more normal position, and allows the spinal column to realign itself if one of the vertebra has moved slightly. Often times, some relief, if not total relief, is obtained almost immediately. Depending on the cause of the back pain, some people, with regular sessions, may be able to obtain the level of relief they desire. Even when the back pain is relieved, regular sessions on the inversion table is advisable to keep the back muscles and spine from the deteriorating effects of gravity.

The amount of inversion chosen is totally individualized. Amazingly, even small degrees of inversion can be very beneficial so one can start with a 20-30 degree of inversion and work up as desired. Some people like the feeling of being totally inverted and some don’t. The body does not have to be totally upside down to obtain results. The main thing is to invert to the degree that brings the amount of relief desired and that can allow total relaxation and enjoyment of the experience.

The amount of time inverting is also quite individualized. Even regular short intervals of 2-5 minutes of inversion time can promote the back pain relief and relaxation. Some people want to invert a bit longer, up to 15 minutes.

People with a history of certain conditions such as high blood pressure, heart problems, stroke or any other medical condition, including pregnancy, that may be affected by increased pressure during inversion should check with their doctor before using an inversion table.

Having an inversion table in the home is highly advisable as its use can not only provide stress relief and relaxation for the whole family, regular use may prevent episodes of back pain in the future. Should back pain occur, particularly low back pain, it can help promote a natural, effective way to obtain relief.
