Abstract:
An engineering data acquisition device for use in an un-referenced orthogonal axis system in space and time, represented by vectors Xâ€², Yâ€², Zâ€², and time Tâ€², which has a known relationship to a referenced orthogonal axis system defined by the axes X, Y, and Z, time T, and in which a known relationship is developed between said time Tâ€² and said time T, comprising:one or more transducers laid substantially along said Y axis of said referenced orthogonal axis system, which have uni-axial sensitivity to an applied dynamic force applied parallel to said Z axis and normal to said Y axis, and which produce time referenced electric signals in response to forces applied at right angles to a physical displacement of structural material developed within a structural mass; an amplifier, for amplifying said time referenced electric signals from said one or more transducers; a filter, for discriminating against unwanted signal components from said time referenced electric signals; and a computer for sensing said time referenced electric signals and for developing a proportional kinetic energy signature for said applied dynamic force; wherein said one or more transducers are operatively connected to said structural mass, and produce said time referenced electric signals in response to rotation of said structural mass and said one or more transducers through a magnetic field.
