     Fujitsu, a Japanese technology company, has created a system capable of simultaneously(同时地)

charging multiple portable electronic devices such as mobile phones, digital cameras and laptop

computers without the need for cable connections.

     Electric cars users may also eventually be able to charge their vehicles wirelessly using the same

technology, said the company, which developed a sample system at Osaka Prefecture University.

Claiming to be the world's first of its kind, the technology works on the basis of the transmission of

electricity using magnetic fields between the charger and the electronic device.

     The system enables wireless charging at distances of up to several meters. With the final aim of

installing public "charging spots" on the streets in order to enable easy charging around the clock,

scientists at Fujitsu Labs are planning to commercially sell products incorporating the new wireless

charging system as early as 2012 but have not yet decided how much they would cost.

     "This technology paves the way to integrating compact wireless charging functions into mobile

phones and enabling multiple portable devices to be charged simultaneously without any restrictions

on their position relating to the charger," the company said in a statement.

     Mobile phone users in Japan can currently charge their batteries using the disposable portable

plugin batteryoperated device, available at most train stations and convenience stores. However,

phone companies warn long time use of it can damage the phones.

     The company added, "We are also looking at applying the results of this work to fields other

than portable electronics, including power transmission between circuit boards(电路板)or computer

chips,and providing mobile charging systems for electric cars."
