Energous, Dialog Semiconductor launch small RF charging circuit, possibly destined for 'iP...
The transmitter does not send out power in all directions. Basically, the xmitter is software controlled and finds the device to be charged using blue tooth and then directs a pocket of energy to the device.DonaldRW said:If a transmitter is emitting energy in all directions, but the receiving antenna is only in one location, what percent of the radiated energy actually makes it to the receiver? How does its energy consumption compare to conventional plug in chargers?
