Abstract

''APARELHO E PROCESSO PARA CONTROLAR UM SINAL DE NOTIFICAçãO PRODUZIDO POR UM DISPOSITIVO ELETRôNICO". Um telefone tem um receptor, um transmissor, uma interface de controle, um processador de áudio e um microprocessador. O processador de áudio inclui um processador de sinal digital, uma unidade de entrada de áudio acoplada a um microfone, uma unidade de saída de áudio acoplada a um alto-falante e um controlador de sinal de chamada acoplado a um transdutor/campainha. Quando uma chamada que entra é recebida, o processador de áudio amostra o sinal de entrada do microfone, que é indicador de ruído ambiente, e realiza uma análise espectral do ruído ambiente. O processador de áudio, então, ajusta a freqüência da chamada e o volume da campainha em resposta ao espectro do ruído ambiente e ao nível de ajuste do controle de volume da chamada ajustado pelo usuário.
