Abstract

Una etiqueta universal (1) para usarse con una variedad de lectores de diferentes diseños comprende el transductor (3), un modulador (11) conectado a través del transductor (3), y medios de control (13). Los medios de control (13) hacen que el modulador (11) excite el transductor (3) con una pluralidad de formas de onda de mensaje diferentes después de la interrogacion por un lector, la identidad de la etiqueta es inclinada en cada una de las formas de onda de mensaje. Las formas de onda de mensaje pueden ser transmitidas ya sea simultáneamente, de manera secuencial, o de ambas formas. Una forma de onda de mensaje está comprendida de una secuencia de segmentos de forma de onda contiguos, cada segmento de forma de onda representa el valor de un grupo de N bits; N es un numero entero. Un segmento de forma de onda es una señal periodica caracterizada por los parámetros de frecuencia, fase y amplitud. Los segmentos de forma de onda que representan los valores de un grupo de N bits se diferencian por los valores de al menos un parámetro.
