Training system null battery power source of skin diving which has the portable data collector and the same device

摘要

PURPOSE: To enable a movement locus of a skin diver to be reproduced correctly. ;CONSTITUTION: DTU (a tracing unit) is set on a check-in unit 2 and is initialized for beginning data recording before diving a diver carrying a movement data collector, then the diver begin to swim or dive. The movement of the diver in swimming is detected by three dimensional acceleration sensor 10 and three dimensional angular speed sensor 13 of the DTU 1, without recording values detected by the sensor and included within a designated very small value range, only significant detected values out of the range are recorded. After that, the data taken in by DTU 1 until check out operation of completion is performed are analyzed by a data analyzer 3 and the whole process of skindiving is dynamically displayed and reproduced in time series on the three dimensional map of a reproducing device 4 based on the analyzed data.;COPYRIGHT: (C)1995,JPO
