Abstract

"APARELHO PARA COMUTAR ENTRE UMA PRIMEIRA BATERIA E UMA SEGUNDA BATERIA REMOVìVEL, E, CIRCUITO PARA SENTIR A PRESENçA DE FLUXO DE CORRENTE ATRAVéS DE UM CIRCUITO". Um aparelho para perceber a presença de uma bateria auxiliar conectada a um telefone celular é descrito. Uma bateria interna e uma bateria auxiliar removível são conectadas ao sistema de energia do telefone celular através dos primeiro e segundo comutadores respectivamente. A conexão da bateria auxiliar cria um fluxo de corrente que é detectado por um circuito sensor de corrente que gera um sinal de corrente indicando a detecção do fluxo de corrente. Um circuito sensor de voltagem determina se a bateria auxiliar pode fornecer um nível de voltagem predeterminado e gera um sinal de voltagem indicando os resultados desse teste. Um processador então utiliza os sinais do circuito sensor de voltagem e o circuito sensor de corrente para controlar o par de comutadores para conectar as baterias principal e auxiliar ao circuito de energia do telefone celular.
