How do we save the planet? One of the ways we could try would be to decrease emissions. This may sound trite and simplistic, but it could certainly work. Some observers say that if you want to see how much your household appliances use in terms of energy consumption, then ask your cat to sit near it. The nearer it sits then the more likely it is to be energy inefficient and therefore warmer.

Cats love heat and energy inefficient devices lose heat at a rate of knots. It make take a more scientific and logical approach to this exercise and by a meter which can tell you just exactly how much energy your appliance is using. By doing this you can at least try and eliminate the power consumption of some of the more hungrier appliances and therefore save not only electricity costs and other fuel goals, but also the planet.

Take, for example, low energy output light bulbs. These consume about 20% of the power of normal bulbs and weighs only 80% of the energy compared to the 95% of conventional bulbs. Scientific advances are continuing a pace and is now possible, in properly adapted homes, to buy devices which can automatically change the heating and lighting that was depending on the prevailing weather. How about having devices turn themselves off or at least go into low power consumption mode when, for instance, lights are turned off.

When someone leaves the room, then appliances could possibly communicate with each other and detect that the user is no longer around and therefore the appliance is no longer needed.

Notebooks have emerged as a bare essential for the business executives who carry their work along with themselves. Notebooks which are also known as laptops can facilitate the work process thereby saving substantial and valuable time. In short, it is used as tool of time management.

Owning a notebook is a dream of many, but since it is very expensive nobody buys it unless it is indispensable to them. However, some people having shoe-string budget look for a good notebook. They are the ones who need detailed and comprehensive information on notebooks and laptops before they settle for one.

Basically, buying a notebook or laptop largely depends upon the personal choice, specific requirement and social status of a person. Besides, different manufacturers are introducing notebooks of different look with a wide-range of features. However, some notebooks are launched in the market to cater to a particular segment of buyers keeping in mind of their specific needs. Accordingly, these laptops differ in flavor, class and quality.

Let`s take a look at the various types of notebooks that are available in the market today. Keeping various factors in consideration the notebooks can be broadly divided into four major categories, such as:

Budget laptops - Typically, these laptops cost around US$ 1000 to $ 1200.

Mid-range laptops - Notebooks of this category can be found with a price-tag of about US$1200 to $1600.

Ultra-portable laptops - These light-weight laptops ranges from US$1600 to $2200.

Laptops for the people with a class apart. With all the standard and advanced features in these notebooks, they cost above US$2200.

Performance test of laptops:

Notebooks can be tested on the basis of certain benchmarks such as Multimedia content creation 2003 and business Winston 2002. These tests determine the performance ability of different notebooks with regard to regular productivity applications and multimedia content application.

Similarly, 3D Mark05 and 3D Mark06 are used as standards to measure the gaming and graphic potential of different notebooks.

Likewise, PC Mark05 is taken as a yardstick to test various components of notebooks such as hard-disk general usage, multithreading, web-page rendering, file decryption and 3D pixel shader.

Moreover, the battery back-up and wireless connectivity can be tested using Battery Mark02 and QCheck as the benchmark.

Finally, Vista Compatibility Check can be undertaken to test if the notebooks have Vista-readiness. Under this test, the performance of the laptops is assessed on the basis of Vista drivers and Vista upgradeability.

features:

When it comes to features, the list seems endless. Some expensive notebooks have the most advanced features such as built-in webcams, fingerprint readers, TPM and so on. So far as the features go, they can be divided into five different categories, such as:

Physical - Screen size and weight of the notebook

Connectivity - Bluetooth version 1/2, infrared, MMC reader, S-video, DVI port, firewire. The number and type of USB ports and pcmcia slots.

Components - Type of optical drives, whether the notebook has a DVD combo, a CD-RW or a multi-recorder DVD-RW. The hard-drive capacity and any additional component such as wireless optical mouse or an MMC adapter.

Software - Software have always been an essential part of the package. These include recovery CDs, driver CDs, OSes, etc.

Protection - All types of protection available in a notebook, be it a finger-print reader, BIOS level HDD protection, touch-pad lock, TPM, or even rescue option available at the time of boot up.

Pricing and Warranty:

All notebooks ranging from $1200 to $4500 offer warranty of 1 year and some laptops have the option of additional extendable warranty.

So, the above discussed comprehensive analysis and performance tests will definitely help those who are planning to buy a laptop.

If I asked students who take my golf lessons how critical good rhythm is to a good swing, most would agree that it's important, but not the most important factor. Many weekend golfers would probably agree with this assessment. But a new device developed by a professor at Yale reveals that good rhythm is more important to chopping strokes off your golf handicap than many think.

bob Grober, a professor of applied physics at Yale University-and a one-handicapper- recently invented a device for translating the rhythm of a swing into sound. Here's how it works: A small wireless transmitter inserted into the butt end of a club detects the club's movement. The signal produced is transmitted to an iPod-sized unit attached to the player's waist. The auditory signal is relayed to a set of lightweight headphones and the sound manifests itself as a pleasing organ-like tone when the player swings.

If your clubhead is decelerating through impact, your transition from backswing to downswing is too abrupt, or your mechanics are way out of sync, Grober's device tells you through sound. The faster the club travels, the louder the volume and the pitch. The idea is to make the loudest sound at impact, not before. Grober's device also registers how fast the club is moving on the downswing, and gives you a start-to-finish speed profile. It's a handy tool for serious golfers.

Swing Profiles

Using this device, Grober was able to isolate three distinct speed profiles among golfers. Golfers with high golf handicaps (20+) are cursed with lousy rhythm. They're like dancers who have two left feet, always tripping over themselves. Golfers with golf handicaps from 20 to 5-intermediate golfers- tend to complete their swings too quickly. The loudest sound comes just before impact.

Then there are golfers with golf handicaps below 5. Let's call them tour players. They also tend to rush their swings but to a much lesser degree than intermediate golfers. Like the intermediate golfers, these players create the loudest sounds just before impact, but they do it much less often than with the intermediate golfers. More often than not, their loudest sound comes right at impact, which explains why they hit the ball so well.

improving Rhythm

The best swing according to Grober contains a brief period when the club is hardly moving at all while the lower body begins to clear out. Unfortunately, weekend golfers tend to hurry the transition from backswing to downswing. That disrupts the player's rhythm and throws off his or her swing at impact. So the loudest sound comes just before, not at, impact.

The professor's device doesn't tell us anything new about swinging a golf club. It just reaffirms what we've suspected all along regarding the rhythm of the swing: That it's one of the keys to hitting a ball well, if not the key. So how can you take advantage of this information?

first, relax your hands at address. If they're tense or tight, the rest of your body will be tense. Whenever Johnny Bench, the great baseball player, wanted to hit the ball for distance, the first thing he did was lighten up on his grip. That relaxed his hands and his arms and body.

Second, work on swinging to a beat. Pace yourself when you practice. Think of your swing as a one-two motion. one is your backswing. two is your downswing. You can even say something like "one-two" during the swing. "Back and through," "low and slow," or "turn and turn" also work.

Third, practice swinging with your eyes closed. By swinging with your eyes closed, you can feel the weight of the club and sense its speed gradually accelerating from the top of your swing all the way through to a controlled finish. Once you've mastered that, re-create the swing on the course. If successful, you'll see your consistency improve and your bad shots diminish.

Most golf instruction sessions focus on the mechanics of the swing, not the "intangibles," like rhythm and tempo. But as professor Grober's device reveals through analysis of sound, the intangibles are just important as good mechanics, if not more important. If you want to become more consistent and cut your golf handicap down to size, focus on improving both the mechanics and the intangibles.
