About Technology

HTC phones offer you almost everything. They have some superb models in their kitty of which HTC Touch Cruise is one of them. This newly launched mobile phone sports almost all those features which one can aspire in a phone. Most of the HTC mobiles are Windows Mobile Smart phones and the Cruise to takes the privilege to be one of them.

HTC Cruise has magical features in it. This touch sensitive screen phone is ladened with multipurpose features. This is can be your communication device, your mini computer for your office work, a full entertainment device. This phone has been launched recently and has the capacity to compete many other high end phones from brands like Samsung, Nokia and Motorola. Let take a quick look at the features of the phone.

HTC Touch Cruise is a quad band 3G phone which supports HSDPA 2100 network for high speed web access, download and other features. This phone has 2.8 inches TFT touchscreen with a technique called 'TouchFLO finger swipe', which is common in all the above said three models for navigation. The Cruise is loaded with handwriting recognition technology and a 4 way wheel navigation system.

In HTC Touch Cruise you have options for card slot, GPRS, EDGE technology for web access, Wi-Fi 802.11b/g, Bluetooth, USB, Operating system of Microsoft Windows Mobile 6.0 Professional, WAP 2.0/xHTML browser an so many other things. The multimedia of the phone is full of entertainment features like 3.15 MP camera with autofocus, 2048x1536 pixels and video along with a secondary VGA videocall camera.

This Cruise model is overall a great device with features like media player to play various types of files like MP3 or AAC/AAC+ or WMA or WA and even AMR-NB files, built-in GPS receiver, TomTom maps, Office Document Viewer, FM radio, album of video and audio tracks, talk time of 7 hours and built in hands free.

Now we see how HTC Touch Cruise phone is able to compete the high profile phones. First its technology of touchscreen is better than other touchscreen phones. It is quad band, has 3G connectivity, Wi-Fi support, big screen, Qualcomm MSM7200, 400 MHz processor, Microsoft Windows Mobile 6.0 Professional operating system and even GPS navigation which are almost common to Nokia N series phones.

Since there is such danger in variable electrical current, uninterruptible power supplies (UPS) have been developed to cover various types and levels of protection for electrical equipment. While these devices are still rather expensive, new developments have recently brought their cost within the reach of smaller companies and even some private residences.

The least expensive, but also least efficient, of the UPS systems is the "off-line" power back-up. These contain a storage battery that can produce the required voltage for a period of up to a half an hour. These units are directly plugged into the standard electrical system where they passively monitor the flow and can detect a power loss and activate within four to twenty-five milliseconds of detection.

The most effective for systems that are critically sensitive to power fluctuations or outages is the double conversion online UPS. These expensive but effective devices are used extensively in industry and computer server environments. One major difference is that in the online system, the batteries are never disengaged from the flow but are continually used and recharged during normal usage. Thus when a spike or fluctuation occurs, there are no relays that have to be engaged. The modulation sensors will maintain a steady electrical supply to the equipment.

There are industry specific devices that function differently from the standard UPS's. The telecommunications industry for example, almost exclusively uses direct current (DC) systems. This low voltage application is easier to use and install as there are fewer safety regulations required in its use. Research into using these systems for protecting computer data centers continues although the power requirements for such systems create additional problems with excessive heat creation in the current units.

There are many more types of power system protection devices for both industrial and hoe appliance applications. With some personal uninterruptible power supply systems providing protection with as little as five hundred watts there is no reason ever to risk you electronic equipment again.

:: Duct/Innerduct materials and colors:

Fiber ducts are usually made from HDPE (high-density polyethylene), PVC or other compound. They are usually in black or gray. Fiber innerduct is usually orange or yellow.

:: Why usually fiber ducts and innerducts are corrugated?

Fiber ducts and innerducts are corrugated to provide the following benefits:

1. Decreasing pulling tensions during installation

2. Very flexible and can be used in installation locations where many turns are involved

3. After installation, corrugated innerduct should be left for a day to allow the innerduct to retreat back into the duct through its corrugated spring action

:: The use of pulling tape

Fiber optic cable pulling tape is preinstalled in fiber duct and innerduct in the factory. This saves significant time during the installation process. Duct and innerduct can also be pre-lubricated in the factory, thus significantly reduces pulling tensions.

:: Never bend over its minimum bend radius

Just like fiber optic cable, fiber duct and innerduct also have a minimum bend radius spec. Never ever should the duct or innerduct be bent tighter than its minimum bend radius.

:: What is supported radius?

The supported radius is the minimum bend radius when the duct is bent around a supporting structure such as in another duct or on a reel.

:: What is unsupported radius?

The unsupported radius is the minimum bend radius when the duct has no supporting structure in the bend.

:: Benefits of using fiber duct

Fiber duct protects the fiber cable and also provides an opportunity for future cable access and expansion. Fiber optic cable can be pulling into existing duct. The duct should usually be oversized to allow future cables be pulled in.

:: Benefits of using fiber innerduct

Fiber innerduct provides protection for the fiber cable from being disturbed by other companies' cable installation operation. It also provides extra protection from the environment. Or fiber innerduct can be used in old duct installation.

:: Things to keep in mind

1. Install end plugs

After the fiber optic cable is installed into a duct or innerduct, end plugs should be installed to provide a water seal. No debris should be able to enter the duct or innerduct, and watertight should always be maintained for the duct or innerduct.

2. Duct and innerduct should be properly sized for future expansion possibility

As always, planning for future expansion is crucial for real successful projects. A maximum of 40% fill ratio is a good practice to follow. The duct size should be increased for long installation lengths with many turns. A larger duct can help to reduce cable-pulling tensions. Standard duct sizes vary from 3 to 8 inch ID and innerduct sizes vary from 0.75 to 2 inch.

:: The benefit of using duct lubricant

Duct lubricant can significantly reduce the cable's coefficient of friction, thus lessening the pulling tension during cable pulling process. This is especially important in long cable duct pulls and pulls with many turns.

Duct lubricant spillage should be cleaned up as soon as possible to prevent accident since it is very slippery. Manufactures' recommended procedure for cleaning lubricant provides good instruction on how to do the cleaning.

People often are used to upgrade their office and home PCs. A few people upgrade their PCs by exchanging the old one for the new one. A few people prefer just upgrading the outdated parts. One good example is the monitor.

The two different monitor technologies are CRTs and the LCDs. CRTs use the cathode ray tubes and are so hazardous to the human health. They cause headaches due to a high refresh rate. These operate at very high voltages and can persist long even after the power is turned off. It consumes more electricity than an LCD screen.

It even emits a small amount of X-rays which can cause severe side effects when exposed continuously. The only advantage the CRT has over the LCD is the resolution and the price.

But if you can buy a refurbished LCD, It can beat the cost of a CRT monitor. The LCDs consume less electricity and are less hazardous to our eyes and do not emit X-rays. The image is very sharp, thanks to the liquid crystal display technology.

LCD monitors contains two sheets of polarizing element filled with liquid crystal solution in between. When current is passed through the liquid solution, it causes the crystals to align so that light can't pass between them. Each crystal acts as shutter letting light to pass through them and blocking the light.

When human health is given the priority LCDs have the upper end and when price and the resolution is given importance the CRTs emerge as the victors. Its all up to you to pick the one you need.

Toshiba and Sony have a lot riding on their high def DVD technology, and that's why the two have been in such a fierce battle to dominate the market for this technology. Both of these two electronics giants have their own high def DVD formats. Both of these formats can be used to store and retrieve an entire full length HDTV movie on a normal sized optical disc. And neither of the two formats can be played on the other's players.

Generally, it's agreed that only one of the two high def DVD formats can survive this format war, but there are two other outcomes that aren't discussed as often. The first outcome, one that's fairly likely actually, is that both formats will survive the war and will both exist side by side for the lifetime of the technology. The other outcome, which is also conceivable, is that both of these formats will be defeated by some other technology.

First, the scenario where both formats exist side by side. This would come about because of third party technology that could make the distinction between the two formats irrelevant. There are already technologies like this in existence. One is the dual format disc on which a movie title, in both formats, is encoded onto a single disc. As the standard way to release discs, people would be able to buy high def discs without any thought as to which type of player they own. Another solution comes in the form of a dual format player. These devices are also already in existence, but are presently so expensive that it makes more sense to buy a player for each of the two formats- it would be cheaper.

There are lots of new technologies on the horizon that could also bring about the demise of both formats. One of the more likely ones is high capacity hard drive technology. With hard drives larger than a terabyte already available, and improved video compression technology, it may soon be possible to buy portable hard drives preloaded with an abundance of movies. These movies could be unlocked for viewing one by one in exchange for paying a small fee, which would reduce the upfront cost while allowing consumers to avoid the inconvenience of downloading the movies off of the Internet. Of course, these hard drives could have space reserved for the storage of recently released movies that could be downloaded off of the Internet as well.

Another interesting possibility is that HDTV could soon be obsolete, and therefore HDTV DVD's would become obsolete as well. One of the technologies that could replace HDTV is 3D TV. Of course, any kind of 3D TV of the future probably will have HDTV resolutions, but the extra amount of data required to render a three dimensional image would exceed the storage capabilities of even high def DVD's. Perhaps HDTV DVD technology could still be used for short format 3D HDTV, but it would hardly be sufficient for full length titles in the new format.

With these and other new technologies on the horizon, putting a lot of resources into high def DVD technology is a risky proposition indeed.
