Heart Rate Monitor is What You Should Consider
Posted by Parkzone Corsair in computer on August 21st, 2010
Definitely you are eager to know how you are burning your calories for your weight loss concern. Ever since I was little; I have always wondered why all athletes kept looking at their watches. I thought that they were timing themselves to see how long they can take to run the competition distance. Little did I know that they were testing their super hearts to see if they would compete with their preferred finish time? To them it’s not how long they took but how many seconds went below or above the set time. Heart beat testing. ‘If it’s not fast enough then I need to run faster!’ These are the Wonders of a heart rate monitor.
This explains what takes place behind the scenes in a working out gym. Time is the factor. The heart is doing its thing. How far can it go before begging for a rest? Little by little the heart leans to put up with the kind of exercise you are enthusiastic about in order to reach your goal. It could be you are just keeping fit. Actually your body is ok and healthy. Could be you are trying to loose weight, yours is too disgusting. Or may be you are the kind who believes that you were born to work out. It’s your fun. Whichever the case you need a Heart Rate Monitor. Test your heart.
We may worry for our hearts that may be we are working out so hard but sincerely speaking the harder the exercise the more your heart beats that is just what you are looking for. With time your heart will get used to it and you will start enjoying it and always becoming eager to be in your favorite gym. You need the help of a heart rate monitor though. You need to know how hard your heart is working and in order to achieve our goals without necessarily overworking your heart. That is why you need your heart rate monitor.
For me as long as I don’t exceed the proper intensity level of at least giving my heart like 20 to 25 minutes of rest for effective aerobic function per work out I always worry less about working out too hard. I like it that way. One thing am careful about is to go against what my heart rate monitor is revealing to me about the working of my heart. If it tells me am overworking it then. The upper limit speed always being 85% it is important that you check out on it. I always obey my heart rate monitor ‘hey’slow down’ or ‘you are too slow’.
The most common heart rate monitors are easy to use attached to your wrist with a clear display of the speed, mostly digitalized. Also depending on the model, the heart rate monitors will give you other very important information necessary for your progressive work out. Before purchasing your Heart Rate monitor, know your needs, like for your weight loss you may need a heart rate monitor that can monitor your calories burning. And for the fast runners you may want a stop watch attached and many other considerations you need to put in mind before you go back to your pocket. The choice is yours but you need to work out anyway and not just work out but beneficial work out. So go for the Hear Rate Monitor for your advantage.

Should I Repair or Replace My LCD Monitor?
Posted by Parkzone Corsair in computer on August 14th, 2010
REPAIR USUALLY MAKES SENSE & SAVES DOLLARS.
It is generally better to repair than to replace for several reasons. Monitors, (or terminal displays), should have a life span of ten to fifteen years. LCD screens should last even longer. Failure of just one tiny component can render a monitor useless. Until the tube or main transformer fails, repair is the logical, cost-effective choice.
All monitors and terminals contain potentially dangerous heavy metals, so repairing also makes your company environmentally friendly as you delay adding to the amount of computer waste in our landfills. And most important, repairing is a cost saving over the purchase of new electronic equipment.
The most common failing of an LCD monitor is dimming of the backlight after substantial use. However, for about $20.00, the backlight can be replaced and the monitor restored to its former self.
Nowadays, there are highly competent, anti-reflection polarizer films available in the market. This polarizer film when applied to the LCD screen increases display contrast as well as readability. Images become sharper and clearer; the screen provides deeper colors; it allows for a wider viewing angle in bright settings; and protects LCD panels from scratches and fingerprints.
The flat panel in the LCD television makeup is the most expensive item to replace. In fact in some cases, it could exceed the cost of the total unit. Split or broken LCD panels obviously need replacement. Another sigh of a flawed panel are lines running the length of the panel. Still, three quarters of such panels can be repaired.
There are many LCD repair courses & books available on line today, which makes it even easier & more cost effective to repair, rather than replace your monitor. The courses will walk you through a step by step guide on how to fix your problems. They are easy to follow but leave nothing out. Some of these courses & books will cost you a little money on the initial investment, but in the long run, you could save thousands!
Just so as not to mislead you, there will be times when you will need to replace your LCD monitor. With a little on line research or the advice of a technician, you will be able to tell what the best option for your specific case is.
Good luck!

Should Businesses Buy a Projector or an LCD Display?
Posted by Parkzone Corsair in computer on August 13th, 2010
With the price of large (>32â) LCD displays decreasing rapidly and new functionalities being added to LCD displays, does it still make sense for businesses to buy a projector vs. an LCD display?
Some of the variables to consider when evaluating this question are product quality, price, picture quality, screen size and other such considerations. We discuss these and other factors from a typical business organization perspective. Read other articles and make your informed judgement.
Product Life: LCD TVs or displays typically have a backlight life of 30,000 to 60,000 hours (ie, if you have the display on for ~6 hours every day, the backlight will last for 16 years). Even then the backlight can be replaced in most LCD displays. A projector bulb typically has a life of 2,000 hours.
Price Considerations: A basic projector can be found for INR 25,000. However, if the projector is going to be used for video conferencing or board room presentation, a high resolution, good contrast ratio and saturated colour projector would be required. The cost of such a projector is close to INR 1 lakh. Thereafter, you need to factor in the prices of projector bulb and projection screens. A typical projector bulb needs to be replaced almost every year or two with bulbs costing Rs 20,000+ per bulb. We have added these costs over a five-year period to compare a projector vs. an LCD (see chart below). With 46â LCD TV or display costing around Rs 135,000 â Rs 150,000 and dropping, price becomes less of an issue when considering whether to buy a Projector or LCD display
Figure: Total Cost of Ownership Comparison for Projector vs. LCD Display
Basic Device capital cost for projector is INR 70,000 and that of an LCD display is INR 150,000, Projector Screen Capital Cost (Wall Mount Screens INR 5-15K) is INR 10,000, Consumable cost of the projector is 20,000 x 3 = INR 60,000, Consumable life of a projector is 2,000hrs and that of an LCD display is 60,000hrs and the Cost of Ownership of a projector is Rs.140, 000/- and Rs.150, 000/- for an LCD display.
Assume: 5years of usage @ 5hrs a day ~ 6600hrs of use. This translates to 4 lamps in 5 years requiring the customer to buy 3 lamps in addition to 1 supplied with machine.
What is clear from the above figure is that a Full High Definition 46â LCD Display is, at best, only marginally costlier than a XGA Projector of ~2500AL. Additional costs of low screen installation costs and lower device loss costs are purely additional.
Picture Quality: Projectors such as a DLP or LCD projector use glass panels to combine red, green and blue colours to create the image. When sitting close to screen, the viewer can see the different colours at the borders of an image, aptly described as the rainbow effect. The rainbow effect takes away from the image quality and can give headaches. High-end projectors have been able to reduce the rainbow effect, however the problem still remains and these high-end projectors cost more. LCD TV or LCD displays do not have rainbow effect issues and the quality of the picture is good at close range.
Rather, projectors cannot compare with the picture quality for an LCD display. The vividness of the colours, the contrast ratio, the colour saturation and image sharpness are much better for an LCD display than a projector. When viewing a projector image, especially in ambient light, the viewer has to dim the lights or close the curtains unless the business has purchased an even more costly higher lumen projector. Not true with LCD displays, as the brightness and colour quality are much better.
Viewing angles used to be an issue with LCD displays but this issue is no longer true. Most LCD displays can be viewed from up to 176 degrees.
Dead or Stuck Pixels: Projectors can suffer from dead pixels and LCD displays can suffer from stuck pixels. Both dead pixels and stuck pixels result in white spots in the projected image. However, the manufacturers of both technologies have worked hard to minimize such issues and in most cases they provide warranty against such issues.
Screen Size: A common thought is that screen size is not an issue for most projectors as the thinking is that the projector image can be made larger by moving the projector away from the screen. This is not true as the image quality deteriorates as the image becomes larger. With projectors, most buyers opt for maximum optimized projector image sizes from 76-inches to 120-inches and the actual working normal projection image used is much smaller. Today, if businesses need a large LCD display in the maximum projector image size, a wide variety of competitive LCD displays can be found in this range.
Portability: Projectors are easy to carry and move around. For a business this could be a value-add or a drawback. LCD displays are durable and can be moved however they are not as light as projectors.
Power Consumption: Projector power consumption varies more from unit to unit, with brighter conference projectors requiring more power than smaller portable projectors. It is hard to compare the two technologies on this performance parameter.
Connectivity: Most LCD displays have more number and different types of ports than projectors. As a result more types of devices can be connected to an LCD display than a projector.
Other Value-Add Features: New features are appearing in LCD displays that could be quite valuable for businesses. For example, touch screen features on LCD displays allow for LCD displays to be used as digital whiteboards where the data written on the display can easily get captured electronically in a text document.
