Abstract
Un circuito de retardo electronico (10) util para el inicio retardado de detonadores ilustra diferentes características novedosas que puedencombinarse, incluido un oscilador novedoso (34), un circuito temporizador programable (32) y unci rcuito de control de ciclo (46). El oscilador (34)genera una senal de reloj determinada por la tasa de descarga de un capacitor (34a) con relacion a una tension de referencia REF. Un segundo capacitor (34b)se carga a una tension que excedeREF, y cuando el primer capacitor (34a) cae por debajo de REF, se genera una senal interna y se conmutan los capacitores,de manera que el primer capacitor se carga mientras que el segundo se descarga. Un enganche (34f) genera impulsos de reloj enrespuest a a las senales internas.El circuito temporizador programable (32) incluye un contador de transporte ondulante (38) y el banco de programas (40) que carga una cuenta en elcontador al inicio. Cada etapa del contador (38) tiene entradasseparadas p ara las senales fija y de vía libre, y el banco de programas (40) tiene uncircuito de regulacion y un circuito de vía libre para cada etapa del contador. Cada circuito de regulacion genera una senal de duracion fija y cada circuitoderegulacion pued e generar una senal de dos duraciones diferentes, una de las cuales excede la duracion de la senal de vía libre. Durante la programacion,se elige la senal establecida de duracion corta o larga y, al cargar el contador, lasenal más prolongad a fijada o de vía libre determina el estadode la etapa del contador. El circuito de control de ciclo (46) controla una compuerta (34h) que permite que los impulsos del oscilador incrementen elcontador (38), pero cierra lacompuerta (34h) ante una interrupcion temporaria en la alimentacion que evita que se vuelva a poner en funcionamiento el
