Patent ID: 7502594

Claim:
A wireless communication system with power regulation feedback to improve robustness of wireless communication transmissions between a receiver and active emitter irrespective of distance separation therebetween, comprising: the receiver being adapted to receive an RF modulated data signal, the receiver comprising: a converter for collecting RF energy from the received RF modulated data signal and converting the RF energy to an induced voltage signal; a first demodulator for demodulating the received RF modulated data signal; a first processor for receiving as input the demodulated RF data signal and the induced voltage signal and generating an RF responsive data signal including the induced voltage signal; a first modulator for receiving as input the RF responsive data signal and generating an RF modulated responsive data signal; the active emitter in wireless communication with the receiver for receiving the RF modulated responsive data signal, the active emitter comprising: a second demodulator for demodulating the received RF modulated responsive data signal; a second processor for receiving as input the demodulated RF responsive data signal, the second processor generating new data and at least one of adjusted maximum and minimum bit voltage levels of respective logical high and low bits based on the induced voltage signal of the demodulated RF responsive data signal; a data converter for receiving as input the new data and the at least one adjusted maximum and minimum bit voltage levels from the second processor, the data converter producing as output a converted data signal at an adjusted voltage level based on an average of the adjusted maximum and minimum bit voltage levels; an RF carrier generator for generating an RF carrier wave; and a second modulator for receiving as input the converted data signal and the carrier wave, the modulator generating as output a new RF modulated data signal to be transmitted to the receiver.
