What keeps IPOD apart from others?

People have intense love affairs with their machines, like some men are known to be enthusiastic about their cars, and some women are known for some household appliances. But the iPod seems to top them all and seems to pull strings at the heart with such consistency that some people, irrespective of age, sex, color, and creed, make the mp3 player device an extension of themselves, an extension of their personalities, and an extension of their lifestyles!

The marvel of the 21st century, the iPod, never had it so good. Psychologists are of the opinion that because primarily an iPod delivers music and the human mind is naturally attuned to music, therefore it is an instant hit. But there are other mp3 player devices around, then what makes this device so unique? Market analysts say that the small size of the iPod, its capacity to store thousands of songs, and its ability to use the computer as an alter ego, has contributed to its tremendous sale.

However, market survey agencies pronounce that the popularity of the iPod is mainly due to the strong identification between songs and emotions. When people hear a particular song, they identify it with some emotion, some event of their lives, and they relive those moments of the past. This makes them feel happy, which in turn justifies the amount of money they have spent on purchasing their iPods.

People have gone on record to say things like when they hear romantic songs they are reminded of their ex-girlfriends or pleasant moments. When they hear songs like Bette Midler`s `Wind Beneath My Wings`, they are reminded of their husbands. Stock exchange brokers and traders identify their job and lives with the Frank Sinatra song, `My Way`. Similarly, Linda Ronstadt`s `When Will I Be Loved`, and Peter Frampton`s `I`m in You`, reminds one of the high school dances. This association with emotions makes the iPod a must-have consumer product.

Some iPod users have something more than an intense affair with their mp3 player music devices. Something more like an obsession. It is an on going love story. Sociologists claim that the iPod makes some individual a good societal being, as their frustrations are released by simply listening to their favorite songs. Dramatists affirm that emotional catharsis is superbly performed by iPods. Some medical experts state that mp3 player devices may even eliminate depression and elevate one`s mood.

As music tends to be very personal, it becomes very emotional. So when you listen to the songs stored in your mp3 player device, you tend to get emotional and take a walk down memory lane. Thus, iPod becomes a small, compact memory bank, which you can carry around with you, wherever you go.

The ability of the iPod to rewind your life backwards and hear it, being enacted in lovable musical melodies is perhaps the greatest selling point of this machine. No wonder then that more than 22 million iPods have been sold in a few years only! No wonder then you see people with their music players down the streets, at Harris Teeter while shopping for Cocoa Puffs, while doing stretch ups at Gold`s Gym, or sipping high quality afternoon tea at the Ritz`s. The iPods have become absolutely indispensable, completely irreplaceable, and simply irresistible!

With the iPods now coming with multimedia capabilities, they have become small, personal cinema houses, compact media players to view home videos, or even to show some commercial multimedia applications. Thus, with passing time, the popularity of the device is increasing as it enters new vistas of commerce, arts, and sciences. The iPod has indeed become multifunctional and multifaceted, and has aptly adapted to the needs of changing times. This adaptability is the prime reason why this music player sells so much!

How Can You Get Maximum From Your Portable Generator

Your portable generator is your only refuge in the case of a power-cut, when there is a great need to keep thing moving and working. To be used as a temporary source of power for emergency after calamity – like, hurricane or tornado - portable generator is a popular option. In such cases, if there is a need for rescue and retrieval, especially during the night, the portable generator can keep machines and lights going for the purpose.

A matter of concern when it comes to a portable generator is that it can be a health hazard to people, if not used properly, more details are located at Hondageneratorstore website. Hence, it is the responsibility of the users to use portable generators in the right way.

Chiefly, there are four main hazards that portable generators can impose:

i) Release of carbon monoxide from the generator’s exhaust

ii) Fires due to improper refueling

iii) Electrocution or shocks due to wrong connections

iv) Loud noise and vibration.

Carbon monoxide is a toxic gas. Its undetectable nature makes it all the more dangerous, as it can lead to death due to suffocation. It is unlike other gases – being colorless and odorless – that it why it is impossible to sense.

Keep your portable generator in places where there is proper ventilation, so as to avoid poisoning due to carbon monoxide. Closed spaces - like a room, basement, or garage – are a complete ‘rule out’, when it comes to placement of portable generator also check out all safety precautions at hondageneratorstore. So are places like windows, doors, or any kind of openings in the house.

If you run the generator indoors, keep in mind that open windows or doors are no guarantee or safety against carbon monoxide build up. In fact, the harmful effects of carbon monoxide can also enter open doors or windows, even if the generator is run outdoors. If anyone experiences symptoms like giddiness, nausea, headache and fatigue, take the person to an open area where he can get fresh air.

Generators, like car engines, get hot when their engines run for a long time, get more details at hondageneratorstore But unlike car engines, generators remain hot for a long period of time, making it impossible for you to refuel them, while running or immediately after they are shut down. The generator needs to be cooled down for a while. Once the temperature is safely low, refueling can be done. Fire can also occur, even before your intention to start refueling it, particularly if your gasoline containers are placed near or beside the generator.

Generators should be considered as ordinary power sources. Since generators do not have safety devices - like circuit breakers and transformers - they can cause harm, more so in case you happen to get electrocuted. Keep every connection clear and clean, to ensure the safety of everyone around. Avoid unnecessary and unsafe connections, as well as tangling ones.

Keep the generator dry, as under no condition should you let it work in the rain. In case it starts raining, use a canopy to cover the generator. Don’t ever attempt to connect any devices when you are barefooted. And under no circumstances should you connect wet electric devices to the generator.

Board-by-Board Optimization

Just as each board type enjoys its own thermal profile in your surface mount oven, each board type also enjoys its own board-wave parameters in your wave machine

The optimal dwell time for that board was found to be 3.6 seconds, in contrast to 2.8 seconds for the first board. As you can see, the “dwell time profiles” of the two boards are different. This process resulted in dramatically lower defect rates for the second board studied (which had also been previously run at 1.0 seconds), although never quite as low as the new baseline which was attained for the first board. This strongly indicates the presence of sources of defects unrelated to dwell time, for example non-optimal immersion depth or design problems.

Immersion Depth

Changing your immersion depth changes your contact length and dwell time. This makes the direct and accurate measurement of immersion depth critical. Your pump speed produces a wave height (although this can diminish as your solder pot empties of solder), but the actual immersion depth of your boards depends on several factors, including solder pot height, how they sit in the fingers, if your fingers are bent, broken or crooked, the angle of your conveyor and whether or not pallets are used.

Yet controlling your immersion depth - measuring it and keeping it consistent - is only one piece of the puzzle. Another is: At which immersion depth is your board quality optimized? This point is illustrated by figure 4. See that the defect rate of the board represented by the blue bars is optimized over a different range (48 mil, or even 36 to 60 mil) than the board represented by the yellow bars (at 24 to 36 mil). So, different board types benefit most from different immersion depths.

Quantifying Cost Benefits

Prior to this study, yield loss was tracked on a monthly basis as a measure of the cost of production failures. Production volume for the board studied was 11,000 per month.

1.) With the implementation of optimal dwell time procedures using the described device, yield loss went from 3.0% (330 boards) to 1.6% (176 boards) in the first month of daily use.

2.) This meant a reduction in yield loss of 154 boards per month. For a 30 day month, this means 5.13 boards per day.

3.) At 0 for the cost of each board, cost reduction based on improved yield loss alone was ,200 per month, which annualizes to 4,400.

4.) That means that the return on investment on the device used in the study was less than five days.

Conclusion: A seemingly small daily improvement in wave solder quality meant fast, very large, measurable monthly and annual cost savings. These figures do not even account for the valuable savings from benefits like reduced rework and field failures, less downtime and increased throughput, each of which in its own right can be more valuable than the rapid savings on yield loss.
