Abstract

"MéTODO PARA DETERMINAR A PRECISãO DE UM SENSOR DE PRESSãO EM UM CONSOLE CIRúRGICO". Um método para determinar a precisão de um sensor de pressão em um console cirúrgico é apresentado. O método envolve ativar um atuador linear de forma que seu êmbolo seja linearmente deslocado por uma extensão predefinida, e medir a força exercida pelo êmbolo sobre um membro não-complacente. A precisão do atuador linear e o êmbolo são determinados comparando a força medida na etapa de medição com uma força predefinida.
