In these recent years, with 3G and 3.5G being accepted as a common and popular mobile network, HSPA (High-Speed Packet Access) becomes very crucial for road warriors, as they are much faster than GPRS network and easy to use.
A person will need a 3G or 3.5G-enabled devices to use this high-speed network (of course, this service is dependent on the Telecommunication Company of the country). It can be in-built in the devices already or it can be in an external unit.
This review is based on HuaWei's USB Modem E170. HuaWei Technologies Co., Ltd has been aggressively promoting their USB Modems.
HuaWei's latest USB stick modem is much smaller than its predecessor (E220). Technically, this USB stick modem is actually a modem, an USB flash, a virtual CD-ROM drive.
In this review, I will be using the modem from Singapore Telecommunication operator, Starhub.
The package from Starhub comes in only white colour with a Starhub logo. It is packaged into a DVD size cover with the modem itself and an extended cable. The major difference between E220 (the predecessor) and this E170 is that E170 itself has already a USB connection point. In normal operation, you will not need to use the extended cable. In the operation manual, it states that this cable may be used to enhance the signal. You will need to purchase the SIM Card separately for this modem. Or you can use your existing SIM Card on it. Starhub bundled this package with an unlimited Data SIM Card that is easy to install onto the device.
The modem is very light and the finishing is of high quality. The size is slightly bigger than a convention thumb drive. The Dimensions is 80.5mm long by 24.1 mm on the width and 11.8 mm thick. It is glossy white in color and extremely well made. The USB connection is hidden with a cover that is quite sturdy. The cover comes with a silver hinge for you to hang this device around. Near to the USB connection port is the SIM Card holder. It is carefully hidden and flushed with the overall design. I wouldn't be too sure about that as the device may drop off if it is being pulled (and you are left with a cover only).
As mentioned previously, this modem is a virtual CD-ROM drive. Reason being that the software is flashed into it and it is detected as a CD-ROM drive when plugged in. A Dell laptop was used for this connection check. It took about 5 minutes to setup the modem automatically. You will be prompt for the first time to install the software into the computer. It is a compulsory step. After the installation, the Starhub connection panel will show up and you just need to click on the connect icon. Starhub connection is based on HSDPA/HSUPA/UMTS/EDGE/GPRS/GSM.
It takes a minute for it to connect (the modem that I have is without password. Therefore, it is automatically connected when I push the connect icon).
The main panel will show connected once it is done and on the bottom right hand corner of your computer, you can see the Starhub modem logo.
On the main panel itself, you can switch to the statistics page to see the upload and download speed with a nice graph. There is also the text and phone book page that I did not explore. Basically, according to Starhub, the SIM Card is a data card that could not be used for calling. However, basic text messaging is possible. As for the phone book, it is the contacts storage of the SIM card. For this bundle, there are 500 contact slots.
Ideally, the download speed for this modem using the Starhub service should be 7.2Mbps. However, the actual performance showed otherwise. This could be due to the signal strength and download sharing factors.
A few tests were done on a website by clicking a link on it to a heavily pictured page and also by refreshing this same page. Both results were satisfactory as it can be loaded within a minute.
The connection is stable. In fact, this unit was tested with Skype and webcam. It has a little lag but this may be due to the other party wireless connection. Therefore, this is not conclusive.
This little device is best for Road Warriors to download emails and surf the Internet. As the form factor is small, it can be easily carried around. With an unlimited Data plan, this unit can be connected to the Internet all day without worrying about the bills.
The HSDPA Downlink is 7.2Mbps & HSUPA Uplink 2Mbps, it is still not the fastest as compared to a LAN network. It is not intended for gaming and if you have many heavy files to upload, you may feel the lagging.
If you intend to use it overseas, please check with your Telecommunication operator on the overseas data rate. It may cause a huge dent in your wallet.
Overall, this device serves the basic purpose of connection on the move. With is small form factor, it can be carried anywhere. The connection speed is very dependent on the telecommunication operator. With testing on the previous model (E220) at a 1.8Mbps to 3.6Mbps, some connection heavy task could be quite taxing. You should seriously consider the minimum standard of 7.2Mbps downlink if you wish to use it frequently. It is a Must-Have item for Road Warriors at this moment.
Characteristics of a cell phone with PDA capabilities include connectivity with numerous PDA accessories especially designed for such as a smartphone. With this fact in mind, go ahead with your plans to find handheld accessories that might be those you need for improving your communications in the future.
Most people buy a PDA cell phone for making phone calls and to hold some personal information. These features are the entry point most of the times. However, as soon as you are getting familiar with your smartphone, a number of features can be missed in the model of your preference or the need of a special accessory, including those providing connectivity, such as the Bluetooth technology.
If you want to make sure that a smarthphone gives you the best, go for one of the three top PDA cell phones available on the market, from which Motorola PDA cell phone is among the favorites, enabled for the next hook-up.
Motorola's PDA accessories make it possible for almost anything in mobile technology, being also a leader in handheld accessories and the most wanted smartphone when it comes to business productivity
Dell PDA cell phone is another of the top choices in mobile technology, with the background of a desktop computer system that makes it possible for a better understanding of the final user’s needs, and the importance of keeping connectivity between smartphones and other devices.
Dell's PDA accessories include battery replacements and travelers kits, making easier the transition from traditional handheld accessories to phone hook up technology.
Nextel PDA cell phone is closely competing with i-Mate on the top chart of PDA-enable smarthphones, being both one of the most affordable options to access the Internet as well. Like most PDA devices, Nextel and i-Mate offer a number of PDA accessories, along with the functions that everyone can expect for a portable organizer.
Whatever brand is your choice, make sure that your PDA cell phone has full WiFi compatibility and enough handheld accessories so it becomes an investment instead of just an expense. As technology evolves, more and more features may be needed so go for the smartphone with the most options and you will never regret your purchase.
In addition, of course, if you want to go with the majority of people, try Palm. Although with phone capabilities, Palm One and Palm Treo are basically considered PDA devices that guarantee you are getting the full range of functionality and connectivity with other mobile and desktop devices.

The cathode ray tube produces pictures by firing electrons at the screen of the TV where they're converted into photon of various colors, which in turn produce the pixels that the pictures that we see are composed of. This type of technology is still available, but has largely fallen out of favor in recent years because it's difficult to manufacture in the 16:9 aspect ratio that's now preferred for devices like HDTV sets (though there are HDTV sets that take advantage of cathode ray tube technology), because cathode ray tubes take up a lot of space, and because they consume significantly more power than newer technologies. While it would be nice to think that we're above such things, it's worth pointing out that cathode ray tube TV's have also fallen out of favor because flat panel TV displays are much more stylish.
The flat panel displays that are so much in favor these days actually come in two varieties with the possibility of a third variety on the horizon. For a long time the leading type of flat panel TV display on the market was the Plasma screen. Plasma screens are composed of tiny pockets of gas that glow when excited by an electrical current. Each pocket of gas represents one pixel and the result of having them combine to form a picture is a screen capable of rich colors, deep blacks, and an ability to display quick movement.
Another advantage of the Plasma screen display is that there's now physical limit on the size of a Plasma screen TV (although there are economic limits). Plasma screens do have a decent number of disadvantages though. Plasma screens consume a lot of energy, they fade in brightness over time, they don't look that good at higher light levels, and if you try to use one at an altitude in excess of six thousand feet it will make an annoying buzzing sound.
The most popular type of flat panel TV these days is the LCD display. LCD displays have longer theoretical life spans than Plasma screens. They also consume less energy, function well at any elevation, and look better in a wider variety of light levels. LCD screens work well with computers and are becoming increasingly affordable. They do have some problems with displaying deep blacks and have some trouble with blurring while displaying fast moving objects. Both of these issues are less of a problem on newer models.
The flat panel TV technology that's in the pipeline is called Laser TV. This type of technology uses actual lasers to produce images on the screen. It promises to get around some of the problems of the LCD technology while consuming less energy than the Plasm screen. It should also be lighter and more durable than earlier types of screens because of greater use of plastic in the design.
Clearly, no matter what kind of TV you end up with, there are some interesting options out there.
Car is now part of daily life and culture, so it's difficult to imagine getting from one place to another without it, irrespective of distance. The future of the car, as we know, is doomed because of emission of large chunk of our greenhouse emissions, and fossil fuels set to become more costly before eventually running out. Thus this has resulted car manufactures to give a deep thought and are serious about alternative ways to produce engine power.
In other words we can say that it is all about developing the car of the future, a vehicle that will be both greener and more efficient. This is when hybrid car makes its entry. Hybrid car these days is gaining popularity as it is not only cheap but also easily affordable. This means owing this car won’t create any environment hazards and also won’t burn hole in your pocket. But is hybrid car reliable and bankable option? The answer is somehow yes, considering current trend of auto industry
A car with Hybrid technology has two engines, side by side, under the bonnet. This means an electric engine here and a petrol engine there. Seeing today’s cars we come to know that majority cars driven by one or the other engine. This means not that cost effective. Thus, for better mileage and maximum performance, you get them both chiming in together, so you get more power. This can only be found in hybrid cars. That’s why people prefer them over others.
In hybrid car the electric engine also charges the batteries, and that neatly gets you around the old problem of electric cars of having to plug it into the mains overnight. This means no need to worry about recharging too. But one of the biggest disadvantages attached with hybrid cars is that they needed big, heavy battery packs which took up all of the back seat. But this is also now rectified as now you get a full four-seater capacity and enough room in the luggage space for two or three small dogs or maybe even one really big one.
Thus, we can now say that hybrid car is the best and safe option to go for. Visit Author's site to learn more on hybrid car technology.

Along the top of your keyboard is a row of keys numbered F1 to F10 or F12. Even though you may never use them, they do have function. In fact, the F stands for Function and they are called Function keys. Below is a list of what each key does. After the list is a trick that you can use Function keys for.
Most of the items on the list below apply only to Windows and Windows' programs, especially Windows Explorer and Internet Explorer.
Some programs have their own set of functions that they have assigned to the Function keys. You can find these in the menu of the program. The menu items which are assigned a function key have the corresponding function key designated after the item name. If you press that function key, you can perform that function without using the menu or buttons. The program's help or manual should also tell which functions are assigned to the function keys. You might want to try each one of these as you read through them.
Function Keys for Windows
* F1 - Opens Help for the currently displayed program (this does not work on all programs).
* Windows Logo key and F1 - Opens Windows' Help.
* F2 - Highlights the name of a selected object for renaming in Windows Explorer, desktop, and some other Windows' programs. First, you need to select an item that can be renamed (like, a file or shortcut). After pressing F2, you can then type what you want to rename the object to.
* F3 - Brings up Search in Windows Explorer.
* F4 - Drops down the Address bar in Internet Explorer showing your previous locations. This allows you to scroll down and select one.
* Alt and F4 - Closes the currently displayed program.
* F5 - Refreshes the view in Windows Explorer, Internet Explorer (in other words, it looks at the source again and reloads the contents), and other programs. In MailWasher it checks the mail (which I guess would be a kind of refresh).
* F6 - moves the cursor around the structure of a program. Pressing it may cycle you from window to window or from place to place within the program. In Windows Explorer it moves you from the left pane to the right pane and back. This is similar to what the Tab key does.
* Alt and F6 - Switches between multiple windows in the same program (for example, when the Notepad Find dialog box is displayed, ALT+F6 switches between the Find dialog box and the main Notepad window).
* F7 - does not have any functionality in Windows. It may be used in individual programs.
* F8 - accesses Safe Mode if pressed at the right time while the computer is starting. Safe Mode is a trouble-shooting mode, which will start the computer with minimal drivers.
* F9 - does not have any functionality in Windows. It may be used in individual programs.
* F10 - Changes the focus to and from the menu. Pressing the Alt key will also do this. Once the focus is on the menu items, you can use the arrow keys to navigate to an item and the Enter key to select it.
* Shift and F10 - brings up the popup menu in Windows Explorer much like right clicking on an item does.
* F11 - Switches between regular screen mode and full screen mode. Full screen mode is like a maximized screen but with more screen space and less toolbar controls
* F12 - does not have any functionality in Windows. It may be used in individual programs.
You may have noticed that some of the Function keys are not used (F7, F9, F12) in Windows. That doesn't mean that they can't be used. You can assign them or any other key combination to quickly run programs that you frequently use. Here are instructions for doing that.
1. Locate the shortcut of that program. The Start menu is a good place to find shortcuts (every icon in the Start menu is a shortcut). If the program doesn't have a shortcut, create one.
2. Right click on the shortcut and select the Properties item from the popup menu.
3. The Properties dialog will open. Go to the Shortcut tab.
4. Put the curser in the Shortcut key textbox and press the Function key or key combination (like Alt + Ctrl + 2) which you want to use to start the program.
5. The Function key name or key combination name will appear in the box.
6. Click on the Apply button (or the OK button) and close the dialog.
After you have done this, whenever you press that Function key or key combination, that program will start. Please note that if you use a Function key or key combination that is already used by Windows or other programs, it will no longer work in Windows or the other programs as it used to and will instead start your program.
To disable this, follow the above instructions but press Backspace or Delete in the Shortcut key textbox.
The Function keys are there to make your life easier. Now you can start using them.
Innovation means technological change. The technology change results in practical implication or commercialization, it does not mean just generation of ideas. The importance of technological innovation in today's competitive economy is very clear, as today the worldwide economy depends on technology and technological innovation to an extraordinary degree.
Technological innovation plays important role in the economical growth of any country. Us, Japan, and other European countries are developed only due to there technological progress. In recent years, Singapore, India, China and many other countries are advancing dramatically due to technological innovations and progress. High technology companies are a significant and growing component of the economy. The competitive of these companies depends on technological innovations. Innovations improves standard of living. Developments in medical and pharmaceutical technologies have delivered extensive returns in health and life span.
Technological innovation involves tech mining. Tech mining includes understanding the technological innovation processes to track them more effectively and get informed about latest happenings and make valuable business decisions about R&D and subsequent implementation and adoption choices.
Innovation is defined as the process by which technological ideas are generated, developed and transformed into new business products, process and services that are used to make a profit and establish marketplace advantage. A better understanding of the innovation process is essential to figure out empirical measures deriving from innovation activities to generate actionable technological intelligence.
Tech mining is done through data or information extraction from multiple data sources, compilation and analyzing the results and represents key findings in actionable visual representation for easy understanding to what is happening now and predicting the future technologies.
Various types of technology analysis that can be aided by tech mining is as follows:
(A) Technology Monitoring (technology watch) - cataloguing, characterizing, identifying and interpreting technology development activities
(B) Competitive Technological Intelligence (CTI) -exploring out "Who is doing what?"
(C) Technology Forecasting-anticipating possible future development paths for particular technology domains
(D) Technology Road mapping - tracking evolutionary steps in related technologies and, sometimes, product families, technology diversification and technology tree
(E) Technology Assessment - anticipating the possible unintended, direct, indirect, and delayed consequences of particular technological changes
(F) Technology Foresight - strategic planning (especially national) with emphasis on technology roles and priorities
(G) Technology Process Management - getting people involved to make decisions about technology
(H) Science and Technology Indicators - time series that track advances in national (or other) technological capabilities
Reasons to Do Tech Mining
- Forecast likely development paths for emerging technologies - identify new products, research or service opportunity
- Identify competitors, or collaborators, at the "fuzzy front end" of new product development - keep tract of your competitor's activity for market dominance.
- Identify potential customers for your intellectual property ("IP") - new licensing, collaboration, acquisition and merger opportunities.
- Discover additional application arenas for the outputs of your R&D - identify how to develop new products and services from your existing business processes, without inventing more.
- Gauge market potential for prospective technology-based products and services
- Be a wiser consumer of others' science and technology
- Manage the risks of technology development and implementation based on better information.
