Abstract

Un aparato de transmisión de senales, disposición de vigilancia electrónica de artículos que utiliza el aparato y método para operar dicha disposición,siendo una disposición electrónica y magnetomecánica, de senales pulsantes, que utiliza un únicoci rcuito transmisor para accionar dos o más antenastransmisoras de senales de interrogación conectadas en paralelo. Uno o más circuitos conmutables de amortiguación se proveen serie con las antenas parapromover una rápida amortiguación de lasenal de interrogación en el extremo de cada pulso de senal. El o los circuitos de amortiguación están situados paraproveer una amortiguación en el o los lazos formados por las antenas conectadas en paralelo. Cada circuito conmutable deamortiguación está formado de unaresistencia conectada entre una antena respectiva y un terminal del circuito de transmisión, así como también un elemento de conmutación conectado a laresistencia. El elemento de conmutación es mantenido en unacondición c onductora durante cada pulso de senal y es abierto en el extremo de cada pulsopara llevar la resistencia a una conexión amortiguadora efectiva con las antenas de transmisión.
