by John Toon, courtesy Georgia Institute of Technology -Aug. 11, 2013 — Researchers at the Georgia Institute of Technology want to put your signature up in lights — tiny lights, that is. Using thousands of nanometer-scale wires, the researchers have developed a sensor device that converts mechanical pressure — from a signature or a fingerprint — directly into light signals that can be captured and processed optically.
The sensor device could provide an artificial sense of touch, offering sensitivity comparable to that of the human skin. Beyond collecting signatures and fingerprints, the technique could also be used in biological imaging and micro-electromechanical (MEMS) systems. Ultimately, it could provide a new approach for human-machine interfaces.
“You can write with your pen and the sensor will optically detect what you write at high resolution and with a very fast response rate,” said Zhong Lin Wang, Regents’ professor and Hightower Chair in the School of Materials…

Last month, we started an E-Commerce project to one of my partner. We encountered and solved so many problems for the project. One of the most important element for an Easy to Use E-commerce Web application is an easy shopping cart. The first idea on my mind is to build my own Shopping Cart System. With a near deadline and little experience in the system, honestly we failed.
The next week, we decided to search for some JQuery plugin to solve this problem and the easiest plugin to configure is the smart cart plugin. Here is the page, http://techlaboratory.net/smartcart.
The Smart Cart is uses an array variabel to pass the shopping cart list. We can easily add products list from database and easily inserts some products orders to database. Easy to use and easy to configure display. The E-Commerce Project front office is lot more interactive with this Smart Cart plugin and our back office report is easy to print with FPDF PHP plugin that we have posted before.
For some technical problems when using the Plugin, please comments here. We will help based on our experience when using the plugin.
