58 of Americans survey online before shoppping online
Pew Internet and American Life Project has just released the latest the survey results of online shopping habits of Americans . One of it: 58% of Americans said that they have investigated before buying anything online, and this proportion is only 49% in 2004. In these respondents, who call themselves Internet users rose to 78%.
In addition, to investigate not only the proportion of shopping before the increase, and the network of people has also increased the frequency of the investigation.
21% of adults engage in every day of this survey, one in 2004 compared to only 9%.
American research, reviews, online shopping more and more
In addition to the website to read the description of products and services in addition, many people also add a Review of information, analysis, views of the product, especially through social networking sites. 24% of Americans said they would comment after buying things.
The Pew study also online shopping of American spending habits have been studied. There have been online shopping experience of Americans in May 2000 from 36% to 52% now. Meanwhile, online booking air tickets and hotels from 22% to 52%.
The study also found that study habits between men and women of similar, but high-income groups than low-income populations of the network to investigate more. High income and highly educated people post reviews and comments more frequently.
Many Americans are shopping online before comparing the price, quality and product review. Even if the end did not buy the site, but in the store shopping, they will advance the investigation and decision-making on the Internet.

Electronic Privacy Screen Of Dell Protect Privacy In Public Places
October 2008, Dells provides a new security technologies which is Electronic Privacy Screen for its next-generation Latitude business notebook flagship model E6400. However, there are still few user who understand the function so far. Here I am explain it again today.
Over the past few years, display manufacturers have been increasingly viewing angle will be as a promotional selling point. If you use at home, of course, the higher the better viewing angle, but in the workplace, coffee shop, airport or other public places, privacy and data security issues become more exposed. Members may have noticed that some of my colleagues has focused laptop privacy screen labeled anti-spy film.
Currently, only Dell Latitude E6400 can support electronic security shield technology, Dells official website users can be customized when ordering. This notebook is equipped with software-driven display screen can create a pixel-based pattern, so it can narrow the viewing angle the screen to avoid being shown the privacy of important data or content is sweeping others. This feature is activated, the user only in the notebook before had just being able to clearly see the displayed content, and in the side, the content is completely unable to see.
Electronic Privacy Screen almost have nothing to do with the display brightness, it can be activated just by the shortcut key combination (FN + E) or the Dell ControlPoint software. The consumers who focus on data security and privacy of may try it.

Process formation of RGB signal on TV
Basically the UOC is equipped with RGB or YUV input from external, so it is possible to use the DVD input. Selection of these inputs can be done internally within the IC. But in the G7 and G7A chassis input YUV signal is not used, so in the ground.
RGB signal processing flow is described according to the image below :

| Diagram of the formation RGB signal |
1. Signal Yint, uint, and Vint is derived from a series of color decoder and Y / C switch is fed into a series of YUV selector 1.
2. From YUV selector, sub-carrier signal color (U and V) is inserted into the chain matrix. In this matrix series component sub-carrier signal BY of the color (U signal) and BY component of sub-carrier signal color (V signal) in separate. Here the color difference signal in the form of the color sub carrier. GY signal generated by a combination of color difference signals RY and BY.
3. From YUV selector, luminan signal is passed to a series of black stretch. The working principle is to sharpen the series of black stretch black levels. Gray color in a certain percentage in drag to a black color so the color is sharper.
4. Three color difference signals (RY), (BY) (GY) and luminan signal (Y) are mixed and processed in RGB adder circuit to produce three primary colors red, green and blue (RGB).
5. RGBOSD formed in the UOC IC is used to display the OSD text. The selection and arrangement RGBOSD kontrast between RGB and composite signals is done by way of a switch by the internal microprocessor.
6. Three output video signal (RGB signal) is assumed as the current that flows to the CRT cathode. Drive level coming into the cathode tube is always diadjust by CCC loop (Continues Cathode Calibration) and feedback currents in pass to Black Current Input pin 50.
7. CCC loop works as a stabilizer against the black level and drive the cathode in a loop (continuous) to the RGB signal in order to obtain the proper offset and gain.
