Abstract
"UNIDADE AUTOMáTICA DE CONTROLE DE INTENSIDADE PARA UM SENSOR DE UMIDADE E SENSOR DE UMIDADE PARA DETERMINAR A PRESENçA DE UMIDADE SOBRE A SUPERFìCIE DE UM MATERIAL TRANSPARENTE". Uma unidade automática de controle de intensidade para uso em um sensor de umidade a qual percebe a umidade sobre a superfície de um material transparente. O sensor de umidade inclui um ou mais emissores para produzir um sinal do emissor o qual é influenciado pela umidade sobre o material transparente, e um ou mais detetores para receber os sinais do emissor. A unidade automática de controle de intensidade ajusta a intensidade dos sinais do emissor para se adaptar aos materiais transparentes que possuem diferentes transmitâncias. A unidade automática de controle de intensidade inclui um comparador para comparar a intensidade dos sinais dos emissores recebidos pelos detetores com um sinal de referência predeterminado e um contador que se comunica com o comparador para produzir uma saída do contador. A unidade automática de controle de intensidade também inclui um acionador do emissor para fornecer potência aos emissores em uma quantidade que determina a intensidade dos sinais do emissor, e um gerador de sinal de controle da intensidade do emissor que se comunica com o contador e o acionador do emissor para controlar a intensidade dos sinais do emissor.
