WIRELESS CHARGING

What is Wireless Charging And How Does It Work?

 wireless charging, it has been around since the late 19th century, NikolaTesla demonstrated magnetic resonant coupling – the ability to transmit electricity through the air by creating a magnetic field between two circuits, a transmitter and a receiver.


                                                   
Wireless Charging

Nowadays charging technology is getting big this is why charging technology Is all the rage now, and the new big thing is wireless charging .it's just convenient to use.

Near the end of the 19th century, engineering mastermind Nikola tesla showed that two powerful magnetic fields can slightly transfer energy between their sources when they interfere with each other. but this wireless charging is experimented by tesla in the 19th century but this wireless charging has been built into smartphones since the Nokia's Lumia Windows phones such as the 820 and 920 gaining wireless charging support in 2012.  

Mechanism

                                         

             

In wireless charger, there is an inductive coil through which  the  power is supplied either by USB or c-type cable. The inductive coil produces an electromagnetic field when current is passed. Similarly, there is an inductive coil in the mobile phone which receives the electromagnetic field and converts to electricity. Nowadays reverse charging is possible. (eg: Samsung mobiles)The charging speed efficiency varies according to the length and thickness of the inductive coil. In which there are two types of wireless charging system are in use.

 Reverse Charge

                                                    

QI System

        Qi is an open standard system in this system wireless power transfer using inductive charging over up to 4 cm. The system uses a charging pad and a compatible device, which is placed on top of the pad, charging via resonant inductive coupling.

                                                      

AirFuel Alliance Standards

         This AirFuel Alliance Standard is very interesting and this is different form QI standard by this method we don't want to place our mobile in the charging pad, mobile will starts to charge when we go near the charging pad, it is not in use nowadays but it will be in future(in 10-20 yrs). many companies (Tesla, oppo...)  got pattern rights for future coming products based on these standards.in futures these standards are mostly used in airports and automobiles.

VIRTUAL REALITY(VR)

  what is    VIRTUAL REALITY?     Immerse Yourself inside your imagination with Virtual Reality.      VirtualReality                                                                                      Virtual Reality is a complete immersive experience, altering your perception to make you feel like you exist in that world. It provides users with a fully digital environment with no elements from reality. Requires wearing a VR headset or additional equipment to get fully immersed in the experiences. Users might experiences issues with mobility while remaining fully immersed in a virtual environment, such as the inability to feel objects when ‘picking’ them up. Adoption to technology is still limited, but inventors are looking...

what is UFS?

   w hat   is   UFS ?                                    Universal Flash Storage(UFS) is an advanced storage type designed for smartphones and digital cameras.UFS offers read and write speed (up to 530MBPS) that are comparatively faster than eMMC(embedded MultiMedia Card).UFS was primarily to deliver SSD(SolidStateDrive) like speed on mobiles.UFS is to bring higher data transfer speed.UFS is developed by JEDEC solid-state technology association, the first UFS v1.1 came into existence in 2012.                                                                                          ...
