Apple developers have used various existing playing technologies of creating pseudo hologram.

Technology is contains of 3 parts: display system, which creates a primary 3D-image; an optical system that converts it into a 3D-image of the second level in the air; set of sensors that record data input by the user. The support system includes a data processing unit and control circuits to provide feedback.

Before it, Japanese developers have created a screen, which is float in the air, and you can move, touch  objects that are on the screen. The technology is based on sensors that are sensitive to the movement of hands, and the movement is automatically transferred to the processing. It's similar technology.

How to properly charge the iPhone and iPad

Charging of mobile devices for active users has become a daily necessity. Sellers are advised to charge accumulators only when the battery is completely exhausted. Is it right?

Actually needed to charge battery not more than 50%. Always hard to keep an eye on this, so identified optimal range of 40-80% charge level. Each rechargeable battery cell has a particular load. This load is directly proportional to the level of charge: the higher the charge - the greater the load. A load is known to lead to depletion of the productive resources. It is therefore desirable to charge mobile devices up to 100% charge.

Battery is constantly charged at 100% charge level works only 300-500 cycles, while battery charge up to 40-80% will working about 1200-2000 cycles.
