this kind of cell phone jammer can be continuously used for 12 hours at most

Normally, this kind of cell phone jammer can be continuously used for 12 hours at most.
Transparent separation point with many of the small (less than thousandths of an inch) between the two conductive layers separated by insulating them. When the fingers touch screen, the two conductive layers, usually insulated from each other in the touch position with a contact, a conductive layer connected to the Y-axis direction of the 5V voltage field, making the detection of the voltage resistive touch screen profile structure from zero to non-zero controller detected this connected to the A / D converter, and voltage values compared to the Y-axis coordinates of the touch point and 5V, and reached the same X-axis coordinates, this is the most basic principle of all resistance touch screen technology. The key lies in the material of the resistive type touch screen technology. Then, the manufacturer owns its characteristics of cell phone jammer .These companies need to continue the development of effective development strategies based on environmental changes, continue to examine our own capacity to adapt to competing demands. 2PND destined predict will exit the market, people trying to growth, development and success of technology is a very common phenomenon, rarely accurate predictions. Founder and CEO of Digital Equipment Corporation (DEC), Ken? Olson in 1977 and said: "We have no reason to think that people will need a home computer." IBM founder Watson? Thomas also insisted that, "Perhaps The computer will be able to meet the entire world market. "Today, when you see the results of the developments, you may have these projections with contempt.
The seamless integration of mobile phones and car equipment will become a trend; PNDs will be doomed from the historical stage. However, perhaps such as Olson and Mr. Watson, as I said is wrong. PND is most suitable for portable navigation devices, mobile phone navigation and embedded navigation plays a role, they have their own unique advantages. Which a system will be approved will depend on the division of the market and grasp of user needs. Let's briefly review each solution, may be able to discover the best solution. We can see that the PND is the explosive growth in the past four years. Penetration has reached a new height. Estimated that in 2013, 96 percent of smart phones will integrate GPS functionality. After such a long time, the customer should shut off cell phone jammer for a while.
