Abstract
<B>TERMINAL DE COMUNICAçãO DE DADOS E MéTODO DE AJUSTAR UM SINAL DE FORçA GERADO DO MESMO<D> Um terminal (102) de comunicação de dados inclui um circuito (106) de antena para distribuir um sinal de força para um dispositivo portátil de dados. O terminal abrange ainda um método para ajustar automaticamente a força vista pelo dispositivo portátil de dados sem qualquer realimentação de comunicação a partir do dispositivo portátil de dados mediante monitoração de uma características de impedância para o circuito de antena. Quando é detectada uma mudança nas características de impedância monitoradas, o terminal de comunicação de dados ajusta o nível de força para o sinal de força distribuído para o dispositivo portátil de dados.
