Abstract

CARACTERIZADO PORQUE INCLUYE DOS CONDUCTORES ELECTRICOS SEPARADOS UBICADOS SOBRE UN MATERIAL DE BASE AISLANTE; Y, UNA PLURALIDAD DE MEDIOS RESISTIVOS INDEPENDIENTES QUE SE EXTIENDEN ENTRE LOS CONDUCTORES ELECTRICOS, PARA LIBERAR ENERGIA CUANDO SE APLICA UNA CORRIENTE ELECTRICA A LOS MEDIOS RESISTIVOS. DONDE EL MEDIO RESISTIVO ESTA EN FORMA DE ELEMENTOS TIPO PUENTE DE UNA SUSTANCIA RESISTIVA ABSORBENTE COMO AQUELLAS QUE SE USAN EN LA FABRICACION DE CIRCUITOS INTEGRADOS, PARA CREAR PLASMA CUANDO SE APLICA LA CORRIENTE ELECTRICA. ADEMAS EL MEDIO RESISTIVO ESTA CONSTITUIDO POR UNA COMPOSICION CONDUCTORA DE EXPLOSIVOS O PIROTECNICACHARACTERIZED BECAUSE IT INCLUDES TWO SEPARATE ELECTRICAL CONDUCTORS LOCATED ON AN INSULATING BASE MATERIAL; AND, A PLURALITY OF INDEPENDENT RESISTIVE MEDIA THAT EXTEND BETWEEN THE ELECTRICAL CONDUCTORS, TO RELEASE ENERGY WHEN AN ELECTRICAL CURRENT IS APPLIED TO THE RESISTIVE MEDIA. WHERE THE RESISTIVE MEDIA IS IN THE FORM OF BRIDGE TYPE ELEMENTS OF AN ABSORBING RESISTIVE SUBSTANCE SUCH AS THOSE USED IN THE MANUFACTURE OF INTEGRATED CIRCUITS, TO CREATE PLASMA WHEN ELECTRIC CURRENT IS APPLIED. ALSO THE RESISTIVE MEDIA IS CONSTITUTED BY A CONDUCTIVE COMPOSITION OF EXPLOSIVES OR PYROTECHNICAL
