New films to protect your phones from water


Researchers in Georgia have created a new way to produce better films using atomic layer deposition that will safeguard your phone's high-tech organic light-emitting diode display from every whiff of oxygen or molecule of water vapor.

Existing methods for manufacturing these high-performance barriers aren't perfect . Due to the way they're made, they often have small defects, resulting in tiny holes that let in water or oxygen.
Samuel Graham and his colleagues at the Georgia Institute of Technology have created new barrier films that can protect electronics in very harsh environments — when submerged in salt water for months, for example. Graham said that by creating such barrier films, we are able to extend the lifetime and reliability of electronic devices.

Apple stores may get iPhone-connecting transmitters in Share Apple is likely to equip its retail stores with transmitters that connect to visitors' iPhones and provide messages based on the products of their interest.     The iBeacon transmitter system has been designed to enhance the shopping experience of people who visit the store. According to Cnet, the transmitters would connect to a user's iPhone and send messages as the user takes a look around products in the store, offering more product information or invitation to workshops. The report said that stores such as Nordstrom experimented with such a system before bringing in the wrath of customers who discovered they were being tracked as they wandered through the store.

1. Irrelevant Elements By far, the biggest issue I come across with new site launches is this: They use too many elements that bring no real value to the audience. In fact, these often just downgrade user experience considerably. There are too many crowded designs and too much text on one page. There are too many icons and photos. Does your site really need a search bar? Do you really need to show the tag cloud in your blog sidebar? Think hard. What are the 20% of elements that bring 80% of the results you're after? Start there. Always have a sound reason for adding new features, bells and whistles. Never add more stuff just because it seems "cool and hip." - Juha Liikala , Stripped Bare Media 2. Flash Intros Flash intros are annoying for the customer, take too long to load, don't work on Apple mobile devices and are not recognized by Google. It is best to avoid them entirely. - Josh Weiss , Bluegala 3. Photo Carousel A lot of sites stil

How noise-cancelling technology works for headphones    Bose pioneered the concept of noise-cancelling headphones way back in 1989 after more than 10 years of research. ET explains how this fascinating technology works. Noise cancellation in the car You may have experienced that some cars are quieter than others - this is because of the special attention paid to insulating materials (special laminated glass for example). However, there's only so much that passive noise isolation can accomplish inside the complicated acoustics of the car. That's why luxury carmakers have been implementing active noise cancellation for a quieter cabin. The same active noise cancelling technologies used in headphones can be easily implemented in a car. See image for details. How it works Simply put, active noise cancellation works by 'listening' to unwanted ambient sounds, and then producing a s
