УСТРОЙСТВО И СПОСОБ ДЕТЕКТИРОВАНИЯ КОЛЕБАНИЙ ОТ МЕХАНИЧЕСКИХ УДАРОВ

摘要

The method involves determining the run time difference (49) of an impact sound oscillation (42) with the use of a timer (48). The timer receives the outputs of two impact sound sensors (44,46) and uses the determined run time difference to determine the origin (50) of the impact sound oscillation. The timer starts as soon as one of the impact sound sensors receives the impact sound oscillation, and stops as soon as both impact sound sensors receive the impact sound oscillation. An independent claim is included for the impact sound oscillation detection device.
