Logitech x-230 2.1 2-Piece Dual Drive Computer Speakers

Pressure Canner

Manufacturers Description: Crank up the audio on your PC with this 2.1-channel computer speaker system and enjoy clean, crisp, consistent sound from your games, music, and more. The Logitech X-230's high-tech subwoofer adjusts itself dynamically to deliver distortion-free bass, while the two wall-mountable satellite speakers use Logitech's patented FDD2 technology to eliminate the uneven sound response created by conventional dual-driver designs. The result: a clear, uniform sound field without the "hot spots" and inconsistency of other dual-driver satellites.

Features:

-32 watts total power (6 watts x 2, plus 20-watt subwoofer)

-Frequency Directed Dual Driver (FDD2) satellite technology produces a uniform sound field for full, rich sound

-Dynamic, real-time bass equalization maximizes bass response while minimizing distortion

-Ported subwoofer design displaces more air for deeper bass

-Headphone jack enables private listening

-Master volume and subwoofer level controls placed for quick, convenient access

-Satellite speaker stands rotate for easy wall-mounting

Price:

Value Rating: 9.5 / 10 - This computer speaker system sounds better than some speakers that are 0+ with at least 50 watts of power. It has great crisp sound at nearly all volumes and the bass is surprisingly powerful. Be aware that the subwoofer is not magnetically shielded, and should be kept away from your monitor.

Logitech X-530 5.1 5-Piece Computer Speaker System

Manufacturers Description: Plug the Logitech X-530 into your computer, music player, DVD player, or even PlayStation2 or Xbox game console and immerse yourself in clean, crisp, consistent surround sound from your games, movies, and more. The high-tech subwoofer adjusts itself dynamically to deliver distortion-free bass, while the five wall-mountable satellite speakers use Logitech's patented FDD2 technology to eliminate the uneven sound response created by conventional dual-driver designs. The result: a clear, uniform sound field without the "hot spots" and inconsistency of other dual-driver satellites.

Features:

-70 watts total system power (7.4 watts x 4, plus 15.5-watt center speaker and 25-watt subwoofer)

-Frequency Directed Dual Driver (FDD2) satellite technology produces a uniform sound field for full, rich sound

-Matching front and rear satellites deliver balanced surround sound

-Dedicated center channel makes dialogue clear and intelligible.

-Dynamic, real-time bass equalization maximizes bass response while minimizing distortion

-Ported subwoofer design displaces more air for deeper bass

-Headphone jack enables private listening

-Master volume and subwoofer level controls placed for quick, convenient access

-Satellite speaker stands rotate for easy wall mounting

Price:

Value Rating: 9.0 / 10 - A great step up from the X-230. It has the same great sound, with extra bass and a little more all-around power. The extra speakers are great for a surround sound setting. Only downside is that some games are not compatible with the this 5.1 system. Worth the extra for most people.

Logitech X620 6.1 Computer Speakers

Manufacturers Description: More speakers means more sound, more detail, and more intensity. That's what the Logitech X-620 6.1-channel speaker system is all about. Thanks to its 6 satellites, including a dedicated rear center speaker, you can hook it up to your PC or video game console and enjoy your games, music, and movies with sound that truly surrounds you.

Are you looking for powerful bass? Crisp highs and mid-range? The X-620 delivers. Its patented, powerful pressure-driver subwoofer provides twice the bass of conventional designs for smooth, powerful lows, and the satellite speakers provide rich midrange and crisp high-end tones. Even if you don't have a 6.1 sound card, you can still enjoy the benefits of all seven speakers by using the source selector switch.

Got a Sony PlayStation2, Microsoft Xbox, or Nintendo GameCube? Just plug in the X-620 using the convenient video game console adapter and immerse yourself in the explosions, music, and dialogue of your favorite games.

Comes with 6 satellite speakers and a powered 8-inch subwoofer; 70 watts total system power (140 watts peak).

Price:

Value Rating: 9.0 / 10 - Another hit from Logitech. This one is much like more expensive home theater systems. Truely one of the best speaker systems in the growing 6.1 class. An important note: prepare to buy a pricey
Sound Blaster 6.1 Audigy sound card in order to take full advantage of this speaker system.

Logitech Z-5300e 5.1 2-Piece Surround Sound PC and Gaming Speaker System

Manufacturers Description: Demanding gamers require high power, THX performance, and true surround sound. The Logitech Z-5300e delivers on all counts, with a sleek appearance featuring silver speaker accents and removable black cloth grilles. The system includes a patented dual chamber subwoofer that pounds out twice the bass of conventional designs to deliver deep, loud, and powerful bass. The Z-5300e also features polished aluminum phase-plug satellite drivers that project superb high-end and rich mid-range tones for balanced sound, along with a full-featured SoundTouch wired remote that provides convenient controls for quick adjustments. The satellite speakers' rotating pedestals allow for easy installation on the wall or desktop.

Features:

-280 watts system power (35.25 watts x 4, plus 39-watt center and 100-watt subwoofer)

-PlayStation2, Xbox, and GameCube owners can plug in the Z-5300e using a console adapter

-Silver speaker accents and removable black cloth grilles

-Conveniently control volume and power with the wired remote, which also features a headphone jack

-Enjoy twice the bass of conventional designs with patented subwoofer design

-Satellites fit on a shelf or mounted on the wall

-Use Matrix mode and source selector switch to create breathtaking 5.1 surround sound from stereo, 4-channel, or 5.1 sound sources

Price: 0

Value Rating: 8.0 / 10 - This system is almost too much for your average computer user - but it's great for gamers who demand perfection in their sound system. Even though it will work with game consoles, remember that it is a computer speaker system, and works best with a pc.

Canning Food Basics 101

The history of canning food begins back in 1809 when a French confectioner named Nicolas Francois Appert answered the challenge of the French newspaper Le Monde, who had offered a large sum of money to anyone who could invent an inexpensive and effective method of preserving large amounts of food.

Pressure Canner

Since huge armies of men during the Revolutionary War required large supplies of food on a regular basis, preservation was essential. Mr. Appert experimented and observed that when food was cooked inside a jar, it didn't spoil, unless of course, the seal was compromised. He wasn't able to give the scientific reasons behind why the food didn't spoil, but the fact that it worked was enough at the time.

Pressure Canner

Fragile glass containers posed a real challenge during transport, they were replaced with wrought-iron canisters (or as we know them, "cans"). Not only were cans less expensive and quicker to make, they were safer to transport.

The soldiers didn't have can openers, so they used what they had to open the cans, which was primarily their bayonets or a rock. The war actually ended before the canning process and the transport of the canned food could be perfected. In 1814, the factory Mr. Appert had built with the prize money he received from the contest, was burned down by Allied soldiers invading France.

In 1810, a gentleman by the name of Peter Durand patented a process of packaging food in sealed airtight wrought-iron cans by using Appert's methods which were already established. Tinned food was expensive for ordinary people to purchase since it took nearly six hours for the food to cook properly on top of the time it took for each can to be hand-made.

In 1812, the first American canning factory was established in New York City by Thomas Kensett. He utilized an improved version of the wrought-iron cans and preserved vegetables, meats, fruits and oysters.

By 1824, meats and stews which were produced using the method discovered by Mr. Appert, were taken to India by Sir William Edward Parry. Tinned food actually became a status symbol in Europe among middle-class households at that time.

By the 1860's, the canning process took less time, going from six hours to around thirty minutes. Many canning companies began to manufacture in greater quantities after the wars ended in the nineteenth century. They were able to sell their canned food to a wider audience as well.

In response to people in Britain during the Victorian era asking for good-quality food they could store in their pantry, companies such as Nestle and Heinz came on the scene with good-quality tinned food for stores to sell to the working class.

During the First World War, military commanders needed large quantities of inexpensive, yet high-calorie food, to feed their soldiers. The answer was tinned foodstuffs such as corned beef and pork and beans.

After the war, the companies who had supplied the tinned food to the soldiers significantly improved the quality of their goods and thus appealed to the civilian market.

The cans we know today are made from tin-coated steel and are used to transport vegetables, meats, fruits, seafood, and some dairy products.

Canning is a method by which food is preserved by sealing food in air-tight jars, cans or pouches, and then completing the process by heating the containers to a temperature of about 212 degrees Fahrenheit. This high temperature effectively destroys any contaminating microorganisms that could be possible health concerns or that would cause spoilage of the food item.

Those who are just beginning to can foods at home should start by canning high acid foods such as tomatoes or fruits. These foods are safely canned by using the boiling water bath method which sanitizes the food using high temperatures, not high pressure. This is the most basic way to preserve food and since it requires inexpensive equipment, it is a great place to start to learn the art of canning.

For canning with the boiling water bath method, you'll need a large covered water bath canner, a jar lifter, a wide mouth canning funnel, a non-metallic spatula or wooden spoon, a pair of rubber gloves, a clean dish cloth, a heavy dish towel, and of course, canning jars with lids and bands.

Some low acid foods can also be canned using the boiling water bath method since vinegar is used for pickling. Vegetables such as cucumbers, beets, and various beans are all good candidates for pickling. All other low acid foods such as vegetables, meats, dairy, poultry and seafood must be canned using both high temperature and pressure.

Today's pressure canners aren't anything like your grandmother's pressure cooker you may remember. Pressure canners are now lightweight, have thin-walled kettles, and most of them feature turn-on lids. They'll also have a removable jar rack, dial or weighted gauge, gasket, an automatic vent/cover lock, a steam vent (otherwise known as a vent port), and a safety fuse.

Once your tightly sealed, canned jars are cooled, label and date them and then store them in a cool, dry, dark place. Anyone who is willing to follow directions and try something new can master the art of canning.

Vegetables Preservation - The Different Methods

The harvest has been a good one and you now have vegetables in abundance and you certainly don't want to waste all that time and effort by letting the stuff go bad on you. There are many methods for preserving vegetables after harvesting them and the method you choose will depend on the type of vegetable to be preserved and your skills in the kitchen. In this way you can give your family healthy, nutritious meals for a good long while to come.

Pressure Canner

Freezing: is an easy and convenient method of preserving vegetables and it has the added advantage of being the least time consuming of all the methods. It is recommended that you set your freezer at 0 degrees to freeze vegetables. Foods spoil because of microorganisms and enzymes that are present. These enzymes cause the deterioration of food since they promote chemical reactions which include ripening. Freezing helps to stop the enzymes from acting.

Pressure Canner

In order to freeze vegetables properly you need to blanch them immediately after they are harvested. This is one of the best ways to retain nutrients, color, flavor and texture of the vegetables, which can last up to 12 weeks in the freezer. When you blanch the vegetables it prevents the enzymes from continuing to act on them, causing them to lose color and flavor. After blanching, place the vegetables on a baking sheet in a single layer and freeze as quickly as possible - you can try minus 20 degrees. After the vegetables have frozen you can pack them into freezer bags for storing in the freezer. Some vegetables like beetroots need to be fully cooked before freezing and some can be frozen raw.

Canning: is an excellent way to preserve vegetables such as tomatoes, mushrooms and beans that have a high water content. Vegetables that are healthy and disease free should be chosen. Wash them well and then process them in boiling water or a pressure canner. Make sure to use sterilized jars with seal lids that are new. Be very careful not to under process the vegetables especially green beans when using boiling water; the threat of botulism poisoning is very real!

Drying: is also a rather easy process and you don't need any special equipment to get the job done. You can use a dehydrator and if you haven't got one, then use the oven. Choose vegetables that have fully matured, not bruised and diseased ones. There should be good air circulation all through the drying process to prevent the vegetables from spoiling. This process is a long drawn out one so make sure you have lots of time on hand and stock up on patience as well.

Storing: this is by far the easiest method of preserving your harvested vegetables. Root vegetables like onions and squash will last the longest when stored after they have been cured. Fully mature, healthy vegetables should be chosen for storage. Use up any bruised and immature ones at the earliest. You need to clean off the soil and allow the vegetables to dry well before you store them. Don't forget to keep a small stem on your root crops.

Canning Your Own Food to Save Money

You gotta admit this is brilliant; canning and food preservation. People have been doing it for a very long time and it's growing in popularity thanks to the recession. Anything people can do to save money is worth considering and canning food is high up on the list.

Pressure Canner

In our town we even have a community garden where people can tend their own plot of land for free, they just have to keep it weeded and out of other people's areas. The food grown there is being stored in massive amounts, as much as they can get.

Pressure Canner

Canning is big in my family, especially on my husband's side. My mother in law is great at canning and will devote a full day to the event in order to get as much done as she can. During the winter when we get to eat the fruits of her efforts we're all quite grateful. She's very particular about safety and is always sure to use the right kind of cans or jars, the right pressure canner and label everything so we know what it is and when it was done. Don't want to let anything spoil or rot.

Her favorite things to can are meats, fruits and vegetables. We also freeze fresh corn for winter use and that's always a big hit. These are all pretty big jobs to start and you can't just quit in the middle. But the efforts are obvious and immediate. The tools are easy to clean up and now we have food in storage to be eaten later. I love it!

Are Cardiac CT Scans Suitable For Everyone?

How do doctors determine whether their patients have developed heart problems? In the past, invasive angiogram used to be the common and unavoidable procedure doctors will employ. But now, more and more doctors are switching to cardiac computed tomography (CT) scans.

Pressure Canner

It is known that there are at least 16 different types of CT scanners available nowadays in public and private hospitals. But doctors do caution that while these scanners promise a clear picture of the heart through non-invasive technology, they are not suitable for all heart disease patients.

Pressure Canner

According to one cardiologist, "people with heart-related symptoms like chest pain or shortness of breath and who have got abnormal or unclear results from stress test will benefit from these cardiac CT scans."

Cardiac CT uses X-ray imaging to take images of the heart timed to the heartbeats to avoid motion blurring. It can provide information about the extent of blockages by detecting the amount of plaque build-up in the arteries. Compared with invasive angiography, the CT coronary angiogram is highly accurate.

Electrocardiograms (ECGs) and treadmill tests are not very useful for preventing heart attacks, pointed out by another heart specialist. Published studies show that two-thirds of heart attacks occur in patients with 40 to 60 percent narrowing of arteries, yet this is not picked up on treadmill tests or ECG.

He admitted that cardiac CT has done away the need for invasive coronary angiograms in his practice. His many years of experience indicate that once patients see that their scans show blockages, they usually opt to start on medication right away. A trial of more that 2000 stable heart patients completed in 2006 in the United States showed that patients do just as well on aggressive drug therapy alone as they do with angioplasty thrown in.

Medical therapy is not inferior to stenting. Stents are just devices that are put inside blood vessels during angioplasty to keep vessels from narrowing again. Thus, invasive procedures can be prevented.

Nevertheless, risks and certain side effects do arise from using cardiac CT scans.

For example, the contrast dye injected into a patient may cause an allergic reaction, but this is rare. It can also compromise kidney function for people who have kidney problems. Moreover, the exposure to radiation is found to be equivalent to 600 chest X-rays. However, technology is improving and a new dual-source CT scanner which takes X-ray images faster than from a single source does reduce the radiation that a patient is exposed to by 50 to 70 percent.

Walk the Mile With Payless Shoes

Payless is a leading shoe brand company which started out in 1956. The company has its headquarters in Topeka, Kansas. This retail industry not only sells shoes but also deals in accessories and hand bags. Payless shoes are termed as the largest company when it comes to footwear for the entire family in the entire western and northern part of the globe. Payless shoes has its stores in the entire unites states and beyond the country it has stores in the Caribbean countries, Canada and one in Japan as well. They are market leaders when it comes to shoes in the U.S.

Pressure Canner

One in every 10 shoes for adults is a Payless shoe and one in every six shoes for children is another Payless shoe. Critics have noted that the stores of shoes resembled wholesale marts and were not particularly suited to draw in customers who would like a good display first before them, before they like the actual product. The big heads in the company got thinking and came up with innovative design alterations in the company looks. Major changes in the design of the retail outlets were taken up in the year 2005. The outlets were revamped and the brand logo also was changed to make it look more hip, thought the trademark orange was still retained. The new logo came into force on June 27 2006.

Pressure Canner

The company has had its share of ups and downs as well. Payless Shoes Company has been under critic's scanner too many a times due the company's strategy to open up stores in historic buildings and then changing their facade into something completely hip, this completely changes the look of the building and strips it off its character. Like a leading website states, "Payless is a notorious abuser of historic buildings". The company had to witness a sag in its performance in the year 2005 under pressure and competition from another leading company Wal-Mart. The critics termed them as some of the ugliest in the market, this then led to the subsequent revamp of the stores and the company as a whole. The company saw a significant merger with Stride Rite at a price of .50 per share. Its name was then changed into Collective Brands. Payless Shoes are going up and strong and periodically come out with new collections every year.

As the population ages, better wheelchairs, methods of going from one floor to another in private homes, and kitchen utensils for hands crippled with arthritis will be more in demand.
Sports equipment is improved every year.

Pressure Canner

As our standard of living improves we have both more free time and more discretionary money. These factors open up the opportunity for more leisure time products. There is always a market for new games.

Many sports are dangerous. This opens up the opportunity for better safety equipment.
As we search through the channels on satellite TV we find more and more shows featuring do it yourself home improvements. Keep your imagination in high gear anytime your doing a chore around the house. I have a fairly complete workshop, but I was amazed at the new tools in the 2006 Sears tool catalog. A few years ago a box end wrench came onto the market with a geared end that acts like a ratchet.

Now there has been a hinge added to the handle so that the wrench handle does not have to be exactly in line with the bolt head or nut. I am working on an engine that was designed to pack the most H.P. in the smallest possible space and found it almost impossible to get at some fasteners without a hinged gear end wrench that was not even available a few years ago. The end wrench went unchanged for generations until some creative mind added the hinge.
There is a huge market for automotive mechanical and body tools.

Years ago I designed and built automated machinery that, among other things, monitored the current required by the motors and warned the operators when the tools were getting dull. At the time only a large manufacturing company could afford this technology, but with the present state of the art in electronics, it should be practical to have a control that could be preset for a given diameter of a drill bit and the home drill press would turn the proper RPM and have the proper pressure on the bit.

Although woodworking has been around for thousands of years there are still opportunities to improve on woodworking tools.

Look around your kitchen. Why not put a digital temperature readout on the handle of a frying pan? My wife can look at a pot of coffee and tell if it is too strong. Why not an optical scanner to check the darkness and turn off the pot?
There is always a better way to do anything.

I guess you have the idea. As you move through this life keep your creative mind in gear for ways to improve our well being.

Keep notes and dates of all your thoughts. Make sketches. Is It Novel? Is there anything like it on the market?
In order to obtain a patent your idea has to be useful, novel, and not obvious. You must also apply for a patent within one year after the device has been offered on the market or described in a publication. The invention must serve some useful function. You can't patent an idea. You must be able to describe it with words and sketches in such a manner that a person skilled in the technology can build or use it. Before you spend too much time and money on your ideas see if you have any competition.
You think you have a novel idea for a gizmo that will save you one hundred hours of work a year. That should be worth something, but how do you know that it's original?

The best place to start is with a search engine on the internet. Think of every way you can to describe it. Use key words from your descriptions and search places like E-Bay, Yahoo, google, and AltaVista. If you need help with key words, you can take a free course at Cambridge Rindge & Latin School.

By clicking on: www.crlsresearchguide.org/00_Introduction.asp
This is also a great site to learn to do basic research. When searching on E-Bay, search in "All Categories" because some sellers make a poor choice of categories when selling a product. Lets say you just invented the paint brush. Until now there is no such term as "paint brush". What would you call it? Applicator? Applier? Spreader? Coverer? Brush? See what I mean? If you can't find anything like it on the market, then do your own preliminary patent search. You can do this free on the internet. I will cover this more in a later article.
