Abstract

UN ROTULO PARA USO EN UN CONJUNTO OPERATIVO MAGNETICO DE VIGILANCIA DE ARTICULOS, CONSTITUIDO POR: UN MEDIO DE ANTENA QUE RESPONDE A UN CAMPO MAGNETICO; Y MEDIOS PIEZOELECTRICOS QUE RESPONDEN A DICHO MEDIO DE ANTENA PARA GENERAR UNA SENAL ACUSTICA AUDIBLE. DICHO MEDIO PIEZOELECTRICO TIENE UNA FRECUENCIA RESONANTE ACUSTICA; DICHO MEDIOS DE ANTENA Y DICHO MEDIO PIEZOELECTRICO ESTAN CONECTADOS DE MODO DE FORMAR UN CIRCUITO QUE RESPONDE A SENALES DE DICHA FRECUENCIA RESONANTE ACUSTICA; Y DICHA SENAL ACUSTICA AUDIBLE SE ENCUENTRA A DICHA FRECUENCIA RESONANTE ACUSTICA.A SIGN FOR USE IN AN ARTICLE SURVEILLANCE MAGNETIC OPERATIONAL SET, CONSTITUTED BY: AN ANTENNA MEDIA RESPONDING TO A MAGNETIC FIELD; AND PIEZOELECTRIC MEANS THAT RESPOND TO SUCH ANTENNA MEANS TO GENERATE AN AUDIBLE ACOUSTIC SIGNAL. SUCH A PIEZOELECTRIC MEDIUM HAS AN ACOUSTIC RESONANT FREQUENCY; SUCH ANTENNA MEDIA AND SUCH PIEZOELECTRIC MEANS ARE CONNECTED IN ORDER TO FORM A CIRCUIT THAT RESPONSES SIGNALS OF SUCH ACOUSTIC RESONANT FREQUENCY; AND SUCH AUDIBLE ACOUSTIC SIGNAL IS AT SUCH AN ACOUSTIC RESONANT FREQUENCY.
