Abstract
"APARELHO PARA A MEDIçãO DE GRADIENTES GRAVITACIONAIS". A presente invenção refere-se ao aparelho para a medição de gradientes de gravidade quase estáticos, que compreende: uma corda flexível (1); e meios de saída para a produção de uma saída, a qual é uma função dos referidos gradientes de gravidade; e onde a corda é fixada (2, 2<39>) em ambas as extremidades; e onde o aparelho compreende meios de detecção (L1, L2) para a detecção dos deslocamentos transversais da referida corda a partir de sua posição de referência não perturbada, devido a um gradiente de gravidade em torno da referida corda; e os meios de saída respondem ao deslocamento detectado para a produção da referida saída, a qual é uma função do gradiente de gravidade; o aparelho ainda compreendendo um meio (30) montado em uma posição correspondente ao ponto médio entre as extremidades fixas da corda e construído para evitar movimentos da referida corda, os quais correspondem a todos os seus modos ímpares (começando a partir do modo C), enquanto não afeta pelo menos o movimento da referida corda, o qual corresponde ao seu segundo modo fundamental (modo S).
