A Comprehensive Study Of Wireless Mobile Charger And Its Technological Advances

In this paper, we have described a mechanism to transfer a low power DC voltage from one mobile to another for the purpose of charging the phone. We have dealt with coupling coils and their resonance. Colpitts Oscillator, Full-Bridge Rectifier and Voltage Regulator circuits have been implemented. This project gives us a new and convenient option of recharging our phones at times when charging from a phone remains the only option because of the lack of having proper charging outlets. This simple idea is a feasible and inexpensive one for mobile

In the recent years, wireless technologies have taken a new dimension in the ways society lives. Wireless broadband is available to everyone. Whether the users are at home, driving the car, sitting in the park, and it would even work while people are a pleasure boat ride in the middle of a lake. And because of this, the need to have information at any time and be connected in all places, all the time has been satisfied.

A lot of the early cell phones that were made were considered to be “car phones,” because they were so big and heavy that you wouldn't be able to have it in your pocket or purse.However a revolutionary phone came out in 1983 by the name of the Motorola DynaTAC 8000x was available to the public. Compared to today’s high standards, it was considered the first real mobile phone because it was small enough to carry and not very heavy. Although The phone was very expensive it became a pop culture symbol. It showed up in the movie Wall Street and in the famous show Saved by the Bell.

The phone draws energy from a lithium ion battery. Currently, the lithium ion battery has the most energy per volume than any other battery. The lithium ion battery is also a good material to use because of it’s light weight. Another key feature of the lithium ion is its ability to recharge. However, it needs to be recharged properly. The battery needs to be fully charge; if it is overcharged or undercharged significant charging

The cell phone has transformed over the years, changing from a bulky phone to a compact device containing the capabilities of a computer. According to Russell Ware, a cell phone is “any portable telephone which uses cellular network technology to make and receive calls.” A cell phone works through a maze of cellular towers that cross the world. This connects mobile devices that allow texting and calling between two cellular devices. Motorola produced the first commercially available cell phone which officially went on sale in 1984 (Ware). This cell phone was called the DynaTAC 8000x which cost an extreme amount of money and only contained a battery of 30 minutes (Ware). Since this first masterpiece, the cell phone has advanced and developed into an entirely new object. Cell phones today contain the ability to text, call, use the internet, play games, and store files (Cell Phone).

Wireless technology means that data is sent from one computer to another through a wireless connection. Mobile technology is the way that communicates tasks which are performed. Computing on mobile technology devices, such as laptops, notebooks, PDA etc. It allows the user the flexibility to move and not be confined to the conventional desktop computer.

The initial offering of a cell phone was in the mid 1980’s. It was a car phone. It was secured by large screws to the

The first commercial Li-ion battery was produced by Sony in 1991. Li-ion batteries are favored for

What many people may be unaware is that cell phones give off radio frequency energy, better know as radio

Cell phones have changed in many ways throughout the years. First, we started with phones that we had to talk with when they were attached to a wall or they would have a line that you could only go so far with them. Then they grew to be able to travel with them, but still only being able to talk on them. They were these big things with an antenna for it to work. As technology kept growing these phones would get more

Electrical vehicles technology has been present for a while and is a proven technology that need only reshaping to meet the global need. Though, in the past, the technology had failed to compete with the internal combustion engine due to initial cost, the technology has done well in the past few years. Electric vehicle ability to reduce the emission of greenhouse gases like carbon and carbon dioxide and the advantages it enjoys such as low maintenance and running cost can enhance it market competitiveness. However, as experts try to make its charging system more efficient and its ability to store charge more long lasting, the global need continue to rise. The research proposal, therefore, aim at

This project deals with the calculation of the energy meter billing with prepaid facility by using Smartcard based on the load consumption with GSM communication . The microcontroller calculates the rupees that will be consumed by the loads as per the amount inserted in prepaid recharge card ,which acts as input and displays it on the 16X2 LCD interfaced with the microcontroller. This project thesis is also covers the recharge option on every insert of card in smart module and the power is continued to process. This project is powered by an on-board power supply takes the ac power and converts it into dc power that is fed to on-board devices and integrated circuits.
