Abstract

Patente de Invenção: <B>"PROCESSO E APARELHO PARA LOCALIZAR DISPOSITIVOS TRANSDUTORES DE ONDA FLETORA"<D>. Processo e aparelho para determinar sítios vantajosos para localizar dispositivos transdutores de onda fletora em associação operativa com membros confiando para operação acústica sobre modos ressonantes de ação de onda fletora nos ditos membros. O processo compreende a excitação investigativa de ação de onda fletora acusticamente pertinente em um dito membro, e avaliação sistemática de efeitos mensuráveis relacionados com a dita ação de onda fletora excitada e correspondente ação acústica, cujos efeitos variam de acordo com a locação de transdutor de onda fletora no sentido de área do membro em questão. A excitação investigativa é por aplicação de energia acústica ao membro em questão de modo a induzir a ação de onda fletora acusticamente pertinente com dispositivos transdutores de onda fletora seletiva e operativamente associáveis no sentido de área local do membro para responder a sua ação de onda fletora e o efeito ou efeitos mensuráveis sendo de sinais dos dispositivos transdutores, ou por dispositivos transdutores de onda fletora seletiva e operativamente associáveis no sentido de área local do membro em questão de modo a induzir a ação de onda fletora acusticamente pertinente.
