Abstract: An automated interactive form of data collection is disclosed that addresses the deficiencies of the standard method of personal interviews and the typical paper-based and computer-based surveys. Subject Matter Experts (SMEs) can provide data in a faster, more accurate and comprehensive manner, while providing the justification of their responses immediately. Using these data, an instructional analyst can continue the Instructional Systems Design process utilizing SME data that are complete and conclusive, without the need for extensive follow-up questioning. The database files generated by the survey software are available to the analyst for analysis and inclusion in the resulting training system analysis document.

Abstract: Disclosed is self-paced, system-level familiarization training customized to the trainee's individual training needs that is sufficiently flexible to accommodate individuals with varying levels of expertise. Training is accomplished by determining or directing the location of students relative to an on-board system, then stimulating the correct Interactive Media Instruction (IMI) based on that location. Effectiveness is dependent on the factors; location technology, IMI, and movement algorithm; and, the interaction between these three factors.

Abstract: Disclosed is an onboard, on-the-job, communication interface system that can dynamically provide information and personnel location on request, anywhere, anytime. The system can connect to an Intranet or Internet using a wireless LAN.

Abstract: A method for determining the approximate resonance frequency of a structure urrounded by a compressible fluid includes the steps of: (1) performing analysis to determine in-vacuo frequencies and mode shapes of the structure; (2) selecting an in-vacuo mode of interest, (3) computing an influence matrix at the eigenfrequency of the selected mode of interest; (4) combining the computed influence matrix with structural stiffness and mass matrices from a finite element program, and using the modified matrices computing eigenvalues of the structure, including eigenvectors; (5) selecting from the computed eigenvectors a computed mode having substantially the same displaced shape as the in-vacuo mode of interest; (6) determining the eigenfrequency of the selected computed mode; (7) determining any difference between the computed eigenfrequency of the selected computed mode and the in-vacuo eigenfrequency of the selected in-vacuo mode of interest.

Abstract: A low frequency flex-beam underwater acoustic transducer has a base, a flexible beam having one end cantilever mounted on the base, and piezoelectric driving means, for flexurally driving the beam. The piezoelectric driving means operates in the k.sub.31 and/or the k.sub.33 mode.
